Application lled January 5, 1923. Serial No. 010,881.

i To all wihom it may concern.'

Be it known that I, WILLIAM Pn'rEnsnN a citizen of the United States, residin at be Witt, in the county of Saline and` tate of Nebraska, have invented certain new and useful Improvements in Wrenches, of which the followin is a specification, reference bein `had to t e accompanying drawings.

his invention relates to certain improvements in wrenches and it is an object of the invention to provide a device of this general character having novel and improved means whereby the same can be employed with equal facility as liers and which can also be employed in su stantially the same manner as a ratchet wrench and alsovas a pipe wrench.

Another object of the invention is to provide a novel and improved device of this general character comprising a stationary jaw and a movable jaw together with means for shifting the movable jaw relative to the stationary jaw.

It isalso an ob'ect of the invention to provide a novel an improved device of this general character comprisin a stationary jaw and a movable jaw toget er with an articulated lever associated with the movable jaw for adjusting the same relative tothe stationary jaw, one of the sections of the l articulated lever being extended to provide an operating handle.

Another object of the invention is to provide asnovel and improved wrench embodying a `stationary jaw and a movable jaw t0- gether with operating means for the mov able jaw wherein a retractable member is asl sociated with said operating means for urging the movable jaw in a direction away from the stationary jaw.

The invention consists inthe details of construction-and in the combination and arrangement of the several parts of myy improved wrench whereby certain important advantages are attained and the device ren-` dered simpler, less expensive and otherwisel more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a View in side elevation illusl shank 3.

and bridges, the space therebetween.

trating a wrench constructed' in accordance e ings, A denotes an elongated handle member of channel formation but having its outer end portion 1 closed'as at 2, said end portion having threaded axially therethrough a The outer end portion of ythe shank 3 is provided with a head 4 whereby said shank may be conveniently adjusted. The inner end portion of the shank 3 is provided with a point 5 for a purpose to be hereinafter more particularlyreferred to.

The opposite end portion of the handle A is provided with la stationary jaw 6 herein disclosed as having its working face disposed on an angle of approximately 2% degrees with respect to the handle A. The portion 7 of the handle A immediately adjacent to the jaw 6 is transversely enlarged and the outer or (free edges of the side walls or' said enlarged portion 7 are arcuate and disposed on a curvature concentric to the pivot member or pin 8.

The member or pin 8 is supported by the side walls of the portion 7 of the handle1 A 'l iis pin or member 8 is also freely disposed through an inwardly directed wing or llange 9 carried by the movable jaw l0. 'The Wing or flange`9 fits substantially snug between the side walls of the portion 7 of the handle A while the under surface of said jaw 10 at opposite sides of the wing or flange 9 has close contact with the outer arcuate edges just hereinbefore referred to.

The working face is disposed on such angle that when the movable jaw 10 is at the limit of its movement toward the stationary jaw 6 the outer ends of said jaws 6 and 10 jaws relatively adjusted for use are in contact with the opposed working lll iently used' as pliers. The working faces of the jaws 6 and 10 are also roughened in a conventional manner to facilitate their gripping action when the tool is employed as a. wrench.

The inner end portion of the movable jaw 10 has pivotally engaged therewith a. section 11 of an articulated lever, said lever comprising two sections the second section 12 being adapted to extend within the handle A and have contact with the inserted and of the shank 3. The pivoted end portion of the section 11 'of the articulated lever is extended to provide an operating handle 14. Upon pressure being imposed upon the lever and with the section 12 in contact with the inserted end of the shank 3 the movable iaw 10 will be forced toward the stationary jaw 6 whereby the work may be effectively gripped between said jaws.

Engaged with the wing or flange 9 of the movable aw 10 at a point outwardly of the pivot member or pin 8 is an end portion of the retractible member 15, herein disclosed as a coil spring, the opposite end portion of said member 15 being suitably enchored to the handle A. This retractible member or spring 15 provides means whereby the jaw 10 is automatically moved into open position so that my improved tool may be employed with substantially the same convenience and the effectiveness as a ratchet Wrench.

By moving the shank 3 inwardly or outwardly of the handle A the fulcrum for the section 12 of the articulated lever may be adjusted as the necessities of practice may prefer and whereby the jaw 10 may be adjusted relative to the jaw 6 in accordance with the work and which adjustment may le made as desired and to the closest possible e ree.

it has been fully demonstrated in practice that my improved tool can be engaged with the work with the grip of a vise and par ticularly when the operating handle 14 has been swung outward and the handle A is beyond center and the shank 3 adjusted to further force the jaw 10 into engagement with the work interposed between the jaws 6 and 10.

The outer or free end of the second section 12 of the articulated lever is provided with a pocket or recess 16 which receives the point 5 provided at the inner or inserted end of the shank 3. By this means the section 12 is maintained in effective'engagement with the shank 3 and more especially during a working operation.

From the foregoing description it is thought to be obvious that a Wrench constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which `it may be assembled and operated, and it carryin out m invention in practice exce t as ereina r claimed.

claim:

1. A tool of the class described, comprising, in combination, a handle provided with a stationary jaw, a movable jaw, means for pivotally connecting the movable jaw, an articulated lever having one section pivotally engaged with the movable jaw, a member adjustable lon itudinally of the handle and wlth which' t e second section 'of the articulated lever is adapted to contact, and automatic means for moving the movable jaw in a direction away from the stationary jaw. j

2. A tool of the class described comprising a handle member of channel formation provided with a stationary jaw, one end portion of the handle member being closed, a shank threaded through said closed end portion of the handle member, a movable jaw carried by the handle member for coaction with the stationary jaw, an articulated lever having one end portion pivotall connected with the movable jaw, a secon section of the lever being ada ted to have contact with the inserted end o the shank, the first section of the lever being extended to rovide an operating handle, and means wit in the handle member 'and coacting with the movable jaw for automatically moving the movable jaw in aldirection away from the stationary jaw.

3. A tool of the class described comprising a handle member of channel formation provided with a stationary jaw, one end portion of the handle member being closed, a shank threaded through said closed end portion of the handle member, a movable jaw carried by the handle member for coaction with the stationary jaw, an articulated lever having one end portion pivotally connected with the movable jaw, a second section of the lever being adapted to have contact with the inserted end of the shank, the first section of the lever being extended to provide an operating handle, and a retractile member secured to the movable jaw and to the handle, said retractile member operatin to automatically move the movable jaw into open position. f

In testimony whereof I hereunto affix my signature.

WILLIAM PETERSEN.
