42 Claims. (Cl. 1 3) This invention relates to stapling machines.

It is an object of the invention to provide a stapling machine in conjunction with which is associated means operable automatically, and simultaneously with the stapling apparatus, to puncture members disposed in connection with the machine. The puncturing operation may be made effective to produce an opening extending entirely through members properly disposed.

1.o By such apparatus, the operation by which a member such as a bag is sealed closed also results in the formation in or the association with the bag of means by which the bag may be located and/or supported upon a proper carrier. Appli- 1,-, cation of the invention has been found useful Where packages of small articles are sealed closed, to provide, simultaneouslyiwith the sealing operation, means by which such packages may be as sembled on a display card.

For that purpose, in association with the plunger which drives staples through members to be secured together, is carried a punch. On downward movement of the plunger, the punch also moves into position. On a base arranged to receive members to be secured. together, are disposed suitablecooperating means for association with both plunger and punch.

In one of its specific phases, the invention is applied in association with a stapling machine in which the staples are loaded into the machine by insertion at the end of the machine to which they are fed for their positioning in a securing relationship. In a machine of this type, after the staples have been inserted, a door is moved to a 3'5 closed position, thus providing a guard for that end of the magazine. By means of such' guard, movement of the staples out of the magazine, except when a predeterminedseries of steps has ensued, is prevented.

40 The punch, in a construction of this type, may be extended immediately in front of this door, a construction which, therefore, normally would interfere with, and even completely bar, access toA the magazine. It is an object of the invention to arrange the punch in a manner such that, even though normally the punch may operate for its desired purpose, still, whenever necessary, the several parts may be manipulated so that the punch nolonger affects access to the magazine,

permitting release of the door Whenever desired. In stapling machines of the type here dealt with, staples are carried, side by side, in a magazine; they slide forwardly, step by step, asindividual staples are used. It is an Object of the invention to provide means for signalling to an operator the condition of the supply of staples in such a magazine. Generally a slide is disposed in connection with such a magazine, functioning to impel the staples into a position from which they are driven into engaging relationship with the members to be secured thereby. For the purpose here stated, means may be associated with magazine and slide to cause an indication to be given to the operator at the time the number of staples becomes reduced to a point where refilling is necessary. Such an indication is especially desirable since, at the end of the feeding operation, that is, when' the slide is moving the last few staples into the vicinity of the plunger, those few staplesare hidden from the view of the operator. Since he has no opportunity to determine accurately the condition of the supply of staples in the magazine, he must gauge the moment when relling becomes necessary.

In one type of stapling machine, a magazine,V provided for` receiving staples to be fed as they are required, is lled through the front end of the machine, the front-end of the magazine being left open. Through that open end is effected reloading of the magazine. At that end, in the customary manner, is disposed mechanism for driving individual staples into securing relationship. A proper guard for the end of the magazine may take the form of a door, arranged to dene a, guide for means such as a plunger which may be made effective for driving the staples into position. It is an object of the invention'to provide as, and in association with, such a door, a memberjof substantial rigidity, not deecting to any appreciable degree under the action of the apparatus, and providing a guide for staples and plunger of substantially constant dimensions during use. As an element of a construction of this type may be introduced mechanism formaintaining the door closed, which mechanism, in this association, will assure that the door be, at all times, retained in position without any movement until released, not by a pressure against the door itself, but only against the mechanism provided for maintaining the door closed. While a door of this type is, for certain purposes, capable of construction from sheet metal, to assure the properties of rigidity desired, it and the latching mechanism are formed by casting or drop-forging.

One specific type of staple described herein has relation to a use for securing together a plurality of members, such as sheets of papers, piled one upon the other. Such a staple generally has a Cil - essing or manner of manufacture.

