Patented Oct. 13, 1936 PATENTOFFICE RIVETLESS noor Jom'r HarryC. Brainard, Detroit, Mich.

Application September 10, 1935, Serial No. 39,960 i.

4 Claims.

This invention relates to an improvement in joints for the hoops and reinforcing means of barrels and the like, and more particularly to a rivetless hoop joint and the method of making the same.

The main object of the invention is to provide a rivetless hoop joint that is cheap to manufacture, that is strong, that will not cut the hands of workmen who handle containers provided with reinforcing hoops and bands so joined together. Another object of the invention is to provide a method of making a rivetless hoop joint.

These and other objects and features of the invention will be understood from the following description taken with the accompanying drawing, wherein;

Fig. 1 shows a perspective view of a butter tub provided with hoops having joints embodying the present invention;

Fig. 2 is an enlarged vertical view of one end portion of a hoop as it appears preparatory to being joined to another end;

Fig. 3 is an enlarged vertical view showing the complementary end portion of a hoop preparatory to being joined to the end portion shown in Fig. 2;

Fig. 4 is an enlarged vertical view of two ends of a hoop as joined together by my invention;

Fig. 5 is a sectional view taken on line 5-5 of Fig. 2; and

Fig. 6 is a sectional view taken on line 6-6 of Fig. 4.

In the art of making butter tubs, barrels and the like, a reinforcing band or hoop which may or may not be corrugated, but which is either provided with an annular flange or an annular bead along its lower edges has become well known and is in common use. Of course, the flange or bead may be provided on the upper edge. My invention applies to this beaded or flanged type of hoop.

In Fig. 1 of the drawing, I have shown a butter tub lll, provided with a series of beaded hoops H, for securing the barrel stays l2, in the usual manner. The ends of the hoops are shown as joined together with my rivetless hoop joint.

The band portion 13, of each hoop is provided with an annular bead l4, along its lower edges in the customary manner, although any type of flange may be used in lieu thereof.

My invention consists in providing a means for uniting the ends of such hoops without the use of rivets, screws, bolts or the like.

Near the end of each beaded or flanged hoop, I cut away one or more portions of the bead, or of the flange, as the case may be. For instance, in the case of the bead shown, I prefer to cut away two portions thereof at each end, the cutaway portions or seats being designated by the numerals [5,16, I1, and i8, thus leaving one or more projecting portions on each hoop, such as those designated by the numerals I9, 20, 2|, and 22. These portions are cut in such manner that the cutaway portion or seat I5 of one bead will receive projecting portion 2| of the other bead and cutaway portion or seat ll of the latter will receive projecting portion IQ of the former. Similarly cutaway seat portion ill of the one bead will receive projecting portion 20 of the other and cutaway or seat portion l6 of the latter will receive projecting portion 22 of the former when the ends are placed one over the other in joining them.

In the preferred embodiment of my invention, I provide a locking means as hereafter described. On one end of the hoop ll, above the cutaway portion or portions of the bead I4, I cut out a portion of the band 13, making a recess 23 in the top thereof.

The end of the hoop that has the recess 23, is then placed over the other end of the hoop and the respective projections and cutaway portions of the bead are interfitted.

I then perform a forming operation that bends the portion of the hoop that is underneath the recessed portion over the latter, as shown in Fig. 4, designated by numeral 24. This not only prevents the projecting portions of the bead from coming out of alignment with each other, but also serves to aid the interlocking beads in preventing telescopic movement of the respective ends of the hoop.

It is headily seen that the projecting portions of the beads act as lugs which engage complementary projecting bead portions or lugs which prevent separation of the hoop ends so long as the bead portions engage each other. It is also seen that the portion 24 of the band that is bent over the recessed portion 23 holds the bead portions inalignment and forms abutment shoulders 25 and 26, which respectively engage the shoulders 23a and 23b ofthe recess 23; said portion 24 and said shoulders 25 and 26 thus aid in preventing longitudinal movement of one hoop end with respect to the other.

This locking means may also be accomplished in other ways. For instance, it is not necesinterposed projecting portions are provided near each end for seating into the seats adjacent each opposite end of the band when the ends of the band are overlapped.

2. In a rivetless hoop the combination of a metal hoop band, a flange projecting laterally from one edge of said band, spaced seats in said flange adjacent both ends of the band providing interposed projecting portions near each end of the band for seating into the seats adjacent each opposite end of the band when the ends of the band are overlapped, and means for keeping said projecting portions interlocked in their respective seats.

3. In a rivetless hoop the combination of a metal hoop band, a laterally projecting bead formed by curling up one edge of the band, spaced out out portions in said bead to provide spaced seats and interposed seat fitting projections adjacent both ends of the band for mutual interlocking engagement when the ends of the band are, overlapped.

4.111 a rivetless hoop the combination of a metal hoop .band, a laterally projecting bead formed by curling up one edge of the band,

spaced out out, portions in said bead to provide spaced seats and interposed seat fitting projections adjacent both ends of the band for mutual interlocking engagement when the ends of the band are overlapped and a recess in the other edge of said band opposite said bead for receiving a bent over portion of the overlapped end of the band to keep the interlocking bead portions interlocked and to aid them in preventing telescopic movement of the respective ends of the hoop band.
