Evanston, in the countyof Cook and State of Illinois, have invented `certain new and useful Improvements in Fastening Devices for Shipping-Case Covers, of which the following is the specification.

This invention relates to a device for fastening covers to shipping cases, and has for an object the improvement of the general construction of this class of devices, and the provision of a hardware trimming for pails.

Among the further objects of this invention is to provide a hoop, bail and fastening loops, all secured together, and ready to be instantly applied as a unit to a pail; further to provide a novel manner of securing the tightning and holding wires to the hoop; further to provide a form of fastening device that adapts itself to the nesting of the pails in one another; further to form a beaded hoop in practically continuous formby welding together the meeting ends of the hoop, the bead forming a pressure receiving surface for forcing the hoop into tightened position on the pail; further to position the bent end of the handle bail between the hoop and pail, so that it will be hidden, and as a result of the friction between the bail end and the side of the pail, the bail will stand in such position as it may occupy at any time;fur ther to conceal and render inaccessible, the free end of the wire fastening loops, in such manner that the loop cannot be re` moved, and to prevent the formation of short kinks therein; further to provide a form of fastener that cannot be tampered with without detection; further to provide a completely assembled hardware trimming for pails, that can be quickly applied in position to the pail; further to provide a more simple, economical and efficacious device of the class described, and such further objec-ts, advantages and capabilities as will later more fully appear.

My invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawings, and while I have shown therein a preferred embodiment, I desire the same to be understood as being merely illustrative,

and not as tion.

In the drawings Fig. l is a perspective view of a pail and cover, and showing my improved fastening device in position to fasten 'the cover to the pail.

Fig. 2 isl a vertical transverse section through the upper portion of F ig. l.

F ig. 3 is a perspective View Vof my unitary hardware trimming for pails,v and compris- 1iong1 the hoop, fastening loops and handle limiting the scope of my inven- F ig. 4 is a fragmentary vertical Vsectionaly view showing the manner of securing the free end of the wire loops to the bail.

Fig. 5 is a fragmentary sectional view showing the manner of securing the end of the handle bail to thehoop.

While my invention is particularly adapt ed' and useful in connection with brous pulp pails, and I have so illustrated it, I desire it to be understood that the same is capable of application to other forms of pails, as desired.

Iy improved hardware trimming comprises the hoop l, adapted to be tightly applied to a pail 2, and to the hoop are secured the free ends of the wire fastening loops 3, and the ends of the handle bail 4. After the hoop has been applied to the pail, the upper. ends of the the loops 8 will be caused to overlap over the top of the cover, anda suitable instrument, such as a short bar, or the like, passed betweenthe overlapping ends of the loops, and the loops twisted together as shownin Fig. l.

Referring to Figs. Sand 4, the free ends of the loops 3 areeach secured to the hoop l, by being passed outwardly through an aperture 5 in the hoop, and thence bent upwardly as shown at G, and thence over the top edge of the hoop as indicated at 7, Vand the free end 8 then bent downwardly on the inside of the hoop. Each of the bends referred to are of gradual curvature, and entirely free of any short and abrupt kinks, and when the hoop is pressed into position on the outside of the pail, the inner free end 8 will be secure between the pail and hoop. /Vhen the loops are twisted together, the tension therein will be upwardly against the edge ofthe aperture 5, andthe free end 8 being held between the pail and the hoop willV furnish I perfect resistance to any danger of the loop being pulled away from the hoop. This construction renders it impossible for anyone to surreptitiously remove the fastening loops 3 from the pail while in transit, without such removal being readily discovered. This latter feature I consider of very great importance and broadly new.

The handle bail l is secured by passing each of its free ends inwardly through oppositely positioned apertures 10, and the free end portion 1l .being bentJ within the hoop to stand approximately parallel with that portion of the bail outside ofthe hoop. When the hoop is forced into tight engagement with the pail, the friction between the free end 11 of the bail and the sides of the pail will be sufficient to hold the bail in any position in which it may be left standing. Y

The hoop 1 isl provided on its lower marginal edge with the beaded portion l2, which bead provides a surface to receive pressure for forcing the hoop into tight engagement with the sides of the pail. Such pressure may be applied by the usual rollers used in this class of work, or by any other form of driving means desired. The free ends of the hoop are securely fastened together by welding, as indicated generally at 13, and which weld may be a butt weld or lap weld, electrically or otherwise effected, as desired. This feature of providing beaded hoops, with their free ends welded together, I consider important and new. Or I may if desired secure the ends of the hoop by `rivetnon PrIhe dotted lines in Fig. 3 show-the fastening loops in overlapped position prior to their being twisted together as described above.` i

It will thus be seen that amongst othei' features of importance, I have provided a hardware trimming of unitary structure comprising a hoop, wire fastening loops, and a handle bail, completely assembled together in the shop prior to their being applied to the pail.. By my invention not only is the efficiency of cover fastening devices greatly' increased and. perfected, but the manufacturing of the same can be much more rapidly accomplished, in the case of the present invention it being possible for one man to apply fifteen hundred or more of these unitary fastening devices in a nine hour day, and which application of these fastening devices is the last opei'atioii performed upon the pail.

It is also to be noted that my improved form of fastenin@r device ada ts itself admirably tothe nesting together of the pails,

`it only being necessary in this connection to bend the wires downwardly within the inside ofthe pail, and seat the neXt pail therei i to the hoop Y v Having now described my invention,

I claim:

1. In a device of the class described, a hoop, a plurality of wire loops adapted to be twisted together over the outside of a pail cover, the free ends of said loops being each passed outwardly through an aperture in the hoop, then bent upwardly and inwardly, and the free end portion of the loop being bent downwardly along the inside of the hoop.

2. In a unitary hardware trimming for pails, comprising a hoop adapted to be driven into tight engagement with the sides of a pail, a plurality of wire loops passing through apertures in said hoop and adapted to be twisted together over a pail cover, and a handle bail passing through apertures in said hoop, said hoop, loops, and bail, all formed in a unitary structure prior to application to the pail.

3. In a fastenerffor a pail, a hoop beaded to provide an annular shoulder to receive pressure for driving Vthe hoop into tightened position on said pail, and means secured to said hoop bearing against the sides of the pail to prevent said hoop from downward movement, said beaded hoop having its ends welded together.
