GEORGE H. CRANDALL, OF PALMYRA, NE\\T YORK, ASSIGNOR OF ONE-HALE TO HENRY A. CHASE, OF SAME PLACE.
PISTON-ROD PACKING.
SPECIFICATION forming' part of Letters Patent No. 394,156, dated December 11, 1888.
i Application filed November 14, 1887. Serial No. 255,120. (No model.)
To all wi'/m'z, it may con-cam.-
Be it known that 1, GEORGE H. CRANDALL, of Pahnyra, in the (founty of Wayne and State of New York, have invented a new and useful Inprovement in Piston-Rod Paeking's, which iinprovenent is fully set forth in the following specifieation and shown in the acconipanyin drawings.
My invention is a new process relating to o the i'na'iufaeture of paeking-rings for pistonrods, eoniposed of alternate layers of indiaruhber and some fahrie--as cloth, oil, and soapstone-hein forced into the i'terstiees of the su'hstances, to the exclusion of air contained therein, by a pressure sufiicient to cause the oil and partieles of soapstone to enter and ocoupy said spaces, the soapstone hei'ng applied to said rings before and after theil treatment under pressure.
The invention is hereinafter more fully described, and particularl)Y pointed out in the clairn.
Referring to the drawings, Figure l shows a stuffing-'hox in the head of a c'ylinder, with my improved paeking-rings in place, and
2, SJ, and -l, different views of the packing-ring.
Refer-ring to the parts shown in the drawings, A is a part of the. eylinder-hczul; l, the
stuffing-hox, in which to receive the rings of paeking; (l, the screw-oap or gland for the stufting-box; and I), the piston-rod, all substantially of common eonstruetion.
E are the rings of packing' forined fron sheets con'posed of alternate thin layers of cloth and india-rubber, such as are sold in the market, the rings being; eonstructed to have external and internal dianeters to meet the walls of the stuIiing-lox and the pistonrod, respectively. These rings are divided at 40 their sides, as at u, so that they ma \v be placedV upon the rod, as shown. After the rings are thus t'orned they are eovered with pulverized soapstone l v being tunhled in a close receptaele eontaining` that suhstanee and then placcd in a strong' iron reeeptacle eontaining oil and suhmitted to a pressure byneans of a force-punp or other suitahle device. This causes the oil and soapstone to he thoroughly foreed into the minute eavities among the tihers of the eloth and india-rubher fornerly oocupied by air, the latte' being driven out. The inflow of the oil into the iuterstices of the cloth and india-rubher under the pressure brought upon therings is rapid and the particles of soapstone are (farried in with it, the Whole operation oeeupying but a few minutes time. After the ring's are thus treated, they are again tumhled with powdered soapstone to give them a tinal coating' and polish.
The oil is enployed cold or at the temperature of the room occupied by the worknien, as it is found that hot or boiling` oil rots the india-rubber and destroys its elasticity, rondering` it waxy in nature rather than elastic.
lVhat I clain as m v invention is- The process of produoing' paeking-ring's for piston-rods herein deseribed, said ring's being formed of alternate layers of india-ruhher and eloth and divided at their sides, the rings 7o being first tunhled with pulverized soapstone, then submitted to cold oil under pressure, and finall)v again tunbled with soapstone, as and for the purpose set forth.
