- the top surface of the support '29 lies in a planesubstantiallycoincidentwith the'upper edgeofadie 31, which asshown in Fig. 5, is made up 'Ofseparatefmnt, rearand end'elements so that indi- .vidualcomponents-thereofmay be replaced when necessary because of localized wear or in order to change the shape of the die.
- a shoe plate 32 rests on the bed plate :11 andprovidesamountingfor. the die 31 whichhas a central opening 33.
- Fig. :2tthechute v137' extends. downwardlyiand forwardly inzthemachine, terminating in a tray '3 (Fig. '1) at th frontzthereof.
- the die opening 33 is shaped to conform to the outline of a business machine card and receives a correspondingly shaped punch 39 in opposed overlying relation to the die 31.
- the punch 39 is rigidly connected by bolts 41 (Fig. 8) to a punch holder 42, the punch being in etfcct a part of the holder 42 which i in spaced parallel relation to the shoe plate 32 and the bed plate 11.
- the holder 42 has attached thereto four corner posts 43 which extend downwardly through bushings 44 installed in registering openings in the plates 32 and 11.
- the inner or lower ends of the posts are each pivotally connected to a respective lever 45.
- Each lever 45 as shown in Fig. 6, is pivotally mounted at its mid point on a stud 46, the levers being arranged in opposed pairs adjacent to each. side of the machine.
- On each side of the machine is a side plate 47 each mounting a pair of the studs 46.
- Each pair of levers 45 is pivotally connected at the outer ends thereof to respective posts 43 and at its inner ends to a common pin 48 carried by an arm 49.
- Each arm 49 has an opening in which is mounted an eccentric 51 fast on the shaft 21.
- the web 25 has imprinted forms 52 thereon representing the cards to be cut from the web.
- the forms are disposed longitudinally of the web, in spaced relation to one another. They are brought, in a manner to be described, successively to register with die opening 33. Upon each descent of the punch 39, therefore, from the position of Fig. 7 to the position of Fig. 8, a form or card 52 is cut from the web 25 and drops downward through openings 33 and 35-36 into chute 37.
- a plunger 53 (Fig. 7) slidably mounted in a bushing 54 in the bed plate 11.
- the upper end of the plunger 53 has an inclined and transversely elongated head 55 thereon (see Fig. and is received withinthe die opening 33 adjacent the back end thereof.
- the lower end of the plunger is pivotally connected to one end of a lever 56 mounted intermediate its ends on a bracket 57 fixed to the underside of the bed plate 11.
- One end of the lever 56 is connected to the plunger 53.
- a coil spring 59 interposed between the bushing 54 and a collar 61 on the plunger, urges the assembly of parts comprising plunger 53, and lever 56 in a direction to maintain the roller on lever 56 in contact with cam 58.
- cam 58 which rotates with the shaft 21 and eccentrics 51, is such that the plunger 53 is Withdrawn through the major portion of each revolution of shaft 21, the head 55 during this interval occupying the position shown in Fig. 8. As so positioned it is out of the path of travel of the punch 39 but yet is in position to tilt or deflect the cut card. As the punch 39 rises out of the die opening 33, the plunger 53 is permitted to follow, attaining the position of Fig. 7 wherein the head 55 thereon constrains the web 25 to pass over the die 31 without interference with the edges thereof.
- the web 25 has a continuous series of perforations 62 adjacent to each side margin thereof and outside the borders of the cards 52. Cooperative with each series of perforations 62 is a feed device 63 presenting radial pins 64, the devices 63 occupying spaced apart positions on a shaft 65 pivotally mounted in brackets 66 secured to the sides of a pressure member 67.
- the member 67 is dependent from the punch holder 42, being supported by bolts 68 (see Figs. 4 and 8) for limited reciprocable movement relatively thereto.
- Springs 69 are interposed between the member 67 and the holder 42 so as to yieldingly maintain the member 67 in its outward position for motion with the holder 42.
- the pressure member 67 contacts the raised flange 34 on die 31 at or at about the time punch 39 begins to enter the opening 33.
- the web 25, which is stretched across the die 31, is thereby positively arrested and held from movement during the card cutting operation.
