Specification-of Letters Patent. Patngntedl J l 11m), 191% Application filed March s, 1915. Serial a... 15,259.
To all whom it may concern:
Be it known that I, CHARLES J. RATEIKE,
a citizen of the United States, residing at Chicago, Cook county, Illinois, have lnvented new and useful Improvements in Pipe- Fittings, of which the following is a specification, reference being bad to the accompanying drawings, in which:
Figure 1 is an elevation of a plate blank; Figs. 2, 3 and 4 are elevations showlng successive steps in the reduction and elongat on of a blank or shell preliminary to shaplng it into the desired fitting;.Fig. 5 shows a blank which has been reduced by an operation preliminary to forming a T; F1g.- 6 1s a bottom view of the form shown 1n Fig. 5; Fig. 7 is an elevation of a formed 'l', and Fig. 8 is a bottom view thereof.
My invention relates to pipe fittings and consists in the formation of fittings from plate blanks or cup-sha ed shells, so that such fittings are 0 uni orm strength and thickness. My invention also relates to the various features which describe and claim.
Referring to the drawings, in which I have shown my invention applied to a T, the plate shown in Fig. 1 may be reduced, by a drawing operation, to the form of a cup-shaped shell, shown In Fig. 2. By subsequent drawing operations the shell is reduced until it is of approximately the diameter desired for one of the arms 2 ofthe finished product, as is shown 1n Fig. 4. The blank is then placed with its arm or end' 2 supported in other suitable d es, which flatten its top surface and bulge Its sldes 3 and 4 to form the other arm or arms of the fitting. Its body ortion 5, as is shown in Figs. 5 and 6, wi l bulge outwardly around the axis of the arm 2 and will assume a mushroom shape. It is then reduced to the form shown in Fi s. 7 and 8, by strlking the blank on its si e, which trues or shapes the projections 3 and 4 to the desired form. The fitting may then be completed by aperturing its ends 3 and 4, and by threading.
I have found that in carrying out my invention I am able t0 construct a pipe fitting in which the metal is maintained of substan- I shall hereinafter tially uniform thickness throughout, and, due to the fact that the ends are not apertured until the form of the fitting is substantially complete, they are of substan tially the same strength as the remainder of the fitting, and need no squaring at the completion of the forming operations. lVIy invention has also enabled me to reduce very greatly the number of operations necessary to form the T, and has accordingly decreased the expense of dies, etc.
The terms and expressions which I have employed herein are used as terms of descrlption and not of limitation, and I have no intention in the use of such terms and expressions of excluding any equivalent for the features shown and described, but recognize that various modifications are possible within the scope of the invention claimed.
What I claim is:
1.The process of making a pipe fitting, which consists in taking a plate, forming it into a on -shaped blank havin substantially the diameter of one arm 0 the completed article, then swaging the exterior of the blank, while its interior is unsupported, and causing its sides to bulge, then shaping the bulging sides to the desired form, and aperturing them.
' 2. A process of making a pipe fitting which consists in taking a shell of cupshaped form, applying compression to the exterior of the top and bottom of said shell,
to cylindrical form, and aperturing the cylindrical portion so formed.
3. The process of making a pipe fitting, which consists in shaping a shell of cupshaped form by supporting the open end of the shell, app ying compression upon the exterior of its closed end while its interior is unsupported, whereby the sides of the shell will bulge outwar until it assumes a mushroom-like form, applying compression to the exterior of the bulged-out portion, to shape such portion to the desired form, and aperturing the end of the portion so shaped.
4. The process of making a pipe fitting,
5 which consists in shaping a cup-shaped shell by externally applied compression, by altering' the diameter of a portion of the shell,
and forming one portion of mushroom-like form and the other portion of substantially the diameter of one arm of the completed 10 fitting, then shaping the mushroom-like portion and aperturing it.
