T 0 all whom it may concern:

Be it known that 1, JOHN T. SOHAAFF, a citizen of the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Verifying Machines, of which the following is a description, reference being bad to the accompanying drawing and to the figures of reference marked thereon.

The invention relates to new and useful improvements in punches for punching holes or verifying punched holes in cards adapted to be used in tabulating machines.

An object of the invention is to provide a machine of the above type with means whereby a card may be shifted on the carrier therefor for the purpose of registration for dressing the A further object of the invention is to provide a machine of the above type with locking means for the key lever so that only one key lever can be depressed at a time. A further object of the invention is to provide the traveling carrier for the card with a hesitation mechanism whereby one or more holes may be punched or verified in a single column before feed of the carrier takes place. A still further obect of the invention is to provide a skip mec anism wherein the skip lifter may be readily removed from the machine when worn and another substituted punch therefor.

A still further. object of the invention is to provide a mechanism which insures the withdrawing of the skip lifter by the idle movement of the carrier, provided said skip lifter is thrown into operatil'eposition by the skip key when the carrier is'release'd by the skip key pletely punched or verified.

A still further object of the invention is to provide a releasing key which releases not only the escap'ement for the carrier but also the hesitation pawl so as to permit free unrestrained movement of the carrier.

A still further object of the invention .is to provide a punching machine'for verifying punched holes in cards whereln when the is depressed at card, a step movement of the carrier may take place, thus indicating that the last hole Specification of Letters Patent.

in the card has been properly punched.

A st ll further object of the invention is to pro'vlde a marginal stop which is independent of the rack bar for controlling the feed of the carrier, which marginal stop may be ad usted throughout a wide range so that holes may be punched or verified in the last column only, if desired, of a card, and also to locate said marginal stop so that it is entirely out of the way of the operator.

A still further. objectof the invention is to provide acover plate independent of the track on which the rollers-to the carrier run for holding the rollers on the track, said cover plate being readily detachable and s1mp1e in construction so that it may be cheaply made. v

These and other objects will in part be ob- VlOllS and will in partbe hereinafter more fully disclosed. i

The invention is directed to a punch which machine, while from certain other aspects said punch may be used for punching the holes in a card which is adapted to be used in a tabulating machine. For the sake of description, have referred to the niachineas a punching machine with of the invention,

When the punch passes through the hole in the card, the bail of the escapement mechanism is depressed so as to feed the carrier forward, which forward movement of the carrier indicates to the roper registration with the field to be punc ed in the card, or so that the punches chine so that the punches may be brought thereof regardless of slight variationsv in v The carrier is the lengths of the cards.

The bail of the escapement mechanism is depressed by akey lever provided there is a hole punched in the card. These key levers are mounted crums and if there is no then the fulcrum yields so card,

that the key lever is not depressed sufliciently to actuate. the.

bail of the escapement mechanism. A skip mechanism including a skip lifter is also provided, which may be used if desired, in connection with a skip bar properly formed so that the operator may skip from one field to another predetermined field without stepping the carrier through all the successive steps between the fields. This skip lifter is automatically retracted nism operates at the beginning of the move ment of the carrier so asto prevent the skip lifter from riding on the edge of the skip bar as the carrier is moved to the right. A hesitation mechanism is also provided which is so constructed that a series of holes may be punched in the same ver-- tion pawl so that the carrier may be quickly moved to a position where the card may be taken therefrom. Means is also propermitting the carrier to move by an escape transversely of the machine.

punching or for verifying the punched hole in the last column of the card, and this mechanism is preferably so constructed as to permit the movement of the card to a position entirely out from underneath the die for the easy and quick release of the card and the insertion of a new card in its place. There are other more or less minor features of the invention which will appear from the detailed description of the mechanism which will now be given.