- the pressure member 67 also provides a guide for the web in the form of spaced apart plates 71 and 72 (see Figs. 5 and 8) which are fastened to the underside of the member 67 at spaced points in front of and behind the flange 34 on die 31.
- the upper surfaces of the plates 71 and 72, or those facing the member 67 are recessed to accommodate the web 25 which thereby is guided and supported by the plates 71 and 72.
- the web 25 encounters the feeding devices 63, the pins 64 thereof engaging perforations 62 for positive advancement of the web in synchronism with rotation of the feeding devices.
- Pressure fingers 73 on the brackets 66 embrace the feeding pins 64 and hold the web in engagement therewith.
- a guide member 74 (Fig. 8) deflects the uncut remnant of the web to the rear of the machine as it leaves the feeding devices 63.
- the shaft 65 on which the feeding devices 63 are mounted, is connected through a universal joint 75 to a stub shaft 76 extending into a housing 77 at one side of the machine. Also extending into housing 77, through the side plate 47, is the drive shaft 21 to the outer end of which is fixed a gear 78. A hearing 79 on the shaft 21, and a rib 81 integral with side plate 47, support a mounting plate 82.
- the stub shaft 76 is journaled in the mounting plate 82 and has secured thereto a gear 83, driven by the gear 78 through intermediate gears 84, 85, 86 and 87, all mounted in the plate 82.
- the toothed area of the gear 78 extends over only a part of its periphery. Accordingly, while rotation of the shaft 21 and gear 78 is continuous with operation of the motor 19, the transmission of a driving force through the gear train 83-87, shaft 76, and joint 75 to the shaft 65 is interrupted during a part of each revolution of the shaft 21. It will be understood that the construction and arrangement of parts is such that ,the gear 78 loses meshing engagement with gear 87 just prior to the moment the punch 39 enters die opening 33, and that such meshing engagement is resumed just after the punch leaves die opening 33.
- the duration of meshing engagement of the gear 78 with the gear 87 is predetermined to produce a travel of the web 25 just sufficient to move the previously cut portion of the web out of registry with the die 31 and to bring the next succeeding imprinted form 52 into registry with the die.
- the feeding devices 63 may be rotated by hand, through a knob 88 on the shaft 76, to place the web in the desired starting position.
- a side cover 89 (Fig. 5) on the machine has a reinforcing plate 91 secured thereto.
- Installed in the assembly comprising the cover and plate is a bearing 92 mounting a stub shaft 93.
- An arm 94 is secured to the shaft 93, on the inside of cover 89, and has pivotally mounted thereon a pawl 95 (see also Fig. 2).
- One end of the pawl 95 is presented in cooperative relation with the gear 23 on the end of the drive shaft 22.
- the other end of the pawl engages a pin 96 projecting laterally from the plate 91 through the cover 89, such other end having an inclined surface 97 in contact with the pin 96.
- a spring 98 urges the pawl 95 in a counterclockwise direction (Fig. 2) or in a direction to engage it with the gear 23. In the normal position of the parts, however, the pawl is held by the pin 96 in the disengaged position of Fig. 2 so as not to interfere with operation of the gear 23 by the motor 19.
- the pawl 95 is carried bodily therewith and at the same time is allowed to rock about its pivot on the arm 94 to engage the gear 23 (see Fig. 7).
- An oscillating motion of the arm 94 thus will produce a step by step rotary movement of the gear 23 and parts driven thereby.
- the described oscillatory motion of the arm 94 is effected by a hand crank 99 secured to the shaft 93 outside the cover 89.
- the crank normally is held against movement by a resilient seat 101 defined by a leaf spring 102 mounted on a plate 103 on the cover 89.
- the drive shaft 21 rotates continuously with operation of the motor 19.
- the punch holder 42- continuously reciprocates relatively to the die 31 and the feeding devices 63 are intermittently actuated to bring successive cards 52 in the web 25 to registry with the die 31.
- the presser member 67 is effective to arrest and hold down the web during the cutting operation, while the plunger 53 deflects the cut card into the chute 37 and prevents entanglement of the web with the edges of the die.
