To all whom it may concerns Be it known that I, EUGENE A. FORD, or the city, county, and State of New York, invented a new and useful Improvement in Type-Writing Machines, which, is'fnil-yset forth in the following specification.

- The main object of my invention'is to con-' struct a simple and eflicient shifting mechanism, whereby e large number :of charactersmaybe printed from a few keys, without 10' shifting thoplatem'and whereby the typebars may be accurately guided to the prinb.

P int. Prior to myinvention it hasbeen-proposed r 5 to shift the type-bars (they having each two or more characters) instead of shifting the heavy carriage and platen as in the wellknown Remingtonmwhine. Tothis end-the key-leversand type-{mirehave been pivoted so upon a tilting frame, capable of being thrown at will into either of two positions, so as to. bring either'oneor the other of the characters (of the type-bar to the printing point.

- According to my invention, the type-levers and type-barsflare not carried .by a shifting frame, but the key-levers are'pivoted to a fixed support and each type-bar is'pivotedto the end of the key-leverfin such manner that, in addition to the ordinary stroke-for printing', imparted by said-lever, the type-bar can 'move independently thereof to bring any one of its characters into printing'position. With the type-bars so mounted, are combined shiftlng devices under the control of the operator;

3 5 forimparting to the type-bar, a movement in the direction of the alignment of the typed 'e.,'transversely to the printing stroke. This shifting device may, and does preferably perform alsothe. function of" a guide, controlling thehead or printing end 0! the type-bar to I the moment: of impact with the platen, In making a shift, therefore, it is not necessary to move a frame carrying sll'the key-levers andtype-bars. No key-levers move at all, sud only that type-bar need be materially displaced-which at the time being is in oper-- 'stion. here isi 'consequentl ya minimum weight ofthe shifting parts, giving; a lighter shift and much quicker. action. When a 56 heavy-frame is used, the spring that returns it, innit be proportionately strong, and the re- .advantages are durability, .cheapness and ing parts of. the machine, are attached rear-' sistance of thisspring must be overcome by the operator in making a shift. Additional simplicity of construction. 455' a My. invention further comprises an im-. proved quick-action feed mechanism for the carriage, as hereinafter specifically described, In order that my invention and the man-. ner in which thesame is carried into eflect 60' maybe fully understood, 1 will describe in detail a machine constructed in accordance therewith, referencebeing hadto theacooinpanying-drawings which form part' ofv this specification.

Figure 1, is 'a plan view, partly in section, of my improved type writing. machine. {Fig- 2, is a; vertical'longitudinal section. Fig. 3, is an end elevation of the type-bars, showing thetype-bar guide; and Fig.4,isanenlarged plan view of the carriage feeding'mec'hanism;

Similar letters of reference indicate correspending parts in all the'views'. To the base A, which supports all the workwardlylcurved pilla'trs' B, supporting rods a b, andnpon the said rods are loosely placed-theen'd piecesc of the frame of r the paper-car; ria'ge C. 1n the said frame is supported the paper supporting roller D.": The end piecesc are connected witha longitudinal bard, .carrying a double-rack bar e; Between ears 1; projecting rearwsrdly from thesupport g, are placed the p'awls h i. The said paiwls are held in place by a pin j, projecting through the earsfandthrough a. circular hole in the pewlt' and an oblonghole in the pawl h. The pawl h is provided with a right-angled arm 1:, furnished with a downwardly projecting!- shaped finger l, which engages 'theteeth of the rear surface of the rack-bar e. The pawl iis furnished with aV-shaped fing erm ,which engages the forward islide of the rack-bar'--e.-

