To all whom yit may concern:

Be it known that l. Enum* G. Larra, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York. have invented a new and useful Im )rovement in Type-Writing Machines, of which the following is a specification.

This invention relates to improvements in front strike or visible writing typewriting machines in which the type-bars are mounted on a supporting segment which is adapted to be shifted for placing one or another of the sets of type on the type-bars in printing relation to the platen.

One object of the invention is to provide a typewritimlr machine of the Moyer make with a shiftable ty e-bar sefrmciit and adapt various features o the mac iine for coperatioii with such a shiftable segment, as hereinafter described and set forth in the claims.

(')ther objects of the invention are to provide a typewriting machine having a shiftable type-bar segment with efficient and practical mechanism for operating the carriage esca ment, and, preferably, the ribbon vibrating device also, by the direct action of the type-bars; also to arrange and connect the parts of the iiiachine in such a way that they can be assembled and dis1 mounted with ease and rapidity; also to connect the ribbon vibrator lever directly to the. universal bar without the use of intermediate or separate loose connections, and to do this in a way that permits of different motions of the vibrator for moving either one of a plurality of di'eieiit portion-5s or fields of the ribbon to and from position for printing, and permits the vibrator to he thrown out of action; and `also to` improve visiblewriting typewriting machines in the other respects hereinafter described and set forth in the claims.

In the accompanying drawings, consistw ing of five sheets: Figure 1 is a longitudinal sectional elevation of a typewriting machine embodying the invention. Fig.'2 is a fragmentar)1 similarsectional elevation showing the position of the parts when the segment is shifted. Fig. 3 is a longitudinal sectional elevation, on a reduced scale, cf the top plate of the machine. Fi 4 is anrenlarged sectional elevation of tie operating means for the ribbon Yibrator. Fig. 5 is a plan view, partly in section, of the machine, the carn riage being removed and the carriage guide being partly broken away to disclose the nnderlying parts. Fig. 6 is a rear elevation thereof partly broken away and partly 'in section, in line 6 6, Fig. 1. Figs. 7 and S are respectively a fragmentary longitudinal sectional elevation and a rear elevation, partly in section, of a modified construction.

Like reference characters refer to like parts in the several filaires. l

The construction illustrated in Figs. 143 will be first described.

A represents the main frame of the inaehine; B the top plate thereof; C the platen *carriage which supports the platen c; I) the carriage escapeinent; E one of the ty `e-bars which are pivoted in iin arc below tlie carringe so that the type-bars can swing upwardly and rearwardly to make the im ressions at the front side of the platen: the key levers and f oneof the auxiliary levers 0 rated thereby for actuating the t vpcbars.

ese parts. except as hereinafter explained, are, constructed, arranged and operated as in the Mover typewriter and are illustrated to show their relation and coaction with vthe other parts of the machine.

The top plate B is a single casting of substantially uniform thickness throughout which is removably secured on the iiiaiii frame A, for instance, by screws l, Fig. 5. at the four corners of the top plate. The front and rear portions of the top plate are in different hori'fgoiital planes and the cciiiiectiiigr middle part is curved as shown best in Fig.

The middie part has two raised side portions if b. Figs. 3 and forming forwardly inclined (lat .seats for a carriage track or guide casting B. 'llie cciitral part of the top plate is removed oi-,pi'oviiied with aii opening L having large front and rear portions and a narrow connecting portion to permit the t); ie-bars to suing to the platen and to admit t ie univer. :il liar. ril iwii vibrator and other parts when as eioliling them in the machine. The horizontal froiit portion of the top plate is preferably provided at o iposite sides with deprc sions Il having' iiicii'ned bottoms to enable the ribbon spools, one of which is shown :it i, Fig. l, to be a rranged in au inclined bositioii with their front lower cfliges below the surface of tho lirontl part of the top plate so :is to deliver the ribbon iu Eine with the ribbon \ibr:ito:v

The. carriage tir-.rk casting li supper# the guide or track on which the carriage travels transvtrsely of the machine. The carriage tracll; or guide shown is of the hall bearing type used in the Moyer ma chine, hut track or guide of any` other suitable sor* could he used. The track cast ing B is rigidly secured' on the inclined seats bof the to i plate, for instance. by four screws Z7, two o` whichY are shown in Fig. 5. By the use of a ssei'izirate track casting secured on the top plate the machine can be readily supplied with track castings of dif-- ferent lengths suitable for different length carriages.

The carriage escapement D is mounted on a suitable bearing or portion l on, the rear central ,portion of the track casting B', the shaft fi of the escapement Wheel being, as usual, provided at its front end with a gear pinion d2 which meshes with a rack har (Z3 on the carriage.