My improved machine consists of a base or bed plate 1 mounted on supporting legs 2, 2. Overlying the base plate is an upper. framework 3 which includes guide plates 4 and 5 for a series of keys 6 which are indicated in Figures 1, 2 and 9 of the drawings. Associated with each key is a key lever 7. This key lever 7 is fulcrumed at its rearend on pin 8. which extends up into a housing 9 carried by the upper frame portion 3 of the machine. A spring 10 (see Fig. 9) located in the housing bears against a collar 11 on the fulcrum pin 8, and normally presses said pin in a downward direction.

Associated with each key lever is a punch 12. This punch 12 as shown in the drawings, has a reduced end 13 smaller than the opening in the die which is indicated at 14 (see Fig. 9). The punch is. primarily intended for verifying purposes, and the end of the punch is reduced so-as to facilitate its easy passage through the punched hole in the card. The cards to be punched o-r verified are indicated at C in the drawings. The card passes between the die 14 and the stripper bar 15. It is understood, of course, that there are a series of punches and a series of key levers, one for each 14: is shown in plan view in ig. 3, and there is one punch for each opening in the die and therefore, it will be apparent that the punches are arranged in a line extending The punch is raised by means of a spring 16 which bears at its lower end on the stripper bar 15 and at its upper end against a shoulder in the punch. When a key is'depressed, the lever 7 swinging on the the punch. The spring 10 of the fulcrum pin is of greater tension than the spring for the punch. If the card through in alinement with a punch, the

. punch will pass through the hole and the tension on the spring 10 is key lever 7 will move to its normal extreme lower position. If, however, there is no hole in the card underneath the punch, when the punch strikes the card its downward movement will be stopped and the fulcrum pin 8 for the key lever will move upwardly. The so adjusted as to to take place. Directly is the swinging cause this action underneath the keylevers, bail 17 of the escapement will readily be seen punch. The die fulcrum pin 8 will depresshas a hole theremechanism. It that when thekey lever is depressed to its full movement, the swinging bail 17 will be moved downwardly and will cause the carrier to be stepped forward one step. If, however, the key lever does not move downward to any appreciable extent due to the fact that no hole has been punched in the card and the fulcrum pin 8 moves upwardly, then the bail 17 will not be depressed sufficiently to release the escapement mechanism. In verifying the cards, the operator, of course, reads the orig inal record and operates the keys just as though the card were to be punched. If there is a hole properly punched in the card, the bail will be depressed and the carrier will move forward just as though a hole was being punched, and the operator knows that the hole is correctly punched. If, however, a key lever is not depressed by reason of the fact that there is no hole beneath the punch, then there is no forward'movement of the carrier, and the operator knows that the card in the machine has been incorrectly punched.

The key levers are interlocked so that only one key lever can be depressed at a time. This is accomplished by providing a tube 18 which is preferably rectangular in cross section, and in which are formed a series of slots 19, 19 in the top, side and bottom of the tube and in alinement with each'other. Located within the tube are a series of balls 20. The ends of the tube are closed by end blocks 21. This tube is carried by the lower plate 5 beneath the key lever 7 and is held thereon by suitable brackets 22 (see Fig. 9) and 23 (see Fig. 11); Each key lever has a depending locking blade 24. These blades as clearly shown in Fig. 10 are in alinement with the slots 19. The balls are so proportioned that when a key lever is forced downwardly by depressing a key, the locking blade 24 moving between two adjacent balls will crowd the'other balls endwise .of the tube and the tube will be completely filled so that no further sidewise or endwise movement of the balls can take lace in the tube. In Fig. 10,. the key lever a is shown as depressed and the blade 24' has passed throughtheupper slot '19 and in between two adjacent balls. The end balls are now against the end blocks 21 and no further movement can take place of the balls as above noted. 'If the levers 7 b should now be depressed, it would merely come incontact with the balls in the tube and could not pass between the balls as the balls cannot move to permit the blade to get between them. It will therefore be seen that when one key is depressed, no other key can be. depressed to a suflicient extent to bring about any operation until the first key depressed has been released and raises to its normal position.