`pair' of legs which extend through the several layers and are bent or clinched under the bottommost sheet. On many occasions, it is desirable to break down this xed association by removing the staple. It is an object of the invention to provide a formation of a staple, and a stapling machine for producing such a staple, whereby, after the staple has been driven, by its very formation, it will present means facilitating firmly gripping the staple when it may be desired to remove the staple from an association of the type discussed. Furthermore, the means so formed may be made to provide a hook .or similar element for the support of the articles secured together by the staple. A formation of the character specifically applied for the purposes of this inventionhas been found especially desirable in connection with staples intended to be in position only temporarily. Such a formation immediately identifies such' staples, notifying the user that such a staple was intended to be removed. Where the apparatus may be madev effective -to impress such an indication into a temporary staple, the machine may have associated mechanism permitting use of the machine for the production of staple formations both of the temporary and ofthe permanent character.

Staples used commercially usually are supplied in prepared sticks, that is, the staples are arranged in side by side relationship, and are secured in that relationship by a particular proc- In the use of such sticks, before the staple is driven, it is separated from the stick. Then there ensues an interval in which the staple stands alone, and is guided to the driving position. If, during that interval, it should, for any reason, be determined not to drive the staple, the staple so separated might affect the mechanism to clog its further operation.

It is an object of the invention to provide means by which a staple so separated will be given support during the period it is being moved by the driving mechanism into engagement with members to be secured thereby, the means being effective so that, if the staple does not complete its movement into engaged relationship, that support will continue, the staple being returned within the apparatus for use on a future occasion. Means for such purpose may take the form of a retractor against which the staple is pressed by the driver, the retractor moving downwardly together with the staple. The construction of the retractpr may be such that the staple will be supported upon-a ledge so that the staple will have substantially no tendency to move beyond the retractor ledge until the instant at which the staple is being engaged with the members to be secured thereby.

Particular attention will be paid to that type of stapling machine in which the staples are assembled in the magazine by insertion through the end at which the driving plunger is located. In a stapling machine of this character, it is an object of the invention to arrange a slide by which the staples are impelled into position for engagement by the plunger so that the slide is retained in its association with the magazine at all times. Forward impulsion for the slide is secured from a spring housed entirely within the magazine and therein retained. 'I'he operation of loading the magazine is simplified to a high degree, the spring being released from the necessity for manipulation during 5111.311 lOTfLding step.

Before staples are inserted into the magazine, the slide is merely retracted to a position at which it is latched. The slide, at no time during use of the machine, becomes separated from 4' the apparatus; it, therefore, can become neither lost nor damaged by separation from the apparatus. The spring itself is out of harms way, and also is free from the tinkering to which a spring open for manipulation is subjected.

In a stapling machine of the character here concerned, the staples are fed automatically to spring is housed therein, and as a result of the operation of the machine itself, is subjected to varied stresses the ultimate result of which may be the distortion of the magazine and the various parts of the apparatus therewith associated. Such a result would carry with it the throwing out of alignment of the various parts of the apparatus, and the consequent inability of the apparatus to function. It is an object of the invention to form a magazine and a body for a machine of the character herein discussed of great rigidity. For this purpose, these parts are made of die-castings or drop-iorgings, the bore of the magazine providing the retainer for the spring which then acts against and propels a slide for feeding the staples into driving relationship.

The manner in which the body of the machine is formed provides for the insertion, into the bottom of the casting, of a rigid bar of metal. This bar of metal, so inserted, acts against the walls of the body, rigidifying them along their length. At the forward driving end of the magazine, the bar may be effective in providing a pair of walls, for cooperation with the driving mecha-4 nism, to sustain the legs of the staple when it has arrived at the most dangerous stage of the driving operation, that is, when the points of the staple are penetrating the material the staple is to secure together.

It is desired to construct the main body portion of the machine and the magazine of diecast metal. Since die-cast metal might be too soft to resist the abrasive forces acting when driving staples, it is an object of the invention to associate, with the die-cast body portion, means at the forward end of the magazine to function as positive guides, disposing walls between which and against which each staple will pass and press when being driven and immediately-as the staple engages with material to be secured thereby.

In conjunction with a construction of the type here set forth, it is an object of the invention to provide a member which will cooperate with the walls disposed as guides so that a complete path for the staple will be defined. Such member is of rigid metal in which the factor of springiness has been reduced to a small or entirely negligible degree, as, for instance, by drop forging. A member for such purpose may be in the form of a door, as above set forth, and pivoted at a side of the magazine so that it may be swung to contact the end'of the magazine and close the saine in forming the guide for the staples.

