METALLIC PACKlNG QFjOR STUFFING-BOXES.

SPECIFICATION forming part of Letters IEQatent No; 735,364, dated August 4, 1903.

Application filed November 6, 1902 Serial No. 130.290. (No model.) I

provements in or Relating to Metallic Packing for Stuffing-Boxes and the Like, of which the following is a specification.

- This invention relates to improvements in. metallic packings for stuffing-boxes and the like, and more particularly for the stuflingboxes of gascompressors, especially those used for compressing ammonia or gases of the like tenuity, and I will, by way of example, describe my invention as applied to such stuffing-boxes.

I have illustrated my invention in the accompanying drawings, in which Figure I is a longitudinal section on the line A A of Fig. II, and Fig. II an end view of a stuffing-box constructed according to my invention. 1

In the bottom of the stufling-box l I fit a ring 2, which I will term the bottom ring. This ring is held in place by a sleeve 3, which is a sliding fit in the stufling-box 1 and which is of such length as to be maintained in position by the cover 4, which closes the stuffingbox. Between this cover 4 and the flange 5 of the stuffing-box I interpose a washer 6, of rubber or the like material, and between the bottom ring 2 and the bottom of the stuffingbox I interpose another washer, 7, of the same material, which two washers, in conjunction with the bottom ring 2, the sleeve 3, and cover 4, serve to form a gas tight chamber into which and out of which no gas can escape except that which passes the'packingrrings 8 and 8 of the metallic packing.

Inside the sleeve 3 the metallic packing proper is located, and it consists of two series of antifriction-rings 8 8, of the usual cone type, carried in two containing sleeves 9 and pressed apart by a compressed interposed spring 10, the pressure of which is transmit ted through suitable bearing-rings 11. The

lower containing sleeve bears against the bottom ring 2 and the upper one bears against an end ring 12, which preferably has a spherical seating 13.

The sleeves 9, the spring 10,

the bearing-rings 11, and the two end rings 12 are smaller in diameter than the interior of the gas-tight sleeve 3, and are therefore free to follow any small lateral movement of the rod14.

111 the event of any gas passing the inside of the packing-rings 8 into the gas-tight sleeve I provide means for dealing with it as follows:

I form an annular groove 15 in the inside wall of the stuffing-box and drill one or more holes 16 in the gas-tight sleeve 3, through which the interior of the sleeve communicates with the groove 15, which in turn communicates by a suitable pipe 17 with a receiver or other suitable vessel to which it is desired to lead the gas. The pipe 17 is provided with a flange attachment 18, so that it may be easily dis= connected. I also provide against escape of gas past the outside packing-rings 8 to the atmosphere by forming in the cover 4 an oilchamber 19, in which oil is retained by packing-rings 20, held apart by distance-pieces 21, the whole being held in position by means of a screwed cap 22 and gland 23. Oil is fed into this chamber 19 either by pressure or by grav ity, the oil passing through holes 24 in the distance-pieces 21 into contact with the rod 14, thus forming a liquid seal to prevent leak= age of gas. The oil is fed into the chamber 19 through the passage 19, leaving the same by the upper passage 19.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1 In a stuffing-box, in combination: the rod; the metallic packing fitting the rod; and the gas-tight chamber formed in the stuffing= box and in which the packing is inclosed and which is provided with an outlet through which any gas.which may accumulate may be withdrawn; substantially as described.

2. In a stuffing-box, in combination; the rod; the metallic packing fitting the rod; and the gas-tight chamber formed by a sleeve, an

end washer and ring and a gland, provided 3. In a stufling-box, in combination; the rod; the metallic packing; the ring; the

washer; the sleeve; and the gland provided with a liquid seal consisting of the liquidchamber and packing-rings and means for holding the latter in position, substantially as described.

4. In a stufiing-box, in combination; the rod, the metallic packing, the sleeve, the ring, the washer, and the gland provided with an oil-chamber, packing-rings, distance -piece and means for holding the packing-rings in position in the oil-chamber; substantially as described and illustrated.

5. In a stuffing-box, in combination; the rod, the metallic packing, and the gas-tight chamber having a liquid seal formed by a liquid-chamber containing packing-rings and having an inlet and an outlet for the liquid; substantially as described and illustrated.

6. In combination in a stuffing-box, a metallic packing comprising two sets of packing-rings, containing sleeves in which the two sets of packing-rings are located, a spring interposed between the two sets of rings, the pressure of said spring being communicated to the containing sleeves, and a sphericallyseated ring between one of the sleeves and the adjacent wall of the box, substantially as described.

7. In combination in a stuffing-box, the metallic packing, a gas-tight chamber within the box inclosing said metallic packing and hav ing an outlet to lead the gas away as it accumulates and a chamber for a liquid seal which chamber is provided with an inlet and an outlet, substantially as described.

8. In combination with a stuffingbox a sleeve th erein fitting with its periphery closely against the inner periphery of the box, aring 2 with a washer 7 between the inner end of the sleeve and the bottom of the box, a cover 4 for the box pressing against the end of the sleeve, a washer 6 between the cover and the box and packing means within the gas-tight chamber formed by the sleeve-ring, washers and cover, said packing surrounding the rod, substantially as described.

9. In combination a stuffing-box, a metallic packing within the box, a cover for the box and a sleeve surrounding the packing making a gas-tight joint at one end with the bottom of the box and at the other end with the cover, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses;

HENRY JACKSON GOLD.
