PERFORATIN G-MACHIN E.

Specification of Letters Patent.

Patented Nov. in, 1915.

Application filed June 24, 1914. Serial No. 846,984.

To all whom it may concern Be it known that I, FREDERICK HART, a subject of the King of Great Britain, residing at Poughkeepsie, inthe county of Dutchess and State of New York, have invented a new and useful Improvement in Perforating-lllachines, of which the following is a specification.

This invention relates more particularly to machines for perforating sheets of paper or other material with lines of perforations extending across the sheets at predetermined distances apart, as, for instance, in sheets which are used for check books containing on each sheet several .checks'separated by lines of perforations. The invention is not,

however, necessarily restricted to perforate.

ing machines but is applicable also to other machines of an analogous nature provided with punches or other tools for performing operations at predetermined points on the sheets.

The objects of the invention are to pro duce an eflicient and desirable semi-automatic machine which can be manufactured at moderate price and which is capable of rapid operation and can be quickly andconveniently set to operate upon sheets of dif ferent sizes, or to perform the operations in different desired positions on the sheets.

Briefly stated, the machine comprises a mechanism provided with punches, needles or other tools which operate'upon the sheets, a feeddevlce which is moved by hand to feed the sheets to the perforating mechanism, and gages movable with the feed device which control the actuation of the perforating mechanism and are adj ustable so as to cause the perforations or other operations to be performed in any desired relation on the sheets. i

In the accompanying drawings, consisting of six sheets: Figure 1 is a side elevation of a perforating machine embodying the invention. Fig. 2 is a plan view thereof. Fig. 3 is a. rear elevation thereof, partly in section in line 33, Fig. 1. Figs. 4; and 5 are fragmentary longitudinal sectional elevations thereof in lines-1% and 55, respectively, Fig. 3. Fig. 6 is a fragmentary plan view, enlarged. of the sheet feed device detached. Fig. 7 is an enlarged sectional elevation thereof in line 7 7, Fig. 6. 8

Fig. 12 is a fragmentary side elevation thereof partly in section in line1212, Fig. 11, showing the position of the parts whenthe punch is raised. Figs. 13 and 1 1 are similar viewsshowing successive different positions of the stop means for the feed device. Fig. 15 is a transverse sectional elevation in line 1515, Fig. 12. Fig. 16 is a fragmentary plan view showing a perforating machine of slightly modified construction. Fig. 17 is a rear elevation, partly in section, thereof.

The main frame A of the machine may be of any suitable construction, that shown consisting of an upright transverse skeleton casting supported on horizontal feet a, and horizontal brackets or arms a and c which extend respectively forwardly and rearwardly from the upright frame. Themechanism for perforating or otherwise'operating on the sheets may also be of any suitable construction, as the desired style of work or other considerations may require. The perforating mechanism shown in the drawings is constructed as follows:

B represents a vertically-reciprocatingcross head extending transversely in the ma chine and provided at its lower side with punches, needles or other tools Z) foroperatlhe cross head.

which is suitably journaled on the main frame and is provided at its ends with cranks or eccentrics a which are connected by pitmans 0 to the ends of the cross-head. This crank shaft is normally stationary but is coupled to and uncoupled from a continuously rotating pulley D sleeved on the crank shaft bya clutch and actuating mechanism thereforwhich are controlled by the gages on the feed device,as hereinafter described, so that the crank shaft makes one revolution and reciprocates the cross-head once each time one of the gages operates the controlling device of the clutch actuating mechanism. The pulley D may be driven by an r '.The block 9 is adjustably secured by a electric motor (Z connected by a belt cl to the pulleyD, or in any other suitable way.

E represents a feed table which is supported, in front of the reciprocating crosshead B, on the front frame-brackets (1.". The

frame bracket a at the right-hand side of the machine preferablyextends up atthe side of the feed table so as to be flush with the upper surface thereof.

Frepresents a feed bar or device which extends transversely across and is slidable forwardly and rearwardly on the feed table.

