It may be stated here that the device Q is equipped with a strip-lifting arm 9 which has an upturned extremity 9a adapted to work through a perforation 10 in the bottom of the side-delivery chute P. The function of this device is to lift the copy-strips sufciently away from the bottom of the chute P to enable them to be readily grasped by the operator preparatory to tearing the copyslips from they stri s by means of engagement gith a straight e ge. Reference is made to he casing A referably is made from sheet aluminum, or ot er sheet-metal. It is shown as comprising side walls 11 and removable end walls 12 and 13. At the front end of the compartment A (Fig. 2) is a removably secured transverse wall 14 which is disposed 'ust back of the lateral delivery-chute P.

ithin the compartment A is a roll-supporting device comprising side-plates 15 and cross-rods 15a. This forms a removable frame which can be withdrawn from the casing after the removal of the rear end 12. tween the lower portions of the plates 15 are secured inclined bottom plates 15". The original supply-roll 16 rests upon the rearmost bottom plate 15b and against a pair of the cross-rods 15, and the original paper strip 16a extends from the roll through the device B and thence over the platen.

The copy-strip rolls 17 rest upon the other inclined bottom plates 15b and the copystrips 17a extend therefrom through the device B and across the platen. 'It will be noted that the front roll 17 bears against the cross-wall 14 and the intermediate roll bears against a pair of the cross-rods 15a.

As mostclearly shown in Fig. 6, the platen B is in the form of a sheet-metal plate which has one lateral edge connected by means of a hinge 18 with the upper portion of one of the side walls of the casing.

The side wall of the casing is equipped below the hinge 18 with an open top receptacle 19 which contains the carbon strip roll 20. The carbon strips 20a extend transversely across the platen and are interleaved with the paper strips.

The cover-plate C has one lateral edgeportion extending over the receptacle 19 and connected to the upper outer portion of said receptacle by a hinge 21. The metal of the cover-plate C is struck or bevelled downwardly adjacent the opening C', thus providing a bevelled margin 22 for the opening. The cover-plate is shown equipped at its lower side with short posts 23 whose lower ends bear on the carbon strips and press them against the lateral margins of the platen, so that the carbons will be properly held against movement when the paper strips are fed therethrough.

The cover-plate C is equipped with a latch 24 which engages a slot with which the end wall 12 is provided.

The device B (Figs. 2, 4 and 5) is pivotally connect-ed with the rear end of the platen. The device B comprises a U-shaped framemember 25 whose forwardly extending arms are connected by means of a pintle 26 to lugs 27 which depend from the rear corners of the platen; and a series of guide-rolls 28` mounted in the U-shaped frame-member In the f with bores 30 which receive slidableplugs 31 which space the rolls 28. Between thefront plugs 31 and the end-portions of the pintle 26 are confined coil-springs32 which yieldinglyk hold the rolls in the position indicated in Fig. 5. The frame -has its arms provided with extensions S25a which extend beneath the rear portion of the platen and afford stops. The connections are such Vthat when thek platen is swung upwardly about the pivot 18, the device B will be lifted with the platen. On the other hand, when theplaten is in the horizontal position, the device Bmay be swung up-V wardly about the pintle 26, if desired.

The side walls '11 of the casing are provided (Fig. 5) with inwardly extending studs 33 which afford supports for the rear portion yof the device B. straightener-bar 34 which has rearwardly and lupwardly extending arms is pivotally connected withY the pins 33, and is adapted to be supported on studs 35 which'extend inwardly from the side walls 11. The web of the member 34 is adapted to engage the original paper strip 16a just below the rear guideroll Q8. The paper has a tendency to curve as it comes from the roll 1G, and theV purpose of the device 34 is to give it a reversecurve about the small diameter guide-roll, as shown. The rolls 17 are located suiiiciently forward to cause the copy-strips to be given reversecurves about the guide-rolls 28.

