1'0 all whomrit may concern:

Be 1t known that I, Gnonen HENRY VVi-Irrn, citizeiyof the United States,- resid ing at Oil City in the'county of Venango and State of ennsylvania, have invented certain new and useful Improvements in- Blanks for the Manufacture of Middle Rings for Pipe-Couplings, & c;.; and Iv do hereby declare the following .to be a full, clear, and

exact description otthe invention, such as will enable others skilled in the art to which ,it appertains toniake and use the same.

- My invention consists in the novel features herelnafter described reference being had to the accompanylng drawlng which illustrates one form in which I have contemplated elnbodying iny invention and said invention is fully disclosed in the following description and claim.

" metal bar or blank 'adapted especially for The object of nay-Invention is to provide a the manufacture of middle rings for rubber packed-pipe couplings: These middle rings are proyidediwitha substantially central in- "s 'kelp, which is formed ofwrought metal as ternally projecting centering stop and the vend portions.of the ring are provided with packing. engaging portions which are usually bent or fiaredoutwardly to form an annular packing recess at each end of the ring.

My present invention consistsof a bar 01' wrought iron or 'steel,- and is preferably "formed by rolling. length-than breadth and of greater breadth The bar is of greater than thickness, and is provided .on one face with acentral longitudinally disposed bead,

'extendingthroughout thelength of the bar v or blank, or it maybe interrupted at inter- F 'v.als.' I prefer to have the bead extend throughout the lengthof the bar or blank. The lateral edges of the bar or blank. arc

' preferably oppositely beveled or inclined in such'a. manner that the beveled edges if prod'uced would intersect on the same side of the bar 'onwhich the head is located, or in other words the beveled edges converge toward the beaded face.

embodying my invention. Fig. 2 is a transside elevation of ablank or bar-suitable for lap-welding. "Fig. 4 is an. elevation ofthe fblanl; or bar shown in bent into ring fol-1n preparatory to welding. Figs. 5 and (S are sectional views of rings produced from my improved bar or blank. Fig. 7 is a see tional view of a modified form o t' bar or blank.

In Fig. 1 I have shown in perspectives piece of the skelp or bar as it comes from the rolls. A represents the body of the bar a the longitudinal bead, and a a the bev;

eled lateral edges converging toward the 1 beaded face, as clearlyshownin cross section in Fig. 2. \Vhen thering is to be inade by la pnvelding the bar is cut in suitable lengths by incisions inclined to the faces of the bar and parallel to each other so that the blank is provided with parallel inclined endffaces a a as clearly shown in Fig. 3. If the rings, are to be butt-welded, however, the ends of the blanks may be perpendicular to the faces as will be obvious.

Ill

Fig. 3 shows a completeblank suitable for in ends of the ring formed by the beveled edges of the blank, or bar. Fig. 6 shows in section a ring which has had its end port1ons flared outwardly to br ng the beveled portions perpendicular to the longitudinal axis of the ring. M

Fig. 7 is a sectionalview of a modified Form of: blank or bar indicated at A, having the central head a". and having the latoral edges perpendicular to the broad faces,

ilistea'd of beveled. The process of treating I this blankis disclosed in my application Serial No. 295,885), filed Jan. 13, 1906.

What I claim and desire to secure by Let-v ters Patent is:- 'lhe herein described blank for a middle ring for pipe couplings. consisting of a bar of wrought inetalhaving a longitudinally disposedbead substantially centrally located on one face and hiring its lateraledges bevcled oppositely and converging-toward said beaded face.

In testimony whereof I aiiix in the presence of two witnesses.
