DERAILER.

Application filed July 8, 1915.

1/ b all whom it may concern.

Be it known that I, Ezna SMYTH, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Derailers; and T do 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 appe'rtains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in railway appliances generally, more especially for derailing cars.

The invention has for its object, as indicated, primarily, to effect the derailment of cars.

A further object is to provide for readily and expeditiously carrying out the aforesaid end especially by lever action.

A. still further object is to provide for readily shipping the lever controlled-derailing appliances to the track-rails in effecting the derailing operation or taking the same out of use.

The invention therefore consists of certain instrumentalities and features of construction substantially as hereinafter fully disclosed and defined by the appended claims.

In the accompanying drawings is illustrated the preferred embodiment of my inntion wherein will be understood that "arious changes and modifications may be made as to the detailed construction and arrangement of parts without departing from the scope of the claims, and in which drawings- Figure 1 is a general plan view of my device showing the manually controlled lever for effecting the shipping of the derailing appliances into and out of use. Fig. 2 is a vertical transverse section thereof. Fig. 3 is a bottom plan view of the device. Fig. 4 is a longitudinal or side elevation of the same. Fig. 5 is a vertical longitudinal section taken on the line 5-5 of Fig. 1.

In carrying out my invention, I provide a plate-like member or shoe 1 which is applied to a track-rail A as illustrated in the showing of Figs. 1 and 5. The shoe or member 1 has upon its upper surface a camlike elevation 2 positioned to aline with the rail A, itself having a rounded upper sur- Specifieation of Letters Patent.

face sloping at both ends as at 2 toward or in the direction of the rail, as seen in Figs. 2 and 4. Also upon the upper surface of the shoe is a second cam-like elevation 3 also sloping or tapering at both ends as at 3, the cam-like elevation 2 being beveled or tapered laterally toward its rear end and in a direction away form the cam-like elevation 3, the latter cam-like elevation extending diagonally of the longitudinal surface or length of the member '1 and parallel with the general tread of the laterally beveled or tapered surface of the cam-like elevation 2 and, while its forward end is directly opposite the corresponding end of the canrlike elevation 2, its rear end is. considerably distant from the rear end of the latter, all as clearly seen in Fig. 1. Thus, with the parts positioned as in Fig. 1, as the car-wheel is moved from the rail, upon the camlike elevation 2, the wheel-face will be elevated thereby so that its flange will be lifted and caused to travel upon the upper surface of the shoe and the wheel, by the contact which is thus effected between its flange and the cam-like elevation, will be caused to travel diagonally or laterally along the upper surface of the shoe, the wheel-face descending the rear sloping surface of the cam-eleva tion 2 and the wheel-flange at an interval farther along leaving the shoe, the same being directed in its movement by the extended cam-elevation 3 in the required di rection, provision thus being made for the requisite derailment of the car.

The shoe or member 1 is pivotally supported at a lateral edge upon a suitable structure or frame work 1, itself suitably p0 sitioned and bolted to the track-rails preferably as shown, and to this frame-work suitable connection is effected for suitably supporting a rock-shaft 5, said connection preferably including a skeleton-like member 6 having horizontal bar-extensions 7 formed with transverse terminals 8 having connected thereto, by bolts 9, members of the frame-work i and within which latter is directly supported the rock-shaft. The rockshaft has suitably extending therefrom a crank-arm 10 having pin and slot connection as at 11 with an angular rod-connection 12 suitably guided as shown and to which is suitably connected a manually controlled lever 13 suitably fulcrumed in position as at 14, for suitably disposing the shoe 1 in position upon the track-rails or removing it tl'ierefrom, as presently more fully made apparent. The pivotal connection or support of the shoe or member 1 includes disk-like arms 15 integral edgewise therewith and carried by the rock-shaft 5 as seen particularly in Fig. 5. The shoe or member 1 also has depending from its underside and its outer lateral edge integral projections 16 and 17, respectively, the projections 16 extending downwardly, alongside of the rails, and the projection 17 being received within a pocket 18 integral with the structure l, this arrangement serving to brace the shoe and retain it against lateral displacement, under strain from weight and pressure as a car is being derailed, the structure l also being braced by means of props 1O suitably bolted to the ties.

From the foregoing, it will be oiserved that, when the shoe is out of use, it is disposed or swung back inverted, as indicated in Fig. and that, when it may be desirct to bring it into use, this may be done by suitably operating the lever 13, the dead" weight or resistance being eased olf by gripping the shoe at 20, it being somewhat extended tliereat for that purpos and exerting upward pressure thereon, while the lever is being actuated, as will be appreciated.

I claim- 1. A ear-wheel derailing device, including a skid-like member or shoe adapted to be ap plied to a track-rail, said shoe having upon its upper surface cam-like elevations, one cam-like elevation being at a rear corner-edge thereof and itself having a rounded or con vex upper surface alining with the rail, with its inner lateral edge beveled and tapered toward the opposite or off edge at its forward end, the other cam-like elevation also having a rounded or convex upper surface and extending diagonally of said shoe, with its inner lateral edge substantially parallel with the corresponding edge of the aforesaid camlike elevation, its forward end extending considerably beyond and to a point nearly in alinement with the forward end of the aforesaid cam-like elevation, said cam-like elevation having their upper convex surfaces produced upon curved lines whose terminals at one end of the shoe are at opposite points, the convex surface of one of said cam-like elevations having its opposite terminal about midway the convexity of the other cam-like elevation. 5 5

2. A derailer, including a pivotally supported shoe, means for its attachment to a track-rail, said attaching means having a pocket, said shoe having pendent lugs upon its underside and at its lateral free ecge, said lugs extending downwardly alongside of the track-rail and received by said pocket, respectively.

3. A car-wheel derailing device, including a pivotally supported skid-like member or shoe, means for its attachment to a track-rail said means being provided with a pocket, said shoe having upon its upper surface cam-elevations, one cam-lile elevation being at a rear corner edge thereof and itself hav- 7 0 ing a rounded convex upper surface alining with the rail, with its inner lateral edge beveled and tapered toward the opposite or off edge at its forward end, the other cam.- like elevation also having a rounded or con- 7 5 vex upper surface and extending diagonally of said shoe with its inner lateral edge substantially parallel with the corresponding edge of the aforesaid cam-elevation, its forward end extending considerably beyond and to a point nearly in alinen'ient with the forward end of the aforesaid cam-lil e elevation, said shoe having pendent lugs upon its underside and at its lateral free edge, said lugs extending downwardly alongside of the track-rail and received by said pocket, respectively.

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

EZRA SMYTH.
