Figs. 7 and 8 show sections taken respectively on lines 7 7 and 8 8 of Figa.

Fig. 9 is a face view of the print and non-print locking plate. i

In said co-pending application, there is shown a printing tabulator which is adapted to be actuated by perforated cards, which in their passage through the machine operate elements for setting up type commensurate with the designations on the card and actuate an accumulating mechanism for accumulating therein the data recorded on the card perforations whereby the total accumulated data may be computed and then printed by the printing elements of the machine. f

The embodiment comprises, as shown herein a lower framel (Fig. 1) in which the main driving` shaft Q, is mounted, a card feeding mechanism, and a card analyzing mechanism; and an upper frame 5, in which the accumulating and printing mechanism are mounted.

The cards to be analyzed are disposed in a suitable receptacle and are fed by a card picker mounted at the bottom of such receptacle to the feed rollers 7, from which the card is fed between they die plate 8 and guide plate 9 in which position the several designations on the card register with the pins 10 of the vertical reciprocatable pin boX 1l, which pin box is raised after a card is positioned between such plates 8 and 9 and the pins 10 which find perfor-ations in the card being analyzed pass upward therethrough and engage extension pins 12 which, in turn, will actuate registering stops. After the card has been so analyzed by the pins 10, it willbe discharged into a suitable receptacle.

Power is transmitted from the main drive Shaft 2 to a shaft 17 by means of a transmission shaft 18. Y

The shaft 17 is provided with a plurality ofi cams from which are operated'4 as explained in the cti-pending application, the various mechanisms of the tabulating machine 19, of which it suffices here to say that thesev operate the type segments 20 (Fig. so that the type 21 will be positioned to print. items in accordance with the setting by the cards of the pins 1() and 12; and print the resulting totals, upon a sheet of paper brought against the type bythe printing carriage now to be described.

The printing carriage, designated genen ally by reference numeral 28 (Figs. 2, 3 and. 4)' is located on the rear of the printer taliulator base, to the rear of the tabulating machine 19.

The carriage 28 which consists of mechanism for controlling the movement of the paper rolls andv printing on the salne is mounted between twoV plates 47 which are tiedk together by means of tie-rods 48 and Said carriage 28 is carried at each end on an L-shaped support member 35 which slides in a slot 34 in bracket 31 and also has a roller 36 on the end of its horizontal armwhich roller moves in anI opening 37 formed in bracket 29. On the upper end of the vertical portion 38 of said member 35` is a connecting shaft 39. Mounted on the shaft 89, between said members 38, are Vtwo* levers 87 which are also mounted on a shaft- 89'carried in bracket 31. These levers 87 serve in the manner to be later described to give a reciprocating motion to the carriage so that it can be moved against the type sectors 2l in order t0 print.

Another pair of supports 42 which are approximatelyv Lshaped, are connected near the upper ends of their vertical arms to shaft between the'two levers 87, and have forward extending arms 44 curved to come directly under the tie-rod 48 so that they support the tie-rod and the carriage. The supports. 42 are mounted, at the point where the vertical and horizontal arms moet, on the shaft 40..

Two forwardly extending. plates 45 are secured in slots in the shaft 39 and at their forward ends support a carriage rail 46 sothat when shaft 89 is reciprocated by 50 are connected with they carriage- 28` by rods 49 and It will thusKV be seenthat the carriage 28 ispi-votally suspended at its rear on rail 46 and in front is supported by the contact of# rod 48 with arms 44.

In the operation of the machine it is sometimes desirable to shift the carriage longitudinally relatively to the type sector units, so that the printing columns may occupy various desired positions upon the sheet of paper. Means for accomplishing this will now be described:

The forward" edge of the uprights 38 (Fig. of the members 35 are provided with inwardly turned perforated ears 61v (Fig. 5) carrying supportingl studs 62 on which is slidably mounted the'locatingy bar 64' provided with elongatel slots 65 receiving said studs 62, said bar 64 being alsov provided with a plurality ofholes 66 large enough to receive the head ofthe locating stud 67 fixed on the locating; bracket 686x061 to the bracket shafts 69` (Fig. 6) connecting the.

