Referring now to the drawings, the machine may be housed in a casing or cabinet of y'any suitable size and configuration, and in the present instance the machine is provided with a base plate 20 supported upon feet 21 preferably in the form of suction cups of rubber or the like adapted to grip the supporting surface for the machine and maintain the machine against accidental shifting incident to its operation. The base plate 20 is provided with a pair `of spaced t apart side plates 22 suitably secured along the opposite longitudinal edge portions of the base plate 20 and which may be cut away or beveled toward their upper edges to one end of the .machine to adapt the enclosure or casing to the general configuration of the machin Dis d in the inner end of the casing is a ro strip support which comprises a air of spaced frame members- 23 of substantially angular formation arranged with vertical portions slidably bearing at their lower ends upon the base plate and with their horizontal ortions projecting forwardly between the si e plates 22. The frame members 23 are provided in their upper edges and adjacent the vertical portions thereof with downwardly and forwardly inclined slots onsockets 24 adapted to receive therein the opposite end portions of a cross shaft or pin 25 adapted to engage through the core or spool 26 of a roll 27 of strip paper or the like.
The pin 25 is retained in the frame members 23 by the imperforate side walls of the lates 22 while the frame members 23 may moved toward and from each other and the opposite sides of the roll 27 in order to accommodate rolls of paper strips of different widths.
Means is provided for adjusting the roll holder as to width, such means comprising, as best shown in Figure 3, a transverse screw shaft 28 having bearing at its opposite ends in the side plates 22 and which is provided on one end, and beyond the adjacent plate 22, with a suitably knuiled or milled thumb piece 29 fixed to the shaft and by means of which the shaft or screw 28 may be turned in either direction. The shaft or screw 28 has opposite screw threads at opposite ends and is provided with an intermediate disc 30 lying between the opposite threaded `,portions and adapted to limit the inward movement of traveling nuts 31 carried on the, screw 28 at opposite sides of the disc 30.
Each screw 31 is suitably secured to an adjacent frame member 23 so that as the traveling nuts 31 move toward and from each other the frame members 23 are carried therewith. In this manner by means of the external thumb piece 29 the desired tension may be placed upon the paper roll 27 and the aper strip may be properly ycentered wit respect to the mechanism in the casin Thframe members 23 are beveled or cut away at their forward sides or under ends to accommodate the forward portions of a pair of feed rolls 32 whichmay be of rubber or other suitable resilient material, and the forward beveled edges of the frame members 23 carry inwardly projecting lower tongues 33 which are disposed beneath a pair of upper tongues 34 which project inwardly from the up er edges of the frame members 23.
may be best seen 'from Figure 4, the feed rollers 32 are mounted upon a hollow shaft 35 provided with endwise projecting teeth 36 at one end which are of ratchet form and adapted to co-operate with a ratchet rthrough and whic wheel 37 slidably mounted upon an inner shaft 38 which has reduced trunnions at o'posite ends supported in the side plates 22.
he ratchet wheel 37 houses in its outer side a sprin 39 which bears against the hub of the rate et wheel 37 at one end 'and against a transverse pin 40 at its other end, the pin passin transversely through the shaft 38 and lying at opposite ends in slots 41 formed in the ratchet wheel 37. The ratchet wheel 37 is thus-locked by thef pin 40 to the shaft 38 to turn therewith but/is permitted an axial movement on the shaft under the influence of the spring 39 for normally tending to interlock the ratchet wheel 37 with the teeth 36 of the hollow shaft.
At the opposite end of the feed roller strueture the inner shaft 38 is provided with a pinion 42 which lies within an arcuate slot 43 of a sector 44, the slot 43 having rack teeth 45 in its upper edge which intermesh with the pinion 42 so as to turn the latter when the sector 44 is moved. The sector 44 is provided along its forward substantially radial edge with an in-turned stop flange 46 adapted to engage the pinion 42 when the sector is swung backwardly into its normal position of rest.
