TYPE WRIIING MACHINE.

Specification of Letters Patent.

Patented Mar, 17, 1914.

implication filed December 2, 1309. Serial No. 530,919.

To aZZ u 7107/), it iv lay; cons-cm Be it known that l, rammes Dlmiccsnr BUsz, a subject of the Czar of ussia, residcity of rd snow,

or in new and ll Improve- TlypeWritinQ Machines, of which.

.fication.

This invention relates to types writers, ad l3 blocks, Wll may is reversed to bring into use other faces h lug diill'erent types; the object being to secure the changeable types firmly on the type liars, that they w ll maintain their proper inement and 'Wlll make clear imprints on the paper, and to produce a type-bur of this kind which shall be practicable, inexpensive and readily applicable tennis-ting machines.

in carrying out the ini vntion, I provide type blocks haviu "1W or type laces or sides, as E: an alphabetn cal characters, which. block; remova d bars I also provide ucui blocks lined on t c h In the accompanying dra and 2 are pelspcct c views or a I shoui two opposite sides healing letters from the Engl. sh and Russian alphabets, respectively. Fig. 3 is side view showing the type block applied to the type bar and ments in the following is a sp held fixedly thereon by the detent. l i is a similar view showing the decentv parlines showing the inverted. I shows the bar with the block remored tl'iereltrorn.

Upon a type bar A 1 l, havin a .uun'ibcr or fECl a type block cs, one of which 2,

lance; nis lug two he ca. When it is to .4 ange that it will write in Russian, instead of in English, example, the type blocks are taken oil from the type bars, reversed, and replaced on the type bars to bring the Russian types into use. This is accomplished by v l. duplex.

t g for type more particular I to type e the machine so type bars, the type blocks being capable of slipping on and oil the fingers, but not rototable thereon. 51a, have in- Owing to the rapidity with which the type bars are operated, and to the force with which the type strikes the platen, it is necessary that the type blocks be Well secured upon the bars to prevent them from accidentally flying oil or becoming displaced. Accordingly each type block is held firmly against a shoulder 6 by a detent or latch 7, which may be pivoted to the type bar at 7 and hooked to take over the outer end of the type block; a tooth 8 being preferably formed on the latch to be crowded over the outer end of the-type block, thereby placin the latch permanently under tension; sai la ch having a resilient construction to permit to be forced upon the type block. The

the stop 6 after which the resilient latch 7 isswung to engage the type block, its tooth 8 being forced over the outer end of the type block until it enters the recess or notch 9. To remove the type block, the latch is released and the block slipped off for reversal, cleaning or substitution, as desired.

The type is fixed very firmly upon the finger or tenon 5 of the type-bar, so that there is no possible shake or yielding of the type relatively to the bar itself, thus insuring that the type shall make good impressions upon the paper. The constant firm pressure of the block against the shoulder 6, effected by the tension of catch 7, is also conducive to this result. Moreover, the provision of the shoulder 6 is of value in alining the types,

, since the block must always come to the same 9 position on the bar, Whichever face thereof bears English type and mother, 3 a Rus- 2 pe block havis put into use; and the entire system of types can be readily alined with one another, depcnding upon shoulders 6 for finally positioning the blocks. The type bar A is usually formed of sheet metal, so that the finger or lemon may be readily formed thereon and have sufficient depth or breadth to give the tightly fitting block the requisite firm hold upon the bar. The latch 7 is providing the "type blocks with sockets 4 in placed under the block or in line Wl'fh the which fit; fingers 5 on the tree ends of the body of the bar itself or in ther words. is

i i 1 l i v mounted toswing in the same plane'in which the type liar swings. This compact arrangement, since the latch does not take up any room the side of the type-block, andhence the types may lie in their usual close arrangement in the type basl(et.-"

Having thus described. my invention, I

claim: 1. In. 'typewriting machine, the COIIlbh nation with a duplex reversible type head. ha ving surl'accs, a type bar having (veep-- crating surfaces su'o. untially parallel to Q each other sliding o'n-said first surfaces,nnd type faces on said head posit vely positioned and supported. by engagement of said surfaces.
