Application. lediNovember 16, 1909. Serial No. 528,306.

To all 'iu/mm it may concern:

lle it known that l, @imanes O. PnAnsoN, a citizen oit' the United States, anda resident ot the borough olf Brooklyn, inthe county ot Kings, city and State of New York, have invented certain new and useful Improve ments in Pertorati1igMacl1ines, of which the following' is a specilica tion.

My invention relates to perforating machines such as are used to punch holes in cards or the lilre, in ditl'erent positions thereon, correspniding` with ditl'erent numbers. For exai'nple, it may be used to pertorate cards which are to be assorted or distrib uted by an automatic machine. o The object ot my invention is to improve upon apparatus of this kind, and to provide a. simpleautomatic machine which has decided advantaf s over those heretofore known in the art.

lf will describe my invention in the following specification and point out the novel Yfeatures thereof in the appended claims.

Referring to the drawings, Figure l is a. front elevation ot my improved perforating machine. l" 2 is ay sectional plan View ot the machine. the section being taken on the line 2*-2 of Fig. l. A portion of this ligure is` broken away to more clearly show the construction. ln Fig. l have shown the machine in. side elevation, and in Fig. l?

l. have shown it in sectional side elevation, with the section taken on the line 4-1l of Fig. l. Fig. is a dcthil ot' a. pawl-actuating` mechanism which is shown in Fig. 3, and Fig. t3 is a detail of a holding mechanism which is on the opposite side of the machine than that illustrated in Fig'. 3j

Figs. 7 `and 8 are, respectively, a sectional elevation and a sectional end elevation of a ratchet and pawl mechanismwhich I use in carrying out my invention. The section in Fig. 7 is taken on the line 7 7 of Fig. 3, and that in Fig. 8 is taken on the line 8 8 of Fig. 7, looking in the direction of the arrows.

Like characters of reference designate corresponding parts in all of the figures.

l designates the stationary frame ot the machine by which its various parts are supported. l1 is its base which may be integral with the frame as shown.

l2, 1Q are brackets projecting Jfrom one side ot the base and arranged to form bearing/ster a drivinl haft 13.

l-l is a braclie ting from the oppo- Y site side of the trame and supporting,l by

a link l ay lever 1.6 which is arranged to be reciprocated by means Otan eccentric 17 keyed to the shaft 13 and connected with the outer end of lever lf3 by means of an adjustable connecting rod 18.

19, 19 designate vertical guides which are ailixed to and form a part of the supporting frame.

.20 is a platen aliixed to the base l0. This platen is provided with a plurality of openings 2l correslionding inr number, size and shape with the punches which I will presently point out. yThe base is left open below these holes to allow the/cutout card-board or other material to fall away.

At 22 and are stationary guidesyolres for holding the punches in alinenient with the openings 2l. These yoles also form a part of the stationary frame. The punches disposed in four parallel rows, each roiv cemprising two sets of punches, ten in each. set. Spiral springs 'such as 24C' surround these punches and, abutting against the yoke 22 and a. collar such as 25 on each punch, are arranged to maintain the punches in their raised positions in which they are shown in the drawings.

It may be seen from the draw-ings that cards or strips of paper or card-board may be passed between the platen 2O and the yoke 2.2, and through the machine when the punches are up. The frame is cut away at 10:* so that it does not obstruct-` the passage of such material. It is the object of this invention to depress certain of these. punches at each downward movement of the lever 16, and to automatically change the particular punches thus depressed at desired intervals.

A movable head is connected with the lever 16 at 3l. This yead is supported by moved up and down with the lever 16,"lrut is held against lateral movement. This head has two arms or brackets 32 which support the other movable parts of the mechanism which I will now describe.

