To ch fev/rom it may concern:

.lie it known that l., lowiN E. Banner, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type-Tits ing Machines, of which the following is a specification.

My invention relates to typewriting inaparticularly to the type bars and hangers therefor, and the object of inyil'ivention is to provide a simple, easyand efficientl type bar bearingby which the type bars are guided against. lateral defiection in the printing l'novenicnts thereof and wherein there is little liability of undue alineinent is provided.

To these and otherends which will hereinafter appear, the invention consists in the features of construction, arrangements of parts and combinations of devices l,hereinafter described`and-more particularly pointed out in the appended claims.

In the accompanyi-nfgg drawil'igs, wherein like reference numerals'designate like parts in the various views, Figure .l is a front to rear vertical. sectional View of sufficientnumber of parts of a typewriting .machine to illustrate my invention. Fig. 2 is an enlarged detail fragmentary sectional view of a type bar and hanger the section being taken on the line of Fig. 3 and looking' in the direction of the arrow at said line. llig. 3 is a transverse sectional view taken ou the line i/- of Fig. 2, looking in the dirertii-ni of the arrow at said line but showing` bars. Fig. 4 is au enlarged detail side view of one of the bearing disks. Fig. 5 is an enlarged detail side view of one of the type bar hangers. Fig. (3 is a vertical sectional view taken on the line of Fig'. l, and looking in the direction of the arr'ow at said line; the view illustrating' in .front elevation the type bar segment aud soule of the type bars and hangers. the ti- Vpe bars being' shownin section. Fia'. T is a fragmentary front elcvation of au alternativ/.2 construction of sog nient and hanger, the type bars being` in section. Fig'. is a detail side sectional elevation ol the Same.

The traine of the machine comprises a hase l.. corner posts-2 and top plate A carriage not shown) is niountfal above the l top plate and carries a platen ft. Key levers 5 are pivoted in the base of the machine at t3 and are provided with the usual finger keys 7 and restoringl springs Se levers t) are pivoted at 10 to the key levers and 6o are each provided with a slot ll in the lower end portion thereof for the reception of a fixed fulcruni rod l2 which extends beneath the key levers and'froin side to Side of the machine. The upper end of each sub-leveris pivoted at i3 to a forwardly extendin.;l link 1+i which has its forward end pivoted at 15 to a type bar lo.

Each type bar is preferably made of three pieces, a body portion andtwo irnlelieiulent- 7o cheek plates 17 which latter may be stamped out or formed from sheet metal and are located on opposite sides of the bar and se` cured thereto preferably by rivets '18, thusl forming a bifurcatied portion atthe pivotal end of the type bar i'orreceiving a type bar hanger 1S), preferably made of'sheet metal and with smooth or lapped sides. 'By inaking the cheek plates 17 of separate pieccs Iam enabled to smooth or polish or lap their inner parallel bearing' faces before theyv are attached to the bodior shank of the type bar and so that they will '.zoipcrate with the smooth sides of the hanger with the mini .n'nun amount. of friction, thus conducing to 85 the greatest freedom of action of the type bar. lf desired, these plaies may be hardened and united to the type bar by soft rivets` 18. 'l`he hanger l5) has an eye 2t) which is received within the bifurcated por 9G tion of the type bar, and a dish. or collar 2l with a periphera bearingV face. or edge 2t! isseated in the bearingl of the eve 2t). The disk Qi has its peripheral bearing` sur- ,Y face cut away or apcrtured at. 2l so as toit??? provide openings .or recesses that extend transversely through the dish. When the disk is seated within the eye 2() and the eye is properly positioned Within the bifurcated portion fornuid by the cheek plates lT of inc 10J type liar. rivets 525 ma): be inserted thro 1gb coiimiding.;I openings in therheck plates which register with the openings tl in the bearing dish and the ri vets may be upset or headed on the outer faces of therheek plates in or 105 der to' maintain the parts assembled and the .type bar and hanger united as shown. '.lhe-

rivets are of such diameter that they do not till the openings :'Ltnd are situated so that.

they do not contact with the inner bearing iw surface 23` in the eye of the hanger. The disk 21 is preferably inade from one-quan ter (1/4) to one-half (1./2)` a thousandth of an inch thicker than the hanger, in order to prevent the cheek plates'froin pressing unduly. against the side bearings or faces" of the hanger When the rivets are upset or headed in assembling the parts, thus en l abling the bars to Work freely. It should be understood, however, that the slight exs cess of thickness of the bearing kdisk does not preclude the cheek.` plates from being set close enough to the sides of the eye of the hanger to prevent any lateral shake or inovement of the type bar relatively to its hanger.

