T. s. KIZER.
SOCKET WRENCH. APPLICATIQN FILED SEPT- 3, 1920.
1,395,585. Patented Nov. 1, 1921.
r Be it known that I, THoMAs hereinafter.
UNITE. S A
PATENT OFFICE.
THOMAS S; KIZER, CHATTANOOG-A, OKLAHOMA.
' seeker- WRENCH.
T 0 all whom it may concern."
S. KIZER, citizen of the United States, residing 'at Chattanooga, in the county of Comanche and State of Oklahoma, have invented certain wherein the wrench jaws may be readily 'positioned to accommodate different sized nuts;
the jaws together. may be increased simply by increasing the forward pressure against the jaws. I
And the invention has a still further object to provide a wrench which will be characterized by entire structural simplicity and which will provide a rugged tool. V
v Other and incidental objects will appear In the drawings; j j
Figure 1 is a perspectiveyiew ofmy im proved wrench showing the jaws thereof p j I I Fig. 2 is a vertical sectional view showing the wrench jaws retracted, this View more clearly bringing out the structural details of the wrench,
Fig; 3 is a transverse section on the line 3-3 of Fig. 2, looking in the direction of the arrows,
Fig. 4 is a perspective view showing-one of the wrench jaws in detail, and
Fig. 5 is a sectional View showing a slight modification of the invention. V
In carrying the invention into effect, I employ a hollow wrench head 10 enlarged toward its lower end and provided at its upper. end with a socket 11 for receiving a stock. Formed in the head to open'through the lower end thereof are oppositely disposed internal guide channels 12 each substantially T-shaped in cross section and the bottom walls ofwhichprovide upwardlyin clined wedging shoulders 13. Slidable upon the wrenchhead are companion jaws, let.
These jaws are preferably provided" with angular serrated jaw faces 15 and rlslng from the jaws are jaw shanks 16. The shanks 16 Specification of Letters Patent.
A further object of the inv'ention is to provide a wrenchavherein the jaws may be wedged into engagement with anut and wherein the wedging action tending to draw Patented N 0v. 1, 1921.
Application filed September 3, 1920. "(serial no. 407,840.
are tapered longitudinally and are substantially T-shap'ed in cross'section so as to slidably fit freely in the guide channel 12, the
outer SIClGS of said shanks defining upwardly inclined 'wedging' faces 17 coacting with the shoulders 13 of the channels.
said grooves are looking pins 19 slidably connecting the jaws'with the wrench head. The' aws may, of course, be shaped to fit a square nut asshown in the drawing or may be shaped to fit a hexagonal nut, and formed in the jaw shanks at their inner ends are mating recesses 20 adapted, when the jaws are fitted over a bolt to engage a nut thereon, to receive the projecting'end of the bolt.
-As will now belreadily understood in view of the preceding description, by simply holding 'the wrench head with its lower end presented downwardly, thejawsl will gravitate to projected position, the jaws being pro- H gressively spread 1n their downward movement. Consequently the jaws may then, as sugg'este'din Fig. 1, be readily engaged over a nut, when'by pre ssingdownward upon the wrench head, the shoulders 13 of the head wilhact' against the faces 17 of the jaw shanks for forcing the jaws toward each other with a wedging action and binding the aws 1n engagement with the nut, the effect the nut and, as will be seen, the grippingaction of the jaws may be increased by simply increasing the forward'thrust against the wrench head. As-will be noted, the
any inward pressure toward each other. As
willi be appreciated, this feature will be found of advantage when it is desired to simply engage the jaws about a nut without gripping the nut, mutilation being thereby avoided. I accordingly provide a highly eflective wrench structure and a socket wrench which is adapted for a wide range of use.
a slight modification of In Fig. 5 of the drawin s, I have shown this modification, a conical wrench head 21 is employed. Atits upper end this head is provided with a socket 22 asin the pre-- ferred construction, and formed in the head are inwardly converging channels corresponding to the channels 12. In these channels are mounted coacting jaws 23v slidably connected with the head by locking pins 24 corresponding to the 1 his 19" ofthe preferred construction. T e jawsf23 are 25," This ring may be moved upwardly upon the head so that the jaws maybe posltiojned downwardly to-enga e 'a nut, when the ring" may" then be 'move downwardly to'sur round the jaws, lockin the'jaws inengage ment with the nut; y iorci the ring downwardly over the j-aws,the jaw shanks mayibe relieved of any stress thereon tenda j aws'slidably connected ing' to, separate the jaws and when the" wrench is turned for rotating 'the nutthe ring will, Qf course, resist movement of the jaws away 'from each other; from the upper end portion-ofthe head i's upward displacement.