Thesheets are laid on the feed table against the rear edge of this feed'bar and the latter is shoved rearwardly by hand to advance the sheets to the perforating mechanism. In the construction shown in Figs. 1-15,the feed bar F consists of a flat sheet metal strip having an upturned front edge anda raised rib f formed by a channel-shaped bar; secured on the fiat metal strip. The feed bar is rigidly secured at one end to a guide bar f which extends forwardly and: rearwardly of the machine and. is arranged to slide in a guide groove f in the adj acent front and rear frame-brackets-a and a ft is a gage for the side edgesof the sheets which is adjustable transversely of the machine on the feed ban as may be required to accommodate sheetsof different widths. Asshown in Fig. 7 the side gage isslotted toslidably lit the channel rib f of the feed bar and is provided with a thumbscrew f for pinching the upper flange of the rib f in the slot of the gage to secure the gage in the position to which it'is adjusted. The side gage is retained perpendicular to the feedbarby a shoulder ffll ig. 7, at the rear end of-the gage sliding against the rear edge of the feed bar. The feed device can be of any other suitable construction.

G, G, G G represent the gageswhich control the operation of the perforating mechanism. These gages are connected one in advance. of the other, to thefeed device, so that when the latter is moved rearwardly in feeding the sheets to the perforating mechanism thegages will move therewith which it isdesiredto make in a sheet, and the. gagesare ad ustable to .diiferentposh tions relative to the feed bar toenable'any desired-location of the lines of perforations in the sheet. "The gages maybe constructed and; adjustab'ly secured to the feeddevice'in' clamp bolt 9 having a head seated in an undercut groove g in the guide bar, and a nut g oirthe upper end of the'bolt; A spring 9 holdsthe finger g against astop 9 whereby the finger is adapted to yield and pass by the controlling device H when the feed device is pulled forwardly, butis held rigid with the block 9 and adapted to engage and move the controlling device H when the feed device is moved rearwardly withnthe sheet to be perforated.

Thevgages can be conveniently placed in the proper position by marking-on a sheet the points where the lines of perforations are tobe made, then placing the sheet on the'feed table against a setting block or. gage g on the feed bar, as indicated by dotted lines in Fig. 6, and adjusting the gages GG on the guide bar f with their rear ends registering. with the marks on the sheet. The setting gage g is so located with reference to the rear edgeof the rib 7 of the feed bar F: that-when the sheet is placed against this edge to be fed to the perforating mechanism the points marked on the sheet will be located beneath the. punches when the controlling device H is actuated by the respectivegages Gr'Gr to cause the'operation of the perforating mechanism.

The; controlling device H is operatively connected to the clutch mechanism which connects the crank shaft 0 for the perforating mechanism with itsdrive pulley D, and each time the controlling device is moved by one ofthe gages; the clutch mechanism is, operated tocause one revolution of the crank shaft and one reciprocation of the cross head B. In the construction shown the controlling'device consists of a plate orlever whichis pivoted in the frame-bracket a," at the outer side of theguide'bar f" and has an inclined upper face which normally projects up into the path of the fingers g of the gages G- bd, so that aseach gageis moved past the controlling device Hits finger will engage and depress the controllingydevice. Themovement of the controlling .device is transmitted'by a push rod h toa'lever' it, see Fig. 3, which is connected by'a link k to a trip lever it for the clutch mech anism. Thecontrollingdevice Hand the. push rod k are preferably located in recesses in the outer side of the frame-bracket a, in which they are retained by a removable cover-plate it? and the levers h and h? are suitablyfulcrumed on the main frame with the triplever h extending into proximity to the clutch mechanism. ;*A spring h- ,.Fig.

12, connected to the trip lever, acts to return the controlling device H to the normal raised position shown in Fig. 12, after 'it has been depressed by one of the gages GG and hold it yieldingly in this position.

Any suitable clutch mechanism may be employed which when tripped, will connect the crank shaft 0 of the perforating mechanism to the drive pulley D and automatically release it after one complete revolution. The clutch'mechanism shown in the drawings (see Fig. 3) is the same as that disclosed in Patent No. 828,546, granted August 14, 1906, to myself, assignor to R. A. & CLS. Jonas, and is only illustrated and described herein suiliciently to enable an understanding of its operation.

