.To all'w hom it may concern.-

Be it known that I, GEORGE-M. KITZMIL} LER, a citizen of the United States, and a resident of Norfolk, in the State of Virginia, have invented certain new and useful Improve ments in Type-Writing Machines, of which the following is a specification, reference be- I a vertical 'sectionalelevation 'taken-longitudinally and about centrally of a front-strike.

' mize the depression or di ing had to the accompanying drawings, forming a part hereoii v This invention mechanism and cooperative parts of writingmachines.

. One of the objects of the invention is to improve the touch of the keys and increase the speed of operation, and another is toministill-maintain a quick the printing device.

To these'and other ends my invention consists in certain combinations of devices, arrangement of. arts, and featuresof construction, all as wi 1 be hereinafter fully set forth,

an powerful blow of and'particularly described in the concluding In the accompanying drawings, Figure 1 is writing-machine embodying my im rovement and showing the parts in norma position. Fig. 2 is a skeleton view similar to Fig. 1, but showing the parts inprinting position.

Fig. 3 isa front elev'ation showingthe typebar and link-hanger supporting rings and type-bar guide. Fig. 4 is a plan View of same. Fig. 5 is a sectional fragmentary View of the type bar and link hanger'or actuator support- I ing rings. Fig. 6 isan'edge view of the typenumerals o bar-retaining plate. Fig.7 is a plan'view of the same. Fig. 8' is a rear sectional elevation showing the manner of'connectin the operating or sublevers to the slotte swinging link-hanger.

Similar reference. The framework of the machine comprisesa base 1, corner-posts 2, atop-plate 3, over which is suitably mounted a traveling platen 4.

' The impressions upon the aper are made by types 5, carried upon the orward ends of rearwardly striking type-bars 6, Whose rear ends are pivotally mounted upon a curved fulcrum-rod 7, fined im-a sermcircular sup: port 8, which is provided with .radial'islotst, and a peripheral slot 10, the radial slets l) torelates to key-controlling of the keys and parts are designated by similar .ment with the type-bars 6. a actuators 24 are. provided with a two-way;

receive the hubs of the type bars and the slot 5 5 10 the fulcrum-rod. The type-bars 6 at their point of fulcrum are provided with an 0 en slot 11. The metal above the fulcrums ot, asshown in Figs. 1 and 2, from the center of the fulcrum-rod, is formed to describe an are of a proximately ninety degrees. At the 'endof the slot 11 and atright angles thereto there is provided a lug 12. Conforming to the curvature of the semicircular support 8 is attached a retaining-plate 13, 6

provided with teeth 14, Figs. 6 and 7. f In normal position, as shown in Figs. 1 and 2, the teeth'M permit the arc of the type-bar 6 to freely move around the fulcrum-rod 7 while the lug 12 prevents the type-bar 6 from 7;

dropping from the fulcrum-rod 7 when in printing position or just returning therefrom.

' The slots 16, Fig. 7, affordmeansfor moving the retaining-plate 13 in order to remove the type-bars 6, in which event the screws 17 are loosened and the retaininglate 13' moved so the spaces 15, Fig. 7, wi come, opposite the arc of the type-bars 6, Figs. land 2, when one or'more of the said type-bars -may-be easily removed without disturbing the ful- 8o cram-rod 7.'

-The link hangers or actuators 24 are pivotally mounted in the same plane as or in alinement with the t e-bars upon acurved fulcrum-rod 22, fixe in a semicircular sup port or ring, 19, which is provided with radial slots 20 to receive the hubs of the hangers'or actuators 24 and the slot 21 toreceive the fulcrum-rod22. The semicircular support or ring. 8, hereinbefore referred to, and

the semicircular support. or ring 19 are at' right angles to and project or extend out on either side of the web 18 and are integral therewith. The radial slots ofthe supportin %ings 8 and 19 are in line with each other. 9 5

hile I haveshown the supporting-rhigs 8 and 19 and the web 18 as integral parts, I

.amnot confined to that construction, as I witheach other, the hangers} and. links being to 5 to the rear of and in-the same plane or in aline The hangers or or angular slot-that is, the fulcrum-slot 2-5 and the operating-slot 26 are at different'angles to each other,,but have a common open ing. The slot 25' opening, as it does, into slot 26 affords means for quickly and easily-removing the said hangers or actuators 24 without disturbing the fulcrum-rod 2'2 and also tends to prevent. said hangers frornlii t- -ing while in operation. The slot 26. is for the movement of the hangers 24 by means 10f the pin 27 in the intermediateorsublever 28,

of which there is a series arranged side it side and which vibrate .or oscillate on a in crum-rod. 29' a slotted transversely-disposed support 30, which may be'suitably secured to the base 1 of the machine. v

The purpose of forming the slot 26 at an angle, as shown in Figs. 1 and 2, is that at the commencement and near the end of the stroke the maximum leverage is obtained and decreased as the pin 27 of the sublever 2S creeps in the slot 26.

The intermediate or sublevers 28-areupwardly directed and of 'variouslengths, according to their position in the series, each one from the center being bent more or less in one direction (Snthe other, according to its position, to bring its upper end into proper.

relation with 1 respect. to the corresponding link hanger or actuator 241 and to conform to the radius of the'semicircle-in which the typabars 6 and link hangers or actuators '24 ,are fulcrumed. I i

The levers 28 are provided with arms 31 at right angles thereto, at the'end of which are curved projections provided-with in-,

wardly-open slots 32 of greater or less angularity, according to the length of'the le- 'vers 28and their position in the series, those nearer the center being provided with slots of a greater degree of angularity than thosep when. the hanger or actuator 24 is moved forward travels rearward and forces the vibrating bar 42, which is seated in the slot 43, rearward. Motion is communicated through the rod 55, which is secured-to the'vibrating bar .42, to the detent-shaft 46, through the slot 44 and the pin 45. The vibrating bar .42 is curved to suit the curve of the semicircular support 19 and the slot 43. 1

' Mounted on the web 18 are two bars 47,

each extending to, or near the center, of the web and provided with an u set or arm 57 to form a guide for the typeare 6 whenvin hub 63 near thefulcrum-slot o tosecure by Letters Patent, is-

ceases fprinting position. Each "ofthese "barsare.

provided withprojections' .48 and-49.; 1ii t4, or securing them to the-semicircularsup-j ports 8 and 19- and the web 18 byfthe screws 50. The projections .49 extend over the semicircular support 19 and arearranged tomovably mounted the rod 51, de

from which are links 53, which are t P ns t pivotal y connected to a lug 54onthe rod 55, which'rod is'attached to the vibrating bar 42 at one end and the detent-shaft '46'a't, the other end, the'eonnection'with ,the. shaftv 46 being by a slot 44 andfa pin. 45. I 4

In the operation-ohmy-invention-the parts coact in'the followin manner; :A; depression of the finger-tip 58 0 theleven33 causes vthe pin 35 inthearm. 34' to slide o'r creepfin the slot. 32 ofv the sublever 28,- which vibrates or oscillates on its fulcrum-rod 29. Thev upper end of the said lever 28,v moving forward,

forces the hanger or actuator-24 through the pin27 in the slot.26. to likewise move -for-- ward, causing the type-bar 6, throughthe link23, which is pivotally connected itosthe crank of the t e-bar and to the hangerpto oscillate aroun the fulcrum-trod 7' until the type-head reaches the printing-point.