As appears inFig. 4, the cover-plate@ is equipped with short studs 36 adapted to bear on the frame 25 and hold the device B in the operative position.

in the filing compartment A2, a spacingmember 37 is applied to thev inner surfaceof one of the side walls (Fig. 1) and at the opposite side (Figs. 1 and y17), a gear housing plate 38 is secured to the innerV side of the casing-wall. The plate 38 is secured by means of screws 33n to tapped studs 33b which are riveted to the side wall ofthel casing.

The lower feed-roll D is journalled in bea-rings 39 (Fig. 7) which are secured to the side walls 11 above Ythe delivery-chute P. The feed-rollrE, as has been stated, is jour-y nalled ina supporting-member YE which is adapted to be swung upwardly about the pivot1.- 1t will be noted that'the pivot 1 is positioned to prevent the teeth of the gears 2 and 3 from vdisengaging when kthe supporting member E is swunfr u wardl Such an ar-` rangement prevents the rolls from getting out of their timed relation. At the opposite end, the member E is equipped with aspring pressed latch 40 which is pivotally connected to the member by means of apin 40a. r1`he latch is adaptedto engagea lug 41v with whichthe side wall 11 is kprovided.

The rolls D and E are provided with normal feed-disks` 42 and 43, respectively. These disks'are adapted to rotate idly when they encounter perforations44in the strips.

A U-shaped ly, these segments having radii correspondy ingwith the radii of the disks 42 and 43, re-y spectively. These segments are adapted to come into gripping relation at the conclusion of a cycle of operations, so as to hold the stripsgripped while the copy-slips are being torn from the strips. This position is shown in Fig. 9, and it will be understood that the segments are in position to initiate the feed of the strips when a new cycle of operations is begun. Afterthe perforations 44 are car# ried beyond the normal feed- disks 42 and 43, the normal feeding of the strips is accomplishedby said feed-disks. The member E is shown provided with slotted bearings 45 which receive the shaft of the upperfeed-roll, the shaft being sup* ported by means of pins 46. At the bearings, the memberv E is equipped with springs 4'? which tend to depress the feed-roll E.

The crank-shaft F (Fig. 1) extends across i the upper portion of the filing compartment the gear F2 which actuates the idler gear Gr` 'A (Figs. 7, 11 and 13). As shown, the pinion H which actuates the lower feed-roll is driven by the gear G.. c

.The gear G isy journalled on a stub-shaft 49 which has one Vend extending through the adjacent side wall 11 and secured thereto by riveting, as indicated at 49a in Fig. 13. The other end ofthe shaft 49 is supported ina perforation with which a'castmetal housing `plate 50 is provided. This plate is secured to the side wall` 11 and forms therewith a housing for the gears located at this part of the machine. c

The forked cam-actuated lever I is mounted on the pivot 4. It has'one arm 51 which engages a. cam'52 of the member G, and hasV another arm Y51a which is adapted to be en'- gaged by a stud, or roller, 53 with which the member G is equipped.; The member Ghas also formed integrally'therewith a cam 54 which is adaptedfto actuate the lever V.

The arm 55 of the lever I is kbent and works through a perforation 55 in the side wall 11; and, as appears from Fig. 12, the arm 55 is pivotally connected with the lower end iis ies

ter-blade L2. The clamping-members L and L are provided, respectively, with reduced extensions 61 and 62 which are adapted to bear upon the upper end-surfaces of the links .5 K; and the lugs, or extensions, 61 and 62 are connected by means of coil-springs 63 (Fig. 1) with studs 64 with which the side walls of the casing are equipped. Thus, when the knife is lowered to sever the original strip, the clamping-members L and L will be lowered upon the strips in advance of the severing operation. Thereupon, the knife will continue the downward movement.

Upon the return stroke7 after the knife has 1Q been withdrawn from the paper, the upper ends of the links K will encounter the projections 61 and 62 and the knife and clamping-members will complete the upstroke together.

The divider M is shown in Figs. 14 and 15. It comprises a cross-bar 65 which is secured at its ends to the side walls of the casing. It has a rearwardly presented tapering portion 66 which is adapted to separate the lower strips (copy-strips) 17 from the upper or original strip 16. The divider is provided with a flat upper surface and has a steel inset shearing-bar 67. Adjacent the shearingedge is a vertical slot 68 through which bits of paper can drop. The slot 68 is disposed immediately beneath the cutter-blade L2.