The sector 44 is mounted upon a shaft 47 which is the main shaft of the machine and which has bearing at opposite ends in the side plates 22. One end of the shaft 47 is provided with a handlever 48 which lies at the outer side of the adjacent side plate 22 and which extends forwardly from the shaft into a suitable position for engagement by the h and for depressing the lever 48. The sector 44 is provided with a returned hub portion 49 on its lower or inner end, the returned portion 49 providing with the sector 44 spaced bearing portions which are apertured for the reception of the shaft 47 therethrou h, as clearly shown in Figures 11 and 12. set screw 50 is carried through the lower end of the returned portion 49 and is ada ted to bind against the adjacent side of the ever 48 for correctly positioning the shaft and the lever 49 for convenient o eration.
A s ring arm 51 is rovide with a returne hub portion 52 w ich is suitably apertured for the rece tion of the shaft 47 thereis adjustably fixed to the shaft y a set screw 53 which, as shown in Figure 1 may be secured with the spring arm 51 extending rearwardly and upwardly horizontallyfrom the shaft 47. A main sprin 54 is anchored to the base plate 20 at one en and at its other end is secured to the outer end of the arm 51 for normally urging the latter downwardly and to normally maintain the operating lever 48 in a raised position as shown in dotted lines in Fi re 1.
The hub portion 52 of t e spring arm 51 is provided at one forward edge with a forwardly projecting lug 55 carrying a pivot 56 upon which is mounted a trip lever 57, the upper end of which is bent crosswise forengagement with the knife operating mechanismas will hereinafter appear. rlhe lower portion of the trip lever is ste pcd downwardly and backwardly to provi e a shoulder 58 adapted to seat beneath the sprin arm 51 and limit the swinging movement o the trip lever in one direction. The free lower end of the trip lever 57 is provided with a spring 59 which extends rearwardly andis suitably secured to the spring arm 51 for normally urging the shoulder 58 to its seat. l Disposed in a downwardlyjand backwardly inclined position between the side plates 22, and forwardly of the feed rollers 32, is a lmife or blade guide 60. As may be best seen from Figures 1, 14 and 15, this blade guide may be stamped from a single sheet of metal which is overturned upon itself to provide a lower closed end and which is suitably bent and ystamped .to provide a slot 61 in its bottom and a pair of'outwardly and oppositely turned wings 62 at the opposite sides of the blade or knife/guard, the wings 62 being suitabl apertured and threaded for the rece tion o screws and the like for securing t e wings against the inner opposite sides of the side plates 22.
The upper transverse edges of the knife guide 60 are also turned outwardly away from each other to provide flanges 63, and the side portions of the guide .62 may be provided with vertically extending and inwardly pressed projections 64, which as shown in Figure 15, approach each other, are disposed in opposite relation, and which provide therebetween a suitable space for the rece tion of a knife or cutter blade 65. The bla e 65 has bea-ring upon the projections 64 and is held thereby in proper position in the guide 62. As may best be seen from Figure 11, the knife 65 is provided in its upper edge and intermediate its ends with a cutting edge which converges downwardly to the central portion of the knife whereby to effect simultaneous and equal cutting of the strip from the outer edges inwardly thereof.
The lower end of the knife 65 is provided with a lug or projection 66 which projects down through the slot 61 and carries a screw 67 adapted for engagement in the upper end of a slide bar 68 which is turned over at its upper extremity to provide a flange 69 which passes through a slot 70 formed in the lower portion of the knife blade,` 65. The slide bar 68 extends downwardly through the sl'ot 61 in the knife guide 60 and is provided on its lower end with an enlarged loop 71 adapted to receive therein the upper portion of the trip lever 57 the top of the trip lever being arranged to engage the upper edge of the loop 71 for raising the slide bar and the knife blade 65.
The loop 1 is oset rearwardly from the body portion ,of the slide bar 68 as may be seen in Figures 1 and 13 so as to dis se' the loop 71 in the path of the trip lever 5 The lower end ofthe loop 71 is connected to a spring 72 which extends downwardly and is anchored to the base plate 20 for normally drawin knife bl the throat of the machine above the knife guide.
