ApplicationApriL 29, 1948, Serial No. 23,880

6 Claims. Cl. 16462) invention relates to new and useful 1m.- provements in power driven cutting apparatus, and, more particularly, aims toprovide a novel and. valuable cutting machine incidental. to. the operation. of which an. article, to be subdivided by a; cutting stroke; is manually placed in a receptor, there retained during the cutting; stroke, manually removed after completion of such stroke;

As: the invention. is' herein shown, it: is applied to: a. machine for making fillers for shoulder pads. Asia well: known, shoulder pads are generally triangular in outline, and a practice in. making the fillers: for. suchpads. is to subject a. substantially square: mass. of. quilted, matted. or plural-layer softly flexible: material to a.- single cut diagonally of. the square to produce two like substantially triangular fillers each for a different shoulder paid.

Said cut must be quickly and cleanly made, and desirably by acircular cutting knife. power driven at; high speed. A disadvantage, and in.- deed a serious danger, which itis the object of. the present invention entirely to obviate, has been the chance of. the knife cutting the fingers or hand of the attendant, during the cutting operation, or during the placement of. said mass in position. for being. out, or during the removal of the cut parts.

By the presentinyention, a. receptor is provided for said. mass, which receptor is, mounted for movement. toward and away from the attendant, under control of the latter; in. combination with a placement of the field of operation of the cutting: knife such that, with said knife under continuous drive from a power source, it is impossible. for the attendant accidentally to become: injured by the knife. The arrangement is such that when the receptor is positioned for receiving. the material. to be workedv on, or. for removing therefrom such. material, either before or after having been worked on, the receptor is between the attendant. and said field.

Preferably, according tothe invention, the receptor is an open-top box; with a hinged. lid, andslidably mounted for movement away from the attendant into a roofedeover housing; at the field of operation. of the cutting knife, and then, moreover, with said lid. down over the top of the box.. Thereby, with. a. circular knife, the cutting be performed concurrently with. the travel of the box: into the housing and; thence toward the: far end of the. latter; Atreadle or. the. like may be used to reciprocate the box, and prefer ably in such way that; a. foot thrust on said treadleisnecessary to start the box toward and cause the box: to make complete entry into the housing, and with a spring means or the like for acting automatically to return the box to its position immediately in front of theattendant on releasing the treadle from said thrust. In the latter: connection, means are provided for readily' adjusting the tension of said spring means..-

Also, as the invention. is preferably carried out, with said lid hinged and. normally spring urged toopen position, a device is provided whereby when the lid is manually closed down over the top of the: box, with the latter at its forward position. and. just after the attendant has placed the material to be worked on in the boX, the lid is: latched closed; but, furthermore, to take care of the casewhere the attendant has neglected thus manually to close the lid, an arrangement is present whereby, almost at the instant the box is started inits travel toward entry into the housing, the lid, if not closed, is slammed down.

Means are also provided whereby the spring means. for normally urging the lid toopen position: is easily varied in tension, to modify the force of the. spring action,

Means: are also provided whereby, when the box is returned. to its position in front of the 7 attendant, following issuance of the box from. the

housing and so away from the field of operation of the knife, the aforesaid latch or the like is automatically released, thereby causing the cover to fly up to a vertical position or therebeyond; and in the latter connection means are provided, preferably carried by the housing, for holding the lid in. the position just-mentioned during all: the while the box. is directly in front of the attendant.

Further, means; are provided. whereby the means for causing the cover tofly up as last described may be adjusted,- in order to have such lid. lifting occur at a point in the forward travel of; the. box best adapted for the convenience and c'el'erity of motion of a particular attendant.

Variousother features and advantages of the invention will be pointed out or become apparent hereinafter;

For further comprehension of the invention, and of the objects and advantages thereof, reference' will be had to the following description and accompanying drawings, and tothe ap pended claims in which. the-various novel features of the invention. are. more particularly set forth.

In the accompanying drawings forming a materialipart of this disclosure:

Eiga. his a.- perspective' view, looking. in a slightly upward direction, of an embodiment of the invention as now favored.

Fig. 2 is a perspective view, looking down on the receptor, the housing, and the trackway guiding means for the receptor, and fragmentarily showing the table on which these parts are carried.

Fig, 3 is a top plan view of the receptor, with the lid closed.

Fig. 4 is a vertical section, taken through the machine on the line 4--4 of Fig. 2.

Fig. 5 is a detail View, being, on an enlarged scale, a section taken on the line 5--5 of Fig. 2.

Fig. 6 is, on a more greatly enlarged scale, a fragmentary perspective View; this view also being a section taken on the line 6-6 of Fig. 3.

Fig. 7 is a section taken on the line of Fig.6.

Fig. 8 is an enlarged detailed View similar to a portion of Fig. 4, but with the recepto in its nearly completely forward position.

Fig. 9 is a partial horizontal sectional view taken on the line 9-9 of Fig. 8.

