Tool! whom it may concern:

Be it known that I, EDGAR H. BERRY, a citizen of. the United States, and resident of. theborough of Brooldynflt it' of New York, in the county of Kings an State of; New York, have invented certain new and uscful Irn rovements in TypeWriting Machines, of which the followin is a specification.

My invention re ates to, typewriting 'machines and more particularly. to linc Spacing mechanism and has for its object to provide ifimgroved mechanism of thecharaoter speci- To theabove and 'otherends whichwill hereinafter ap ear, my invention consists of the feat es '0 construction, arrangement of arts an combinations of devices set forth in the following specification and particularlj pointed out'in the appended claims;

Fig. 2 is a fragmentary plan view of the same. Figs. 3, 4 and are detail views of parts of the structure.- F ig..6 is an enlarged detail sectional view taken through the right-hand end bar of the 1platen frame and showing'thc actuating cran arm and the screw stop with which it cooperates. Fig. 7 is a detail edge view partly in section, of the actuating hcll' cran and hearing sleeve to which it is con nectcd. Figs. 8 and 9 are detail sidc and end views rcspcctivcly of the hcarin; for the rock shaft. I

carriage comprises front and rear cross bars 10 and 11 respcctively in which grooved tracks are formed for cooperation with the anti-friction balls 7. lhese front and rear cross bars are connected by end bars 12 so as to form a rectangular carriage or truck' Each of the end bars of the carriage hasa dcpending arm 13 and'an u nvardly'ext'endihg a'rni 14 to which parallel links 15 and 16 re speetivel are pivoted, said links being pivoted at t eir rear ends to end plates 17 of tho platen frame, as indicated at. 18 to afford an n and down case shift movement of the p aten frame. Bearings are forined'dn the end plates of the platen frame for a platen shaft 19 whichsupports a cylindrical platen 20, said platen carrying a-line space r atc c't roller dctent 32 is earricd by aspring arm "23 fixed'at 24 to the platen frame, said roller dctent cooperating withtlie tecthof the. line space ratchet whccl 21.

The right-hand end bar 1'2 of the carriage is slotted or rccessed in the top thereof as indicated tit-25 for the reception of a central depending wch, lug: or progection" .26 on a recess 25 corresponds with the thickness of the llhl or lirojcction 26 so that the latter will lit snugly within the opening and he prcvented from moving or turning laterally. lhc hottoni far-n28 ol' the hcaring block rests upon tho upper face or side of the end liar 12 so that a [Will scat is 'providd therefor.

(-oilml rcstol'ing spring 31 is con taincil within the opening and surrounds the rock shaft and is connected thereto at one cnd, the opposite end of said spring being con'ncctod to the hearing block 27 An enl$tl',{(ll cylindrical hearing portion 33 is l'orincil on the rock shaft for cooperation with the h'caring opening 30 forward of the spring wheel 21 at the right-hand end thereof. A

hearing: hloclr Z7. The width of the slot or end an angle arm or finger of the bell crank is pivoted, by a s ouldered mounte 55 has an opening 57 for cooperation with a 31, a circumferential shoulder 34 on said f shaft abutting the end of the bearing block 27- to revent a rearward movement of the rock shaft in the hearing. The rear end of the rock shaft has an enlarged cylindrical portion 35 which bears in the reduced rear end of the opening 30 in the bearing block 27 and a projection 36 extends rearwardly from the rock shaft beyond the bearing and is flattened on two sides thereof to correspond to an opening 37 (Fig. 4) formed in a crank arm 38. Said crank arm is secured against dis lacement from the end of the rock shaft by a headed screw 39, the stem of which takes within a threaded opening in the end of the rock shaft. The crank arm 38 has an openin 40 (Fig. 4) for the reception of abent en portion 41 of a connecting link 42. The lower end of this connecting link is bent at 43 like its upper end, but at right angles thereto, for engagement in an o ening 1n the rearwardly extendin arm 44 oi a hell crank lever 45. The be crank lever has an upwardly extending arm 4fi bent at 47 so as to carrythe u per end of the arm 46 out of the plane of the'lower arm and in substantially the plane of the line s acin ratchet wheel as shown in Fig. 2. T e be crank lever is fixed to a bearin sleeve 48 (Fig. 7) which turns on a shop dered and headed screw 49- taking at its threaded end within a tap (1 opening in a depending lug on thewighth and end bar of the carriage, so as to form apivotal bearing for the bell crank in order that the latter ma move substantially in a vertical plane w 'ch extends fore and aft of 'thggnaclune; The upri ht arm 46 screw 50, to a rearwardly extending link 51 that moves fore and aft of the machine and is pivotally connected at its rear end as indicated at 52 to a line spacing pawl 53. This pawl is ivoted' at 54 to a carrier 55 which is d to turn around the axis of the pllaten and to vibrate fore and aft of the mac une. n a

Figsjlitand 2 show the parts in their operated positions, that is, in their positions at the end of a line spacing movement, and from an inspection of Fig. 2 it will be seen that the line spacing awl moves in the plane of the line spacing wlieel and fore and aft of the machine and that the rearend 56 of said pawl at the termination of the line spacing movement is over and adjacent to the detent roller 22 so asito lock the detent against out ward movement from between the teeth of the line spacing ratchet wheel, thus preventing an overthrow of the platen. The carrier pin 58 carried by the line spacing pawl, the o eni bein sufficiently large to afford a slight Timitef independent movement between the pawl and carrier. The extent of line spacing meva neet sa es-ted at each actuation of the finger piece 32 be determined by an adjustment of the carrier 55, the initial position of said carrier determin ing the extent of such movement. The means for eflecting such adjustment may be the same as those shown intheapplication of Oscar Woodward hereinbefore referred to, and I have not deemed it necessary to illustrate said means as it is unnecessary to an understanding of my present invention.

From the foregoing description it will be understood that an actuation of the finger piece 32 is effective to move the carriage to the right and is likewise effective by the same operation to actuate the line spacing mechanism. The operation of the finger piece 32 turns the rock shaft in its bearing 27, thus moving the crank arm at the rear end thereof downwardly from the full to the dotted line osition shou n in Fig. 6 u here it is arrested engaging an adjustable screw sto 59 received in a tapped opening in the rig t-hand end bar,l 2 o the carriage. The arrest of the crank karm by the stop 59 likewise effects an arrest of all the arts controlled thereby. Motion transmitted from the rock shaft to the crank arm is imparted downwardly to the upright link 42 and from the link 42 to the be] crank lever 45, thence rearwardly through the link 51 direc'tl to the line spacing pawl. The first part 0 the movement imparted to the awl is to turn it on its iuot 54 independent y of the carrier 55 in on or to effect an engagement between said pawl and the line spacing a heel. A further movement of the pawl is effective to move it and-its carrier together with theline spacing wheel and platen in order to effect a line spacing movement of the latter.

In the present construction I have provided a link connection between the crank arm 38 and the bell crank lever45 instead of a sliding and turnin connection as in the construction of the 'oodward application hereinbefore referred to. Moreover the bearing piece 27 is formed separatel' from the carria e instead of being integra therewith as in the said Vl oodward construction.

From an inspection of Figs. 2 and 5 it will be seen that the pivotal portions of the link 42 which fire received in the openings of the crank arm 38 and the arm 44 of the bell crank lover extend at right angles to each other and that motion may be efficiently transmitted from the crank firm to the bell crank lever notwithstanding the fact that these parts move in' planes at right angles to each other.
