MAXING TUBULAR FITTINGS AND THE LIKE.
Application llled February 8, 1927. 'Serial In certain previous Patents Nos. 1,518,599, dated December 9, 1924; 1,586,690 and 1,586,691, dated June 1, 1926, I have described v methods of welding segments which are thicker at one point than at another, and the production in this way of valve casings, Ts and other tubular parts.
My present invention is directed to the etlicient production of the same and similar articles, with certain improvements in the process and products.

My invention has probably its greatest section and an cause of the cost of making them by known methods and with the required accuracy and when the latter is folded over,
strength. This comparative value is also considerable in making Ts, Ls and other angular fittings. And for straight fittings like that of Fig. 28 and even for simple pieces of tubing, it is valuable in cases Where reinforced ends are desired.
' According to Fig. 1, the valve casing is a T-shape with a branch 1 and end portions 2 which are threaded or otherwise connected to pipes 3. The end of the branch 1 is reinforced by folding it over double as at 4;y and is further reinforced by a ring 5 'embraced between the two thicknesses of metal. One of the ends 2 is similarlyreinforced by a folded over portion 6 embracing a separate ring 7. The opposite end 2 is similarl folded over at 8 and further reinforced y embracing the ring-shaped end 9 of a diaphragm designed to form or to carry the usual Valve seat. This diaphragm has a closed inner end 10` and a semi-circular intermediate portion 1l (sce Fig. 3), in the upper portion of which the opening 12 is provided for the valve.
A similar casingmay be made without the separate reinforcing ringsff.. and 7. Figs. 4 to 9 show how such a casing can be produced; and it is obvious how it can be modified to include the separate reinforcing rings. The complete casing is made up in two halves with their edges in the plane indicated by the dot-ted line A-A *in Figs. 1 and 3 and the parts are then brought together and welded along the several joints lyingin such plane. It will be observed that this is the plane of the axes of the two parts of the litt-ing which lie at an angle with each other. Starting with a flat blank of approximately T-shape, the edges are folded over to make a double thickness and the blank' drawn or bent up to segmental shape, providingl extra thicknesses of the original sheet metal at 13, 14 and 15, Fig 4.
tubular piece 16 is inserted in the posi-l `ficientlylarge to permit the passage of the tubular piece 16.
The latter may be a piece of ordinary tubing or it may be formed. in the manner sho n in Fig. 5 of two segments 17 welded togevther on the lines 18. Or one of l the parts 17 while flat may be assembled on value 1n connection with valve casings beeach of the flat blanks for the vouter casing and its end caught under the thiclmess 15 the two parts 17 being then weldedtogether when the segments of the outer casing are welded together. The parts being welded as described are thereafter re-shaped as shown in Figs. 6 to 9.
The inner portion of the tube 16 is swaged to the substantially semi-circular cross-section 19, leavingthe ring 2O at the end caught between the parts 2 and '15 of the shell. The end of the part 19 is then swaged or bent inward to form an end portion 21 (Fig. 8), with an opening 22 which may be subsequently closed by a piece inserted and arc welded or otherwise united. The next operation consists in punching a hole 24 in the top of the;
Fig. 1() illustrates a slight modification in `which the reinforcing rings in the ends are made f different thicknesses. l end the inserted ring 25 is of the Aleast thickness, being `associated with the ring 20 forming art of the diaphragm structure. In the leftian'd end 2 the separate reinforcing ring 26 is thickest to match the double thickness at the right-hand end. And the ring 27 of the branch 1 is of intermediate thickness corresponding to its smaller diameter.
Fi 11 shows' a variation in which the inserte piece 19 for forming the diaphragm is folded over at its outer edge toprovidean outside thickness 28 which encloses the single thick end portion 29 of the shell.
According to Fig. 12 the right-hand branch 2 is folded over to a very considerable length (beforefbending'up to segmental shape) to form the greater portion 30 of the diaphragm, the latter being completed by an end piece 31 which is welded to the line 32. i
According to Fig. 13, the end 2 is folded over for a short length to form a simple ring 33. And the diaphragm memberv 34 for its entire length is a separate piece welded to the iiange 33 as indicated at 35.
