PERFORATING MACHINE.

Application med June 1, 1920. "Scriai' No.'"385,466.

To all whom it may concern Be it known that I, ALFRE L. DAY, a citizen of'the Unitedfitates, residingat'l roolcline, county of Norfolk, State. oi l'vlassachusetts, have invented an Improvement in Perforating Machines, cit which the" following description, ,lIrCODHQ'C LlOH with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to perforating machines andhas for its principal object tomechanism will n-eterably be adjustableso that it can he set at each? actuation to pen tor-ate the nunibers or characters desired.

The invention has the advantage that it obviates thenecessity'or" 'introilucing a slip or sheet of paper into the machine. to receive the perforated recordbecause the slips or sheets 'on which the pertoratedrecords are to be made' are contained within themachine andare delivered automatically as the machine is actuated.

i In order to give an understandingo-fmy invention, 1 have illustrated in the-drawgs a: selected embodiment thereof which will now be de'scribed, after which the novel features will be pointed out in the appended claims. 3 I p In: the drawings, Fig. 1 is a side View of a perforating machine embodying my invention with a portion broken =out to i better show the interiorconstruction; Fig. Qisa t'ront VlLW of Fig. l: i Fig. 3 is a detail view of the trip mechanisin tor controlling the shears Fig. l is aplan viewot' the mechanism shown in Fig. 3;

Fig. 5 is asection on the line5-5, Fig. 4. The devii-eherein shown comprisesabasc frame 1 having; a throat 2 through which .the slipsioi' paper are ejected andalso having a die-plate situated beneath thei-throat and provided-with apertures to-receive punches 4: which are situated above thethroat and are properly guided '111 their vertical move ment. The punches are arrangedimgroups, and means are provided for selectively actuating'the punches of each group therebyto perforate any desired character-in a-slip or sheet oi? paperwhichi'n aybesupported on the" die-plate 3. Thisselective actuation oE-the punches accomplished by a-matrix memher, as usualinperttorating machines of this type. Iiithe machine isdesigned to perforate a 'pluralityof characters simultaneously; th en it -W1ll be provided with a 'plural-ityot groups ofpunchesA anda corresponding number of matrix members. i In the machinefshown in, the drawing, there; are, four such; groups of punches, and tourma-trix' members, the latter being;indicated-at ally mounted ona shaft 6 carriedin a mov:

a rearward extension 8 which-:is: pivoted'to the baseirame at'9. J'Each'inatrixmember s 5 has the circular tlace 10in which is formed a plurality of groups'otrecesses the recesses of each grouobeing-so arrangedirelative to each other that the-soli d:,.pii rtions; between the recesses represent some particular charber against the punchesgand'.those punches which'stand opposite "recesses will not be depressed but will remain; in their eley'ated position whileithe punches which are ope .posite-sol d; portions of the'matrii: willrbe depressed and forced through the die-plate 3 thereby perforating any slip or sheet of paper which may be resting on thedie-plate.

'llhe matrices may be adjus ed iii-any suitable way. Each is herein shown as havinga circular extension 11' provided with "a thumb-piece 12 which extends through aslot 13 in the head and by which. the matrixinay be turned about the shaft to bringany group of recesses into line with the punches.

The parts thus far described are or may be all; as illustrated and described iii-my copending, application "Ser. No; 9,162, filed May 5, 11920.

In the present embodiment of the invenbeing p ivot ing head 7. Thighead is shown; as'having;

tion the head 7 is givenits movement by means of an eccentric 14: fast on a shaft 15 which is journaled in the base frame 1 and extends transversely thereof. This eccentric is provided with an eccentric strap 16 having an arm 17 which is pivoted to the head at 18. With this construction, each rotation of the shaft 15 will lower the head thereby actuating the punches and thenraise the head again.

.NAssociated with the base frame 1 is a azinejcontaining a plurality of slips or sheets of paper to be perforated, and means are provided whereby upon each actuation of the 2 machine one slip will be perforated and then will be'd-elivered'from the machine.

.'The magazine may be made in various wayswithout departing from the invention. Perhaps the most convenient form of magazinc is that herein shown which is in the nature of a roll of paper which is situated within the base frame 1 and is constructed so-that at each actuation of the machine a length of paper will be withdrawn from the roll and severed and delivered from the ma chine. 19 indicates a roll of paper which is rotatably mounted on a shaft 20 carried by the base frame. The strip of paper 31 from the roll extends through the throat 2 and over the die-plate 3, and means are provided whereby each timethat the punches areactuated to perforate theportion of the stri of paper 31 which is over the die-plate 2), the portion of the stripwhich is thus perforated will be delivered from the throat-2 and will then be severed from the strip thereb leaving an unperforated portion of the strip beneath the punches for the next actuation of the machine.

The feeding of the strip of paper from the roll 19 maybe rovided for in various ways without departing from the invention. One convenient feeding device is that shown which comprises the two feed rolls 21 and 22 rotatably mounted upon the shafts or pins 23 and24l, These rolls may conveniently be rubber-covered or have some friction surface se that they will have sufiicient frictional e11- ward movement.

