' Application flled'flarch 16, 1903. Serial'No. 149,050.

Be it known that I, ZALMON G. snows,

citizen of the United Statesyand resident of' Evanston, in the countyof Cookand- State of Illinois, have invented certain new and use- -ful Improvements in Type-Writing Ma'- chines, of which the followlng is a specification. r My invention relates to typewriting machines and more particularly to the type-' actions for visible Writing machines, and one of the mam ObjGCtS of said 1nvent1on 1s to provide a rapid, efficient and easy type-ac tion and to provide a uniform leverage, a uni-- form extent of dip of the key-levers andv a uniform touch throughout the system.

A further object of the invention is to provide an eflicient roller bearing su port for the ty e-bars and the character 0 whichis' such t at a large number of type-bars can be mounted or supported upon the segment without increasing the size thereof. J

To the above and other ends which will hereinafter appear, my inventionconsists in the novel features of construction, arrange ments of parts and combinations of devices to be hereinafter described and particularly pointed out in the'appended claims.

In the accompanying. drawings, wherein like reference characters indicate corresponding parts mthe various views, Figure 1 is a front to'rear vertical sectional view of one -fornr-Joftypewrltingmaclnne embodying my invention.

I have illustratedmy invention applied to a front-strike typewriting. machine, or to one charact r of visible writing machines, though it s ould be understood that from certain aspects the invention may be applied toother styles of writing machines.

The frame of the machine comprises a base 1, corner-posts 2 and topplate 3, which latter supports a suitable traveling carriage (not shown) that carries a platen 4., diagrammatically illustrated in Figs. 1, '2 and 9. The carriage likewise supports a feed-rack 5, which meshes with-a pinion 6 carried upon the forward end of a [shaft which is supported in a bearing 7 mountedupon the to -plate of the machine. The rear end of t eshaft to which the pinion '6 is secured is operatively connected to an 'escapement wheel 8 with which feed-do s 9 006 crate. j The dogs are carried by a roc er 10 having a rock-shaft 11 supported in bearings in a bracket-plate 12. A for- Wardiyprojecting arm 13 extends from the rook-shaft and carries a. transverse bar 14, to the'ends of which are connected depending links 15. The-lower ends of these links are connected to a universal bar 16 that extends beneath. the various key-levers 17. The rock-shaftl-l and the parts connected thereto are restored to the normal position by a1spring18' connected atone end 19 to the bracket plate 12 andat its opposite end 20 to the rock-shaft. The key-levers 1 7 arepreferably made of wood and each key-- lever hasanopening therein near the r-ear end, in whichiis seated a metallic thimble or .bushing 21. This thimble has 'a flange 2 2 on one end thereof and may be inserted within the opening .in the key-lever and 2 of the drawings, thus-firmly clam onseeuring the thimble or bushing tot e which extends through the thim'bles' in the.

."entire series of key-levers and is secured at its ends to the base 1 of :the machine. A depending'guide comb 25 is secured, to

"'thebase ofthe machine near therear portion thereof and alike. depending comb 26 is secured to the base near the forward por-q tionthereof in order to guide the key-levers in their movements, it being understood that :the key-levers are received between the teeth of the combs or guides and 26} The forward ends of the key-levers are provided.

' with the usual finger-keys 27 and a yoke 28 is secured to each key-levernear the rear portion thereof by a rivet 29 orother suitfable-connecting means; The upwardly projecting. freeends of each yoke are united by a pin 30, that-extends between the arms and is. received within aslot 31 in a substantially horizontally dis osed straight sub-lever 32 .which' is pivote at 33 in a slotted bar 34 secured to the base of the machine and extending from side to side thereof. The

various sub-levers 32 are parallel and extend fore and aft of, the machine and are situated directly above the horizontally fdisposed key -l'evers 17 and. are substantially parallel therewith.- .The fsub-levers are preferably.

made of metal'and' the forward end of each sub-lever is. bifurcated or split at 35 '(see Fig. -;1 0) so as to provide two arms 36 be tweenwhich extends va pin 37 that constitutes the pivot of an anti-friction roller 38,

so that the'f anti friction roller is contained within a bifurcated portion of the sub-lever.

This anti-friction j roller is received within a slot 39 inthe-rearwardly extending arm 40 of a belly-crank 41 ivoted at 42in a slotted bar 43 that exten s from side-to .side of the machine' drawings, it will be observed that the bell-" From. an examination ofhigl'2 ofthe cranks are vertically disposed and are sub- I .stanti'ally parallel and are pivoted in a'single transverse'line andforward of the ivotal centers "of. the type-bars, and that t e upright arms 44 ofthe bell-cranks terminate at diflerent heights so that the up er ends thereof are segmentally arranged; t 1e short-,

est arm's being at the center of the system and progressively increasing in height as they approach the sides.