- a strip feeding device including guide means for con- 'tinuous web of paper material, said Web containing imprinted forms, die and punch elements in opposed relation, said die presenting a central opening and said punch being reciprocable into and out of said opening, feeding means for advancing the web between said die and punch elements, said elements acting to cut successive forms from said web, a chute beneath said die through which the out forms descend, a plunger reciprocable in said chute and through the opening in said die to tilt the out forms for passage through the chute and to raise the uncut portion of the web for continued movement beyond the die and punch, and means for operating said die, said feeding means and said plunger in timed relation to one another, so that the top of the plunger is below the lowermost portion of the punch during the descent of the punch and is raised upwardly to follow the punch to the level of the top of the die on the upstroke of the punch.

2,777,516 Patented Jan. 15, 1957 in view as will moreffullyappear in the specification, the
invention intendedto' be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, as herein- .a'fter described or illustrated in the accompanying drawings, or their equivalents.
Referring to the accompanying drawing, wherein is found the preferred but obviously .not necessarily the only form of embodiment ofthe invention,

Fig. '7-is a view similar to-Fig. 6 but showing the parts ina reverse position of operation; and
Fig. 8 is aside view taken outside the main framing of the-machine, partly brokenaway'to shown a longitudinal'sectionthrough theipunch and die mechanism.
Referring to the drawings, according-to the illustrative-embodiment of the invention, the strip feeding dc- -vice-is embodied in a'unitary machine notconnected in any larger machine orsystem.
'As shown in Fig. 2, it comprises a bed plate llresting on -blocks "12'which are in turn mounted on stanchions or legs 13.
:andatLtheir tops :to :the legs 13. The rear of the machine (seenalso Figs. -4.and 9) is reinforced by cross bracest'lfl connected at their upper ends to the blocks '12 sand; atltheir lower. ends to rearanglepiece 14. Spanning -With the -above primary and other incidentaleobiects 1 another gear '24 on shaft 21.
.The machine acts upon-a continuous web of. paper materialZS (Figs. 1 andS) drawnfromsa pack 26 supportedby away- 27 on the frontof themachine. From the tray -'27 a paper. guide 28 (Fig..8) extendsa upwardly and rearwardly,.terminating at a support .29 mounted on thezbed .plate 11. The top surface of the support '29 lies in a planesubstantiallycoincidentwith the'upper edgeofadie 31, which asshown in Fig. 5, is made up 'Ofseparatefmnt, rearand end'elements so that indi- .vidualcomponents-thereofmay be replaced when necessary because of localized wear or in order to change the shape of the die. A shoe plate 32 rests on the bed plate :11 andprovidesamountingfor. the die 31 whichhas a central opening 33. The side-walls of the opening 33 are slightly undercut while-around the rim of such openingthe=die31 is formed with an upturned .flange34. Openings 35 and 36 in the-shoeplate 32 and bed plate 11, respectively, lie beneath the die. opening -33 and provide forncommunicationtherewith of. a chute 37. As shown in Fig. :2tthechute v137' extends. downwardlyiand forwardly inzthemachine, terminating in a tray '3 (Fig. '1) at th frontzthereof.
The die opening 33 is shaped to conform to the outline of a business machine card and receives a correspondingly shaped punch 39 in opposed overlying relation to the die 31. The punch 39 is rigidly connected by bolts 41 (Fig. 8) to a punch holder 42, the punch being in etfcct a part of the holder 42 which i in spaced parallel relation to the shoe plate 32 and the bed plate 11.
The holder 42 has attached thereto four corner posts 43 which extend downwardly through bushings 44 installed in registering openings in the plates 32 and 11. The inner or lower ends of the posts are each pivotally connected to a respective lever 45. Each lever 45, as shown in Fig. 6, is pivotally mounted at its mid point on a stud 46, the levers being arranged in opposed pairs adjacent to each. side of the machine. On each side of the machine is a side plate 47 each mounting a pair of the studs 46. Each pair of levers 45 is pivotally connected at the outer ends thereof to respective posts 43 and at its inner ends to a common pin 48 carried by an arm 49. Each arm 49 has an opening in which is mounted an eccentric 51 fast on the shaft 21. Rotation of the shaft 21, therefore, serves to oscillate the levers 45 which in turn imparts a reciprocating motion to the posts 43 and to the holder 42 and its punch 39, carried thereby. The extremes of motion of the punch 39, under this movement, are substantially as indicated in Figs. 7 and 8.
