Patented Apr. 14, 1931 PATENT OFFICE Em GEORGE mzgor DUNSMUIR, oamrormm RAIL-OILING DEVICE I Application filed December 1, 1928. Serial No. 322,989.
The present invention relates to a device for oiling the rails of railway tracks.
The principal object of the invention is to provide a device operated by the passage of a train or car for supplying a limited quan-,
tity of oil to the inner ed e of the head of the ra1l for the purpose of ubricating saidrail and the flanges of the wheels passing over it. A second object of the invention is to provide a device which needs no attention other than occasional'filling of an ,oil reservoir. A third object is to provide in such a device means for regulating the amount of oil delivered to thearail upon the passage of each wheel or train. Still further objects and advantages of the invention will become apparent from the following description which should be read with the understanding that the form, construction, and arrangement of the several parts may be varied within the limits of the claims hereto appended without departing from the spirit of the invention. The referred embodiment of the invention wi 1 now be described with reference to the accompanying drawings which are artially diagrammatic in character, an in which- V Fig. 1 is a transverse section of a device embodying the invention, and
Fig.2 is a sectional plan taken on the line 2--2 of Fig. 1 and enlarged In the drawings the reference numeral 3 designates a railway rail, The lubricant is supplied to the inner corner. 4 of the head of said rail through a passage 5 extending through .said head and communicating with a' pipe 6. A'suply of lubricant in a fluid state is containe in a reservoir 7. A piston 8 is closely fitted within said reservoir and rests upon the surface of the lubricant (not shown). A weight 9.is carried by the piston 8 for the purpose of applying pressure to the lubricant.
reservoir 7 to a" valve chamber 11, said chamber being formed as a cylinder in which is a slidable piston 12. The piston 12 is secured upon a stem 13, the lower end of which car.-
' the closin reservoir 7, and that it may be adjusted to A pipe 10 leads from the bottom of the ries a valve head 14 controlling the outlet of p the chamber 11 into the tube .6. ,Th piston 12 is providedvwith ports 15 shown in Figs. 1' and 2.' The stem 13 extends through suit able packing 16 in the upper end of the chamber 11 and is connected with a rocking. arm 17 whose outer end 18 is positioned adj a-- cent the'head of the rail 3 and adapted to beldepressed by a Wheel passing along said rai -When the lever'17 is rocked by the contact of a wheel with its end 18, the valve stem 13 is raised and the valve 14 is opened. The lubricant thereupon flows from the reservoir 7 through the pipe 10, the 'chamber 11, the ports 15 of the piston 12, the valve 14; and the pipe 6 to the outlet at the edge of the rail head. The pressure of the lubricant above the piston 12, which pressure is produced either by the height of the column of lubricant in the pipe 10 and the reservoir 7, or by the weight 9 upon the reservoir piston 8,701 by a combination of both said forces, aided by the weight of the piston 12, stem 13, or lever 17-, causes the valve piston 12 to descend and close the valve as soon as the wheel has passed the lever 17. The speed with which the piston 12 and valve 14 descend determines the' duration of opening of the valve and depends upon the aggregate area of the ports'15 and the pressure of the lubricant above said piston 12. The chamber 11 and piston 12 act as a dashpot to retard of the valve, and such dashpot' effect can e re lated by varying the pressure of the lubricant or. by changing the area l of the ports 15 in said piston 12.
It will be seen that the device is simple and requires no attention other than occa-- sional replenishing ofthe lubricant in the deliver whatever amount of lubricant may be necessary pro erly to lubricate the rail and the flanges o the wheels passing over it.
I claim p A rail oiling device comprising a reservoir adapted to contain a'supply of lubricant, a conduit connecting said reservoir with the rail, a cylinder included in said conduit, a piston operable in' said cylinder adapted to partially restrict theilow of lubricant there- 1m:
through, a valve connected with said piston for closing said conduit, and means operated by the passage of a wheel along saidrail for moving said piston against the flow of 5 lubricant in said cylinder to open said Valve.
In testimony whereof I havesigned my name to this specification;