Referring to the drawings more in detail, a table top H! is suitably secured to and at the tops of a pair of end supporting structures each comprising an upper bracket I! having two dependent slotted legs l2 and a lower skeletal casting i4 having feet l5 for resting on a floor. The four slots carried by the legs [2 provide, in combination with the bolts indicated and suitable apertures through the tops of the casting M, a means for readily changing the level of the table top In.

The lower skeletal casting has standards l4 Each standard [4 has a cross member Hi, to which members are suitably secured the opposite ends of a plate-like bar [1 for suspending as shown the motor l8. Also extended between the two standards is a tie-box I'I of L-shaped cross-section, and in which may be laid the main length of a cable 18 containing the wiring connections to the motor; this cable going to a switch 253. From said switch there is a cable 2! containing the wiring connections to a plug 22 for insertion in a nearby current supply recepacle.

The side of the table top H] faced in Fig. 1 is that at which the attendant is positioned, either standing or on a suitable seat.

The cutting knife 23 is a circular one, fixed on a short shaft 24 carrying a pulley 25 and suitably journalled in and near the top of a columnar mounting 26 suitably secured to and upstanding from the bar H; and also suitably secured to and upstanding from said bar is a bracket 21 on which is movably mounted a carrier 28 for a knife-sharpening grinding wheel 29, the arrangement being such that, with normally said wheel out of contact with the knife, a spiderlike handle 33 may be manipulated to dispose the wheel 29 against the knife for sharpening the latter, then giving the knife a power drivenrotation. The knife 23 is driven, in the direction of the arrow 3| of Fig. 4, by means of a belt 32, between the pulley 25 and a pulley 33 fixed on the motor shaft.

To the top casing of the motor I8 is suitably secured a rectangular plate 34, of sufficient width to have projecting marginal portions at opposite sides thereof. The suspension of the motor from the bar is by way of said plate and a plurality of fairly long bolts, and nuts, as shown in Fig.

-1, so that by use of different nuts, washers, collars or the like, as shimming or spacing elements 4 between the bar l1 and the plate 34, the motor may be raised or lowered relative to said plate, to effect a belt adjustment, as to take up slack therein.

The table top It, for projection of the knife therethrough and up above the same substantially as best shown in Fig. 4, has a straight fore and aft extending slot 35. Parallelling this slot and for guiding a receptor 36 in its sliding movements are a pair of rails 38 here shown as being thin stock channels, arranged with their grooves facing each other.

The receptor includes a rectangular bottom plate 39, opposite edge portions of which are slidingly extended into the grooves of the channels 38. The plate 39 at its upper side and along its front and rear ends carries bars 40 and 4| secured thereto. The receptor 36 further comprises a lid 42, also in the form of a rectangular plate; four bars 43 outlining a diamond somewhat elongated laterally of the line of travel of the receptor, these bars 43 suitably secured to and upstanding from the plate 39; a hinging means for the lid and as a whole marked 44; four bars 45 outlining a similar but smaller diamond, these bars suitably secured to and dependent from the under side of the lid; and a means, including a pivoted latch member 46, for coacting with the swinging end of the lid for holding the lid closed.

The bottom plate 39 of the receptor is slotted as at 4?, such slot being directly above the slot 35 through the table top l0; and above and in line with the slot 4'! there is a space 48 between the adjacent ends of the two bars 43 which converge toward the bar 4! (see Figs. 2 and 3), a space 49 (see also Fig. 4) between the adjacent ends of the two bars 45 which converge toward the bar 4|, and a slot Bil through said bar 4|. When the lid 42 is down on the bars 4B and 4|, the space 48 and the slot 5!], these two always aligned with each other and with the slot 41, are also aligned with the slot 49.

The slots 35 and Si] and said spaces 48 and 49 are such, relative to the diameter and center of rotation of the knife 23, that said knife can have a cutting stroke through the material in the receptor, along the entirety of a central length of such material, in the direction of travel of the receptor 36, incidental to a movement of the receptor from its material feed-in and take-off position shown in Fig. 1, to its position shown in Fig. 4; it being understood in this connection that during said cutting stroke said material is lying fiat in the diamond shaped pocket defined by the inner periphery of the diamond shaped structure provided by the bars 43, with said material squeezed down marginally thereof by the bottoms of the four bars 45.

The housing 5| overlying the field of operation of the knife 23 comprises side walls 52, 52, a back wall 53, and a roof wall 54. The housing 5| is open at its end facing the attendant, and the rails 38 extend through such opening.'

For manual control of the back and forth sliding movements of the receptor 36, the bar 40 thereof has a recess 55, engaged by a finger 55 rigidly carried by and upwardly projected from the top of a lever 51 rockably mounted on a rod 58 secured at opposite ends to the casting it. At the lower end of the lever 51 is a rod 59, having portions extended on opposite sides of the lever. so that either of these extended portions may be used as a treadle, to be pushed on by the heelbreast of a shoe worn by the attendant, thereby to swi g the l e 5 f om. its normal position ar a-242 iaslin Fig. .1, and as shown .in dot and dash lines in 4), 7110 its .full-line position in Fig. 4, to movethereceptortfi rearward to engage the contained pad with the knife 23.