(l represents the segment or support :nar the type-hars- '.Fhe segment preterahly consists of '.14 curved or segmental casting having a slotted flange projecting forwardly from its upper edge 1n which hangers y for the typebars are secured by clamping plate g and screws g2 passing through the plate and betweerthe hangers into the seg ment, as in the Moyer machine. "lille seg ment is Inovabl mounted So that it can he shifted verticali on a central arm fr and two side arms h it" the front ends ci? Y. i are pivoted in slotted lugs h2 on tre side of the segment. The side arms il( are rigidly secured at their rear ends to n rock shaft H which is suitslly journalcd at its ends on the opposite sid, of the main frame, and the central arm n forked find has the rear ends of its two branches pivoted in lugs ha projecting upwardly from a har k* which is rigidly secured to the rear portion of the main frame and to which the rear ends of the key levers are pivoted. The segment-supporting arms are parallel and thus hold the segment upright in its normal and shifted positions.'

I represents a cam or cam lever for shifting the segment. This shifting cam is fixed centrally on a horizontal rock shaft z' and is provided with a. cani slot in which works a roller i journaled on a bracket i2 which is secured in any suitable way to and projects.

- forwardly from the middle of the segment.

The end portions of the cam slot are preferY ably substantially concentric with the axis of the cam so that. the segment will be locked from movement when the roller enters either of these end portions of the slot. The rock shaft z' is journaled at its ends on the sides of the main frame and has rigid .forwardly projecting arms at its opposite ends which rest on the upper rockenshapcd edges of shift key-levers i* fulcrumed et between their ends. One of the shift kcyievers is ruso?? shown in Fig. 1. B depressing the front end of either of the shift key-levers the rock Shaft and cam I are rocked with an accelerating motion and shift the segment, together with the type-bars and other' parts supported thereby, from the position shown in Fig. 1 to that shown in ig. 2. A 'suitable spring i", Fig. 6, on one end of the rock shaft i acts to start the rock shaft and cam from the shifted position as soon as the shift key-lever is released. lVhen the roller i passes out ofthe concentric end portion of the cam slot the weight of the segment and the parts thereon will force the cam back to its normal position. A spring (not shown) is usually employed to partially support the Weight of the shifting parts and reduce the exertion necessary to effect the shift. The location of the shift cam centrally under the shifting parts or substantially et the center of gravi ,y thereoimakes the shift'action quick and easy.

The segment is preferably mozmtcd and shifted as above described, but it could be dilercntly mounted and shifted by other means.

indicated by the shade lines in Figs. 1 hoth the central kcy-levcr F and the aesihai-y lever j are slightly oilset sidewise where they pass the shift cam to make room For tho movement of the cam between these closely arranged parts.

The universal bnr, as heretofore in the Moyer typewriter, consists of a rock shaft which is operated by one or more actuators which are strlick and moved by the typeliars they approach the platen. K K re resent the universal har actuators und L t 1e universal bar.

Two actuators K K are shown in the construction illustruted in Figs. 1--6 of the drawings. They consist of two curved bars arrnngcd over the pivotcd ends of the typehars so that cach actuator is adapted to be struck and actuated by any one of thc typchars on. the adjacent hull of the segment just hcorc the type-bar rcuches the platen. llach actuator is supported by two bars :l: It which nrc rigidly secured to und extend rearwardly from the actuator and ure pivoted to the upper ends of arms cz k extending upwnrdly und inwardly from n rock shaft L journulcd on the segment, for instance between the two pivot lugs 1* on the rear side of the segment. Tho inner supporting bars k v of the two actuators extend beyond thc m ms k2 k ot' the rock shnfts and are pivotully connected to the upper ends of lnlo; fw" which nrc suitably piv otcd ut their lower ends to thc roar cuds of brackets 'f. 'lhcse brackets arc rigidly sccurcd to und project rearwardly from the scgnwnt.

lak' represent springs for leturning the actuators to'the'normal position after actuationi Coil Springsave shown for this purpose connected at theirrear ends to the-actuator bars k lc and at their front ends to a bracket k secured to the segment.'

