CLEVELAND J. ARCHEY, OF MOUNT VICTORY, OHIO.

WRENCH.

Specification of Letters Patent.

Application filed. June 6, 1913.

Patented May 12, 1914.

Serial No. 772,170.

To all whom it may concern Be it known that I, CLEVELAND J. ARGHEY, a born citizen of the United States, residing at Mount Victory, in the county of Hardin and State of Ohio, have invented new and useful Improvements in renches, of which the following is a specification.

The present invention relates to improvements in wrenches, and consists in the construction, combination and arrangement of parts set forth in the following description and pointed out in the claim.

The primary object of the invention is to provide a simple and practical quick adjustment wrench which will be strong and durable and. comparatively inexpensive.

The above objects of the invention are attained in its preferred embodiment illustratedin the accompanying drawings, and in which:

Figure 1 is a side elevation of the improved wreneh, Fig. 2 is a view partly in longitudinal section, and Fig. 3 is a perspective view of the operating sleeve.

Referring now to the drawings in detail, the wrench is indicated broadly by the numeral 1. The wrench comprises a stationary head or jaw 2 which is provided with a longitudinally arranged transversely extending shank 3. This shank for a portion of its length from its juncture with the head or jaw 2 is substantially rectangular or noncircular in cross section, the said portion be-- ing indicated by the numeral. 1, while extending beyond the said. portion 1 the shank is rounded and threaded, as at 5, the threaded portion being provided with a handle 6.

The numeral 7 designates the movable jaw for the wrench. The movable jaw has its forward portion provided with a rectangular opening for the reception of the rectangular portion t of the shank 3. Connecting the jaw proper with a collar 8 is a web 9, the said web having a lower flat face which is disposed over one of the straight sides or faces of the portion st of the shank. The collar is provided with a reduced bore 10 and an enlarged bore 11. The bore 10 is of a size sufficient to snugly receive the rounded portion of the shank, and the enlarged bore is arranged upon what may be termed the outer edge or end of the collar. The collar 8 is adapted to be arranged adj acent the shoulder pro-vided on the rectangular portion 4 and the rounded portion 5 of the shank 3 when the head of the movable jaw is brought into contact with the head 2 of the wrench proper.

The numeral 12 designates a sleeve which is adapted to receive the threaded and rounded portion 5 of the shank This sleeve has, what may be termed its inner end, provided with an angular flange 13, and the flange is adapted to be received within the enlarged portion 11, of the bore of the collar 8, and to be retained therein through the medium of removable elements, in the nature of screws 'l-il which pass through the collar and which engage with the outer face of the flange 13. Such an a rrangcment effectively connects the sleeve with the movable jaw, but in no wise interferes with the rotation of the sleeve, as will be readily understood. The threaded portions of the shank comprise abrupt shoulders which are disposed nearest the head 2, while the remaining portions of the teeth are inclined rearwardly to the succeeding shoulder, as is clearly illustrated in the drawings. The sleeve 12 adj accnt its end not provided with the annular flange 13 has diametrically opposite, substantially rectangular openings 15 which communicate with the bore of the sleeve and it may here be stated that the said here of the sleeve is smooth, or not threaded. The sleeve directly opposite its openings 15 is formed with outwardly extending cars 16, arranged in pairs adjacent the longitudinal walls of the said openings 15.

The numerals 1717 designate the actuating dogs for the wrench. These dogs comprise each a body portion which is adapted to be snugly received within each of the openings 15, and the inner faces of each of said dogs is threaded, as at 18, the said threads being arranged directly reverse to the constmurtion of the threads upon the shank. The dogs have their outer faces provided with rearwardly extending tail portions 19, while arranged between the tails and bodies of the dogs are lugs 20, and the lug of each of the dogs is adapted to be received between one of the. pairs of cars 16 and to be pivotally connected thereto through the medium of pins 21. Disposed between the tail portions 19 and arranged within suitable depressions in the sleeve central of its cars 16 are helical springs 22 which are adapted to exert a tension upon the tails of the dogs to force the teeth or threads of the dogs into engagement with the threads of the shank. The projecting ears 16, as well as the portions of the dogs and longitudinal movement of the movable jaw upon the shank 8 is thus readily provided. The arrangement of the teeth of the dogs and the teeth of the shank is such as to prevent a rearward movement of the movable jaw in a rearward direction from the stationary jaw when the dogs engage with the threads of the shank.

From the above description, taken in connection with the drawings, the simplicity of the device as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such inventions appertain without further detailed description. It will be noted that when the movable jaw is brought toward the stationary jaw and a firm grip is desired between the jaws and the article grasped by the jaws, a rotary movement of the sleeve will force the movable jaw toward and in engagement with the article arranged between the jaws.

Having thus described the invention, what I claim as new is:

A wrench including a stationary jaw hav- Losers?! ing a shank and a handle connected with the shank, the said shank being rectangular in cross section for a distance from its juncture with the head of the jaw and from thence being circular and threaded, a movable jaw, said jaw comprising a head having a, rectangular bore to receive the rectangular portion of the shank, a collar spaced from the head through the medium of a web, a revoluble sleeve connected with the collar and surrounding the threaded portion of the shank, said sleeve having oppositely disposed openings, and ears arranged adjacent the openings, dogs having body portions provided with threaded faces received within the openings andengaging with the threads of the shank,'the said dogs being further provided with tail portions which extend over the sleeve and the ears of the sleeve, the tail members having lugs which are disposed between the ears and which are pivotally connected with the ears, and spring members arranged between the tail portions of the dogs and received in depressions provided in the sleeve adjacent to and between its ears.

In testimony whereof I aflix my signature in presence of two witnesses.