. only mesh with the gear 26 while the head is being carried through the last part of its up- The parts are shown in Fig. 1 in the position they would assume half of the revolution of the shaft, the head 7' will be depressed thereby performing the perforating operation and during the last half of the revolution the head '7 will be eleg vated. hen the head is elevatedabout half-way or has been raised sufficiently to clear the punches from thepaper, then the gear 25 comes into mesh with the gear 26, and during the final upward movement of the head, the roll 21 is rotated thereby feeding the paper forward," and by the time the head is completely raised and the shaft is brought to rest in the position shown in Fig. 1, the gear 25 will be just clear from the gear Thesize of the gears and the size of the rolls are so proportioned as to feed the paper the proper amount before the gear 25 is carried out of mesh with the gear 26.

If desired, the rolls 21 and 22 may be geared together so that both will be positii' ely rotated.

It is sometimes desirable to have a dupli cate copy of-each perforated record made, and when thisis the case, I propose to employ a. second roll 28 which is mounted on the shaft 29 and which delivers strip of paper 30 through the throat in addition to the strip 31. Both strips of paper may pass hetr-Jeen the feed rolls 2i, 22 and thus be fed simultaneously;

iiy invention also contemplates means for automatically severingfrom the strips 30 and 31 the portion thereof which has been perforated after the perforation has been made, thereby providing the separate perforated slip. This severing of the slips from the strip is accomplished by means of a shear device situated at the delivery'end of the throat 2 and which'is actuated just after the paper has been fed forward sufficiently to eject the perforated portion of'the strips from the throat.

This shear device com prises a fixed shear blade 32 situated above the throat,'and a movableshear blade 33 which is pivoted to the base at 3%. The blade 33 extends beyond the pivot. as shown at 35, and is acted upon by a spring 36 which tends I to swing it into closed relation with the fixed shear blade 32. v I

Means are provided for automatically opening the shears by swinging the blade 33 downwardly into the dot-ted line position while the paper is-being fed and then re leasing the blade to allow the spring 36 to actuate it to shear off the length. For thus opening the blade, I provide a latch 37 which is pivoted to a lug 38 extending from the s de of the head 7 and which operates inia slot 39 formed in the side wall of the base 1.

This latch 37 is acted upon by a spring 40 which tends to swing it outwardly. The lower end of the latch is beveled, as shown at 41, and the end of the blade 33 is provided with a pin42. When the head moves clownwardly, the beveled portion 41 of the latch 37 engages the pin and ,swings the latch backwardly, and by the time the head has completed its downward movement, the latch is carried below the pin and is swung outwardly beneath the pin by the spring 40. As the head rises, the latch by its engagement with the pin 42 will swing the blade into the dotted line position, Fig. 2, thereby placing the spring 36 under increased tension, and carrying the blade below the mouth of the throat so that the strips of paper may be fed forward and delivered therefrom. I

Means are provided for releasing the latch from the pin just at the time when the head completes its upward movement thereby permitting the spring 36 to act to close the shears and cut off the perforated lengths from the strips 30 and 31. This is herein accomplished by means of a lever 43 pivoted to the frame at 44, and one end of which is adapted to engage the latch 37. The other end of the lever is adapted to be engaged by a beveled arm 45 carried by the shaft 15, and this arm is so positioned that it will engage the lever 43 just as the shaft 15 completes its rotation. The engagement of this arm .45 with the lever 43 will swing the lever about its pivot thereby forcing the outer end of the lever inwardly toward the frame and forcing the latch 37 backwardly out of engagement with the pin 42. The engagement of the arm 45 with the lever 43 serves not only to release the latch 37, but also to give the operator indication as to the proper point at which to stop rotation of the shaft l5.- I

The slips which are severed fall onto the platform portion 46 of the frame from which they may be removed by the operator.

I may if desired provide a strip of paper 47 which is wound on reels 48 and 49 and on which a record of all perforations may be made. The portion of the strip of paper between the rolls 48, 49 passes over the dieplate 3 beneath the strips 30 and31, and,

therefore, wheneverthe machine is oper ated, a perforated record will be made in the strip 47. This strip 47 is fed intermittently so'that the successive perforations will be madeat different places along the I strip. This feeding of the strip 47 is accomplished by gearing the roll 49 to the roll 31 by means of an intermediate gear 50 which meshes with the gear 26 and also with the gear 51 on the roll 49. Hence at each feed-- ing movement of the strips 30 and 31, the

strip 47 will be fed forward.

I claim:

1. In a perforating machine, the combination with perforating mechanism compris-.

ing a die plate, a plurality of punches, a ver .tically-swinging head carrying matrices to selectively operate the punches, of a shaft having an eccentric thereon connected to said head for actuating the latter, and

means actuated by the rotation of said shaft 1 and then to raise the head again at each rotil-131011 of the shaft, and means operative during the last portion of each rotation of the shaft to feed sheet material into position to be punched.

4. In a perforating machine, the combina tion with perforating mechanism, of means to actuate it, means to feed a strip of paper so as to bring different portions of it successively into position to be perforated, a

knife for severing the perforated portions of the strip,means actuated by the actuating mechanism for the perforating mechanism.

to swing on said knife in one direction, and a spring to give the knife its cutting movement.

In testimony whereof, I have signed my name to this specification.
