No. 796,644. PATENTED AUG. 8,
J. T. & G. W. HAYDEN.
UNION.
APPLICATION FILED AUG. 8, 1904.
UNITED STATES PATENT OFFICE.
JAMES T. HAYDEN AND GEORGE W. HAYDEN, OF OAK PARK, ILLINOIS,
ASSIGNORS TO CRANE COMPANY, OF CHICAGO, ILLINOIS, A CORPORA- TION OF ILLINOIS.
UNION.
Specification of Letters Patent.
Patented Aug. 8, 190 5.
To all whom it may concern:
Beit known that we, JAMES T. HAYDEN and GEORGE W. HAYDEN, citizens of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Unions, of which the following is a specification.
The object of our invention is to provide a union of simple construction which shall be so constructed that the abutting surfaces of the different members of the union shall be composed of different metals which will not corrode together, while the different members of the union will be locked together by a locking member of a different metal from the members of the union. These and such other objects as mayhereinafter appear are attained by the devices illustrated in the accompanying drawings, in which Figure 1 is a longitudinal sectional view of a coupling embodying our invention, and Fig. 2 is a transverse sectional view on the line 2 2 of Fig. 1.
Referring by letter to the accompanying drawings, A B are the head-piece and the tailpiece of the union, respectively. Mounted upon the inner end of the tail-piece B is a brass ring C. It will be noted that the tailpiece B is provided with an inwardly-proj ecting shoulder b and that the brass ring C is rolled onto the inner end of the tail-piece B and inwardly over the annular shoulder b, so as to be securely mounted upon the tail-pieceB. It will also be seen that the brass ring C virtually constitutes a brass gasket, which is interposed between the abutting ends of the headpiece A and tail-piece B. The locking-ringD is of familiar form and engages the head-piece A and tail-piece B in the usual manner.
-With the head-piece A and tail-piece B made of iron, the locking-ring D and the interposed ring or gasket C made of brass or like metal, it will be seen that in this union there are no two abutting surfaces of the same metal. Consequently the corrosion of the union, which commonly occurs when iron is joined to iron, is avoided, while at the same time a coupling constructed as shown and described is much less expensive than an all-brass union.
While we have referred to the different members of the union as being constructed of iron and brass, it will be understood that other metals having like characteristics may be substituted.
We claim 1. A union comprising a head-piece and a tail-piece, one of said members being provided with an inwardly-projecting shoulder and a metal gasket interposed between the abutting ends of said head-piece and tailpiece and secured to position by extending inwardly over said shoulder.
2. A union comprising an iron head-piece and a tail-piece, one of said members being provided at its inner end with an inwardlyprojecting shoulder, and a brass gasket interposed between the abutting ends of said members and permanently secured to position by engagement with said shoulder.
3. A union comprising an iron head-piece and tail-piece, one of said members being provided at its inner end with an inwardly-projecting shoulder, and a brass gasket interposed between the abutting ends of said members and permanently secured in position by being rolled onto said shoulder.
4. A union comprising an iron head-piece and a tail-piece, one of said members being provided with a shoulder which projects in wardly and surrounds the passage-way therethrough, and a brass gasket interposed between the abutting ends of said members and secured to position by being spun or rolled around said shoulder.
53. A composite union comprising a headpiece or a tail-piece of iron or like metal, and a gasket of brass or like metal interposed between the abutting ends of said members, one of said members being provided with a shoulder which extends into the passageway through said member, and said gasket being formed around said shoulder so as to be permanently secured in position.