, Referring to Fig. 3, it will beseen that the, rearwardly extending arms 40 of 'the bellcranks are of progressively greater'lengths from the center to the sides of the system of bell-cranks and that the ends of said arms are likewise arranged segmentally. It will likewise'be seen that the sub-levers 32 vary in length and that the forward ends thereof are segmentally arranged t3 correspond to the segmentalarrangement of the rear ends of the bell-cranks with which they engage, so that thesub-levers are pro essively shorter from the center tothe si es'ofthe that the arms of the bell-cranks at the center of the system are shortest, whereas those at the sides of the system are the longest and that as the upwardly extending arms increase in height for operative connection to the type-bars, the rearwardly extending arms increase in length to a proportionate degree and that the sub-levers decrease in crease in length. The purpose of this con struction and arrangement is to afford a uniform levera e, and a uniform touch and extent of dip of the key-levers throughout the key-board of the machine.

I As will be seen at Fig. 2, the upright arms of the bell-cranks at and near the center of the system are substantially straightlthrough- ,out their lengths, whereas the u right arms of the bell-cranks at the sides 0 the system are bent inwardly in order to compensate for the difierence in width. between the system of key-levers and the segmentally-arranged system oftype-bars and so that theupper ends of the arms 44 of the. various bell-cranks may be situated in a segmental arrangement which conforms substantially to the segmental arrangement of the type-bars. The upper ends ofthe arms 44 of the bell-cranks are each connected to" a draw-link 45 that preferably consists of atwo-part link, the partsfbeing united by a turn-buckle 46 in order that the length of each link may be varied at will. The rear end of each of the links 45 is pivotally connected at 47 to an ear or projection 48 ona type-bar49, so that v adirect fore and aft pull is exerted by each bell-crank on its type-bar. Each type-bar is shown provided with two types 50 and with an eye or hub 51 that has an anti-friction roller-bearing ring 52 secured therein. This ring may be driven in placein the eye and held there by frictional contact or by any suitable means. The inner face of the' ring 52 is substantially V-shaped to provide a way or groove 53 for the anti friction balls or rollers 5 L A plurality of type-bars are mounted on each type-banhangcr 55 which comprises a bifurcated supporting portion 56 that-is adaptedto straddle the lowe edge of the type-bar-segment 57, the various hangers being spaced apart by lugs 58 on the segment. Extending transversely through each hanger are openings 59 and 60, the former of hich is screw-threaded for cooperation with e threaded end of a screw 61 that passes through said openings and through an unthreaded opening62 in the segment. The unthreaded o ening in each hanger has a counter-sun portion 63 for the reception system; From, this it will be understood length as the arms of the bell-cranks de" of the head 6ft of an associated screw 61..

By this arrangement each hanger is jr'igidly' secured tojthe typ'e bar segment and may be readily mounted eng rremovedtherefrom,

the heads .of the, various screws 6-lfbeing readily accessible for this purpose, as will be seen bylanexaminationmof' Fig. 2. 'Pr'ojecty. ing from the hangemis'a-central webI which has on the opposite'faces' thereof circul-ar. rollerebearings 66 for cooperation 1 with the a11ti friction balls or rollers I 4. The planes of the opposite faces of the web or of the bearings thereon are'inclined to the med-ian plane aof the Web, andof-the type-barhangerv so that theplane of one bearing 66 is at an angle to the plane ofthe other. I Extending laterally from'o'ppos'ite sides of the web 65 of-each' hanger and'at'right angles, to theplanes of said sides, are oppositely disposed s'crewthread'ed' pintles or studs or projections. 67, 'which' extend through the eyes of the. associated SYP bflI'S and constitute suppo'rtsffor' bearings plates 68. Each plate 68' has a central screw-threaded aperture by means of which" it maybe mounted and adjusted on-its pintle 67,- the adjustment being in vva plane parallel to .the.

plane of ,the associated roller-bearing 66..

Each bearing p1a'te68 has'an inclinedface i 69 that is received witlnnthe eyt of a type-- ing forcoeperation with .the anti-frictlon,

barand constitutes an adjustable roller bean rollers 54. \Eachlplate 68 has one or more threaded openings extending therethrough, (three being shown) for. the reception; of

" screws 70 which are adapted toproject through the plate and through the eye of the associated type-bar and to bear at their inner ends against a side orface of the Web 65 of. the hanger, as illustrated in Fig. 4, so

as to secure ,thelbearing'plate in the position to which ithas been adjusted andto prevent an accidental rotation -o'r rotary displace-v inent of the bearing plate- 'on' its pintle 67.