33 is a shaft rotatably su ported by the arms 32. Upon' one end o? this Shaft is affixed listar-wheel 34 withr which a spring-` pressed pawl 35 .engages tol-,hold the shaft aga-inst rotation when it is not acted upon by other parts of the machine. The shaft 33 is directly above and parallel with the two sets 'of punches designated by Af are designated by the letters A, B, C, and D,

the frame 10 and the guides 19 so that-it is,

.about fixed to "ie shatt are two cylinders 3o and 87 tron. hich project radial pins 51S. Each ot these pins is on a circle directly above one of th.l i .,iiclies, hut. all olE the pinsl are spaced the .'.fvlinders in such a manner that by rotatingr the shaft and cylinders any one of the. pins on each cylinder may be brought into vertical alinenient. with its respective punch. The two sets of punches with their cylinders and act rating pineare duplicates in the particular arrangement illustrated so that. when one ot the pins tor the first` punch of one set in the row designated b v l) is brought into alinement therewith, one ot the. pi tor the *1"* punch in the second litt in this row will also he in ravierative position. lt is obvious that the vertical reciprocatory movement ot the hea/tl il() will then cause two punches to he deprr and to perlorate any card or paper which may be between the platen 2t) and the yoke at the time. A partial rotation oi the shat't 33 will move ay and 'tiring the pins over the. lirst pins a the second punches in each set into operative positions. .l have shown ten punches in each set and two sets ot ten pins on each c vlint'ler. so that one twentieth of a revolu-V tion ot the shat't 33 will be necessary to move the pins along each step, and one halt' a rtwolution ot' the shat't` 3? will lanse. all ot the punches in the row l) to he succes` sively depres ed. The. two sets ot' punches designated hy B are similari)v actuated hy pins upon cylinders z bovc them.

el() is a shaft upon one end of which is a holdingv star-wheel ill.

ft2 and are the two cylinders al'lixcd to the shaft. and their projcctin` pins are designated by il.

is a gear on the end ot shaft l0 which is in mesh with a'similar gear Rt) of the same size on the end ot shaft 233.

l will now describe. the mechanism by means of which the shafts 33 and 40 are automatically rotated. lipon the end ol shatt 33 is looselymounted a yoke .30, one portion ot which is provided with gatrteeth 51. These are in mesh with a stationary rack which is allixed to the frame lt). .lt is evident that the vcrti :al reeiprocation ot the. head S0. which carries shaft 2.325, will cause the yoke to be swung' back and forth about its axis. which is thc center of shaft. 23S.

Pivoted on a pin 53 in yoke 50 is a spring` Apressed pawl t3() which is provided with a plurality ot pawl surfaces or teeth (il, (3Q. (33 and (i-lset at dill'erent heights. shown in Fig'. T. The iii-st ot these. ttl. is arranged to eneage with the teeth ot a ratchet-wheel G5 which is loosely mounted upon shaft 3B. This wheel is provided with twenty teeth. and the. movement olil the. pawl ti() such as to advance the ratchet-wheel one twentieth of a revolution during each reciprocation of Aits teeth.

the movable head 30. Diametrically opposed to each other are two notches (3() cut into the periphery ot the wheel (55 between (3T is a similar ratchet-wheel provided with the same number ot teeth and with ditnnetrically disposed notches (t3. These teeth and notches are in alinenient with the pawl surface. (52 and are engaged thereby under certain conditions. Thisl ratchet-wheel is also mounted loosely upon shaft lill. Another ratchet-wheel like those above described is shown a (3S) in alinement with the pawl surface itil. This one is also provided with twenty teeth and two notchesl TO. but. unlike the othersT rigidly atlxed to the sl att 'l. as. tor example. b v moans of a pin Tl. T2 is still another ratchetwheel having, like thc others. twenty teeth. This one. is in alinenient with the pawl surface (il, but instead ot' beingl mounted loosely upon shaft 33,

to the hub ot the gear t).

