"'dit 'terior .thereo. f with a knurled vide A for su portin the type-bars, ribbon mechanism, c., an operated by letter-spacing mechanism. (Outlined in dotted lines 1n Fig. 2 and in full lines in Figs. 2" and 2.) This carriage I will hereinafter refer to as the writing mechanism. For supporting this laterally-traveling carriage or writingmecha'nism A, I arrange guide-rails c, whichextend between and are sustained by two standards C and on which travel rollers c, Figs. 1 and 2, mounted on the carriage A. The standards C and the connecting-tracks c constitute a second carriage A, which is arranged to travel on the tracks B. It is to be understood, therefore, that I have in this cot struc-' tiontwo carriages, one, constitutingthe writmechanism, A", which travels on the rails c aterally over the platen for letter-spec" and the other, A, traveling on the rail s i longitudinally over the laten for line-spacing. The present case, owever, relates to the second carriage A and feed mechanism for effecting its travel, and general mention herein of carriage and feed mechanism is to be' understood to refer to the same rather than to the laterally-traveling carriage and its feed mechanism.

A plurality of antifriction-rollers c are pivotally su ported on each standard near its lower en and are preferably provided with a recessed periphery for engaging the track portion 1) of the track-rails. antifriction-rollers c are carried b each standard in position to engage the un er surface ofa flan e b on the track-rails to pife .vent tilti o the carriage relatively to its rails. A s aft D is rotatably supported on arranged within a casing C, carried by the ad'- jacent standard. A'tube d (shown'surround-l mg the shaft B) may be secured at its respective ends to the casing C for increasing the of the structure.

each casing C a gear-wheel E and ratchet-wheel I are rigidly secured to shaft D, and a ear-wheelGis loosel mounted on said sha t, and '0. sp', ls ring has its respe 'tive ends connect to t e ear-wheels E an G. The gear-wheel G is s own with its teeth engaging the pinsl h of a lant pinion these teeth being so fonnedt at the ear-wheel G and pinion H cohstitute a selfcoking mechanism. The pinion is secured to a. spindle h, wh ch extends; through the standard. (3' and is 'roaiilidgt i er- .1 ii. means of which the pinion H can be 0 stated torotate the gear-wheel G'for vary tension of the spring F.

A plate J is sl dab'y supported between .1. 9 gear-wheel E and ratchet wheel of screws 3'', which extend throng otsfj in, said plate into studs The date is re;

orbri gi dgthe sha D with a recessy" 7 its normal POSlliiOD'. The arm is rovided and carries a ri id dog 7'. A spring j", connected to the p ate J and to a pin carried by the standard, tends to retain said plate in its normal position with the rigid do i out .of engagement with the ratchet-wheel A plate M, carrying a loose do mounted upon the plate J and provi ed with a yoke portion m, bearing on the shaft D. A pin 3' on the plate J extends through a slot m in the plate M and limits the downward swing of said plate M relative to the plate J. The slot m is formed with an singularly-ex tending upper portion m, which permits the plate'M to be moved independently of the plate J for removing the loose dog m from enia ement with the ratchet I.

j, is provide with and'carries a rod a;

In the coiistruction shown the rod n exteeds between the levers N on the two standards C.

A shaft p, journaled in the type-writer bashot and preferably extendin at the rear thereof, carries a tripper-arm arranged to engage the rod n. A'longitudinal general release-key P is shown secured on the righthand end of the shaft 29 in position to he'con .Y'eniently gras ed simultaneousiy' with the handle cand t e general release-l ever I, ar ranged in proximity thereto aiidlwhich enages the transverse escapen ent'meclianism l" on the laterall traveling or writ' mechanism carriage ii,- the details of w 'ch are more fully set forth and claimed in my pending application filed April 26, 1902, Serial No. 104,842. It will be understood therefore, that by arrangin' the keys P and P in proximity to the handle c the operator can grasp said handle a and with one finger operate said lever P and with another finger operate the transverse esca ement general releasalever P, and by then aving both the carriage A and the carriage A free to travel positio carriage A laterally and the carri'age'A lon gitudinally o'ver the platen) at any desired point can easily and quickly be effected, and this necessitates only the use of the opera tors one-hand.

