Description
tntwa atut Lene-rs Patent No. sont, dated .Tune 1,1869.
IMPROVED RAILWAY-CHAIR.
The Schedule referred to in these Letters Patent and making part of the saune.
To all whom 'it may concern:
Be it known that I, CHARLES A. HARRIS, of lthe town of Owego, county of Tioga, and State of New York, have invented a new and useful Improvement in Chairs for Railroads; and I do hereby declare that the following is a full and exact description of' the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
In theaooompanyiug drawings- A shows the bztse or body ofthe chair.
B is a false side, conforming, on one side, to the side of the rail.
C shows a. drop-block, lilling a space between the false side B and an upright part ot' the piece A, which is held down by one or more bolts, D.
The same letters refer to like parts.
In this chair, the rail sits in the bottom of the chair proper, in the usual manner, one side conforming to the shape. of the rail, and rising well up under its tread or top. Opposite is a false side, B, also fitting the side of the rail, and rising even with its top.
'Ihe false side is held up to the rail, by means of a taper drop-block, C, which is held down by one or more rails would still be held securely; the weight of' the drop-block, and the manner in which it is enclosed,
would prevent it from moving, and allow the false side to become displaced. I
There are fonr smallV projections,c c, which enter the notches or indentations out inthe flanges of rails at their' ends-two on the piece A, and two on the bottom ofthe false side B.
These proiections do not lit the notches in tl'e rails, but allow them to expand and contract, and :tt the `same time prevent them from being driven out ofthe chairs horizontally by passing trains.
l do not claim the use of a clamp-wedge, drawn down by bolts, to hold the ends of rails in position;
hut'
What I do cla-iin, and desire to secure by Letters