The web 25 has imprinted forms 52 thereon representing the cards to be cut from the web. The forms are disposed longitudinally of the web, in spaced relation to one another. They are brought, in a manner to be described, successively to register with die opening 33. Upon each descent of the punch 39, therefore, from the position of Fig. 7 to the position of Fig. 8, a form or card 52 is cut from the web 25 and drops downward through openings 33 and 35-36 into chute 37.
In order to tilt the cards for endwise sliding motion down the chute 37, and in order to preclude inisoperation resulting from entanglement of the frame work of the web with the edge of the die, there is provided a plunger 53 (Fig. 7) slidably mounted in a bushing 54 in the bed plate 11. The upper end of the plunger 53 has an inclined and transversely elongated head 55 thereon (see Fig. and is received withinthe die opening 33 adjacent the back end thereof. The lower end of the plunger is pivotally connected to one end of a lever 56 mounted intermediate its ends on a bracket 57 fixed to the underside of the bed plate 11. One end of the lever 56 is connected to the plunger 53. The other end thereof carries a roller riding the periphery of a cam 58 secured to shaft 21. A coil spring 59, interposed between the bushing 54 and a collar 61 on the plunger, urges the assembly of parts comprising plunger 53, and lever 56 in a direction to maintain the roller on lever 56 in contact with cam 58.
The construction and arrangement of cam 58, which rotates with the shaft 21 and eccentrics 51, is such that the plunger 53 is Withdrawn through the major portion of each revolution of shaft 21, the head 55 during this interval occupying the position shown in Fig. 8. As so positioned it is out of the path of travel of the punch 39 but yet is in position to tilt or deflect the cut card. As the punch 39 rises out of the die opening 33, the plunger 53 is permitted to follow, attaining the position of Fig. 7 wherein the head 55 thereon constrains the web 25 to pass over the die 31 without interference with the edges thereof.
The web 25 has a continuous series of perforations 62 adjacent to each side margin thereof and outside the borders of the cards 52. Cooperative with each series of perforations 62 is a feed device 63 presenting radial pins 64, the devices 63 occupying spaced apart positions on a shaft 65 pivotally mounted in brackets 66 secured to the sides of a pressure member 67. The member 67 is dependent from the punch holder 42, being supported by bolts 68 (see Figs. 4 and 8) for limited reciprocable movement relatively thereto. Springs 69 are interposed between the member 67 and the holder 42 so as to yieldingly maintain the member 67 in its outward position for motion with the holder 42.
in the descent of the punch holder 42, the pressure member 67 contacts the raised flange 34 on die 31 at or at about the time punch 39 begins to enter the opening 33. The web 25, which is stretched across the die 31, is thereby positively arrested and held from movement during the card cutting operation.
The pressure member 67 also provides a guide for the web in the form of spaced apart plates 71 and 72 (see Figs. 5 and 8) which are fastened to the underside of the member 67 at spaced points in front of and behind the flange 34 on die 31. The upper surfaces of the plates 71 and 72, or those facing the member 67 are recessed to accommodate the web 25 which thereby is guided and supported by the plates 71 and 72.
Beyond the rear plate 72, the web 25 encounters the feeding devices 63, the pins 64 thereof engaging perforations 62 for positive advancement of the web in synchronism with rotation of the feeding devices. Pressure fingers 73 on the brackets 66 embrace the feeding pins 64 and hold the web in engagement therewith. A guide member 74 (Fig. 8) deflects the uncut remnant of the web to the rear of the machine as it leaves the feeding devices 63.
The shaft 65, on which the feeding devices 63 are mounted, is connected through a universal joint 75 to a stub shaft 76 extending into a housing 77 at one side of the machine. Also extending into housing 77, through the side plate 47, is the drive shaft 21 to the outer end of which is fixed a gear 78. A hearing 79 on the shaft 21, and a rib 81 integral with side plate 47, support a mounting plate 82. The stub shaft 76 is journaled in the mounting plate 82 and has secured thereto a gear 83, driven by the gear 78 through intermediate gears 84, 85, 86 and 87, all mounted in the plate 82.
