oLosURE FASTENER.

Application filed October 30, 1926. `Serial No. 145,295. v

My present invention relates to improvements in closure fasteners which wnile adapted for use with closures for various receptacles and in different ways, it is espe-Y ciaily designed for use in fastening andsealing the tcp of a milk can, to prevent nnauthorized access to the contents of the can, and to indicate or show that the can has been tampered with. r)The invention contemplates the use of a seal in combination with the closure fastener which seal may be broken at the proper time, and discarded, but the closure fastener itself is adapted for re pcated use. rlhe closure fastener is of the shackle type, and in this instance is designed to fasten the top of the milk can to one of the handles of the can, and for this purpose a specially construct-ed shackle or double end hook is provided. The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth and claimed.

ln the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to the best mode I have so far devised for the practical application of the principles of my invention.

Figure 1 is a sectional view of part of a milk can and top, with the closure fastener of my invention in use thereon;

Fig. 2 is an enlarged perspective View of the fastener detached and in locked and sea-led position;

Fig. 3 is a` longitudinal sectional view showing the fastener and with the released latch in open position as shown by dotted lines; and

Fig. 4 is a detail of the rack device.

In the preferred form of my invention, as illustrated in the drawings, the device is adapted for use with a milk can as indicated by the numeral 1 having a neck 2 and an outwardly flaring neck ring 3. The can top or closure is indicated as 4 and is provided with an annular bead 5 and bead wire 6, and a slot 7 is provided in the can top just below the bead wire for attachment of one end of the closure fastener. The other end of the closure fastener is attached to one of the handles as 8, as shown in Fig. 1. The closure is provided with a hook 9 at one end for engaging the can top, and at the other end another hook 10 is provided for engaging around the handle 8 for the purpose of fastening and retaining the milk can top 4 in position. The fastening device is made up of .two main 'elementsor members, of which the slide plate 11 is integral with the hook 10. This plate 11 is provided nf'fith a longitudinally extending slot 12 and near` one end is fashioned with a pair of side plates 13 and 14 projecting at right angles to the plane of the plate 11. In combination with the slide plate, I provide a complementary rack plate 15 with which the hook 9 is integral. This plate is located between the two side plates 13 and 14, and near one end the rack plate is provided with an integral lug 16 to slide in the slot 12 and guide the relative movement of the slide plate and rack plate when they are being adjusted. On its upper or outer face, the rack plateis fashioned with teeth 17 to forni a rack and a pawl 18 for coaction with this rack is l pivoted at 19 between the two side plates 13 and 14 of the main plate 11, and a means of a latch 21 which is pivoted at 22 in the side plates 13 and 14 and this latch is fashioned at one end with a friction lug 23 which engages and coacts with the pawl 18 to lock the latter in engagement with the teeth 17.

At the free end of the latch 21 are provided two side lugs 24 having perforated ends, and adapted to swing over the opposite edges or sides of the slide members of the shackle. through these perforated lugs and a seal 26 is used to fasten the ends of the wire cable together. f

It will be apparent that the length of the shackle or fastener may be adjusted by relatively moving the slide plate 11 and the rack plate 15 in order to adapt the device for use with milk cans in which the distance between the handle and the slotted top varies. By turning back the latch 21 to the dotted position in Fig. 3, the pawl 18 is automatically released from the ratchet teeth 17. The two main plates 11 and 15 may be adjusted with the lug 16 sliding in the slot 12 to guide the members.
