TYPE-WRITER.

fSt-uttgart, in the Kingdom'of Wiirtemberg,

Empire of Germany, have invented certain new and useful Improvements 1n TypelVriters, of which the following is a description, reference being had to the accompanying drawing and to the letters of reference marked thereon.

This invention has for its object improirements in those typewriters which are provided with a single series of keysand in which consequently separate shifting keys are provided. In such machines therefore hitherto-in order to write a ca ital letter, a separate key had always to Capital letters are however only usually employed at the commencement of a word, and it is therefore necessary to leave a space before them, that'is to say to also operate a spacing bar. Now various drawbacks are caused by this, in the first place such a double operation of the keys involves considerable loss of time as the spacing has first to be done, then the shifting completed, and then the letter key depressed, which not only involves a considerable increaseof labor but is a great drawback in the case of the extraordinarily rapid writing at present sought after. Further it very frequently happens that the capital letters are out of alinement if the key, as is often the case, be depressed before the shifting has been completdly effected. Thisdrawback is now avoided by the spacing bar being combined in a peculiar manner with the shifting key, so that by depressing the latter the spacing bar is simultaneously operated. The shifting lever is then automatically held down until a capital letter has been written, whereupon it is again released also automatically, so that without any other device small letters may be again written in the ordinary way.. Now if it be desired to write capital letters continuously the second shifting key usually provided in such machines may be utilized,

independently of the improved device, or the spacin bar also, as desired, so that the writing 0 a word entirely withcapital letters with or without spacing is in no way effected. The improved device is also chara front view of e depressed.

acterized by its being able to be subsequently applied with ease to all existing machines in this system, whereby the object of the inven; tion may be universally employed.

The invention is shown more particularly in the accompanyingdrawings, in which? Figure 1 IS a plan view of the keyboard with shifting keysand spacing bar; Fig. 2, Fig. 1'; and Fig. 3, an end View of same. L

The typewriter in accordance with this invention is proyidedwith a spacing bar a of the ordinary arrangement and method of working, and also with shifting keys 0 and c and-keys Z which work in the ordinary way.

Now in accordance with this invention, the spacing bar a is combined with the shifting key 0 by means of a bar 6 and in such a way that the spacing bar a may be depressed independently of the key a, while .vice' versa in depressing the shifting key 0 the spacing bar is carried with it. The shift-ing key 0 then encounters in the ordinary way the shifting lever e and is under the action of a spring all. Now if a capital letter is to be written and also a space made, it is only necessary to depress the key 0 which then carries with, it the bar a in the manner described. The shifting lever e is key Z be struck, it encounters in the ordinary way the bridge piece 71 which is provided with a projection is, which then encounters the free arm of the pawl f formed as an elbow lever and causes it to pivot, whereby the shifting lever e is released and the shifting action ceases. The shifting key 0 and spacing bar a are'in the meantime returned again to the no mal position automatically by the action 0 a spring (1.

As may be'seen more particularly in Fig.

2, if the shifting is to continue, the other shifting key 0 is operated in the ordinary way and also the spacing bar a, so that words may also be written consisting entirely of capital letters, and, if desired, with space between them( I declare that what I claim is In a typewriting machine, a spacing bar,
