PLATE AND mmor: FOR RAILROAD GUARD RAILS.

Application filed March 27, 1924. Serial No. 702,306.

The object of my invention is to provide a tie plate of sufficient length to extend under both the guard and the main rail a further object of my invention is to provlde such a plate with a recess to receive the base flanges of the rails, such recess having shoulders at each end, against which the base 7 flanges abut whereby the guard rail and the main rail are held against separating; still a further object'of my invention is to provide in connection with said plate a still further abutment for the guard rail which is seated on the plate against outward movement and abuts the head of the guard rail; and with these and other objects in view my invention consists'o'f the parts and combination of parts as will be hereinafter more fully described.

In the drawings:

Figure 1 is a top plan view of asection of a railroad rail structure showing the guard rail and my invention, the parts being broken away.

Figure 2 is a sectional View on the line 2-2 when-looking in the direction of the arrows.

Figure 3 is a side proved plate.

Figure 4 is a top plan view of my improved plate and guard rail braces.

The reference numeral 1 designates a tie of any suitable construction; 2 is a section of the main rail. and 3 is a guard rail, all of which may be of any desired construction.

According to the general practice now in vogue in railroad construction the guard rail and the main rail are secured together by means of a clamp 4, which clamp in accordance with present practice is secured about six inches ahead of the frog point and holds the main rail and guard rail securely at that point. In accordance with the regular practice this clamp ,4 is secured to the rails by means of the wedge 5, and wedge 6 being placed between the main rail and the guard rail to properly space these rails. The construction thus far described is known practice.

My invention comprises a plate 7 of sufl'icient length to extend under both the guard rail and the main rail and project beyond the base flanges of these rails sufliciently to enable the ends to be spiked down to the ties. This base plate 7 is provided with a recess 8 adapted to receive the base flanges elevation of my im- .abutment 15,

of the main rail and guard rail as shown in Figure 2, said recess having abutments, or shoulders, 9 at each end against which the outer edge of the outer base flange of the two rails abut thereby preventing the rails from sliding lengthwise of the base plate A seat 10 is provided at one end of the base plate 7 at the outer vertical abutment 11. This base plate is provided with spike. openings 12 whereby the plate may be securely fastened down to the tie by means of the spikes 14:, the heads of the spikes 14 overlapping the edge of the base flanges of the rails 2 and 3. I

My invention consists further in the rail the base of which rests upon plate 7 and against the the seat 10 of the shoulder 11 whereby it is held against outward movement, said plate having spike opening 16 which register with similar openings 17 in the base plate. An arm, or brace, 18 extends upwardly from the base 15 and is of a shape adapting it to engage the side of the head and a portion of the web of the guard rail 3 braced'against outwardmovement, or movement away from 18 carries side wings 19 extending from the base 15 which further strengthen the brace. This brace is secured to the base plate 7 and to the tie 1 by means of the spikes 20.

In railroad practicethe guard rail, as is well known, is used to keep the flange of the opposite wheel of the car from catching the point of the frog. The flange of the other whee-l runs in the space between the guard rail and the main rail, and the guard rail holds the flange on the opposite wheel from the frog point. The pressure on a guard rail is always sideways toward the point ofthe frog and so far as I know in the space from the clamp 4 to the ends of the guard rail there has never been anything strong enoughto hold the guard rail from spreading from the main rail.

21 is a base plate flat from end to end and of a length suflicient to extend under the main rail and the guard rail.

It will, of course, be understood that changes may be made in the detail of construction shown without departing from the spirit and scope of the appended claim.

What I claim is:

A guard rail chair including a plate of suflicient length to extend under both the,

end of which is a whereby the guardrail is the main rail 2. This arm' guard rail and main rail, arecess in the uppen face of said adapted to receive the flanges of said rails, each of said Walls tunet, a seat at one end higherbottom of said sidewalls and tioning as an abutmen and positioned of said plate, horizontal plan plate e than the recess a vertical abutment at t and having parallel base he outer end HARRY GOODWVIN.