The cards are moved between the die and the stripper bar by means of a carrier which consists of a rack bar 25 having laterally extending arms 26 and 27. Pivotally carried by the rack bar are rollers-28 and 29. These rollers are grooved to run on a track 30. Also carried'by the arm 26 is a roller 31 (see Fig. 6). The roller 31 runs on the base plate of the machine. These three rollers support the carrier and permit the carrier to be freely moved back and forth on the base plate of the machine. The rollers 28 and 29 are held on the track bar' 30 by means of a cover plate 32. Said cover plate 32 is detachably secured to the track bar by means of screws 33. The. cover plate is bent outwardly as at 38 and thence inwardly as at 34 so as to overlie the rounded heads 35 of the pivots for the rollers 28 and rler in place WhlCll pass through 27.

' ger piece 42 .13 6, that th 29. This cover plate can be made of steel bars by rolling or drawing and cut in suitable lengths and forms a ver simple and cheaply made structure for ho ding the caron themachine.

the right-hand end of the machine projects over the base plate and is, provided with supportingarms 36, 36 each of which has a horizontal groove 37 (see Fig. 8) therein adapted to receive the end edge of the card. These arms extend in part into a recess 38 in the base of the ma-' chine. The arms 36are adjustably secured to the arm 27 by means of screws 39, 39 slots 40, 40 in the arm he other end of the card is adapted to be engaged by a spring member 41 (see Fig; 13). Mounted on the arm 26 is a finby which the carrier may be rea ily moved to the right as viewed in Fig. 3 when the card is positioned for the be-. ginning of the punching or verifying op-' eration. Adjustabl secured to thearm 26 is a bracket 43. Said bracket has a slot through which a screw 44 passes. The spring 41 is carried by this bracket. bracket is slotted at 44' so that spring 41 extends therethrough and lies in front of the bracket. A card is placed in the groove 37 in the arm 36 at one end and the other end of the card is placed against the spring 41,.

his provides a yielding means for dressin the card so as to insure that it will be held against the bottoms of the grooves 37 and thus properly registered if the arms 36,36 are in turn in proper positionfor bringing The arm 27 at about registration. In other words, if the cards vary slightly'in length, the springs will always dress a card 'to the right as In order to insure that a card is properl' registered so that if holes are being punched: these holes will be suitably positioned for operation in a tabulating machine, or if the cards have been punched and are being verie punches will e positioned so as to pass through the punched holes, I have provided the .base of the machine with a The b a 52 mounted on t rier.- In Fig: 14 'rier when moved 'is held in locked is adaptedto slide along registering notch or mark 45, Fig. 1. This notch in the base plate of the machine is so positioned that if the end of the card is in alinement therewit it will be properly registered for operation thereupon. The adjustable arms 36, 36 may be readily shifted in the manner above described for bringing about this registration.

The position of the carrier for'the card is readily indicated to the operator by means of a traveling pointer 46 which is connected, by a suitable cord running over rollers, to the carrier. This pointer travels on a uide bar 47. Associated with the pointer 18 an indicating card 48 which is a duplicate in part ofthe card being punched or verified so that the operator may readily determine from the positionof the pointer the particularpart of the card that is directly beneath the punches in the machine. Attention is called to the fact that this indicator, together with the pointer in the plane or below the plane of the traveling arms of the carrier, and is thus out of the way of the operator.

Marginal sto s are provided the position 0 the carrier at any desired field. For example, it often happens in the punching of a card that considerable data is written on the card and only, the last" few'columns are punched. Sometimes only the last column, and these marginal stops are for the purpose of positioning the carrier quickly so that the first field to be punched or to be verified will be brought infor stopping to operative position relative to the punches. I

y improved marginal stop mechanism consists of a rack bar 49. This rack bar is suitably secured to the bed or base plate of the machine, and as clearly shown inFig. 6, said rack bar is located at some distance beneath the upper surface of the ase .plate of the machine and is well out of the ways One' form of my marginal stop 1s shown in F 1g. 14 and conslsts of a Said placed on the rack bar in proper position so that the blocks he arm 26 of the carrier will strike the faces 53 of said shouldered block and stop the movements of the carof the drawings, the carto. position to engage the marginal stop, is moving in the direction of the arrow; The shouldered member 50 position on the rack bar stirrup 54.

