SPECIFICATION forming part of Letters Patent No. 408,061, dated July 30, 1889.
- Application filed June 23, 1879. (Model.) Patented in England January 7, 1873, N0- 89- To aZZ whom it may concern:
Be it known that I, GEORGE V. N. YOST, of the city, county, and State of New York, have invented Improvements in TypeJVriting Machines, (for which I obtained English Patent No. 89 of 1878,) of which the following is a specification.
The nature of the invention is in the combination of a cast hollow base-frame which has an integral key-lever pivot-rib with the connecting-posts and cap-frame of a typewriting machine; inthe combination of' a swivel with the key-lever, connecting-rod, and
type-bar; in the combination of a connectingrod which has a bifurcated hinge end with the key-lever swivel and type-bar; in the combination of a bifurcated connecting-rod which has a bearing in each fork with a j ournal on each side of the outer end of a typebar, which is a lever of the first order; in the combination of a handle with and attached to the carriage and line-space apparatus; in the combination of two extra key-levers and connecting-rods with the platen transverse reciprocating apparatus in the combination ofa trip ratchet which has an elongated curved finger which surrounds the ratchetbar hinge-hub concentrically with the ratchet-bar trip-pin, and in the combination of a shield with and against the coiled spring and spring-wheel.
The invention is illustrated by the accompanying drawings and following description thereof.

bar or plate on and adapted to reciprocate forward and rearward along each end bar of the carriage J; K a lug extended down from the front end of each reciprocating plate K; K a lug extended up from the front end of each reciprocating plate K; L, a round rod attached to the under lugs K of the reciprocating plates K across under the carriage J parallel with the carriage-rail 1; L a bandpulley loose on each end of the combined connecting-bar and axle-rod L; M, a triangular plate pivoted to the upper lug K of each reciprocatin g plate K M a vibratory bar attached to the triangular plates M. of the reciprocating plates K across over the carriage .1 parallel with the carriage-raill; N, a bar or arm attached to the vibratory connecting-bar M and extended forward and adapted to Work in. a slot in the front bar of the carriage J; N a saddle extended down from the reciprocating arm N; O, a rocking bar across under the cap-frame 0 parallel with the carriage-rail I in bear ings attached to the front frame-posts 13; 0 an arm extended up from each end of the rocking bar 0 in a slot through the cap-frame C; 0 a bar extended to the upper end of each rocking bar vertical arm 0 across over the cap-frame C, under and adapted to work in the saddle N O ,.an arm extended horizontally from each end of the rocking bar 0, one forward and the other rearward; P, a key-lever on each side of and similar to each of the series or key-board of key-levers F; P, a connectingrod similar to each of the typebar-connecting rods l-I, attached to each side key-leverP and to the corresponding contiguous horizontal rocking-bar arm 0*; Q, a round platen parallel with the carriage-rail I across over the middle of the circle or disk of type-bars D in bearings attached to the reciprocatin g plates K; Q a ratchet-wheel on the end of the platen Q; R, an arm or lever hinged on the axle-rod L and extended rearward under the axle of the platen Q between the platen ratchet-wheel Q an d the end bar of .the carriage J; R a handle hinged on the axle-rod L, attached to or integrally a part of the hinged lever B, and extended forward and down in front of the cap-frame O; S,
a driving-ratchet pivoted to the hinged le-,
ver R and extended up behind and adapted to work in the platen ratchet-wheel Q S a holding-ratchet attached to the fore end of the contiguous reciprocating plate K and adapted to work in the platen ratchet-wheel Q T,a ratchet-bar parallel witlnbehind, and hinged on the carriage-rail 1; T an arm or handle attached to or integrally a part of the ratchet-bar T and extended forward and out under the hind end of the hinged lever B; T a circular enlargen'lent or hub of the ratchet-bar and arm T T by which they are hinged to the carriage-rail I; U, a trip-ratchet pivoted to the ratchet-bar arm T U a curved finger on the hind end of the tripratchet and elongated and adapted to work around the ratchet-bar hinge-hub T U a trip-pin parallel with the carriage-rail I, loose in a hole through the carriage-lug J and adapted to work against the tripratchet finger U The operation of the lever R and the ratchetbar T is as follows: \Vhen the front part of lever B is raised, it rotates the platen by means of the pawl S, and the end of the arm R strikes the trip-ratchet U, thereby depressing the arm T and lifting the ratchet-bar T clear of the pawls. The carriage then moved to the rightuntilthe trip-pin U strikes a fixed part of the machine, and is moved to the left, Fig. 3, which moves the trip-ratchet U from under the arm Rof thelevcr R This allows the ratchet-bar T to drop into engagement with the pawls while the arm R is still depressed.