As seen in Fig. 8, the toothed area of the gear 78 extends over only a part of its periphery. Accordingly, while rotation of the shaft 21 and gear 78 is continuous with operation of the motor 19, the transmission of a driving force through the gear train 83-87, shaft 76, and joint 75 to the shaft 65 is interrupted during a part of each revolution of the shaft 21. It will be understood that the construction and arrangement of parts is such that ,the gear 78 loses meshing engagement with gear 87 just prior to the moment the punch 39 enters die opening 33, and that such meshing engagement is resumed just after the punch leaves die opening 33. It will further be understood that the duration of meshing engagement of the gear 78 with the gear 87 is predetermined to produce a travel of the web 25 just sufficient to move the previously cut portion of the web out of registry with the die 31 and to bring the next succeeding imprinted form 52 into registry with the die.
In loading the machine, the feeding devices 63 may be rotated by hand, through a knob 88 on the shaft 76, to place the web in the desired starting position.
In further regard to loading of the machine, when the supply pack 26 is depleted and the motor 19 stopped, the position of the punch 39 relative to the die 31 may make it difiicult or impossible to insert the leading end of a new web. Accordingly, means are provided for manually moving the punch holder 42. Thus, a side cover 89 (Fig. 5) on the machine has a reinforcing plate 91 secured thereto. Installed in the assembly comprising the cover and plate is a bearing 92 mounting a stub shaft 93. An arm 94 is secured to the shaft 93, on the inside of cover 89, and has pivotally mounted thereon a pawl 95 (see also Fig. 2). One end of the pawl 95 is presented in cooperative relation with the gear 23 on the end of the drive shaft 22. The other end of the pawl engages a pin 96 projecting laterally from the plate 91 through the cover 89, such other end having an inclined surface 97 in contact with the pin 96. A spring 98 urges the pawl 95 in a counterclockwise direction (Fig. 2) or in a direction to engage it with the gear 23. In the normal position of the parts, however, the pawl is held by the pin 96 in the disengaged position of Fig. 2 so as not to interfere with operation of the gear 23 by the motor 19. Should the arm 94 be moved downward, or in a counterclockwise direction, the pawl 95 is carried bodily therewith and at the same time is allowed to rock about its pivot on the arm 94 to engage the gear 23 (see Fig. 7). An oscillating motion of the arm 94 thus will produce a step by step rotary movement of the gear 23 and parts driven thereby. The described oscillatory motion of the arm 94 is effected by a hand crank 99 secured to the shaft 93 outside the cover 89. The crank normally is held against movement by a resilient seat 101 defined by a leaf spring 102 mounted on a plate 103 on the cover 89.
The operation of the machine will be largely selfevident from the preceding discussion. The drive shaft 21 rotates continuously with operation of the motor 19. In response thereto the punch holder 42- continuously reciprocates relatively to the die 31 and the feeding devices 63 are intermittently actuated to bring successive cards 52 in the web 25 to registry with the die 31. The presser member 67 is effective to arrest and hold down the web during the cutting operation, while the plunger 53 deflects the cut card into the chute 37 and prevents entanglement of the web with the edges of the die.
From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into eifect.
Having thus described my invention, I claim: A strip feeding device, including guide means for con- 'tinuous web of paper material, said Web containing imprinted forms, die and punch elements in opposed relation, said die presenting a central opening and said punch being reciprocable into and out of said opening, feeding means for advancing the web between said die and punch elements, said elements acting to cut successive forms from said web, a chute beneath said die through which the out forms descend, a plunger reciprocable in said chute and through the opening in said die to tilt the out forms for passage through the chute and to raise the uncut portion of the web for continued movement beyond the die and punch, and means for operating said die, said feeding means and said plunger in timed relation to one another, so that the top of the plunger is below the lowermost portion of the punch during the descent of the punch and is raised upwardly to follow the punch to the level of the top of the die on the upstroke of the punch.
