TABULATlNG-MACHINE.

SPEQIFIGA'IION forming part of Letters Patent No. 694,955, dated March 11, 1902.

Application filed November 1 9, 1900. Serial No. 36,951. (No model.l

To (tZZ Lt/"7007. 7 zit may concern:

Be it known that I, DORE E. FELT, a citizen of the United States residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tabulating-liiachines, of which the following is a specification.

This invention is an improvement in computing tabulating-machines adapted to print parallel columns of numbers side by side upon a more or less wide sheet of paper as distinguished from the narrow ribbon paper heretofore commonly employed. Ileretofore these machines have been provided with alarms controlled by the paper and acting to give a signal when the printing reaches the bottom of the sheet, and I have shown such alarms in mylai'ents Nos. 628,176 and 64%,287. Alarms, however, often fail of their object, as the operators do not always heed them and do not always hear them, and it therefore the quently happens that the operator continues to go through the operation of setting up and printing numbers after the alarm is given and after the bottom of the sheet has moved beyond the feed-rolls. In machines of this kind this causes serious trouble, as the numbers set up after the sheet has passed through the rolls are added by the nu meral-wheels and printed one on top of another at the same point upon the paper and must be subtracted before proceeding with the next column,or the entire column must be printed and added over again.

To avoid this trouble is the main object of the present invention, and I have succeeded in avoiding it, as well as in improving the n1achinein other respects,byprovidingthe printing mechanism, and also the adding mechanism, with means whereby both may be absolutely looked as soon as the last line has been recorded, and all further printing (except of totals) and adding be prevented prior to the shifting of the sheet forthenext column. The action of these locking means is controlled by the paper being printed. 13y thus locking the printing and adding mechanisms I avoid all danger of the adding of numbers which are not also properly recorded, and the operator is relieved of all care upon that subject, as the machine automatically looks when the printing approaches the bottom of the paper, and this branch of my invention consisis in the combination, with the printing and adding mechanisms of a tabnlating-n1achine, of means for locking such mechanisms automatically when a full column has been printed.

Another feature of the invention relates to the construction of the devices whereby the paper thus controls the locking devices. As heretofore constructed the paper-roll has been provided with a single annular groove, into which a spring-pressed finger or wire is entered when not held from entering by the paper, and this finger in the act of entering the groove sets in operation the alarm mechanism. In order to insure action by this finger when the bottom of the sheet moves beyond it, the spring actuating it must have a fair amount of strength, and in my use of the device I found that sometimes the spring caused snfficient friction upon the paper to tear it, especially when the finger nears the bottom of the sheet, and the finger almost always caused an objectionable crease in the paper. These evils I now remedy by employing a series of fingers spaced apart so as to act upon the paper at different points, thereby distributing the pressure of the spring upon the paper through a series of separated planes, instead of a single plane, as heretofore. I thus obviate both the tearing and creasing of the paper, without in any degree detracting from the efficiency or centainty of action of the fingers.

The invention also embraces several other features of novelty which are fully explained in the description given below and pointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure l is a plan view of a tabulator provided with my present improvements, partly broken away. Fig. 2 is a horizontal longitudinal section of the paper-carriage, partly broken away. Fig. 3 shows the rocking bar carrying the springfingers pressing upon the paper and controlling the locking mechanism. Fig. l is a perspective of the device for transmitting motion from the paper-controlled device to the look ing mechanism. Fig. 5 shows the columin S is a horizontal section.

tion. Figs. 10 and 11 are partial vertical sections. Fig. 12 is a partial horizontal section, Fig. 13 is a vertical longitudinal section of the complete tabulator, showing both the printing mechanism and the adding mechanism. Figs. 14 and 15 are detail views, the latter beingin perspective.

