GERMAN CORPORATION.

rnnrrnva raauna'rmc momma To all whom it may con/cervix :Be it known that I,' HEINRICH TOLLE, a citizen of Germany, residing at Villingen, Baden, Germany, have invented certain new I and useful Improvements in Printing Tabulating Machines of which the following is a full, clear, and exact description.

This invention relates to a computing machine in which the setting or adjustment 1 of the counters is effected by reci rocating toothed racks. The invention has or its object to provide such counter o crating mechanism with reciprocating rac s, which will be accurate and positive in operation and at the same time present a compact structure. It is necessary for this purpose that the counter operating toothed racks are maintained free from all the projections thereon. In accordance with this invention this result is achieved by actuating the toothed racks for individual computations through the intervention of oscillating latches which are caused to mesh atdiderent phasesof their oscillatory move- 26 ment, so that,'depending on the particular time of j. enmeshment .of the latches the toothed .Ii'acks will move through a longer or shorter path and will thereby impart to the counters a correspondingly larger or 30 smaller movement of "rotation.

For printingisums and for resetting the counter wheel io zero a special arrangement is which; taking intoconsideration the compactness of the entire structure, must be of such nature that. the actuating mechanism for the toothed racks will take up no more space in a transverse direction than the toothed racks. improved machine this condition is met by 40 providing a system of pusher bars or rods in extension of the setting toothed racks for actuating said racks for the sum printing operation and for re-seating the counters to zero position. Fig. 1 is a sectional view of the complete machine taken just inside one of the side plates thereof. i

Fig. 2 is a similar sectional view with parts omitted in order to more clearly show the operation of the adding and tabulating parts of the machine.

Fig. 3' is a sectional view showing the operating parts utilized in taking sub-totals or intermediate totals.

Fig. 4 is a sectional view showing the operation of the parts when the machine is to be cleared after a total has been taken.

Fi s. 5 and 6 are enlarged detail views showing the latch mechanism for the racks respectively in latched and unlatched position. I

Fig. 6 shows the unlatched osition of the parts just after a rack has con set by the latching devices.

lt willdoe understood that the machine can include an number of accumulatin sections. in which case these sections wi be identical in construction. For each sec tion of the machine there are three operating' ke s designated respectively 29, 29 and 29. (ey 29 is utilized or setting the machine in operative con ition tor str'aigrht adding. Key 29" is a s'ub-total key. which isdepressed at the end of the addition of items from agroup of cardsto cause the machine to take a sub-total and then go on accumulating without clearing the counter. Key 29, on the other hand, is a total key. It is depressed at the end of the addition of a roup of cards to cause the machine to print a total and causethe accumulator to be'cleared. Inasmuch as the accumulating mechanism on the difierent sections is identical one section alone will be described, it that duplicate mechanism will be provided for the other accumulating sections dr in case the machine includes only one accumulating section only one set of parts will be needed.

The tabulating machine comprises two side plates and the adding mechanism is built in therebctween. This is shown in Fig. 1 of the drawings, one of the side plates being removed for the purpose. The adding mechanism is arranged on the side plate 1 shown in -the drawings and comprises a stationary plate 2anda movable slide 3 thereon.

tens-counting. mechanism control and 'oonsists mainly of the control levers 4, release lever 5, arresting lever 6, and the lifting lever 7. The counter rollers 8 and their actuTiEing wheels 9 and 10, as well as the release lever 11. the safety locking lever 12 are arranged on the slide 3. The latter by the lever 13 through the intervention of the projection or abutment 14, when a dog member 16 resiliently secured to the lever 13 is set by the key 29 (Fig. 2} through the rod 15, in such manner that in its upward movement the dog member 16 will carr alon jection 14 on the sli e 3. n addition to the lever 13 there is provided another lever 18 (F ig. 4) similar in its function to the lever 13 but controlled by a differently shaped cam disc 19 and consequently operating at different times from the lever 13 to raise and lower th slide 3 The dog .member 18' of the lever 18 is actuated from a special bar or rod 20 throu h the intervention ofa key-129 (Fig. 4). in addition to the rods or bars 15 and 20, other barsor rods 23 and 24 operate in the same guide bearings 21 and 22 (Figs. 1 and 3). Bar or rod 23 (Fig. 1) carries at its right a roll 26 which may drop into a notch formed in a crank disc 27. When this notch isvreached bar or rod 23 is moved to the right under-the influence of spring 28 and the locking hook 28 having a fork and pin coupling therewith releases the key levers 29, 29, Q The p reference character 29 refers generally to These are given further dethe key. levers. tail reference letters 29, 29", or 29: depending. upon their function. The key levers are however maintained in thedepressed position by means 30,30; 30", 30' rotating simultaneously about a shaft 25. In view of the simultaneou-s. ere on of the locking members 30,