The universal bar L is prefcrabl` journaled onend pivots l l which are tiyxed by sa arms Z* to a supporting rodx l which is aiu ranged to slideendwise in bearings Z onrtheV undeiside'ofthe track casting B. -The supporting ban `is dctachably connected, for in4 stance, by av pin l, Fig. 6, with a. shifting 40 lever: or device (not'shown) whereby the universal bar `canf be readil adjusted endwise to either of four di erentl sitions. The pivots l'i l fory the universal ar preferably extend through guide holes in the l represents aspring for returning the universal bar to the normal ositiom Thev spring-shown connects one o the universal bar arms l to a bracket Z1 fixed to the sup- A orting rod l", so that the spring is not 'af` ected lby the adjustmentfof the universah bar. The universal bar o eratos the carringe escapement 1D prefera ly byan arm l"- which projects rearwardly from the universal barand is connected by a link l to the paw-l lever of 'the'carriage escapementn M represents the ribbon viln'atoror guide forivibrating the ink ribbon m to and from the printing position between the-typc-bars,l and the printing point of the plutem 'lhe vibrator, which may be of the construction shown or of any other suitable construction, is preferably arranged to reciprocate verticall4 on a stationary upright guide m- G and 1s connected Aatiitslower'end to a vibratingvorroperatjngi lever m. As shown, the vibrator guide m is rigidly secured by screws,ior:otherwise,^lto the front end of a forwardly pmjectin extension! ms of the track' casting B, an the vibrator M is confined'between'thelreartside of 4the guide m and a line-gage and center scale m* which is secured to the rear side |oit' the vibrator guide mi. The lower' ortion of theivibrator extends ddwnward y through aslot in the extension'im of the'track casting B and has a. rearwardly bent 'lower end whichremovably engagesna slot'in the front-end of the vibrator lever m2. The vibrator and its guide have'registerin :holes through which the'scaleonrthe scale ar m ofthe carriage can' be'seen, 'andthe vibrator is provided withl an'index or ointer m cooperating with said scalette in icate theposition of the printinpoint.A The upper ends of the viratorly vibrator guide m und thc-line gugef'm are'slotted centrally, as show-n, to allow the heads of the typebars to strike the-ribbon infinaking the impressions.

The vibr tor level' m is suitably fulprumed bet'cen its ends at fm.T on-the underfside of'thc rack casting B" and'is provided F its rear end with a toothed "segment wn.

etwcen this segment and its fulcrum the ever'is provided with an opening and a second toothedl segment m9. N represents lin arm rigidly secured to theuniveisal bar hud provided at its end with teeth which hre adapted-tig.' mesh with the toothed sevincnt `m, and 7i.- is an arm located at one si e of the arm Nand provided with offset teeth at its end adapted to enter the opening in the lever and mesh with the toothed segment m. Preferably the arms N' and n are separated by a spacing washer n', these three parts bein riveted to ether and rigidly sccured to -t ic universa bar by soldering 0r otherwise, and the arm N' is made in one piece with the esca ement actuating arm Z.

In the position o the-parts shown in Figs. 1 and 5, thc teeth'of the arm N mesh with the teeth m8 at thc rear endfof theI vibrator lover and when the machine is ofmrntcd the up cr'portion of the ribbon, orutheiupper fie d thereof, in thc case of a ribbon-having different fields, will be vibrated to and from thc printing position. By moving thc universal bar to the right. as viewed iu Fig. the tecth ofthe arm N are moved out of mesh with the Atceth'fm,tz of the vibrator lever 1211i and the teeth of thc other arm n are placed in mesh withthe other teeth m" ofthe vibrator lever'and thenthe lower portion or field of the ribbon will be vila-ated to and from the printing position when' the' machine is operated. If the universal bar is movedto the'left; to a lthird positionuthe vibrator lever is freed from both of the arms N- and' n' andi the-ribbom vibratory will." then-fremain inactiveqwlien the machine is 130 operated. thus permitting the cutting of stencils.

The lower ends of the arms Z l of the universal har are provided with cli-oss pieces or lateral extensions of sutticient width to be engaged by the actuator bars k 1 in either of the three positions of the universal bar just mentioned. If, however, the universal bar is moved still farther to the left, the lower ends of the arms l l aire moved out ot' line with the actuator bars k k', and then either of the actuators K can he moved rear'- wardly from above the type-bar hangers g so that the hangers cau be detached from the segment by loosening their securing screws and disconnecting the type-bars from their actuating'links without removing the clamping plate g for the hangers. The lower end of the actuating link Z for the escapement swings laterally when the uuiversal bar is shifted, but the movement thereof is not great enough to interfere with the perfecty action of the escapement in the three operating positions of the universal ba r.

Bv lo lating the escapement operating arm l o the universal bar over the rear portion of the top plate, as shown in Fig. l, providing the openings in the top plate. and detachably connecting,r the universal bar to its shifting device, the track casting B with the complete carriage, universal bar, escapcment and ribbon vibrating mechanism can be detached from the top plate. by simply removing the securixw screws for the casting. detaching the rilil-ion from the vibrator,

and disconnecting,Y the drawband 'n thatt connects the carriage to its spring drivin, r drum. This is a great com'enir-nce in assembling. cltaniugr and rcpairinar the machine. and in changing it for carriages of diti'crcnt lengths. lt will be observml that the universal bar is not connected to the actuators on the segment and consequentljv V.

there are no parts requiring to be disconnected to permit the removal ot' the top plate or the track casting with the parts supported by the same.

