so Claims.

The invention relates to perforating machines for receipting stub bills such as tax bills and those of public service and utility companies by perforatingl the date of payment and other data v on the bills, and has more particular reference to an ejector' for discharging the stub portion of the bill from the die opening of the machine into a locked receptacle or onto a table -or desk.

An object of the invention is to provide ejecting mechanism for perforating machines which will be operated by stored energy derived from the action of the handle in performing the perforating operation and the actuation of which will be initiated to cause ejecting of the stub portion of the bill by the machine'as the same completes the perforating operation. This mode of operation is important as it is necessary to have the ejecting action take placeafter the perforating operation has been completed in order that the punches will have been lifted from the openings clear of the paper.

A further object is to provide an ejector in which the ejector blade will have a close sliding t in the die opening of the perforating machine -to prevent even the thinnest bill stubs from Ybecoming lodged above or below the ejector blade.

A further object is to provide novel means for locking the handle of the machine in the event the ejector blade becomes lodged in the die opening where serious damage would occur to the punching dies should a perforating operation take place.

A further object is to provide an automatic reversing lock for the handle requiring the operator to proceedwith the perforating operation 'when once initiated by downward movement of the handle and to also continue upward movement of the handle to complete the operation -after said movement has been started.

A further object is to provide ejecting mechanism for use in connection with perforating machines which will be simple in construction, positive in operation, and which will not easily get out of order.

With these and other objects in view, the invenv tion may consist of certain novel features of construction and operation, as will be more fully described and particularly pointed out in the specication= drawings and claims appended hereto.

In the drawings which illustrate an embodiment of the device wherein like reference characters are used' to designate like parts- Figure 1 is a front elevational view of aperforating machine showing the same equipped with the ej ectingmechanism of the invention;

'Figure 2 'is a vertical sectional View showing in side elevation the mechanism for performing the ejecting operation;

Figure 3 is a horizontal sectional View taken through the vdie opening of the machine and showing the ejector bladeand mechanism in top plan;

Figure 4' isa Vertical sectional View taken substantially on the plane indicated by line 4-"4 of Figure 2;

Figure' is a detail sectional view of the spring casing in unwound position;

Figure' is a viewsimilar to Figure 5 'showing the sprng'casing in wound'position and locked by the locking lever;v and Figure 7 is a perspective view showing the typeA of bill perforated by the present form of perforating machine.

The perforating machine of Figure 1 comprises a'base I0 having paper supporting surfaces formed by the die block 11 and an oscillating head 12 carrying a number of dies for perforating a bill with various data such as the date, the name or initial of the company, and other desired information, the date being changeable by adjustment of the pins 13. 'Ihe oscillating head is suitably supported for'movement from the base 10 of the machine and is operated bythe handle 14 xedly secured to the shaft15, Figure 4, journalled in the projecting hub 16. With the handle in inoperative position, as shown in Figure 1, where it engages with the stop 17, the die opening`l8 is unobstructed to permit the insertion between the punch holder 19 and the die plate carried by the block 11 of a bill or other form 20 to be perforated by actuation ofthe handle 14 downwardly causing downward movement of the selected dies in the head 12. Return movement of the handle lifts the dies to free the form, whereupon the same may be taken from the machine.

Perforating machines of the type described are commonly used to receipt bills upon payment of the same by the customer and in order that the company may retain a record of thepayment the stub portion 21 is simultaneously perforated with the date and other information to indicate the employee operating the machine and the number of the machine. Simultaneously with theperforating operation the bill is severed' Aon the dotted line 22 by the knives 23, the upper knife being operated by the oscillating head, while the lower knife is 'fixed to one of the paper supports 11. The presentl invention 4is more particularly conejected stub portions of the bill and which will prevent access thereto by the employees after the same has been perforated and severed as described.

The paper support 11 for the stub section of the bill is provided with grooves 24 on the respective sides thereof, receiving lugs 25 supporting for .a close sliding fit over the surface 11 an ejector plate 26 having a right hand projecting portion 27, Figure 3, secured by rivets 28 to a reciprocating bar 30. Supporting means for the bar comprises al channel guide 31 supported horizontally from the `machine by the member 32 and having retaining strips 33 suitably secured to the face thereoffor retaining the bar while permitting reciproeating movements thereof.