By extending the rivets 25 through the apertures 24 in the bearingA disk in the Inanner shown, the rivets interlock with the type bar and bearing disk and the latter is positively connected to and obliged to turn with the type bar; the rivets being offset from or arranged on opposite 'sides of the center of the bearing `disk or collar and a shearing strain bein exerted by the rivets on the disk. Furt ermore, it will be seen that the rivets 25 extend through 'the disk at or near.

the peripheral bearing 22 of the disk so that the rivets are enabled to turn the disk with the best possible leverage When the 'type'bar is operated.

The eye portion of the hanger may be comparatively large and the cheek plates comparatively broad so as to provide suitable side bearings for the type bar and prevent as inuch as possible lateral shake or detlection of the bar during its printing` movement; the Wider or broader these side bearings are made the steadierand truer will the baroperate, but at the same time these side bearings inust not be so large as to cause undue friction, and again pressure between the cheek plates and the eye portion of the hanger should be avoided so as not to interfere with the freely swinging movements of the type bar. .l the cheek plates 'ust contact with the eye portion of the liangei or substantially so, without pressing thereupon, the best results are obtainable. Preferably the rivets are headedby a spinning operation instead of by hammering, so as' to avoid capping the cheek plates and causiiifr thein to press against the eye portion oi' the hanger and also causing them to lose their parallelism, for in practice the inner surfaces of the cheek platesl should be parallel with each other and with the sides of the hanger, and they, a'sivell as the sides of the hanger, should be smooth and even to get the best results. The disk or bearing :il may be of any suitable diameter and hence -of such size as to provide a coinl'iarativcly large and durable pivotal bearing for the type bar. l The openings 24 inthe peripheral hearing .of each disk, are slightly larger than the diameter of the rivets contained therein as clearly indicated in Fig. 4, vand constitute recesses which will collect any particles ot dirt or 4metal that niaybecome disengaged from the bearings, thus preventing their working into the close fitting parts and which would result in a` cutting ot the bearings and in producing undue friction he tween the type nar and hanger. 'l`he said recesses may also act. as cups to hold -aud supply a lubricant tothe bearing.

It will be seen that lhc construction is such that a closejoint is formed between cach type bar and hanger and that it is ditiiculi' for any dust', grit or rubbings that may drop from the front faceol the platen to gain access to the pivotal bearings ot? the type bars.

Each hanger is provided with a depemb ing stein 2t) which has a rear bearing edgel 27, and also a. bearing shoulder or edge 2h that extends at right angles to the bearing edge 27. A forwardly extending,r car 2S) is perforated at 3() for attael'nnent otono end of a coiled restoring spring 3l, the other end of said spring being connected to the 'type har at 32. l

A type bar segment 33 has radial grooves or slots 34 in the front face thereof, and

horizontally disposed grooves or slots l5 are formed in the upper face ot the segment 5 the horizontal :dots alining with 4the slots in the front face of the segnn'nt. so that the horizontal and radial slots are arranged in pairs, one slot extending al. an angle lo thiother an'd cach pair of slots being adapted lo receive a hanger.

