This invention hasto do. with punching and is particularly directed to perforating a stack of paper, cardboard, leatheran'd/cr the :like and more specifically is concerned with a conveniently controlled and serviceable perforating machine having means selectively adaptable for severally and/or jointly actuating a plurality of slidably guided punching tools for readily penetrating the stack-of sheet-material. Oneimportant object of the invention resides in the provision of novel means for coupling or uncoupling the cutting tools to render them -severally or jointly effective or ineffective with-common driving means therefor. Another object ofthe invention is concerned with the utilization of a plurality of tool sustaining standards or headers conveniently and selectively adjustable longitudinally of the machine for desirably controlling the spacing of the cutting. or punching tools. Specifically the invention has as another object to'provide' serviceable and regulatory means for controlling the extent of insertion of a stacker" material into the headers prior to perforating. More particularly the invention has as a further object the utilization of a novel stop slidably' guided longitudinally of the machine forcontrolling: predetermined setting of the stack relative to the cutting tools of the headers priorto insertion of the stack in the headers. As a further object the invention is concerned Wtih slidably guided tool carrying headers which may be .quickly. 'attach'edLto the perforating machine and which if desired may be readily disengaged therefrom. Still a further. object of the invention deals with novel shaft means adapted to be threaded .into the'several headers toremovably interlock with the cutting tools thereof and adapted to be rotatably driven by a lever appropriately accessible at one side .of the machine. Further -.functional and: structural features'of the invention reside,1inter alia, in the provision of means for quickly arranging the operating lever in a loweredand out of the way position for purposes of compactly transporting the machine; the provision of means to permit withdrawal of the driven shaft means from the .headerspreparatory to the removal of the headers jointly and/or severally from the machine, the provision of. rotatable indiciacarrying means for. actuating reciprocablameans to limit the admission 'of'the stack of material into the headers.- Other functional, structural and salient features, advantages. and objects of theiinvention will appear from the teachings 'of'the'following detailed description considered in connection .Withthe accompanying drawings. wherein:

In the embodiment disclosed, the perforating machine is generally designated M and is characterized by a one piece and sturdy cast iron frame having spaced side or standards If! integrally merged with a rear strengthening'brace H and with the front strengthening brace l2 also integral with the standards l0. 1

Also integral with the transversely arranged standards is of the frame are the forwardly projecting ledges 13 on which the graduated panel M is secured by the screws 35. This panel has its top face substantially flush with the alined lower walls H5 or the stack receiving gaps G of the end brackets lo.

Interrupting the forwardly extending ledges I3 are the alined slots id in which rod l9 (Figs. '7, 7 and 7 is slidably and guided longitudinally by the spaced but adjacent margins and 2! of the rear graduated panel I4 and the front panel 22, the latter being secured by the adjustable and removable screws 23 (Fig. 1) fastened to the forwardly disposed portions 24 of the ledges I3.

Thus arranged the front and rear panels are separated by a gap 25 disposed lengthwise of the platform for supporting a stack of paper, cardboard and/or leather adapted to be perforated.

Referring again to the forward panel 22, the

latter is also desirably supported by the front corner blocks 26 which in turn are fixedly mounted on the cross bars 27 to which the spaced ears 28 of the spaced standards I0 are appropriatelyfastened and the downwardly turned front wall 25 of the front panel 22 is disposed adjacent the front ends of the spaced blocks 25.

Associated with the slidably and longitudinally guided rod i9 is the stop or clamping plate having a perforation 3i through which the threaded shank or stem 32 extends, the stem being threadably interconnected with the guide rod 29 by the threaded bore 33. Attached to and depending from the stop or gage 50 are the spaced posts 3 extending through correspondingly shaped openings 35 in the rod H3. tating head 35 of stem 32, rod l9 may be shifted towards or away from the margins 28 and 2! of the rear and front panels It and 22, to be clamped thereagainst or be unclamped therefrom. If unclamped, margins 2G and 2! characterize rails for slidably guiding the displacement of the rod [9 and by the arrangement disclosed, the stop or' gage 39 in its clamped relation against the panels is substantially normal to the dividing gap 25 as illustrated.

