SPECIFICATION forming part of Letters Patent No. 780,272, dated January 1'7, 1905.

Application filed March 30, 1901. Serial No. 53,669.

To all whom, mfr/,y @Qn/cern:

Be it known that I, Donn 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-Machines, of which the following is a specification.

This invention relates to `tabulating machines.

In the use of these machines it is sometimes desirable to tabulate amounts upon a less number of lines, counting vertically, than the sheet is adapted to hold; and my object in the invention has been to provide the machine with means whereby the operator may be informed when he has tabulated any predetermined number of amounts. In other words, I have devised and applied to a tabulatingmachine suitable mechanism adapted to be set in advance of the tabulating and which when any predetermined number of lines, either the entire number which the sheet will hold or any less number, have been tabulated the machine will automatically lock, so that no further amounts can be printed until the lock is released.

The invention is an improvement upon the machine shown in my application, Serial No. 36,951, filed November 19, 1900, and since patented in Patent N o. 694,955, dated March 1I, 1902, in which I show means for locking the machine when the bottom of the paper is reached, the locking mechanism being controlled by the paper itself; but in the present invention I do not rely upon the paper for this purpose, though the machine may embody both the mechanism of my said application and that of the present invention also.

The nature of the present improvements will be fully understood from the specification given below and is also fully illustrated in the accompanying drawings, in which- Figures 1 and 2 are longitudinal vertical sections of a tabulating-machine embodying my invention, the first showing the parts in normal position; and the latter being' partly broken away and showing the parts in their locked position. Fig. 3 is a detail cross-section. Fig. I is a section on the line I 4; of

Fig. 3. Fig. 5 is a partial longitudinal vertical section, and Fig. 6 is a longitudinal vertical section showing more especially the printing mechanism of the machine. Fig. 7 is a partial horizontal section showing more especially the laterally-movable paper-carriage.

In said drawings, l5 represents the keys; I6, the surrounding frame; 17, the shaft on which the numeral-wheels 18 are supported; 19, the pinion actuating one of the numeralwheels; 20, the segmental lever meshing with said pinion and also lioined to the type-segment 21 by a link 22 in such manner as to position such segment when it (the lever) is depressed. The carrying-leverof the numeral-wheel next adjacent to the wheel shown appears at 23. The keys are each provided with an offset or bend 25 on its stem adapted to engage the lever 20, and the offsets are graduated in position, so that each key will be able to impart the proper amount of movement to the lever. The keys are made the medium of depressing the levers 20, and to this end each key-stem has a shoulder 26, adapted to be engaged by a springcatch 27, carried by a frame 23, when the key is depressed or set by the linger of the operator. The frame 28 is united to an operatingframe 29 by links 30, and a bodily downward movement is imparted to frame 29 by cranks 3l on shafts 32, one of said shafts having a crank 33, the upper end of which carries a pin 34:, working in a slot 35 in the main cam 36, operated by the printing and adding hand-lever 37. The downward movement of

frames

28 and 29 caused when the hand-lever is operated carries any key which may have been set downward with the frames, and such key imparts a movement to its segment-lever proportioned to the power of the key, and the segment-lever in turn actuates its corresponding numeral-wheel to a proportionate extent and positions the typesegment to which it is attached with the figure corresponding to the key at the printing'- center. It will be understood that there is a series of nine keys for each denomination embraced in the machine and that such keys are duphcates of the ones shown; also that there is a separate numeral-wheel and segment-lever for each denomination, together with carrying devices for all the wheels except the lowest. The keys are released from the catches by a horizontal movement of frame 28, imparted to it at the conclusion of the printing operation by means not shown, but which may be seen in my Patent No. 568,021, of September 22, 1896.

The paper (seen at 38) is impressed upon the type by spring-actuated hammers 39, of which there is one for each denomination and which are normally held out of action by detents 40, but are released from the detents by the tailpieces 41, actuated in part by the segment-levers 20 and in part by a swinging cross-bar 42 and thehammer-releasing frames 43. The action of the parts 39 to 43 is fully set forth in my Patent No 644,287, of February 27, 1900. The paper enters the machine between the

guides

44 and 45, is fed by

rolls

46 and 47, and is guided upward by guide 48.

The present machine also embodies mechanism for returning the paper to its starting position after the completion of a vertical column and simultaneously shifting the paper laterally in column-spacing, and this returning and shifting mechanism may be patterned after the designs shown in either of my Patents No. 628,176 or No. 644,287. The mechanism now shown for this purpose is substantially like that of Patent No. 644,287 and consists of the pinion 50, which corresponds to the pinion C of the patent and is actuated in the line-spacing' movements of the paper-rolls, the train of

gears

51, 52, 53, and 54, the segment 55, actuated by gear 54 andsupported on shaft 56, and the hand-lever 57, mounted on said shaft and having a stud 58 engaging the shoulder 59 on the hub of segment 55. The segment also carries a projection 60, which encounters stationary stops at both limits of its path, the upper stop being' shown at 61 and the lower one at 62.

