METALLIC PACKING.
SPECIFICATION forming part of Letters Patent No. 775,193, dated November 15, 1904.
Application filed October 14, 190].. Serial No. 78,595. (No model.)
Bc it known that I, GEORGE D. ROLLINs, a citizen ot' the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented acertain new and useful Improvement in Metallic Packing, of which the following is a specification.
My invention relates to a certain new and useful improvement in metallic packing, and has for its object to provide means for lubricating the piston-rod and also for cleaning' and wiping the waste oil therefrom.
A further object of my invention is to provide means for securing' the two sections ot' the containing-casing of such packing accurately in alinement, so as to prevent the displacement of these sections relative to each other in any direction.
Vith these ends in view this invention con sists in the details ot' construction and combination of elements hereinafter set t'orth and then specifically designated by the claim.
In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which4 Figure l is asectional view illustrating my improvement; Eig. Q, a section ot' the metallic packing', taken on the line ma' ot' Fig. l; Fig. 3, an interior view of one half of the casing; Eig. a, a cross-sectional view of the casing taken through one of the partitions; Fig. 5, a side elevation of the casing; Fig. 6, a crosssection of a portion of the casing,taken through one of the partitions, showing a moditied form of the plug'.
In carrying out my invention as here embodied, A is the casing, made in two halves A and A2. Ihis casing has a series of annular cavities B formed therein. These cavities are formed to receive the packing-rings C.
D is the piston-rod against which the packing-rings C are held in close contact by means of the spring-rings E, which lie in grooves around the outer circumference of the packing-rings, and these packing-rings being made in segments are thereby held in close contact to the piston-rod D.
F is an annular cavity formed in the casing A, which is adapted to be lilled with absorbent material F, such as felt and the like. The inner circumference ot' this ring ot' felt is adaptedto bear against the piston-rod D. rIhe object of this ring ot' absorbent material is to gather and absorb the oil, so as to keep the piston-rod lubricated, and a further object is to wipe or clean the piston-rod of any dirt or waste oil. IVhile I have only shown one absorbent ring in Fig. l, it is obvious that an absorbent ring can be placed at each end of the casing or at any point intermediate.
The two halves A and A2 ot' the casing are secured together by screws G, and in order to aline the casing, so that the several partitions B ot' the casing will aline properly, I provide screw-threaded plugs H, which arc threaded into screw-threaded holes formed at the intersection of the two halves ot' the casing, the holes being about three-quarters in one halt' and one-quarter in the other half, as shown in Fig. 5, for the purpose of causing the screw-threaded plugs H to remain in one haltl when the two halves are separated. Then the two halves are secured together, the rotundity of the plugs will keep the halves in alinement with one another longitudinally, and the threads upon the plugs will prevent the halves from getting out of alinement laterally, thus relieving thc. screws which secure the halves together from all strain. IVhileI have shown the screw-threaded plugs inserted in the partitions, it is obvious that they may be inserted at any point along the side of the casing oiiering sutiicicnt space for the insertion of the plug.
In Fig. G I have illustrated a modification of the plug in which the screw-threads are dispensed with and a plan plug utilized.
In the d rawiugs I have shown a casing with three ring-sections; but it will be understood that one or more sections may be used, depending altogether upon the amount of packing required.
My improvement is especially adapted to that class of metallic packing' shown and described in United States Patent No. 318,400, granted May 19, 1885, to S. D. Thurston, since it prevents the sections of the casing IOO from being thrown out of alinement when the stuhng-box is tightened, which previous to my invention has been a serious defect in this class of packing, as the slightest displacement of the sections of the casing tend to bind the packing-rings against the interior partitions, thereby preventing the free action of these rings,which is essential to the perfect Working of the device, and my improvement also furnishes means for lubricating the piston-rod D and at the same time removing dirt and waste oil therefrom, which overcomes another serious defect in this class of packing.
Having thus fully described my invention, what I claim as new and useful isl In a metallic packing-ring, a longitudinallydivided ring-casing having a plurality of eq uidistant cavities and a suitable cavity near its top, the said sections having holes at right angles to their sides at their meeting edges, the holes in one section being larger than those of the other section, retaining members seated inthe coinciding holes, packing-rings formed -in segments lying side by side in the equidis- GEORGE D. ROLLINS.
