PATENT OFFICE.

JAMES BRYAN AND EDWARD P. HAINES, OF PITISBURG, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 781,266, dated January 31, 1905.-

' Y Applicationfuea May 20,1904. sesamo. 203,854.

Be it known that we, JAMES BRYAN and ED- WARD P. HAINEs, citizens of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have Vinvented certain new and useful Improvements in Rod-Packing, of which'the following `is a specification. v

The object of our invention is tov provide a new and improved rod-packing; and to this end our invention consists of a new rod-packing, in the novel features of construction, and in the combination and arrangement of parts, all as hereinafter described and claimed.

In the accompanying drawings, which illus- "trate an application of our invention, Figure 1 is a central sectional view of a rod-packing constructed in accordance with our invention; Fig. 2, an end View; and Fig. 8, a detail'view of a form of .metallic ring. A

Referring to the drawings, 1 represents a portion of a water-jacketed cylinder-head of an explosive-engine, and 2 a stuffing-box, as illustrated and asfpreferred. The boX is made in two parts fastened together by bolts 3 and attached to the cylinder-head by means of y bolts 4. When thebox is formed of two parts,

each part is provided with an inner wall or casing 5, and when assembled on a piston-rod 6, as shown, a'fluid-passage is provided bey tween the inner surface of the outer wall ofv the box and the outer surface of the inner wall or casing 5. Fluid is introduced to this passage through a pipe 7 and exhausted ltherefrom through` a pipe 8. The inner Wall is c provided with grooves or recesses 9 and 10,

adapted to receive packing-rings 11 and throttling-rings 12, respectively.

Our invention is particularly applicable for use in connection with an explosive-engine piston-rod, and is designed to obviate the serious diliiculties encountered with piston-rod packings used on explosive-engines as heretofore constructed.

Characteristic and important features of our invention are means for throttling the force of cooling and reducing the pressure of the gases of explosion, whereby we are enabled in connection with either metallic rings,

vas 11, or other suitable packing to provide a -highly-eflicient rod-packing.

I Thet hrottling and pressure-reducing means comprise the two rings 12 and a condensingchamber 13. Rings 12 may be solid or of the form particularly shown by Fig. 3. The purpose of making .the rings of two or 'more segments is to permit themv to be readily applied todthe piston-rod without disconnecting the ro 'i The sectional ring employed should have tight or ground joints and the segments so fastened together as to practically forma solid ring. In the construction shown we employ two rings 12, each bored out to make a neat running lit with the piston-rod and each located in a groove or recess 10, which latter is of suffcient size to allow the ring to adjust itself to 'the alinement of the rod. The condensingchamber 13 is formed between the rings 12 and y the cylinder of the engine coming in contact with the first ring 12'are throttled thereby.A

and the temperature of the gases passing said ring greatly reduced in thecondensing-charnber. The function ofthe second ring 12 is to still further throttle the gases and retain the gases in the condensing chamber. The gases passing the second throttling-ring will be sufficiently reduced in pressure and temperature to be effectively stopped by the packing-rings 11 or some other suitable packing medium similarly situated.

A lubricant may be introduced through small passage 16.

The diiiiculties heretofore encountered in packings for explosive-engine piston-rods have beenchiefly caused by the hot high-pressure gases from the cylinder coming immediately in contact with the pa/ckin'g medium. Our invention avoids this and cools and reduces the pressure of the gases to such a degree that a -metallicring packing or soft packing may be used effectively.

/Vhat we claim isl. In rodpacking, the combination, with a casing provided with annular recesses, throttlingrings surrounding the rod, said rings of less diameter than the annular recesses and located therein, a condensing-chamber between the throttling-rings, and a packing medium. beyond the condensing-chamber.

2. In rod-packing, the combination,with an outer and an inner casing, the inner casing having a series of annular recesses, throttlingrings oi' less diameter than the recesses and located therein, a condensing-chamber formed in the inner casing and located between the throttlingrings and a packing medium beyond the condensing-chamber.

3. In rod-packing, the combination with an outer and an inner casing, a Water-passage su rrounding the inner casing, the inner casing provided with a series of annular recesses, throttling-rings of less diameter than the re- Cesses and located therein, a cond ensing-chamber in the inner casing located between the throttling-rings, and a packing medium beyond the condensing-chamber.

ln testimony whereof we aiiix our signatures in presence of two witnesses.
