ir: ihr construction shown in Figs. 1.--9. i' snppnrt (fl is pivoted to the. frantenilz; o? vo pairs of arms 57 g' which are 1' 'n nl resneetivffly lto rock" shafts g2. g5 mounted in reinc-a-n'frizl 'portion of the bridge a;

site sides of the main frame. The hanger support G can be shifted by any suitable means, such, for instance.I a cam lever g* adapted to be rocked by a shiftin key g5 and acting on a roller or port y suitably attached to the support. The sgort or plate G is preferably stamped from stock of suitable thickness and as rearwardly bent pivot lugs g by which'it is pivoted to the supporting arms. gs indicates openings in the ends of the'plate G in which are secured supporting rods, not shown1 for the type-rest. rrheplate G is preferirblygrooved on its rear side to receive the heads of securing screws It for the type-har hangers H H H2 H3. The groove for the securing screws for the central hanv'ers is shown at h', Fig. 1, and the grooves or the screws of the remaining hangers are indicated by dotted lines in said figure. The plate is thus grooved to reduce its thickness, so that the whole series of oblong holes la, through which the securing screws for the hangers pass, may be punched at one operation. The holes for two extra. outside hangers are shown at h3, Fig. 7, these hangers being omitted. The other holes are of similar shape.- The front face of the plate G is plain or flat. The grooves k for the screw heads and the slots through which .the screws pass are large enough to permit e limited vertical movement of the screws therein, sufficient for alining the type.

In the construction shown in Figs. 1.473, the hangers H H H2 an H3 have bodies or attaching portionswv there secured in 'upright position, paralgl witheach other, on the supporting plat-e G, and bearing ends which nre bent at the' necessary inclinations taille body portions to permit theA typehsars to swing in radial planes and make the impressions at e connnon point on the` platen. The bodies of all of the hangers are of uniform thickness sufiicient 'to pro vide the required space between the typewbsrs when the hangers are secured face to face on the support` and by mnl-.Iii'ig' their 'nearing ends of appropriate lengths to locete the hearings in :in nrc7 as shown. the required spaces between the hearing ends are secured, such spaces increasing in width from the center toward the ends of the se ries. This increasing?l space is required to accommodate the increasing,r o'i'set or inclination given to the heads of the typehars to enable them to nest properly in the type-bar basket. The hangers may 'be formed from stock which is rolled in two dilerent thicknesses, suitable for the body and nearing portions of the hangers, or the bearing ends may be reduced in thickness by swaging or machining. The hangers ere arranged in a central group and two side groups at each end of the central group, and are clamped together by screws z' e" i2 ie as presently explained. The hangers are made in pairs,.or rights and lefts, and with bodies of two' difieren-t forms., as shown in Figs. 5 .and S. The hangers H hnvescrew threaded holes il (see Fig. (i) -in their bodies; the hangers H2 have similar thread ed holes at their lower ends, and the end hangers il? of the several groups against which the heads of the, clamping screws bear, have smooth holes slightly. smaller than the screw heads through which the screws pass. The remaining hangers H all have two open-ended slotsl ld, as shown in Fig. 5, for the passage of the ,clamping screws. The clamping screws are of four dili'erent lengths. The screws z' and i' ex tend through the hangers of the two side groups at each end of the series and have threaded ends screwed into the threadedl holes in the hangers H. rhe screw i2 passes through the center and. adjh'cent side groups and has a threaded end Ascrewed into the threaded hole in the hanger H2 of' one side group, and the other screw z" passes through the hangers of the central group and is simi l'sirly screwed into the hanger H2 et the end of this group. The securing screws k are screwed into holes in the rear edges of the hangersthe holes being staggered to make room for the screw heads, as indicated by the dotted lines in Fig. 7.

