RAIL-CHAIR FOR ROADWAYS AND STREET-CROSSINGS.

Application filed August 27, 1913.

To all whom it may concern Be it known that I, AUGUsT Gr. LIEBMANN, citizen of the United States, residing at Butte, in the county of Silverbow and State of Montana, have invented certain new and useful Improvements in Rail-Chairs for Roadways and Street-Crossings, of which the following is a specification.

This invention relates to railway appliances and particularly to rail chairs.

The main object of the present invention is the provision of a rail chair peculiarly designed for use at country roads, street crossings, floors in terminal buildings, and where tracks are laid on streets.

A further object of the invention is to provide a rail chair of the character above described so constructed as to permit realinement of the rail, provide for a flangeway on either side of the rail, and present a surface extending on either side of the rail to permit of hauling trucks, wagons, etc.

A further object is the provision of a very simple construction for this purpose so designed that the rail may be laterally shifted to bring it to gage without the necessity of removing or readjusting the primary fastenings by which the chair is held to the tie.

A further object is to so construct the chair that all stresses to which the rail is subjected will be properly resisted and the rail braced against vertical, horizontal, and tipping thrusts.

A further object of the invention is to provide means whereby the rail may be readily adjusted without the necessity of tearing up the track and surface flooring in order to accomplish this end.

Other objects will appear in the course of the following description.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of a rail chair constructed in accordance with my invention, the tie and rail being also illustrated. Fig. 2 is a plan view of the rail chair illustrated in Fig. 1. Fig. 3 is a side elevation of the construction shown in Fig. 1.

Referring to these drawings A designates a tie, which may be of any ordinary form Specification of Letters IPatent.

or material, and B designates a rail of standard cross section. Disposed upon the tie A is a base plate 2 which is held to the tie by means of screw spikes 3 of any suitable character. The base plate 2 is formed at opposite ends with upstanding abutments 3. The inner face 4: of each abutment is vertical but at its upper end is inwardly extended as at 5 so as to form an overhanging lip. The inner face 1 of each abutment is longitudinally inclined as illustrated in dotted lines in Fig. 2, the inner face of one abutment being oppositely inclined to the inner face of the opposite abutment. Each abutment is downwardly and outwardly inclined upon its outer face and is formed with a laterally projecting bracket 6, this bracket being formed with a screw threaded opening 7 for a purpose to be later stated.

Disposed upon the upper face of the base plate 2 and between the abutments so as to engage the rail B, are rail braces 8. Each of these rail braces has a downwardly and outwardly inclined inner face and is formed with a basal foot 9 and a head 10, the head engaging beneath the head of the rail while the foot engages upon the base flange of the rail. The body of each rail brace is i11- clined upon its outer face as at 11 so as to coact with the inclined faces 41 of the abutments and wedge thereagainst. Each rail brace is formed on one end with an outwardly and laterally projecting arm or tongue 12 which extends parallel to the length of the base plate and which is slotted for the passage of a screw threaded pin 13, the slot being designated 14. If desired the rail braces and abutments may have cored concavities to reduce their weight. Each pin 13 is screwthreaded in the adjacent abutment 3, as illustrated clearly in Fig. 2, and mounted upon the pins-13, which really constitute stud bolts, are nuts 15 engaging one on each side of the tongue or extension 12. It will be seen now that by loosening one looking nut and screwing up upon the other nut the corresponding rail brace may be shifted longitudinally parallel to the rail and that its wedging face, bearing against the wedging face of the corresponding abutment, will shift the rail laterally. By moving one of the wedging rail braces in one direction and the opposite rail brace in the opposite direction a lateral adjustment of the rail in either direction may be secured and this lateral adjustment may be as slight as desired. After the rail braces have been adjusted they are locked in their adjusted position by screwing up upon the nuts 15.

It is to be noted that the rail braces engage beneath the head of the rail and upon the base flange of said rail, that the braces cannot rise because of the fact that they extend beneath the overhanging lips of the abutments, and that they cannot move laterally accidentally because they are'held by the abutments and are clamped thereon by the belt or pins 13. Itwill further be seen that any tipping strain transmitted to the rail will be translated into a downward thrust against the base flange of the rail. It is further to be noted that the top of each abutment is below the level of the rail and that the upper face of each rail brace is curved downwardly and outwardly so as to be below the upper face of the corresponding abutment. A flangeway is thus provided on either side of the rail for a wheel flange, as shown clearly in Fig. 3.

There rails are laid in streets, at street crossings, on country'roads or 'on floors of terminal buildings, means must be provided to support a wagon'wheel on a level with the rail and close thereto so as to permit of easy hauling of trucks and wagons across the rail. For this purpose I provide flangeway members or housings, preferably in the form of longitudinally extending angle irons 16, the vertical flange of each angle iron resting upon the extremity of the base plate and the horizontal flange resting upon and being supported by the corresponding bracket 6 and abutment. These angle irons, it will be understood, extend longitudinally parallel to the rail and are supported at intervals by the rail chairs. The angle irons are held in engagement with the rail chairs by means of screws 17 which extend through the horizontal flanges of the angle irons and into the perforations 7 of the abutment brackets. By removing these screws it is an easy matter to remove the angle irons and thus expose the adjusting mechanism of the chair. These angle irons 16 not only provide a supporting surface on a level with the tread of the rail and relatively near thereto, but they also house the adjusting mechanism of the chair, preventing snow, ice and mud from collecting there around and thus facilitate the ready adjustment of the chair. It will be noted from Fig. 3 that the horizontal flange of each angle iron 16 terminates in line with the inner face of the lip 5 of the corresponding abutment so that ample space is left for a wheel car or engine flange, this space, however, being too small to permit a baggage truck wheel to enter, and as street vehicles are supposed only to cross railways at regulation crossings, it is obvious that an even surface is provided over the rail.

The bed plate with its upstanding abut- 'ments and the rail braces are preferably made of malleable castings but I do not wish to be limited to this, nor-do I wish to be limited to the use of this form of rail chair in connection with street crossings, roads, etc. i

It willbeseeir that with the rail chair described, the rail may be adjusted laterally without any change in the primary fastenings-S and that this adjustment may be readily secured. The chair may be cheaply made, is thoroughly effective inactual practice and conformsto-the requirements laid down by the Block Signal and Train Control Board of the Interstate Commerce Commission, in that horizontal, vertical and tipping thrusts are resisted and in that the rail may be laterally adjusted without change in the primary fastenings and with out lostmo'tion.
