Description
NITED STATES IMPROVEMENT IN JOINTS FOR SHEET-METAL PIPES.
Specification forming part'of Letters Patent No. 159,4 39, dated February 2, 1875; application filed July s, 1873.
To all lwhom it may concern Be it known that l, J osEPH Moonn, of San Francisco, in the county of San Francisco and State of California, have invented an Improved Pipe-Joint for Sheet-Metal Water-Pipes; and I do hereby declare that the following is a full, clear, and exact description and specification of the same, reference being had tothe accompanying drawings, in which- Figure l is a longitudinal section of a portion of pipe, showing the joint; and Fig. 2 is a transverse section.
Similar letters of reference indicate the same parts.
heretofore sheet-iron water-pipes have been connected or jointed either by means of dan ges riveted on each end of the pipe sections and bolted together, or, by means of bell-joints, riveted onto the end of one section, into which the plain end of the other section is inserted and the joint packed with lead in the same manner as is ordinarily done with cast-iron pipes. The latter method, being the cheapest, has been often tried, and, for light water-pressures, is, to a certain extent, successful; but the pressure of the water in the pipe, acting upon the surface of the lead in a line with the length of the pipe, usually expels the lea'd packing from the joint and causes the joint to leak. It was to overcome this defect in this class of pipes that my invention was made, and, after the most thorough course of practical experiment and trial, it is found to be completely successful.
The invention consists in combining, with the different sections or lengths of a sheet-iron water-pipe, a strengthening ring or flange inside ofthe pipe to support the ends of the sections while the lead packing is being tamped in, and to prevent the lead from ruiming through between the ends of said sections; an outside band or tube 5 and a lead packing introduced into the space between the pipe and the outer tubing or band and tamped firmly into said space, as I will proceed to describe by reference to the drawings.
In the latter, A and B are two sections or lengths of sheet-iron water-pipe, which are brought together to form a joint. O is the inside ring, usually made of sheet-iron of sufflcient thickness to withstand the pressure caused by calking or tamping the lead. This ring is fastened to the end of one of the pipesections by rivets which hold it in place, or by other suitable means, and the end of vthe other section is usually shoved over it. The ring is ordinarily from four to five inches wide (longitudinall y ofthe pipe) and one number thicker than the iron of which the pipe is made. E is the outer band or section of tubing, made from three and one-half to live inches wide, usually about two numbers thicker than the iron of which the pipe is made, and about from three-fourths to seven-eighths of an inch larger in internal diameter than the outside of the pipe. D is the lead packing or joint, extending continuously from one side of the band E to the other, and made by pouring the lead into the space between E and A B, and calking or tamping it firmly into said space in the manner usual with cast-iron pipes, as above set forth.
I am aware of the state of the art in the construction of joints for pipes of paper, cement, cast-iron, and other similar materials, and do not claim the same; nor do I claim, broadly, the use of any one of the materials herein referred to for the manufacture of pipejoints; but
What .I claim as new, and desire to secure by Letters Patent, is-
In a sheet-iron waterpipe, the internal strengthening ring or flange O, secured to one of the two'sections of pipe A B, and combined with the opposite section, the oute` band, E, and. the packing D of lend, the latter being tamped lirmly into the space between the parts A, B, and E, so as to afford a continuous lead covering over the joint and to some distance on each side, strengthened oy an iron hoop outside, substantially as and for the purposes set forth.
In witness whereof I have hereunto set my hand and seal.
