IMPROVEMENT IN STEAM ROAD-WAGONS.

Specification forming part of Letters Patent No. 222,352, dated December 9, 1879 application filed 5 October 10, 1879.

1 To all whom it may concern:

I Newport, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Steam Road-Wagons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification, in which Figure 1 is a side view of the road-Wagon Fig. 2, a plan view; Fig. 3, a bottom view I with a portion cut away.

In the accompanying drawings, the letter A indicates the cylindrical casing of a returnflue boiler, the fire-box B being under the smoke-flue O, and in front of the fire-box there is a platform, D, for the engineer. The waterbox E is under the boiler, and the coal-box F is in front of both the boiler and the waterbox. I

The steering apparatus is at the forward end of the wagon, and consists of a worm, G, journaled in brackets H, and provided with cranks I, and meshes with a wheel, J, the teeth of which are cut 'so as to conform to the pitch of the Worm. I

The worm-wheel is on top of a shaft, K, which has. a pinion, L, at its lower end, that gears with the teeth on the inside curve of a segmental bar, M, that is bolted to the arms N, extending forward from the front axle, O, of the wagon, said axle being pivoted to the bar P, which extends from front to rear of forward part of the wagon, as shown in Fig. 1.

The letter A indicates the drive-wheels of the wagon, interiorly cogged, as shown, and a pinion, B, gears therewith. The pinion B is on a shaft, 0, journaled in blocks D, which are bolted or otherwise secured to the under side of the longitudinal bars E F. To the other end of said shaft there is keyed or otherwise secured a gear-wheel, G, which engages with a spur-wheel, H, on the end of a shaft, I, which is journaled in blocks J, bolted to the bars E F, and on the said shaft, between the two bars E F, there is a band-wheel, K, to which motion is imparted by means of a band, belt, or chain connecting with another wheel rotated through the instrumentalitiesof levers and gearing, the construction, arrangement, and operation of which it is here unnecessary to describe, inasmuch as they are all well known to persons skilled in the art of constructing engines. Y

The shaft 0 is so located with reference to the drive-wheel A that the pinion B will gear with the cogs thereof at a point in front of and on the same plane with the axle of the drive-wheel, and this location of the said pinion with relation to the said drive-wheel and its axle is one point of my invention, for by so locating it I get the power applied on a horizontal plane with the center of the drive 'wheel and relieve the axle of considerable pressure 5 and practical application has demonstrated that the power is applied. with more effect at that point than at any other.

The brake for this wagon consists of two levers, L L connected to each other by means of two vertical rods, M. The lower lever, L,

has two arms, N N the arm N being the rod extending from side to side of the wagon.

One of the vertical rods M is hooked or 7 otherwise secured to the short arm of the lever L, the other end thereof being similarly connected to the arm of the lever L above it, while the other vertical rod is connected to the end of the other arm of the upper lever and to the long arm of the lower lever some Way back from its end. I

A coiled or other spring, Q, placed'around one or both of the vertical rods M, and bearing against the arm of the upper lever and a plate, Q below it, forces the top lever up from off the band-wheel when the brake is to be released.

The top lever, L, consists of two arms, R,

and connecting-rod R the arms being curved, as shown, and provided with shoes S, tobear on the band-wheels K when thebrake' is applied, and the rod R extends from side to side of the wagon, resting on the frame wheel K and spur-wheel H, gear-wheel G and pinion B, and drive-wheel A, the pinion B being located in front of and on the same plane with the axle of the drive-wheel, all as described.

In testimony that I claim the foregoing I have hereunto set my hand this 4th day of October, 1879.

OR-RIN O. HARRIS.