In assembling the hangers, after the typebars here been pivotally secured thereto and the operating links connected to the typehars, the han ers are secured loosely on the supporting p ate G by the screws ll, after which the plate G is pivotally connected to its supporting arms and the operating links connected to the upper ends of the actuating levers. The clamping screws --c'a are not screwed in tightly until after the type-bars are elined, but they are screwed in far enough to create sullicient friction between the hangers to hold themegdinst accidental moiyement .while being alined. As fast ns the several bars are alined the hangers ther lor :ire locked to theI plate G by the screws if., and when all of the type-bars have been properly elined' the several clamping screws -za are screwed in with suflicient force to rigidly chimp the whole series of hangers together thus makin a more rigid and reliable connection of t e hangers to the support tha/n is possible with hangers independently secured within the same space. Any one of the hangers H having the open slots een be detached whenever this may beneeessary, by first removing securing screw la und loosening the two clamping screws which pass through that hanger dis- :i-.finnecting its link from the auxiliary lever and pulling the hanger straight outwardly to the front. In the case of the hangers -H .and H2 having the threaded holes for the clamping screws, it is necessary te remove misst-ss the clamping screws also. ln any any desired han-gers can be letacnez'l and replaced without. disturbing the others. A convenient way to assemble the hangers is to first loosely clamp together by the screws il the t, rs of the central group, than loosely clamp together the nine hangers at each. of the two side Agroups by tue tue short screws i z". The iye groups are then placed together and loosely clamped by the screw i2., This is allv done before securing the grouped hangers on the supporting plate G. The hangers Construct-edA and arranged in this manner may cost slightly more t-o-produce thansome'forms of hangers now in useA` which are arranged inradial lineson their support5 but the support (l is less expensive than one made for radially :arranged hang ers, sotliat lthe total cost is about the same. But an 'absolutely Arigid' support for the type-bars is produced and the hf-ingers cannot become loose by reason of side s lus causedl byv CollisionsA between .the typwmrs. and so much time' is saved in alining the type that the described construction-is in reality much less costly than other ronstructions of comparativefvaluel vTl e :great advantage gained in alining the type will he readily appreciated; when it is' understood that any 'of the type" may-be raised or lowered vertically at 'right angles. to the print ing linewi'thoiitua'ffecting the lateral position of the type at-the printing point, oy simply adjust-ing'the'hangers" vertically up or down. `The wholeseries'of type-bars can be properly alined with the 'same ease and speed thatis ordinarily required to aline the central bar yinj rnaelinesA ha'ing )radial hangers. Thusnot only is there an important saving' in t'inie'of the' most expensive labor required vin the' manufacture of 'type writers, but the Work canbe performed .with labor of less skill and consei-piently more economically.v 'y s Ball bearings of the usual forms are not suitable for vpivoting thel type-liars to the hangers, since the hangers arranged in parallel planes within the small space 'shown do not afford sufficient room.A Therefore, haying especial-reference 'to the described coustruction of the hangers, the bearings are preferably constructed :rs follows: The hearing'emlof each hangerismaehined to form a low cone frustum Kpn one'side thereof and `is rovided with a relatively large ceuA tral ho e c. Tlieoppositejsirle of thelianger isl counterbor'ed and lsfzr'fwi-"tlireaflral, as show-n at lcx Fig. 2, -tu receive a serre:- threaded adjusting plate le: for an adjust able cone its which' is serur-:d to the plate by a central screw /c having a head lorated in a. cou'nterliore in the adjustingr plate/c3. The adjustable cone k3 has a projecting shank which enters the linie tu: holtazul shankl being 'circular mth dat sides` or of ether shape adapted to preventtle eene from turning in the hole. The inner end of earh typeliar is made with fan internal .annulas' ball race or groove and a. circular 'row ot' halls .t5 is confined-between this race and the balls, or until the adjustable .cone acting,-

with the fixed cone has forced the halls into the race inthe type-bar so as to prey-ent. looseness. Then the parts aie locked by srrewing in the locking-screw 1* with ftonsideralile force. Y. Y

Should the bearing be-sti it only nee-- -ry to unloelr-itandscrew in th ad justing plate It? slightly: and again los-lr .itA as before. As the shank oyt'ne adjustable eene is held from turning inthe cone it is evident that theadjust-ing vplate is held against turning in its seat when the locking screw is screwed in tightly. Y The adjust'- ing plate 1? is made with slots cris. otlrexy wise formed Vfor the enragenient of a tool for turning it., and it is'msopreerably split as shown` and slightly- Vexpanded*so thstritls to .be connu-esseri somewhat tovsere'fv it into place. This causes sulcientt'rition to prevent accidental movement (1f-the plate'ihen it is uuloelech llhisibesring is easy to re adjust to take up wear after use, by unloele ing the sereiv 14, ye .slightly unsereirar the adjusting plate and reloclring, as lie fore. l ,i

As the meeting plane e -ot the edil ing lplate and adiiustable' C 'one- :s flat against each `otherin a' planeperpendi =lar to the axis of the bearing', tlievadiustaiale.

cone must be held at alljtimes parallel vwith the' lixcd cone, assuming of course that the adjustinpr plate kf is l properly*fitted in the hanger, und it 'ill be apparent that, owing to the relatively large diameter sai-the adjusting plate anyslight misfit iu this part will be much less serious than, it'- a smaller sewn-tl:rrzuled part was depends:l en to hohl the cones parallel. lt has beenveund extremely dificult tumultesmall ball lpesrings of 'this nature that dependen sereuhthrladed partis to hold one cone concentric with the Uthman-ith -sulicieut accuracy on a rouunereat scale.l

ln the abose construction both the adjusting plate andthe lock seri-.w 5* may se m'fceutric to the 1cones without objectitm lin this respect. Greater depemlrnce ceuul be plat-cd ou Vaecurate ittin; ,Y ofthe cone exension in the hanger` and exact central lo- Ijfzlion of the hole to receive it` than te screw 'i-r cone extension into the fixed cone as has been done b v others. Preferably, however, the cone extension is lfitted loosely in the fixed cone. as shown. and the balls are relied upon to force theadjustable cone into proper roncentric relation to the fixed cone when adjusting the bearing. The balls naturally do this if a littl.. Care is used in making the adjustment, and, vwhen locked, the adjustable cone will retain its position. ln either case the trouble caused by a loose or eccentric locking screw is overcome, as the only funetion'of the screw le* is to rigidly lock the adjustable cone to the adjustin '"plate.

