To all lolwm it may concern:

Be it known that I, John Henry Mitchell of Bloomfield, in the county of Davis and btate ot Iowa, have invented a new and Im5 proved Lock for Hoops, of which the following is a full, clear, and exact description.

lhe invention will be first described, and then set forth in the claims.

Reference is to be had to the accompanyin»· io c lawings, forming a part of this specification^ in which similar figures of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of a shipping-case embodying my invention, and showing also 15 a clamp for drawing the lock-sections together. Fig. 2 is a partial vertical elevation showing ahoop in the fastened position. Fm 3 is a perspective view of the fastener-blocks’ Mg- 4 is a perspective view of a modified con20 struction of the fastening-blocks. Fig. 5 is a cioss-sectional view of the fastening-blocks shown m Fig. 4.

In constructing my improved hoop-lock I provide two blocks 11 11% which form the 25 main part of the lock. The blocks 11 11“ are pivotally secured direct to the hoops 10 bv passing the ends of the hoops around the cross-bar 12, with which the blocks 11 11“ are provided, after which the end of the hoop is 30 returned on itself and riveted, as shown. The blocks 1111“ are oppositely beveled and their beveled faces are formed with teeth 13 to cause them to interlock when brought together. To maintain the blocks in the inter35 locked position, a wire 14 is passed around the same and twisted, the blocks being formed with vertical grooves 15 for receiving the said wire.

1Edition to the wire 14, the fastenino·40 blocks may be formed as in Fig. 5, in which one of the said blocks is formed with a longitudinal slot 16“ for receiving a staple 16, that projects from the toothed face of the opposite block. The arch or bend of the sta45 Pie is of greater thickness than the base of the legs thereof, and its thickness is likewise greater than the width of the slot 16“. Thus the slotted block can only be made to engage I the opposite one by causing the forks of the said slotted block to pass each side of the 50 staple, and it can be unfastened only in the same manner, instead of being passed over the staple, after the manner of a hasp. By binding the blocks with a wire, as in Fig. 6, with the wire passed beneath the bend of the 5 5 staple, the said wire and staple -will prevent the slotted block from being moved out of engagement with the opposite teeth of the block. To provide for bringing the opposite blocks together, I have provided a clamp 20, (shown 60 in Fig. 1,) and which need not be further desci ibed, as it forms no part of the invention claimed herein.

Having thug described my invention, what