A throat or guide plate 73 bestl shown in Figures 7 and 8, is secured by means of screws 7 4 or the like to the up r sidel of the top flange 63 of theknife cated rearwardly of the ane of operation of the knife blade 65. e throat or 'de plate 73 'extends rearwardly from the 'fe guide toward the feed rollers 32 and the plate 3 is provided with a defiecting tongue' 75 intermediate its rear edge and ywhich rojects between the spaced apart feed ro 1ers 32 for insuring the picking up of the paper strip from the feed rollers 32 and directing the strip over the upper surface ofthe plate 73. A carrier plate 76 is secured by the screws 74to the upper side of the throat plate 73 and is spaced therefrom by 'rojections or spacers'77 which are carrie upony the upper side of the throat plate 73 and which are arranged toward the opposite ends` of the latter to provide a clear strip receiving throat or space between the plates 73 and 76. j
It iwill `be noted from Figure 5 that the carrier plate'76 is provided with elongated openings or slots for the screws 741so that the carrier plate may be adjusted lengthwise of the machine upon the throat plate 73 and with respect to the feed rollers 32. The carrier plate 76 is provided near its opposite ends and at -its rear edge with a pair of upwardly ,arched bearing tongues 78 pro-` viding downwardly opening bearings adapt ed to receive the opposite ends of a shaft 79 upon which are mounted suitable guide rollers 80 having milled or knurled peripheries for engagement with the upper surface of a strip paper through the throat of the machine. The shaft 79 is depressed toward the feed rollers 32 by means of a spring arm 81 suitably secured to the carrier plate 76 and which also co-operates with a spacing tongue 82 which projects rearwardly from the intergul e which is lo.
itself to provide an elongated loop of desired sise and with a lower wall which conforms in curvature substantially to that of the guide late 84, and which provides the upper wall o the guide slot for t e paper mit;
- is guard 86 is secured under the upper shoulders of the screws 85in a removable manner, apertures 86', formed throu h the ard, of correspondin diameter to t e hea of the screws are a apted to receive the latter, as shown in'Figure 17, said aper` tures are in communication with elongated restricted openings 86", the latter being of the size of the medial portion of the screws between the shoulders 85 and 85" thereof, thereby retain the guard .86 between the said shoulders. To remove the guard the latter is moved toward-the spool 26 until theapertures 86 are in alinement with the hea s of the screws;'whereupon the guard may be lifted u wardly and detached.
As will be noted from Figures 9 and 10 particularly, the intermediate portions of the late 84 and the guard 86`-are offset upwar y to provide an entrance throat 87 for the aper strip as it leaves the knife guard.
e moistener is located in the forward end of the casing beneath the guide plate 84 and is in the form of a removable receptacle 88 adapted to contain water or the like and in which is placed a rectangular perforated frame 89 havin an exterior covering of absorbent materia which ma be felt, flannel or the like, and which is a apted to raise the water from the receptacle 88 by ca illa -attraction or the like. The forward e e of the guide lplate 84 is adapted to yielding y bear upon t e upper side of the moistener element 90 and to thus carry the paper strip forwardly and downwardl into contact with the moistener element 90 or moistening the gummed lower surface of the strip.
In order to insure the evendistribution of moisture to the strip, the receptacle 88 may be provided at its forward portion and at opposite edges with a pair of upstanding guide flanges 91 having vertical slots l92 therein for receiving the opposite ends of a roller shaft 93 upon which is mounted a weighted roller 94. The roller 94 is disd, as shown particularly in Figure l. immediately in front of the guard 86 and above the paper strip so as to yieldingly urge the latter against the moistener.
The roller 94 is adapted to turn under the forward movement of the paper strip which is fed .forwardly by the inherent stiiness of the strip combined with the conning walls of the assa for the strip. It is a parent that w en e strip is severed the orward end thereof ma be grasped and drawn from beneath the ro er 94 so as to withdraw the strip as cut from the machine.
