Description

UNITED. STATES PATENT OFFICE.
THOMAS TOSTEVIN, OF COUNCIL BLUFFS, IOWA.
r I RAILWAY-RAIL CHAIR.
SPECIFICATION forming part Of Letters Patent N0. 261,498, dated July 18, 1882.
Application filed March 20, 1882. (No model.)
metal, in which the sides of the chair are made to act as braces to receive thelateral thrust of the rail.
The object of myinvention is, further, to construct a railway-rail chair that may be easily adapted to the rail and fitted tightly thereto when first applied, and that maybe tightened readily if it should become loose by use.
The accompanying drawing represents a cross-section of my invention.
In a chair formed of one piece of metal the bottom plate, G, is made wider than the flange of the rail and returned upon itself, leaving the spaces shown at d d and forming the shoulder shown ate c, then fitting or grasping the lower rail-flange, and passing in an outwardly-projecting form to the lower side of the rail-table, against which it tightly fits. The shoulder e e is provided to assist the sides A A (which bear tightly against thelower flange at c c) in preventing side motion of the lower rail-flange. The spaces shown at d d admit of adaptation to rails of varying thickness of flange. The outward projection of the braced sides, preferably made in a curved form, as shown atA A, admits of aready mode of tightening by hammering the curve inward either when first fitted or when loosened byuse. The sides are braced or placed diagonally to receive the lateral thrust of the rail simultaneously at the pointsff, G O, and b b. The ultimate point of bearing being at b b, the sides A A cannot become disengaged, except by describing the are shown at a a, which is prevented by the mass of metal underneath the dotted line.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is'
' 1. In a railway-railchairtormedof one piece of metal, the sides A A, braced diagonally between the rail-table and lower flange, and having an outward projection, as'and for the uses and purposes herein set forth.
2. A railway-rail chair formed of one piece of metal, and having the spaces shown at d d and shoulder e e, as and for the uses and purposes herein set forth.
