JEFFERSON D. HUEY, OF ST. LOUIS, MISSOURI.

RAIL-JOINT CHAIR.

Specification of Letters Patent.

- Patented Sept. 30, 1919.

Application filed May 25, 1918. Serial No. 236,447.

To all whom it may concern."

Be it known that I, JEFFERSON D. I-IUEY, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented a new and useful Rail-Joint Chair, of which the following is a specification.

This invention relates to improvements in rail joint chairs and consists in the novel construction hereinafter disclosed.

An object of the invention is to provide a rail joint chair which may be readily-assembled in respect to adjacent ends of the rail for supporting the same, and which will be durable in construction and efficacious in reducing the jar and strain upon the track construction at the joints of the rail.

Another object of the invention is to provide a rail joint chair which may be easily applied for supporting the rails at the adjacent ends and readily removed for purposes of repair, which will remove from the rail at the joints all strain in a vertical direction and which provides for the normal expansion and contraction of the rails.

Another object of the invention is to pro vide a rail joint chair which embraces the side Walls of the rail at the jointsand constitutes a support for the bottom of the rail, thereby reducing the wear upon the track construction at the joints and providing a continuous wheel-carrying surface throughout the length of the track construction in which the invention is embodied.

With the foregoing as well as additional advantages attainable from the construction in view, I have designed a rail joint chair as hereinafter fully desoribed,.reference being.

made to the accompanying drawing, in wh1ch Figure 1 is a plan view illustrating the construction of the present invention.

Fig. 2 is a s1de elevation of the rail oint chair embodymg the lnventlon.

Fig. 3 is a side elevation of the opposite side of the rail joint chair of the invention.

Fig. 1 is an end elevation with a section through the rail of the construction of the invention.

Fig. 5 is a cross section taken through the rail joint chair construction and the rail, taken substantially on the line 5-5 of Fig. 1.

Fig. 6 is a sectional detailed view illustrating the means employed for locking the nut of the retaining bolts.

In the embodiment of the invention illustratcd in the drawing, the rail joint chair proper con'iprises a base 1 which has integrally formed therewith a riser 2 which extends inwardly from the base and has an inner surface which conforms to the contour of the side of the rail, thus forming a longitudinal groove 3 into which one of the side flanges of the T-rail extends, a filler port-ion L which extends into the space formed exterior of the web of the rail, the upper portion of said filler 4 constituting a shoulder 5 extending under the lower surface of the ball of the rail. The upper por tion of the riser extends adjacent to the side wall of the ball of the rail and has a flange 6 which overhangs the side edge of the ball of the rail. The upper surface of the riser slopes upwardly toward the center forming an inclined surface which is in approximately the same plane with the upper surface of the ball of the rail at the extremities, and slightly elevated as indicated at 7 above the upper surface of the rail at the joint.

Thus when the flanged Wheels running upon the rail approach'the rail joint, the weight is received and carried by the upper surface of the riser so that when the weight is over the joint it is entirely supported by the riser of the rail joint chair, relieving the rail from vertical strain. The horizontal alinement of the rail extremities is maintained throughout by the support afforded by the chair so that the track construction is maintained in perfect alinement. 7

At the side edges and upon both sides of the base section are extensions 8 which are provided in their outer edge with channels 9 for receiving spikes for attaching the chair in position on the ties of the rail construction.

The opposite side of the base from that from which the riser 2 extends is formed with alternate extensions and cut-out portions 10 and 11 respectively. A filler piece comprising knuckles 12 adapted to seat in the cut-out portions 11 of the base section and an angular plate, formed intcgralthercwith including a horizontal wall 13 and a Wall 14 formed substantially at right angles thereto, constitute a support for the opposite side of the rail, the wall 13 fitting over the upper face of the lower flange of the rail and the wall 1% bearing against the web of the rail and supporting at its upper edge the under face of the ball of the rail.

air M;

to receive a tie-rod or bolt 16 which, after.

insertion in said openings, is held at one end by a bolt head 1 and at the other end by a cotter pin 18. A series of registering

openings

19, 20 and 21 are formed respectivel in the wall 1s of the filler piece in the we of the rail and in the riser.

In applying the rail joint chair to the rails the lower flange of the rail is positioned on the upper face of the base of the rail joint chair and one side of the rail is brought into close contact with the inner face of the riser section. The filler-piece is then placed in position against the other side face of the rail and the rod 16 adjusted in place. The filler piece is then clamped in position by the series of bolts, the heads 23 of which bear against the wall 14: of the filler section. The diameter of the

openings

19, 20 and 21 is in excess of the diameter of the shanks of the bolts, so as to permit. a longitudinal movement of the rails in the rail joint chair caused by the normal expansion and contraction. The tie.

bolts are held in locked position by a series of inner nuts 24 and lock nuts 25.

In order to facilitate the assembly of the tie bolts the riser section is formed with longitudinal channels 26 and recesses 27 The recesses 27 have their inner surfaces formed so as to provide alternate teeth and intermediate spaces as indicated at 28. The lock washer has a: base section 29 the outer surface 30 of which is formed withcomplementarily formed teeth and recesses to fit into the teeth and recesses of the side walls of the recesses 27 in the riser section. The'inner face ofthe lock washer is polygonal so as to fit over the outer nut 25 carried by the tie bolts.

Projecting outwardly from the base section 29 of the lock washer are flanges 31 which embrace the side edges of the outer nut 25. In the sides of the nut 25' are grooves 32 and in the inner surface of the flanges 31 are grooves 33. The lock washers are inserted in the recesses 27 of the riser portion and over the two nuts carried by the tie bolts. The matching faces of the recesses and of the base section of the washer prevent the washer from turning. Pins 34 are then inserted in channels formed by the matching faces of the grooves 32 in the nut and 33 in the flanges of the washer after the bolts have been drawn to the proper adjustment. 7 I

This construction prevents the loosening of the bolts and holds them permanently in position regardless of the vibration caused Copies of this patent may be obtained for by the wheels running over the joint, thus preventing loosening of the parts.

It will be observedthat when the rail joint chair is thus assembled with adjacent ends 'of rails, a rigid clamping support is provided for permanently holding the rails in alinement and affording support throughoutthe surface of the rails, with the exception of the top surface of the ball of the rail from which strain is removed by the upper face of the riser section at the joint.

It will also be observed that the construction permits the ready assembling of the-rail joint chair with the rails, and that the same may be removed for purposes of repair or adjustment without destroying any of the parts thereof, permitting the re-assembling of the construction without loss of material.

I am aware that the invention may be modlfied in I numerous particulars, without departure from the spirit and scopeof the invention. 7

What I claim and desireto secure by Letters Patent, is V 1. A rail joint chair, comprisinga base; extensions projecting laterally from each side of the base and having notches in-their outer'ends adapted to receive the spikesface inclining upwardly from each end to an elevation above the surface of the rail mldway between the ends of the chair; and

means for clamping thevfiller and the riser;

against the rail. 7

:2. A rail joint chair comprising a base; extensions projecting *laterally from each side of the base and having notches in their outer ends adapted to receive the spikes securing the chair to the ties; a rod passing through said extensions at one-side of the base between said notches .and'the bodyof the base; a filler pivoted to said rod and having its outer side inwardly from said notches to permit the heads of the spikes to engage said extensions; a riser at the oppositesides of the base having an upper surface inclining upwardly from each 'end to an elevation above the surface of the rail midway between the ends of the chair; a

flange on the inner side of said riser'bearing upon the upper surface of the head of the rail; and means for clamping the filler and the riser against the rail.
