RAIL-CHAIR.

Specification of Letters Patent.

Patented Nov. 9, 1920.

.2 0 alt whoa/L it may concern:

Be it known that I, Bonner E. EINSTEIN, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Rail-Chairs, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to rail chairs, namely, devices of the kind that are used for supporting a rail in an elevated position above a track tie.

The object of my invention is to provide a strong and rigid onepiece rail chair that is inexpensive to manufacture and of such design that a rail can be securely connected tosame by bending portions of the chair into engagement with the base flange of the rail.

To this end I have devised a rail chair that comprises a horizontal web on which the base flange of the rail rests, a pair of vertical walls carrying said web and extend ing the entire length of the chair, and rail holding portions integrally connected to said vertical walls and formed by portions that are severed from said horizontal web. The chair is provided with horizontally-disposed flanges which rest upon the track tie that supports the chair and gussets are preferably arranged at the junction of said flanges and the vertical walls of the chair so as to reinforce and strengthen said walls.

Figure l of the drawings is a perspective view of a rail chair constructed in accordance with my invention; and

Fig. 2 is a similar view, showing how the rail holding portions are adapted to be bent downwardly into engagement with the base flange of the rail supported by the chair.

Referring to the drawings which illustrate a rail chair constructed in accordance with my invention and formed from a sheet of metal that is forged or pressed into shape, A designates the horizontally-disposed web of the chair on which the base flange of the rail rests, B designates a pair of parallel, vertical walls that extend longitudinally of the rail and carry said web and C designates horizontally-disposed flanges that project laterally from the lower ends of said walls B so as to form a wide, substantial bearing sur-' face for the chair on the track tie to which the chair is connected, said flanges having holes 1 in same through which fastening devices can be driven into the tie. The chair is equipped with rail holding portions 2 that are integrally connected to the vertical walls B and which are formed preferably by severing portions of the horizontal web A and bending said severed portions upwardly, as shown in Fig. 1. After the rail has been arranged in operative position on the chair, with the base flange of the rail supported on the web A, the rail holding portions 2 are bent inwardly and downwardly over the base flange of the rail into the position shown in Fig. 2, thus securely connecting the rail to the chair. The parts 3 of the web A that lie between the severed portions 2 are retained so as to form extensions at the ends of the web A that provide additional hearing surfaces for the base flange of the rail supported by the chair. If desired gussets A may be provided at the intersection of the vertical walls B and the tie engaging flanges C so as to reinforce and strengthen said walls.

A rail chair of the construction above described can be manufactured at a low cost, as it can be formed from a sheet of metal forged or pressed into the shape shown. A rail can be attached to the chair quickly and easily by simply bending the portions 2 inwardly and downwardly into engagement with the base flange of the rail and such a chair is exceptionally strong and rigid, owing to the fact that it is provided with reinforced vertical walls 13 that extend through-.

out the entire length of the chair. The horizontal web A forms a wide substantial bearing for the base flange of the rail, and as said base flange is gripped securely at four points by the rail holding portions 2, there is little liability of the rail pulling loose from the chair.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A rail chair provided with a pair of parallel, vertical walls that extend longitudinally of the rail, tie engaging flanges projecting laterally from the lower edges of said walls, a horizontally-disposed web connected to said walls for supporting the base flanges of the rails and provided at its ends with extensions that lie in the same horizontal plane as said web, and oppositelydisposed rail holding portions integrally C011- iected to said vertical Walls and adapted to be bent into engagement with the base flanges- 'Of the rails, sald rall holding portions being arranged 1n transverse alineinent withsaid extensions. V

2. A rail chair provlded with tie engagin portlons, a rail supporting portion arrange V in a higher horizontal plane than said tie engaging portions and consisting of a horizontally-dlsposed web, vertical walls that carry said web and connect 11: to said tie engaging portions, and a pair of integral rail and then bending said severed sections upwardly at an angle to said web.

A one-piece rail chair, comprising a horizontally-disposed web integrally connected to a pair of parallel, vertical Walls that extend longitudinally of the rails integral tie engaging flanges projecting laterally from the lower edges of said vertical walls, oppositely disposed rail holding portions projecting upwardly from said vertical Walls at the ends of said web, integral extensions on the ends of said web that lie un- ROBERT E. EINSTEINv i flanges.
