GUARD-RAIL FASTENING.

Application filcd Novcmber 11, 1.927. Serial No. 232,641.

My invention relates to an improvement in guard rail fastenings.

It consists of a chair made in an integral piece, so constructed that it rests upon a base plate or other support close to or against the base flange of the main rail, affording a seat for the guard rail, and so constructed that a portion rests beneath one side of the head of the main rail and another portion substantially fits the angle formed between the head and the web on the correspmiding side of the guard rail, a flange or abutment on one end of the base plate confining and receiving stress against the base of the rail, and one end of the seat, which receives the base of the guard rail, receiving the reactionary thrust of the guard rail when engaged by and receiving the pressure of the flanges of the wheels on the main rail.

In the accompanying drawings 1 is a transverse section; and

Fig. 2 is a fragmentary plan view.

The numeral 1 represents a metal base plate having a shoulder 2 at or near one end and an upstanding flange forming an abutment 3, at the oposite end.

The numeral l represents the main rail resting upon the base plate with one edge of the base flange snugly against the shoulder 2.

A chair 5 made in a single piece of metal, preferably cast, is fitted to and rests in the space between the base flange of rail 1 and the abutment 3, where it may be held by spikes or bolts extending through the slots 6 in the base plate on either side thereof.

The chair has a seat- 7 at or near its center to receive the base of the guard rail 8, and an arm 9 extends diagonally to a point where it engages the lower inner surface of the head of the main rail at point A. The main portion 10 of the chair extends upwardly and terminates in an overhang 11, which is fitted more or less closely to the angle formed between the head and web of the guard rail 8, and below this overhang a recess 12 is formed between the overhang and the portion of the base of the guard rail therebeneath, and in this space a key 13 is inserted lengthwise of the guard rail where it is held by a cotterpin 14.

The chair is strengthened by means of ribs 15 practically surrounding the entire edge of the central web of the chair.

The points of stress are at A, B, C, D and 1*. In other words, nressure of a rail flange on the inner edge of the guard rail 8 is transferred to the point C, and the reaction upon the guard rail is at the point B, but the pressure upon the overhang of the chair 10 is at points D, F and A.

This guard rail fastening is easy to apply. It is strong, it distributes the strain, and one of the at vantages is that it is all in one solid, integral piece.

This chair does not engage beneath the main rail at all but the chair extends from the line extending from the under side of the head of the main rail downwardly to the base of the chair. This improved chair purposely clears the main rail except at the sur faces A and F.

The key 13 is merely used to confine the guard rail to its seat.

I claim:

1. A guard rail fastening including a base plate, a main rail, a chair resting on the base plate with means for confining the rail and chair laterally, the chair having a portion resting in contact with the lower surface of the head and with the base of the rail, and provided with a seat, a guard rail held. on the seat, a portion of the chair engaging and approximately fitting the angle beneath the head and web of the guard rail, and a key inserted in the space formed between the overhang and the base of the guard rail.

2. A guard rail fastening including a base plate having a shoulder at one point and an abutment at another, a main rail and a chair resting on the plate and together substantially filling the space between the shoulder and the abutment, the chair having an integral arm and an overhang, and provided with. a guardrail seat at a point between the two, a guard rail adapted to rest in the seat, the arm of the chair en gaging the lower surface of the head of one rail and the overhanging portion engaging the corresponding surface of the other rail, and a key for holding the rail resting in the seat of the chair in place.

3. A guard rail fastening including a base plate having upstanding means on its up per surface, a rail carried by the base plate, a chair mounted on the plate and substantially filling the space between the upstanding means and the rail, the chair made in a single piece and including an arm, an overhang, and a seat between the two, a second ary rail resting in the seat, the overhang engaging the secondary rail and the arm engaging the firstmoentioned rail, and means for securing the secondary rail on the seat.

4-. A guard rail fastening including a base plate, a main rail carried thereby, and a chair mounted on the base plate and having an inwardly projecting arin portion engaging and bracing the base and head portions, only, of the rail.

5. A guard rail fastening including a base plate, a main rail carried thereby, and a chair engaging the edge of the rail base, only, and having an upwardly projecting arln engaging and bracing only the under edge of the headof the rail.