According to the invention a plurality of tool carrying headers generally denoted H is desirably interposed between the spaced standards ill. Specifically each of the headers H is slidably and removably mounted on the rotatable shaft S journaled in the openings or bearings 40 in the standards It and in the openings 5| in the several headers H each of which embodies a vertical bore 52 normal to and in communication with its bearing or opening 4!.

The perforating or punching tools generally denoted T are slidably guided in the vertical bores 52 and each include a punching stem 43 slidably guided in a vertical bore 44 in alinement with bore 45 in the anvil A of its respective header, the anvil defining with its header, a suitable gap or throat to permit the insertion of a stack of paper, cardboard, leather and/or the like therein. Each punching tool T is p ovided with an in- Thus by ro- H 1 termediately arranged reduced portion 47 from which laterally extends a tooth 48 normally disposed in an outwardly diverged gap or groove 49 running lengthwise of the operating 'or driven shaft S. By this arrangement upper and

lower lips

55 and 51 are provided on the operating S and these in fact movably interlock with the teeth 58 of the cutting tools T. To the ro 'tatable shaft S is desirably fastened the operating handle 52 which includes a lug 53 for coop erating with a boss 54 extending from a standard ill to limit the downward rotational stroke of the handle (Fig. 2) at which time the punching stems 43 of the tools as T (Fig. 15) have punched or perforated the sheet material P which may be paper, cardboard, leather, etc. At this time, a

punching stem 43 is slidably disposed in an alined paper exhaust bore 45 of its anvil A and is awaiting the return stroke of the handle and suchareturn stroke is limited by the lug 55' striking the top face of the boss 54 (Fig. 2)

Where the shaft S is coupled 0r interlocked with the teeth 58 of the slidably or reciprocably guided tools T, rotational displacement of the handle will slidably but vertically displace these tools. Where only one or perhaps possibly two cutting tools are sufficient in actual practice, the remaining tools not needed may be readily uncoupled from the shaft. For this purpose, it will be noted that with each cuttingtool is provided a lifting knurled member 55 in the form of a. sleeve rotatably and slidably surrounding a cylindrical extention 56 projecting from each cutting tool T and beyond its respective header.

In the form illustrated in Figs. 10 and 12 the lifting sleeve 55 cooperates with the overhanging rim of the head 5'! to elevate the cutting tool T from the coupled relation thereof (Fig. 10) to its uncoupled relation with the tooth 48 (Fig. 12).

i The uncoupling relation is maintained by manually rotating the lifting sleeve 55 after having been manually elevated to position its lower face onto the top face of apost 58 (Fig. 12) fixedly fastened to an associated header H. Thus if the lever or handle be operated in either direction and if the cutting tool is uncoupled therefrom, the cutting tool will not be displaced, in that shaft S rotates idly (Figs. 12 and 14) insofar as r it relates to the uncoupled cutting tool.

Where it is desired to couple a cutting tool T to the shaft, sleeve 55 is rotated until its slot 6! (Fig. 12) receives the post 58 at which time the sleeve is dropped, thus the cutting tool is freed and falls by its own weight provided the lever 52 is in its fully rearward position to permit tooth 48 to by pass theupper lip 5|) and engage the lower lip 5 l By this action, the tooth 48 is again .interposed in the slot 49 of the shaft S. In efthe tool lifting means illustrated in Figs. 4, and

13 to 15 inclusive and in the latter it will be observed that the rotatable and slidable sleeves 55 are each provided with an upper attenuated rim defining with extension 56 an annular chamber 62 wherein a-normally expandible ahelicoidal' spring 63 isconfined between the annular shoulder 54 (Fig. 4) and the overhanging rim, of the head 65 of the setscrew 66 having it's-shank 61 removably and thre'adably connected to t e threaded-bore =68 0f the extension 56 :of: the cutting or punching tool T, the arrangement being such-that-if one or more of the cutting tools be coupled to the shaft and thereafterthe handle lac-depressed or retracted the extensions 55 are not onlydisplaced relative to the knurled sleeves 55- but in addition-heads 55=slide in the chambers Gland onthe cutting strokeof the tools, spring i63-is-compressed by the rim of head 65 (Figs and-upon the-return strokeof the operatinghandle the lips 5| drive the lower 'inclined faces of theteeth 48 to engage and-elevate the cutting tools and the formerly compressed spring 63 expands and facilitates on the return stroke of the oscillatable shaft S,'the withdrawal of the punching stems 43 from the stack P whichmay be as previously stated of paper, cardboard, leather and/ or thelike.

