ROADI-LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 256,120, dated April 11, 1882,

Application filed March 6, 1882. (No model.)

T all whom it may concern Be it known that I, RYoN P. BRYSON, a citizen of the United States, residing at Burnt Chimney, in the county of Rutherford and State of North Carolina, have invented certain new and useful Improvements in Road-Locomotives, of which the following is a specification, reference being had therein to the accompanying drawings.

:0 My invention relates to improvements in road-locomotives; and the object is to construct road-locomotives in such manner that they can be readily and easily guided in any direction desired, and that the driving-power 1 is applied to the wheel, so that there is noloss of power, and the locomotive will run steady on common roads or streets.

The invention consists in the construction and arrangement of parts, as will be more fully described hereinafter, reference being had to the accompanying drawings and the letters of reference marked thereon.

Like letters refer to like parts in the different figures.

In the accompanying drawings, Figure 1 represents a side elevation of my improved road-locomotive with one of the rear wheels removed. Fig. 2 is a plan view of the same with the boiler broken away, and continued in 0 broken lines over the driving machinery.

In the drawings, A is the boiler of a roadlocomotive of ordinary construction, having the usual smoke-stack, B, steam-dome D, and throttle-valve O. A pipe, a, connects the throt- 3 5 tle-valve, which is arranged in a close chest,

a, secured to the boiler and with the steamdome, andanother pipe, at, on each side of the boiler, extends to the steam-chests b of the two cylinders 0, secured by a hollow bracket or saddle to the bottom of the boiler. The steam is exhausted through the hollow saddle into the smoke-stack. The usual guides, d, are also secured to the bottom of the boiler, and the connecting-rods e are attached to the cranks f g on a crank-shaft, E. This shaft is journaled in brackets h, secured to the sides of the boiler, and on the outer ends of said shaft are arranged the pinions 4 which mesh into gear-wheels k, secured to the hubs of the rear driving-wheels, G, revolving on the end of the axle F. This axle F is supported in brackets Z, extending from one side to the other, and the outer ends form the journals for the wheels G. An ordinary cab, H, is placed over the end of the locomotive for the engineer. The forward end of the boiler is supported on a guide or pilot wheel, I, the shaft of which is attached to an upright shaft or pivot, m, which extends in the smoke-arch of the boiler, and to its upper end is secured an arm, n, which extends through the. side of the boiler and has connected to its outer end the rod 0. This rod extends toward the rear of the locomotive, and is connected to a lever, K, having an ordinary spring-catch, p, which engages with the notches in the quadrant L. As the lever is moved backward or forward the guide-wheel is moved at a greater or less angle, and the locomotive is thus guided in one or the other direction. To prevent any undue friction the front end of the machine is supported on the fifth-wheel or saddle M, the lower part, q, of which is forked to admit the guide-wheel between it, and the pivot on is secured to the uppersidethereof. ThepartMisrecessed around its upper edge, and fits into a ring or seat, 1", that is secured to the boiler and projects partly up into it. The guide-wheel is journaled in boxes which slide up and down in grooves 8, arranged on the inside of the part q.

By arranging the chest for the throttle-valve in the manner set forth the steam has free access to each cylinder when the valve is open.

The driving-wheels G are provided with steel boxes, which are made adjustable; and I reserve to myself the right to make a separate application therefor at some future time.

The pinions are provided with a thu mb-sprin g and catch, which can be disengaged for throwing the gears out of contact with either one or both of the pinions, as desired, for turning very short curves, or, when both are thrown out of gear, so that both engines can be run rapidly in case the Water has become low in the boiler. The cams or eccentrics are also provided with spring-catches for the purpose of reversing the valves. A feed-pump, N, is arranged between the two engines,and is driven by an eccentric or cam on the crank-shaft.

The advantages of my improved locomotive will be readily appreciated by all engineers and others skilled in the art, and some of them are that the machine is very compact and simple, the parts are not liable to get out of order, it can be readily turned at very short angles or curves, it forms a very rapid locomotivc for travel over common roads and streets, and all of the machinery is placed above the axles and leaves the entire space below unobstrucled.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, 1s- I 1. In road-locomotives, the pilot-wheel supported on a saddle, M, recessed on its edge and fitting into a ring, 4', secured to the boiler, and operated by mechanism from the cab, substantially as set forth.

is attached, and connected to a rod, 0, operated by a lever, K, all substantially as specified.

3. The traction-engine herein described, consisting of the boiler A, supported upon the front pilot-wheel, I, and rear driving-Wheels, G, the cylinders 0, and engine-shaft having pinions 6 meshing with gears K on the drivewheels, said cylinders and engine-shaft being secured to the under side of the boiler, and all arranged as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

RYON P. BRYSON.
