YLIND PACKING FOR HYDRAULIC c No.188,496.
, U NITED STATES PATENT QFFICE. 4
CHARLES E. BOARDM-AN, OF NEW YORK, N. Y.
IMPROVEMENT IN PACKING FOR HYDRAULIC CYLINDERS.
Specification forming part of Letters Patent No. 188,496, dated March 20, 1877; application filed February 17, 1877.
To all whom it may concern:
Be it known that I, CHARLES E. BOARD- MAN, of the city, county, and State of New York, have invented a new and Improved Packing for Hydraulic Cylinders, of which the followingis a specification:
1n the accompanying drawing, Figure 1 is a transverse section on line 00 m, Fig. 2. Fig. 2 is a horizontal section, on line y y in Fig. 1.
Similar letters of reference indicate corresponding parts.
The invention will first be described in connection with the drawing, and then pointed out in the claim.
and is provided with a flange, 0, which fits the deepest portion of the groove B. It also fits the groove closely at the inner surface of the cylinder, but is of such thickness as to leave a small space, d, behind it in the shallower part of the groove B.
When pressure is created in the cylinder, the water passes through the groove a and holes 1) into the space behind the packingring 0, and forces it against the ram as well as against; the outer side of the groove.
Having thus described my invention, I claim as new and'desire' to secure by Letters Patent The combination, with an elastic flanged packing, O c, of a cylinder, having the grooves a B, connected by the water-channels b, as shown and described, so that the packing will not shift, is forced evenly out, and will wear uniformly.
CHARLES E. BOARDMAN.

G. SEDGWIGK,
ALEX. F. ROBERTS.
