JOHN J. HENRY, OF MASON, ILLINOIS.

WRENCH.

Application filed April 4, 1916. Serial N 0. 88,872.

To all whom it may concern:

Be it known that I, JOHN J. HENRY, a citizen of the United States, residing at Mason, in the county of Effingham and State of Illinois, have invented a new and useful l/Vrench, of which the following is a specification.

This invention relates to wrenches, one of its objects being to provide a quick adjustable wrench having means movable on the shank thereof and cofiperating with the handle of the wrench whereby a supplemental tightening of the jaws of the wrench upon a nut or other object can be elfected after a quick adjustment has been effected.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the inven tion.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :F igure 1 is a vertical longitudinal section through the sliding member of the wrench, the remaining portion of the wrench being shown in elevation, a portion of the handle being broken away. Fig. 2 is a section on line A-B Fig. 1. Fig. 3 is a section on line CD Fig. 1.

Referring to the figures by characters of reference 1 designates an angular shank having a handle 2 at one end while fixedly connected to the other end of the shank is a One edge of the shank is formed with ratchet teeth as shown at 4:.

The shank 1 is surrounded by a sleeve 5 which is slidably mounted thereon, this sleeve being exteriorly screw threaded as shown at 6 and projecting toward the handle 2 from a yoke 7 which is likewise slidably mounted on the shank and has a movable jaw 8 at one end. Yoke 7 is hollow, as at 9, and within this yoke is pivotally mounted a dog 10 having a toothed projection 11 designed normally to engage certain of the ratchet teeth 4:. A coiled spring 12 is arranged within the yoke and bears within a socket 18 formed in the dog 10. Thus the toothed portion of the dog is held yieldingly in engagement with the ratchet teeth 4:- A stud 14 extends from one end of the dog and through an opening 15 in the yoke and constitutes' a finger piece which, when depressed, will disengage the dog from the ratchet teeth 4: and permit the yoke and the parts connected thereto to be moved freely along the shank 1.

An adjusting sleeve 16 is mounted on the threaded sleeve 5 and extends preferably throughout the length thereof.

In using the wrench the j aw 8 is adjusted up to the article, such as a nut, which may be inserted between the jaws, this adjustment being quickly made in view of the fact that the toothed end 11 of the dog will slip over the teeth 4; during the movement of the jaw 8 toward the jaw 3. As soon as the article has been engaged by both jaws, the sleeve 16 can be partly unscrewed from the sleeve 5 until the end of sleeve 16 is brought against the end of handle 2, whereupon sleeve 16 will act as a means for forcing the aw 8 away from the handle 2 so as to bind the inserted article against the two jaws 3 and 8. The use of the sleeve 16 as a means for minutely adjusting the wrench is not necessary under ordinary conditions. When it is desired to release the article between the jaws, stud 14 is depressed so as -to disengage dog 10 from the ratchet teeth 4, whereupon jaw 8can be slid toward the handle 2. If, however, the sleeve 16 is already in engagement with handle 2, it will be necessary to screw this sleeve onto sleeve 5 before moving j aw 8 away from the jaw 3.

It will be seen that the ratchet teeth 4: are always housed within the yoke 7 and the sleeve 4 and, consequently, cannot be injured nor can they become clogged with dirt or the like. Suitable packing may be arranged wherever desired to keep dust and moisture out of the wrench and as this arrangement of packing is obvious, it is not deemed'necessary to show or describe the same in detail.

What is claimed is A wrench including a shank having a longitudinal series of ratchet teeth, a handle at one end of the shank, a fixed jaw at the other end, a slidable jaw, a yoke movable with the slidable jaw, a spring pressed dog pivotally mounted within the yoke and normally engaging the ratchet teeth, thereby to hold the movable jaw against movement in one direction relative to the fixed jaw,
