DANIEL W. SHIEK, OF CHICAGO, ILLINOIS.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed March 1, 1905. Serial No. 247,847.

To all whom 'it may concern:

Be it known that I, DANIEL W. SHIEK, a citizen of the United States, residing at Chicago, county of Cook, and State oi Illinois, have invented certain new and useful Improvements in Tabulating Attachments for Computing-Machines and the Like, of which the iollowing is a description.

My invention relates to mechanism adapted to be attached to computing machines or similar devices whereby the characters printed by the same maybe conveniently arranged in lines, with the characters in the several lines arranged in rows or columns at substantially right angles to the general direction of the lines. i

The object o my invention is to produce a simple,

' convenient, and effective device of the kind described,

having a wide range of adjustment and one which may be quickly and positively manipulated to maintain the line or horizontal spacing to produce the desired columns, or vertical alinernent oi the groups of figures or characters.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described and more particularly pointed out in the claims.

In the y accompanying drawings wherein like or similar reference characters indicate like or corresponding parts, Figure l is an elevation of a portion of a computing machine equipped with my device, a portion of the platen roller being broken away to more clearly show my device. Fig. 2 is a view of the tabulating mechanism and rack bar in their cooperating position showing the tabulating attachment secured to the frame of the machine. Fig. 3 is a view of the mechanism shown in Fig. 2 as seen from above. Fig. 4 is a section-taken substantially on line 4 4 of Fig. 3. Fig. 5 is a section taken substantially on line 5 5 of Fig. 2. Fig. Gis a section taken substantially on line 6 6 of Fig. 1. Fig'. 7 is aview similar to.Fig. 2 but showriage and the rack bar secured to the frame of the machine. Fig. 8 is a section taken substantially on line 8 8 of Fig. 7. Fig. 9 shows a modified form of part of the mechanism shown in Fig. 4, and Figs. l0,4

11, 12, 13 and 14, illustrate various groupings of figures which may be secured with my improvement.

As shown in the. drawings, l, 1, Fig. 1 represents the carriage frames of the machine which support the platen roller 2. This platen roller may be of any construction suitable for the purpose and is provided with milled Wheels 3 3 for effecting the rotary movement of the same by hand. At the rear of the machine and secured to the carriage frame thereof is a rack-bar 4 of the usual construction in machines ol this kind. Secured to the fixed frame of the machine is my tabulating attachment. Obviously however, the position ing the tabulating attachment secured to the car` of these parts may be reversed if desired with the rackbar secured to the iixed frame and the tabulating attachment secured to the carriage frame of the machine as shown in Fig. 7.

My tabulating attachment consists ol an outer plate 5 provided with a Iinger piece 6, and coperating mechanism to be hereafter described. One side oi this plate is extended longitudinally of the rack-bar and is secured to the fixed frame as in Figs. 2 and 4 (or to the carriage frame ol the machine as in Fig. 7). This longitudinal extension 9 is provided with an upright 10. An inner plate l1 of the same general outline as the circular portion of the outer plate 5 is secured to the terminal key piece 11a of a revoluble spindle l2 which passes through a circular opening in the outer plate 5 and is rotated at will by means of milled Wheel 12. intervals upon its periphery, as at 13, for a purpose hereafter described. Pivotally secured to the inner plate 11 are a series of spacing wheels 14 of different diameters, and coinciding in number with said notches. In Fig. 4 I have shown the toothed Wheels mutilated upon one side only, while in Fig. 9 I have shown them provided with teeth at regular intervals around the circumference and delay surfaces between.' Either form will operate satisfactorily in the use of the attachment. f

Secured to the upright 10 at the points 15 and 16 are apair of bell crank levers 17 and 18. The short arms of the bell crank levers are united at 19 by a pin and slot connection or equivalent means.' Upon the free end of lever 18 is a pin or projection 20 which iits into the notches 13 upon the periphery of the inner plate 11 and determines the engagement of the corresponding spacing wheel with the rack. These bell crank levers 17 and 18 are provided with a spring 2l at the pivot point of the lever 18 to the upright 10, of suficient resiliency to maintain them in the position in which pin 20 is engaged with a notch, and the spring 22 coiled about the pivot of lever 17 and seated at one end in the frame bar 22, and at the other end against a pin from the heel end. 22b of the plate 5, acts upon the latter and the mechanism supported by it to carry it resiliently towards the rack so that said mechanism may be raised out oi engagement with the rack at any time to allow the spacing wheels to .be moved over the teeth of the rack bar when Vthe position of the tabulator is changed.

