TAYLOR CARTER AND BOWEN HENRY, OF FRANKFURT, KENTUCKY.

RATCHET-WRENCH.

SPECIFICATION forming part of Letters Patent No. 657,512, dated September 11, 1900. Application filed February 27, 1900. Serial No. 6,745. (No model.)

To (LZZ whom it may concern:

Be it known that we, TAYLOR CARTER and BOWEN HENRY, citizens of the United States, residing at Frankfort, in the county of Franklin and State of Kentucky, have invented a new and useful Ratchet-Wrench, of which the following is a-specification.

This invention relates to improvements in wrenches, and particularly to that class known as ratchet-wrenches,

An objectof the invention is to produce a wrench of this character which maybe quickly and readily adjusted to be operated either right or left.

Another object is to provide a wrench which may be quickly adjusted to nuts of various sizes.

A further object is to construct a wrench which may be conveniently used upon rods or pipes.

A still further object is to construct a wrench of a minimum number of parts, thus simplifying the same and reducing the cost of production.

With the above objects in view the invention consists of a handle or stock having a head formed thereon, a disk rotatable insaid head and formed with a ratchet and a stationary jaw, an adjustable jaw carried by said pointed out in the claims, and illustrated by the accompanying drawings, in which Figure 1 is a perspective View of my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal sectional view. Fig. 4 is a transverse section taken on the line 4 4 of Fig. 2. Fig. 5 is a perspective view of the ratchet-disk.

Referring now more particularly to the accompanying drawings, A designates the handle or stock of the wrench, having formed integ rally therewith the circular plate B,formed with a circular slot or opening, and O a similar plate detachably secured to said handle, said plates being removed from each other,

so as to leave a space therebetween, and constituting the head of the wrench receiving the ratchet-disk. This ratchet-disk is formed about its periphery with the ratchet-teeth D, which occupy the space between said plates, and on each side of said ratchet-teeth with the flanges E, which extend into the circular slots of theplates. Formed on said disk and extending laterally of the wrench is a stationary jaw F. Said disk is slotted, as illustrated at G, and formed on the sides of said slot with the flanges or track H. Movable in said slot is an adjustable jaw I, having suitable grooves formed therein to receive said track upon which it moves and formed with the threaded stem J, which projects from said disk and receives a suitable clamping-nut K and washer L. Thus this movable jaw may be adjusted to and from the stationary jaw, so that the wrench may be made to accommodate-nuts of various sizes. The jaw F stands at one end of the slot G, with its inner face even with the end wall of the slot, and the jaw I projects fromsome intermediate portion of the slot, so that there is always a hole or opening 7 through the disk equal to the distance between the two j aws,thercby permitting of the wrench being used on pipes or bolts where it is necessary for them to project through the wrench.

Positioned in suitable recesses in the handle or stock are the dogs M, formed on their outer ends with oppositely-disposed ratchetfaces N, said jaws being normally held in engagement with the ratchet of the disk by the coil-springs O. A pin P is carried by each dog, the same extending laterally therefrom and movable in a slot Q, formed in said handle. Said pins project through the slots of the handle, and pivoted upon the exterior of plate B by a screw passing intermediately therethrough is a thumb-piece R, which is adapted when moved in one direction to disengage one of the dogs from the ratchet and hold the same therefrom and when moved in the opposite direction to effect a similar may be operated either right or left, astmay be desired. It will be noticed that the clamping-nut for the adjustable jaw and the thumb piece for shifting the dogs are both located on the same side of the wrench, where tlfiei may be .o'rfire'fi'ieiitly "operzi'ted; The stockor handle is formed in its end with the Wren ch portion S, adapted to engage nuts of 'various SIZGS. o

Byt-forming on eof the plates of the heed intgi'iilly with the" stac 6i li'ii'i'dle and me" stationary jaw integrally with the ratchetdisk it will be understood that the'ljiimlief of parts employed in the wrench is reduced and the construction thus simplified and a reduc-- tion effected in the costlof production.- V

The wrench may be convenient y positioned upon a pipe or red bi 'iri'siei'ti'ti i the Sfiijie" thereon, the pipe or rod passingthrough the hei' i-sk" sl'dt 'fite mte l H Having thus escu )ed 0111-invemiemwns we e aim as new, 51nd d'esii e t6 secure I)?
