SPECIFICATION forming part of Letters Patent N o. 329,238, dated October 27,1885-v Be it known that LLOYAL C. TABER, o Danforth, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Traction-Engines, of which the following, taken in connection with and exact description.

.This invention relates to the tion-engines which have the 'class of tracpropelling-power wheels as well as to the hind wheels, and has particular reference to the engine for.which I have obtained Letters Patent No. 294,930, dated March 11, 1884.

' In the manufacture and use of said engine In-the accompanying drawings, Figure I is an elevation of my improved tractionengine,. taken at the side which carries the train of gears by which` power is transmitted to the four carrying-wheelsthe engine proper and its connection with the driving-shalt being omitted, as such are immaterial to the illustra-v tion and description of the invention. Fig. II

of the traction-engine to which my improvements are applied, said figure being partly a sectional view taken'on -line x in Fig. III; and Fig. III is a front end view.

Similar letters' of reference indicate corre-- sponding parts. Q

A represents the boiler, which is formed at Said boiler is'supported on the Iaxles a a at opposite ends,va'nd" engine, and of the greater. portion of the gears falls onto 4the central portion of lthe boiler, the rigidity of which has heretofore been depended upon for Yresisting the weight and transmitting it4 to the axles. Experience has proved that the aforesaid weight produces such a strain on the seams of the boiler, especially at the junction of thel forward portion ofthe fire-box with the boiler, as to weaken or open the seam `thereat. To obviate this defect I extend from the bottom of the ire-boxfAto the upperpart of 'the'post K, by which the .forward end of the boiler is supported on the serial No. 114,852. (No model.)

axle, a brace, B, which is secured at-its rear end to a knee, f, embracing the bottom cornerofthe forward portion ofthe re-box,andiirmly bolted thereon, said knee being provided with forward-projecting ears "n 'n' anda', betweentwo'of which the end of the brace ente-rs, andl 'i is secured thereto by a bolt, o, passing through f said ears and end of the brace. The lforward end -of the brace is inserted between'lugs ory ears p, formed on the rear of the bearing-post` K, to which lugs or ears the brace is connected .The traction-wheels W W receive propel-4 ling-power from the driving-shaft C by. means ofa train of gears, F F F F, and a spur-wheel, E, mounted on gudgeons which are secured to the side of the'boiuler, aS represented in Fig. .I l

of the drawings. apinion, D', fastened on the driving-shaft, and engages also a gear-wheel, O, which in conjunction with other gears, hereinafter-described, transmits motion to the forward axle, a. is provided on top with a socket or concave step, b, of the form of a section of asphere,. and in this socket is seated the bearir'ig-post K, which is rmly bolted to the under side of the boiler, and has its lower end of sem'ispherical shape, corresponding tothe socket' Said spur-wheel E meshes in On this axle I fit looselya sleeve, awhich'i b, in which it is stepped. The' boiler is thus mounted on the forward axle by a ball-andsocket joint, which allows the said'axle to'oscillatei-n all directions.

In. order to connethe bearing-post K in the socket b without interfering with the aforesaid universal movement ofthe. axle, I providethe- 'under side of thejaxle'with'atdownwardapro j ecting studpin, u, to which I connect the forward end of the reach r, which 'extends across the under side ofthesl'eeve, and has an eye.

for the reception of said stud-pin. vSaid end of the reach projects forward 4from the sleeve I s, and isprovidedwith another eye for the re-A ception of the, lowervend of a coupling bolt or link, d, which has its upper end pivoted on the front`of the post K, at a poi-nt in a line extending horizontally through thc` center of -the sphere formed onsaid post. Thelower end ofthe linkd passes through the 'end of the reach @and is provided on .the under side roo` c, and on the steering-chains,

thereof with nuts, which hold the reach up against the sleeve s and complete the coupling of the ball-and-socket joint between the boiler and axle. The pivotal connection of the link ou the postK allows the axle tofreely oscillate in a verticalA plane, as indicated by dotted lines in Fig. III of the drawings. The rear end of the reach is inserted between the two ears u n of the kneej', and is connected therewith by the bolt o, passing through it, said knee consisting of a single plain casting, which has a firm bearing on the shell of the water; jacket surrounding the fire-box, and serves as a convenient and secure fastening for the brace B and reach r. Said brace and reach thus have in common one attachment at their rear ends, and this is a very -important feature of my invention, inasmuch as the reach has to of the forward axle being. crowded rearward resist the tendency by the encounter of its traction wheels with obstructions on the road, and also the tendency of the axle being` crowded forward by the strain transmitted to the axle bythe engagement oi' the pinion P with the gear R, and these strains are transmitted by the reach to the knee f, where they are resisted by vthe brace B, which latter transmits 'the strain to the rigid post K on the forward end of the boiler, and thus completely relieves the rear portion oftheboiler of said strain.' The post K is hollow, and has on one side an opening, opposite side al rigid horizontal sleeve, Il, projecting therefrom. Diametricall y through the semi-spherical portion of' the post K is extendeda counter-shaft, L, one end of which is journaled in the sleeve h, and the oppositev end projects through the openiug'c, an'd is journaled in a box, c, attached to avertical rib rising from the sleeve s. This countershaft is provided with counter-shaft to foliow the axle a in its oscillatory movements, while the opposite end of parallel with the driving-shaft C by means of the sleeve h. This lineally-confined end of the counter-shaft has attached to it aA pinion, N, which meshes in a pinion, N', mounted cna gudgeon rigidly attached to the boiler, and on the side of the pinion N' is the gear-wheel O, which receives motion from the driving-shaft C, as hereinbefore described.

On the vibratcry7 end is a pinion, P, which meshes in a compensating gear, R, monntedon the axlea, said compensating gear being adapted tc transmit inotion to the axle at varying speed when turning the axle to guide the engine around curves of the road. l

The engine isguided by means of the usual IL la, which are connected to the ends of the sleeve s, and' are wound in opposite directions on a shaft, t, which is under the control of the operator, by a hand.-'

wheel on the end,l ofva shaft carrying a worm of the counter-shaft L `IK; and to obviate'such injurious effects I employ check-chains Z, which are at one end `hung loosely on the shaft t,so as to prevent wound on the shaft, and'thus have attachment stationary and indetheir being their rear .pendent of the steering-chains. The opposite ends of the check-chainsare securely coupled to the steering-chains at any suitable point between the shaft t and the axle -sleeve s. Said check-chains areof such lengthtthat in the operation of turning the axle laterally the check-chain which is coupled to the unwinding or payingout steering chain is drawn taut andcaused to arrest the Inovement cf said steering-chain. v
