IMPROVEMENT IN FRUIT-JAR WRENCHES.

Specification forming part of Letters Patent No. 213,698, dated March 25, 1879; application filed February 8, 1879.

Heretofore such wrenches havebeen con-- structed by organizing several different parts and materlals into one device, which, no matter how well it may have served the purpose,

must be subject to the imperfections to which compound constructions are liable, some of which would ultimately reduce its strength and durability, and others its utility by renderin g it ditficult to clean and keep in order.

The object of our invention is to avoid these imperfections, and furnish a wrench that shall at once be clean,handy, light, cheap, and durable, having in fact all the merits which can be claimed for any others without their defects.

This we accomplish by constructing our wrench wholly of one material and substantially of one piece, preferably using as such material wood, as having most largely all the merits heretofore enumerated.

In the accompanying drawings, in which similar letters indicate like parts, Figure 1 represents our improved wrench in operative position. Fig. 2 shows a plan view of the same. Fig. 3 shows the form as cut from the wood and before bending.

The handles A A, jaws B B, and band C are constructed of one piece, and, when of wood,

by sawing in such manner that the grain will be continuous through the band and a large part of the jaws and handles. The form is then steamed and bent into shape, after which the article is ready for use.

Care should be taken in making the wrench to select stock having sufficient thickness to form a band or strap connecting the handles which shall be practically rigid in cross-section, in order that at all times the handles shall remain substantially parallel and in the same plane, that they may be grasped by one hand whenever wanted.

This device may be formed of three pieces, as shown by the dotted lines in Figs. 2 and 3, without departing from the spirit of our 1n vention; but we prefer to construct it all 111 one piece, as there are then no scams or oints to accumulate dirt, or be damaged by moisture, rust, or other destructive causes.

It will be observed that by the use of wood we form a wrench which needs noadhesive facing within the band, the material itself being sufliciently adhesive to maintain a firm hold upon the jar. We thus avoid the use of material which is diflicult to clean and preserve in condition.

What we claim as new and of our invention A fruit-jar wrench having handles and jaws made of wood, united by a resilient band bent into shape and formed of the same materlal.