In said drawings, 15 represents the keys; 16, the surrounding-frame; 17, the numeralwheels; '18, the answer-printing-plunger; 19, the operating-lever, whereby the ordinary printing, the adding, and the line-spacing are done; 20, the column-spacing and paper-reversing lever; 200, the type-segments 21, the ink-ribbon spools; 22, :the upper paper-roll and 23 the lowerpaper-roll, and 24 is the upper guide and 25 the lower guide, between which the paper X is inserted. The'rolls and guides are supported in a laterally-movable paper-carriage composed of bars 47 and 470 and end connections 47 1. 5 v The main cam, operated by lever-19 and causing many of the operations of the machine not necessary to be described here, is shown at 26. It operates the paper-feed rolls by means of a .bent lever 27, pivoted to the cam and operating the crank-arm 28, fast on the shaft 29, which I call the main or line shaft. Shaft 29 also carries another crankarm 30, to the outer end of which a pawl 31 is pivoted. This pawl engages a ratchet- Wheel 32, fast on the sleeve 83,- hereinafter mentioned, and encircling the angular shaft 33, which carries a pinion 34, meshing with the pinion 35, loose on the shaft 36 of the feedroll 23 and operating said roll through the medium of a clutch consisting of the disk 37, sliding on the shaft and having a laterallyprojecting pin 38and a disk 39, attached to pinion 35, and having a series of openings 40, into which said pin is adapted to enter. The dis'k37 forms one side of an annnlarly-grooved slide 41 and is constantly impelled toward pinion by a spring 42, confined on the shaft between the slide and the pinion 43, through which and the pinion 44 on the shaft 45 of the upper feed-roll said upper feed-roll-is driven. The slide 41 is moved at will, so as to disengage the pin 38 from disk 39" by the elbowlever 46, pivoted upon the spacing-bar 47, the end 48 of said lever entering the groove of the slide, as plainly shown at Figs. 2 and 8. Normally this clutch is closed, as .in Fig. 2, but

i is shown disengaged at Fig. 8 in order to better disclose the construction. Pin 38 passes through a block 370, fastened to shaft 36 and interposed between the disks 37 and 39. By means of lever46 the operator opens I the clutch whenever desired and while pressline-space at each actuation.

The locking of the printing and adding mechanisms when the bottom of the paper is reached in the tabulating operations is eifected as follows: As shown clearly in Figs. 6 and 7, the edge 49 of cam 26 is serrated and adaptder and acts to lifta bar 58, which'I call the finger-bar and which has a limited up-anddown swinging movement, being pivoted at its ends'59 in the carriage ends 471, the ends 59 being bent away from the plane of the bar, as seen at Fig. 3. This bar carries a series of fingers or feelers 60, projecting forward from it and registering with slots 61, formed in the paper-guides 25 and 24. These fingers are located close under guide 25 with their points extending through guide 25 and when the lever 56 is permitted to lift=the bar 58 the fingers move from the position of Fig. 6 to that of Fig. 7. In the former they project into the path of the paper,'but are prevented from en-v tering guide 24 by the paper, and in the latter figure the paper having passed beyond 1 them they rise and enter the slots in guide 24.

The fingers are employed in such number as may be desirable to prevent such friction upon any part ofthe paper as might rupture, m'utilate, or crease it.

It will be seen from what is above written that the cam will become looked as soon as the bottom edge of the paper has passed the fingers and the fingers are'permitted to rise in obedience to spring 53. ."lhe paper thus controls the fingers and through them it also controls the locking of the cam, and while thus locked neither the printing mechanism or the adding mechanism, in so far as they receive motion from lever 19 or cam 26, can be operated, and consequently the operator is absolutely prevented from either printing or adding numbers after a full column has been recorded. Thefingers 60 are depressed when inserting the paper by providing rollreleasing lever46 with a pin 62, which when the lever is operated bears against the inclined end 63 of an arm 64, attached rigidly to the finger-bar 58 and rocks the bar, thereby carrying the fingers downward and admit:

ting the paper freely. The annular grooves 65 in the roll 23 give room to the fingers 6O 7 Figs. 6 and S. This mechanism consists of the pinion 71 on shaft 33, the train of gears 72, 73, 7st, and 75, and the toothed segment 76, having internal teeth meshing with gear 75. The segment is mounted loosely on shaft 77, and the hand-lever 20 is mounted on the same shaft and carries a stud 78, engaging a shouldcr or projection 79 on hub of the segment. The regular line-feeding movements given the paper will, through the mechanism de scribe( carry the segment step by step from the position of Fi 6, in which its projecting lug 80 is close under the upper stop 81, to or toward its lowermost position, (shown at 7, in which the lug 80 is almost in contact with the lower stop 82,) the extent of the segments movement depending on the number of lines printed, and when the column is completed the operator in order to return the paper vertically has only to depress lever 20. He thereby, through the engagement of stud 78 with the shoulder 79, raises the segment to the upper position again, and in so doingim parts a backward rotation to the gears and through them to the feed-rolls exactly equal in extent to the aggregate of the feeding movements received while the tab ulating was being done, and consequently the top of the sheet will be returned to the plane in which the printing was started. 1Vl1ile l have shown stops 81 and 82 in position to engage the lug 80 on segment 76 at the end of the up and the downstrokes of the segment, I do not rely on those stops regularly to arrest the segment.

