UNITED STATES PATENT OFFICE.
GEORGE W. BILLINGS, OF CHICAGO, ILLINOIS.
IMPROVEMENT-1N RAILROAD-SWITCHES.
Specification forming part of Letters Patent No. 1 84,693, dated November 28, 1876; application filed May 27, 1876.
To all whom it may concern:
Beit known that I, GEORGE W. BILLINGS, of Chicago, Cook county, Illinois, have invented an Improvement in Railroad-Switches, of which the following is aspecitication:
Letters Patent'No. 137,050 were granted to me March 2 5, 1873, for a railroad-switch. In that patent I describe re-enforcing bars in combination with the main rails, the latter being constructed with offsets or recesses to receive the ends of the switch-rails, respectively, when the main and switch rails are brought into contact. The recesses referred to are objectionable.
The invention herein described consists of a combination of tapered switch-rails with angle-bars of iron or steel, riveted 0r other wise securely attached to the insides of said switch-rails, respectively, as hereinafter described, the object in view being the ability to construct the main rails without the aforesaid objectionable recesses; also, to prevent breakage of the switch-rails and-the springing of these-rails; and also to afford foundations other than the flanges of these rails as fastenings for the tie-rods of the switch.
In the drawings, Figure 1 represents a plan of a railroad-track and switch embodying my invention; Fig. 2, a transverse section of the same.
contact with the side of the stationary rail a, I
(or the front end of section f into contact with the stationary rail b,) said front end fits in a I little under the head of the stationary rail, as shown. c'andj are angle-bars of iron or steel, riveted or otherwise securely attached to the inner sides of the tapered'rails e and f, re-
spectively. The tie-rods k are attached to the angle-bars i and j,.as shown.
The free ends of the switch-rails c andf are operated by a lever, m, and rod n,in the usual manner.
I make no claim to the tapered rails, sepa- I rately considered; but
I claim- The angular bars '5 and j, in combination with the tapered switch-rails e and f, substantially as set forth, for the purpose specified. v
. GEO. W. BILLINGS.