5. Mounted on the swinging member 77 1s a pin 80. While I have shown in Fig. 16 an memberin a clockwise direction about the shaft 76, raise the pin 80 and thus lift the escapement pawl 81. Also carried by the swinging member 77 is an adjustable screw 83. This screw 83 extending down through the member, bears on the arm 84 carried by Said swinging 85 clockwise direction 76 by a spring 86 when remember 85 is moved in a around the shaft leased by the swinging movements of the block 77 The swinging member 85 is provided with a pin 87 which is adapted to engage in a notch 88 in the holding dog 89 of the escapement mechanism. Therefore, when the escapement pawl 81 is raised by the swinging of the bail 17, the holding pawl 89 is dropped. This escapement operates in the usual way. When the holding dog engages the rack bar before the escapement pawl releases the same, and when the holding dog releases the rack bar, then the carrier jumps forward through the action of the spring thereon.

In the form of the invention shown in Fig. 16, I have provided means for yieldingly mounting the escapement pawl 81. The shaft 76 in this form of the invention is mounted at its forward end in a block 90.

d Said block 90 is pivoted at 91 to the bearing plate 92. Said block is formed with an upper flat surface 93 and an overhanging ledge 9 1. A bar spring 95 lies along said flat surface and underneath the ledge as clearly shown in Fig. 16. The other end of-this'bar spring 95 extends beneath a lug 96 carried by the plate 92 and an adjusting screw 97 bearing on the spring, serves as a means for increasing the tension of the spring gThis spring bar 95 tends to turn the block 90in a clockwise direction about itspivotal support and a stop screw 98 limits its movement. This stop screw is carried by a supporting plate 92 and is adjustable and may be locked in adjusted positions.

By shifting the stop-screw 98, the position of the escapement pawl '81 may be varied to take up wear between the parts. Furthermore, when the carrier jumps the action of the propelling spring thereon, the teeth of the rack bar strike the end of the escapement pawl, and this stops It will be yielding mounting of the pawl same vertical column without 25. Said bar 99 is provided noted that the escapement pawl is yieldingly mounted, and therefore this action is cushioned. This greatly reduces the wear and peening effect on the escapement pawl. have referred to this mounting of the escapement pawl as a. modification of the invention for the reason that although this yielding mounting of the pawl is rapidly adaptable to the hesitation mechanism about to be described, I have not shown. in the illustrated embodiment of the in connection with. the hesitation mechanism.

It is often desirable to'punch in a card a series of holes in the-same vertical column, and of course, if a series of holes are punched in the card in the same vertical column, then it is necessary to verify the punching of these holes. I have provided a mechanism whereby a series of keys one after the other may be operated for punching holes in the any feed of the carrier and after the record feed takes place. The same operation also takes place in connection with the verifying of punched holes. This hesitation mechanism consists of a bar 99 which is secured to the rack bar with notches 100, 101 and 102 as shown in Fig. 5 of the drawings. These notches are of different depths and are located so as to correspond with the vertical column in which the series one end of the escapement shaft 76 which is journaled "in plate 105. The pawl is provided with an elongated slot 106 through which the shaft 76 extends. The rear end pg zthe pawl is provided with a segment rack a feed locking dog 109 is pivoted at 110 to a bracket 1 and a spring 112 normally operates to move the pawl toward the rack. ward movement of the pawl is limited by a pin 113 (see Fig. 4).- The feed pawl 108 is provided with a ball 114 at its upper end which fits ina socket in the lever 115 so that the pawl is supported by the lever and at the same time 13 free to swing on the lever. A spring 116 normally moves the pawl toward the segment rack 107 and thepin 113 limits the forward movement of this pawl. The lever 115 is pivoted at 117 to the plate 105. A link 118 is pivoted at 119 to the lever 115. The lower end of this link is pivotally connected to a pin 120 carried by the swinging member 85. The spring 86 is also connected to this pin 120. A spring121 is connected to a projecting lug 122 on the pawl 103 and to a pin on the plate 105. This spring normally pulls the pawl when free, to the position shownin Fig. 4. In this position, the segment rack is moved out of opening 128 in the cover substituted therefor.

range of the feed dog 109.

