HAND PUNCH Application l led June 13,

This invention relates to card perforating -machines adapted for use in the perforated- In. this systemthe principal machines are the tabulating machine which senses the data contained on thev card in the form of perforations and lists such data Or accumulates the same or both and subsequently produces a total of the data accumulated; a sorting machine into which indiscriminately mixed cards are placed and the machine sorts the cards into the desired groups; and a perforating machine by which the dat-a is applied to the cards in the form of perforations. The cards are divided into fields or columns, each column containing several index points one or more of which points willI be perforated toI represent the desired data or other indication. The present invention relates to a machine for producing these perforations. In the system at present the perforating machines are usually designed to be placed'upon a desk or table to be O erated. While the machines are capable o being conveniently moved about from place to place they a5 ield use Where the operator must carry the machine with him.

The object of ythe present invention is to provide a very small, light and compact p rforating machine which the operator may conveniently carry about.

Such a machine may be used in connection with the reading of gas,

electric and other service meters. .Thus in-` stead of the operator bringing` in at the end of each day a Written list of the meters inspected and the data taken therefrom, he places a card in the machine and applies the data relating to each meter and its reading to the card in the form of perforations, at the end of his tour he delivers these cards to the oilice and they are run through the other machines of the system which automatically produce the desired report sheets in `printed form.

Referring to the drawings:

Figure is a section through the machine taken on line 8-8 of Figure 1 tol` show the operating handles and associated parts.

Figure 9 is a partial top plan view of the vpunch selecting handle1'04,'\vhich is inoperable in a vertical plane but operable in a horizontal plane with, stud 103 as its axis. A pointer 105- is fixedly mounted on the handle 104, and cooperates with a tix-ed plate 110 Vhaving thereon a series of numbers, 0 to -12 and the letter E. The numbers on said plate correspond to the numbers on thecard 112. Yhen the index points to the position E no hole is to be perforated in the card, but the card will 0n the next operation escape and present the next column in perforatiiig position.

Then the punch selecting handle 104 is swung about, the pointer 105 will indicate on the plate `110 which number will be punched on the card. The selectionis effected by means of -a gear sector 106 (Fig. 1) lixedly mounted onthe handle 104 at its pivotal point.

This sector actuates a wheel 108 by means of a gear 107 fixedly mounted thereon.

About the periphery of said wheel 108 are radial pins 113, which engage a series of holes 114 in the punch selecting band 115 which also rides around an idler wheel 116 and is also supported thereby.

An arm 120 (Figs. 3 and 8) depending from the band 115 has a slot 121 through which a stud 122 passes into block 118. When the band 115 is moved to a position indicated by the pointer 105, said band will slide the block 118 along a bar 119, by means of the depending arm 120, until said block 118 is under a punch 123 corresponding to the number to be perforated.

When the pointer 105 indicates E the block 118 will be in a position where it cannot actuate a punch. The bar 119 has on each end a trunnion 124 (Fig.l 2) by means of which the bar is pivoted between arm 125 and arm 126 rigidly mounted on shaft 127.

The punch operating handle 128 is pivotally mounted on handle 104 by means of stud 129. This handle 128 moves in a horizontal plane with handle 104, but is operable vertically with stud 129 as its axis. coil spring 130 acts to keep the two handles normally apart.

Mounted on the punch operating handle and extending inwardly is a lever 131 having a slot 132 which is so constructed as to be coaxial with stud 103 and engages a stud 133 in a lever 134 extending from arm 125.

The slot being coaxial with the stud 103 will therefore engage the'stud 133 in any position assumed by the punch selecting handle 104, see Fig. 8.

When the punch operating handle 128 is compressed towards the punch selecting l handle 104, lever 131 cooperating with lever 134 will cause the shaft 127 to rock. The

arms

125 and 126 will lift bar 119 causing block 118 thereon to force' the punch 123 through the card 112, the block 118 being free to move upwards with respect to band 115 due to slot 121 in 'the depending arm 120 (see Figs. 3 and 7).

To prevent the punch selecting handle 104 from being swung about while the punch operating handle 128 is in operation and in so doing cause the punch to strip or otherwise damage the mechanism, a locking lever 135 is provided and is pivotally mounted on a bracket 136 on the side of the punch selecting arm 104 (see Figs. 4 and 5). On the under side of the indicator plate 110 are notches 140, there being one notch under each character. A spring 138 extending from a stud 137 on t-he locking lever 135 to a terminal 139 on the bracket 136, tends to force said locking lever into the notches 140. This is normally prevented by a`tab 143 (Figs. 2 and 4) proJecting from the lever 131 lupon which the lower end of the locking lever normally rests. When the punch operating handle 128 is compressed the tab 143 will move away from the locking lever which will follow said tab 143 until it engages a notch. The return of the handle 128 will not remove the locking lever from the cutuuntil .it is almost restored to its normal position thereby allowing the punches to be fully restored before handle 104 can be operated.