It will be seen that the bottom wall 3o ol each slot. 34 in the front tace o," the segment is at substantially right angles to the bottom wall 37 of thel associated slot in the top olI the segment. 'I`he stem 21' of each hanger is received within a radial slot Il-l in the t'roul face of the segment and extends sub lantially throughout the length olI said sloh and the bearing edge 2T ot' the stein titl is seated against the bottom wall lt in thil slol 34 in which tln` hanger is seated. 'l`he parl 2S ol the hanger is received within the alined horizontal slot 35 und hears against the bottoni wall il? ol' said horizontal slot.

lt \vill be seen that `by this construction a twisting niovenu-nt ol the hanger around llu` longitudinal axis olf its stem is prevented and the hanger is properly positioned by the walls ot' its l-iorizonlal Islot l, whereas tlul associatwl slot -ll in the l'ront linee oi' the segment contains the stein 24' throughout its length and properly positions thc hanger in aradial direi-lion and prevents :in v sidowise movement oll llustem ol' the hanger. i\ -set screwtltw is provided foi-each hanger and is received 4within a threayled opening lfl in the froiil face of the segment und al a slot 34 therein and said screw bears at its llll'i llt) . the hanger would come at tit) assess rear end against the inclined edge a0 of its associated'hanger and secures it in position in the slotted segment and together with the Walls of the slot prevents any movement of the hanger in any direction. By providing' slots in the segment at right angles to each other and providing cooperating portions on the hangers which yare seated in said slots and extend at right angles to each other, the hangers are properly positioned and guided against lateral movement or twisting in any direction, and an accurate positioning of the hangers may be secured and maintained.

VIt has been found in practice that without the slots there is a tendency for the hanger to twist-or move out of proper radial position when the. set screw is driven home, provided there be the slightest looseness or play between the hanger and the sides of the radial slot l3st-, and provided also the axis of the screw does `not enter or register accurately with the longitudinal center line of the hanger and which would enable the screw to force the hanger sidewise or twist it in such manner that the rear edge 27 of an angleto the rear wall of the slot 34, whereas it' should be parallel and in contact for the full length of the stein or shank ot the hanger. lt will be understood, of course, that if the hanger be thus twisted or turned aside from the true position the type end otl the type bar will bey thrown out oi' proper radial position and the type will not print in alinement. l'iut by providing the slots 35 in the segment and seating the shoulders 28 therein, the screws are unabletotwist the hangers or move them ont of proper radial position.

That portion ot' thc segnicnt wherein the tapped holes -fi lorthe screws are provided is niade or torined in the nature of a forwardly projecting flange Sii-i, while the body orfircb portion 243i ol thisl segment .is arranged in rear ot said lial'lge portion Z'il lleretoforc thtl radial slots for receiving' the hangers ha\e heen inadc only in the said flange portion ihr and these were i'ound to bc insnliicicnt to maintain thc hangers prop orly in their radial positions when the reA tainingl screws were tightened up.

it will bc observed that l have provided not only the horizontal slots or grooves 35 but that l have also cut, the radial grooves -t entirely beyond the flange and into the body or web olI thc scgnient, and at the same time l hare made these grooves in the body or web portion longer than the grooves in the flangiportion and have ilicreascd the lengths o'tI thtl hangt-rs correspondingly, this' increased length ol' both grooves and hangl ers reducing"liability o'lA twisting' or lateral motion ot the hangers to the minimum.

The radial groovcswhich extend through andwbcyond the tlangc into the body or web Of the segincnt have been designated of the segment.

at right angles to each other,

V type ha r and unite the rotation between said disk and for the reception of the hangers constituteone set of grooves and the grooves in the web or body constitute another set of grooves. The last mentioned set oflgrooves are represented in Fig. 6 by the reference ttl,

The grooves 35 are n the same radial planes as the grooves 34 although they are cut at'right anglesto the latter and parallel with the axis of the internal cylindrical face In Figs. 7 and 8 have shown a preferred form of construction embodying my invention. ,ln these figures I have illustrated a hanger 19, similar to that previously described except that said hanger is provided with a shoulder atl that extends at'an angle to the bottom Walls of both slots v34 and in which the hanger is received, and .a set screw 38a is disposed in an inclined position and is received within a threaded opening 39 in the segment Aand bears at its'inner end against the shon'lfder 4l on the hanger. A pressure exerted by. the screw 38a on its 'hanger will force it lboth downwardly and rearwardly until both bearing faces of the hanger, which are at l right angles to' each other, are firmly seated against the bottom walls 36 and 37 of their slots, which are also thus firmly seating and securing the type bar hanger in place. c v