The ribbon feeding and reversing mechanism form no part of this invention and are thcrct'orc not shown or dcscribcl. bnt. this mechanism is mountcdus heretofore. en the, top plate Il, and as the ribbon spiols and the kvibrating mechanism arc also zszonntcil on thc top plate, as shown. it, wilt llc erident that the top plate with the complete ribbon operating mechanism, together with the. other parts mounted on the top plate, can be removed from the machine by simply dctachinfr the top plate and without disconnecting any other parts.

0 represents a center guide for properly guiding` the type-bars to the printing point` on the platen. The center guide is secured by screws, or otherwise. to an upwardly projecting horn or extension o on the middle 'material to the rear far enough torperniit the detach ment of the type-bar hangers from the seg ment` as before explained, yThe center guide t) extends upwardly and forwardly from the segzment to a point in front of the lower end of the vibrator guide mf, then rcrticelly in front of thel latter, and its reduced upper end o extends rearwardly into the slotted upper end of the vibrate-r guide. 'this opper yend o of the renter guide is slotted to receive the guiding heels or parts 02 at the enter ends of the type-bars, The center guide. which shifts with the segment (7 has an elongated opening of' to enahle the scale bar m5 to be seen through the openingsl of the rihbon vibrator M and its raide an either position o the center guide, and the center snide also has it larger .eniug o* below the opening ai' that adams the toi-fer end of the vibrator gahl the vihratm', and the front end of the vi tor lever m when the center guide in n raislrt or shifted! position. W'hile the center guide t) shifts? with and thus always retains the sana, rela@ tion to the typedxars.y the vibrator guide fm." station/ary and remains in the same retav tion to the vibrator M.

P represents a VbachV .st-frio, or rest, for sapY porting the outer ends of the typebars in the. normal position thereof. This back stop is also supported from the segment so as to shift therewith, for i stance. by posts ,n which are rigidly secured to the ends of the segment in any convenient. way and project tornardiy tlnfrefrom. The back stop or resty as shown in Figi. i. preferably consists of a chain com nosed of center hleclts and side links pivota ly connected by rivets, and is provided with a tap strip 0i' pad p" of teather or other suitable noise-preventing The hlocl's and links meet on radial lines with only eiiongxh clearance to permit a very limited movement thereof on the rivets,` so that the haclcstop or reet rctains a segmental torni and only a limited `tla-ia'iiig thereof is permitted'. tthe end blocks Il il it is srtnck by the returning type-har tends to straightenthc chain at. both 4'sides of that point. and this transmita a slight impulse to Some of the adjacent typedars no' tlpat their inertia is added to that of the chain to absorb the shock. The result is that the tendency of the type-bars to rebound is practi cally overcome.

Figs. 7 and 8 show'a modified const rueticn of thesegment, and universal bar met-hir nism which is less expensive than that before described. In this (xmsti'uetion, (i represents the segment. The type-bars E arc pivoted on the segment by a curved pivot Wire G, thereby dispensing with the separate hangers and bearings used in the first construction. A single curved universal nar actuator K is used which is long enough to be struck by all of the typebars. It is supported by two rock-shafts g q' journaled one in rear of the other in brackets gt projecting rearwardly from the segment G and having upright arms g and q, respectively, which are pivoted to supporting bars q5 projecting rearwardly from the actuator K. The universal bar L has a single pendant arm y pivoted to the rear end of a link q1 which at its front end has a pin and slot connection gs with a bracket q on the actuator, The pivot between the link and the actuator normally occupies a position below tlnl level of the pivot between the lilik and the arm q, and when the segment is shifted the former pivot occupies a position a corresponding i .stanco above that level, so that the action of the escapement and of the ribbon vibrator will be the same in both the normal and shifted positions of the segment. The pin and slot connection Q allows the actuator to return to normal position in ad vauro of the return of the universal bar. and the connections at the ends of the link are loose enough to permit the universal bar to be moved to change the throw of the ribbon vibrator as before described, without affecting the action of the universal bar. This segment is mounted and oierated in the same Way as that first descri ed and, as in theA first construction, the universal har actuator, thet center guide O' fox-'the type-bars, and the back sto P for the type-bars are supported by and s ift with the segment. The segment and the parts supported thereby with but slight changes in one or two of the parts, are interchangeable with the corresponda arts in the construction first described? his modified construction is less dcsirabie vthan that first described, but it involves a a carriage escapem nt, a series of vided mth a plurality of sets ef type, the

invention is not necessarily restricted in a pliration to a machine having such a shi table segment as it is desirable for some purposes to support the escapement actuating means 0n a ment which does not shift whether provi( ed with type-bars inning a single set of type. or more than one set of type and used with a shifting l laten.
