To aZZ whom it may concern: on the inner side, the two forming together Be it known that I, THORN COPEMAN, a a vertical guideway forthe switch-point rail. citizen of Canada, residing at Edgar Mills, in The housing-plate E is formed on the inthe county of Essex and Province of Ontario, side with a rib f, which is adapted to bear 5 Canada, have invented certain new and useagainst the adjacent face of the cam portion ful Improvements in Railway Switches, of of the roller, as will be more fully hereinafter which the following is a specification. described. The ends of the housing-plate are This invention relates tothat kind of railsecured by bolts 9 g to the stationary rails, way-switch inwhich there are verticallythe bolts g passing through elongated slots 6o IO movable switch-point rails, one being dein the housing to permit expansion to take pressed while the other is at the level of the place without binding the switch-point rail rails; and the invention consists in the peand its supporting cam-roller. culiar and novel means for operating such The-cam-rollers are supported upon ties, swit'clrpoint rails by supporting the same suitable bearing-plateshbeingused,and each :5 upon cam-rollers in the manner more fully cam-roller is provided with a crank-arm F, hereinafter described, and shown in the acconnected in any suitable manner with the companying drawings, in whichswitch-operating rod G.

3. In arailway-switch, the combination with the stationary rails of a main line and siding, of the vertically-movable switch-point rails 0, held in vertical guide-bearings in line with the inner rails, one at the level of the stationary rails and one at a lower level, the cam-rollers D eccentrically journaled to the under side of said switch-point rails and supporting the same directly upon the ties,in alternate positions of said cam-rollers, the arms F on the cam-rollers connected to the switch-operating rod, and the housing-plates E having the ribs f adapted to operate as a fulcrum for the cam-rollers, all substantially as described.
4. In a railwayswitch, the combination with the stationary rails A, B, of the vertically-movable switch-point rails G, the camrollers D upon which said switch point rails are mounted free to rotate saidcam-rollers to support the switch-point rails upon the ties in'alternate positions Of said cam-rollers, one level with the stationary rails and the other below said level, the arms F on said cam-rollers, the switch-rod to which they are connected, and the housings E provided with the ribs f, the aforesaid cam-rollers composed of the roller portions a and cam portions 12 forming between them a longitudinal groove into which said ribs'f project to operate as a fulcrum in rotating the cam-rollers.
In testimony whereof I affix my signature in presence of two witnesses.
