RAILROAD-CHAIR.

Specification of Letters Patent No. 22,656, dated January 18, 1859.

To all whom it may concern:

Be it known that I, HENRY A. LANDRY, of Camden, in the county of Camden and State of New Jersey, have invented a new and useful Improvement on Railroad Chairs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this speciiication, in which- Figure l, is a perspective view. Fig. 2, is a sectional side view. Fig. 3, is a perspective view of the chair, showing a perspective view of the rails in their place and set in cross tie. Fig. 4 is al section view of t-he chair, showing the end of a rail, and chair bedded in cross tie, and both rail and chair carrying the cone of a wheel, as in actual operation.

Letter o, in Figs. l and 2, represents the projecting piece of metal which is cast on and'chilled so as to harden the running surface which projection may also be made of wrought iron or steel and secured to the chair or rails themselves.

Letter o, Figs. l and 2, represents the support or jams afforded to the rails in their lateral pressure.

Letter o, Figs. l and 2, shows the seat for the rail which rail is wedged up tight into its place against the jam Z), Figs. l and 2, by means of the spikes passed through the holes g, g, Figs. l, 2.

Letter o, Fig. 2, shows the inner side of the projecting piece of iron, which is kept as close to the rail as possible but not so close as to prevent the rail being wedged tightly up into its place by means of the spikes passing through the holes g, g.

Letter CZ, Fig. 2 shows the manner in which I propose to strengthen the back of the chair, so as to prevent fracture, when the weight of the passing machinery is thrown on the top of the projecting piece at a, Fig. 2.

Letters h, 7L., Figs. l and 2, are merely holes for securing the chair in its place on the cross tie. y

Letters j, j, Fig. 3, show the ends of two rails which ought to be kept as close as possible, but when laid in cold weather a space,

letter K, Fig. 3, is obliged to be allowed for their expansion in warm weather, which space K, Fig. 3, is to be supported by the projecting piece as shown at a, Fig. 3. The projecting piece a, Fig. 3, is level with the rails at its two extremities as marked by the letters a, a, but raised a trifle higher in the center where the ends of the rails meet at j, j, Fig. 3 or where the space K Fig. 3, occurs so as to take the weight off the extremities of the rails.

The letters o, o, Fig. 3, show where two small but oblong gains are made in the rails, and partly made to cover the holes of chairs at g, g, Fig. 3, so that the spikes may push the rails firmly into their seats and bring the rails against the jam ZJ, Fig. 4, and as close as possible against the projecting piece a, Fig. 3.

The letters 7L, 7i, Fig. 3, are the spike holes through which the cha-ir is secured to the cross tie m, m, Fig. 3.

In Fig. 4, f, is the rail laid in its seat o, and pressed tightly into its seat and made to bear against the am b, by means of the spike passing through g.

The letter c, Fig. 4 shows the inner face of the project-ing piece a, Fig. 4 in -close contact with f, Fig. 4, in consequence of the lateral pressure of the wheel r, Fig. 4, at the same time the cone of the wheel i, Fig. 4 is partially bearing on the surface of the rail f, and top of the projecting piece a, Fig. 4,

' the entire chair vbeing let into the cross tie about of an inch is firmly secured in its place by t-he spikes g, and 7L, Fig. 4, which pass through the chair and are driven into the cross tie m, Fig. 4.

By this chair I propose to aiford a bearing to the cones of the wheels of locomotives and cars of rail roads thereby preventing the unpleasant jarring of the machinery and the undue wearing of that particular part of the rails of a rail road; these chairs may be made of any required size and strength taking as much bearing from the ends of the rails as persons making them may choose to afford and can also be made to suit any of the rails known or used.

That I claim as my invention and wish to secure by Letters Patent, is

The improvement of a projecting piece of metal either cast on the rail road chair Gl scribed, diseiainiing any right to any painmde of Wrought iron or steel and aixed, tisular form or pattern of Chau' to 'which my and rising up along side of the rails on rali improvement may be applied.
