UNlTED STATES PATENT FREDRTU WEIR, OF (TNCTNNA-YIT, OHIO.

RA! LWAY-FROG.

SPECIFICATION forming part of Letters Patent No. 398,205, dated February 19, 1889.

Application filed May 24, 1888.

T all whom it may concern:

Be it known that I, Fnnnnic (".'\\'n1n,ot Cincinnati, in the county of Hamilton and State oi": Ohio, have invented certain. new and useful Improvements in Railway-Frogs, of which the following is a specification.

This invention relates to the construction of a frog of girder rails adapted to street-railways.

The object of my invention is to provide a strong durable frog which can be cheaply and readily constructed, and one which will stand the strain and wear occasioned by the ears or loaded teams passing over the rails.

The various features of my invention will be fully set forth in the description of the accom mnying drawings, making a part of. this specification, in which Figure l is a top plan viewof my improve ment. F 2 is a section on line a: m, Fig. 1. Fig. is a section on line y y, Fig. l. is a modification of Fig.

The point of the [frog is constructed on the U-shaped casting 1, provided with flanges 2 2 for formin a base-support for said point.

3 3 represent flanges for wing-supports for the girder-rails. These flanges 3 form a tramway to points in rear of the guard-rails.

A A represent the guard or wing rails, which are bent to the desired angle and. secured to the U-shaped point 1. by means of through bolts 5 and t-hi mbles or spacin g-blocks 6, which are provided with holes to receive said througlnbolts.

A modification of the above construction is shown in Fig. 4, in which the flanges 3 of the U -point are bent so as to under or over lap, as desired, the flanges 7 of the girder-rails A.

9 represents rivets passing through said flanges and 7, for uniting said guard-rails to the U-point.

8 represents a base plate, and 10 rivets passing through the lower flanges of the girderrails for securing them at their base to the base-plate 8. This form (shown in Fig. 4) of Fig. 4. 7

connecting the rails is substantially claimed Serial No. 274,973. (No model.)

in the application of even date herewith, Serial No. 27%,91]. The U-point 1 is supported laterally by the thimble or spacing-block 6 and through-bolt 11, which passes through fishplatcs 12, and through the webs of the U -point and spacing-block between the same. This forms a firm lateral support for the webs of the rail. At the same time the fish-plates are allowed to project for an attachment with the main rails of the track. The flanges 8 of U- point 1 are cut oil? between the car-rails A A as the flanges 13 of the wing-rails form the tramway, and they are only required at this point for the support of said tramways. They might, however, be extended. with full length and width, as shown in Fig. 11', and when the through-bolts 5 are employed the rivets 9 are om it-ted Having described my invention, what I claim, is

l. The point of a railway-frog, composed of U -rail 1, provided with the base-support 2 and side flanges, 3, substantially as herein speeifled.

A railway-frog composed of the U-shaped point- 1 and the side flanges, 3, in combination with the guard-rails A A, secured together by riv'ets or bolts, substantially as herein specitied.

3. A railway-frog composed of the guardrails A, having side flanges, the U-shaped point 1, having the lateral side flanges, 3, the through-bolts 5, and the spacing-blocks 6,10- cated on the bolts between the point and guard-rails, substantially as described.

at. A railway-frog composed of the guardrail A A, the U-point rail 1, provided with flanges 3, the side rails being secured together by through-bolts 5, substantially as herein specified.

In testimony whereof I have hereunto set in y hand.

. FREDRIC C. WEIR.