With a construction of this character, the staples are continuously driven against the door by zine. If the door, be made. of resilientmaterial, this continuous pressure, aswell as the lateral pressure exerted as the staple is crushed when driven into position, finally will result in bulging the door outwardly and out of the true guideforming relationship. Consequently., the apparatus will become inefiicient as the path of wire staples such as generally used must be accurately dimensioned. Such bulging of the door, by increasing the width of the passage, willV destroy the accuracy of alignment between the driving v.element and the staple when they move together through that passage. With a door constructed in` accordance with the invention, and securing `means for the door as here described, no such deformation of the door may occur by reason of the rigidity of the member and the manner in which such a member is locked against outward movement and against play. The continued -sidered, there is a magazineand a base, the

magazine being pivotally supported upon theA base. For such a construction, it is an object of the invention to position a spring between magazine and base to retain the magazine spaced away from the base, with a pivot post made by a simple device such as a pin which will provide, by an interlock between spring andpin, against accidental separation of the pin from the apparatus. vSuch separation may be effected only by a manipulation of the pin itself into a position other than that which it normally sustains in-the apparatus.

Retractors such as here discussed, that is, de-

' vices operating in conjunction with the driving means, function to sustain a staple during its downward movement, to keep the staple from i falling away from the driving blade during that downward movement, to-sustain the body portion of the staple during the driving action, and to counteract tendencies of the staple to bulge downwardly at its intermediate wall portion.

' The force exerted by a retractor may be resolved into a. number of components. One of the components is an upward one; the other is downward, and outward against the door. The first is the one sought. The latter is unnecessary and, in fact, may tend to disalignthe staple during its downward movement.

It is an object of the invention to construct a retractor so that the major portion of its force will be upwardly against the staple, and to avoid, to as great a degree as possible, the outward, distortingcomponent. For this purpose, the retractor arm may be bent intermediately thereof to form an upwardly extending shoulder. It is desirable thatthe retractor, atrest, may not extend up into the path of staples along the magazine. In such position, it may exert an undesired' frictional effect against the ready movement of the staples, or may interfere with the operation of loading the magazine with staples o through the front end. To guard against this condition, the arm may be provided with a pair of ears which stop upward movement of the retractor arm, engaging against the bottom face .of a channel upon which the staples ride.

Where staples are propelled, as here, toward an end of a. magazine through which access is had for refilling or similar purposes, the protection of the user against accidental release of the staples is desirable. It is an object of the invention to provide means to restrain staples within such a magazine against free movement except when certain preliminary steps are taken to ef'- fect such freedom of movement. The staples are normally engaged by a device restraining forward movement even against the action of the propelling spring. However, on operation of the drivingl plunger, the staples are left free to move, being again'restrained when the plunger `returns to the beginning point for a driving movement.

Other objects of this invention will hereinafter be set forth, or will be apparent from the description and the drawings, in which is illustrated a stapling machine capable of effecting certain of the phases vof the invention herein set forth.

Fig. 13 is a view of the detail, partially in section, partially in elevation, illustrating a modified vom form of the driving head and anvil of apparatus such as shown in Fig. 9.

On the drawings, a stapling machine I is shown as including a base I2, a magazine I4, a driving mechanism I6 and an anvil I8. Base I2 may be a unitary cast structure, whereby a degree of rigidity, necessary to withstand the forces applied by the driving mechanism, is secured. The base includes, at its forward end, section 20 of increased thickness: with this section, the anvil is associated.

Toward the rear of the base, bearings in the formlof a pair of lugs 22, through which are formed aligned openings 24, are provided. A pivot post 26 is received through the openings. As a part of the magazine there may be a pair of downwardly extending lugs 28 through which aligned openings 30 are formed, in a similar manner. With lugs 22 and 28 properly related, as here with lugs 28 within the confines of lugs 22, the openings are all brought into alignment. Through the aligned openings is passed post 26, to pivotally mount the magazine upon the base. Lugs 28 may be formed at their rear ends with legs 32, to serve as stops, limiting upward movement to a predetermined level of the forward end of the magazine.