To aline the various parts in correct relation to each other a ball detent 141 in the punch selecting handle 104 cooperates with the notches 140, locating said handle in its proper position (Figs. 4 and 5). This will cause all parts to be properly located for punching.

Fastened to the bar 119 and extending upward are arms 142 which support the punch restoring comb 144. The arms are also used to prevent the bar 119 from turning by pass- `ing through two guiding slots in the lower punch guide 145. The teeth 146 of the punch restoring comb 144 extend between lthe punches 123 and restore said punches by depressing the collars 147 fixed on the punches.

The punches are also guided by the upper A punch guide 148 above which, allowing an intervening space for the card, is the die plate 149. Between the upper punchguide 148 and the die plate 149 is the front card lguide 150 and rear card` guide`151V (see Fig. 2). i

The card carrying device consists of the card carrying bar 152 having on itsunder side a rack 153. On the right end an arm 154 extends forward and acts as a stop for the card, the card being held in place by a slotted tab 258 as shown in Figs. 1, 6 and 9.- The projecting member 155 is used for shift-ing the card carrying device. On the left end of the card carrying bar 152 is a similarly constructed arm 156 which also has a projection 157 which can be used to shift the card carrying device.

Attached to the right arm 154 is a draw string 158 extending from a standard type# writer spring drum 159 mounted ona bracket 71. A pawl 170 engaging the ratchet 160 holds the adjusted tension of the spring drum in the well known manner. The bracket 171 also serves as a bearing support for shaft 127 and extends between the inside walls of the upper portion 101 of the case, see Fig. 6. Bracket 172 (Fig. 8) serves 'as `a rear bearing for shaft 1 27.

Fixedly mounted on shaft 127 is an arm 173 (Figs. 9 and 11) which engages an angular cam surface 174 of the pawl actuating lever 175 which is pivotally mounted on bracket 176. A spring extending between stud 177 and tab 178 holds the'pawl actuating lever 175 against the arm 173. A finger 17 8a forming part of the lever 17 5 extends through.

a hole 280 in the holding pawl 179 which is pivot'ally mounted on thefupper portionofthe case 101. l

The sliding pawl`tl80-'is-pivotally; mounted on the upper portion-of the case-101by means- 5 ofv aV stud 197 passing throughthe elongated slot 184 and isheld in engagement with rack;

153 by means fofspring, 18lbetween stud 182 on the'sliding pawl 180,andstud183.l The;k sliding pawl '180` has zan .extending arm 185V which'projects underthe; finger 17 8?y of the: pawl actuating lever 175. y L s. f When shaft 127 is actuatedby means hereinbefore described, arm` 173 acting against arm 185 of the sliding pawl 180 causing said a0, 153 and by means of slot 184 slide forward a lever 188 lever 188-on1ts upper part extends under they pawl to lift outl of engagement withv rack to engage the next tooth ofthe rack 153.

' When the shaft 127 returns to normal position the holding pawl 179 will be disenga ed from the rack 153 and the rack will go orl 25 Ward until the sliding pawl 180 stopsfit on the following tooth, seeFigs. 9and 11.

To shift the Icard its full length a bell crank 186, pivoted on theqlower portion 102 of the case, has an arm 187 which engages pivoted on bracket 176'.l The arm 1185 of the sliding pawl. A spring 190 between

studs

177 and 189 holds the lever 188 against the arm 187 ofthe bell cranky-186.

- When the bell crank'186 is actuated to the left it will cause lever 188 to lift the sliding pawl 180 out ofv enI agement with rack' 153. The rack will then die free to move forward until a block 191 stops against'the guide 192 whichythe card carrying device is guided by. f 1When'it is desired to shift the card to perforate in a certain columna series of numbers 192a (F igs.. 1 and 9) on the card'carry- (ing bar 152 corresponding to the column numbers on theca'rd indicate through a sight hole `193 whenthe desired column is in its proper position for perforating.

A pocket 194 (Figspl and-6) is provided in the upper portion of the case 101 into which covered by a cover 195 held `down by acoil spring 196. f This holds the punchings in the `pocket 194 until they can be disposed of.

,f Briey summarizing, a card` is 'inserted between guides'152 .and 153 being advancedl tilllits right end abuts arm 154. Theleft end of the lcard is forced-over the upper/edge of arm 156 and is located thereby. Either projecting
