ATTQRN Patented Feb. 9, 1932 UNITED STATES PATENT OFFHCE EMIL IE. HOLIN GER, OF NEW YORK, N. Y., ASSIGNOR T CHASE APPLIANCE CORPORA- TION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK CUSHIONED CHAIR FOR RAILWAY RAILS App1ieation filed February 10, 1930. Serial No. 427,115.

vide a simple, durable, rugged, and efiicient chair for railway rails, which will effectively support the rail and with equal efliciency insulate it from the chair and the surrounding and associated objects, a feature which is especially desirable on railways where electrification is in vogue and for use in systems where the track is used as the ground return.

A further object is to provide a simple and quiet rail and chair assembly to eliminate as much noise as possible, and particularly such as can be simply and easily operated to quickly and surely hold the railin position and where the creeping of the rail in the chair is substantially prevented.

Further and more specific objects, features, and advantages will more clearly appear from the detailed description given below when taken in connection with the accompanying drawings which form part of the specification and which illustrate one present preferred form of the invention and in j which,

place in the chair;

Fig. 2 is a plan view thereof;

Fig.3 is a cross section through the rail and the chair;

Fig. 4 is a side view of Fig. 3;

Fig. 5 is a top plan view of the rail wedges;

Fig. 6 is a side view of Fig. 5;

Fig. 7 is an end view of Fig. 5;

Fig. 8 is a side view partly broken away of a modified form of the invention: and,

Fig. 9 is a similar view of a further modification.

As shown in the drawings, the invention includes a rail chair 11 fastened to a tie 10 of any suitable material but shown as a metal tie. As usual the chair has the inclined upwardly extending side flanges 12 and 13 with bracing members 1% and 15.

A rail is disposed in the chair and has a base 16, a web 17 and a tread 18. Disposed between the rail and the side flanges 12 and 13 of the chair are pairs of wedges 19, 20 and 21, 22 preferably of wood and in most cases of insulating material. These wedges are adjustable by means of bolts having stems 23 and nuts 2A and heads 25. As shown in the figures the plane of contact of the respective pairs of wedges is such that when they are tightened to jam in between the rail and the chair, the line of force exerted is along a plane extending substantially from beneath the head of the rail to a point in line with the adjacent and respective corner of the chair. Being of wood these wedges act as cushions between the chair and the rail to insure quietness, and when made of treated wood or rubber or similar material also have insulating i qualities which are important in connection with electrified roads.

Disposed between the bottom of the rail and the chair is a cushioning member of resilient and insulating material 26 the sides of which 27 and 28 extend upwardly between the chair and the sides of the web or base 16 and 17 to space them. The ends of'the cushion shown as 29 depend over the ends of the chair.

As shown in Figure 8, the chair has a recess 30 into which part of the cushion pro jects to lock therewith and in Figure 9 the chair is cut through to provide a hole 31 into which a portion 32 of the cushion projects to form a positive locking engagement therebetween.

Thus it will be appreciated that the rail is firmly held in position on the chair and prevented from creeping and that it is completely insulated from the chair at the same time. The tighter the wedges are adjusted the more securely will the rail and the cushion be forced into place. 7

The material used in the cushion and the wedges is preferably heat resistant and water proof and having insulating qualities as to electric current so that the rail may well be used as the ground return as is often desirable. Such material may be rubber bakelite or prepared wood.

While the invention has been described in detail and with respect to present preferred form thereof, it is to be understood that there is no intention of limiting it to such details and forms since many changes and modifications may be made and the invention embodied in other forms without departing" l.
