To alt whom it rmty cancer-rt." v

Be it known that I, BUHNHAM 3. Brion- NEY, a citizen of the United States, and a resident of the city of Elisabeth, county of Union, and Stateof New Jersey, have invented certain new and useful improvements in lype- Writing Machines, of which the following is a specification.

This invention relates, rimarily, to typewriting machines in which radially-disposed type bars are arranged about a common prii'itingqniint and lnove'one at a time to the printing, position. These typebars, espe cially in lrimtsstrike machines, are often closely arranged, so that in rapid operation there is liability of clashing, due largely to the fact that the type-bars are apt to rebound from the basket or cushion upon returning to normal position, thus getting; into thepath of a subsequently-operated type bar.

The principal object of my invention, therefore, is to minimize the liability of the typebars to rebound in this manner.

In the drawings forming part of this specification, and in which like signs-denote like parts, Figure 1 is a'sectional elevation of a type-bar, typebasl ;et, and platen of an unturning the figure quarter-way around itwil be seen that it rep resents like parts in a front-strikamachine in which the,type-bars lie horizontally and below the plane of the printing-point. Fig. 2 is a plan of the type-basket or ring seen at .lllg. l, the type-bars being indicated in crosssection.

A radial series of type-bars 1, carrying typesZ, which. strike against a platen 3, is

supported by hangers 4 upon a ring, so inent, or plate 5 and operated by means of pu l-rods 6 or otherwise and usually provided with returning-springs The type bars normall re t in contact at their type ends with a flexibl ring or as mcnt, consisting of a casing 14 of some fiexi. ility and preferably tough and inelastic, filled with sand or other forcoabsorbing material 15, althou him some cases the casing need not be entire y filled by the material.

The device may be supported in any suitable way, preferably upon inturned fingers 9, formed at the lower edge of a thin still sheet metal ring or band 10, the latter being hung may possibly drive s upon rods 11, attached to the top plate 5 or otherwise supported. in front-strike Ina. chines the member 10 may be in the form of a segment and in some cases may be omitted.

The device being flexible yields more or at the impacts ol'' the type-bars, and owing to this yielding movement some of the adjacent and opposite type-bars are jarred,

thereby taking up much of the-force of the blow and minimizing the reaction of the parts, so that it does not tend to throw the type bar back with. force, the tendency of the same to rebound being lessened, While owing to the inelastic character of the filling the force of the original blow of the type-bar is still further absorbed, particularly because the filling is incased in'soit inelastic material, so that the bar u ion striking the basket lightly past its normal position, but will not rebound to the extent of causing it to clash with a subsequentlyoperated type-bar. This enables the operation oi the machine at high speed without den or from this source.

'1 e curved frame or ring 10 is substantial and protects the cushion from injury. It also prevents undue displacement of the cushion. Preferably a narrow space is left at 12 between the ring or segment 10 and the inner member, so as to allow slight-headers. of movement of the latter. Durin, such movementi there may be more or less .riotion between the cushion and the fingers or shelves 9 whereon it is so ported, thereby further tending to absorb tie force of the type bar ows.

lhe filled or partly filled casing 14 is head ble and inelastic, rendering it desirable for a type-basket, either with or without the still rmrror segment 10.

Variations may be resorted to within the scope of my invention, and portions of in r improvements may be used without other Having thus described my invention, *5. Cl9,iIt'-- 1. In a type-writing nation with a series r" therefor consisting o fined within a satin rial.

in a type-wri ns, a iy oe rest consisting of a whiny; as u raufili'l cent in therein.

3. in a type-writing machine, a curved typebar rest consisting of a casing of pliant materiel and a filling of granular material.

in a typewriting machine, the combincticn witl e series of type-bars of a pliant member iii rrnin a rest for the t e-bars and,

non resihentfil 111g, producing; a ad that is t e b absorbent cf the, energy of ow struck by the type bar, and non-resilient under said 0 ow.

7. In a type -Writer, a yielding inelastic cushion to support the ty e -bars in their normal position, consisting 0&1, sheath, and a filling made of finely-divided material.

8. A type-bar cushion comprising a yielding striking-surface and an inherently nonresilient shock-absorbing medium beneath the strikingsurface. Y r

9. A type-bar cushion comprising a yielding striking-surface and an inherently non- .resilient shock-absorbing medium beneath the striking-surface and movably supporting the same.

10. A type-bar cushion comprising e striking surface or facing of yielding material, said material being sufnciently yielding to prevent sudden arrest and consequent rebound or sprin in of the type-bars, and a non-resilient s cc absorbingbacking for said facing, said backing being sufficiently non-resihent to absorb the energy of the returning type-bars, and being also movable so that both the faciu and the backing may be displaced b the 1m acts of the t ce-bars; said cushion eing su ciently yiel ing and nonresilient to prevent injurious rebounding of the type-bars therefrom.

11. A type-bar cushion comprising a yielding facing of tough material, said facing being inelastic and pliant, and a yielding in elastic shock absorbing backing; said cushion bein sufficiently yielding, inelastic and shock a sorbing to prevent iniurious rebounding of the type-bars.

12. A type-bar cushioncomprising a facing of inelastic, pliant leather, and a yielding, inelastic shock-absorbing backing; said cushion being sufficiently'yielding, inelasticand shock absorbing to prevent injurious rebounding of the ty e-bars.
