PERCIVAL F. KING, OF NEW HAVEN, CONNEtJTICUT.

WRENCH.

Application filed August 16, 1924. Serial No. 732,504.

My invention relates to certain new and useful improvements in wrenches and it particularly has for its object to provide a wrench ot' the sliding jaw type of a simple and effective construction that can be manu- -tactured at a low cost and effectively serve its intended purpose.

In its more generic nature the invention comprises a fixed jaw and handle with a slideway projecting from it, a slidalole jaw and handle having a slideway to cooperate with that of the first element, the two jaws being connected together to maintain their slideways in contact, the inclination of the slideways being such that as the movable jaw body is slid along the slideway the jaws will be moved toward and from each other accordingly. There is also provided means continuously tending to hold the jaws together and another means permitting the jaws to be separated by engagement with the object to be grasped in applying the tool to the object.

lVith other objects in view which will be apparent to those skilled in the art the invention in its more specific nature resides in those novel structures, combinations and arrangements of parts, all of which will be first fully described, then be specifically pointed out in the appended claims, reference being had to the accompanying drawing. in which Figure l is a side elevation of the invention, the jaws of the wrench being closed.

Figure 2 is a detail side elevation of a portion of the tool, the jaws being Figure 3 is an edge view. Figure l is a cross section on the line 44 or" Figure 1.

Y to

Inthe drawing in which like numerals of reference indicate like parts in all the figures, 1 is a body which at one end has a handle 2 and at the other end is provided with a jaw 4-. The body 1 also has a lateral projection having an inclined slideway or face 3 that. cooperates with the similar slideway or face 6 of the handling 7 of the sliding jaw 5. The jaw 5 is linked to the jaw body 1 by a link 12 on each side, which is pivoted at 18 to one body and at 14 to the opposite jaw. In order. to continuously tend to hold the jaws in engagement I provide a resilient means (preferably a spring) 11 located in a suitable socket 9 in the jaw members and secured to said members. A strap 8 is also provided on the body 1 to embrace the hanof which the body 'a laterally projecting inclined slideway, a

separated. I

' 7 move from and toward the other jaw with dle 7 of the jaw 5 opposite the slideway 6 and assists the links 12 in holding the faces 3 and 6 in contact.

15 is a nose secured to the jaw 5-, by means jaw 5 may be separated to enable the tool to grasp an object. or the separation may be'effected by pulling back on the handle 7.

The opposing faces of the jaws 4t and 5 may be serrated in the usual way if desired.

It will be noticed from the drawing that by the arrangement shown the movable jaw 5 will move from and toward the fixed jaw 4 while maintaining the another, or in other words, one jaw will move from and toward the other jaw with parallel movement.

From the foregoing description, taken in connection with the accompanying drawing, it is thought the complete construction, op eration and advantages of my invention will be clear to those skilled in the art.

What I claim is: r

1. In a wrench of the class described, a having a jaw and a handle and having second body havlng a jaw and a handle with a slideway to engage said first mentioned slideway and adapted to be moved lengthwise along the first mentioned slideway to separate the jaws or bring them together again, means holding the bodies with their slideways together and spring means conjaws parallel to one tinuously tending to hold the jaws in contact, said slideways and said body holding means being so arranged that one aw Wlll parallel movement.

2. In a wrench or" the class described, a

body having a jaw and a handle and having a laterally projecting inclined sl-ideway, a second body having a jaw and a handle with a slideway to engage said first mentioned slideway and adapted to be moved lengthwise along the first mentioned slideway to separate the jaws or bring them together again, means holding the bodies with their slideways together and springmeans con tinously tending to hold the jaws in contact.

said second body having a nose for the pur poses described, said slideways and said body holding means being so arranged that one jaw will move from and toward the other jaw with parallel movement.

3. In a wrench of the class described, a body having a jaw and a handle and having :1 lat rally projecting inclined slideway. a second body havin a an and a handle with a slideway to engage said first mentioned slideway and adapted to be moved length- Wiee along the first mentioned slideway to separate the jaws or bring them together again, links pivoted to the bodies to connect PERCIVAL F.
