PIPE BE'ND.
APPLICATION FILED MAR. 18. 1915 Patented July 10, 1917.
CHARLES J. RATEIKE, OF CHICAGO, ILLINOIS, ASSIGNOR T ANSON MARK AND CLAY- TON MARK, COPARTNERS DOING BUSINESS AS MARK MANUFACTURING COMPANY,
OF CHICAGO, ILLINOIS.
PIPE-BEND.
Specification of Letters Patent.
Patented July 10, tart.
Application filed March 18, 1915. Serial No. 15,290.
a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented new and useful Improvements in Pipe-Bends, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is an elevation of a plate blank, of a character suitable for forming into a pipe bend; Figs. 2, 3 and 4 are elevations showing successive steps in the reduction and elongation of a blank or shell, preliminary to shaping it into the desired form; Fig. 5 shows the mechanism and manner of forming the shell or blank into a bend or elbow; Fig. 6 shows the bend or elbow after it has been operated upon by the mechanism shown in Fig. 5, and Fig. 7 shows a formed bend after its closed end has been squared and preliminary to aperturing it.
My invention relates to pipe bends or elbows, and consists in the formation of bends or elbows from plate blanks or cupshaped shells. Fittings constructed in accordance with my invention are of uniform strength and thickness, and are extremely cheap and easy to make. Various features of my invention will also be found to be hereinafter described and claimed.
- Referring to the drawings, the plate shown in Fig. 1 is normally reduced to the shell-like form shown in Fig. 2 by a drawing operation, and may then be reduced by further drawing operations to the forms shown in Figs. 3 and 4:. When it has been reduced so that its open end 2 is of substantially the diameter of one of the ends of the finished bend, it is then placed upon the mandrel 4 of the block 5, so that its end 2 is supported, as is shown in Fig. 5. The block 5 has a curved upper face 6, which corresponds to the curvature which it is desired to have the longer side of the completed bend assume. The die 7 then descends, and its curved face forms the blank into the shape shown in th dotted lines in Fig. 5, and in full lines in Fig. 6. The end?) of the blank ma then be squared, as is shown in Fig. 7, a er which the elbow may be apertured and threaded.
I have found, in carrying out my invention, that the metal does not draw away from the end 2, but remains true at that end, and the metal at the end 3 can readily be trued or squared and then apertured or threaded. It is obvious that completing the form of the blank before aperturing its closed end enables the metal to be worked with much greater freedom than would be the case if the end was apertured before the shaping operation was completed. The number of operations necessary to form elbows has been greatly decreased in carrying out my invention, and the resulting product is much cheaper than heretofore.
The terms and expressions which I have employed herein are used as terms of description and not of limitation, and I have no intention in the use of such terms andexpressions of excluding any equivalent for the features shown and described, but recog nize that various modifications are possible within the scope of the invention claimed.
What I claim is:
1. The process of making pipe bends which consists in shaping a shell of cupshaped form by supporting its bottom end and applying compression to the exterior of the top and bottom of said shell while the interior of the top end is unsupported, and causing one of its sides to bulge outwardly in a direction transvers to the lon itudinal axis of the shell and thereby formmg a fitting of elbow shape, and then aperturing the bulged-out portion.
2. The process of making a pipe bend which consists in taking a plate, forming it into a cup-shaped blank having substantially the diameter of one end of the completed elbow, then swaging the exterior of the blank while the interior of the closed end is unsupported and causing one of its endsto bulge in a direction transverse to the longitudinal axis of the blank, and aperturing the bulged side.
3. The process of making pipe bends, laterally, then truing the end of the bulged which consists in formingda plate blank into portion and aperturmg it. a shell having a c osed en then supporting v its openend and applying compression to CHARLES RATEIKE' the exterior of its closed end while the in- Witnesses: terior of the closed end is unsupported, and B. PETERSON, thereby causing a side of the shell to bulge CLARENCE MARK.
