T 0 all whom it may concern:

Be it known that I, WiLLIAM Ross, a subject of the King of Great Britain and Ireland, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Hoop-Couplings, of which the following is a full, clear, and exact description,

the rod are drawn toward each other, the

center line of the rod will always be in a medial plane.

Another object of my invention is to have such a coupling exert a contracting force on the staves immediately thereunder, which is uniform with the force exerted by the hoop rod upon the other stave members.

A further object of the present invention is to produce a coupling that can be forged readily and economically from a metallic stri F hr an illustration of one of the forms my invention may take,'referenc e is to be had to the accompanying drawings, in which: Figure 1 is a view of a wooden tank with couplings shown in place on the tank; Fig. 2 is an enlarged view of a section of the edge of such a tank as is shown in Fig. 1; Fig. 3 is a side elevation of the forged member of the coupling, while Fig. 4 is a section taken along the line 44'of Fig. 3. 7

Referring to Fig. 2, 4 is. a metal strip of rectilinear cross section with the looped shoulders bent in it, each to form anchors or terminals for the threaded end 9 of the hoop rod 11. Holes of the proper diameter are formed in both shoulders. By having the shoulders for ed in a U or looped form as shown at 8, 2, the force exerted on the faces of the shoulders when the nut 12 is tightened on the rod 11 is distributed through both sides of the coupling and is reacted along the face of the coupling at 13 and 14. The side of the shoulder 3 which takes the pull of the rod 11 is reinforced by the outward side of the loop 10 which is also braced by the outwardly extending portion 21. If any bending takes place at the point 16 of the strip, a partial Wedging action likewise takes place between the rod and coupling at the point 15, which will also facilitate in distributing the force exerted by the rod upon the coupling and prevent the shoulder from further bending at point 16.

By having the outwardly extending portion 21 of the coupling flared and tapered as shown at 17 and 18,Fig. 3, greater contact surface with the wood is provided and any tendency the edge 20 may have to mar the surface of the tank is greatly decreased.

. From the foregoing description it can be seen that I have invented 'a coupling which can be forged economically from one piece of metal. Also by forging looped or U shaped shoulders in a metal strip I can produce acoupling with a minimum weight of metal that will have the requisite strength of a stave tightener. Likewise the center line of the hoop rod is always maintained in a medial plane.

Having thus described my invention, I claim:

1. The combination with a circular wall and a hoop therefor, of a coupling compris ing a forged -metallic member, U-shaped shoulders bent therein, with opposing faces and holes in said shoulders through which the threaded ends of the hoop pass, said hoop ends being engaged by nuts which bear upon said shoulder faces.

2. The combination with a circular wall, of a yieldable hoop comprising a metallic strip doubled on itself in two regions to pro vide outwardly projecting shoulders, a hoop having its ends movably attached to said shoulders and portions on said coupling beyond said shoulders engaging said wall and adapted to receive the strain when pull is exerted on said shoulder by the hoop and to distribute it along the end portion of the coupling in contact with the wall.

3. The combination with a circular staved wall anda hoop therefor, of a coupling comprising a forged metallic member having looped shoulders bent therein, and tapered and flared extensions from said shoulder loops at the ends of the coupling.

4. The combination with a circular staved wall and a hoop therefor, of an arcuate metallic hoop coupling with outwardly projecting U-shaped portions, providing shoulders, the faces of which are normal to the circular staved wall and transverse of the strip.

5. The combination with a circular wall and a hoop therefor, of an arcuate coupling,

said coupling having looped shoulders formed therein and proportioned to yield slightly and thereby distribute the force along the arcuate portion of the coupling in contact with the circular wall.

6. A metallic hoop coupling, comprising a one-piece strip of arcuate form, providing a stave bearing portion on one face, and having U-shaped portions bent up from said face to form shoulders, whereby gaps are formed in said bearing face longitudinally thereof.

7. The combination with a circular staved wall and a hoop therefor lying in a single plane, of a coupling comprising a forged metallic strip, U-shaped shoulders bent therein having opposing faces and holes located in said shoulders in the plane of the hoop, the terminals of said hoop extending through said holes.

8. In a forged hoop coupling, a face por-' tion adapted to contact with a stave wall,

U-shaped portions projecting outwardly therefrom providing shoulders with opposing faces, said faces beingnormal to the stave contact portion of the coupling whereby a gap is formed in said portion. 7 7

9. In an arcuate metallic hoop coupling,

U-shaped shoulders forged therein and providing gaps in the face of said coupling and arcua'te portions extending therefrom and adapted to seat on a stave wall.

, 10. In an arcuate metallic hoop coupling, looped shoulders forged therein and tapered and flared portions on the ends of said couplin and extending outwardly from said shoiilders.

11. A metallic hoop coupling, comprised of a one-piece forged metallic strip, said strip having outwardly projecting U-shaped portions forged therein and tapered and flared extensions from said shoulders on the sides of said shoulders adjacent the ends of the coupling respectively.

12. An arcuate metallic hoop coupling, comprising a one-piece forging, outwardly projecting U-shaped shoulders bent therein, and registering holes formed in the side face of said shoulders.

13. An arcuate metallic hoop coupling, comprising a one-piece forging, outwardly projecting U-shaped shoulders bent therein, holes formed in said'shoulders, and arcuate portions tapered and flared outwardly from said shoulders.

14. An arcuate metallic hoop coupling, comprising a one-piece forging, outwardly projecting U-shaped shoulders with opposing faces normal to the stave contact portion of the coupling, holes formed in said shoulders, and arcuate portions tapered and flared outwardlyfrom said shoulders.

15. An arcuate metallic coupling, comprising a one-piece forging, outwardly projecting U-shaped shoulders with opposing faces, an intermediate arcuate strip between the shoulders, and arcuate portions adjacent to and extending from said shoulders, said portions being tapered and flared toward the ends of the same.

In testimony whereof, I hereunto afix my signature.