V is an axle attached to a hanger extended down from the hind part of the cap-frame C over and parallel with the key-levers F; V, a plate or wheel, circular or scroll form, loose on the axle V; \W, a flange or rim parallel with the axle V and concentric with and attached to the periphery of the wheel V; X, a spring in scroll-coils attached to the axle V and wheel-rim \V; Y, a circular plate or shield loose on the axle V next to and against the coiled spring X on the side opposite to the wheelplate and attached to the wheel-rim V Z, a scale on which are vertical parallel marks correspondingin number and distance apart with the teeth of the ratchet-bar T, attached to the front edge of the cap-frame C; and Z an adj listing-slot in each end of the scale Z,
The cast hollow shell-like base-frame A is a convenient light cheap case for the key-levers F, solid and firm, and the pivot-rib A integral with the base-framefis a uniform firm journal for the key-lever bearings,whieh will always keep its relative place.
The series of key-levers F is wider than the disk of type-bars D, which makes the connection between certain key-levers and type-bars more or less laterally oblique. In some machines the key-board is much wider than the disk, and this lateral obliqueness in certain places consequently much greater, and this tends to pull certain type-bars out of place, and thereby destroy the alignment of the types; but the bifurcated connecting-rod H, screwed into the pivoted swivel G, with the fork-bearings over the journals of the typebar D, adjusts the connection to the least lateral strain and friction, and thereby remedies the defect.
The bifurcated or twofold type-body E allows two types to be in the same body and plane and transverse line, yet sufficiently apart foreach to work clearly and separately from the other, whereby one series of typebodies gives two series of types, of which one can be capital and the other small types. The round type-body shank E in the round typebar socket D allows each type-body and its types to be adjusted, and both types at once, as adjusting one adjusts the other-one to work in one line and the other in another and parallel lineand the platen Q, adapted to reciprocate forward or rearward, can be moved to one line for the capital types and to the other for small types, whereby both series can work in the same line on the platen and pa- The handle R by which to seize and draw the carriage J back to place after a line is written, is simple and convenient. At the same time when first seized it turns slightly on the axle-rod L and depresses the hind end of the ratchet-lever R, which depresses the ratchet-bar arm T and lifts the ratchet-bar T clear from the letter-space ratchets, and permits the carriage to be moved to the right or to the left. The lever R has also a rearwardly-extending arm 7 to arrest its further downward motion by coming in contact with the carriage-frame. The same motion of the handle R also pulls down the driving-ratchet S and turns the platen Q and paper a linespace distance; but, inasmuch as it is not essential in my machine that the handle shall be used for lifting the ratchetbarclear from the letter-spaee ratchet, as other means may be adopted and used for that purpose-as, for instance, extending the ratchet-bar arm T to the right and forming a thumb-piece thereon, as shownI desire to be understood as not limiting myself to the use of the handle R and its accompanying mechanism, or any accompanying mechanism, to the performance of all the functions before mentioned. It is clear that by omitting the connection or combination of the handle with the ratchet-bar arm 1 by cutting off the hind end of the ratchet-lever R, or otherwise, the handle R and its accompanying mechanism would be confined to the functions of moving the carriage to the right and left and rotating the platen by means of the driving-ratchet S, as before described. I do not wish either to be understood as confining myself to the rearwardly-extending arm R to arrest the downward motion of the lever by coming in contact with the carriage-frame. This may be entirely dispensed with, or other equivalent mechanism be substituted for the same purpose.