The magazine and casing 34 for the driving mechanism are here made as a single casting 38. At the front end casing 34 is defined; from it extend rearwardly two parallel walls 38 which, at their rear ends, are bonded to each other by a pair of cross-ribs 40 and 42, both of which are spaced apart at bottom 44 of the magazine portion of the casting. The cross-ribs serve to strengthen the casting at this point. A leaf spring 46, inserted through an opening 48 between the ribs, extends rearwardly to the extreme end of the magazine. 'I'here it turns up'- wardly, providing an end wall 50. Portion 52 of the spring, outside the magazine, after passing through opening 48, extends beneath post 26, and then into engagement with top face 54 of the base. In this. manner, it is made efl'ective for compelling downward movement of the rear end of the magazine and, therefore, upward movement of its forward end.

Post 26 preferably is notched, as at 56. The spring itself may have asmall, upwardly turned lateral lug 58. When the post is in a proper relation, the lug will seat in the notch, thereby restraining the post against lateral play and assuring that the post will not become separated from the apparatus during use. The outer end of the post may be formed with a squared Section 60, forming means to grip the postv and rotate it. When so manipulated, lug 58 will be cammed out of notch 56, and, therefore, out of the engaged relationship. The post may then be slid outwardly, and thereby be separated from its bearings, liberating the casing and magazine from the base.

Walls 38, at their upper ends, are inwardly turned into flanges 62. Between the bottom ends of thelwalls is positioned and secured a bar 64. Bar 64 may be secured to the magazine by any desired device, as by rivets 66, to secure the utmost rigidity therefrom. The bar preferably is of considerable thickness; in one form, it is of bar steel, functioning to rigidify the otherwise Widely separated walls, together with the ribs. The bar extends to the forward end of the magazine, just beneath casing 34, at which it is cut away in a manner hereinafter to be referred to.

Seated upon the bar is a channel member 68 of slightly smaller dimensions than the passage formed by walls 38 and bar 64, the diiference being sufficient to provide a guideway for reception of slide 12 and staples 14. Member 68 may be secured to bar 64 in any desired manner, such, for instance, as spot welding.

Within the bore 16 of the channel is housed a coiled spring 18. This spring, at its rear end, is stopped against wall 50; at its forward end, the spring bears against a down-turned leg 80 of an oscillatory member 82 carried by slide 12. The body of the slide itself is preferably of U-shaped construction, having its legs 84 seated within the guideway and its cross-wall 86 riding over flanges Member 82 may be formed from a stamping, in

which case its rearmost extremity may be a iinger 92 for insertion beneath ear 90 to retain that portion of the member rmly associated with the slide, while permitting lateral oscillatory movement thereof. Forwardly of the finger, the stamping, may be turned upwardly, and then downwardly again, to provide a thumb piece 94 by which member 82 may be manipulated. y

At its forward end, the stamping is turned down to form leg 80. A slot 96 is formed in crosswall 88, through which leg 80 passes. Flanges 88, similar to flanges 62, cooperate in defining guideway 10. Leg 80 has a reduced section 98 to permit its extension through slot |00 between flanges 88. By this relationship, the leg is retained against outward movement, the leg within the channel being increased in extent to conform substantially to the effective cross-sectional area of the bore 16.

Staples, positioned in the guideway, are impelled forwardly by spring 18 into cooperation with driving mechanism I6. Closely adjacent the rearmost portion of one flange 62 is provided a notch |02 into which a laterally extending finger |04, formed as a part of thumb piece 94, may, by swinging member 82 laterally, when slide 12 is retracted sufficiently, be engaged. The slide will then be retained against the action of spring 18, making the slide ineffective. When the slide is so retained, the magazine may be loaded with- .during the driving action. The bar, at this forward end, may be cut away at |08, for a purpose hereinafter to appear, leaving lugs IIO, the forward ends of which denne faces |06. The thickness of bar 64 is substantially that of the height of one of the staples, the purpose being to assure a rm backing wall for the staple immediately at the time'that driving and clinching action occurs.

