UNETE fi'lATES ear-5st tea- B AIL SUPPORT AND FASTENING;

Application filed. March 2, 1921. Serial no. 448,967.

To a? Z whom it may concern Be it known that I, LoUisGREEN, residing at 5 Church Road, Howrah, in the suburbs of Calcutta, British India, a subject of the King of Great Britain, have invented certain new and useful Rail Supports and Fastenings, of which the following is a specification.

This invention refers to improvements in or relating to railway rail chairs or rail supporting means hereinafter referred to as rail chairs and in means for holding and securing rails to such chairs and for looking the tie-bars in position in the case of sleepers which consist of two concrete blocks or pots connected by a tie-bar to maintain the correct gauge of the line.

It is with such resilient rail chairs and their attachments, designed generally for use with flat-footed rails that my present invention more particularly deals, and one of the objects of this invention is to provide a resilient rail chair capable of carrying and seating thereon two or more fiat-footed rails.

I will now describe my present invention with reference to the accompanying drawings, in which Fig. 1 is a longitudinal section through one of my resilient rail chairs, designed for use with cI'OSsing rails of the flat-footed type, showing means for attaching the rails to the chair and locking the tie-bar by means of the special vertical members provided for the purpose and anchored in the concrete in the same manner as the chair.

Fig. 2 is a side view of the bent clip which I use for securing the rails to the chair and for locking the tie-bar in its place.

Fig. 3 is an end view of the same showing a notch therein designed to engage with a corresponding notch in the tie-bar.

Fig. 4c is a plan of the chair, without the rails, showing holes for receiving the bolts which hold the clips in their places, and

Fig. 5 is a transverse section through the chair showing the relative position of therail and one of the two vertical members which hold the tie-bar.

Referring to these drawings:

The resilient rail chair 1 is formed from a metal plate of suitable dimensions, bent into the form of a trough or inverted letter U to the sides of which four or more legs 2 may be riveted.

Or the chair 1 may be made in one piece, out out of one and the same plate, and bent to the required shape. In either case however, the legs may be either' bent back to form a suitable base for fixing thechair upon a metal. or a wood bed or sleeper; or they may be out into tongues opened out to form prongs for anchoring the-chair in a reinforced concrete slab or sleeper 3.

Oval holes 8 are drilled or punched in the rail-seat 1 to take thebolts 7 forming part of the rail-attachment. 1

Two metal uprights 4, provided with slots to take the tie-bar 5, are fixed one on either side of the rail and right under the chair, thelower end of the uprights & being shaped similarly to thelegs of the chair itself and bedded in the same manner in the concrete sleeper 3.

In combination with the chairs above de scribed, I use aspecial device for securing and holding the rails on their chair-seats and for locking the tie-bars with the chairs. This device, which will be referred to as a spring clip 6, consists of a piece of metal bent roughly into an L or quadrant shape, with a notch 10 cut out at one end to engage a corresponding notch 11 in the tie-bar 5, the other end of said clip being bevelled to provide, when fixed in position, a surface having the same inclination as that of the upper surface of the foot of the rail. Near the bevelled end a bolt hole is drilled to correspond with the hole in the chair seat. When the tie-bar 5 has been inserted and locked in the uprights 4: before mentioned, the clip 6 is set with its bevelled end resting on the rail foot and the notched end in the corresponding notch 11 in the tie-bar. A bolt 7 is passed through the registering holes in the clip 6 and the seat 1 and screwed into a nut 9 held below the chair seating. The bolt being tightened causes the clip to bear and press on the tie-bar at one end and on the rail foot at the other.

A similar clip, secured in the same way, is provided on the opposite side of the chair. Then the bolts 7 are fully screwed into their respective nuts 9, the crossing-rails are then firmly held down on their seat.

The uprights 4:, for locking the tie-bar are so positioned as to prevent the nuts 9 turning while the bolts 7 are screwed into them from above. The. bolts 7 when screwed home, cause the bevelled ends of the clips 6 resting on {the foot 'd-f the rail, to press down and tighten their grip mediately the chair seating is deflected b trains passing over the rail. The action of the clip upon the tiebar is similar to that upon the rail.

In order to release the tiebar 5, the bolts 7 must be first unscrewed and removed and the clips 6 raised, the tie-bar may then be lifted and withdrawn from the slot 12. To look the tie-bar this operation must be reversed.

Lateral movement of the rail is arrested by the clips 6 and also by the bolts 7 fitting close up to the sides of the rails. In order to widen the clearance between the bolts 7 it is only necessary to change the clips and drill holes in them to suit the altered distance. Holes 8, in the chair seat are oval to allow for such adjustment without alteration to the chair itself.

What I claim is 1. A railway rail chair of the form of an inverted trough capable of supporting juxtaposed flat footed rails and arranged on its sleeper with its longitudinal axis lying transversely of the rails supported thereon, a central recess in each side of said trough look said tie-bar in position.

trough to allow resilient action of said chair,

a tie-bar to hold the gauge of the rails, uprights anchored in the sleeper and slotted to receive and engage with said tie-bar, metal clips which engage and lock said tiebar and fir over the foot of each of said rails, and locking bolts passed through holes in said clips and in the horizontal seating of said chair and nuts screwed on said bolts to thereby lock said rail 'to said chair and to L. GREEN.
