RAILWAY-FROG.

I Specification of Letters Patent. Application filed May 12, 1909. Serial No. 4535, 128.

Patented Aug. 17, 1909.

clear, and exact description as will enable any one skilled in the artto which it appertains to make and use the same, reference "being had to the accompanying drawings,

forming part of this specification.

My invention relates to railway frogs and more particularly to that class of frogs provided with movable wing rails which are actuated by the flanges of the wheels of the passingtrains.

' The object of my invention is to provide a frog of the class referred to which will be as simple as possible of construction and at the same time be strong and durable and not likely to get out of order.

A further object of my invention is to provide a frog in which the point may be reversed so as to increase the ength of life of the frog.

in the accompanying drawings which illustrate one form of frog made in accordance with my invention Figure l is a top plan view of a portion of the railway crossing to which my frog is applied; Fig. 2 is a top plan view of .the bed plate; Fig. 3 is a side view of the bed plate; Figs. 4 and a are a plan view and a side view respectively of one of the wing rails; Fig. (3 is an en larged section on the line (i -(3 of Pig. 1;

' Fig. 7 is an enlarged section on the line 7-7 of Fig. 1; Fig. 8 is an enlarged section on the line R-S of Fig. 1; Fig. 9 is a section on the line 9-4) of Fig. 10 and Fig. 10 and Fig. 11 are a side view and a plan view respectively ot the frog point.

Like marks of reference refer to similar parts in the several views oi" the drawings.

15 represents a pair of erossi railway ails forming a portion of a railway crossing and secured to tics 16in the usual manner.

1'? is a bed plate secured to the ties l6 and provided at one end with chairs 18 adapted to receive one end of each of the pair of rails 15. The bed plate 17 is provided with raised portions it) adapted to receive the wing rails which will be hereinafter described. 'lhcse raised portions 15) are provided with shoulders 20 (Fig. 2) againstwhich the ends of the rails 15 are adapted to abut. Adjacentto these shoulders 20 the parts 19 are provided with extensions 21 provided with pivot holes 2 "For receiving the pivot pins 23 ot the wing rails 2st. At the opposite end the bed plate 17 is provided with a point 25 secured between the raised portions 19 on the bed plate 17. This point connects with the opposite ends of the pair of rails 15. tithe point is made alike on its' upper and lower faces, as is shown. in Figs. t. and it). so that it may be i'everscd and thus materially increase the lite oi" the frog as the point is the part of the frog which first wear. out. The wing rails 24 embrace the point 25 as best shown in Fig. 1. in order to move one oi the wing rails from the other. each of said wing rails is providcd with a downwardly projecting lug 2(3 and these lugs" are connected by means of a bolt 27, as best shown in Fig. 7. This bolt passes through openings 28 in the lugs which openings are slightly elongated, as.

.of the wing rails 24 and force it aside and from the bolt 27 draw the other wing rail in position against the point 25 so as to form a continuous track for the tread of the wheel. As the wing rails 2% are pivoted outside of the line of the crossing rails 15 it will be seen that. when the wing rail is moved into the operative position it will abut firmly against one of the rails 15 and thus form a rigid and continuous track for the wheel.

lla ving fully described my invention what i claim as new and desire to secure by Letters Patent oi the l nitcd States is:

1. in a railway frog. the combination with a pair oi crossing rails, of a. fixed point, a pair of independently pivoted wing rails cmbracing said point, said wing rails being free to move under the influence ot' the passing car wheels. and a connection between said wing rails for mining one from the other.

2. In a rail 'ay frog. the combination with a pair of crossing rails, of a fixed point, a pair of ,"ind pendently pivoted wing rails emlu'acing said point, said wing rails to move under the in tluence of the passing car wheels, a. connection between said wing rails tor moving one from the other, and stops for limiting the movement ot said wing rails.

3. In a railway frog, the combination with a pair of crossing rails, of a bed plate, a pointsecured to said bed plate, and a pair of wing rails embracing said point and independently pivoted to said bed plate outside of the line oi? said crossing rails.

4. In. a railway frog, the combination with a pair of crossing ails, of a bed plate, a pointsecured to said bed plate, a pair of wing rails embracing said point and independently pivoted to said bed plate outside of the line of said crossing rails, and stops carried by said bed plate for limiting the movement of said wing rails,

In a railway frog, the combination with a pair of crossing rails, of a be plate, a point secured to said bed plate, a pair of wing rails embracing said point and inde pendently pivoted to said bed plate outside of the line of said crossing rails, downwardly projecting lugs carried by said wing rails, and a connection between said lugs for moving one of said wing rails from the other, said bed plate being provided with re cesses to receive the said lugs.

(S. In a railway frog, the combination with a bed-plate, of a pair of crossing rails secured to one end of: said bed-plate, a point similarly shaped on its upper and lower faces whereby said point may be reversed,

means for securing said point to the other end of said bed-plate, and a pair of movable wing rails cooperating with said point.

7. In a railway frog, the combination with a bed-plate, of a pair of crossing rails secured to one end of said bed-plate, a point similar on its upper and lower faces wherebyv said point may be reversed, a pair of flanges carried by the other end of said bed plate and adapted to receive said point between them, and a pair of movable wing rails cooperating with said point.

8. In a railway frog, the combination with a pair of crossing rails, of a bed plate, a point secured to said bed plate and similar on its under and upper faces, whereby said point is reversible, a pair of wing rails independently pivoted to said bed plate outside of the line of said crossing rails and embracing said point, dmvnwardly projecting lugs carried by said wing rails, a connection between said lugs 'moving one wing, the other, said bed plate being provided with recesses to receive said lugs and stops carried by said bed plate for limiting the movement of said wing rails.

In testimony whereof, I have hereunto set my hand and atlixed my seal in the presence of the two subscribing witnesses.