The member 65 is equipped with depending lugs 69 to which the upper portion of the front wall of the delivery-chute P is secured by means of screws 70. A strip-lifting device 71 is pivotally connected with the apex portion of the cross-bar 65. The member 71 consists of a strip of sheet-metal which is bent in triangular form, providing an upper wing 71 and a lower wing 71. The apex portion is engaged by a pintle 72 while the wings embrace the upper and lower surfaces of the triangular portion of the bar 65. A small coil-spring 73 tends to lift the upper wing so that the advance edge of the original er strip 16 will cross the slot 68 without culty in the feeding operation. The lower wing is adaptedy to project across the lower end of the slot 68, so that the copystrips will be guided across the slot without difficulty. The pintle 72 is held in position by clips 74 (Fig. 12).

As shown in ig. 14, a bar 75 extends across the upper portion of the casing immediately back of the platen and forms a support for the strips of paper just below the meeting plane of the feed-rolls. The bar 75 is properly slotted to accommodate the lower feeddisks, the register-ngers, and the lower feedsegments. The bar is provided with a tearing edge 75 disposed just hack of the lower feed-roll on which the copy-slipsy may be severed from the lower strips of paper. It will be noted that the divider M and the bar Q 75 together form a throat, adording a paspa di Leonizo sage 76 through which the copy-strips are kdeflected downwardly into the chute P, by which they are given a curl and diverted laterally to make the corner portions of the strip readily accessible at the large end of the chute P, which chute extends through an opening 77 (Fig. 1) in the side wall 11 of the casing.

As will be understood by reference to Figs. 1, 12 and 14, the side walls 11 of the casing are equipped at their inner sides with standards 78 which may, if desired, be cast integrally with the divider-bar 65, or which ma be separately attached to the side walls, i desired. The clips 74 are secured to the upper ends of the standards, or posts, 78 by means of screws 79; and the clips have depending members 74 which are spaced back of the posts 78 ina manner to form guides for the clamping-members L and L and the interposed cutter-blade L2. As appears from Fig. 12, the members 74 have offset lower end-portions which engage the ends of the pintle 72 upon which the combination guard and paper-lifter 71 is pivoted.

The divider-bar 65 has a. bevelled front portion 80 above which is located the guide, or delector, N, whose base-portion 81 is secured to the lower end-portions of the posts 78.

The delivery-chute P (Figs. 7, 11, 12 and 19) is preferably formed of sheet-metal. It has a. small end 82 secured to one of the side walls 11 and a large end 83 which extends through the lateral opening 77 of the other side wall. The lower wall of the chute is inclined, as appears from Fig. 19, and the chute flares from its small end to the large end, so that as the copy-strips are deflected downwardly by the divider, they will be curled and diverted laterally, as suggested above. s,

The flin device Q (Figs. 11 and 18) comprises a roc -shaft 84 journalled in the lower portion of the tiling compartment and equipped with a pair of filing-pins 84 which arek curved rearwardlyat their upper portions. As previously explained, the shaft 84 is equipped with an arm 8 through the medium of which the impaling-pins 84 are retracted in the manner illustrated in Fig. 11. The impaling-pins are permitted to move towards the divider M at the proper time to cause the pins to enter the punchholes of the 'strip 16 after the advance end of the strip has been curled downwardly by the deflector N. This will be understood from Fig. 15, from which it will be understood also that after the impaling-pins engage the punch-holes, the advance end of the strip 16 is guided downwardly by the pins while the feeding of the strip continues.

The device R kcomprises a rock-shaft 85 journalled in the lower portion of the filing compartment just back of the impaling device; arms 86 extending upwardly from the rock-shaft adjacent the opposite sides of the casing and equipped with inturned extremities 86a adapted to engage the strip in the manner shown in Fig. 18; and an arm 87 projecting forwardly from the rock-shaft and actuated through the medium of the cam-actuated slide U3.