'Il machining the hangers to form the fixed bearing cones K. a small flange or dust guard k' is preferably left on the upper end of the. hanger which overhangs the space between the hanger and the vtype-bar at the upper rear portion of the bearing. The universal bar hereinafter described extends over.

these guards on the several hangers, so that the guards prevent any dust that may fall behind the universal bar from entering the bearings. l

L represents a curved universal bar which is substantially parallel with the are of the type-bar bearings and is supported over the bea rings in position to be struck by the typebars as they approach the platen. preferably in the. following manner: M represents a bar which is' secured. for instance, by screws m to lugs m. ou the upper central part of the plate (l and is provided at its ends with cross arms m?. ln the front and rear ends of these. arms, parallel rock shafts 'mil m* are journaled which are provided with rigid dependingI arms m. 'lhe universal bar has fixed thereto rearwardly extending; arms m which are pivoted to the said depending rock arms 'mf". The universal bar is thus hung so that it is adapted to be n'ioved rearwardly when strurlc by any one of the type bars. .X suitable spring,r m7 arts to restore the universal bar to its forward or normal position. 'lhe spring: shown is connected at opposite ends to an arm m, on the rock shaft m3 aud to an arin lm" on one leg ol' the renter guide. for the type-bars hereinafter described The universal bar is connected te: the carriage escapement for aetuating it. preferably as follows: N represents a nearly horirontal link pivoted at its front end t0 the rot-k arm me and at its rear end to the depending arm of a bell crank lever u which has a rearwardly extending arm ronnerted by a rod n' to the rontrollinv lever Il of the Carriage esen pement. The bell crank lever n, is pivoted on a bracket n secured to the supporting bridge for the carriage track. As the carriage escapement is mounted on .a fixed part of the machine while the universal bar is mounted on the shifting supporting plate G, the link N is pivoted to the bell crank n m a plane midway between the normal and shifted positions of the pivot which connects the link-to the arm nr. so that the action of the escapement will be the. same in both positions of the supporting plate G. By these connections the escapexnent wheel is released every time the universal bar is moved rearwardly by a type-bar, and the spring m acts to restore the eseapement lever as wellv as the universal har to the normal posit-ion.

0 represents the vibrating ribbon guide or vibrator, which may be constructed and mounted in any suitable Way. The vibrator shown has ears o by which itis slidabl retained on a stationary renter `duide for the tvpe-bars and it is pivoted at its lower end to the front end of a. vibrator lever Q. The center guide shown has downwardly and rearwardly extending: legs p rigidly secured to the bar W. preferably by the seturing;r screws fortliis bar. The center guide slides up or down in front of the vibrator when the type-bars are shifted to different printing: relations to the platen and always retains a fixed positionrelativix to the typebars. The vibrator 0 also actuated b v the universal bar through mechanism,which. as shown in Figs. 19, is instructed as follows: 1' and r'- represent two arms of diferent lengths which project 'from a hub R loosely sleeved on the central part of the rock Shaft m. A nut ''2 screwed on the shaft 'ms and bearing against the hub of the arms r r' retains a tapered stud 'r3 on the rock arm m8 in a hole in the arm r. whereby the arms r, 'r' are locked to the rock shaft mi so that they will be rocked when the 'aniV` versal bar is actuated. vWhen it is desired to silence the vibrator, the nut r2 is am screwed', when a spring?A between the arms m and r will disengage the. latter arm from the stud 1". to the rock shaft by again screwing; np the nut r2,

S represents Aa link arranged with its front. end between the arms -r fr" and extend;

To vibrate the lower iield it is only necessary to push in the sleeve .u as far as it will go, which, owing to the contacting ends of the springs e, pushes the other sleeve r out of locking position and releases the arm U at the salue time that the arm U is locked to .the shaft m3. In order to silence the vibratoiit is only necessary to withdraw the locking pin from whichever arm may be in use, without pushing in the other locking pin. Both arms U and U' with the links u2 y11.3 vibrate 'together at all times when either arm is looked to the shaft mx", and whichever arm is locked controls the more` ment of the other arni through the arms The pivots at the ends of the links 112 and u3 are located in the same positions as the four pins that connect the link S with the arms r T' and s s in the lirst construction, and the same result is accomplished in both cases.
