UNITED STATES PATENT OFFICE.
GEORGE ABRAM PARLEE, OF TACHE, CANADA.
RAILWAY-SIG NAL.
SPECIFICATION forming part of Letters Patent No. 659,097, dated October 2, 1900.
Application filed October 4, 1899. Renewed August 9, 1900. Serial No. 26,449. (No model.)
To all whom it may concern:
Be it known that I, GEORGE ABRAM PAR- LEE, station agent, of Tache, in the Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Railway-Signals; and I do hereby declare that the following is a full, clear, and exact description of the same.
My invention relates to railway-signals, and particularly signal targets and lamps outside of way-stations. Its object is to provide a simple, strong, and accurate apparatus by means of which the target and the lamp are operated from Within the station.
The invention consists in the form of apparatus employed and the combination of the parts, as shown in the annexed drawings, in which- Figure l is a side View on a large scale. Fig. 2 is a plan view of the table F and lever D. Fig. 3 is a plan view' of the casting D.
A is a beam extending from the wall of the station and firmly secured ,to the brace A. At the outer end of this beam A a casting B is fitted, having its top portion circular and forming, with the end of the beam, the bearing of the spindle S. Over'B fits the cap 0, which is provided with a raceway for balls or rollers which run in a groove on the top of the casting B. The lamp L fits on the top of the cap 0. The target T is attached to the spindle S. A set-screw S secures the spindle S to the cap (3., A hand-lever D,situated in the station, operates the spindle R. Suitable means are provided for operating the spindle S by the turning of the spindle R, the form shown in the drawings being two pulleys P and P and an endless chain or belt P, fastened to each pulley by screws P and P, respectively. The handle D of the lever D is provided with a spring-catch D which grips the table F and insures the proper amount of turn to the signal-spindle S.
Having now described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. In a railway-signal, a lamp provided with a cap, 0, and a spindle, S, depending from the same in combination with a socketed bearingplate for receiving the spindle, S, a bracket supporting the bearing-plate and antifriotionrollers arranged between the cap, 0, and the bearing-plate, substantially as set forth.
2. In a railway-signal, a lamp provided with a cap, 0, having a depending circular flange, and a depending stem, S, in combination with a bracket, and a circular socketed bearingplate, B, arranged thereon and provided with a circular groove and a series of antifrictionballs arranged in said groove, substantially as set forth.
3. In a railway-signal, a lamp provided with a lower circular cap, as 0, having a depending circular flange, and a stem, as S, depending therefrom, and a target, as T, attached to said stem in combination with a bracket, a
circular sooketed bearing-plate for receiving the stem, S, supported by the bracket and provided with a circular groove, and a series of antifriction-balls arranged in the groove between the bearing-plate and the cap, 0, substantially as set forth.
4. In a railway-signal, a lamp provided with a lower circular cap, 0, and a stem, as S, depending therefrom in combination with a bracket provided with a socketed bearingplate, B, for receiving the stem, S, a turning spindle arranged at a distance from the lampspindle, pulleys, P, P, secured one to the lamp-spindle and one to the turning spindle and an endless belt or chain passing over the two pulleys and fastened to each pulley by fastening means, P P all substantially as shown.
5. In a railway-signal, a lamp provided with a lower cap, 0, having a circular depending flange and a depending stem, as S, provided at its lower end with a target, as T, in combination with a bracket, and a circular bearing-plate as B, mounted on said bracket and provided with a circular groove, antifrictionballs arranged in said groove, a turning spindle parallel to the lamp-spindle, pulleys, P, P mounted one on each spindle, a chain or belt passing over the pulleys and fastened to each pulley by a screw, as P P all substantially as set forth.
I have hereunto set my hand, in the presence of the two undersigned witnesses, at Wabigoon, in the district of Rainy River and Province of Ontario, Canada, this 20th day of March, 1899.
GEORGE ABRAM PARLEE.