The locking mechanism is preferably similar to that of my pending application, Serial No. 36,951, filed November 19, 1900, in which the edge 63 of cam 36 is serrated and is engaged by the serrated end 64 of a lever 65, pivoted at 66 and having a spring' 67 urging itinto engagement with the cam. This spring is controlled by the means set forth in my said application and consisting of a series of feelers 68, arranged under the path of the paper and pressed upward against the same by power from spring 67. The connections between the feelers and the spring consist of the lever 65, the connecting-wire 69, the lever 70, pivoted at 71 and acting upwardly on the bar 72, supporting the series of feelers. The bar 72 is supported and moves with the laterallymovable paper carriage, the longitudinal members whereof are shown at 73 and 74 (the full details of a desirable construction of which carriage are fully set forth in my said Patent No. 644,287) and which also support the paper rolls and guides, as will be understood. The feelers are prevented from moving upward by the paper; but as soon as the bottom of the paper passes them they move upward and allow the spring 67 to throw the lever 65 into engagement with the cam, thereby arresting both the adding and the printing mechanisms of the machine.

In order to insure the locking of the cam 36 by lever 65 when any predetermined number of lines have been printed, I employ the following mechanism: At is a rotatable dial the face of which is divided by indicating-marks into spaces which ordinarily will equal in number the number of lines which the paper is capable of receiving. The dial illustrated has ninety-four spaces, but may have any desired number, and it is provided with a stop-pin 81, adapted to encounter a stationary pointer 82 and prevent it making a complete rotation. This dial is mounted on a sleeve 83, loosely encircling a shaft 84, but capable of being locked thereto by tightening the nut 85, so as to force the sleeve againsta collar 86, rigid on the shaft. The sleeve is also rigid and preferably integral with a pinion 87, meshing with a pinion 88 on the shaft 89, which is the shaft carrying the

gears

53 and 54 of the paper-returning mechanism. Pinion 88 is loose upon shaft 89, but is compelled to turn with the latter whenever the laterally-projecting pin 90, carried by the pinion, engages the arm 91, radiating from collar 92 on shaft 89. Shaft 89 is turned by

gears

53 and 54, but communicates no motion to gear 87 or shaft 84 until the pin 90 and arm 91 engage. The sleeve 83 is normally locked to shaft 84, but is released whenever it is desired to change the relation between pin 90 and arm 91, so that their engagement may take place earlier or later. This adjustment is effected by turning the dial until the desired mark thereon is brought in front of the pointer, as seen at Fig. 5, where the dial is set at the second mark, indicating' that the engagement shall take place immediately after the second forward feeding movement of the paper. Obviously the dial might be set at 94 or any smaller number. l/Vhen the shaft 84 is thus actuated by the engagement of pin 90 and arm 91, it gives a swinging movement to an arm 93, rigidly attached to its farther end, and this arm is connected by a bar 94 to an upward projection 95 on lever 65. The bar 94 is slotted at the end connected to projection 95, and the arm 93 is also slotted at the end joined to the bar, as shown, and at this latter junction a spring 96 is employed tending to force the bar in a direction corresponding to that in which it is moved by arm 93. The actuation of shaft 84 through these devices moves lever 65 into locking position with the main cam, and thus arrests the printing and adding, both of which IOO are brought about by the movement of said cam, and as such actuation takes place whenever any predetermined number of lines has been printed it will be seen that I am able by setting the dial at the desired number to bring about the absolute locking of the machine whenever that number of amounts has been tabulated and added in any column. The spring 96 renders the impact of the lever 65 with the main cam a yielding impact, thereby avoiding' danger to those parts, without, however, impairing the locking-action. The dial is located at the side of the machine where the total-printing lever is usually located. This lever is shown at 97 in Fig. 5, together with some of the parts actuated by it. The bar 94 is connected to the arm 93 bythe pin 98, fast in the bar, and to arm 95 by pin 99, fastin the arm.

I have shown in the drawings a number of features which have no bearing upon the present invention, among' which may be mentioned the interlocking lever 100, angular shaft 101, through which the feed-rolls are actuated by means not shown, the movable plate 102, having an opening 103 for the pin 104, the spring 105, the cushioning contact 106, the bent link 107, connecting lever 57 to the pivoted lever 108, carrying the pusher 109 for shifting the carriage in column-spacing. The construction and operation of all these parts is fully set forth in my said -application Serial N o. 36,951.

It will be understood that the shaft 84 will be rocked back after each actuation by the return of arm 93 and that shaft 89 is turned back with the backward rotation of gear 53, so that the locking-action will be released at each operation of the paper-returning' mechanism.

The details of the laterally-movable carriage will be found set forth fully in my said Patent No. 694,955, reference being made more esespecially to Fig. 2 of the patent. Referring to Fig. 7 of this application, 107 is the link receiving power from the reversing-lever 57. This link is connected to an elbow-lever 201, pivoted at 202 and carrying at the end of its long arm a pusher 109, adapted to engag'e the notches 200 in the bar 74 of the carriage, and thereby to shift the carriage laterally a column-space at each actuation, said bar acting as a spacing device. To prevent overthrow, I may employ the elbow-shaped latch 204, which is joined to the elbow-leverI 201 by a link 205 and enters notches 207, located between the notches 200. I may also employ a spring-pressed dolly-roll 208, entering the notches 207, to insure uniformity in the positioning of the carriage, the roll being carried on the end of the pivoted bar 209, which is pressed downward at all times by the spring 210. Further details of the carriage will be found in said patent.
