Letters Patent No. 102,137 dated April 19, 1870.
PISTO-ROD PACKING.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may'coiwern.-.
Be it known that I, HARVEY THOMAS LEE, of Marysville, county of Yuba, State of California, have invented an improved Method of Packing Piston- Rods and Valve-Stems; and I do hereby declare the following description and accompanying drawings are 'suiicienttoenable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements, without further invention or experiment.
My invention' relates to an improved manner of constructing metallic packing-rings for piston-rods 'and valve-stems, in order 'to render the jonttight andv -easily adjustable, if at any time it wears sufficiently cage `of thel s tuiiing-box, one of the rings `fitting directly against the rod, and havingt the beveled edge toward one end of the space, while the other. ringl faces it, as it were, sothat its beveled edge clasps the outside of the frost ling. l
Y When the gland or follower is screwed down against this packing, the last-mentioned ring is forced further over the inner one, causing it to clasp the rod more tightly, while the oute'r one is forced against the ont side of the cage, thus making a tight joint.
Each of these rings is made in two parts, or out, each part having an open space between the ends' that are parallel to the axis of the ring, and onel part clasping or embracing the other in such a position that these spaces maybe on opposite sides; the aforesaid ends being tapered off toa thin edge, so that the two parts together form a ring of which both the outer and the inner circumference are circles.
Referring to the accompanying drawings for a more complete explanation of my invention'- B, the-gland of a stuffing-box, such as. s'in ordinary use for piston-rods, valve-stems, land similar moving joints. -Y
The' piston-rod or stem C, as the case may be,.mov es .back and forward, as shown. In order-to pack this, or
. render it steam-tight and keep it so, I introduce two rings D and E, shown at Figure 2.
These rings are made of any of the metals or compositions whi'ch serve the purposes of packing, and are made in tw'o part-s, the part-s a and a' forming the ring D, and the parts b and b the ring E, so that they can be compressed or enlarged as may be necessary.
The rings are made of considerable thickness at one end, c, and are beveled to an edge at the other end, as shown.
The ring D clasps the rod C, and the ring E is placed as shown in Figure 1, so that its beveled edge clasps that of the` ring D.'
In this position it s evident that when the gland is 'forced down against the packing one of the rings will rest against the inner end of the cage, while the otherA will be forced forward bythe gland.
This causes the ringE to slide further over thev ring D, and force it more closely against the rod, while the outer one E 'will be expanded against the inner surface of the cage,'the parts a, and a of the one ring and the Dll'tS b and b of the other allowing this m04'- tion.
' The cut rings are intended tobreak joints so as to prevent escape of steam through the openings;
` .I make my rings of I,Babbitt metal, or other soft `metal which will adjust itself to its bearings,` under pressure, sudiciently to compensate any change of figure liable to be caused by wear, and the consequent ex-pansion of one ring and contraction ofthe other.
Having t-hns described my invention,
That I claim, and desire to secure by Letters Patent, is-
The packing formed by the two divided beveled rings D and vE,the beveled edge of one tting into that of the other, so that the pressure of the glandv will cause the outer one to'expand againstthe sides of the stuffing-box, Awhile the other is compressed against the rod or stem, substantially as described.
In witness that the above-described invention is claimed by me, I have hereunto set myhand andseal. I
HARVEYT. LEE. [L. s.]
Witnesses: J. L. BOONE, W. R. BOONE.