When the projection 1' is in the 'r'niddle opening, the arm Q will be so adjustedi'tjhst the step q will constitute a stop for 'Z iiiii'itingthe upward swing of said plate M, and when the proieetion r is in the top 0 ening of the series the arm Q will be raise out of the path of the plate M during the upward swin oi the letter; If desired, the spindle g, which carries the arm Q,rcould halivotally supported on the rigid dog-plate and in such construction it will be necessary, to provide slots in the casing U for the spindie and projeetionrfl The adjusting-arm Q ghus constitutes anadjustable stop for limiting the swing of the loose dog-plate M to produce single spacing, double-spacing, or any lar er spac desired.

he operation of the feed mechanism is as follows: The spring F having been placed under roper tension by means of the pinion 'H ten s to rotate the ear-wheelE, which meshes with the rack on the track-rail. The gearrwhoel E is' norrnally held from rotaengagemeiit oi the loose dog m with the witerhasket-that is, the carriage or writing *niechanism A-back along the transerse s 'tp position said carriage A? at its startingpoint at the left of the center of the platen for starting a line the cam-plate L will engage thewlsg k? on the arm K and swing shiiting the plates and M to the left (see Fig. 3) suiiic ently to throw the rigid dog en s e essssh' the ratchet-whee I md t6fi bljlf loose, do m from engage- ;ment with said wheel. X en the parts are brought to this position, the wheel will have the'very slight rotation necessarto bring its adjacent tooth a; ainst' the rigi dog 7', and

is; until sto ped b its contact d gusting-arm whio lat r n be i le, double, gr larger 7 "a I l i 7 a pg l as lil the am late L from the lugkf'th r :piring 9'' will act to rot-om the plates hi their normal position, thereby tion under the action of the spring F by the ratchet-wheei I. Upon shifting the type vpivotal support, thereby the spindle g, is provided with a handle 1' and throwing the loose. awl m into engagement with the ratchet-w eel I and releasing the rigid pawl j therefrom. T1163 ring I will then act to rotate the gear-w eel E and ratchet-wheel I to pro uce travel of the standards along the trae -rails B until the loose dog m" has been carried to'its lowest normal positionbythe rotationoftheratchetwheel I, when the Wheels E and Iv will be locked against further movement.

To effect general release of the feed mechanism, the key P is actuated .tpcause shiftin 1 ofthe rod n. by'the tri per-arm O. Sue shifting of. the rod 'n, Wil swing the levers N about their pivotal supports j and draw the loose do -plates M to the left (see Fi 3) sufiicienfiy to release 1116 loose do s m rom engagement with the ratchet-whee s I. ,During such movement of the plates M: the pins 7'", carried 'by the plate J, willtraverse the 'angnlarlysextending upper portion m} of the slot m in the late M, and thereby permit the movement 0 the plate :M without any motion of the plate J. It will thus be seen that upon actuation of the key P both the rigid dog 7' and loose dog m9 will beheld out ofengagement with the ratchet-wheel I and the eed mechanism thereby released for free movement. along the track-rails.

It is to be understood that initially the carriage A is positioned at a articular-point by first operatin the genera releaseslever P and moving sai carriage tothe line where' the type-writer is to print. When the writing-mechanism carriage A has traveled across the platen and completed a line or such portion thereof as may be desired, said carriage A is shifted back to its starting- 7 point and there the cam-plate which it carries, as already stated, enga es the lug k on the arm K, which operates t e feed mechan ism of the carriage A and, under the-action of the propelling-spring F, said carriage A is moved to the position of the next line. In this manner, as will readily be understood, I secure an automatic operation of the feeding of said carriage A by the particular positioning of the carriage A. I however, it is desired to secure operation of said feed mechanism for line-spacing otherwise than in the automatic manner described and also w thout. operating the general release-lever-R, the operator moves said arm K by hand bydraivin forward on the knob k on saidarm K, whic o erates saidarm and its connecting parts in I -t e same manner as when. itwas'actuated automatically, as aforementioned.

Such finger would preferably be adjustably held in order that it. can be thrown out of operative position when desired.

Figs. 13 and 14 illustrate a modified construction for varying the tension of the sprin s F. In this modification the gear-' whee G and pinion .H are discarded and a pinion S is arran ed in mesh with the gearwheel E. A; spindle s has secured thereto the pinion S and a knurledhead s, which latter is 1provided with teeth 8 which are springhe din enga ement with teeth sf, carried. by the standar C. A spring 8 .bearin between ahead 8. on the spindle s and a den e s" on the knurled head 8 acts to hnldt e teeth 8 and s" in engagement.

From the above construction it will be un- 1 o derstood that the knurled head 8 can be pulledout to disengage the teeth 3 and a? and then turned to cause rotation of thepinion S and gear-Wheel E for varying the tension of the spring F. Whenthe sprin F has been roperly adjusted, the knurled head 8? is reeased and pressed inward by the spring 8 to bring its teeth 8 into locking en ement with the teeth 8 on the standard (ill iereby preventing unwinding of the spring F.