As appears from Fig. 17, the rockshaft 811 is equipped with a spring 845 for actuating in one direction; and the rockshaft is equipped witha spring 85a for `actuating it in one direction.

As appears from Figs. 10 and 14, the register-ngers S which normally bear against the lower side of the lowermost strip of paper are yieldingly held in such position by a light spring 88 whichis attached to the casing and yto a short arm 89 with which the rock-shaftSis equipped. At about the end of the feeding operation, the register-fingers enter the punch-holes 44. Normally this will occur just before the initial feed-segments grip the strips and while the normal feed-disks engage the punch-holes and thus work idly. This gives the strips opportunity for adjustment, or proper registration, it being understood that the guide-rolls 28 tend somewhat to retract the strips.

As appears from Fig. 14,the lever S2 is adapted to retract the register-fingers.. This action is accomplished through the medium of the rod S4, which, as shown in Fig. 17 connects with thearm S5 of the register-nnger lever S7. ConsideringFigs. 1, 16 and 17, it will be noted that the crank latchingmember T has a tubular pivot portion 90 pivoted on the shaft S5 of the register-finger actuating-lever, and has a bevelled notched latching portion 91 adapted to engage a portion 92 with which thecrank-arm F is equipped.

The arm S7 is equipped kwith a'stud 93 which works in a short slot 94CV with which the arm of the latch-member T is provided. The lever S7 and the latch-member T normally are held in the position shown in Fig.

17 by the rod S4 which is acted upon by the spring 6 shown Fig. 14.

This is the position 1n which ythe cranky shaft is latched at the end of a cycle of operations. In this position, the arm S5 is engaged by the free end of an auxiliary latching-lever 96 which is supported by a pivot 97 connectedwith the side wall 11. The arm S5 is also provided with a shoulder 98 which is adapted to be engaged by the notch of the latching-member 96 when the lever S7r and the crank-latch T are moved to re-y lease the crank. A spring 99 tends to draw the device 96 downwardly.

The crank-latch T is provided with a short arm 100 whichis equipped with a pin 101 which works through a slot 102 in the side wall 11 of the casing. The inner end of the stud 101 has connected therewith a spring 103 which tends to hold the crank-latch in the position shown in Fig. 17. "When the crank is released, the auxiliary latch 96 drops so that the lug 101 thereof will rest upon a lever 105 which is connected by a pivot 106 to the side wall 11. In the operation of the cranka cam 107 formed integrally with the gear U serves to depress the end 105a and thereby restore the member 96 to its first position. At these-me rtime,the lever 105 lifts the pin 101 and thus holds the crank-latch out of the way until near the end ofthe cycle of operations, when the crank-latch is pervmittedfto return to normal position so as to be ready to engage and latch the crank.V

Before starting the cycle of operations, it is necessary to retract the lever S7 and thus draw the rod S4 to the right from the posi-y tion shown in Fig. 14 so as to causeA the lever S2 toy rock the shaft S and withdraw the registerfingers- Shortly after vthe cycleof operations has started, it is necessary to release the registerpins and permit them to bear against thelower side of the strips of paper; and this is accomplished through the medium of the cam 107 which causes thev lever 105 to lift the pawl, or latch, 96 so as to free it from engagement with the shoulder 98 of the lever S5. kIn the arrangement shown, however, the crank makes two revolutions in eachcycle of operations; hence, it is necessary to hold the crank-latch T out of thefwayl of the crank during passage of the crank; and this is accomplished by the lever 105 acting through the medium of the pin 101, which thus swings the crank-latch in timed relation to permit the crank to pass. Y

The tiling compartment A2 is adapted to be, closed by a closure 108 which is pivotally connected with the front end of the casing by pivots 109. The closure 108 is equipped with a lock 110 whose bolt is adapted to engage a slot 111 in the side wall 11.

