APPLIGATION FILED APR. 10, 1904.
MTNEEE NITED STATES Patented August 9, 1904.
SPECIFICATION forming part of Letters Patent No. 766,855, dated August 9, 1904.
Application filed Apri118, 1904:. Serial No. 203,605- (No model.)
To ILZZ whom it ntay concern.-
Be it known that I, IIENRY C. Wnnnnn, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Pipe-Joints, of which the following is a specification.
My invention relates to improvements in pipe-joints of the type for which I have filed application, Serial No. 151,604L, for Letters Patent; and its object is to make these joints more efficient, particularly where the sections composing the joints are for any reason limited in depth.
I have found that the form of pipe-joint described in my above-named application for patent is thoroughly eflicient for all sizes of soil, water, and gas pipe where the necessary depth of hub can be obtained. My present improvement relates to a change in the construction of the sectional joint-forming ring whereby it will make a tight joint even when used with a comparatively slight depth of hub.
In the accompanying drawings I have shown at Figure 1 in longitudinal section a joint in which my present invention is employed; at Fig. 2, a horizontal section on the central line of Fig. l; at Fig. 3, a vertical section of one of the sections of a joint member embodying my present improvement, and at Fig. 4 two members of said joint shown in perspective and slightly separated.
I have found in practice that when the members of a joint-ring are made of plain iron,
which is the material most commonly employed, and where only a relatively small depth for the ring can be allowed-for example, a depth of one inch upon the hub of a ten-inch pipcthat a tight joint isnot always obtained. By my present improvement this difficulty is overcome. I form the sections of my joint-ring with a center or core of iron A and coat this externally, particularly upon those portions which are to come into contact with the hub and spigot of the pipe to be joined, with a covering B, of softer or more compressible metal. This covering may be of a single metal, such as copper or tin or zinc, or of an alloy ofmetals, which alloy shall be compressible as compared with the iron center. By this construction I find thatImay use a ring of relatively slight depth and still be enabled to obtaina tight joint under circumstances where a ring of plain iron would not be tight.
I claim A pipe-joint ring-section of the character described, formed of an iron core and covered upon its outer and inner faces with a relatively compressible metal or combination of metals.
In testimony whereof I have hereunto subscribed my name this 16th day of April, 1904.
