GREASE RETAINER WITH UNITARY DIAPHRXGMS AND SUPPORTS Filed-Nov. e, 1936" 65- I 77 GHZ JOJEPH B. V/C TOR //VVNTOFI Patented July 25, 1939 UNITED srATss "PATENT "OFFICE GREASE RETAINER WITH UNITARY BIA- PHRAGMS AND SUPPORTS.
Application November-ii, .1936, Serial No. 109,499 20laims. (01. 288-3) i This invention relates to improved grease retainers or oil seals, and has, for its principal object, the provision of such devices which include unitary diaphragms and supports therefor.
One of the-important objects of this invention is to provide a grease retainer or oil seal which can be made in various types and sizes, and which, at the same time, can include a standard type of diaphragm or packing element, which packing element is molded to a metallic support, which metallic support can be readily incorporated into a construction which includes an outer retaining shell adapted to -be driven or otherwise fitted into a surrounding housing and which retaining shell may be of desired size and dimension without disturbing. the size and dimension of the diaphragm'and its support.
Another and further object of the invention is to provide a double sealing structure comprising a pair of opposed molded diaphragms on standard supports which can then be incorporated into a. containing and retaining shell, which shell or shells may be of difierent sizes and construction so as to be readily changed to meet various conditions met with particularly in the automotive industry. r 1
Other and further important objects of the invention will be apparent from the disclosures in the accompanying drawing and following specification. Y 1
The invention, in a preferred form, is shown in the drawing and hereinafter more fully described.
In the drawing:
Figure 1 is a sectional view illustrating a pair of diaphragms on standard types of supports with a special double housing or shell thereover.
Figure 2 shows a modified form of the structure of Figure 1. v
As shown in the drawingf In Figures 1 and 2, double seal constructions are provided for heavy duty, the diaphragms 58 of Figure 1 being molded onto supports 60 bent to shape as shown, which supports are then positiorred in a shell 62 m opposed relationship to ,each other and preferably with a packing washer or other similar sealing element 64 therebetween. An outer washer 66 is" then incorporated into the structure, after which the edge 68 of the shell 62 is bent downwardly into sealing relationship with the whole, thereby forming a unitary sealing structure adapted to be inserted into'a surrounding housing.
the edges of the supports 12 in a slightly diflerent manner, and a slightly diiierent shell 14 is pro- .vided open at both ends, the closures being formed by flat washers 16 held in position by the spun-down edges 18 of the shell 14.
In all of these seals, it will be noted that a standardized form of diaphragm and metal support is employed, the same being adapted for use with various types and sizes of surrounding shells with either little or no change in the metallic support for the diaphragm. Obviously, if a shell of greater diameter is desired the supporting washer for the diaphragm can be made correspondingly larger or can be shaped somewhat differently to meetthis requirement.
- I am aware that many changes may be made and numerous details of construction varied throughout a widerangewithout departing from the principles of this invention, and I, therefore,
I do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.
I claim as my invention:
"1. composite fluid seal, including. an outer meta shell, a pair of packing elements positioned in the shell, each packing element having a flat radially extending portion, and a metallic supporting element for each packing element to-' gether with a molded joint between the radially extending portion of each packing and its supporting element-said supporting elements each comprising a cup-shaped shell with anoifset inner flange for contact with the packing element, and means for mounting said shells in fluid-tight relationship in the outer shell, said means in-' binding a packing washer interposed between the abutting faces of the said shells, and a spun-over edge on the outer shell for retaining the inner shells and said packing washer in desired relationship.
2. A composite -"fluid seal, including an outer metal shell, a pair of packing elements positioned in'jthe shell, each packing element having a flat radially extending portion, and -a metallic supporting element for each packlng'element to-' I gether with a molded joint between the radially extending portion of eaclf packing and its supporting element, said supporting elements each comprising a cup-shaped shell, and means for mounting said shells in fluid-tight relationship in the outer shell, said means including a packing 'washer interposed between the abutting faces of the said shells, and a spun-over edge on the outer shell for retaining the inner shells and said packing washer in desired relationship, and a flat A outer washer interposed beneath the spun-over In Figure 2, the diaphragms 10 are molded onto edge of the outer shell and the periphery of the adjacent inner shell.
