SPECIFICATION forming part of Letters Patent No. 727,839, dated May 12, 1903.
Application filed January 31, 1903. Serial No. 141,339. v(No model.)
T0 all whom t may concern,.-
Be it known that I, OLIVER TADoUs RAY- MOND, civil engineer, a subject of the King of Great Britain, residing at 13 Murray road, Mill Hill, in the county of Middlesex, England, have invented certain new and useful Packing, of which the following is a specification.
The object of this invention is to provide a packing for the stuing-boxes of piston-rods and the like which shall be suitable foruse with steam or water or any high pressure.
Each element of packing, as I may call it, consists of three cores, so arranged as to present a triangular appearance in cross-section, two of the cores, whichk are circular, or approximately so, in cross-section, being laid side by side as concentric rings, while the third lies upon and intermediate to the other two. I preferably place each element so that the two rings are toward the steam-pressure and may be wedged apart by the action of the third when the gland is screwed down; but they may be reversed.
Figure l of the drawings shows diagrammatically a cross-section of such an element of packing. Fig. 2 is a similar view'illustrating a modification in the method of making; Fig. 3, a perspective view illustrating another modification. Fig. 4. shows a pistonrod passing through a stuffing-box with four of my elements of packing. Figs. 5 to 9 show modifications.
In all the figures, a a. are the two concentric cores, and b the A core above them. These cores may be made of any suitable materialsuch as asbestos, cord, rope, or the like-and the three cores may be united, as shown in Fig. l, by a piece of cloth c, wrapped aroundt them and secured by stitching at the points c', or the cloth may be impregnated with india-rubber and be vulcanized after beingr wrapped around the cores, or the cores may be stitched rightthrough, as shown in dottedY lines, Fig. 1, or the whole core may be formed of impregnated cloth. A convenient method of forming an element of such cloth is by laying a sheet of cloth d (see Fig. 2) on a table and rolling up the two sides on `two cores d', and when the two rolls almost meet in the middle the third, h, formed from a separate piece of cloth, is placed on the middle of the preferably cut on the skew, so as to make a The ring-should be just small stufiing-box around scarf-joint. enough to slip into the the piston-rod.
Fig. 4 shows a piston-rodf passing through a stuffing-box g and gland h and packed with four of my elements ot' packing. seen that as the gland is `screwed down the cores b will force the cores a. apart, thus giv ing the elastic contact with the sides of the stufling-boxand rod, that is so desirable.
I always prefer that the core b should be of slightlygreater diameter' in cross-section than the cores a., which, if desired, may be oval in cross-section.
In place of "having the core b cylindrical I may make'it square or triangular in crosssection, as shown at z' andj in Figs. 5 and 6, respectively, and I may alsoput a core 7c 0pposite thecore j, as shown in Fig. 7, or may have two tiers of cores a, as in Fig. 8, to which may again be added a core lo, as in Fig. 9.
What I claim isl. A packing comprising two concentric rings circular in cross-section, and a third ring It Will be situated upon and intermediate to the two of slightly-largerdiametersituated upon and intermediate to the two first mentioned substantially as described.
3. A packing composed of two concentric rings, circular in crosssection, a third-ring situated upon and 'intermediate to the first two rings, and a fabric which secures the rings together, substantially as described.
4. A packing composed of two concentric IOO rings, circular in cross-section, a third ring situated upon and intermediate to the two first mentioned,and a fabricimpregnated with india-rubber and which secures the rings together.
5. A packing comprising two concentric rings, circular in cross-section, a third ring situated upon and intermediate to the two rst mentioned, and a tape which secures the rings together, substantially as described.
G. A packing comprising two concentric rings circular in cross-section, and a pair of rings situated one on each side of and interl mediate to the two iirst-mentioned rings sub stantially as described.
7. A packing comprising four rings circular in cross-section, arranged concentricaliy in pairs and a fifth ringsituated upon and intermediate to the rings of one pair substantially as described.