30", etc. the depression of a new key releases all previously depressed keys. The bar 24 (Fig. 3) carries a pin Maud-transmit's the pressure of the lrcy 29", through the intervention of a lever 32 and'rod 33, toa

bell crank lcver 34 which is adapted to engage a pin in the slide 3 and to raise the adding mechanism. In this position the wheel 10 engages a toothed bar or rack 35, which by means of a pin 36 sets the t pe segments 52, which latter may be 'loc ed prior to printing by a lever 37. A special arm on this lever places a colored ribbon in front of the types, by means of a rod 38. while said types are being set. The lever 37 is actuated through the intervention of the intermediate lever 39 from the bell crank lever 40, which is in turn operated by the specially formed cam disc 62. The toothed bar or rack receives its movemcnt from the reciprocatingcarriage 41,1the

latter being: actuated from the cam disc 42 through the intervention of the large bell crank -lc\'er 43. The coupling of the carriage 4i and the toothed rack 35 is eflected by the multi-toolhed locking hook 44 which is adapted to be actuated by magnets 47 through the intervention of levers 45 and 46 to engage the teeth of the rack 35. In extended alignment with the rack 35 is arranged a rod 48 under the influence of a spring 49 and adaptcdto be held back by an with it the proof beveled locking members,

arresting or locking lever 50, until released by the and 29". This movement of the lever 50 is transmitted (by a through. setting rod 51 'passing along side of the rods- 48 and 35) to a type segment similar to and adjacent the type segments 52, which segment then causes the ;'printing of' an indication of the manner of use for which the machine was set. In view of the different distances between the points of engagement of the rods depression of predetermined keys 29 53 and 54 and the centre of rotation of the operative movementto, their original positions by the carria e 41 through the aid of the lever 55 rotata 1y mounted 'on'the carriage 4i and moving in-an additional path by the sliding of its inclined surface on the in The rods or levers 5T, 58, 59, 60 serve to withdraw after each excitation of themagnets 47 such structures as may cling to tliemagnets. .This rod or lever system is actuated from a'pin on the lever 13.

The operation of the tabulating machine in its various individual uses is as follows:

a 1% Adding and ta bulatz'ng (Fig. 2).

who. the key 29'- is-depressed the rod 15 1 moves to the right. The (10 member 16 is is positioned under the projectiono'r abutment 14 of the thereby swung upward an counter mechanism slide 3. If the machine is now operated the two cam discs 42 and 61 will rotate in the direction indicated -by the arrows, on a ratio of one to one. In this manner the roll of the bell crank lever 43 is moved downwardly and the carriage 41 is thereby moved from left to right. At the same time a contact is closed in known manner (see Hollerith Patent No. 945,236. dated January. 4, 1910) in the'card'feeding arrangemcntfi which contact is held closed while.a card is passing through the machine. When a countingposition or perforation is reached in. the card the circuit oi one of the magnets 4iv will be completed (as in Hollerith) and the carriage 41 coupied with one ofthe rack, bars 35. Each magnet for a corresponding cardcolumn is held energized while counting takes place as is usual. The movement of the armature of the magnet 47 is transmitted through the levers 46; 45 to the coupling member 44 which engages the rack 35 and carries the same along through a path the extent of which depends on the position of the countingpoint or perforation in the card. Dur ing this forward movement the rack 35 effects the setting of the type segment 5'2,

After the carriage 41 has completed its movement to the right, the lever 37 which has to this moment been kept out by the levers 39 and and by the cam disc 62 (Fig. 3), is now released for a short period. The type segment 52 is thereby centralized to effect proper alignment of the type, and the colored ribbon rod 38 moves the colored ribbon to the left-in Fig. 1 to the type. .At.

