- RAIL FOR STE-BET RAILWAYS. No. 369,190. Patented Aug. 30 1887.
. UNITED STATES PATENT OFFICE.
HARDIN H. LITTELL, OF LOUISVILLE, KENTUCKY.
RAIL FOR STREET-RAILWAYS.
SPECIFICATION forming part of Letters Patent No. 369,190, dated August 30, 1887.
Application filed June 3, 1887. Serial No. 240,173. (No model.)
To all whom it may concern.-
Be it known that I, HARDIN H. LITTELL, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and use- ,the novel construction and arrangement of parts, as will be hereinafter described, and pointed out in the claim.
In the accompanying drawings, Figure 1 is an end View of my improved rail. Fig. 2 is a cross-section of the same, showing the chair which supports the rail. Fig. 3 is an end view .of the chair, showing the flange for supporting the head of the rail and the step for supporting the lower end of the shank.
In the drawings, the letter A designates the top of the rail, or that portion upon which the tread of the wheel travels.
A represents the inner flange of the rail, and A? designates the outer flange of the same.
E denotes the girder or shank, which is perforated at e e to receive the bolts act, as shown in Fig. 2.
It will be seen that the girder or shank is formed integral with the under side rail, and
that the'said girder is in a line, or'nearly so, with one side of the head, and the under surface of the flange A extends inward beyond the center of the head A of the rail to form a shoulder, b.
The letter D designates the chair for supporting the rail, which consists of the base 0, having on one side the flange D, provided with perforations ff. The opposite side of the chair is provided with a step, 0, whereby said flange is adapted to support the head of the rail by means of the shoulder b. The shank of the rail is supported in the step c, and the said rail and chair are secured together by bolts, as above stated, passing through the perforations of the flange and shank.
It will be readily seen that the above rail may be readily and easily removed without disturbing any considerable amount of the road-bed, and at the same time the chair need not be disturbed, as the rail can be removed by removing the bolts from the perforations of the chair and shank.
Having described my invention, what I claim is- The combination, with the head of the rail, having outwardly-extending flanges provided with flat upper surfaces, a perforated shank on a line, or nearly so, with one side of said head, and the undersurface of the outer flange extending inward beyond the center of the head of the rail to. form a shoulder, of a chair having on one side a flange engaging the shoulder to support the head of the rail, its other side having a step to support the shank, and the bolts for securing the flange and shank together, as shown and described.
In testimony that I claim the above as my invention I hereunto set my hand in the presence of two witnesses.
HARDIN H. LITTELL.
