oveme'nis 111 do hereby aiec q and Ti (l in 2 Eli is hm honlwl :rml hmat in any -;l0 :mzumm' in u r-lrvulnr form with the l w an the: 'nshlv, bringing the 011 m (1/- her in pcwillrm m lap igh and 0:16 Ti will hr Fem 11 ill 0n cm" u 1 @hmra in swglinn ih z: ring nsthus l :1 I hm he efi ect 0f lgilmr iiw z-ug es a a of the ring); perpen- Hiwlm" will: he lungitmllnal zlXlS of ihe "'nlsequcncc if jhquenily hap- 2021111121 sand lmlvs n1 (lnw'l which would cum. :5: leakzwe if (he lll! m 11 11m indicated in Fig. 6.
Eu vv-uidmg the rings, there must of necessily he alight v: Nations in their internal (liusecl in 21 pips line. necessary to test each Mug; by by l pressure or pneumatic pressure nmlfim defecllve, which adds c011- he cost of production.
those which slderably t0 amelvr and llv is desirable in bring all the ringq of :1 ccllain reqnimd diameter to the same size, in order to adapt them $01 use with the standard sizes of pipe with which they are $0 be usecl.
In order to finish the rings sothat they will be true circles and also to bring them to exact size, they are sub ected to internal pressure or expansion to the required extent by a circular die or tool, so that they will all be brought to a uniform .diameter. To accomplish this result I prefer to employ the means shown in Figs. l and S in which B represents a die or expander formed in segments and provided on its exterior with a horizontal annular groove 0 to receive the bead a of the ring LO avoid bruising it, and provided internally with inclined \vedging surraces 0 which engage a movable tapered wedge block (I. The ring A is placed over the expander l and the wedge t) is pressed into the e.\panucr in any desired way, as by a hydraulic ram indieated at 1), thus expanding the ring until its internal diameter is brought to the desired size. The expansion of the rings to bring them to size, or in other words, to standardize them, may be accomplished by other means. The particular means herein shown and described i'orms no part of the present invention and will be cowred by a subsequent application to be tiled by me herealter.
What 1 claim and desire to secure by Letters latent is l. The herein described process of forming metal rings provided with llared ends and an internal head, which consists in forming a skelp having a central longitudinal bead on one face, and lateral edges inclined toward the beaded face severing said skelp and forming a blank therel'rom having its ends parallel and inclined to the faces thereof, bending the blank into circular form with the b ad on the inner side and welding the ends together, flaring the ends I of the ring so formed and bringing its inclined edges perpendicular to the axis of the ring and expanding the portions of the ring between said flared portions to bring it to a true circle of required diameter. 7
2. The herein described process of forming metal rings having an internal bead, and flared ends, which consists in forming a blank consisting of a fiat plate of a width substantially equal to the length of the desired ring, and a length greater than the periphery thereof, said plate being provided with a longitudinal bead on one face, and having its edges inclined toward its beaded face, forming the blank into a ring with the bead inside and welding the ends together and then flaring the ends of the ring outwardly, and bringing said inclined edges perpendicular to the axis of the rin f.
3. The herein described process of forming metal middle rings for pipe couplings which consists in bending a plate or blank having its edges inclined toward one of its laces, into ring form, welding the ends of the blank together and then bending marginal portions at each end of the ring outwardly to bring the inclined faces thereof perpendicular to the axis of the ring, substantially as described.
ing a wrought metal middle ring for pipe couplings having an internal bead and outwardly flared ends, which consists in forming a blank consisting of a flat plate of wrought metal having 'a longitudinal bead located centrally on one face of the same, bending said blank into the form of a ring, with the bead on the inside, welding the ends of the blank together. and preserving the continuity of the bead during the welding op a'ation. bending the tions of the ring at each end thereof outwardly and expanding the ring to a circle of predetermined diameter whilepreserving the internal bead. to true the ring and standardize it. 5. The herein described process of forming a wrought metal middle ring for pipe couplings, having outwardly flared ends, which consists in forming a blank consisting of a plate of wrought metal, bending sai blank into ring form. and welding the ends 1 together, bending marginal portions only of the ring. at each end of the same outwardly to form packing recesses, and expanding the welded and flared ring to a circle of pre- .delel'i'uined internal diameter, to true the 4 ring and standardize it. l in testimonywhereof I afiix my signalure. in the presence of two witnesses. l l
