H. W. GRAY. RAILROAD 0mm UNITED STATES HENRY W. GRAY, OF CLEVELAND, OHIO, ASSIGNOR TO HIMSELF, AND W. H. ALVORD, OF HOMER, NEW YORK.

RAILROAD-CHAIR.

Specification of Letters Patent No. 25,545, dated September 20, 1859.

To all whom it may concern.

Be it known that I, HENRY IV. GRAY, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Railroad-Chairs; and I do hereby declare that the following is a full and complete description of the construction 7 and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a perspective view, Fig. 2 is a side view, Fig. 3 is a cross section, Fig. i is a top view, Fig. 5 is a view of the under side, Fig. 6 is a view of the grip, and Fig. 7 is a perspective view of a section of the chair.

Like letters refer to like parts in the several views.

The nature of my invention consists in such an arrangement of parts, that the two ends of the rails may be held firmly together and secured to the tie in the usual manner by spikes, and at the same time, to support the tread of the rail by means of flanges that rise upon either side from the base of the chair.

In the several figures, A A represent the railroad rails of the T form.

B 13 represent the chairs, two being required to form a seat. These chairs are made of wrought iron, and are swaged into a proper form, which form is generally represented in Fig. 7. One part of the chair, forms a horizontal plate or wing, upon which the bottom part of the rails rest, as seen at a in Figs. 1, 5 and 7, and by the return of the chair around the edge of the rail, a longitudinal groove is formed, which embraces the two ends of the rail upon each side as seen at e, in section Fig. 3. From the top of the wing of the rail, the chair rises in an arch, inclining inward, toward the underside of the tread of the rail, as seen at 0, so as to press firmly against the proj ecting part, or tread of the rail, thus giving additional support to the ends of the rail, where they meet. The object of having that part of the chair curved or arched, as seen at 0, is to give it greater lateral strength, and thus support more securely, the ends of the Ea ils, embraced between them as shown in The width of the horizontal wings a, are such, that they very nearly meet upon the underside of the rails, as seen at E in Fig. 5. The outer edges F, of the chairs B are made with a convex surface, or are curved outward, or each end from the center being wedge shaped, so that the distance upon the line X, X, in Fig. 5, is greater than at the ends of the chair as seen at K, K. The object of this, I will presently explain.

The two pieces forming the chair, are held in close contact with the rails, by the grips C, as shown in various positions in the several figures, but detached and in perspective in Fig. 6. These grips are made of good wrought iron, the form of which is shown in Fig. 6. After the chairs B, are properly adjusted to the ends of the rails, these grips are slipped over the ends of the chairs and beneath them and the rails, each grip embracing one end of each section, as seen in Figs. 2, 4L and 5. A piece of hoop or band iron D, of suitable width, is interposed between the convex surface F of each section of the chair, and the grips are then driven snugly upon the chairs, the convex surface F upon each acting as a wedge, and in this manner the sections of the chairs and rails are brought into close and firm contact.

When the grips have been driven as far as necessary to bring the sections of the chair in close contact with the rails, the ends of the band D are bent around as seen at (Z, in Fig. 1, and this holds the grips firmly in place. The chair is now complete, and can be spiked to the tie, in the usual manner.

These chairs can be removed and replaced at pleasure, without disturbing the posit-ion of the rails.

lVhat I claim as my improvement, and desire to secure by Letters Patent, is-

Forming the railroad chair of two sections, having the outer surfaces F convex, as described, in combination with the grip C and band I), the several parts being arranged in the manner and for the purpose set forth.

H. WV. GRAY.