As above described my tabulating attachment is secured either to the stationary 'frame of the machine or to the carriage in such position that the mutilated portion or delay surface of the spacing wheel in use at any time is upon the teeth of the rack bar with the first tooth upon either side of said delay surface engaging the teeth oi the rack bar corresponding therewith, as shown in Fig. 4.

This inner plate 11 is notched at It will be observed that the wheels are of different sizes to be used in varying the spaces between the columns. These wheels may lor convenience be numbered. An opening 23 may be provided in the outer plate 5 past which opening the wheels revolve, a number upon the plate l1 showing through the opening and indicating the spacing wheel in use.

In Fig. 4 I have shown the tabulator set for use with the medium Wheel in position lor operation. The operation is as follows: A sheet of paper is first placed beneath the platen roller, and after determining the number of columns of figures to be printed, and the space desired between said columns, the operator adjusts the tabulator so that the delay surface of the proper Wheel 14 rests upon the rack 4, and moves the carriage to the desired position= i. a., a position in which the type will register with the desired position of the right-hand or the left-hand column of figures. The first number to be printed is now set up in the machine, and the operator, by means of the keys (not shown) causes that number to be printed upon the paper in the desired position.

The computing machine contains nine (more or less) type carriers arranged in a horizontal row; so that any ordinary number, -and therefore a whole column oi numbers, may be printed without moving the papercarriage longitudinally.' The platen roller of the carriage is of course rotated a certain distance, after the printing of each number, by certain mechanism (not shown) belonging to the computing machine, which mechanism hasno relation to any longitudinal move ment of the carriage.

When .the first column of figures is completed, the operator 'manually shifts the carriage to the right or the left (as the case may be) until the wheel 14 which engages the rack makes a revolution and its delay surface comes again into contact with the rack; and said wheel being spring-pressed against the rack, as hereinbefore described, the movement of the carriage meets a sudden addedlresistance, by which the operator is notified that the carriage is in proper position for the next column of figures.

In case that spacing-wheels such as are shown in Fig. 9 are employed, the'operation is the same, excepting that these wheels would stop five times during a revolution thereof.

To make the operation of this tabulating attachment more clear I'will follow the operation of printing three columns of figures, taking for example those show'n in Fig. 10. Supposing that the operator desires to print the left hand column lirst; after adjusting the tabulator for the purpose of engaging the proper 'spacing-wheel with the rack, the operator brings the platen-roller and carriage into position for printing the first number, 467,899. This being printed without any movement of the carriage (as already explained) the operator causes the platen-roller to turn, by operating independent mechanism (not shown). Then the next number, 987654, is printed, and the last number, in that column, 322339. The operator nov:r shifts the carriage to the right, and the carriage will be arrested by the action of the spring-pressed spacing-wheel. The operator turns the platen roller back to its initial position, and the first number (965432) of the second column is printed followed by the others, as shown. The shifting of the carriage lor the third column is identical with the shifting for the second column, as described.

lf it is desired to use an index number after a large number, the form shown in Fig. 9 is particularly adapted for such purpose. For instance, 1,374,240- 24, he will adjust his machine for vertical alinement at the units side of the column as before, set up the large number and print it, then by hund move the carriage une or two notches, (the click of the delay gear as it passes over the bar notifying him of the number of spaces or notches traversed) then set up the index number and depress the operating lever as before.

Whenever it is desired to increase or diminish the space between different groupings or columns to`be added, the operator-changes the wheel in engagement with the teeth of the rack bar by pressing with the thumb and finger, lever 17 towards finger piece 6, which operation will, through pin and slot connection 19, elevate the pin or projection 20 out of the notch 13, and then the operator, by turning spindle 12, brings into position the next gear desired for use, either the larger or smaller one, when lever 17 is released, and the pin 20 is allowed to drop into the notch directly above the wheel then in engagement with the rack bar, and the machine is now ready to adjust the vertical alinement of another column of figures.

I do not desire to limit myself to the Vexact construction of the tabulating attachment described nor to the employment of the form of toothed wheels shown to the exclusion of other adjustable spacing and retaining mechanism for producing the same effect, but reserve the right to make such changes as fairly come within the scope of my invention. I
