L AL 7/ g F m I /5' F151- F155- FIBE- W1 TNE! 5 E E 5 INVENT DEL W NAPEILEUN. DUE EAULT NAPOLEON DUSSAUI JT, OF NEW BRUNSWICK, NEW JERSEY.
WRENCH.
Specification of Letters Patent.
Patented May 4, 1909.
Application filed October 21, 1907. Serial No. 398,421.
To all whom it may concern:
Be it known that I, NAPOLEON DUSSAULT, a citizen of the United States, and a resident of the town of New Brunswick, in the State of New Jersey, United States of America, have invented certain new and useful Imrovenients in Wrenches, of which the folfbwing is a full, clear, and exact description.
This invention relates to wrenches and the object is to provide a quick acting device that can be set to any position instantly and locked or unlocked with great ease and rapidity.
The invention consists essentially of a shank provided with a fixed head and a movable jaw similar to those employed in ordinary wrenches. The movable jaw is provided with a pivoted block, said block having its inner face toothed to cooperate with the toothed edge of one face of the shank. A resilient member holds said block normally out of engagement with the teeth of the shank,'while a pivoted linger member having an eccentric portion in contact with the pivoted block, is adapted to force said block against the toothed face of the shank when so desired.
In the drawings which illustrate my invention:Figure 1 is a plan view of the wrench turned on its side. view partly in section. of the wrench.
Referring to the parts, 1 designates a shank of cast steel or othersuitable material, provided with a fixed head 2, and a movable jaw 3.
4 designates a band adapted to hold the jaw 3 in slidable relation to the shank and alsoto contain at its front side the locltfiig lever. The band t is provided with aredss 5 adapted to contain the block 6 having in its inner face a plurality of teeth adapted to engage and cooperate with similar teeth formed in the shank 1. The block (3 is pivoted near its upper end at 6, and at its lower end is provided with a curved portion 8 adapted to cooperate with the eccentric end 9 of the finer lever 10, said lever being held in position y means of the pin 11.
Fig. 3 is a front "iew ignated by 10 in order to facilitate its out: ward movement .when resting a ainst the handle 13 of the wrench. The s hank 1 is provided with a plurality of teeth 12 forming Fig. 2 is a similar plan I The finger lever 1() is given a slight twist at its lower end, as dosa rack which is adapted to cooperate with the teeth of the block 6. The lower end of the pivoted block 6 is held normally out of engagement with the teeth 12 of the shank by means of a resilient member 14. As shown in Fig. 2, this resilient member consists of of a block of rubber or like material inserted within the recess between the upper end of the member 6 and the metal of the sliding jaw 3.
In the operation of the device, the finger lever 10 is thrown outwardly to the position shown in dotted lines in Fig. 1, during which movement the eccentric end 9 of the lever releases the block 6. The jaw 3 is then moved to the desired position. The resilient member 14 normally throws the upper end of the pivoted member 6 inwardly toward the shank of the wrench, while the lower end of said member is maintained out of engagement wit-h the teeth of-the shank. \Vhen the aw 3 is set to the desired position, the finger lever is pressed downwardly parallel with the shank, as shown in Figs. 1 and 2. the eccentric end 9 of said lever forcing the block 6 into engagement with the teeth 12.
' The jaws are thus firmly locked in position.
The member 1 c may be of any resilient material and may be placed in any convenient position with respect to the block 6, in order to serve the desired purpose.
Having thus described my invention, what I claim is In a wrench, a shank having a fixed jaw at one extremity thereof, a slidable jaw mounted on said shank, a plurality of teeth on the face of the shank adjacent the jaws, a lever pivoted within said slidable jaw, a toothed block integral with one extremity of said lever and adapted to engage the teeth of the shank, a resilient member mounted be.- t-ween the jaw and the opposite end of the lever and adapted to maintain said block normally out of engagement with the shank, a lever pivoted to said movable jaw adjacent the block, and an eccentric extremity on said lever adapted to force said block into engagement with the shank.
In witness whereof .l have hereunto set my hand in the presence of two witnesses.