In ko ion, a paper strip roll 27 is inserted tween the frame members 23 after the shaft or `pin 25 has been placed through the hub or spool 26 of the roll. The ends of the shaft 25 are seated in the bottoms of the slots 2 4 and thus the aper roll 27 is supported in such position t at it may turn on the shaft 25 between the frame members 23. By adjusting the transverse screw 28 the frame members may be moved toward and from each other to the desired extent so as to center the strip from the roll 27 with res ect to the longitudinal way or throat of e machine.
As shown in Figure 1, the paper strip from the roll 27 is carr1ed over the traveling nuts 31 and the disc 30 of the frame ad'usting means and is thence carried forwardly between the tongues 33 and 34 to the feed rollers 32. The strip is held in frictional contact with the feed rollers 32 by the guide or pressure vrollers 80 and the strip is thus drawn from the roll 27 and rojected forwardly through the machine. llhe strip enters the throat of the machine between the tongues 75 and 82, passes between the throat plate 73 and the carrier plate 76 and then traverses the upper end of the knife guide 60.
The strip when fed forwardly by the rollers 32 passes across the knife guide 60 and into the throat 87 of the moistening device, the stri passin downwardly between the forwar guide ate 84 and the guide 86 into position beneat the wei hted roller 94.
In order to feed the strip forwardly in the machine the operatin lever 48 is de ressed to a position near its ower limit, and) if the vlength of strip projected from the machine is vnot suflicient, the lever 48 is permitted to rise under tension of the spring 54 so that the lever 48 may be reciprocated the desired number of times before it is depressed to its full extent. Each time the levei` 48 is depressed the shaft 47 is turned and the sector 48 is swung 4forwardly to carry the rack teeth 45 over the pinion 42 to turn the same. When the pinion 42 turns by. the forward movement of the sector, the spring 39 moves the ratchet wheel 37 into engagement with the teeth 36vso as to turn the feed rollers 34 and thus move the paper strip forwardly. When, however, the operating lever 48 is released, the main spring 54 turns l.the shaft 48 andthe sector 44 back into normal position, and during such movement the pmion 42 is turned in a reverse direction with the result that the ratchet teeth of the shaft 35 and the ratchet wheel 37 slide over one another and the spring 39 is suiciently weak to lli permit this operation without forcing the paper strip backwardly. Thus, the .paper strip is'intermittently fed in a forward directlon during the reciprocating movement of the operating lever 48.
When the desired length of paper strip is determined` and is in advance of the knife guide 60, the lever 48 is depressed to its full extent with-the result that the trip lever 57 is snap ed downwardly into the loop 71. When tge operating lever .48 is now released, the main sprin 54 turns the shaft 47, raises the trip lever 5 and the latter binds against the upper edge of the loop 71 as thek shoulder 58 is seated and thus the sEring .54 raises the slide bar 68 and the knife lade 65 u wardly to project the cutting edge of the ife 65 upwardly through the strip of paper to sever the same.
It will be noted that the main spring 54 is of greater size and resistance than the spring 72 for overcoming the latter, the spring 72 returning the knife blade 65 into its lowermost normal position after the trip signature.
. ALEXIS F. GILLET.
lever 57 has passed beyond the upper edge j of the loop 7l.
The projecting end of the strip is now grasped and drawn forwardly so as to remove the strip from the machine, the roller 94 insuring that the entire length of the strip passing from the forward end of the machine is brought in contact with the moistener element 90 so as to properly moisten the lower gummed surface of the strip.
By adjustment of the set screws connected with the shaft 47 it is apparent that the throw of the lever 48 and the operation of the feed rollers 32 may be adjusted or regulated and also that the desired tension and tripping of the knife or cutting' blade 65 may be had.
As above explained, the -roll support 'is also capable of adjustment as to width so as to accommodate strips of different widths and to insure the centering of the same with respect to the feed rollers 32 and the other parts of the machine.
It is obvious that various changes and modifications may be made in the details of construction and design of the above speeifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.