The pawl 103 runs along the top of the bar 99 and when the carrier reaches the position that the pawl is over one of the notches in the bar 99 then the pawl drops into the notch. When the pawl drops into the notch, then the lifting of the escapement to release the carrier merely lets the carrier move until the end of the pawl 103 comes against the side 7 wall of the notch and the pawl is moved rearwardly'on the escapement shaft 76 to the limit of its movement. The pawl 103 now holds the .carrier from movement against the action of the motor spring. When the key is depressed for punching the hole in the card, it depresses the bail in the usual way. The downward movement of the bail through the devices above referred to permits the actuation of the swinging member 85 and the raising of the pin 120. The up ward movement of the pin 120 through link 118, swings the lever 115 and causes the feed pawl 108 cooperating with the segment rack 107 to move the rear end of the pawl 103 downward one tooth and the locking dog 109 will hold the pawl in this position. The depression of another key for punching or verifying a punched hole in a card again depreses the bail raises the pawl 103 another step. It Wlll readily be seen that holes punched or number of holes verified before the normal feed of the carrier again takes place depends upon the depth of the notches 100, 101 and 102. The bar 99, of course, is shaped so as to correspond with the desired number of holes to bepunched or verified in a given column.

In order that this hesitation mechanism may be rendered ineffective at the will of the operator, I have provided a latch 123 (Fig. 12) pivoted at 124 to the cover plate 125 which it attached to the supporting plate 105 for t I hesitation mechanism. This latch 123 is provided with a. hook end 126. Projecting from the hesitation pawl 103 is a pin 127 which extends through an plate and moves up and down therein. The operator may render the hesitation fia'wl inoperative by holding the release key in depressed position until the latch 123 is depressed and hook 126 is brought into engagement with pin 127. A stop pin-129 limits the swinging movement of the hesitation pawl 103 through the action of the spring 121 when the bar 99 is removed from the machine.

y improved punch is provided with a" skip mechanism which in many of its details, is of the well known construction. I have, however, provided a novel.means mounting the skip lifter 'whereb it ma be readily removed and a new s ip lifter The skipping'mechamsm' comprises a skip bar 130 which is 130 pawl 108 and the locking ,stop for punching provided with a series of notches 131 located at the fieldswhere the carrier is to the punching operation. The skip lifter is indicated at 132 (seeFigures 3 and 8). This skip lifter is provided with a hole 133 at its inner end adapted to take over a pin 134 and rest on a collar 135 secured to the pin. This pin 134 extends through a hole 136 in a toggle link 137 and into a T-bar 138. The pin is riveted in the -T-bar. A pin 139 extends through a hole 140 in the other end of the toggle link 137. The pin 139 is first inserted in the upper bearing by a leaf spring 141, then through the toggle link and then into the lower bearing of said leaf spring. This leaf spring 141 is secured to the frame of the machine by means of a screw 142, and a pin 143.

