HEEL-RISER FOR RAILWAY-FROGS.

SPECIFICATION forming part of Letters :Patent No. 715,750, dated December 16, 1902. Application filed May 3l. 1902l Serial No. 109,712. (No model.)

The object of my\invention is to utilize steel rails in the production of a durable,

stable, and comparatively inexpensive heelriser for railway-frogs. This and such other objects as may hereinafter appear are attained by the devices illustrated in the accompanying drawings, in which- Figure lis a plan view of a heel-riser. Fig. 2 is a side elevation thereof'. Fig. 3 is a crosssectional view on the line 3 of Fig. 2. Fig. 4 is a like view on the line 4 of Fig. 2. Fig. 5 is a cross-sectional view, corresponding to the line 3 of Fig. 2, of a modified form of my device; and Fig. 6 is a sectional view, on the line corresponding to line 4 of Fig. 2, of the same modified form of iny'invention.

Like letters of reference indicate the same parts in the several figures of the drawings.

In Figs. 3 and 4 I have shown a T-rail reversed and having its head A and web B embedded in a casting of iron C, which has been cast around the rail so as not only to securely hold the head and web of the rail, but also so as to support the anges D and provide a broad base for the heel-riser. Preferably the casting C is cast of such form and dimensions as not only to provide a firm base for the heelriser, but so as to lit snuglybetween the adjacent rails of the frog, to which the heel-riser is securely anchored by means of bolts passing through the bolt-holes Ein the heel-riser. It will thus be seen that I obtain a composite heel-riser having a steel wearing surface or face backed by a mass of cast-iron to which the steel face is securely attached, the riser also Vhaving a wide, stable, and cheap base of cast metal. This form of my device not only enables me to use a commercial form of steel, which may bev readily obtainable at times when an order for a special form could not be filled for many months, `but, in view of the fact that the rail is reversed, so that the under side of its flange is used for the wearing-surface of the heel-riser, it does not matter that the head of the rail may have been worn, and so I am enabled to use discarded rails, which can be readily brought to the desired shape with a minimum of manipulation and can be obtained at much less than the cost of new rails or of even steel billets.

While I prefer the stability aorded by my device when constructed as shown in Figs. 3 and 4, the construction of the riser may be modified by first shearing off the head of the rail in slitting-rolls or in any other suitable manner, in which event theriser will be constructed as shown in Figs. 5 and 6, thereby saving the material composing the head of the rail, which may be used for any other desired purpose.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, a heelriser comprising a steel rail reversed and embedded in cast metal, the under surface of the base of the rail being exposed to form the upper face of the heel-riser, substantially as described.

2. As a new article of manufacture, a heelriser comprising a casting having the web of a steel rail embedded therein and having the under surface of the base of the rail exposed to provide the upper face of the riser, substantially as described.

3. As a new article of manufacture, a heelriser comprising a section of steel rail, a casting cast about said section of rail, so as to nclose the web and support the flanges thereof, the under surface of the rail being exposed to provide the upperface of the riser, substantially as described.

4. A heel-riser comprising a steel rail and a casting cast about said rail, so as to inclose the sides and support the flanges thereof, the under surface of the rail being exposed, substantially as described.

5. A heel-riser comprising a section of rail, and a casting cast so as to surround the web and support the flanges of the rail, the under surface of the base of the rail'constituting the upper face of the riser, ,substantially as described.

6. In a heel-riser, the combination with a IOO :eversed rail, of a casting arranged to inelose of its base shall be the upper face of the riser,

the Web and support the anges of the rail, of means arranged to support the anges of tlhe under surface of the base of the rail conthe rail, substantially as described.