this moment the type is printed in known manner on a passing paper sheet. In the meantime also the cam disc 61 (Fig. 2) has begun to lift the lever 13 and has thereby caused the engagement of the intermediate wheel 10 and the toothed rack 35, while the roll of the bell crank lever was passing over a'concentric portion of the cam 42, thereby maintaining the rhcks 35 at rest for printing. This movement of the lever 13 is tra nsmltted through the system of rods or levers 60, 59, 58,57 to the lever and the coupling between the members 44 and 35 is thereby released. This step is taken to 'ensure that no armature clings to an electromagnet after'the circuit of the magnets is broken. The carriage 41 now moves idly back a certain distance under the action of the rising part ofthe cam disc 42, such disumn.

taiice corres onding to the complementarv number of t e perforation in the card colber 44 therebyengages the projection on the rack 35 and returns the rack to its zero osition. In this manner the same number 1s transferred to the adding roll 8. If now the number 9 is exceeded, the tens-arrangement is brought into operation under the influence of the release'levers 11 and 5. and its operation is completed upon the return of the adding mechanism to rest.

The-machine is thus returned to its original position and begins addition and tabulation of the next card column. A

If a contact arrangement is usedwhich in place of the time contact, such as assumed above, establishes a momentary contact, i. e., 1

one which differentiates the.numbcrs not by the durationof the current impulses but by closing the contacts at different times. and in which the duration of individual contacts may be less than. the" time necessary for effecting the registry of a unit in the counter mechanism, such modification is taken care of'by the provision of arresting or looking levers 69 (Figs. 5, 6), the arrange ment being such that the coupling between the rack3 5and carriage 41 is maintained until the latter has completed its operative movement.

The ope ition is then. as follows: If the coupling member is actuated by the magnet 47 through the aid of the intermediate lever 45, the latter is prevented from dropping by the lever 69 (Fig. 5), until the carriage 41 has completed its movement to the right.

The shoulder of the coupling mem- At that moment the pin 70 secured't0 the .carriage 41 releases the lever 45 (Fig. 6),

and the arrangement is contact;

The machine has added a row. of numbers and is restrained by a stop cam or has been brought to rest by the completion of thecom uting operation. Upon depression of the ey 29" the rod 24 is moved to the right. This movement on the one hand, couples the adding mechanism with the toothed rack 35, and, on the other hand, it looks the levers 45 through the intervention of the upper nose of the lever 32, thereby reventing the engagement of the cou lngs 4'4 through accidental current i mpu sea. The depression of the key also causes the/lever 50 to move outwardly and therehyto release the spring bars 48. The latter now follows the left toright movement of the carriage 41 caused .by the rotation of the cam disc 42. The racks 35 are next broughtto the po si'tionnvith their projection 63 bearmg on the couplings 44 and they rotate the adding wheels 10 backwards until thenoses prepared for a new thereof lie against locking hooks,.i. e., until the adding mechanism is brought to the zero 7 thereby brings the previous sum back to the I adding mechanism. in view of the slidirlg of the inclined face of the lever 55 on the pin 56, the pin 64 moves through a longer path than the carriage 41 and there- .hv releases the bars 48 from the rack 35.

The machine remains at rest. in this position and 'is ready to perform other functions.

3. To talizing and zeroizing of the sou rater mechanism Fig.4.

If it is desired to print the total at the end of a column and to cancel the cumin the addmg mechanism, so that the latter may be ready to perform a new addition, the operation of the machineis similar to that for taking intermediate sums, except that the coupling between the toothed rack and the counter roll isreleased when the latter is in the zero osition. In this operation, steps must be talzen to prevent the toothed racks, which are'suddenly released and which are under the influence of the spring 49, from accumulating the complementary numbers of the sum. The timely release of the engagementhetween the toothed rack 35 and the toothed wheel 10 is effected not by the release of the keysproper, as in the print ng of intermediate sums. but, as in the adding operation, the key 29' causes the rod 20 to move to the'right and the lever'lS is pushed under the post 17, whereby, in the continued operation of the machine, the cam disc 19 immediately causes the engagement of the toothed wheel 10 and rack which engagement is maintained until the carriage 41 has completed its movement to therig'ht. By the displacement of the rod 20 the lever 57 1S pressed against the lower. ro'ection of the lever 45 holding the latter ee As the'toothed racks 35, which are under the influence of thespring 49 and which until now have been restrained by the toothed wheels 10 (which latter have rotated until their noses rest on the locking book 12),
