PIPE ELBOW OR SECTION.
SPECIFICATION forming part of Letters Fatent No. 409,631, dated August 20, 1889.
Application iiledMarch 11,1889. Serial'No. 302,770. (No model.)
To all whom t may concern: l
Be it known that I, CHARLES B. COOPER, of New York,in the county of Newl York and State of New York, haveinvented certain new and useful Improvements in Pipe Elbows or Sections; and l do hereby declare that the fol lowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to whichit appertains to make and use the same, reference being had to the accompanying drawings, and te the letters of reference marked thereon, which form part of this specification.
Myinvention relates to an improvement in pi pe-elbows or curved sections.
The object of the invention is to provide a strong, durable, and cheap curved pipe-sec` tion composed of a suitable numberof transverse sections joined together in an improved manner to form an elbow convex on the back and concave in the throat.
These obj ects are accomplished by, and my invention consists in, certain novel features of construction and combinations of parts, more fully described hereinafter, and particularly pointed out in the claims.
Referring to the accompanying drawings, Figure lis a longitudinal section of the elbow. Fig. 2 is a cross-section on line ma, Fig. l. Fig. 3 is a plan ot a blank. Fig. 4 is an elevation ot the blank bent circular to form a section. Fig. 5 is a plan et a fiat blank used to term an end section ot an elbow.
The curved pipe is composed of a suitable number of transverse sections u., each section being preferably formed from a blank t, cut from sheet metal and tapering from the center to the ends, and of such length that the ends of the blank will overlap when the same is bent circular to form a section et the desired diameter. After the blank is cut the same is bent circular-that is, the ends are brought around to overlap each other to form a hollow section-gradually decreasing in length from the back to the inner side or throat, and the back and throat are curved, as shown, preferably from the same center, so that the outer side c will be convex and the inner side d concave. One of the ends of the blank 'forming a transverse section is depressed or bent in the thickness of the metal,
as shown at e, to form a seat for the other end, so that when these ends are secured t0- gether the outer surface of the section will present no sharp edges or corrugations. These transverse sections are jointed together to form a curved elbow having its outer wall free from transverse corrugations by sinking a sh allow corrugation or depression. f, corresponding with the thickness of the metal used, around one edge of each section of the elbow, (except, of course, one end section,) and this depression or eorrugation,when everlapped by the straight edge of an adjoining section, lies close to its inner wall, making, when joined, a true sectional curved tube.
For elbows to be used for conveying liquids, cbc., the joints of which have to be air-tight, small indentations g, Fig. 2, are made in but not through the shallow corrugation f, encircling one rim of the sections a., and similar corresponding indentations g are formed in the opposite corresponding straight edges of the sections, so that when the sections are placed together the indentations in the corrngations iit in the corresponding indentations in the straight edges, thereby irmly pinning the sections together in addition to the soldering' necessary to make them airtight.
Another feature of this invention consists in forming the end sections 'L' of the elbow curved a portion of their length to conform to the arc of the elbow and straight or tapered the remainder of the length to nt into the full-sized end of a pipe or another elbow, whereby a less number of transverse sections are required. These end sections are formed from blanks such as shown in Fig. 5, having one longitudinal edge of the same contour as the edges et blanks 1) and the other edge approximately straight, with an Outward bulge at the central portion.
The intermediate and end sections are formed from the fiat blanks ot' Figs. 3 and 5, as follows: The blanks are bent into circular form with their ends overlapping, and then placed in the bore et a die internally corresponding in shape with the form of section to be produced. Internal outward pressure is then applied to the blank in the die,which is thereby forced to permanently assume the IOO interior -form of the die. As the end sections are curved a portion of their length, the blanks are provided with the outward bulge mentioned to compensate for the decrease of length in a straight line caused by curving the blank to form the convex portion of the back of the section, and so that the plane of the outer end edge of the section will be at right angles to the longitudinal axis of the elbow.
The hereiirdescribed curved elbow-sections are made as new articles of manufacture', land are so formed that they can be readily joined by the mechanic using them. These sections, when being transported or stored, can be nested, thereby occupying less space and costing less for storage and transportation.
What I claim is-C l. A curved pipeH elbow consisting of a series of transverse sections, each convex on the back and concave at the throat and coinposed of a single blank narrowed toward the ends, which ends overlap and are secured together, one end or edge of Veach section being depressed inwardly the thickness of the metal,
or formed with an annular corrugation, said corrugation and the opposite end of the section being provided with transverse indentations, whereby, when the sections are secured together, the straight edge of one section fits on the corrugation of the next and the indentations intermesh, substantially as described.
2. A curved pipe-elbowconsisting of transi verse sections concave at the throat and convex at the back, each formed of a single blank having its ends secured together, said sections being secured together at their ends, and the two end sections of the elbow at abouthalf their length departed from a curved form and made straight or tapering at the outer ends, for the purpose set forth.
In testimony that I claim the foregoing Vas my own I affix my signature in presence of two Witnesses.
CHARLES B. COOPER.
