Description
P. P. HA'LL. RAILROAD CHAIR.
No. 21,956. Patented Nov. 2, 1858.
UNITED STATES PATENT OFFICE.
PLINY F. HALL, OF
TROY, NEW YORK.
RAILROAD-CHAIR.
Specification of Letters Patent No.
To all whom it may concern.
Be it known that I, PLINY F. HALL, 0
, Iroy, 1n the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Railroad Chairs or Splines; and I do herein describe and ascertain my said invention, referring to the accompanying drawing, in which Figure l, is a perspective View of the two parts of the chair detached; Fig. 2, the same joined.
The nature of my invention consists in forming a compound chair that will firmly grasp and hold the ends of rails so as to entirely prevent them from working under the action of the train and securing them to the tie by the same bolts that are used to draw the parts of the chair together by which I make a cheap, secure and permanent fastening for the ends of the rails, as easily applied as the ordinary chair and that admits of the easy removal of sections of rail for repair.
The construction is as follows: I form the chair in two parts one of which A, is made with the upper portion a fitting the base of the rail and extending up the web thereof to any desired height so as to securely embrace that portion of the rail. This lip a should fit the form of the rail or nearly so and forms one jaw to grip the rail as hereafter described. From the lower edge of this upper portion of part A, two fiat plates project at Z), 7), on which the base of the rail rests when in place so to leave plates b projecting beyond the base of the rail opposite cz sufiiciently far to receive the other portion of the chair upon it. This latter section of the chair is formed precisely like the first named except in the base plates one 21,956, dated November 2, 1858.
only 0 being attached to it and that at the center of its length which fits exactly between the two plates 1), b, lapping under the center portion of a. This center plate 0 as well as the two plates Z), I), has a hole through it at d near the end. There is an oblong hole in the lower portion 7), 7), and 0 directly opposite the square holes in a and c as distinctly shown in the drawing at 6. These holes are so formed as to produce the effect of a draw bore when a spike is driven through them.
hen the rails are in place and the chair fitted up to them upon the cross tie a spike is driven down through each hole 6 into the tie below. This not only pins the chair down upon the tie but it draws the two jaws together so firmly as to securely grip the ends of the rails and hold them permanently in place. In addition, and for a further security, I form two small bosses 011 the inner side of A at i projecting inward beyond the line of the rail. To fit these I cuta notch out of the base of each rail at or near its end as seen at It Fig. 3, and thus clutch the rail as additional security against the joints being separated.
Having thus fully described my improved construction of chair what I claim therein and desire to secure by Letters Patent is The combination of the plates Z), Z), c and lips or aws a and 0 together with the draw bore spiking of the same by which they are keyed and also wedged and fastened to the tie by one operation all as herein specified and for the several purposes set forth.
PLINY F. HALL.