end plates 47. n y

rPhe stud 67 carried by bracket 68 is locked in positionA (see Fig'. by means of` a locking pla-te 70 provided with key slots 71 each having a large end 72 thru"V which the head of the stud 67 is adapted to pass and with small ends 74 adaptedtov form shoulders to engage under theheads. of said studs whereby the stud is locked in osition by means of Ya spring 75 tensione 'between the upright 38 and the angular manipulatingv end 76"bent outwardly from said locking plate. c

Y The locking; plate 76 isheld inproper position by meanscf theguide plate 79 and 80,.the guide plate 79 being secured to one of said ears 61 and engaging over the looking plate, thev guide plateY 80 beingsecured to the manipulating end 76 ofthe locking plate and providedl with a slot 81 receiving a screw 82 secured to the adjacent ear 61.

To change the position; ot thefcarriage the locking plate 70 is pushed `over toallow pin 67 to swing free of holes 71 and 66* after which the carriage 28'is swung tip-around rail 46 and then is moved along rail 46 until it reaches the desired location when the pin Y 67 is reinserted in'a new hole 66 and locked in place as desired.

The printing` is accomplished by the forward movement of the paper supporting mechanism which movement brings the paper against type 21 of the type sectors.

This is accomplished by means of the upper and lower carriage actuating levers 87 and 88.(Fig. 3)' pivoted on the lever shaft S9 carried by the brackets 31. The upper and lower actuating levers are both pivotall'y mounted on said shaft 89 and when in printing position are locked togethei` as will be explained, and are oscillated by means of the engagement of Jthe cam roller 90 engaging in the cam groove 91 of the printing cam 92 carried on the cam shaft 17. The actuating levers give one complete cycle of oscillation epee for every revolution of the cam shaft 11.

The locking above referred to is accomplished by means of locking cones 95 which are shown in unlocked position in Fig. a and must be moved to the right of said figure to lock said upper and lower levers against relative movement. rlhese cones engage in, and when locked, hold in alinement the openings 98 and 99 of said upper and lower levers, and are carried on the cone supporting shaft y100 yieldably drawn to unlocked position by means of the tension spring 101 secured between the end of said shaft and a cross piece 102 (F ig. 3) disposed across the opening 104 in the bracket 31. The vopening 10d. is large enough for the insertion of the cone shaft and cones when assembling the machine. These cones may be moved to locking position by means of the bell crank lever 105 fulcrumed on the base of the machine and provided at its upper end with spaced ea s 106 engaging a transverse pin 10T in the cone supporting "shaft 100. This lever is actuated by means of a link 108 pivoted at its lower end to said lever 1 5, and at its upper end to the locking lever 110 (Figs. 2 and 3) fulcrumed intermediately as at 111 on the cam shaft bracket 29. The locking lever 110 terminates in a manipulating end 112 (Figs. 2 and 9) received in a slot 114 of the locking platev 115, said slot being provided at `itsupper and lower parts with shoulderforming recesses 116 and 11. in which said manipulating end may be locked to retain said locking cones in either locked or unlocked position. When lock lever 110 is moved into locking position7 lever 87 will be moved by a movement of lever 88 and thereby the printing` carriage will be moved and the items set up by type segments AJ1 will be printed.

Now will be described the means for supporting the paper on the carriage.

On the paper roller shaft 60 journaledin the end plates'fl? (Figs. 3 posedva plurality of paper engaging means or rollers 118 each provided with afboss 119 8). These bosses are Y held spaced apart by means of spacing bushings 120 (Fig. 7). Between adjacent pairs of the paper rollers 118 and loosely engaging said bushings are disposed platen support brackand 6) are disets 121 held against rotation by `means of the bracket shaft 122 6) passing thru holes in the lugs 123 on the upper part of said brackets and mounted in plates 417. Said brackets are held in spaced relation by means of sleeves 124C (Fig. 8) carried on said shaft 122. The lower part of each platen support bracket carries a forward projection 125 on which is secured as by means of a-screw 126, the platen support 127 having a recess in its forward end in which is carried the elastic platen block 128 of rubber or other suitable material which forms a paper backing means for the paper when it is pressed against the type.

