UNITED STATES PATENT OFFICE.
GEORGE W. REISINGER, OF HARRISBURG, PENNSYLVANIA, ASSIGNOR OF ONE-HALF HIS RIGHT TO W. O. HIOKOK, OF SAME PLACE.
IMPROVEMENT IN PlSTON-PACKlNGS.
Specification forming part of Letters Patent No. 133,054, dated November 12, 1872,
To all whom it may concern:
Be it known that I, GEORGE W. REISINGER, of Harrisburg, in the county of Dauphin and in the State of Pennsylvania, have invented certain new and useful Improvements in Piston-Packing and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.
The nature of my invention consists in the construction and arrangement of a piston-packing, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, which represents a perspective view of the packing detached.-
A represents the piston-rod; B, the spider; G O, the outside or packing-rings; and D, the inside ring of a piston, said inside ring being straight on its inner side. E is the followerhead, fastened by bolts a at. These parts are constructed in the usual manner for pistons. On the inside of the inner ring D are secured two inclined stops or checks, G G, between which the ring is cut, as shown, to allow expansion. H represents a wedge made to fit in between the inclined cheeks G G, and is made shorter than the same. This wedge is made hollow, or a cavity formed in its outer surface, in which is placed a spiral spring, I, extending out far enough to be pressed in by the follower-head E when the same is placed in position by the bolts a a, by which means the hollow wedge H is forced in between the two cheeks G G, thereby expanding the packing-rings against the inner walls of the cylinder, preventing any escape of steam or fluids from one end of the cylinder to the other. The spiral spring I being on a constant strain by the pressure of the follower-head, it continues its force upon the hollow wedge, thereby keeping up a constant expansive force, taking up any wear upon the outer or packing-rings O O and the inner walls of the cylinder, thereby making it automatic in its operation. When,
by continued wear, the hollow wedge will not expand the outside rings properly, it is only necessary to take out said wedge and line its sides with metal plates, when it will work as well as before, and by this means the piston can be used until the packing-rings O C are entirely worn out.
This device can be applied to any piston using straight rings, such as are in general use, at a very small cost. It is simply necessary to secure the inclined cheeks to the in side of the old ring, drop in the hollow Wedge, and insert the spring, and it is complete. It is, of course, evident that more than one wedge may be used in the same piston by simply cutting the inner ring in as many places as desired, and attaching inclined cheeks on each side of such cut or cuts.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
In combination with a piston having expansion packing-rings, the inclined cheeks G G, wedge H, and spring I, constructed and arranged substantially as described, and for the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 24th day of October, 1872.
G. W. REISINGER.
