Description

J. L..STEEL.
WRENCH.
APPLICATION IILED SEPT.26,1907.
Patented Dec. 8, 1908.
I Steeif l witnesses UNITED STATES PATENT OFFICE.
JOHN L. STEEL, OF 'OHILLICOTHE, OHIO.
WRENCH.
To all whom it may concern:
Be it known that I, JOHN L. STEEL, a citizen of the United States, residing at Chillicothe, in the county of Ross and State of Ohio, have invented a new and useful Improvement in Wrenches, of which the following is a specification.
This invention relates to wrenches provided with a sliding jaw, the object being to provide a wrench which is so constructed that the jaw can be easily and quickly adj usted on the shank to suit any size nut.
Another object of my invention is to provide very novel means for locking the jaw in an adjusted position.
Another object of my invention is to provide a nut which is exceedingly simple and cheap in construction, and one which is very efiective in use as the jaw is securely locked by applying pressure to the handle.
With these objects in View, the invention consists in the novel features of construction, combination and arrangement of parts, hereinafter fully described and pointed out in the claims.
In the drawing forming a part of this specification :Figure 1 is a side elevation of my improved wrench. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a section taken on line 3-3 of Fig. 1. Fig. 4 is a section taken on line H of Fig. 1.
In the drawing A indicates a longitudinal grooved shank provided with a jaw B at one end and an enlargement A at the other end, between which is mounted a cam-lever C on a pivot pin D, the other end of the lever being threaded and arranged on the lever is a wooden handle E, which is secured thereon by a nut E working on the threaded end of the lever, so as to securely hold the handle in place. The edges of the shank are provided with ratchet-teeth A adapted to mesh with ratchet teeth formed on the under side of the crossbar of a T-shaped bar F which is slidably mounted in the groove of the shank and is provided with an enlarged bifurcated end F adapted to fit over the cam-lever which is provided with a transverse pin G which extends out through slots F formed in the enlargement F of the bar F and it Specification of Letters Patent.
Application filed September 26, 1907.
Patented Dec. 8, 1908.
Serial No. 394,718.
will be readily seen that as the lever is moved outwardly, the teeth will ride downwardly on the inclined faces of the ratchet-teeth of the shank and when pressure is applied to the lever the teeth of the bar will ride upwardly on the teeth of the shank.
A jaw H is slidably mounted on the shank A and the bar F and it will be readily seen that by pushing the handle outwardly and shoving on the jaw with the finger, it can be readily adjusted to any size nut in a very few moments, and that when pressure is applied to the handle, the bar will clamp the jaw in that position so as to prevent it from slipping in either direction.
From the foregoing description it will be seen that I have provided a very novel wrench whichis strong and durable and composed of a very few parts which are so assembled that they are not liable to get out of order,
thereby overcoming the difliculties of a wrench of this character now in use.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination with a shank pro vided with fixed jaw and ratchet-teeth, of a bar mounted on said shank provided with coacting teeth, a jaw slidably mounted on said shank and bar, a cam-lever mounted in said shank connected to said bar, and a handle secured on said lever for throwing said bar into engagement with said movable jaw, for the purpose described.
2. In a wrench, the combination with a grooved shank provided with a fixed jaw, said shank being provided with ratchetteeth, of a T-shaped bar slidably mounted in said shank provided with ratchet-teeth, a jaw slidably mounted on said shank and bar, said bar provided with a bifurcated end, the walls of which are slotted, and a cam-lever mounted in the end of the shank provided with a transverse pin working in the slots of said bar, for the purpose described.
JOHN L. STEEL.
