Description
UNITED STATES PATENT GEEICE-` i CHARLES COFFIN, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF ONE- THIRD HIS RIGHT TO JAMES W. MORRISON, OF SAME PLACE.`
IMPROVEMENT IN INDICATORS FOR RAILROAD CARS.
Specification forming part of Letters Patent No. 139,771', dated June 10, i873; application iled April 23, w73.
To all whom it 'may concern:
Be it known that I, CHARLES H. CoEFIN, of Boston, in the county of Sutt'olk and State of Massachusetts, have invented a certain new and useful Improved Automatic Street-Indicator for Railroad Cars, &c., of which the following is a specification:
The nature of my invention consists in the peculiar construction and organization of a yB', Fig. 2, are tivo drums, about which the.-
shoW or displaying card C is wound. Upon this card C is Written the name of the street, in the case it is used in the horse'car, and of the station, when it is used in a steam-car. The drums B and B are driven by the gears I) D, which, in turn, are driven alternately by the gears E. The gear E has-upon its shaft a pulley, F, which is connected by a belt with the pulley H, the pulley H being driven by the car-axle P, acting through the worrn-gears N M and the shaft L. i The gear E isso hung that, by moving the lever G by the handle G', Fig. 3, it may `mesh with either Dor D. In one case the show-card belt C will run in one direction, and in the other 1in `the opposite direction.
From the aboveit may be seen ythat the'` show-card belt C will move with a proportional velocity in relationuto the velocity of the car, so that the name on the belt C will be displayed at proper intervals.
I am aware that similar devices have been used before, and I do not claim the broad invention.
I claim as my invention-` The combination of the worm-gear N M,
shaft L, and pulley H ywith the belt K, shiftinggear E, drums B and B', and show or display belt C, substantially as described, and for the purpose set forth.
CHARLES H. COFFIN.
