Application led February 5, 1918. i Serial No. 215,556.

To all whom t may concern: l

Be it known that I, EMIL HORN, a citizen of the United States, residing at Marcus, in the county of Stevens and State of Washington, have invented a new and use'ful Rod- Packing, of which the following 1s a specification. i

The subject of this invention is a rod packing wherein metallic rings are held in a suitable packing case, and the objects of the invention are, first, to `provide a packing which will prevent leakage through the joint or stufling box, second, to provide a rod packing which will automatically compensate for wear, third, to provide a` simple,

durable and etlicient rod packing.

With the foregoing and other objects view which will appear as the description` proceeds, the invention resides in the com-,j`

bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

Practical embodiments of the invention are shown in the accompanying drawing,

wherein Figure 1 is a centrallongitudinal section of a preferred form of the device shown in place on a rod;

Fig. 2 is a similar view of a modiied form of the packing;

Fig. 3 is a view in elevation of a portion of one of the rings;

Fig. 4 is a similar view 0f a ,supplemental ring;

Fig. 5 is a view in elevation of another form o'f ring. i

Referring to the drawings by numerals of reference:

ln carrying out the invention, a packing case 1 is provided which has cap 2 threaded thereon at one end and which, at its opposite end, is concaved as indicated at 3.

Within the packing case 1 and having a close sliding lit therewith, is a bull ring 4 which is countersnnk at each end to form recesses for the reception of packing rings, each of which is formed of two rings or sections. One ring or section 5 is split as shown and formed with an annular' flange 7, and has` a lug 8 projecting inwardly from the `flange 7 at a point"diametrically opposite the split in the ring.

The supplemental ring` 6 is also split and is formed to be seated upon the ring 5 within the ange 7. A cnt ont portion, indicated at 9, isprovided at the "split for the reception of the lug 8, which structure prevents the rings turning with respect to each other.

Seated on the cap 2 of the packing case is a split tapering ring 10 which is adapted to enter the tapered opening 12 formed at one end of the throat ring 13. At the other end ofthe packing case a ring 14; is provided which is curved or convex at one face to conformto the concave face 3 of the case. f lIt will be understood that the concaved end `of the packing case the cap; the throat ringg the ring lil and the bull ring all have a close sliding fit on the rod l. The split rings formed of the members 5 and 6 have an interior diameter which is less than the diameter of the rod, and the tapered ring 10 has an interior diameter slightly greater than the diameter o'f the rod.

These parts just described are, as usual, located within the usual stutling box 15, which is closed by its gland 16.

\ The parts are assembled as will be understood from the foregoing and the gland 16 drawn against the stuffing boX by any usual and well known means, (not shown). This draws the ring 10 tightly about the rod and forces the ring 14 firmly upon its seat. The split rings within the packing case act in the usual manner to closely embrace the rod.

In the modified form shown in Fig. 2, a packing case 17 is provided which is odset outwardly at one end to form the annular projection 18 which is threaded interiorly to receive the eXteriorly threaded cap or plug 19.

A bull ring 20 is positioned within the casing with which it has a close sliding fit. This .bull ring is countersunk at each end to form annular recesses for the reception of the split rings 21 which are similar in all respects to the rings heretofore described.

The stuffing box 22 engages the annular projection 18, as shown, while the gland 23 engages the opposed side of said projection 18.

The gland is provided with an oil hole communicating with the enlarged bore of the gland and a swab Q5 may be provided in said bore to properly supply oil to the rod.

The ring 26 shovvn in Fig. 5 is an ordinary split ring divided by a diagonal slit 27. This ring may be usedA in place of the split rings just described, especially Where lo7 pressures are encountered. It may also be used VVin conjunction Withy the other rings Vor cut will be presented to allow the escape of fluid.

Having thus described the invention, What is claimed asneW and sought by Letters Patent, is

l. A rod packing, comprisinga packing case, a bull ring in the case, split rings in the bull ring, a cap threaded to the case, a split tapering ring seated on the cap, a throat ring, having a tapering opening for the reception of the tapering ring, contacting the tapering ring, a stuiiing box and a gland for the stuffing box.

2. A rod packing, comprising a packing case formed with a concaved end, metallic packing in the case, a cap threaded to thc case, a split tapering ring seated on the cap, a throat ring, formed with a tapering open* ing at one; end for the recept-ion of the tapering ring, contacting the tapering ring, a stumng box, and a gland for closing the stufling box.

3. In a rod packing, a rod, a packing case mounted on the rod and having one end closed and its opposite end open and provided with interior screw threads, a bull. ring on the rod and snugly received by the packing case, and provided )vith an annular groove at each of its opposite ends, a packing ring in each of the grooves, one of the packing rings bearing against the closed end of the packing case, and a gland positioned on the rod and threaded on the threaded end of the packing case and bearing against the adjacent packing ring.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two Witnesses.

EMIL HQRN.