In the pawl h,near its free end, is inserted an adj listing-screw n, which normally rests upon .95

the side of the pawl 11st its free end. The pawl h is held in engagement with'the teeth of the rear side of the rack-bar by a spiral spring 0, connected with the pawl and with a fixed support. The pawi-and-ratchetmecl1-.- iot- 8111511118 operated by arod. p in the manner presently tube described a To the fixed support in. front of the paper supporting roller Dis pivoteda-triangular rests upon the top of -the support 9, so that the guide is usedin this position while printing the frequently-recurring letters and cha ractcrs. The side walls of the triangular guide which converge to this narrow end, constitute guide-strips which control the head or-printing end of the type-bar, and direct the latter to'the slot orjopeninga In standards q r, attached to the base A, are pivoted levers s t, providcdat their rear ends with'studs n w for engaging and lifting the type-bar guide E. The stud w is made shorter than the stud '0, so that when the lever is tilted andthe stud is raised until the free end of the lever 15 strikes the angled upper end of the support 9, .the type-bar guide Ewill be raised sufii-v ciently-to bring'the central letter orcharacter on theend of thetype-bar into position for printing. In a similar manner the longer stud 0, carried by the lever s, -willraise the type-bar guideE whenthe said lever is' moved,

so as to bring the lower character on the end of the type-bar into position for printing.

- The forward ends of thefleverss t are con- 'nected with rodsa' b, which extend upwardly through the casing F of the machine, and are providedat their upper ends with fingerpieces 0' d, so that by pressing these keys the t 'pe-bar guide may be raised in the manner escribed.

In standards 6'', secured to the base A near the'front thereof, are pivoted the key-levers G, which are connected with type-barsH and with rods I, extending. through the casing F and provided at their upper ends with finger pieces f. As all of the type-bars, type-operati'ng levers, and parts connected therewith are alike in all'respects as to position in the,

niachin'eand the form of their free ends,- a

description of vone bar, and the mechanism connectediherewith will answer for the Whole. The lever G is formed of the longer arm 9', the shorter arm h,- aud the weighted arm 1",,

extending approximately at right angles in the main portion of the-lever opposite thev pivotal point," The shorter arm h is pivotally connected withthe internally-threaded sleeve j, into which is screwed the threaded lower end of the rod I. The free extremity of the longer arm g of the lever G ispivo't ally connected with the type-bar H, and the said type-barextends forward and projects into the forward end of the guide E. In front of theguid'e E is supported a slotted plateor comb .Lwhicn receives at each of its slots 'a type-bar, as shown in;I ig.-3. p The free endof'the type-bar I-I is'widened,

and in the present case carries type for pro-'- dneing three letters or characters. Either of the characters may be brought into position for printing by tilting the guide- E in the this movement of the guide andat the same time to preserve the alignment of the type, the end of the typebarv'is provided above and below with convex projections k; The rojdp ofthe carriage-feeding mechanism is pivoted to a. portion of the lever l, which turns on fixed pivots in the lower part of the machine-casing,and connected "at their upper ends by a rod-m. The said rod lies in of the typebar, so that as the type-bar is 7 moved forward, the impact of 'the projection which pushes the. pawl 11 forward, so as to bring the projection 'm into engagement with the teeth on the front side of the ratchet-bar e, at the same time,- through the medium of out of engagement with. the ratchet teeth. on the back side of the bar 6, thereby releasing the bar from the pawl h and causing it to be .held by the pawl 11. At the same. time the spring 0 draws the pawl h forward ready for re-eugagemeutwith the ratchet-bar'at'ter its release, which occurs when the rod 19 moves forward, allowing the pawl 71 to slip out of engagement with the ratchet-bar.

the manner described is moved forward one To provide for spacing without printing, an angled lever 0', pivoted in a standard project.-

by a rod 10' with the levers t', and is pivotally connected at, the other end with the rod g, which extendsup vardly through the easing,thepressure of the finger upon the-finger-piece 'r tiltsthe lever 0', pushes forward the mile, and releasesth'e feeding mechanism inthe'manner already described. A'n inking-ribbon of the usual description will ,be interposed between the type-bar E and they paper supported by the roller D.