Above lugs IIO is the end of member 68, likewise cut away, with its end edges disposed substantially in the same plane as lugs IIO. While these end edges are of small thickness, this is sufficient to define a guide in the period during which the staple is passing the e'nd edges. In

that period. no force otherthan the propelling 1 force is being exerted upon the-staple. The end edges merely cooperate with door I I2 in defin- 'ing a passage I4 through which the staple moves 'through passage I |4, may have support to assure.

downward movement under proper guidance, there is required an accurate alignment of lugs ||0 and these end edges. To.` counteract any tendency on the part of the staple to engage l against the top edges of lugs ||0, and to assure that such engagement will not take place, even.'v

with the accurately dimensioned parts used in such apparatus, the top edges of the lugs are bevelled as at ||6, providing a cam face for moving the staples outwardly on downward movement.

The ends of member 68 and-bar 64 thus define one wall along which a staple rides during its downward movement. These parts, -being separate and distinct from the die-casting, may be receive snugly the moving staple and the driv-l ing means. 'Ihese plates extend up beyond the top of member 68. Therefore, during the entire time of movement of the staples and when beingdriven, the plates continuously constitute for the staples a wall having great resistance to wear.

The forward end of the magazine may be closed in any manner'so long as this relationship of parts is secured, and so long as passage ||4 is' 2 maintained properly dimensioned to limit movement therethrough to but a single staple at any one time. In order to permit fllling of the magazine through that end at which the staples are separated from the supply and driven into engagement with the members they are to secure, the means provided for closing the end of the magazine preferably is made in the form of a door II2.

The door, for purposes herein stated, may be made by drop forging, assuring great rigidity and resistance to distortion. 'I'he door may have a centrally grooved portion |22 from which extend away a pair of faced .wall sections |24. A t the end of each faced wall section is provided a mounting means, in one case being comprised of a pair of lugs |26 constructed for the reception of a pivot' pin |28 carried by lugs |30 at the end of the cast magazine portion. A coiled spring |32 operates normally to rotate the door to open position, the door cooperating withthe casting to limit its rotational movement.

At the other section |24 a pair of lugs |34 carry a pin |36, leaving an opening |38 betweenthem. At the associated portion of the cast magazine section there is provided a pivot pin |40. A latch -|42, pivoted upon the pin-,vis normally springpressed outwardly by a spring |44 engaged between the latch andthe wall of a recess |46 in 3which the latch is seated. The forward end of the Alatch may include a hook-defining element |48, the extreme outer face of which has a cam surface |50.v Element |48 has a recess |52, the

walls of which are turned outwardly for a purpose to appear.

When the door is moved ,to bring pin |36 against surface |50, the latch will be-forced backwardly against lthe action of the spring in recess |46, finally bringing pin |36 so that it may engage within recess |52. Spring |44 will then force the latch outwardly, the recess partially encompassing pin |36. The latch may be provided with a slightly raised element |54 extending a small distance out of the recess, to function as thumb piece. By pressing on' element |54, the latch may be depressed into the recess to release engagement of pin |36 and the latch; When the door is retained closed, staples within the magazine will be driven toward grooved portion |22. Recess |52, by its formation, will' be unaffected by such force which will be incapable of separating the pin from its engaged relationship. In fact, increased force will make the recess more positive in its retaining function.

Faced sections |24 seat against the end edges of plates ||8 and themselves define the front walls of passage ||4. Grooved portion |22, .together with the cut-away character of the bar v and the channel, all accommodate a retractor |56,

associated) with the apparatus to support the staple in its downward movement. -This retractor preferably consists of side wall sections |58 forming bearings for a pivot pin |60, sections |68 preferably being a pair of lugs formed as an integral part of retractor arm |64. Coiled spring |66 normally forces the retractor upwardly so that the arm will be in engagement with the bottom face of flanges 68.

