UNITED STATES PATENT OFFICE.
OLIN J. GARLOOK, OF PALMYRA, NEW YORK.
PISTON-ROD P'ACKING.
EPECEPICATION forming part of Letters Patent No.33 1-,579, dated January 19, 1886.
Application filed December 13, 1884. Serial No. 150,395. (No model.)
To aZZ whom it may concern:
Be it known that I, OLIN J. GARLOCK, of Palmyra, in the county of Wayne and State of New York, have invented a new and useful Improvement in Piston-Rod Packing, which improvement is fully set forth in the following specification and accompanying drawings.
in the claim.
Figure l of the drawings is a plan of my improved packing-ring; Fig. 2, an edge view of the same, (seen as indicated by arrow in Fig. 1;) and Fig. 8, a longitudinal vertical and central section of the packing-box of a steam or other power cylinder, with a portion of the piston-rod and other parts, showing several of the packing-rings in place around the rod within the packing-box to illustrate the use of the same.
Referring to the parts, A is the ring of packing, made of an internal diameter to fit the piston-rod to be packed, and of an external diameter to correspond with the internal diameter of the packing-box to receive it, the thickness of the ring being preferably about one-fifth of its external diameter. This ring is made up of alternate thin layers of india-rubher, a, and cloth, 0, pressed firmly together, the ring after thus constructed being boiled for a time in a Vat of lard or other oil containing a quantity of plumbago held in suspension. After the boiling process the rings are taken out and allowed to drain, or dried, when they are packed for shipment. The ring is intended to be cut through diagonally at one side, as shown at b, for the purpose of opening it to place it upon the rod, its elasticity causing it to return to its normal or annular shape after being placed uponthe rod, and to closely encircle the rod, as shown in Fig. 3. During thei process of boiling, the substance of the ring becomes thoroughly impregnated with the oil and plumbago, which together lubricate the packing-ring and permit the piston-rod to glide through the same with a minimum amount of friction. These rings are used in the packing-box the same as other packing, being compressed by the gland D in the usual manner, the rings simply taking the place of other kinds of packing commonly used. Packing-rings thus made and prepared are soft and elastic, and when compressed in the packing-box bear lightly and easily upon the sliding rod from their pliable nature, while from the lubricants used in their prepa ration the friction of the rod when sliding through them is much less than where harsher kinds of packing are used. Boiling the packing-rings thoroughly in oil with plumbago tends to drive the latter lubricant thoroughly into the fibers of the cloth and interstices of the indiaTubber, while it softens both and renders them peculiarly adapted for packing piston-rods. From this treatment the indiarubber as Well as the cloth becomes a reservoir for the lubricants, holding them to be gradually drawn upon as the friction of the moving rod requires.
What I claim as my invention is- Oircular rings of packing for piston-rods, cut from sheets built up of alternate layers of india-rubber and cloth, said rings being cut obliquely across at one side, so as to be opened, as shown, and boiled in oil with plumbago held in suspension, as and for the purpose specified.
