UNITED sTATEs PATENT oEEIcE.
PETER P. R. HAYDEN, OF COLUMBUS, OHIO.
MANUFACTURE 0F RAILROAD-CHAIRS.
Speccation of Letters Patent No. 8,631, dated January 6, 1852.
T0. all whom t may concern Be it known that I, PETER P. R. HAY- DEN, of Columbus, in the county of F rank- `lin and State of Ohio, have invented certain new and useful Improvements in Railroad- Ohairs; and I do hereby declare that the following is a full, clear, and exact descrip- `tion of the same, reference being had to the accompanying drawings, forming` part of this specification, in whichy Figure l, is a `flat view of a portion of the bar or plate (as it issues from the rolls) out of which the chair is made. Fig. 2, is an edge View of the same. Fig. 3 is a top View of the chair in its finished state, and Fig. 4 is a sectional edge view of the same taken as indicated by the intersecting line 2,2, Fig. 3.
The same letters of reference denote cor# responding parts throughout the` several figures.
The nature of my invention consists in forming the chair out of wrought flat plate or bar iron made` with convex raised surfaces therein, on its one side, which, when the bar is cut to the required length for the formation of a chair,"serve to make the lips thicker at or near the roots, when cut and bent, without incurring any eXtra labor to give additional and requisite strength at those part-s.
To enable others skilled in the art to make and use fmy invention I will proceed more fully to describe it.
A, (Figs. 1 and 2) is a portionV of a wrought iron bar which may be of any convenient length and which at suitable dis-` formed is then cut to `the required length A' bar thus Vand the flat portiony of the bar forming the body or foundation surface of the chair; thus, it will be seen that the lips are -not simply strongerthan if made out of a bar of equal thickness throughout as at present,
them where, by the strain thrownupon them, most is required, viz. at or near the roots, which peculiarity is produced by the convex form of each raisedsurface referred to, and to effect which, with a bar of equal thick# ness throughout, a separate upsetting or welding process would be required, involving thereby extra expense and labor, or it wouldotherwise be requisite to form the chair and its lips outof thicker bar which would make the body heavier than required, so that, in eithercase, my improved chair shows a great economy and advantage.
The bolt or spike holes seen in the chair represented in Figs. 3 and 4 for securing the same to the longitudinal runners or cross sleepers are pierced, or punched out, as` at present.
Vhat I claim as my invention and desire to secure by Letters Patent, is-
Rolling iron plates for railroad chairs upon rollers so constructed that the portions intended to fo-rm the lips of the chair shall have a greater thickness than the rest of the plate substantially as herein set forth.
' PETER P. R. HAYDEN.