.As soon :as said thrust on the vtreadle is released, the lever 51 efiects automatic return .of .the receptor to normal position, by swing back of the finger .56 toward the attendant, thereby to withdraw the receptor from the housing 5| and advance the .bar 40 of the receptor to the dot and dash location indicated at 4B in Fig. 4.

.Saidswing back of the lever 51 is effected by a coil spring .59., one end Bl of which (Fig. 1.) is engaged with said lever, and the otherend 62 of which is engaged with a neck 63 offset from a collar 64. This collar, which with the coiled central portion of the spring 69 embraces the rod .58, carries a set-screw 65; the neck 63 being tubular and internally threaded for taking said .screw, and the latter being used to loosen its grip on the rod 58, for ready variation of the tension of the spring vtill by turning the collar -64 on .the rod .58, and for then clamping the 001-,

lar to hold the spring under the tension desired.

The latch member 46 is pivoted between a pair of offset ears carried .by a bracket 86, see particularly Figs, 8 and 9, secured to the front side of the -bar 40; said member 45 .being shaped .asbest shown in Fig.8, to provide a space for the accommodation of an expansile coil spring -61 to :urgesaid member to the position-shown in full lines in Fig. 4 and in .Fig. 8, and to present a downwardly sloped tail 68.

The tail 68 of the latch member is for engaging 'E'StQP-baI-GS, for arresting the receptor 3-5 when advanced to the limit of its travel toward the attendant. As the receptor completes this movement, the latch member -46 is engaged at its tail by the stop-bar, and the latch member is rocked,

as indicated at 46' in Fig. 4, whereupon the receptor lid 42 is by a spring means associated with its hinge means swung up, as to the position indicated in Fig. 4 at 42', and there arrested by impingement against a pair of cushioned stop pieces forwardly projected from a wall H atop the housing 51 and secured thereto as by way of an angle brace 12.

Thestop-bar 69 is adjustable on the table id by means (Figs. 1 and 4) including a pair of slots l3 and M through the table, and bolt and nut elemerits as indicated at and i5.

Referring now to the hinge means 44 for vmounting the receptor lid 42, and particularly in this connection to Figs. 6 and '7 (with occasional cross references to Figs. 2, 3 and 4), a strip ll, as long as the hard] but only about half .as wide, and of the same thickness as the lid 52, is suitably secured on said bar so as to provide a step 18. The hinge itself, this marked '59 in'Fig. 7, is substantially of the same length as the bar H.

The long pintle 89 of the hinge at each of two points spaced along its length, where pintleengaging curls from the two hinge leaves are omitted, is sleeved by one of two like coil'springs 111. The strip 1'! is cut away to provide a recess,

one thereof being indicated at 82, for each of said springs where the latter sleeves the pintle.

The spring is! seeniin Figs. 6 and '7 has at one end a straight offset portion 85 engaging an edge of thel-id 42 and at its .oppositeend a straight offset portion 85. A slant-bottomed lateral recess 85' in the bar .4! always receives the spring portion 84,; while a similar recess 86 receives the spring portion 83 when the ,lid is fully closed. The tension of the spring is such thatwere the lid 6 not present, the spring ,portion 83 would be forced to its position shownjin iFig. 6 or therebeyond.

The other spring .8l is similarly constituted, and the bar 4] has, .properly adjacent the lastnamed spring .8], recesses similar in form and .function to the recesses '82, and '86.

.As shown best in Fig. 7 a headed screw '31 is threaded into .a tapped hole "through the bar t! opposite the recess 85;, for entry into that recess to engage the portion 84 of the spring there shown. Spiral advance of said screw may 'from time to time be effected, to increase the tension of said spring, so that always, at the instant already explained, the lid will be snapped up to the position 42 of Fig. 4,. A'similar tension adjustment for the other spring is also provided, the adjusting screw thereof being seen .a't'BB inFig. '3.

All parts of the receptor are desirably made of metal, and to minimize elastic fatiguing of the springs 81, the lid 42 of the receptor andt-he lid carried bars '45 are preferably made of aluminum or analuminum alloy. When theplate 38 of the receptor, and its bars 40, ll and. 43 are also .made of aluminum or an aluminum alloy, this is advantageous also, as thereby a light weight and easily movable receptor is provided and one the treadle operation of which is not tiring on the attendant.

The, attendant will be under instruction always to close the lid '42 for being caught by the latchmember 45, before applying a forward footthrust to the treadle "59. 'Should the attendant forget, or be careless, the lid will be automatically closed by thrust thereagainst of the front edge of the ,roof wall of the housing 5!, substantially simultaneously with the initiation of a travel of jthereceptor toward full entry into the housing.