As already explained, the locking of the cam 26 by the lever 50 as the printing nears the bottom of the sheet acts to prevent any further feeding movement of the paper-rolls, so that no further downward impulses will be given to the segment, and this occurs before the lug S0 strikes stop 82, and in the case of the up movement of the segment I provide another stop, located near the ratchet-shaft 33 and consisting of a pin 115, carried upon the side of pinion 71, and a stop 116, consisting of a projection formed on the inner side of a vertical plate 117 and located where it may intercept pin 115 at or shortly prior to contact by lug 80 with stop 81. The pinion 71 is thus arrested and with it the train of reversing mechanism. By thus arresting the reversing mechanism at the point where it first receives power I avoid the evils which would be caused by lost motion in the parts between stop 81 and said pinion 71 and insure the stopping of the paper-rolls when they are reversed at the exact point at which they were positioned at the time of starting the printing. The engagement between pinion 71 and gear 72, which, with its companion gears 73, 74, and 75 is supported upon a stationary part of the machine, such as the side plate 160, is maintained during the lateral movements of the paper-carriage by mounting pinion 71 upon a sleeve 83, fitted to and turning with shaft 33 and held against moving with the shaft in the longitudinal movements of the latter by a stationary bearing 84;, encircling the sleeve between the ratchet-wheel32 and an outstanding rim or flange 85, so that pinion 71 and gear "2 are never out of mesh. The bearing 8% is attached to plate 100, and the sleeve may be fitted to the shaft at one end only, as seen at 830.

For shifting the paper laterally in columnspacing I employ the following mechanism and operate it simultaneously with the To" versing ofthe sheet, so that by means of the same motor device both movements may be accomplished. The reversingdever 20 is connected by a bent link 95, pivoted to the lever at 96 to the short arm of an elbow-lever 97 by a universal joint, and lever 97is pivoted stationarily at 98 and carries upon its long arm a pivoted pusher 99, adapted to engage the notches 100 in the spacing bar 47. The pusher is normally held out of engagement with bar 17 by rest 101, but is urged into engagement as soon as it moves cit the rest by spring 102. The notches 100 are spaced apart to agree with the width of the columnspaces, and each actuation of the reversing-lever 20 the movement given thereby to the link and elbow-lever carries the pusher off the rest and moves it far enough beyond the rest to shift the spacing-bar and with it the paper-carriage a column-space to the left. A stop 103 maybe secured to the top of plate 160, where it will come in contact with the short arm of lever 97 and limit the movement in one direction; butits use is optional. To prevent overthrow of the carriage in the shifting movements, an elbow-shaped latch 101 is employed and connected to elbow-lever 97 by a link 105. The link is freely joined to the lever and is slotted at 106, where it joins the upper arm of the latch. The normal position of the latch is shown at Fig. 2, and by reason of the slot 100 it is not forced down into acting relation with bar 4C7 until the shifting movement is almost complete. It enters notches 107, located between notches 100 and which have their abrupt side facing in the opposite direction from theabrupt sides of notches 100. To hold the carriage stationary between the shifting operations and also to insure uniformity in its positioning, I employ a spring pressed dollyroll 10S, entering notches 107. The roll is carried in the end of a pivoted bar 109, and the bar is pressed downward at all times by a spring 110, joined at one end to the vertical part of latch 101 and at the other end to a bent lever 111, employing the pivot 112 of the bar as a fulcrum andbearing on a pin 113, inserted in the bar. The notches 107 are cut from side to side of the bar, while notches 100 are out only part way through, and consequently. the dolly roll 108 cannot enter the latter. The dolly-roll does not effect an absolute lock of the carriage, but is easily forced to yield whenever it is desired to move the carriage by hand.

The machine may be used with ribbon or roll paper, as well as sheet-paper, by providing it with a support for the shaft of the pa- 1 per-roll in proper relation to the paper-guides and paper-feed rolls, substantially as shown in my Patent No. 614,287, and by providing it also with the throw-011 or disconnecting mechanism now to be described. At 86 is a hand-lever, which I term an interlocking lever. This lever is pivoted upon a stationary pivot 87. and carries at its lower end a U shaped piece 88, which sets over pinion 71 without interfering in anyway with the latters' rotation, (see Fig. 9,) and by means of this lever said pinion is shifted on the sleeve to a slight extent sufficient to draw the laterally-extending pin 89, carried by the pinion, from the opening in rim 85, with which the pin is adapted to be brought intoregister, When the pinion is locked tothe sleeve by pin 89, it compels the reversing-mechanism to move with it at each actuation of the paperfeeid rolls, and thus carry segment 76 down ward, so that the feed-rolls will be reversed and return the paper to its startin'gpoint when the segment is returned by lever 20, as already described; but when the pinion is free from rim 85 the pinion does not turn with the sleeve in the line-spacing, and consequently the'reversin g mechanism remains idle, so that the ribbon-paper'instead of the sheet-paper can then be used to receive the tabulations. By-means of the lever 86-thereversing mechanism is readily thrown into or out of gear, as desired, in an instant of time, so that the machine is practically always ready for use with either sheet or roll paper.

