CHARLES J. WITHERUP, OF PORT-ARTHUR, TEXAS.
PACKING.
Application mea october is@ 1aa. serial ne. 669,513. O
To all vwhom #may-concern.'
Be it' known that I, CHARLES J. VVI'rHEn- Ur` a citizen ofthe United States, residing at Port Arthur, in the county of Jefferson and State of Texas, have .invented certain new and useful Improvements in a Packing,
an annular cork body for engaging-the surface directly, which is be packed, the cork body providing a fini .type packing sur.
face and also means forpreventingwear on the moving part, in view of the fact that the body presents la sbstantially -frictionless surface. v
A lfurther prime object of the invention is to provide an improvedpacking embodv-4 ing a rubberized duck or asbestosfilled container having an annular channel therein for receiving the cork packing body, the
rubberized duckor asbestosffilled container forming means for creating a continuous pressure against the'cork packing. body in 'view of thefact that the said rubberized fabric or asbestos filled container will swell, when 1n use.
the above character, whichA will be durable and efficient in use, one that will be simple and easy t0 manufacture and to installand one which can be placed upon the market at asmall cost. y
With these and other objectsin view, the invention consists in the novel construction, arrangement and formation ofparts, -asiwill be hereinafter lmore specifically described, claimed and illustrated in the laccompanyin drawings, in which drawings:
gure 1 1s a perspective view of the improved packing ring constructed in accordance with, this invention" for Ause on al moving part such as apistom A still further .prime object of the invention is to provide an improved packing of Figure 2 isQa perspective `view of a packing .constructed in accordance with this invention when used for an immovable part.
Figure 3 is a diametricsection through the movable packing ring, and
Figure 4- is a diametric section through the immovable packing ring.
Referring to the drawings in detail, where,-l
in similar reference characters designate corresponding parts throughout-the several views, the letter A generally indicates the movable packing ring and B the immovable packing ring.
The packlng ring A comprises an outer body 5, which. can be formed of a plurality of plies of fabric, such as duck, canvas or the like and the fabric is adapted to be impregnated with rubber or some other simi-- lar material. If so desired the outer body .5' can be formed of asbestos fibre or the like. .Thisbody 5 c'an be folded or otherwise formed to provide an outer'channel/G and the body when folded is substantially U- shaped in cross section and defines upper and lower spaced parallel annular walls 7 and an inner connecting an ula'r wall .8. If; so desired a rubber cushion 9 can be 1nc0rporated in the inner connecting wall 8.1 The channelway 6 is adapted to receive the cork packing ring 10 which forms' the most im- Y portant feature of this invention, as will be hereinafter more fully described.
The immovable packing ring B is' con` 'structed'substantially the. same as the' packing ring A and includesl the outer body 15 which is also formed of a plurality of plies of fabric such as duck or the like impregy natedwith rubber, or `this body 15 can be formed of asbestos. The body '15 is folded or otherwise formed substantially VU-shaped in cross' section.` This provides upper and lower spaced parallel walls 17 and an outer annular'connecting wall 18 which can be provided with a rubber cushion 19 if so desired.' The -channel 16 is arranged to receive tbe solid cork packing ring 20.
Itcan be seen that the two packing rings I A and B- are of substantially the same con struction with the exception that the cork `ring 10 of the packing rintgAifs disposed at the outer periphery of e packing ring,
While the cork -ring 20 is disposed at the inner periphery ofthe ackin ring B.
The use of cork as t e pac g medium fulfills a long-feltv want in the packing art,
in view of the fact that packing rings now on the market under certain trying eondi-- tions will not stand up and permit the leakage of certain fluids. Further certain packlng rings cause great Wear on the moving parts, which result in loss of power.
The cork packing ring forms an ideal packing, as the same provides almost a frictionless surface which will prevent wear but which at the same time provides a snug tit for preventing leakage of all kinds of fluids.
Whether theouter body of the packing is to be made of rubberized fabricor Woven asbestos, depends upon the use to which the packing is to\ be put and it is obvious that when the packing isto be used on devices handling' acids and caustics, that asbestos is best suitable.
While I prefer to provide a body provided with a complete channel for receiving the cork packingring in view of the fact that the body will swell and tightly hold the ring in place, it is tobe understood that the outer body can be eliminated and simply rings of asbestos or rubberized duck sewed or otherwise secured to the opposite faces of the cork.
From the foregoing description, it can`V be seen that I have provided an improved packing of simple and durable construction which will effectively prevent leakage of all kinds of fluids.
Changes in details may be made without dparting from the spirit or the scope of this invention.
lVhat I claim as new is:
A packing of the class described, comprising an annular cork ring rectangular in cross section and an annular channel shaped covering, the web of the channel extending across and fitting closely against one of the cylindrical surfaces of the cork and the legs of the channel extending over and fitting closely against the respective flat faces of the cork ring, said legs terminating flush with` the remaining cylindrical face of said cork ring, said covering consisting of material adapted to swell when in use, and a rubber cushion imbedded in the web of the channel sliep/ed covering and extending concentric to the ring in spaced relation thereto.
In testimony whereof I affix my signature.
CHARLES J. WITHERUP.
