UNITED STATES PATENT QFFIGE JOHN N OLAND AND CHARLES NEIDIOH, OF OIL CITY, PENNSYLVANIA.
lMPRdl/EMENT IN PACKINGS FOR PISTON-RODS.
Specification forming part of Letters Patent No. 154,6l3, dated September 1,1874; application nled July 14, 1874.
Letter A represents an ordinary cylinder head and stuffing-box for piston-rods. Letter B represents the gland entering the stuffingbox, and having a steam-joint at E. Letter 0 representsa movable disk, which is pressed against hemp or other compressible material in cavity D, by means of steam in combination with spiral spring G, for the purpose of preventing the escape .of steam or Water between B and F. Letter D represents some compressible material, such as hemp. Letter E represents a steam-joint between A and B, already described. Letter F represents a piston-rod. Letter G represents a spiral spring, which is intended to support the disk 0 while there is no pressure of steam or water through opening H, as, for example, during one-half the travel of the piston on steamengines. Letter H represents the opening Where the steam enters the box.
What we claim as our invention, and desire to secure by Letters Patent, is-
The solid or sliding disk (J, held in place by a spiral spring, G, in cylindrical box A, in combination with the fibrous packing and the stationary gland B, so that the action of the steam from the cylinder may compress the fibrous material to the piston-rod, substantially as described.