It is very essential that when the reversing mechanism is reconnected to the feeding-shaft 33 the same teethshall come in mesh that were in mesh at the time of disconnccting, because if different teeth are brought-in mesh in reconnecting the stop-pin may not be in proper position relative to stop'116 at the end of the reversing operation, or the ratchet 32 might be stopped in some position in which its dolly-roll 130 would rest on top of a tooth instead of entering between adjacent teeth. To avoid any possibility of't'his kind, I provide means whereby the connecting and dis connectingcan take place only when the parts are in a certain position. To this end, the vertical plate 117, already mentioned, is pivoted at its lower end on a stationary pivot 118 and is provided with an arm 119, positioned so it will be engaged by the pin 120 on the inner face of segment 76'just before the segment reaches its upper position. The plate also is provided with an opening 121, encircling the hub of the pinion 71, but larger than the hub,

so as to permit a slight edgewise movement by the plate upon its pivot 118. The plate is positioned close to thepinion, so that said pin 115 will strike it and prevent the'shifting of the pinion, except-when the single small opening 122, located close under the stop 116, and the pin 115 are brought into register one with the other. This opening is adapted to receive the pin, and thus to permit the pinion to be shifted toward plate 117 by lever 86in effecting the disconnection of the reversing mechanism. A springl23'constantly draws the plate in a direction which carries the opening 122 outof the orbit of pin 115, so that no opportunityis affordedto shift pinion 71, except when the segment overcomes said spring 123 and forces the plate oversufliciently to allow the pin to enter the opening. It will also be noted from Fig. 8 that pinion 71 has no intermediate position, but is either locked to the sleeve by pin 89 or is held against rotation by the entrance of pin 115 within opening 122 of plate 117 and that it can only be shifted from one of these positions to the other when the opening in the rim of the sleeve and the opening in the plate are both in register with their respective pins. It will also be observed that the slight movement allowed plate 117 is suflicient to carry the opening 122 into and out of the orbit of pin 115. The construction described permits the disconnecting'and reconnecting of the reversing mechanism only when the segment 76, and consequently all the gears and the pin 115, are in one particular position and the dolly-roll 130 is seated between two of the teeth in ratchet 32, thus insuring that the identical teeth of all the intermeshing parts which were in mesh at the time the disconnecting took place are, again brought into mesh and continue at all times,while connected to bear identically the same relation to one another. The plate 117 is steadied and guided at the top by the notched pin 121. From this paragraph'the operation of stop 116 and pin 115 will be more fully understood. With the pin-stop over the pinand the pin 120 against the under side of the arm 119 no obstacle exists to the feeding of the paper, because the pinion 71 is free to move in the direction in which it moves when the paper is fed upward, and such movement carries segment 76 and its pin 120 downward away from arm 119 and also carries pin 115 away from stop 116. The feeding of pin 120 downward allows spring 123 to act and move plate 117, so as to carry stop 116 out of the orbit of pin 115. The dollyroll 130 is supported in a swinging arm 131, supported upon a stationary pin 132 and is normally urged toward the ratchet-wheel by spring 133 through the medium of a bent lever 134, employing pin 132 as a fulcrum and exerting its power. upon the pin 135, inserted in arm 131. The dolly-roll is forced away from the ratchet whenever the reversing-lever is actuated by means of the cam-lever 136, fast on shaft 77 and acting on the pin 137, secured in the dolly-carrying arm131, the lever 136 having an inclined surface 138,

adapted to move the dolly-arm in the direction which carries the dolly away from its acting position. The spring 139,0ne end of which acts on the cam-lever and the other end of which is secured to a stationary stud 140, acts to return the cam-lever and with it shaft 77 and the parts carried by it to their normal positions after each reversing operation.

