Description

UNITED SIATESA PATENT OFFICE.
oLY sTANLEY ELEMI'NG, OE MONROE, LOUISIANA.
SELF-'ADJ USTING RATCH ET-WRENCH.'
SPECIFICATION forming part of Letters Patent No. 636,511, dated November '7, 1899.
Application filed March 18, 1899. Serial No..'709,594. (No modeLl To @ZZ whom, t may concern:
Beit known that I, GLY STANLEY FLEMING, a citizen of the United States, residing at Monroe, in the parish of Ouachita and State of Louisiana,have invented certain new and useful ImprovementsinSelf-Adjusting Ratchet- Wrenches; and I do declare the following to beafull, clear, and exact description ofthe invention, such as will enable othersfskilled in the art to which it appertains to make and use the same.
My invention relates to improvements in self-adjusting ratchet-wrenches; and the object is to provide a simple, inexpensive, efficient, and durable device of this j character.
To this end the invention consists in the construction, combination, and arrangement of the several parts of the device, as will be hereinafter more fully described,and particularly pointed out in the claims..
In the accompanying'drawings the same reference characters indicate the same parts of the device in the several figures.
Figure 1 is a side elevation of my improved self-adjusting ratchet-wrench. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a transverse section on the line 3 3 of Fig. 2.
A and B denote the pivoted jaws, the jaw B being provided with an integral longitudinal shank b to receive the wrench-handle C.' The inner face of the jaw A is formed with a right-angular longitudinal groove a, and the corresponding face of the jaw B with aV simil lar groove b. Theoutside faces of both jaws are semicircular in forni, the jaw A being provided with a longitudinal rib d. and the jaw B with a similar rib h2.
D denotes a star-shaped ratchetwheel which encompasses the jaws A and B, and it is provided with recesses d and d to receive the ribs ctand b2, respectively, so as to have a sliding engagement therewith the entire length ofthe jaws. Y I o i E denotes the socket or head in which the,` ratchet-wheel is mounted, and it is provided with an operating-handle e. This headE car-1 ries the usual spring-operated ratchet-pawls e and e, which are alternately thrown int-o and out of engagement with the ratchet-wheel 5o D by means of the milled collarF inthe usual manner common to ratchet wrenches and drills.
The manner of using the tool will be fully understood by those skilled in the art upon referring to the drawings, all that is necessary being to slide ratchet-wheel up toward the hingeY and then `separate the jaws to encompass the nut X. The'ratchet-wheel is now slipped down on the jaws to close them about the nut, the wrench-handle C being held in one hand while the ratchet-handle e is manipulated by the other hand in the usual manner to set up or release the nut. l The accompanying ldrawings show my invention in the best form now known to Ine; but many changes in the details might be made within the skill of a good mechanic Without departing from the spirit of my invention as set forth in the claims at the'end of this specification.
Having thus fully described my invention, what Iclaim as new and useful, and desire to secure by Letters Patent of the United States, 1s-
1. In a ratchet-wrench, the pivoted jaws formed with exterior' longitudinal ribs, in
nesses. y
