EDWARD BRICE KILLEN, OF LONDON, ENGLAND.
KEY OR WEDGE FOR RAILWAY-CHAIRS AND STEEL RAILS.
Specification of Letters Patent.
Patented Dec. 11, 1906.
Application filed February 26, 1906. Serial No. 303,044.
to Keys or Wedges for Railway-Chairs and Steel Rails, of which the following is a specification.
In order to keep the present steel rails rigidly fixed in their chairs, spring keys or Wedges of angled iron have been made and used like a triangle having an apex resting against the inside jaw of the metal chair and having the ends of the arms jammed tightly between the extreme top and bottom of the web or waist of steel rail like a wedge, and in using these spring triangles the jaws of the metal chairs have been continually broken off in driving said keys into position.
In order that my invention may be properly understood and readily carried into effect, I have hereunto appended one sheet of drawings, of which Figure 1 is a perspective view of the springmetal key or wedge embodying my invention. Fig. 2 is a longitudinal elevation of the same. Fig. 3 is a transverse section taken through the line a e of Fig. 2 and constitutes the body of the wedge. Fig. 4 is a transverse section taken through the line to x of Fig. 2 and constitutes the non-engaging end of the wedge. Fig. 5 is also a transverse section taken on the line y 2 also of Fig. 2 and constitutes the driving or engaging tapered end of the wedge. Fig. 6 is a part end elevation and part section of a steel rail and railway-chair to which my invention is applied and Fig. 7 is a side elevation of the same, all hereinafter more fully referred to and described.
My invention relates also to spring-keys a, of a nature such as described, and this spring-key is applicable to all sections and shapes of steel rails b, but has the important feature of having its apex a so shaped as to enable one end of said key a to easily enter or be driven into its required position between steel rail 1) and inside j aw of metal chair a, having its two arms made so that said arms a u assume suitable and variable positions under drive, thereby forming when in position a spring triangle having an apex at, which keys itself against the jaw c of the metal chair 0 when driven home and having a hump a on apex capable of being driven be tween the web or waist b of rail 1) and inside jaw c of metal chair 0 without in any way running the risk of breaking of said jaw of chair in driving home the said triangular key a, and this is efieeted by the suitable and variable position under drive which the arms a a of said triangular key a are capable of assuming. The said arms a a never, even when driven home into position, are wedged against the extreme to b and bottom b of the said web or waist of steel rail 1), but being capable in all conditions and at all times of having the great advantage'of assuming suitable and varying positions in contact with the web or waist b of steel rail 1) without ever jamming itself between steel rail 1) and jaw c of chair 0. The tapering entering end of said key a is suitably tapered to easily enter between steel rail 6 and jaw c of chair 0, and when the hump a (in form of inclined plane) of said key a is being driven in between steel rail 5 and jaw c of chair a there is no risk whatever in breaking jaw c, and yet when said key a is locked in position by the square-shouldered enlargement of on the opposite end it has still a base capable of assuming the required suitable and variable positions under weight of the train, thereby giving to said key a the required elasticity which up to the present can only be obtaine on to-days wooden keys.
I claim 1. A triangular metal key or wedge of the character described, having one end of its apex formed with an inclined hump.
2. A triangular metal key or wedge of the character described having one end of its apex formed with an inclined hump and having the other end of its apex formed with a shoulder.
In witness whereof I have hereunto set my hand in the presence of two witnesses.
EDWARD BEIGE KILLEN.