4 lb-selectively uncouple the cutting tools T of Figs. 4, and 13-15-the handle is first retracted fully, for example, as indicated by the dash and dot-lines in Figs. 4 and 14. Thereafter a sleeve is raised against the resistance of its associated-spring '53 and positioned on-the top face ofthe adjacentfixed post 58 (Fig. 14), thus unoou-plingthe cutting tool. Therefore even though the shaft may be rotated, the uncoupled cutting tool remains in raised but idle position. To again couple the cutting tools of Figs. 13-15 to the oscillatable shaft S, a respective sleeve 55 is rotated until its slot or-keyway l'li lines up to receive an associated pin'58 and thereafter finger pressure is released. Spring '53 then expands and automatically-retracts its sleeve which now yielding rests on the top face Of itsheader (Figs. 4 and '7) With the teeth 48 of the cutting tools interlocked with the shaft,- that is, coupled thereto, on the downward or operating strokeof the handle, the-upper lip 50 of the oscillatable shaft S coacts with and engages the upper inclined face of these teeth to depress the punching or cutting tools so that the punching stems 43 are downwardly displaced and: through the stack of papers, cardboard, leather and/or the like inserted into the alined gaps 45 of the several headers, and of course onthe return stroke lips 5i act on these teethto elevate or return cutting tools. 3 To preclude lateral displacement ofthe shaft S, the latter includes a groove 1-! (Figs. 7 and 18) for: removably receiving and interlocking with the enlarged end '12 of-the movable pin 13 slidably guided in the exteriorily threaded bushing it (Big 18) -mounted on the left hand brace it (Fig. 9) of the frame of the machine. By grasping, head 75, pin 13 may Joe-slidably withdrawn from the groove 7!, thus unlocking the'shaft S. Hence the latter may be slidably withdrawn from the headers, for example, in Fig. 9, shaft S 1s shownmoved laterally to the right and disengaged from one header but if desired the-shaft can be: withdrawn from all of the headers and laterrethreaded therein.

Where a header H is disassociated from shaft S,- it may be readily replaced by another header or removed frornthe machine. If it is desired to, remove'a header, its rearwardly extending threaded set screw 16 is first disengagedfromra threaded'or notched supporting rod or reinforcingmemb'er Tl interconnecting the spaced braces l0 and thereafter the rear portionof the header is tilted, upwardly .:(note dashzand dot lines Fig. 8),;that is- -the, tail portion 18 "embodying the 6 notch .19 may be lifted-to be-free lot-the sustain= ingrod 11, and consequently the forwardly extending lip of the anvil is-correspondingly tilted-and may besl-idablywithdrawn fron:1'l;ve-.-. tween the rearmargin '8 I andthe shelf or-brace l 2 which dn-fact characterizes a support forithe anvils whichupon the positioning of a header back onto -.themachine, may be readilyplaced on the-shelf l2 to permit the reception :ofthe rear'margin 8| of the rear panel 14 in a reentrant recess 82 ofthe anvil and-against thestop shoulder 83. 'Ihereafterthe tail-portion 18 is swung downwardly for reception of the -fixcd rod H in the notch 19.- Thus each header is also removably sustain-ed bythe shelf or I. brace 12 a groove in the supporting rod 11.