The depression of either alternate key-lever P will pull down a connecting-rod P and rock in g arm 0, and thereby work the rocking bars 0 O and the reciprocating apparatus N N K L M and move the platen Q and paper to the capital-type or small-type line.
To guide the reciprocating plates K, they have a longitudinal slot, through which passes a flat bar K, secured to the top of the carnot simultaneously, engage with verticallyprojecting lugs k on the ends of the fiat bar K. To release said pawls from engagement when the triangular plate M is rocked, said plate (at each end of the rod M carries two laterally-extendin g pins m to successively lift the pawls from engagement with the lugs 76.
The extension of the trip-ratchet finger U around the ratchet-bar hinge-hub T presents a solid surface to the trip-pin U at whatever position of the carriage, and prevents the trippin from catching and breaking on the end of the trip-finger, as is liable when the finger is not thus extended.
The coiled spring, when unprotected except by fastenings at the ends, is liable to bulge out laterally, and if it touches a substance which does not move with it friction and sluggish movement are caused; but the wheelplate WV protects and holds inplace the coiled spring X on one side, while the shield Y, attached to the wheel-rim lV does the same for the other side.
The drawings, besides many things old and common, show some things which are the invention of another. The combination of keylevers which have keys on one end,"pivots at the other, and connecting-rods between the pivots and keys, which pivots are rearward and connecting-rods forward of the vertical plane of the pivots of the letter-space ratchets, with the letter-space vibratory frame set between the key-lever pivots and connectingrods; the combination of a cam-wlheel with the driving-spring and carriage; the combination of a worm-wheel and spur-wheel with the spring-wheel; the combination of a guide with the inking-ribbon and ribbon-spool guide; the combination of a connecting vibratory frame and reciprocating regulating-frames with the ribbon-spools; the combination of a V-grooved traveling wheel and V-shaped rail with the carriage; the combination of bearing-wheels with the carriage and platen transverse reciprocating frame; the combination of alternate locks with the carriage and platen transverse reciprocating frame; the combination of alternate stops and latches with the carriage and platen transverse reciprocating frame; the combination of a vibratory connecting-frame and alternate lifts with the alternate stops and latches of the carriage and platen transverse reciprocating frame; the combination of an adjustable head with the band-shield; the combination of a head with the band-shield which has an adjusting-slot; the combination of a band-shield which has a holding-arm with the band-shield head and band-pulley, and the combination of a bandshield which has a bifurcated loose end with the carrying-ban d and reversed scale, form no part of this invention, but are the subject of an application for a patent to be filed simultaneously herewith by \Villiam K. 'Jenne.
But the devices which do constitute this invention, and what I claim, therefore, are as follows:
1. The combination of a single-tenon swivel with a flat-strap connection-holder F key IUO IIO
lever embraced by said strap, connecting-rod, and type-bar of a type-writing machine, substantially as and for the purpose set forth.
2. The combination of the type-bar of a type-Writing machine, its journal D secured thereto, with a connecting .rod IT, and its sprin g-fork I1 having bearings to receive and clasp said journal, substantially as and for the purpose described.
3. The combination, with the carriage and line-spacing apparatus of a type-writing ma chine, of a lever or handle extending in front of said machine and down toward the keyboard, substantially as and for the purposes described.
4. The combination of two extra lcey-lcvers and connecting-rods with the platen transverse reciprocating apparatus of a type-writing machine and a series of key-levers for operating the type-bars located between said extra key-levers, substantially as and for the purpose described.
5. The combination of a trip-ratchet which has an elongated curved finger Which surrounds the ratchet-bar hinge-hub with the ratchet-bar trip-pin of a type-writing ma chine, substantially as and for the purpose described.
6. The combination of the main spring of a type-writing machine, its shaft, and a shield loose on said shaft to prevent undue friction against said spring, as described.
