TABULATING DEVICE FOR To It whom it may concern:

Be it known that I, CARL JULIUS MOHNS, of Chemnitz, Germany, have invented certain-now and useful Improvements in and Relating to' Tabulating Devices for T e- 'Writing Machines, of which the following is aspecification.

Myinventiorl relates to tabulating mechanism for typc-writing machines.

The object of the present invention is a device for moving the stop-bar in the tabulatinglmechanism of type-writing machines.

- to arrest the performing overcome said disadvantages.

shaped 2. This bar is also shaped for a short '(llS-ff In t e tabulating mechanisms whichwere used heretofore the movement of the stop-bar is effected by means of a lever capable of two different motions, so as to turn, on the one hand, the stop-bar around its longitudinal axis in order to release or paper-carriage, and to shift, on the other hand, said -stop-bar in the direction of its longitudinal axisin order to adjust the apparatus according to .a scale. Devices of this kind require comparatively much space, the lever being turned on its fulcrum in two different directions. Therefore it is diflicult to fit u said devicein the machine and its manipu ation requires comparatively much time and Work.

The purpose of the present invention is to This purpose is accomplished in such a manner that well-known lever for moving the stop-bar is replaced by a shaft which when shifted in its direction of length causes the stop-bar to be turned around by lever action, and which when slightly rotated around its longitudinal axis causes the stop -bar to be shifted by means of toothed gear.

The drawings represent a form of'execution of this invention. p

"In said drawings, Figure 1 is a longitudinal section. Fig. 2 is a longitudinal section along CD of 4. 'Fi 3 is a rear view. Fig. 4 is a view from above with the paper-carria e removed.

and sliding motion (See Fig.

e. parts are .6 5 7 ve stop-bar by means of lever 1',

r In the middle of stop-bar d is provided a:

tappet vu, (see Figs. .2 and 3,) which when bar d rotates turns a lever cover and de presses thus an ordinary movable escapement-tooth w of the carriage-escapement look, so that the carriage is released in that direction in which pulling strain isexerted by the spring of the usual carriage-moving mechanism. Lever 'v: operates a further lever as, one end of which'is guided against a brake-block y, the latter being thus forced against the brake-rod z with any desired degree of pressure. (See Fig. 4.)

The a ner: In ex g of the indicating device is adjusted so as to point to digits of scale p by means of turning button is. For regular written work the paper-carriage a is pushed until that place where a space has to be inserted reaches the spot where the ty es strike, and for tabular work it is pus e'd until the right column-line reaches said spot, and on stop-bar (1 stops e are secured, one after another, so that the stops in the notch on the right are placed in close proximity to the carriage-stop b. The then brought to the ed e of the sheet. If button is now pushed, ever 1' turns tappet s and at the same time also stop-bar d, provided with the adjustable stops 2. The latter are placedin the dotted position shown in Fig. 1, and the movable es'capement-lock paratus works in the following mantooth having been depressed through lever o paper-carriage is) by the turned stop-bar (1 said stops'check were just in motion return again into their posltlon of rest. In this manner spaces are produced fora regular written matter. In

' order to obtain wider spaces, the button is I of four ciphers, the button should'at first be turned until the index points on the scale to thousand. The stop-bar, with the stops, is thus moved by the width of three characters in a direction being opposed to that in which the carriage runs. If the button is now pushed, the free motion of the carriage is checked sooner, the difference amounting to the width of three ordinary characterspaces, and the operator is thus enabled to write a number consisting of four ciphers correctly under the preceding digit.

When the carriage-stop strikes against the stops of the stop-bar, a certain shock is ex.- erted on the machine. reduced to a minimum by means of pushing the button more or less through and applying thus the brake with increased or diminishcd force.

The aforesaid facts show that if the button is pushed but once the carriage runs from one column to the next one. If certain columns have to remain free, the button should be pushed as many times as there are columns which have to remain free that is to say, which contain no type-written characters.

What I claim is 1. In a tabulating mechanism for type- Writing machines the combination with the aper-carria e, stopssecured thereto, stopar mounte near said paper-carriage, said stop-bar having both a longitudinal and a rotary movement, and stops on said bar adapted to engage the stops on said papercarriage, of a shaftand separate means carried thereby for imparting either a longitudinal or a rotary movement to said stop-bar, substantially as described.

'2. In a tabulating mechanism for typewriting machines the combination with the This shock maybe.

paper-carriage, stops secured thereto, a stop bar mounted near said paper-carria e, said stop-bar 'having both a longitudina and a rotary movement, and stops on said bar adapted to engage the stops on said papercarriage, of a shaft, means thereon for imarting a longitudinal movement to the stopliar, a lever operated by said shaft, and means carried by said lever for imparting a rotary movement to said stop-bar, substantially as described.

3. In a tabulating mechanism for typewriting machines the combination with the paper-carriage, stops secured thereto, a stopbar mounted near said paper-caniage, said stop-bar having both a longitudinal and a rotary movement and stops on said bar adapted to engage the stops on said papercarriage, of a shaft, a lever operated thereby and adapted to im art a rotary movement to said stop-bar an a pinion on sa d shaft adapted to impart a longitudinal 11") ement to said stop-bar, substantially as described.

4. In a tabulating mechanism for typewriting machines the combination of the paper-carriage, stops carried thereby, a stopbar, adjustable stops carried thereby and a rack formed on said stop-bar, of a shaft having both a longitudinal and a rotary movement, a pinion carried by said shaft and engaging said rack, a collar on said shaft, a lever engaging said collar and means carried by said lever for rotating said stop-bar, substantially as described.

5. In a tabulating mechanism for typewriting nnachines the combination with pa per-carriage, the stops carried thereby, the stop-bar, the stops on said bar engaging the stops on said paper-carriage, the shaft hav ing both a rotary and a longitudinal movement and separate means carried thereby for giving said stop-bar a longitudinal and a rotary movement, of the carriage-escapement mechanism, a lever for releasing said escapement mechanism and means carried by said stop-bar for operating said lever, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
