ANTHONY H. WEBER, OF NEW ORLEANS, LOUISIANA.

WRENCH.

Application filed June 23, 1915.

To all whom it may concern:

Be it known that I, ANTHONY H. WEBER, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in renches, of which the following is a specification, reference being bad to the accompanying drawings.

My present invention relates broadly to new and useful improvements in wrenches and has particular reference to those of the type in which the movable jaw is provided with a threaded shank whereon operates a nut, for adjusting the movable jaw with respect to the fixed jaw.

One of the principal objects'of the present invention is to form the adjusting nut e1nployed in connection with the threaded shank of the movable jaw, as a two piece element which may be locked together for rotation as a unit when the movable jaw is to be adjusted or may be disposed in such relation to each other that the threaded shank of the movable jaw may be moved, unrestrictedly through the nut and the jaw thus quickly moved to the approximate adjusted position desired.

2 The above, and otherincidental objects of a similar nature, which will be hereinafter more specifically treated are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claim which is appended hereto and forms part of this application.

With reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention, as it is reduced to practice, and throughout the several views .of which similar reference numerals designate corresponding parts, Figure 1 is a side elevation; Fig. 2 is a detail view in plan of the bottom face of the upper section of the adjusting nut; Fig. 3 is a detail view in plan of the upper face of the lower section of the nut; Fig. 4 is a section on the line 44, of Fig. 1; and Fig. 5 is a detail vertical section taken through the nut and showing the two sections thereof arranged for adjustment of the movable jaw. v

In construction, my wrench as embodied in the accompanying drawings, takes for the most part, the form of an ordinary wrench, differing therefrom mainly in the construc- Specification of Letters Patent.

tion of the adjusting means. Preferably the shank 10 of the wrench is equipped with an integral fixed jaw 11, and a handle 12. A movable jaw 13 is mounted for sliding movement on the shank of the wrench, whereby it may be adjusted toward or away from the justing stem 16, which member extends at right angles to the movable jaw, from the outer face thereof. As disclosed best in Fig. 1, the member 16 is spaced from the shank of the wrench and is disposed in parallel relation thereto.

The adjusting stem or shank 16 is noncircular in cross section, being provided with two fiat parallel faces 17 and 18 and with two opposed transversely curved faces 19 and 20. These two curved faces are provided with threads, as in Fig. 1, so that when the nut, generally designated in Fig. 1, by the letter A, is properly set and rotated, the adjusting'stem will be moved longitudinally with respect to the wrench shank, for adjusting the movable jaw with respect to the fixed jaw.

The adjusting nut heretofore generally designated by the letter A, is formed in two ate groove 23. The opening 24 through the member 21 is provided with two smooth curvedwalls 25 and 26 and two curved walls 27 and 28, which are opposed to each other and each of which is provided with worm threads, as shown best in Fig. 5. The section 21 is provided with an opening having the characteristics of the opening 24 and has a' flat lower face, indicated at 29. A stud 30 depends from the face 29. This stud is designed to seat in the groove 23 for apu'rpose which will be hereinafter explained. The lower face of the nut section 21 is provided with a stop shoulder 31. from the base of which the lower face extends upward, to the apex of the shoulder. This shoulder is adapted to engage with a stop shoulder 32, which is adapted to limit the rotation of the section 22 in one direction upon the shoulder 15, for a purpose which will be hereinafter explained.

Attention is now directed to Fig. 4, where- 'in it will be seen that the two sections of thus disclosed, it now remains to describe the manner in which the nut is manipulated when the movable jaw is to be adjusted. l/V'hen it is desired to displace the movable jaw from engagement with a pipe or other article held by the wrench, and to quickly 7 produce a wide space between the fixed and movable jaws, the section 21 is turned-upon the section 22 in a right-hand direction,

until the stud 29 is engaged in the end of the groove 23. When the stud is thus dis- 7 posed, the smooth 7 walls of the opening through the two sections of the nut will be alined. Then, by continuing to turn the upper section 21, it is obvious that the two sections will rotate in the same direction as unit, until the shoulder 32 engages with the shoulder 31. When these two shoulders are engaged, the smooth walls of the nut A are disposed opposite tothe threads on the two curved faces 19 and 20 of the adjusting stem or shank 16, while the threaded walls of the nut arerdisposedjopposite to the fiat parallel faces-17 and 18 of the stem 16. Ihus the adjusting stem 16 may be slid back into the bore 15, without any opposition, so as to quickly space the movable jaw from the fixed jaw.

When the movable jaw is to be minutely adjusted, the section 21 of the nut is turned to the left, until the stud 29 engages'the other 'end of the groove 23, in which position of the stud the threads of the one section are alined with the smoothunthreaded faces of the opening in the other section. When the two sections of the nut are thus disposed, the nut is adapted to be rotated as a unit, and to have its threads engagedat all times with the threads of the member 15.

In this connection, it will be apparent that when the threads of the section 21 are moved during the rotation of the nut, to a position opposite the flat faces of the member 18,

the threads of the other nut section 22 will be in engagement with the threads of the member 15.

Obviously, the nut may be initially adjusted to a considerable range by so disposing the two sections of the nut that the member 15 may freely slide therethrough. Then the more minute adjustment of the jaw may be accomplished by turning the nut so that the threads of the two sections.

thereof will continuously engage with the threads of the member 15. The jaw may be. held against movement from the desired adjusted position by allowing the two sections of the nut to remain in such position that the stud 29 engages in the right-hand end I of the groove 23.

Having thus described this what is claimed is: V

A wrench including a shank havingv a fifed jaw on one end and a laterally ofiset handle portion on its other end, said handle being provided with a rectangular longituinvention,

dinal bore, an adjustable jaw slidable on the wrench shank, a stem-fixed atone end to said jaw and slidably engaged in the bore of the handle, said stem being provided with threads on its opposite faces, and an adjustin'g nut consisting of two superposed secsections being provided with shoulders adapted for contact with each otherin the latter arrangement of the nut sections to;

prevent a further unitary rotation in-one direction of the nut with respect to said stem.

In testimony whereof Ihereuntoaffix my Witnesses ALEX. REED, FRANK STORTZ.
