Li'H E. EDVJRDSND FRAITK RUSSELL, OF DALLAS, TEXAS, ASSIGNCRS T0 GRAPHXC WRITING-PIAHNES.
2, all whom/i1? m (13,/ colzccrn lle it known that we, ALRAH B. `i loxvliime :md liimx it l. lfifssicmi, citizens of the 'United iitetes, residing at Dallas, in the county Bailes :and State of Texas, have invented certain. ii" und useful Improvements @riti C ziel'iiiies, of wliiell the. following specification.
Uur invention relates to steiiograpliio l oewrii iig machines, :incl relates more tculo ly a striking ineelioi'iism igor` suoli maeliiries.
object of our invention is to provide i stirring mechanism for stenograpliio type-- writing machines which mechanism will be rendered almost iioiseless in operation by niouotii'ig .the type-carrying extremities' the striking members or type bars Closely' acljzieent to the platem' so that the stroke .et the type 'bers will loe the ieest possible.
fiiiiotlier object ie to provide e simple means for engaging eiieli type bei' with o pivoteel universal ber, the lrite being otecl upon by spring which will. cause :my -tvpe bei: to liereturnecl to its normal position lin been displaced tliroug'li the of a key.H U A. iiurtlier object is to provide e. striking mechanism .for ai stenograplie typewriti iiizieliine, the parts of which uieelienisiii v. lieve zur r adopted to oe comparatively :mijl labor.
'Vitli these miel 'various other objects iii vier/f', our invention has relation to Certain il. eine siiiiplioity miei will be assembled or teiten apartwith small expenditure of time nove?. features of the Construction miel operation? example of ivliioli is described in the following speeiliczitioii7 noci illust"fitefi` 'in the accompanying flrawiargs wherein.:
l is a top "or plan View of the meelimiiszzi Comprising the herein described invention, chine as said.
suoli parts of the typevi'ritiig mo.- nre not directly correlated with invention, being oiuittefl from this F50 2 is z. vertical, seotioiizil View .v tion.. showing et 'portion ot the 'ine of the typewriter, the plane section seing 'tellen parallel to tl'ie gicle walls of the Specilca'tion of Letters Patent.
the numeral 'l denotes a levers pivotolly Walls 2 of the being slightly which s -oports the machine. extremities; ot the levers l, meiiiitecl upon trod 3 ing between the rear mounted. between the side machine casing, said levers The are pivote/ily transversely eXtencL portions of the side plurality of key spaced. from the surf-tice weils i?, slots; sl being provided in tlieupper been subjected to a downward, angular dieplacement. The middle portion of each spring 5 rests transversely upon the rod 3 adjacent to the correlated lever, and the fer1n Ward and. rearward, extremities of each spring are respectively hooked beneath the correlated .lever and beneath a roel 6 joomlto the rofl 3 and slightly spaced to the rear thereof. The forward. extremity of erich. lever Carries the usual key or linger button The rear portions of tlie liiejy levers l are parallel nml spaoecl im egual clistnuee apart. while the forward. efitreliiities of Seial levers are diverged from each other iii ien eli:ape. A. short splice above ...lie middle portions of the key .levers l., e. rod S is transversely extended between 1'. e side Walls of the machine, ond upon this roel :ire pivotally mounted the lower extremiti of a plurality of substantially upright type bars i), @zich having :ui integral, rearwardlvv extending; arm l0 provided' to its lower portion, the free emi of which arm is connecte@ "with, the middle portion of the correlated key lever by a swinging iinli il.
lo. order to facilitate the assembling :incl ding the iiiaol'iine, the pivotal mount type bers accomplished by proeoe bar its lower eiicl with :L slot said. rml. A. Wire spring i3 is ti eaeli type. bar to hold; the
thus established between each type bar andv the universal bar is such that a rearward angular displacement of any type bar will be communicated by the hook 17 of said type bar to the universal bar, but this rearward displacement will not be communicated by the universal bar to any of the After any type bar has other type bars. completed its stroke, it Will be automatically returned to its normal position due to the rearward movement to which the universal bar is subjected by the spring 16. The type, one of which is provided at the upper eX- tremity of each bar 9, is indicated bythe numeral 18. The inking ribbon 19, platen 20, paper 21v and paper roll 22 may not properly be-considered features of the striking mechanism, but they are shown in the drawings to more readily explain the construction and operation of the invention. It is to be observed that the type bars 9 are parallel arid equidistant, the space between y said bars being considerably less than that has been struck.
whichA separates the parallel portions of the key levers. The leverage provided by the key levers 1 is; such that a very light touch is sufficient to operate the striking mechanismlabove described.
The' .invention is presentedas including all such modications-and changes as properly come within theV scope of the following claims.
j What we claim is:
1. In a stenographic type-Writing machine, the combination with a plurality of key levers, of a horizontal rod upon which the rear extremities of* said levers are pivoted, a rod parallel to( the first mentioned rod, transversely extending above theumid- ',dle portions of the key levers, a plurality of type-bars equal in number to the key-levers, pivotedupon the last mentioned rod, an arm projecting rearwardly from each type-bar, a universal bar pivoted upon the last mentioned rod, a hook` projecting forwardly from each type-bar and engaging the universal bar, producing a displacement of the latter bar when any key is struck,.and means for automatically returning .the universal bar to its normal position, after any key 2. In a striking mechanism for stenographic type-writing machines, the combinationy with' a plurality of key'levers pivoted at their rear ends, of a plurality of type-bars, a hook projecting from each typebar, a transverse universal bar, pivoted uprights supporting the universal bar at their upper ends, said hooks normally engaging the universal bar, a coiled spring connected to the universal bar and to a stationary member, projections on the type-bars, and linksl attached to the key levers and the projections of the type-bars.
3. In na striking mechanism for stenographic type-Writing machines, the combination with a plurality of key'levers pivoted at their rear ends, of a plurality of typebars, a hook projecting from each type-bar,
a transverse universal 'bar in the-path of the hooks, pivoted uprights supporting, the universal bar at their upper ends, the hooks normally engaging the Iuniversal bar, a coiled s ri connected to the universal bar and` P Hg to a stationary member, projections. on the type-bars, links attached to the key levers and the projections of the type-bars, and spring members engaging the type-bars and holding the same in normal position.
il, In a striking mechanism for stenographie type-writing machines, the combination with a plurality of key levers pivoted at their rear ends, of a plurality of type 'bars having pivot points closely associated and provided with projections, each projection except one at the center of the machine being directed laterally towar a correlated key lever, a connection from each type-bar projection to its respective key lever, and a swinging universal bar associated with the closely associated portions of the type-bars.
5.' In a striking mechanism for stenographic type-writingr machines, `the combination with a plurality of key levers pivoted 'at their rear ends, a plurality of type-bars l'faving pivot points closely associated and provided with projections, each projection exceptone at the center of the machine being directed laterally toward a correlated keylever,a1`connection from each type-bar projection to its respective key lever, a lswinging universal bar mounted adjacent the type-bars, andhook extensions on the closely associated portions of the type-bars engaging the universal bar.
In testimony whereof we have signed -our namesto this specification in the presence of two subscribing witnesses.
