RAIL-CHAIR.

Application filed. May 13, 1914.

T 0 all whom it may con cern Be it known that I, AUGUST G. LIEB- nmxx, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Chairs, of which the following is a specification.

This invention relates to a railway track appliance and particularly to rail chairs.

The main object of the present invention is to provide a cheap rail chair so constructed that the rail may readily be adjusted laterally thereon and held in laterally adjusted position and also so formed that the rail may be elevated upon shims.

A fur her object of the invention is to so form the base-plate of the chair that it may be readily and cheaply formed from a rolled section having an approximate form of a channel-iron, the base plate being so formed to provide oppositely disposed parallel abutments, these abutments being disposed at acute angles to the short axis of the base plate, as shown.

A further object is to provide a rail chair so formed that the chair will reinforce and support the screw spikes used therein by not only directly supporting the screw spikes but also by resisting lateral pressure or thrust of the rail upon the screw spikes.

A further object of the invention is to so design the chair that it will be extremely simple and that very few pieces will be required to form the complete chair.

A further object of the invention is to so construct the chair that the rail may be adjusted without the necessity of removing or changing the primary fastenings holding the chair upon the tie.

Other objects will appear inthe course of the following description.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a, perspective view of a tie, a rail and the improved rail chair thereon. Fig. 2 is a plan view of the construction shown in Fig. 1. Fig. 3 is an end elevation of the rail chair, the rail and a portion of the rail chair being in section.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters. q

Referring to these drawings, A repre- Specification of Letters Fatent.

Serial No. 838,371.

sents a rail having a standard cross section and B a tie supporting the rail. Disposed upon the tie is a substantially rhomboidal bedplate 2 having a width approximately equal to that of the tie and having upturned marginal flanges 3 at opposite ends. These flanges, as illustrated in Fig. 2, extend at an angle to the short axis of the bedplate and therefore at an angle to the rail A. The flanges are parallel to each other. Disposed inward of the flanges 3 are the abutments 4. These abutments are spaced from the flanges but extend in the same direction and are parallel thereto. The abutments, as shown in Fig. 3, are higher than the flanges 3. The bedplate 2 is held to the tie by means of the screw-spikes 5. Each screw-spike is formed intermediate its ends with a shoulder 6 designed to bear upon the upper face of the baseplate, and below the shoulder 6 each spike is formed with wood screw-threads 7 for engagement with the tie. Above the shoulder (1', each spike is screw-threaded as at 8 for engagement with the nuts 9. These screw-spikes are inserted between the flanges 8 and the abutments 4 as shown clearly in Fig. 2.

The rail A is held in place between the abutments 4 for lateral adjustment therebetween by the rail engaging members 10.

Each of these rail engaging members has a wedge-like portion which is disposed between the edge of the base flange of the rail and the corresponding abutment and also has a portion which extends over the base flange 3, and a portion which extends over the corresponding abutment and through which each screw-spike passes.

In detail, each rail engaging member comprises a body portion 10 having a web 11 extending over the upper face of the rail base and a tapered wedging portion 12, the outer face of which bears against the adjacent face of the corresponding abutment and the inner face 13 hearing against the edge of the rail base. From the body portion of the rail engaging member at its upper end extends outwardly a web 14 which is grooved as at 15 for the reception of the upper edge of the corresponding abutment. This web 14 is adapted to bear upon the upper edge of the flange 3. The web 14 is longitudinally slotted as at 16, this slot extending parallel to the outer edge face of the web 14, this edge face being parallel to the wall or flange 3. The spikes 5 extend loosely through the slots 16.

It will now be obvious that by shifting one of the rail engaging members in one direction and the other in the opposite di rection, that the rail may be laterally adjusted and that the rail engaging members may be clamped tightly in wedging engagement with the rail and with the abutments 4. It Will also be obvious that by shifting one of the rail engaging members in one direction and driving the other rail engaging member up, that the rail may be shifted upon the bedplate. Inasmuch as the space between the abutments is relatively wide a maximum of lateral adjustment of the rail to gage may be accomplished.

The rail A may be vertically adjusted by inserting a shim or shims between the base of the rail and the bedplate, one of these shims being indicated by the numeral 17. The spikes 5 project sufficiently above the base plate to permit nuts 9 to be turned up upon the portion 8 and thus permit of the elevation of the rail clamping members. Of course, this elevation cannot be extreme without also placing a shim under the outer edge of the rail clamp between the rail clamp and the top of the short abutment or flange. This will permit any required amount of vertical adjustment to the rail.

The object of providing the inner flanges 4iconstituting the abutments is to brace the rail clamps against the lateral thrust of the rail and resist any thrust directly to the spikes. The outer flanges 3 reinforce the shoulders 6 of the spikes and prevent any bending of the spikes by the thrust of the rail clamps. It will be seen that the rail clamps extend over the flanges 3 and 4 and protect these flanges in case of derailment and also protect the spike. It is to be particularly noted in this case that by forming a length of channel-iron with the flanges 3 and 4 which structural element may be readily formed by rolling, and then by cutting the channel-iron so formed at intervals diagonally to the side edges of the channeliron, these base-plates or bedplates which are provided with lateral flanges extending at an angle to the line oi the rail supported upon the bedplate can be secured at a very reasonable cost. Thus it requires no special mechanism for the construction of these bedplates other than the usual appliances in rolling mills and said bed plates may be constructed very cheaply. The rail clamps 10 may also be made of rolled material. The chair described has only three pieces exclusive of the spikes and nuts. The adjustment of the wedging rail clamps may be easily accomplished by a section hand without the aid of any other tools except the or in ry rackman nch or j t ng the Wedging clamps Thus, it is an easy matter to adjust the rails to gage. Inasmuch as in order to adjust the rails to gage and in order to shim the rails, it is not nec essary to remove the primary fastenings of the rail chair, it is obvious that this adj ustment of the rails may be made with a minimum of labor and without the necessity of removing or changing the primary fastenings.

One of the great objections to the present method of holding rails to ties is due to the fact that any change in the adjustment of the rail requires respiking of the ties. As a consequence, these ties last but a relatively short time and soon become spike killed and have to be renewed. It is for this reason that it is economically impracticable for railroads to use treated ties. These treated ties where they are not often respiked will last very much longer than the untreated tie but the constant re-spiking of these ties renders them shortly of no value and they have to be renewed. The improved rail chair may be applied to a tie which would ordinarily be thrown away because of its being spike killed and sufficient additional life may be secured over a much spiked and prematurely renewed tie to pay for the initial cost of the chair.