According-to the invention the headers may be set in predetermined positions along the shaft S and this is accomplished in first disconnecting the threaded set screws 16 from the rear supporting rod '11, and thereafter slidablyshifting one-or more of the several headers until thesides of' attenuated portions 4-1-0f the cutting-tools T ride into a gap ornotch 85along the-shaft Sand many notches or keeper means as 85maybeprovided as desired forpredetermined-spacing or indexing of the-headers; In'Fig. 151, thecutting tool-T has its reduced or attenuated-portion 41 out of notch 85 and Icy-sliding the-header. along shaft S, the reduced portion 41 snaps intothe positioning means or notch 85 (Fig. 16) thus automatically interlocking with the wa1ls th ere.- of. Because of this actiomanytwo headersialong the shaft may beconveniently andquicklyshifted for predetermined. spacing of their cutting :tools although each-header may be .quickly::shifted from its selected position by lifting its tool,upwardly to remove the reduced portion from the notch 55 and thereafter sliding. thesheader lengthwise of the shaft.

Further in accordancewith the .inventionathe extent to which the stack .of-material ,orua sheet thereof may be inserted into thenalined-gaps' 46 in the headers maybe controlled, and regulated. To this end it will be observed that associated with eachheader is toothed rack (Figs! 4-6) adapted to be projected into an associated gap 45. Each rack 99 slidably guided in a slot Bi -and meshes with a pinion 92 fastened to a stub. shaft .93 desirably journal-ed in a header and fixedly fastened to each shaft 93 is a manipulatable-and readily accessible wheel or graduated disc 94 having suitable indicia thereon; It followsthatby rotating the indicia wheel 94 its associated rack as may be projected in and out of the adjacent gap 46 (note dash and dot lines Fig. 6) regulating the indicia carrying wheels relative the datum line or index 95 inscribed on associated bosses 96, predetermined projection of the, several racks may be controlled and such settings are maintained by the clamping of the threaded members 91, which selectively are adapted to be removably projected in the annular races or grooves 98, against the wall of such races. If therefore the racks have been adjusted for predetermined projection into the gap 46, the extent of insertion of the stack of "material into the gaps 46 is limited in that the forward ends 99 (Fig. 6 of the racks serve as'stop meanshand. are desir .ably lined up in accordancewithithe setting of the indicatorwheels 94.v Whileeaoh-rack fills '7 slidably guided, each is limited in its displace mentby a'fixed pin or key I00 extending from the fixed guide block 9|! and fitting into'a companion keyway or guide slot'llll in the rack.

In operation, the stack of material to be perforated, which may be paper, is first'positioned on the platform defined by panels [4 and 22 and against the stop 30 which previously has been adjusted and clamped. The sheet of paper P is insertedinto the alined gaps or throats 46 of the anvilsA of the headers H. With the selected punches 'or cutting tools T coupled to shaft S, handle 52 is rotated downwardly. By this action, the coupled tools T perforate the stack as desired and thereafter the handle'is retracted to its normal raised position. The depth of all slots 46 is the same and of course such depth may be shortened or enlarged upon adjustment of the racks 90 by the regulator wheels 94.

If desired locking pin 13 may be raised out of the end groove ll (Figs. 9 and 18) and the drive shaft thereafter may be bodily longitudinally displaced and outwardly whereby lug or projection 53 of the pivoted handle 52 clears the boss 54. It follows that the handle 52 may be lowered and positioned on an adjacent block 21 (Fig. 1) and thus takes up less room for packing and transportation purposes. In such out of the way position, the 'slidable locking pin 13 may be again lowered anddropped into notch I02 (Fig. 9) hence again interlocking with shaft S, thus preventing unnecessary withdrawal of the shaft in its lowered and out of the way position of the handle.

With the locking means 15 clear of either of the grooves H and IE2, shaft S may be completed slidably and rectilinearly Withdrawn from the headers and the punching tools thereof readily removed or replaced. Or the headers may be now removed from the machine and new headers substituted without dismantling or removing the reinforcing rod 11 from the frame. Thereafter shaft S may again be threaded into the headers and interlocked or in mesh with the punching tools which selectively may be lifted or uncoupled to be out of mesh with shaft S if desired.

Various changes may be made in the details of construction and arrangement of parts without departing from the spirit of the invention or sacrificing any of the advantages thereof inherent therein.