Fig. 14 illustrates a segment where an additional reinforcement at the flange has been obtained by a double fold in the blank as in-v dicated at 41 and 42. The same idea may be applied to the designsshown in the other figures; and may be extended to form three or more folds. l
' Figs. 15 to 18 s ow the process of shaping the segment shown in Fig. 12. The blank 36 has the edge of its branchportion bent over to form a fold 37 and its left-hand end similarly bent over to form a narrow fold 38.- T he opposite end is folded over a considerable lengtln to provide a portion In the rightthe diameter of part 30 along the united at the same 39 from which' the diaphragm is to be shaped. The parts may then be drawn up to the position of Fig. 18 with the folds 37 and 38 forming parallel `reinforcements of thelr respective en'ds. .After welding the two segments theppart 4() may be swaged as shown at 30 in Fig. 12^ and the'piece 31 subsequently welded thereto. By using a number of preliminary operations the completed segment shown in Fig.
12`could be formed up with the pieces 31 integral with 30 but for economy in operation we prefer to weld 31 to 30.
Fig. 19 illustrates a slight modification of the samey construction. An
troduced between the two thicknesses of metal at the branch 1 and a similar insert at 'the left-hand end 2. At the right-hand'end there is an insert comprising -a ring portion 45 and an extension 45a between the bottom of the casing and the inner part of the diaphragm member 43. This figure shows the ends of the fittings internally threaded. 4 It will be understood'tbhat this and various other usual or suitable fastening means may be applied to the several fittings illustrated herein. lNhere there is an extra thickness of metal within the shell as in this case, there is an advantage in that a fitting of a given size may be adapted to larger or smaller pipes by making the threads on a larger or smaller dia-meter. This is a substantial economy compared with the making of separate dies for fittings the pipe. 4. Fig. 20 shows the invention applied to the foldingover of the metal double at the ends but in transverse direction instead of ,axial as in the previous fittings. Here there are comparatively long branches-and ends 46, 47 and v.48. The branch 46 is reinforced by 'bending the metal first-Outward to form the phragm member 57. c,
. .4 This valve is made on the same principle as'the others previously described, of segments welded together on the plane of `the tivo axes at an angle with each other. The diaphragm member can be completed or par-V tially completed before assembling itwith the segments,` or can be made in segments time as the segments of the outershell, as above described.l
Fig. 21`illustrates a segment which can be best made by forging; The branch 58 is without end reinforcement. The opposite ends 59 are identical and are stiffened by portions 60 folded back to substantially parallel position of metal. The diaphragm member 62 is ininsert 44 1s in-.
with spaces 61 between the two foldsfor each small variation in t tegral with the shell. It will be observed vide an inner fold that this segment presents edges to be weldedG shell and embraci which are of substantially or approximately shell a reinforcin 83 spaced apart from the ng between itself and the g ring 84. Or the reinforce same thickness throughout, this effect belng ring may be omitted, bringing the two ing secured at the reinforced ends by spacing parts 82 and 83 into dlr them apart with the ad the folds apart as illustrated.
Such a segment presents an advantage in Welding by the method described in m 29 is former patents, in that the path for the wel along ing current presents about the same resistin F1 ance at all pointsin the length of the joint. bent 1 This is a desirable condition and should be s ape so as secured to as great an extent as possible. fold Fig. 22 illustrates the invention applied to The the making of a gate valve. The .upper may be branch 63 is bent over to provide a transplain and'it wi verse flange 64 for the passage of fastenin vention ma bolts and an outer flange 65 in the axial d1- ends of th e'ct contact, or spacing vantages stated above.

The edges of the blank have been nward before stamping to segmental provide the ends 85 with a second 86 in direct Contact with the outer shell. ge 87 on which the cover 88 is screwed y reinforced or maybe left ll be understood that the iny in general be applied to all the e tubular products referred to or rection. Each of the ends 66 is bent outward only to one or more ends as circumstances and inward to' provide parallel folds 67 and maly n 68 in the transverse direct-ion, and 69 and 70 most of the i in theaxial direction. The'spacing of these have illustrated th portions apart from each other not only tion.
It will be u facilitates welding as above described, but structures illustra gures of the drawing, I e product after complenderstood for each ofthe ted that it is made in a avoids the excessive strain on the metal which manner similar to those illustrated in conis'involved in bending it double directly upon nection with Figs. 4 to 9 itself. l by bending the A reinforcing ring 71 is inserted between stampin the parts 66 and 70, and the parts 70 and 71 with dou le-thick ends and are extended inward to form a. seat at one of such segments; with or side\of the valve.
