thereby rotating said post more or less and setting said wheel in such a plane of rotation that when engaged with the switch-point 18 it will, as the car moves along, cause said point to be swung against or from said rail 17 as may be desired. The continued clownward movement of said lever 10 or 12 then brings the bifurcated end 20 of the moving one of said levers into engagement, indirectly, with one of the collars 23 on post 15, thereby causing said post to be moved downward to such a degree as willbring said wheel 16 lo enough for said engagement with the said switch-point. hen said operator on the platform releases said footpost, the spring 22 causes the post 15 to rise and the collars 23 thereon, engaging the ends of the springs 21, together with the connterweights 24, serve to bring both levers 10 and 12 and the post 15 again to operative positions, as in Figs. 1 and 2. The springs 21 tend to make the said upward movements of the bifurcated ends of the levers 10 and 12 more positive and bring them to proper operative positions above said screw-formed sections, as in Fig. 2. Said screw-sections 19 on the post 15 are arranged in reversely spiral directions With an independent lever for each of said sections, in order to provide for turning the said post and Wheel 16 thereon in reverse directions for engagement with the switch-points, according to the movement required of said points for switching the car.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. In switch-operating devices for railwaycars, a revoluble and vertically-moving post supported in a vertical position on the cartruck, containing two screw-sections of reversely-formed spiralities, a switch-engaging wheel hung to rotate on the lower end of said post, two bifurcated levers engaging said screw-sections, whereby simultaneous downward and revoluble movements are imparted to said post, and a spring for lifting said post and wheel, combined with two verticallymoving foot-posts in the platform of the car, and connections between said foot-posts and said levers, substantially as set forth.

2. In switch-operating devices for railwaycars, a revoluble and vertically-moving post supported in a vertical position on the cartruck, containing two screw-sections of reversely-formed spiralities, a switch-engaging wheel hung to rotate on the lower end of said post, two bifurcated levers engaging said screw-sections, whereby simultaneous clownward and revoluble movements are imparted to said post, and a spring for lifting said post and wheel, combined with two elbow-levers supported under the platform of the car, a foot-post for operating each of said elbowlevers, and connections between said lastnamed levers and said bifurcated levers, substantially as set forth.

3. The yoke 9, the bifurcated post 15, containing two reversely-formed screw-sections, supported for revoluble and vertical movements in said yoke, the switchengaging wheel 16, hung on said post, a spring to lift said post and wheel, two bifurcated levers hung in said yoke and engaging said screwsections, combined with means between said yoke and the platform of the ear, whereby vibratory motions are imparted to said bifur cated levers, substantially as set forth.
