The rear ball 27 is confinedbetween a pin groove -6-and an abutment 32 e hinge end ofthe se meat 13'; while the lower ba 1 28 is confined tween a pin 33 in the groove 6 and the abrupt terminal 24 of the groove 23. Thus the play-of the balls is limited, and they are kept separated at substantially equal interva s, so as to afi'ord a firm-support for the type bar all around the bar 3; llgarlic by means of the screw 16 the ball-be "Mg joint may be made so tight as to prevent either longitudinal or lateral shake of the bar ;vvitiioi1t=,p1'eve1it--' ing 'the free swinging mo ement thereof to The type bar is assembled upon the curved supportmgbar 3 before the screw 16 is mserted, the hinged eye-segment or flap 13 being open so that the maln'eye-se inent 12 may be dropped over the disk 7 .g, he balls having been placed in position, the hinge, p 13 1s closed, and its hasp' 15 is secured to shank B'by screw 16, the latter being ad- 'usted until the requisite tightness of the all bearing joint is obtained. j It \iiiil be perceived that type bars may-be made cheaply and assembled with cascand rapidity; that'the type is accurately guided to the t pe desired, and readil printingcenter;'that the screws 16 may be adjusted from time to time to take. up play arisin from wear or, otherwise; that any an may be instantly detached when reassembled, without 'r'eferenceto any ot er type bar; andv that the bar 3' cannot spring durin the printin strokes of the type bars. b g

. {It will be seen that upon the curved or segmental bar 3 are formed radial converging" staggered exterior circular bearings arrangedsslde by, side and that the type bars are directly -hungs1de by side u-pon said grooves 6 with the interior eye-grooves each other; that thesection 12, "formedintegrally-with the shank 8 of the I prefer to ofi'setor sta ger it'tlll'BCtiOIl longitudina ly of type bars when the latter are at rest, still 1 do not I seems bearings, the annular grooves upon the se ment being encircled by 'the interior y grooved type bar hubs; that the grooves upon the segments are ailfstautially cundistant i'J-onn the printing center, but oi set one from another forwardly and rear wardly; that the. downwardl curving segment 3 forms substantially li alf of a ring and is arranged forwardly of the platen and hung by its ends upon the framing of the ,machine, and is provided with two sets of bearings, those in one set being forward of.

those in the other set and having a staggeringhor alternate. arrangen'ient with reference thereto; that each type bar hub is composed of separate segmental interior-1y grooved sections, the 'hasp 15 and screw 16 being provided for-huh ing the sections together;

that the grooves 6 form pivotal" bearings for the type bars, and have a common 1nternal support consisting of the body of the bar-3; that means are provided for adjusting the type bar hubs to said grooves or bearin s; that in each type bar the segmenta hub sections 12.and 13, taken together, form an incomplete ring, theserew 16 serving to draw the ends thereof toward which is type bar, forms substantially half of the hub, the section 13 being hingedthereto at a point opposite the junction of the hub and shank, the screw '16 serving to bind the 'unthe section 13 to the section hinged end of 12; andithat the segmental or segmentshaped .ball bearing groove 23 has abrupt terminations 24 and 25,.which limit the excursions ofthe ball 28 placed therein.

While I prefer to alternate or stagger. the disks or bearings 7 as shown, still the in vention includes disks, which are offset one from another,whethe r or not they have a uniform staggering arrangement and while '1 hearings in wish to limit the invention to this particular ,direction for the oifsetting in so far as certain features ofmy invention are-concerned. .It will be seen that the type'bars are-seginentally arranged in two series, the type bars of each series having their pivotal centers situated in a plane that is at an angle toa horizontal plane, or in other words, the

type bar pivot centers of each set are ar ranged in a vertical plane extending transverscly of the machine, that the two planes in which. the pivotal centers of the t pe bars 1 are located are parallel'to each ot ier, and that the pivotal centers-of the type bars are alternately sta gered fore-and aft of the machine. Whi e I prefer to use type bars such as illustrated, otherkihds ofitypebars may be employed, if desired, in connection with the novel forins of bearings. 'While sans H i prefer hinge of the, segmental I u i 's'pctions to the other, still the hub sections maybe otherwise attached and otherwise formed within the scope of the inventioin v fl t l1ile I ,prefer to adjust the hubs of the type b'ars so as to'secure a. close fit of the pelbarjupon' the hanger, other provision or adjnstment ma ,be made, orif desired, ,Qthere maybe no a justment. ",While I prefer to. insert anti-friction balls between the hired bearings and the type bar hubs, still, soifajr as certain novel features of the iiwen:

tion are eoncerned,fballs may be omitted.

:3 a9, 7 Although I show the'type bars hung upon a setof hangers formed integral upon 'a sin-,

' gle bar, still it is obvious that many impor- "tant'features of the invention r'elatingtothe I type-bar per se may .be em floy'ed in type bar joints Where the type barsare hun upon tleta'cliahlymounted hangers. It is a so ap- 'ij' p'arent that certain of the novel features d1s i closed herein may be used upon either the type bar or the ban er, as desired,.such use ltt'involving a reversa .of the parts; for in v s'tance,"so' long as one, of the hanger and gtype bar elements has an exterior annular groove and the other'thereof is composed of attached segmental interiorly-grooved se c 'tions, it is immaterial which part has the ex torior groove or which part is divided into "interiorly grooved sections. i-S'olong as the" outer hearing is in the form of an incomplete "ring,-it isnot essential that said ring-be ad- 69 ditionally divided into hinged or attached "*Se'ctiOna's fa-r as certain features'of my inventionf are concerned, since in either case- Y the screwlti may be employed for drawing I 'the ring ends toward each other and placing 'the partsunder spring tension to automatici a1ly:ta'keupany wea'r'that may occur. I blievefmyself tobe-thefirst to place a plurality of offset converging bearings side yside and eneircle them by type bar hubs,

with or without hearing balls.

The purpose ofimaking the arm or hasp 15 thin andlong .isto render itslightly flexi- 1 ble or elastic,- so that when the hub segments .of-the type-bar-aredrawn toward eachother :65 by,.the screw v 16, the hasp may be sprung.

I prefer to form the, offset or stagger by the, type barhubs. WhiIe YI illustrate a the 'radius may vary as desired. The

Many other changes in "details of construction and arrangement may be resorted" to within the"scope"'of the invention, and'parts of-my improvements may be 'used without'othe'rs.