The ejecting mechanism, Figures 2, 3 and 4, isv

confined between one side of the machine and a supporting plate 34 having an integral base portion 35 providing a flange 36 secured by screws 37 to the base 10 of the machine. The handle 14 fixed to the operating shaft l5, the outer end of which is journalled in plate 3,4, has secured to its hub portion by rivets 38 an inside cam plate 39 extending rearwardly and having securedthereto a pin 40. Also secured tothe hub `portion of the handle by` the rivets 38 is an intermediate cam plate 41 carrying the release-pin 42 and an outside cam plate 43,'the function of which will be more particularly described. i

Pivotally secured to the base portion 10 of the machine is an oscillating lever 44 having an elongated slot 45 centrally thereof and an oblong tationon shaft 5i) supported from plate 34by the boss 5l to which the shaft `is secured by the set screw 52, preventing rotation of the shaft.

The spring casing houses a coil spring 53the` inner end of which is xed to the shaft `50 by rivet,54,while the outer end of the spring is secured to the casing by the rivet 55. The plate 56 suitably secured to an internal shoulder formed in the casing provides the pivot pin 57 for the pawl 58 which is held in engagement with a notch in the disc 60 by spring b1 having one end secured to the free end of the pawl and the other end to the casing.

The disc held to the shaft by the thrust washer 62 suitably pinned to the outer end thereof is adapted to be frictionally engaged with plate 56, that is, with the spring housing 48, by they spring washers 63 4and 64, interposed between therdisc and the plate. Connection between the disc 60 and the oscillating lever 44 is effected by the pin 65 carried by the disc and which has location within the elongated slot 45 in the lever so that when a completed revolution of the disc takes place through rotation ofthe spring casing 48 the oscillating lever 44 will have movement from its extreme right hand position, as shown in Figure 2, to its extreme left hand position and return. This movement ofthe oscillating lever will reciprocate the bar 30 and thus the ejectorA plate 26 to cause discharge of the bill stub.

A feature of the invention resides in the means for rotating the spring casing one revolution, which includes a sliding rack bar 66 having a bifurcated end retaining a roller 67 and mounted for vertical sliding movement within the member 68 located to the inside of the supporting plate 34. To cushion the upward movement of the bar the `member 68 is provided with a cap 70 secured to the supporting plate 34 by screws 71' providing a layer of felt 72 or like cushioning material as a stop for the bar. Meshing with the rack bar is a pinion 73'loosely mounted on shaft 50 and being secured to the spring casing 48, withV the result that movement of the sliding rack barf6`6 will cause rotation of the pinion and vspring casing to wind the coil spring or to unwind the spring depending on the direction of rotation.4 The tension exerted by the coil spring causes clockwise rotation of the casing 48 and thus tends to maintain the rack bar in its Up positionv where it contacts with the cushioning stop 72. v

The stud shaft 74 projects inwardly fromthe plate 34 and rotatably supports the locking lever` 75 which is biased by the spring 76 so `that locking relation is maintained between the lever and lug 77 to hold the casing in position with the sliding rackbar in engagement withV the cushioning stop. Normally thelocking lever is held out of engagement with the lug 77 by engagement of the release pin v42 with the lever, the pin being carried by the cam plate 4l on the handle and relatively positioned with respect to the handle so that the pin engages the lever to release the same `when thehandle is in raised inoperative position.