I represents a clutch member which is slidably mounted on the crank shaft 0 so as to turn therewith, and is adapted to interlock with a cooperating clutch member I formed on or secured to the pulley D. e

i represents a latch-tripping finger which swings from one arm of the trip lever 71 and has a hook at its lower end adapted to engage under a shoulder on a latch 2'.

In the normal or rest position the sliding clutch member I is held out of engagement with the cooperating clutch member against the action of a spring 11 by a stronger spring which connects the upper ends of a clutch shifting lever 2' and a safety lever i and the parts occupy the position shown in Fig. 3, a detent 2' being held by the latch 2" against a lug i on the hub of the sliding clutch member I and pressing the lug against the inclined face of a lug i on the safety lever When the trip lever is rocked by the de pression of the controlling device H, the trip finger i is lowered, and when the controlling device and trip lever h are returned by the spring h the trip finger engages and lifts the latch z". The sliding clutch member I is now moved by its spring I i into engagement with the cooperating clutch member, and rotates the crankshaft, thus carrying the lug i away from'the detent i. The detent is then pressed out by a spring i and the latch again drops into engagement with the detent. When the lugz' comes around into engagement with the beveled face 2' of the detent 21 it and the clutch member are moved over against a stationary projection 2' on the frame,,and as soon as the lug 2" passes this projection e' the spring 2' suddenly pulls the shifting lever 11 and throws the sliding clutch member out of engagementwith the other clutch member, the parts then'being again int-he rest position. "The engagement of the lug '17 with the lug on the safety leverprevents any over movement of the crank shaft C. Thus the crank shaft makes 'onerevolution and lowers and raises the cross head of the perforating mechanism eachtime thecon trolling device His depressed by one of the gages G"G Y K represents a stop device or abutment adapted to engage the gages Cir-G for arresting the feed device F at the points necessary to properly locate the lines of perforations and preventing the feed device from being moved during the operation of' the perforating mechanism until after the punches have been withdrawn from the sheet. This stop device, in the construction shown (see Figs. 12-14), consists of a plunger arranged to slide vertically in the frame-bracket a in rear of the controlling device H, and a spring-actuated latch L adapted to engage a shoulder 76 on the plunger and hold it down out of the path of the gages GG against the action of a lifting spring The plunger K and latch L, asshown, are confined in guide grooves in the frame-bracket a by the cover plate h The latch L is held by its spring Z in engagement with the shoulder of the plunger K and holds the plunger in its normal depressed position shown in Fig. 12, and is retracted to release the plunger by an arm Z on the controlling device H which extends into a notch Z in the latch. When the controlling device H is depressed by one of the gages G-G it retracts the latch L and the plunger K is raised by its spring is to the position shown in Fig. 13, in which the gage is adapted to strike the plunger and arrest the movement of the feed device F. The gage is arrested byv the plunger K just after it passes by the controlling device so that the feed device is arrested before the cross head B descends. hen the cross head descends, a push rod M carried thereon above the plunger K, engages and depresses the plunger, as shown in Fig. 14, and when the gage clears the controlling device and permits itto be returned to the normal raised position the latch L is moved by its spring 1 into engagement with the plunger and holds the same down. The plunger is held down during the upward movement of the cross head, but the push rod M is at-this time in front of the gage as shown in Fig. 1a, and blocks the movement of the gage and feed device until the cross head has ascended far enough to raise the push rod from in front ofthe, gage. The punches will then have been withdrawn from the perforations in the sheets. As shown, the push rod M is arranged to slide in a vertical hole in the cross headin which it is retained by a pin m working in a slot m, andis pressed ClOlVll. wardly by a spring m which is strong enough to overcome the lifting action of the spring 70 for the stop plunger. The push rod is thus adapted to depress the plunger when the cross head descends but" it can yield and thusprevent injury tothe machine in case one of the gages or any lOO I feed deviceto beemoved quiekly in die-lending the sheets and, insure .ot the same. being-aarrested and held stationary,- :atwthe proper points; during-each (operation, ,of the perzfiorating mechanism ,without requir ng-special attentionor skill on" the part of-zthe qperative.
