To 41/ whom it may concern: Be it known that NEY, a citizen of th and State of New Jersey, have tain new and useful Writing Machines, of which specification.

his invention relates to type-writing mnchines, particularly those of the front-strike class,- and its object is to improve the key touch and to sirnplif actions.

My invention consists in certain feature of construction and combinutimis of devices, which will be l'zercinafter fully set forth, and particularly pointed out in claims.

In the dram'ngs forming put? of llll specification, Figure 1 is a central longitudinul vertical section f n frontt the Writing-nuithe following n chine made in accordance the parts of the illustrated in not-null position. Fig. 2 shows the positions nssutncd by the parts at the time that the type impression is made Fig. 3 is a cross-section of the machine, taken at about the line .r J3 of i 'ig. 17 fig. 4 is n diugrarn illustrating the convergence of thc'rear portions ol' the key-levers.

The framing of the n'ntchine may comprise a base i, corner-posts 3, and a to plate .5. A carriage having. platen '1. nuty travel o vt-r the top plate. Types 5 are mounted upon the ends of rearvvardly-strilting type-bars 6, which are pivoted upon a curved rod 7 and Work in radial slots is, cut in a segment 9, in which said curved rod is fixed. The segment may be mounted by cars 10 upon a pair of fixed vertical guide-posts ll, whereby the segment may be shifted vcrticnllv. The type-burs at their hirivitrd upon it purl l2, ends of rods 13, secured upon segment.

At their upper ends the std:- lcvers are connected by l orwnrdlyu-xtending links 20 directly to the ty )c-lusrs.

A system of T-slmped lug-levers is pro-- vidcd comprising arms 2!, which extend lor- Vfitl'tlly beneath the typc-imrmz'md carrying keys 22, upWnrdly-cxtending arms 23, which are pivoted at 24 directly to the pt'hiliiii arms 1:) ol' the upstanding sublevers. nod downwardly and forwardly inclined arms 5. which are preferably longer than the arms .0 and have elongated convexly-curved trends :6, whereby "the arms are adapted to huvc a rocker motion upon a downwardly and forivurdly inclined and concave-faced bar, fulr,-rurn-plnte, or support 37, which is arranged on edge and supported at its ends upon the side walls of the base. Upon said bar is provided a guidewotnb 28 for the arms 25. 'l'hc rear chi ol' the key-lever is wholly supported by the pendent arm of the sublever, so as to prevent the elongated tread from becoming displaced vertically or longitudinally When a key is deproduccd upon the pressed, a tendency is part of the entire key-lever to vibrate about signs denote like presses as a fulcrum for thelever.
