ROBERT \V. STEYVART, OF MOUNT VIOTORY, OHIO.

BARREL-HOOP.

SPECIFICATION forming part of Letters Patent No. 392,473. dated November 6. 1888. Application filed October 20, 1887. Serial No. 252,988. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT W. STEWART, a citizen ofUnitcd States, and a resident of Mount Victory, in the county of Hardin and State of Ohio, have invented anew and useful Improvement in Barrel-Hoops, of which the following is a specification.

My invention is an improvement in barrelhoops, or in the means of locking the hoops together.

Figure 1 is a perspective of part of a barrel, showing my hoop; Fig. 2, a perspective of my locking device; Fig. 3, a strip out preparatory to making a loop; and Fig. 4 is a perspective of my strip.

A is the hoop. B G are holes in the same for the insertion of the loop.

I) is the strip or loop for locking the ends of the hoop together.

E is the joint of the hoop; F G, the overlapping ends of the strip, that fold on the inside of-the hoop; II I, locking-notches on the ends of the strip, that lap inside.

The object of my invention is to provide a hoop that can be made by machinery, readily put together securely, economically, and safely. To this end I cut the ends of my hoop oil square at the proper length just to form the size of hoop desired, and a short distance from the ends I punch the holes 13 O. I then bend the ends of a strip of sheet metal or other suitable material in the shape shown in Fig. 2 at F and G and pass them through the holes and bend them close against the inside of the hoop. Instead of the plain ends F G, I may, when preferred, notch the ends, as shown at H I, so as to form a look when bent over on each other. WVhen the hoop is placed on the barrel and driven down, the pressure of the hoop upon the side of the barrel presses so tightly upon the inside ends of the loop that there is no possibility of the ends escaping or unlocking. So firmly do they hold, that the hoop can be broken by driving before the loop will yield at all.

By the use of my square-ended hoop about thirty per cent. of material is saved over the old hoop, and by the use of my locking-loop the hoop, after once made, is always ready to go on the barrel, and can be used over and over.

This form of hoop allows me to finish up the hoop completely by machinery, and forms a hoop that is never liable to unlock or get out of order.

WVhat I claim as my invention is lhe hoop A, having the holes B O, and the stri p D, passing loosely through holes B O and bent back upon the inner side of the hoop, adapting it to the bulging beveled side of the barrel and becoming tighter the farther it is driven on the barrel, substantially as shown and described.