- The T-lever is provided with a slot 144 which engages over a pin 145. spring pressing on the toggle link tends to buckle the toggle one way or the other and the stop pin 146 engages one wall of the slot 144 or the other and limits the movement of the toggle lever. It will readily be seen that the skip lifter 132 will therefore be held in its retracted position 'where it is inoperative to in any way effect the regular escapement feed of the carrier, or held in its extended position where it becomes effective to modify the action of the escape ment. The end of the skip lifter is held on the pin 134 by a plate 147. This plate 147 slides on a portion of the main frame between two stop pins 148, 148 and is held advanced' over the skip lifter by means of a screw 149. -By backing out the screw 149 the plate may be retracted so that its forward movement uncovers the inner end of the skip lifter, and the skip lifter can then be readily lifted ofi from the pin 134 and thus removed from the machine without in any way disturbing the pivotal support for the toggle link and T-lever. The plate 147 is provided with shoulders which engage the pins 148 to limit its retracted movement. The extreme forward. end of the plate is provided with a socket 150 which is so shape as to become a panel socket for the inner end of the skip lifter when the plate is retracted. Vhen it is desired to insert a new skip lifter, the inner end is placed in the socket, which alines the hole in the skip lifter with the pin 134 and thus it may be readily positioned on the pin. The plate 147 is then forced inwardly covering the pin 134 and holding the skip lifter thereon. ,1

It often occurs in the operation of the machine that the operator will operate the skip key as the last operation in the punching or verifying of a card. This leaves the skip lifter extended forwardly, and during the movement of the carrier toward normal position for punching or verifying a card, the skip lifter would slide alongthe rack bar The leaf placed under skip lifter key,

engages an adjustable screw 169 carried to the frame of the machine arms 154, 154. The arms toward each other by a spring 155. These arms are pivoted respectively at 156, 156. There is a stop pin 157 between the arms and limiting pins 158, 158 outside of the arms. It will readily be seen that if the arm 151 is turned in one direction, the spring controlled arm 154 will be engaged by the pin 153 and yieldingly control the arm 151, while if it is moved in the other direction, the other arm 154 engages the pin 153 and yieldingly controls the arm 151, so that the arm 151 is normally held in an intermediate position, but is tension when moved in either direction from said central position. ounted on the carrier is a pin 159. This in 159 is adapted to engage the inclined le ge 160 at the outer end of the arm 151. When the carrier moves to the left during the succes sive' punching or verifying operations, or when finally released by the skip key, and moved to its extremeleft-hand position, the pin 159 engaging the ledge 160 willswing the arm 151 so 154, 154 are drawn that it may pass. said ledge and the arm 151 will then return to its normal position. On the first part of the movement of the carrier to the right, to bringthe card to initial position for punching or verifying the pin 159 will strike the outer face of the ledge 160 and swing the arm 151 so as to cause the shoulder 161 to engage the end of the T-bar andretract the skip lifter. The skip lifter is thrown into operativgfosition by an X-key (see Fig. 1). This -key when depressed, engages the upwardly projecting arm- 162 carried by a yoke 163. Said yoke has a downwardly projecting arm 164 which engages a laterally projecting arm 165 d of the T-lever 138. Thls swlngs the T-lever so as to project the skiplifter forward,

- bringing shoulder 104 into one of the notches for automatically reand is provided with a pin 153 which projects between the 131. The skip lifter stands normally under the escapement mechthe movementof the out of one of the the escapement pawl of anism and when upon carrier, shoulder 104 rides notches 131 on the upper edge of the bar, it

holds the escapement pawl out of engagement with the rack so that the carrier moves forward until the skip lifterdrops into another notch. The skip lifter is retracted upon'the depressing of any of the numeral keys by means of lug 166 of bail 17, and this lug 166 engages an arm 167 of the key lever 138.

When the yoke 163 is swung by the 168 carried thereby an arm I I v l u i the swinging member 77 and raises the same,

releasing key y wise and is raised through the plate is moved swings rocking mem- N This releases the es- .capement pawl of the escapement mechaand through spring 86 'nism, and brings about the forward feed of the carrier and the action of the skip lifter on the escapement paWl as soon as the carrier moves the skip lifter out of the notch in the skip lifter bar. I

