Description

QSJGHAGB. Automatic Railway-Buffer.
No. 197,248 Patented Nov. 20, I877.
e/fifesf: In ventur- UNITED STATES PATENT OFFICE.
G. SUMNER OHACE, OF EAST FREETOWN, MASSACHUSETTS.
IMPROVEMENT lN AUTOMATIC RAlLWAY-BUFFERS.
Specification forming part of Letters Patent No. 197,248, dated November 20, 1877; application filed October 1, 1877.
To all whom it may concern:
Be it knownthat I, O. SUMNER (hum, of East Freetown, in the county of Bristol and State of Massachusetts, have invented a new and novel Automatic Railroad Safety-Beam, which invention is fully set forth in the following specification and accompanying drawing, which is a view, in perspective, of a section of railroad with my automatic safety-beam thrown open, so as to allow the cars to pass.
The object of my invention is to-furnish a safety-beam which will operate automatically when cars are shunted upon a siding.
In the drawing, H represents a section of railroad, on each side of which are erected the braced posts A A, to one of which is attached the beam B by the hinge D. The opposite post is furnished with the guide-pin a, the spring b, and the lever-catch O. The guidepin a serves to guide the beam B to and support it in place when closed. The spring 1) serves to hold the lever-catch 0 up when raised, and also to throw the beam B open quickly when released by the lever-catch O, which catch extends along the rail in the direction shown by the dotted line, and is pivoted to the rail at 0, being furnished with the curved end 07, which rises slightly above the rail, so as to be borne upon by the tread of a car-wheel passing over it.
The beam B is furnished with the blocks 6 e,
which are to bear against the tread of the carwheels, so as to prevent the flange of the wheels from cutting into the beam.
When cars are shunted upon the side track the wheels pass over and press upon the levercatch at d, which raises the catch 0 from the beam B, when the spring b acts upon it to throw it open to its fullest extent, where it is held by the gravity-catch E.
The posts A A are set at an angle, so that the beam B may be accelerated by its own gravity in opening.
To close the beam, the gravity-catch E is raised, and the beam B is thrown around against the post A, when it bears against the spring b, which releases the lever-catch 0, when it falls of its own gravity, and catches over the beam B.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
The hinged beam B, provided with the blocks 0 e, in combination with the posts AA, the lever-catch O, the spring b, and the guidepin a, when arranged and operating for the purpose herein shown and described,
C. SUMNER OHACE.
