HIRAM CARPENTER, OF NEW YORK, N. Y.

IMPROVED RAILWAY-CHAIR.

Specification forming part of Letters Patent No. 59,180, dated October 30, 1866.

To all whom t may concern:

Beit known that I, HIRAM CARPENTER, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Railway-Chairs; and I do hereby declare that the following is a full, clear, and exact description ot the same, reference being had to the accompanying drawings, making a part of this specification, and to the letters of reference marked thereon,

My invention relates to railway-chairs provided with india-rubber or other elastic seats for the rails, and holding the rail, or the ends of the adjacent rails, with a loose cheek or separate side piece, that locks into the body of the chair and is wedged by a small key.

To enable others skilled in the arts to which it appertains to make and use my invention, I will proceed to describe its construction and operation with reference to the drawings.

Figure l is a section of the said chair, and Fig. 2 is a plan of the same.

rIhe rail t rests upon the india-rubber bh, which is'retained in a recess ofthe chair, that keeps it from spreading.

The rail is held and supported on one side by the cheek c, which is cast on the main portion of the chair, and on the other by theloose cheek 1,Which is cast separately, and is so made that it locks into the chair in the manner shown, and is secured by the key 7c, by which it is wedged to hold the rail firmly in position.

If the india-rubber Were not confined in .a

recess, or some corresponding means adopted for its protection, it would in course of time be so much flattened or crushed out that it would be of little or no use, and by keying up the loose cheek and compressing the india rubber the excessive range of elasticity is re. stricted to the degree required to avert the concussion of a passing weight.

The base of the chair may be extended to afford a sufficient support on the ballasting of the road-bed, or it may be bolted or spiked to iron or Wooden cross-tics, in the ordinary manner.

As it may not always be necessary to clamp the rail at any other point than at the joints, the intermediate chairs may be made lighter in construction by omitting the loose cheeks. These intermediate chairs may be so placed on curves that their stationary cheeks resist any tendency to lateral displacement, and they may be placed on a straight section of the road with the cheeks of the adjacent cha-irs sustaining opposite sides ofthe rail.

I claim- The railway-chair constructed with an clastic support, combined With a loose jaw that locks into the body of the chair and is tightened by a key, substantially as described.

HIRAM CARPENTER.