l: will now point out the operation of this mechanism. As the pawl t3() is reciprocated in the manner previously described` it will cause the ratchet-wheel (S5 to be advanced step by step. This will continue until one of the notches (1(3 comes under the f l. pawl surface ol. when the latter will drop down a sullicient amount to allow the pawl surface (32 to engage one of the teeth of the ratchet-wheel (57. Asthis occurs at ever)` tenth step of advance of the wheel (35, or twice duringeach revolution of the latter, it may be seen that it will take ten revolutions of wheel (35 to cause wheel (37 to make. one. revolution. The notches (i8 in wheel (ST will register with the notches (3(3 in wheel ('15 twice during each revolution of wheel (3T. lllhen this condition is reached, the pawl will drop down tar enough for the pawl surface ($3 to engage one of the teeth oit wheel (t) and-to advance. it one twentieth ot a revolution. As this atlixed to the. shaft 33, its movement will be transmitted to the cylinders 3G and 3T, and its projecting pins 3S will be advanced one step after every one hundred downward movements of the head 30. Therefore, whichever pin on cylinder 3G and pin on cylinder 3T is in actuating position atthe beginning' ot the operation will cause its or their respective punch or punches to be depressed one hundred times and then the next successive. pin or pins will be moved into position to cause the next successive punch or punches to be depressed one lmndred times. et .wf/1w. Buty the ratchet-wheel (if) is also provided with notches T0 which. after each tenth step oit this wheel7 will reir ister with the notches (it and (i8, and this will allow the pawl (30 to drop down until its surface, (i4 engages onoof the teeth of ratchet-wheel T2 and ad 'ances itand the. gear one twentieth of a -revolution. This or allixed thereto.l it aliixed atchet-wheel (tf) isf nism, a greater number of steps.

Willoccur after each one thousand depressions of the head 30, and this movement will he transmitted through gear 45 and shaft 40 to the cylinders 42 and 43. These cylinders carry the pins 44 which actuate the punches in row B so that each of thetion Which I have illustrated I have shown another vmeans for advancin the operation oit the punches in roW C, w iich advance is to take place after each ten thousand depressions of the movable head. In this case a rack 73 is affixed to the arms 32 of the movablehead, and this rack is provided .with a plurality of holes 74, one of which isdirectly above each of the punches in row C.- These holes are preferably numbered (in a manner not shown in the drawings) to facilitate the operation. One or more movable plugs 75 are provided which may be manually inserted in the desired holes, Yand the plugs are designed to depress the desired punch or punches; A handle 76 is atiixed to the end of the rack 73 by means ot' 1which the rack-may be pulled out from the trame so that the plugs 75 may be' easily changed. 77 isaI latch provided for the purpose of holding this rack in place. I have also shown a manually set arrangement for causing the desired punches in row A to be depressed. In this case a slotted bar 80 is bolted across the tace of the arms 32. and adjustable dogs 81 are so arranged that they may be afiixed thereto by means of screws 82 in such position that each dog" will strike and depress one of the pins in row A. 'llhe front or top of the bar 80 may also be calibrated and numbered to facilitato the adjustment of the dogs 81. They may be advanced one step after hundred thousand depressions.

The particular machine herein .illustrated and described has been built for certain requirements and is used as an attachment to a printing press for printing catalogue cards. It is a double machine and can perforate two series of cards simultaneously. It is not my intention` of course. to limit myself to the specific construction herein shown as the requirements for such machines vary so Widely, but it is evident that this invention may be used to automatically change the punches in one set after each depression, or after each ten depressions, or after any desired number oil-depressions. The punches in one row may be changed according to one multiple, and those in another' according t-o each one f another multiple. The size and shape of the punches may he varied at will and may be made to make perforations corresponding with mumbers, as described, or corresponding with letters, or other symbols, if desired. It is only required that the perforations made in the cards or the like may be made in different relative iiiositions thereoinand my invention has provided a simple and compact mechanism by means of which this result may be attained in a more simple manner and with greater accuracy and speed than has been possible with machines heretofore used.