The operation of the machine may be described briefly:

The register-pins 'S are normally in the position shown in Figs. 7 and 10 when the crank is in the latched position shown in Fig. 1. The gears 2 and 3 have a. gear ratio corresponding with the ratio of the normal feed-A disks. Thus, the upper feed-rool E is adapt-V ed to turn more rapidly than the lowerfeed-k roll D. In the illustration' given, they upper feed-roll ymakes seven turns while ,the lowerfeed-roll makes five turns during the cycle of operations. To accomplish this, theV crank makes two complete revolutions. The strips are initially passed over the platen and 1 the punch-holes 4A at the advance ends of the strips are brought intoengagement with the register-pins S The cover-plate()` is then lowered to and latched inthe horizontal position. i

In the illustration given', the crank makes one complete turn in the operation of feeding the strips'. This brings the next set of punch-holes 44 into registration with the normal feed-disks, whereupon these disks cease to effect feeding of the paper. During the next revolution of the crank-shaft, the feeddisks work idly, and during this time the clamping-members L and Lk and the cutterblade L2 are actuated; also, the device R is actuated, after the original strip 16al has been severed, to overturn the severed slip, and the filing-pins are then retracted so as to enable the next strip to be fed downwardly into position to be engaged by the filing-pins, when the filing-pins are again permitted to move to the impaling position. The copy-strips are defiected downwardly into and curled backwardly within the chute P and are diverted laterally by the chute, s'o that a corner portion projects through the lateral opening in the casing. The operator grasps the projecting corner of the copy-strips and by direct lateral pull severs the strips over the tearing-edge From Fig. 14, it will be noted that the rear damping-member L is disposed somewhat lower than the front clamping-member L. Thus` the rear clamping-member engages the strip in advance of thefront clamping-member; and after both clamping-members are seated, the knife operates to sever the paper. In the operation of lifting the clamps and knife, the blade is withdrawn, the front clamp starts to rise, and the rear clamp starts to rise an instant later.

To enable the crank to make a second revolution. the crank-latch T is held retracted through the medium of the pin 101 and the cam-actuated lever 105. Before the second 4revolution of the crank-shaft is completed, the crank-latch is permitted to return to normal position in readiness to engage and latch the crank.

The initial feed-segments 42 and 43a grip the strips at about the conclusion of the cycle of operations, so as to hold the strips firmly While the copy-strips are being severed and so as to be in readiness to initiate the feed of the stri s in the next cycle of operations.

Ordinarlly, the strips of paper are provided with printed forms and with punchholes near the advance ends of the forms. These punch-holes are encountered by the normal feed-disks at the conclusion of a feeding operation and are also engaged b y the register-fingers. In the next cycle of operations, ythe punch-holes of the original strip serve to receive the impaling-pins of the filing device, and the pins serve to guide the advance end of the strip downwardly and the strip is filed in the inverted position, or face downward.

While the machine illustrated is provided with a plurality of supply-rolls from which the strlps of paper are taken, certain features of the invention are not'limited to a machine employing separate supply-rolls. The stri s may be taken from any suitable supp y source.'

The machine described is simple and reliable, and is certain in operation. The feature of employing a register-finger releasing device and crank-latch closely associated therewith and adapted to be simultaneously actuated in the operation of releasing the crank constitutes a very important improvement from a practical standpoint; and the provision of means for holding the cranklatch in retracted position so that the crank can make a plurality of revolutions during the cycle of operations is a feature of practical importance. By gearing the crank-shaft to the feed-rolls in such manner that the feedrolls are caused to rotate more rapidly than the crank-shaft, it is possible to employ comparatively small feed-disks, and the shearing-edge 75 can be located a comparatively short distance from the point where the register-fingers engage the punch-holes, so that the copy-strips canbe severed close enough to the punch-holes to avoid excessive margins beyond the punch-holes.

It may be added that in Fig. 17 a pawl 112 is shown in engagement with the gear U on the crank-shaft, this pawl serving to preventretrograde movement of the crank, but per- Initting the crank-shaft to turn freely in the direction indicated by the arrow.

The foregoing detailed description has been given for clearness of understanding only and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.
