UNITED STATES PATENT OEEICED IMPROVED WRENCH.

Specication forming4 part of Letters Patent No. 50,364, dated October 10, lS.

To all whom 'it may concer/a:

Be it known that we, LUcrUs J oRDAN and LEANDER E. SMITH, ot' Southington, in the county ot' Hartford and State of Connecticut, have invented new and useful Improvements in Wrenches, and we do hereby declare that the following is a full, clear, and exact description thereof', which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specilication, in which- Figure l is a side elevation ot a wrench with a part in section to show the application ot' our invention. Fig. 2 is a top or face view of the ferrnle or step we use as a bearing for the nut y which operates the slidingjaw ofthe wrench.

Fig. 3 is an inverted-plan view ot' the nut which bears against the ferrnle, and which is recessed to receive the handle.

Similar letters ot' reference indicate like parts.

Onr invention consists in the employment or use ofa ferrule or s tep, into which is fitted to work the end or journal ot' the screw-rod which carries the nut by which the slidingjaw ot' the wrench is operated, and against which the said nut bears, and it further consists in the use of a nut which is screwed upon a thread cnt on the bar ofthe wrench,so thatitwillbearagainst the said ferrule or step and keep it rigidly in place, by which arrangement a strong' anti durable wrench is obtained, as will be hereinafter explained To enable others to understand our invention, we will proceed to describe it.

A represents the bar ot' the wrench, one part of which is made of the usual shape, and has the slidingjawB attached in the ordinary way. The other end is made of a i'orm capable of receiving upon it the wooden handle G of the wrench.

C is the screw-rod, and D the nut for operating the slidingjaw B of the wrench. E is a ferrule or step, into which rests one end, or, rather, the journal, ofthe screw-rod C, as shown clearly in Fig. l. The form ot' the ferrule or step E is shown clearly in Fig. 2, the hole tbeing for the admission through it of the bar A, which carries the handle of the wrench and the recess c for a bearing or journal-box for the.

screw-rod C. This ferrule or step, when in a proper position on the bar, rests against a shoulder, b, upon the bar A, as will be understood by reference to Fig'. l.

On the bar A, j ust below the place where the ferrule or step E encircles it, there is cut a screw-thread, c, on which is fitted to screw a nut, F, which is to be screwed up tirmlyagainst the ferrule or step E bet'ore the wooden handle G is putupon the wrench. A recess, d, is made in the lower face of this nut F to receive the handle G of the wrench, said handle being secured in place by a nut, d, at the lower end, in the usual way.

y this arrangement the wrench is niade far stro-nger than it would otherwise be, and therefore more durable.

In the ordinary wrench thestrain comes upon the wooden handle, which is hardl)v ever secured sufliciently rm to withstand the great strains to which the several parts ot' the wrench are oftentimes subjected. In our wrench the entire strain t'alls upon the nut, and this is secured on the bar ot' the wrench tightly and tirrnly against theferrule orstep, against which latter bears the nut that operates the sliding jaw of the wrench. A casual displacement ot' this nut F is not possible, and itis rtn enough to withstand any strain that the user is capable of subjecting it to.

The wrench operates easily, and it is not likel7 to get out of order.

That we claim as new, and desire to secure by Letters Patent, is-

1. The step E when held in place upon the bar7 substantiallyas and for the purpose herein set forth.

2. The nut F, iittctl to screw upon the barA, so that one of its sides or faces will rest against the step E and the other recessed to receive the upper end of the handle, substantially as described.

3. The combination ot` the step E, screw-rod C, nut D, and nut F, substantially as herein shown and described.