The bushings 120 hold the paper rollers out of frictional contact with the platen brackets.Y The bushings and the paper rollers and all the parts rotatable on the paper roller shaft 60 are caused to rotate with said shaft by means of frictional engagement with each other brought about by the clamping of the screw 129 (Fig. 3) on said shaft.

.Between each adjacent pair of paper rollers are the upper and lower inner paper ls 190 and 131 (Fig. T) which form a continuation of the cylindrical surface of the paper rollers. These shields have angular extensions 13e, each extension having inwardly turned ears 185 each provided with an opening' receiving the bracket shaft 122.

'The upper inner shield 130 is pivotally sup- Ad rod by said ears, being perto move pivotally because of the i upper face 130, whereby access may i may be omitted if desired.

y surrounding or housing the lower shields 131 and the lower part of the paper rollers 118 are the outer paper shields 1 irovirlcd with edge flanges 13S on which a -rmed turned ears provided with receiving the bracket shafts 69 3 and 7 These outer shields cow.: with the lower` inner shields 131 to 'E for the paper 140 on which the are to be printed. the outer being ontinued upwardly in front Y aver r llersll, whereby are formed l/isl: (F ig. 7) between which the the type sectors pass when the pressed against them by means of laten b ocks 12S.

The lenenGv pushes up on end pieces 152 locatedl at each end of levers 14.7,. thereby swinging rollers 148 ont of the position shown in dotted, lines in Fig. 6. The shaft 1:57 to which levers 156 are fastened is carried; between end plates 4r and. has directlymnnected toit a levei` 158 which is manually operated to release the pressure on the rollers as described, then lever 158 is released, toward movement ofl this lever is limited. by projecting portion 169 otplate r7.1 (seeFig'.

efter each nun'iberyisprinted by the type ot the: type sectors, it is necessary to feed the paper upwardly one or more spaces` rlihisl feeding accomplished by` means oit' engagement of the teeth of the feed ratchet 161, mounted on the shaft by a two armed feed pawl 152 (Fig. 3) pivotally mounted on the feed pawl lever 164 ful-v crumed intermediately as on the stud shaft 1.65 and driven by the link 166, which in turn isidriven by the drive lever 167 mounted on the lever shaft 168, said shaft being actua-tedby the ae eating arm 159 fixed on said shaft and adapted to come into contact with and be moved by the abutment shaft 17.0 carried on the abutment shaft bracket 17.1y pivotally mounted on plates 32 which are suspended between brackets 29 and 31. The brackets 171 are limited in their rearward.V movement by the engagement with the tie plates 32 of a lug 174 laterally turned at the rear edge of said abutment shaft brackets, and is yieldably held at its rear* ward: limit of movement by a spring 175 tensioned between said"` lug 174` and a lug on there-ai.' part of the Vshaft plate 32.

When the carriage is moved forwardly toward the type .sectors the free end 'face 176'of the actuating arm 169 engages and pushes back the abutment shaft 170 against the action of the spring 175 until said end face clears said shaft and permits the` shaft and its bracket to be snapped back by the spring 175 until stopped by the shoulder 172.

After the printing has taken place and the carriage moved rearwardly, the abutment shaft 17() is engaged by the lower side the actuating arm 169 whereby said arm and drive lever 167 are raised thus rocking the pawl lever .1G/1+; and loweringl the pawl 1.62,. whirh turns the ratchet A161 and moves paper 14()V aheadv oneA space.

The feeding mechanism is returned to position. by means of a spring 185 tensioned between. the end. plate 47 and a perforated ear on the upper part'o'f the inner end. of the arm 167. Y

F or nen'iovingl or feeding paper entirely independently of the feeding mechanism,4 I. provide the paper feed gear 189 fixed on the paper feed shaft 6() and engaged bythe idler gear 19t) rotatably mountedvv on the end plate4 t7 the idler. gear being in turn engaged by the knob gear 191 'fixed on the stud shaft 165 rotatably mounted in the end plate 47 and carrying knurled knob 192 by which said shaft and gears may be manually rotated.

