UNITED STATES PATENT OFFICE.
IVILLIAINI H. LAW, OF BROOKLYN, NEW YORK.
METALLIC PACKING.
SPECIFICATION forming part of Letters Patent No. 591,670, dated October 12, 1897. Application lcd April 22, 1897. Serial No. 633,363. (No model.)
To all whom, it may concern:
Be it known that I, WILLIAM H. LAW, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Metallic Packings, of which the following is a specification.
This invention relates to a metallic packing for stuffing-boxes and the like, which packing is cheap and simple and adapted to fit a variety of stuffing-boxes; and the invention resides in the novel features of construction set forth in the following specification and claim and illustrated in the annexed drawings, in which- 1 Figure 1 is a sectional view of a stuffingbox with packing. Fig. 2 is a side elevation of packing. Fig. 3 is a plan view of a packing-section or split ring. Fig. 4 is a side elevation of a packing-section or split ring. Fig. 5 is a section along @c fr, Fig. 3. Fig. 6 shows a modified form of stuffing-box.
A piston or rod is shown at l, and a stuif-- ing-box at 2, having a gland or follower 3. The packing is shown consisting of four split rings or sections, each a counterpart of or like all the other sections, so that said sections can be put in place in any order or interchanged throughout, as seen fit. Each ring when sectioned, as along w, Fig. 3, presents the sectional outline 4 5 6 7 8 9, Fig. 5. Each ring or packing-section, as thus seen in Fig. 5, comprises a channeled face 6 7 8 and a ridge-face 9 4 5. The channel 6 7 8 has its edge 6 7 of different length from the edge 7 8. The respective apexes 7 'and 4 of the channel and ridge are out of alinement with one another or not vertically one above the other.
Vhen in place, as seen in Fig. 1,- each packing-section or split ring seats its sides S 9 and V5 G, respectively, against the stuflng-box 2 and the rod or movable part l, and said sections have their ridges 9 4 5 partly inserted into the channels. The parts composing each split ring being suitably separated at the joint or split 10 said split-ring parts can be pressed rmly against said piston-rod 1,and as the sides 5 G of the rings or packing-sections are worn away by the moving part 1 the gland 3 can be tightened to force the ridges 9 4 5 farther into the channels 6 7 8 to take up said wear. Should any section or ring disclose more wear than another ring, the worn ring can be transposed with the ring showing less wear, all the rings being alike. The several rings breaking their respective joints 10 no escape or leak can occur by way of said joints.
The box 2 (shown in Fig. l) has a square seat for the packing, but this packing can also be applied at boxes and glands of different form, as shown at 2' and 3 in Fig. 6. The packing-sections canV be placed v with their apexes 4 facing toward the gland or away from the same, as seen fit.
What I claim as new, and desire to secure by Letters Patent, is-
A sectional packing, the sections of which are formed of split rings each like or a counterpart of the other sections so as t0 be interchangeable throughout, each section having a channeled face and a ridge-face, the channels having their edges of unequal length and the channel and ridge of each section having their respective apexes out of alinement with one another, combined with a stuffing-box and a piston-rod or movable part, said packingsections being made to seat their sides against said box and rod while having the ridges partly inserted into the channels substantially as described.
In testimony whereof I have hereunto set my hand in the p resence of two subscribing witnesses.
IVILLIAM H. LAW. W'itnesses:
JOHN B. KING., ALBERT LAW.