The machine is adapted to be used with sheet-paper of a predetermined lengthsay, eighteen inches-but any shorter length may be used. If paperlonger than the maximum length for which the machine is intended be inserted, the fingers (50 would be prevented from acting before the lug 80 reaches the stop 82, because the longer paper at that time would still-be interposed between the fingers and the upper guide 24, and consequently in such cases nolocking action by lever 50 would be caused and the operator would be at liberty to continue setting up and printing hum-- bers, although no feed of the paper takes place after lug S0 is in actual contact with stop 82. The result just described might also be caused by faulty positioning of a sheet of the prescribed lengththat is to say, so that its bottom edge instead of passing entirely beyond the fingers at the time of the printing of the last number remains over them, so as to prevent their operating. I therefore provide other means than those already described for causing the locking of the cam when the fingers are prevented from operating, as above set forth. To this end lever 50 is provided with a projecting lug 141, as seen at Figs. 6 and 7, and the segment is provided with a contact-piece 142, so positioned that when the segmentapproaches its lowermost position the contact-piece will en-v gage said lug and force lever 50 against the cam and thus lock the cam in the same manner as when it is caused to be locked by means of the fingers 60. The contact-piece 142 is made yielding, being pivoted at 1&3 atone end and pressed outward at its other end by the spring let. A pin 145 limits the action of the sprin The connecting-rod 54; isjoincd to the lever 50 by a yielding joint construct ed as seen at Figs. 6 and 7. The end of the rod is bentat right angles and is inserted in a vertical slot 145 in the lever, and a spring 14.7 secured to the lever bears at one of its ends upon the bent end of the rod. This flexibility in the connection avoids any danger of versing levers are located this shaft is provided with a segment-shaped crank 150, the normal position of whichis illustrated at Fig.

11 and. in which it rests against a step 151, secured in the side plate 161. To this crank are attached two slotted links 152 and 155, the former connecting the crank 150 with the crank on the main shaft 29, receiving motion from the operating-lever, and the latter connecting the crank 150 to the end of the lever 155, by which the printing of the totals is caused. Link 152 is slotted to permit crank 151 to move through the major portion of its stroke before actuating the printing shaft, and the link 153 is slotted to permit lever 155 to move partially through its stroke before operating the same shaft. The totalprinting lever is also joined by a slotted link 157 to a crank 156, fast on the extension 200 of shaft 29 and which is permitted to turn in dependently of shaft 29, being like shaft L of Patent No. 644,287 in that regard and also in its purpose and function. A stop 158 on crank 15-l limits the movement of crank 156 downward. \Vith the construction set forth the actuating of shaft 29 by the operating-lever gives no motion to the total-printing lever, although all the other parts mentioned in this paragraph are moved, and, on the other hand, the actuatingof the total-printing lever gives little or no motion to shaft 29.

For changing the machine from single-linespace to double-line-spaceprinting and back from the latter to the former I employ the following devices: At is a lever stationarily pivoted at 01 and having its lower end enlarged on one side, as seen at 2, Fig. 8. As shown, the lever is not acting, and consequently the pawl 31 will move the ratchet to the extent of two teeth at each actuation and the printing will be doublespaced; but if the lever 90 be shifted, so as to carry its side enlargement close up to the ratchet, the pawl, which is wider than the ratchet, will ride over the enlargement before it engages the ratchet, and consequently cannot engage the latter until its down movement is half made, and conseqnentlyitimpartsonlyaone-toothmovement to the ratchet and the printing will be single-spaced.

The locking-lever 50 is released from cam 26 whenever the total-printing lever 155 is operated by an arm 170, extending downwardly from the shaft 171, to which lever 155 is fast, and the pin 172 on lever 50, which encoun ters arm 170. This will be understood best from Fig. 11. The same figure also shows a bar 173, actuated by a stud 174: on shaft 171 and serving to tip very slightly the hammer housing, of which a portion is shown at 175.

The keys are each provided with an offset or bend 176 on their stems, adapted to engage the segment-levers 177, the offsets being graduated in position, so that each key will be able to impart to the lever the proper amount of movement. Each of the levers is provided with teeth which mesh with the pinions 17S upon the same shaft with the numeral-wheels, and each of said pinions actuates one of the numeral-wheels. The carrying-leverisshown at179. 1hel :eysareadapted to be set in advance of the adding and printing, and to this end they are provided with shoulders 180, adapted to be engaged by spring-catches 1S1, carried on frame 182, sustained on cranks 183, one of said cranks being on the shaft 184:, provided with a second crank 185, the upper end of which carries a pin 186, working in a slot 187 in the main cam 26. The catches are released from the keys by a horizontally-moving frame 188, mounted The downward movementon the frame 182. of frames 182 and 188 takes place when the hand-lever 19 is operated and carries any key which may have beenpreviously set; down I for each denomination embraced in the ma-- I denomination together with carrying devices,

The releasing movement of frame 188 is caused by means not shown, but whichmay be seen in my Patent No. 568,021 of September 22, 1896.

644,287 of February 27, 1900. The paper e n ters the machine between the guides 2a and 25, is fed by rolls 22 and 23, and guided'up- \vard by guides 208.