, Arm |64 is angularly deformed intermediately thereof,as at |68, so that its end |10 extends upwardly at a sharper angle than does the section pivotally mounted on the pin. In this manner, the pressure exerted by end |10 will have its greatest, and, preferably, substantially all of its force directed vertically upwardly, eliminating to `as great a degree asv possible the forward component. AWith the end bent up in this manner, Y*

and the menoer, facilitate any repair that maybecome necessary by reason of clogging of Staples. The entire groove is, by such cutting away, made accessible throughout its entire extent for any such repairs.

Casing 34Iprovides a guideway |14 for thereception of plunger. |16 of the'driving mechanism. The plunger includes a` cap |18, and a body section |80, united tothe cap in anyL desired manner, and extending within the guideway. Preferably, the body section is bored, as at |62, for the reception of a coiled spring |84, the end of which seats over a nub |86 on bottom wall |88. A side wall of the body is cut away to form a slot |92, this slot being positioned in adjacency to an opening |34 in wall |96 of the casing. A leaf spring |96, retained upon a pin 200, carried between ribs 202 of casing 34, extends upwardly andl has a squared section 204 inserted through opena portion of the casting, or by the upper portion of the slot.

At the front face of the plunger, there is provided a protuberance 206, preferably a pin riveted in the -body portion. Upon this pin is intended to be mounted a driver plate 208 lof practically the same thickness as the staples which are to be driven. The upper edge of the plate extends up to and in close adjacency to a shoulder 2l0; 10 the cooperation of the upper edge of the plate and the lower face of ythe shoulder results in the retention of the plate against oscillatory movement.

The plate, at its lower end, has a reenforcement 2I2 provided thereon, this reenforcement having the character of an additional piece of cated as for temporary purposes, but .generallyl applicable for retaining members together, the anvil has an element 2I8 raised above the plane surface of the anvil.

When the driving plate forces a staple down and body portion 220 of the staple is pressed against element 2|8, the staple will be shaped to conform to element 2I8. The end'edges of theA driving blade may be cut out, as at 222, to cooper- 'ate with3 element 2 I8, during such driving operation, and with the element, to impart to the staple the humped formation 224 shown in Fig. 10. In the same manner, retractor. arm |64 may have a notch 225 cut in its end so that the arm will clear element 2I8 without damage.

In certain specific applications of such apparatus, element 2I8 may be found unnecessary, and only cut-out 222 be used, as where staples are to be driven over small objects, such as wire, to retain those -objects in association with a l cardboard plate or a similar element. In such case, the wire cooperates with the anvil and the cut-out to: produce the humped formation 224. 'I'his humped formation, where formed by the coaction of element 2I8 and cut-out 222 without the intervention of wire element, and extending free of the member` in which the staple is fastened, may, by making the hump large enough, function as 'a hanger. Also, such a humped formation provides'a handle means by which a so-called 60 temporary staple may be grasped, in order to remove it. Such a device eliminates the danger of breaking finger-nails in 'separating such staples.v 'Ihe extension of the metal of the staple, 65 produced by this formation of a hump, facilitates breaking the staple, where such is` desired to effect separation. A i

The anvil may be a member 226 having a guide 228 at its lower face for reception in a guideway of the clinching surfaces 214, 216 may be made 75 effective.

V250 across whichfextends a pin 252.

For certain purposes, it may be desirable to make thegplunger operate simultaneously not only to drive the staple but also to punch a hole through members which are so to be secured together. For this purpose; a pivot pin 236 is provided adjacent thetop of body |80; upon this pin may be pivotally mounted a punch 238. This punch extends downwardly and is guided by a spring arm 240. When the magazine is brought down against members to be secured together.,

and then the plunger is depressed, punch 238 will be propelled downwardly with the plunger, sliding through the guide formed by arm 240, and then will cooperate with die 242 in base I2 to punch a hole through the member. Since the punch extends down below or substantially to the same level as plate 208, the lower end of the punch would, at all times, be in front of door H2, and would interfere with accessibility to the front end of the magazine and its loading. Arm 240 is constructed to limit movement of the punch merely in one direction, frictionally restraining it against movement in the other direction. However, the punch, by pushing it sideways, is released from engagement with the spring bar. Then the door may be liberated for access to ,the magazine.

