Description

1 Improvement in Street-Cars, invented by JOHN ment greatly facilitated whereby the driver is JOHN STEPHENSON, OF NEW YORK, N. Y.
IMPROVEMENT IN STREET-CARS.
Specification forming part of Letters Patent No. 126,757, dated May 14, 1872.
CASE D.
Specification describing a new and useful STEPHENSON, of the city, county, and State of New York.
This invention relates to a new and useful improvement in carsfor street railways, whereby existin gevils are remedied, and the arran geenabled to open and close the entrance-door from the front platform; and it consists in the manner of suspending the door, hereinafter more fully described.
The accompanying drawing is a view of the rear end of a street-car partly in section.
Similar letters of reference indicate corresponding parts.
1t is well understood that a sliding door works more easily when suspended at or near the top on pulleys than when resting on pulleys at the bottom, especially when the foottrack is liable to be obstructed by mud or ice. In suspending the door of a car from the top it has heretofore been found necessary to cut away a portion of the roof of the car and make an unsightly protuberance thereon to accommodate and cover the way on which the suspending pulleys run.
In applying my, improvement I make the way in two sections, A and B, the latter of which is dropped down sufficientl y low to allow of the free movement of the door-sheave without contact with the roof. This arrangement is seen in the drawing. 0 is an an gle-pla-te attached to the side of the door in which the sheave revolves on the way B. D D are the two sheaves. E'is the door. By this arrangement the roof of the car is left intact, and the usual excrescence on the roof of a car is avoided.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The door of a railroad car suspended in a way formed of two sections, A B, arranged sufficiently low to allow of the free movement of sheaves, all as described.
JOHN STEPHENSON.
