UNITED STATES PATENT OEEIGE0 JAMES R. RENIFF, OF BLOOMINGTON, ILLINOIS.
IMPROVEMENT IN STEAM AND AIR BRAKES.
Specification forming part of Letters Patent No. 160,955, dated March 16, 1875 application filed November 28, 1874.
To all whom Ait may concern:
Be it known that I, JAMES It. RENIFF, of Bloomington, in the county of McLean and State of Illinois, have invented certain Improvements in Automatic Steam and Air Brakes for Railway-Gars, of which the following is a specification, reference being had to the drawing.
Figure l represents a sectional view of cylinder and piston. Fig. 2 shows sectional View of cylinder through H.
M5' invention relates to the peculiarly-constructed cylinder, at both ends ot' which are formed, by the position of the piston C, two air-chambers, A and B, one being larger than the other, the pressure coming through pipe E and=port I in chamber A, and passing under piston, through port or passage G G, into chamber B,f1lling both chambers A and B, and keeplng a constant pressure on both sides ot' the piston C, so that when the supply-pipe E is broken, or the cars are uncoupled by accident or otherwise, the pressure conined in the smaller chamber A instantly escapes, and the piston C is forced forward and over the' ing it back and over the port or passage G GrA to its original posit-ion, and at the same time compressing the air to its original pressure, thus being readyat all times for applying the brakes, the port or passage G G allowing the pressure to become equalized on both sides ot' piston.
I claim- The air-chambers A B of unequal diameters, and communicating with each other through a suitable air passage or port, G, in combination with the piston C, acting as a valve in closing and opening said port or passage, substantially as and for the purpose set forth.
JAMES R. RENIFF.
