Specification of Letters Patent.
Patented Mar. 11, 1913.
Application filed February 27, 1912. Serial No. 680,276.
To all whom it may concern:
Be it known that I, THOMAS OANFIELD, a citizen of the United States, residing at Hoosick Falls, in the county of Rensselaer and State of New York, have invented new and useful Improvements in Triple Bars, of which the following is a specification.
This invention is an improved triple rail for use on railway tracks, the object of the invention being to provide a rail which has triple heads and shanks united by a common base and which may be turned over twice at its place so as to allow all three of the heads to become worn before discarding the rail, thereby tripling the life of the rail and correspondingly diminishing the cost of maintaining the railway track, another object of the invention being to provide, in connection with the triple rail, an improved form of chair plate for use in securing the triple rail in any of its adjusted positions on the ties, the invention consisting in the construction, combination and arrangement of devices, hereinafter described and claimed.
In the accompanying drawing :Figure 1 is a perspective view of a portion of a triple rail and a chair plate in connection therewith, constructed in accordance with my invention. Fig. 2 is a vertical transverse sectional view of the same on a larger scale.
My improved triple rail comprises a common base or central portion 1 from which extend three radially arranged shanks 2 which are 120 apart. Each shank is formed at its outer side with a head 3. The rail is formed, in the angles between the triple shanks with longitudinal grooves 4 the sides of which are slightly inclined, so that the grooves widen outwardly or in other words, are substantially wedgeshaped, to some extent, cross sectionally.
The rail with its common base, triple shanks and triple heads is an integral structure which is formed by rolling the same in a suitable mill and my improved rail, although it has substantially three times the durability and lasts three times as long as an ordinary railway rail, can be manufacsides of which are slightly inclined and converge upwardly, the said tongue correspending in size and shape cross sectionally with the grooves 41: of the triple rail, so that it may engage the lowermost groove of the rail, as shown clearly in Fig. 2. The lower shanks and heads of the rail bear on the oppositely inclined sides 6 of the chair plate and, hence, the latter forms a suitable support for the base of the rail, as will be understood.
Not only are the triple shanks and heads of my rail very advantageous in maintaining the life of the rail, but the lower shanks and heads by reason of their radial extent, form exceedingly strong and relatively broad bases for the rail so that the rail is prevented from turning under the stress of passing trains. In placing rails on ties, the chair receiving the ends of the rails should extend across three ties, preferably, in order to give a more solid bearing when trains are traveling over the joints between the rails. The lower shanks and heads of the rail are engaged by clips 8 which are secured on the tie or ties by spikes 9 and which present inclined downwardly converging faces 10 which bear against the heads of the lower rail shanks so that the lower members of the rail are wedged between the clips and, moreover, the lower sides of the lower members of the rail are above the tie or ties. Hence, the clips with their downwardly converging opposing faces coact with the chair plate 5 in supporting the rail.
I claim In combination with a railway rail having a common base and heads at the outer sides of the shanks, atie, a chair plate on faces which bear against the heads of the the tie constructed to fit the lower sides of lower rail members. 10 the lower members of the rail and support In testimony whereof I aflix my signature the rail above the tie, and the clips also sein presence of two Witnesses.