While the paper is being fed and during; the time of printing, it is desirable that it be firmly held against the platensL 128. This is accomplished by means of a clamping. mechanism con'iprising a clamp bar 193 (Fig. 3). carried between the outer ends of the clamping levers 19st provided with intermediate longitudinal slotsA 195 loosely receiving the paper feed shaft whereby the paper clamp bar is adapted to move toward and from the paper. rollers 118 aswell as to pivot in relation` to said rollers. The

inner ends of the clamp levers are provided with small pins 196 received in. longitudinal slots-197 in the lower ends of the spring levers 198 intermediately fulcrumed on the end plates 4.7 and dra-wn by a spring 199 strained between the upper end of the spring levers 198 andy the upper part of end plates 47, whereby the clamp lever 194 is yieldably draw u downwardly and the clampbar 193fis yieldably pressed against the paper and the paper pressed against the paper rolls 11.8.

This yieldable engagement maintains duringl the printing and feeding ofthe paper, but after feeding has taken place, as above described, thereleasing pin 200 mounted on the cam bracket sli aft 201 comes into contact .iiitlr the abutment shaft 17() andforces the cam bracket shaft and the cam bracket 202 to rock rearwardly whereupon the cam edge 293 forces outwardly the pin 196 and therewith the'lever 191 aud-bar 193and also rocks said lever in a direction clockwise on Fig. 3 whereupon the bar 193` is moved downwards ly over theV paper and later takesa. freshgrip upon the paper when the clamping lever is released by the cam on the next forward movementof the carriage and moves downwardly under the action of the spring*` 199.- I

'Ihe upper. part of. the cam` brackets 202 are each provided with an outwardly projecting ribbon feed arm 204 (Fig. 3)` for operating the feed mechanism of the ribbon spools ofthe ribbon 205 (Figi.v 4)*grbut as these form no part of the inventionA claimed herein they are not, now further described.

lilheu a total. is printed itis desirable to show some visual signal to indicate that the number printed is a total. This is accomplished by shitting the carriage to. the left pivotally connected to the rear end of the horizontal lever 244 (Fig. 3) intermediately pivoted on a pin 245 in a lug 246 on the base of the machine. The forward end of said horizontal lever is pivotally connected to the rear end ot' the total shift lever 252.

VVhenthe total pin 258 engages in the appropriate groove, after being manually released said pin is shifted to the right and a total is set up on the type 21 as eX- plained in said copending application and the upper end of the lever 242 is shifted to the left whereupon the locating bar 64. is

ymoved to the left on thepin 62 in the slot 65, thus causing the printing to take place a slight distance to the right of the column.

ylVhen by means'of the lever 110 the carriage has been set to a non-printing position so that the items accumulated and set up by the type 21 are not printed, it is still desirable' that the totals themselves be print-` ed. In order to accomplish this printing automatically, there is provided the automatic printing lock lever 257 (Fig. 4) pivotally mounted on the bracket 258 fixed to the shaft 89 tlie upper end of which lever engages in a notch 260 the lowerend engaging` a transverse pin 261 in the printing lock shaft 100.

lhen the carriage is shifted to the left, the bar 64 is moved therewith and carries the upperend of the lever 257 to the left whereupon the lower part of said lever, said printing lock shaft and the cones 95 are moved tothe left thus locking together the upper and lower printing levers 87 and 88 and effecting the printing.

From the foregoing, the operation of the printing carriage will be easily understood. Paper is inserted in the rear opening` between the outer shields 137 and the inner lower paper shields 131, and the paper' rolls 118 turned b v means of theknob 192 until the part on which it is desired first to print are opposite the platen blocks 128. If desired, the locking plate is unlocked and the carriage adjusted on the carriage rail and thev carriage relocked.

rPhe locking lever 1.10 is set in locked r unlocked position depending upon whether it is desired that the items be printed or not. y

The tabulating machine is then started in operation as explained in thesaid copending application and the type is set and the accumulators accumulate. If the locking lever 1s .set in locked position the cams 92 cause the printing levers vand the carriage to re- K ciprocate and the printing is effected.

llfhen a total is taken the carriage is moved to theleft just before the printing by means of the total signal lever 241 engaging in the notch 240 of the locatingbar. If the locking lever 110 has not been set in printing position, the automatic levers 257 also cause the cones to look the printing lev rs and print totals when the totals are set up and printed.