forated is first located in the machine and properly positioned by the paper stop 78 secured by screws 79 to the right side of the machine, Figure 1, whereupon the handlegrip 14 is grasped by the operator and pressed downward to lower the handle 14, giving a counter-clockwise rotation to the cam plate 43, Figure 2. The cam plate engages with roller 67 on the sliding rack bar, forcing the same downwardly, rotating the pinion 73 andv the spring casing in a counter--clockwise Adirection to wind up the coil spring 53. This rotation of the handle releases pin 42 from engagement with the locking lever 75, causing the lever to assume a locking relation with the casing. No interfer-` ence, however, takes place between the lug 77 and the lever since the rotation of the casing is counter-clockwise. The effect of this rotation of the spring casing is to rotate the pawl 58 with respect to the disc 60, which is frictionally engaged andr form a perforating operation is suiiicient to rotate' the casing 48 a complete revolution which willv bring the pawl 58 into engagement again with the notch in the disc 60 andthe'lug 77 into locked position with lever '75. Upward movement of the handle cause rotation of the cam plate 4l to again contact pin 42 with the locking lever 75 although engagement does not take place until the lever substantially reaches its inoperative position. Releasing the locking lever frees the spring vcasing and as the same hasbeen wound by its counter-clockwise rotation above described, it proceeds to unwind, thatis, tol rotate in a clockwise direcation whether'thesamebeby the hand of the tion. Any movement of the casing in this direction, however, positively carries with it the disc 50 as the pawl 58 has engagement in the notch in the disc,` with the result that lever-14` is oscillated causing a reciprocation of bar 30 'and the ejector plate 26 to discharge the'bill'stub. It is te be noted that the spring casingl rotatesI one revolution and that the ejector blade has reciprocation forwardlyv of the die opening and then rearwardly to its initial position outof the path of the punching dies.

The locked receptacle previously referred to isl indicated at 80, being secured tothe base l0 of the machine by threaded` screws 81 and having a closure which may be locked by an official of the company, preventing anyone else vfrom having access to the interior of the container. In accordance with the invention an opening in the vbox is positioned immediately adjacent the die opening to receive the discharged stub bills automatically ejected by reciprocation of the ejector plate 26.

To prevent an incomplete operation of the perforating machine to perforate but only partially sever the same, whereupon the operatorwould be able to remove the entire billffrom themachine and retain the stubv portion, the invention provides a reversible locking pawl 82 rotatably mounted on the stud shaft 83 projecting inwardly rom'plate 34 and which is resiliently held in vertical position by the coil spring `84. The cam plate 43 is of rounded contour on thev lower portion thereof, having a plurality of notches '85 formed therein, the end notches being ofa. vwidth to permit the locking pawl 82 to assume a vertical position, while the intermediate notches are of considerably less width thereby preventing` rotation of the handle in both directions. 'Ihe structure is reversible in operation, preventing upward movement or" the handle until the full downward stroke of the same has been completed and in a like manner preventing any downward movement of the handle after upward movement of the samehas been initiated.

Serious damage would occur to the punching dies should a periorating operation take place with the ejector plate 26 lodged forwardly of the die opening and in order to prevent movement of the handle downwardly to perform a perforating operation, when such is the case, the invention provides the lever 86 pivoted to the-baselO as at 87 and having limited pivotal movementby reason of the pin 88 which is located within an arcuate'slot 89 provided in the lower end ofthe lever. The freeV end of the lever is notched atv 90 for engagement with pinrl() on the cam plate 39, the lever being biased by spring 91 to'locatethe parts in locked position where downward movement of the handle will be prevented. Projectving from one side/of lever 86' is a; stop l92 p'osiinvention provides ejecting mechanism for auto-V matically discharging the stub portion of the perforated bill or other business form andwhich mechanism does not require extraneous'motive power but is designed for operation by the same power means performing the periorating operoperator or by a suitably connected electric motor. It willbeappreciated that the movement rof theejector blade is rapid so as not to interfere with the perforating operation and whichfimparts suiicient momentum to the discharged stub portion to veject the same clear of the machine. This feature is principally secured by the spring-energized casing having the ability to store up energy and expending the saine substantially instantaneously. The invention has been found to perform satisfactorily over a klong period of time without requiring any adjustment whatever of the parts-and even should a bill stub become lodged between the ejector blade and the top or bottom of the die opening to hold the plate in the path. of the-'punching dies' the operator would' be immediately warned of the danger the lever"86` would automatically engage with pinHlO yto prevent further Ioperation of the perforating machine.

'It is' to'be' understood that I donot wish to be limited by the exact embodiment ofthe device shown, which is merely by way of illustration and'notlimitation, asvarious and other forms ofthe device 'willof course-be apparent to those skilled in the art without departing from rthe spirit of the invention or the scope of the claims.