In order that the position of the end edge of slide 12 be, at all times, known to the operator, especially when the end edge of the slide travels within casing 34 and is no longer visible, means are provided to give warning. 'I'he slide may carry a prong 244 which,l at a suitable position, will engage aI vibratory member 246. When prong 244 passes member 246 and releases it, the member will emit a note of warning so that the operator will understand the apparatus requires reloading.

In conjunction with a staple feeding mechanism of the type`- indicated, it is desirable to have means provided which, when the door is opened, will restrain the stap1es agai nst outward movement. 'Ihis is especially true in connection with a slidev which, if inadvertently released might propel a supply of staples through the 'open door. For this purpose, mechanism 248 is used. Within the body of the casting is formed a recess Upon this pin is pivoted an arm 254 formed with a ledge 256 against whichis engaged a spring258. Ex-

tending upwardly from the lledge is a nub 260 which cooperates with an indent 262 in the top wall of the recess to. maintain spring 258 in position.

Lower face 264 of the arm is formed with a plurality of teeth 266. These teeth, by the action of spring 258, are forced into engagement with the top surface 268 of the stick 210 of staples carried on flanges 88. By this construction, the teeth, when in engagement with the staples under the action of spring 258, effect a braking action against movement of the staples forwardly in the direction of the open end of the magazine.

Arm 254 has a cam end 212 at its forward end, the end projecting directly into the path of driver plate 208. The projection of end 212 is into passage I I4 through which plate and staple move, but, of course, above that portion through which the staple 'moves'. As the driving plate descends, it first engages surface 214 of cam end 212, forcing the arm and ledge 256 to pivot upwardly. removing teeth 266 out of engagement with the staples. Now the staples may move forwardly under the action of their slide and its spring.' The driving plate, descending still further, projects the staple intothe properly secured relationship.

During that period, the first staple of the Vstiel:

is maintained in contact with the driving plate,

but, by reason of the width of the passage, may not enter. f As the driving plate is retracted and moves above anges 8 8, the staples still remain Afree of teeth 266, and are propelled so that the upon spring 258 will drive teeth 266 again into engaging relationship Ato -top surface4 266, retaining the stick-against forward movement. The staple now will be positioned to be engaged by the driving blade upon its descent; if the door be open, the staples will be restrained against forward movement. To load the magazine, it is merely necessary to push the stick through the magazine front end. The teeth will not prevent movement of the staples into the magazine, but

l function only to prevent movement of the staples outwardly of the magazine.

If it be desired to clear the magazine, the insertion of a tool after the door has'been opened away, to engage against end 4212, will cause upward movement of the teeth, and release of the engaged staples. v

In the construction shown in Fig. 13, in order to assure the proper cooperation `of punch 238 and the staple-driving means with the anvil,

there is made apart of the anvil and magazine, means for'assuring thepositive relationship of the part continuously during driving and punching action. This is illustrated in Fig. 13 by the construction of the anvil 216 and the guide 218 carriedfrom the magazine. This guide may be made as an L-shaped member, one leg 280 of which is secured in any desired manner to a bottom face of the magazine. The other leg 282 extends within av slot or a groove 284the lateral walls 286 of .which are spaced suflciently apart to assure theretention of leg 282 and, therefore,fthe magazine against any material lateral displacement throughout lthe vertical movement of the magazine with relation to the base. vIn anvil- 216 is also provided an opening 288 with-which will cooperate the punch 238. A lso there is carried the die faces 290 against which the staple ends will be pressed -during driving. In this manner the punch and staple-driving members are all assured a denite relationship continuously during the drivingand punching `operations. The leg 282 may also serve as a limit for determining the position of any element placed upon the anvil and thus al of the position with relation to that element of the nally punched hole and the secured staple.

Many other changes could be effected in the particular apparatus designed, and in methods of use set forth, and in speciic details thereof, with-- out substantially departing from the invention in tended to be defined in the claims, the spec'ic descri tion herein being merely to illustrate an operative embodiment carrying out the spirit of the invention.