. By this construction the types-bars on each hangerare arranged side by side and the pivotal centers-of the various bars are in a 'singlecurved line. g v

' From'an inspection of Fig.'6, it will be seen thattheouter edge orperiphery of each bearing plate or disk forms a circular flange 71 that extends into a circular groove 72 in the hub or eye-portion or the b'earing'ring of the type-bar so as to" overlap the opening in the eye and the joint be'tweenthe bearingplate and type-bar an form a breakjoint, inv ordertopre'vent dust or grit from entering the bearings for the type-bar.

The construction is preferably such that the edge 71 of each plate will be maintained out of contact with the type-bar under the 'various adjustments of the plate in order not' to in-.

. terfere with thefree movement'ofthe typebar on its bearing rollers.

It will be understood from the foregoing description that. the cons'truction provides ity of type-bars.

the base of the machine.

.efiicient means for readily mounting or dis-- mounting 'thetype-bars; that it provides eflicient roller-bearings that tend to prevent a lateral deflection or movement of the bars at their; bearings and during the movements of the bars to and from the printing-point and thatfla large number of bars can be mounted n the segment without ncreasing the'siz'e' thereof and that each hanger supports oninterposed bearing rollers, a plural- It will likewise be seen that the construction is such that the median "plane of each type-bar and its bearings radiates from the printing point, or a point adjacent thereto and that this median plane bar, so that it is unnecessary to bend the various type-bars at the sides of the system.

The type-bar segment 57 is connected-by screws 57 a to a vertically movable frame 73 which has depending arms 74 at the ends thereof. Links 75 are each pivoted at one end 75 to the upper portion ofthe frame 73 and at its other end to a bracket 75 secured to the frame of the machine. The lower ends of the arms 74 are pivoted to parallel arms 76 that'project from a rock-shaft 76v that .extends from side to side of the machine .and is supported in bearings 77 secured to extended rearwardly at 78 soas to form shiftmg lever-arms for effecting a vertlcal mo e- The links 76 are 9 ment .of the type-bar segment and type-bars for upper and lower case writing, and the parts 75 and 7 6 constitute in ffect parallel links .on which the segment moves. The lever-arms 78are connected-to links 79 and .to suitable key-actu ating devices (not shown) and by means of which motion maybe transmitted to the shifting levers 78. One set of iparallel links 75 and 7 6 and a shifting lever, 78 aresituated at each side of the machine for connection with the type-bar-segment so that the segment may be elevated or lowered at both sides thereof when the segment is shifted. Securedto the rear 'ofthe segment is a depending arm 80 to which is connected by screws 80 a forwardly and upwardly extending arm 81 which has secured thereto at 82 a segm'ental pad 83 for supporting the free ends of the type-bars. l orwardly projecting arms 84 extend from the segment, one

Each snh-lovor has one end of a contractile spring H7 oonnoctod thereto, whereas the op posito ond of said spring is connected to a fastening dovico 88 thatconsists of a stapleliko piece, one arm 88" of which projects through an oponing in the associated key-lever and is threaded at its lower end where it oxtends beyond the key-lever for ctiopcration with a nut 80. This so-callod nut may consist of a block of leather aportured to receive the scrcwthreaded end of the fastening device. The shorter arm 88* of the fastening device extends into an opening 9t) in the key lever and affords a vertical adjustment of the fastening device or'an adjustment thereof relatively to and transversely of the key lever so that the tension of the spring may be varied and the short arm of the fastening device may, if desired, be removed from the opening 90 in-the key-lever to permit a disconnection of the spring from said fastening device. \Nhen, however, the short arm of the fastening device is seated in the opening 90 in the key-lever, as illustrated in Fig. 1, the spring cannot be disconnected from said fastening device, though an adjustment of the tension of the spring thereof may be effected. This spring '87 is e'liective to restore the key-lever, sub-lever, bell-crank and type-bar to their normal positions. From a comparison of Figs. 1 and 9, it will be observed that the spring is under its lightest tension when the parts are in the normal positions represented in Fig. and when a key-lover is depressed, the forward arm-of the.

sub-lever 32 and the key-lever 1.7 will move in opposite directions, thereby expanding When the tinger-key is released, the contractile spring 87 will draw the forward arm of the sub-lever and the keylevor 17 towards each other, thereby restoring the various parts to their normal-positions, as illustrated in Fig. 1. The connec tion of the restoring spring to the sub-lever and koy-lcvor in the manner described, aflords an easy initial movement of the keylcver and the parts controlled thoreby and causes a quick restoration of the parts from the printing position by reason of the factthat the ends oi the spring are moved away from each other by the parts to which they are connected and. the spring is under its greatest strain when the type-bar is in its printing position.

\ivhile I have shown and. described the;

embodiment oi my invention in one form of typewriting machine, it shouldbe understood that various changes in construction may be made without departing from the spirit of my invention and that certain l'oatnros thorool may be employed without the othors.
