BARREL-HOOP STAPLE.

SPECIFICATION forming part of Letters Patent No. 770,479, dated September 20, 1904.

Applicati n filed January 29, 1903. Serial No. 141,024. (No model.)

To all whom it may concern.-

Be it known that I, FRANKLIN B. SI-IUSTER, a citizen of the United States, and a resident of New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Barrel-Hoop Staples, of which the following is a specification.

My invention relates to staples for wire barrelhoops; and it consists in an elongated construction adapted to embrace and sustain the hoop in any of the positions it may assume on thebarrel.

Wire hoops are driven down on the barrelstaves as far as they will go and are usually secured by means of the ordinary U-shaped staple of about the width of the wire hoop and clenching them on the inside of the barrel. The shrinkage of the barrel-staves soon loosens the hoop, and the only way to tighten it is by pulling out the staples, so as to allow the hoop to drop, and then drive in the staples again. I employ a staple of sufiicient length to cover the amount of shrinkage in the barrel. In other words, the staples are long enough so that the hoop can grip the barrelstaves at some point within the staple, and thus avoid the necessity of drawing it out. In connection with this elongated staple 1 provide retaining-points thereon, so that when the hoop is driven down these points will prevent its working up. The staple is long enough to allow that portion having the projections to spring out when the hoop is driven down.

To enable others to understand my invention, reference is had to the accompanying drawings, in which Figure 1 represents a broken elevation of a barrel, showing a wire hoop at the highest point in the staples. Fig. 2 is a similar view showing a wire hoop at the lowest point in the staples. Fig. 3 is an enlarged detail view of one of the staples. Fig. A is an enlarged broken sectional view of a barrel-stave and staple inserted therein, also section of the wire hoop. Fig. 5 is an enlarged broken sectional View of a barrel-stave, showing the staor partially through.

ple driven through and clenched on the inside. Figs. 6, 7, 8, 9, 10, 11, and 12 are modifications of the staple.

Its construction and operation are as follows:

1 represents the barrel with the staves l, 2 the wire hoop, and 3 the staple. The staples, except those shown at Figs. 11 and 12, are made of wire with corrugations composed of the inner projections 4 and concave portions at in the body portion thereof. The prongs 5 may, if desired, be driven partially through the staves, as shown at Fig. 4, or entirely through and clenched on the inside, as shown at Fig. 5. The manner in which the ends'of the prongs are pointed will determine whether they go entirely through the staves IVith the bevel 5 (shown at Fig. 3) the prongs will tend to curve inward, as shown at Fig. 4.; but with sharp-pointed ends these prongs will pass entirely through and may, as before mentioned, be clenched on the inside of the barrel.

In the modification shown at Fig. 6 the prongs may, if desired, be provided with the retaining-notches 6. At Fig.7' the prongs will tend to curl inward more readily if said prongs are slightly curved inward to start with. At Fig. 8 one of the prongs is left straight, while the other is clenched within the barrel-stave. The purpose of this modified construction is that as the lower prong is firmly anchored in the stave the upper part will readily spring out when the hoop is driven down, as shown at Fig. 9, and when the hoop has reached a position on the barrel where it is tight it will also be under one of the concave portions A of the staple, which will permit the upper end of the staple to spring in again.

At Fig. 10 the upper prong is shortened, with its end resting on the stave.

At Fig. 11 is shown a broken narrow fiat metal strip,from which the staple shown at Fig. 12 is severed. 'The projections or retaining-points 7 are first formed throughout the body portion 8 of the metal strip by breaking down the stock from two sides of the angular openings 9, as shown at Fig. 11. Then the staple is cut off and the ends bent to form the prongs 5 which prongs are given a quarter-turn, so that they will more easily enter the wood.

As before mentioned, the wire hoop is first driven down on the barrel as far as it will go. Then the staple is driven into the staves, so that the hoop will be at the upper portion of the staple, as shown at Fig. 1. Now as the barrel shrinks the hoop is driven down past one or more of the projections formed by the corrugations of the round wire or fiat staples or the retaining-points (shown at Fig. 12) until it is tight on the barrel, and the projections on the staple will efiectually prevent the hoop working back. These staples are made long enough, as before mentioned, to cover the entire range of the hoopsthat is, they are long enough to compass the distance the hoops would be likely to be forced down the barrel. This length will also allow the body portion of the staple to spring out when the hoop is driven by any of the projections and spring back and prevent the hoop working by said projections.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a barrel and a wire hoop, of an elongated staple adapted to embrace said hoop and of sufficient length to permit the hoop being driven down on the barrel without removing the staple, the body of said staple provided with projections to prevent the hoop working back, means for attaching said staple to the barrel, substantially as shown.

2. The combination, with a barrel and a wire hoop, of an elongated staple having a corrugated body portion and means for attaching it to the barrel, said hoop adapted to be vertically adjusted on the barrel without removing the staple, substantially as set forth.

3. The combination, with a barrel and a wire hoop, of an elongated staple adapted to embrace said hoop in all the positions it will assume on the barrel without removing said staple, one or more projections in the body of said staple adapted to retain said hoop in any of its adjusted positions and prevent its working up on said barrel, means for attaching said staple, substantially as described.

4. The combination, with a barrel and a wire hoop, of an elongated staple adapted to embrace said hoop, in all of its adjusted positions without removing said staple from the barrel, one or more projections in the body of said staple adapted to engage with and prevent said hoop working up on said barrel, the body of said staple adapted to spring outward to permit the hoop to pass the projections, substantially as described and for the purpose-set forth.

Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 24th day of January, A. D. 1903.