have also provided the machine with a which operates to release the escapement mechanismand the hesitation mechanism. The releasing key is indicated at R and consists of a lever 170 which is adapted to move the slide bar 171. The end 172 of the lever extends down through a slot 173 and isadapted to ing lug 174 on the end of this bar (see i 12 aid bar is provided with a laterally projecting arm 175 which extends into a vertical slot 176 in a slide plate 177 which is mounted .on the inner face of the cover plate 125 (see Fig. 12). This slide bar has a slot 178 which straddles a pin 179 on the cover plate. Said slide plate 177 has an opening or cut-away portion 180 into which extends the pin 127 carried by the hesitation pawl. aid opening has a curved or cam-sha ed wall 181 adapted to engage said pin when to the right as viewed in Fig. 12, and as the pin runs by the curved or cam-shaped wall 181, the hesitation awl will be lifted clear of the notches in the esitation bar. The pin 182 limits the movement of the slide plate 177.

1ts outer end and when the bar is moved from left to right as viewed in Fig. 12, this inclined shoulder runs up on the bottom 184 of the housing in which the bar slides so that the end of the bar is raised when the bar moves from left to right. The housing is provided with a notch185. The end of the skip lifter extends through this notch and always underlies the pawl of the escapemen't mechanism. When the bar moves endthe action of this the escapement pawl is inclined shoulder,

teeth in the rack bar 25.

raised clear of the It will thus be seen that the depression of the releasing key moving the bar 171 to the right as viewed 'in Fig. 12, operates to release both the feed pawl of the escapement mechanism and the pawlof the hesitation mechanism. When the carrier reaches the end of its movement, through the action of the motor spring,the end 186 of the bar 171 engages the lug 187 carried by the arm 27 and this causes the bar 171 to bereturned to normal position releasing both the pawl 1 of the escapement mechanism and the pawl of the hesitation mechanism.

I have provided the base plate at opposite endswith spring or elastic arms 188 and 189 engage a project- 7 The bar 171 is provided with an inclined shoulder 183 near only in the verifying which engage the end of the carrier rack and serve asacushion for stopping the movement of the carrier.

When my punch is used as a verifyin punch, it is essential that the feed of the carrier at least one step, shall occur whenever the punch is depressed for verifying. Prior to my invention, so far as I am aware, no machine has been constructed wherein holes punched in the last column of a card can be verified. As the carrier has reached the end of its movement the punches are brought into register with the last column of the card. I have provided means whereb the carrier may be fed a step after the holes are punched o-r verified in the. last column.

The die 14 is provided with two grooves 190, 190, and the arms 36, 36 areadapted to pass through these grooves so that the carrier may be moved to the left as viewed in Fig. 3, to carry the end of the card to a position entirel to the left of the die 14. When the-last ho e is punched, or the punch is depressed to verify the last punched hole in a card, the escapement is operated in the usual way and the carrier moved to the left which indicates to the operator that the hole has been properly punched and the card is verified. is movement of the card completely to the left of the die also greatly facilitates the placing of the card on the carrier and the removing of the card from the carrier. Rod 139 is secured to the base of the machine by screw 139 and overlies the arm 139 of the carrier end 27. The other end of rod 139 is held in a hole (not shown) in the stripper plate. This rod serves two purposes-it holds the card against buckling and it also guides the arms 36 into the grooves 190 of the die and stripper plate.

From the above it will be apparent. that I have provided a machinewhich, as shown,

is adapted for verifying the punched holes in a card such asiare adapted to be used in a tabulating machine. nism, however, which has been described in detail may be readily used in a punch. for punching the holes in cards. to be punched in cards, of course, the yielding fulcrums for the key levers will be changed and fixed fulcrum points substituted therefor, and punches with cutting ends be substituted for the round end verifying punches. The manner of holding the cards in the carrier, the manner of feeding the carrier, including the skip lifter, mounting and retractin mechanism, the hesitation mechanism and the key locking mechanism are all equally adapted for punching holes as Well as for the punch for should be distinctly ventions claimed are understood that the innot restricted to use punch.

It is obvious that many changes may be made in the details of construction and the Much of the mechaverifying holes, and it' If holes are of the card and holding the arrangement of the parts without departing from the spirit of the invention as set forth in the appended claims.
