WRENCH- APPLICATION FILED MAR.12,1921- 1 ,405, 140, Patented Jan. 3 1-, 1922.
WM U8 i ATTORNEY.
UNITED STATES PATENT omce DAVID EMANUEL LUNDBERG, 0F PHILADELPHIA, PENNSYLVANIA.
WRENCH.
To all whom it may concern Be it known that I, DAVID E. LUNDBERG, a citizen of Sweden, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.
This invention relates to improvements in wrenches and more particularly to nut wrenches. One object is to provide a wrench in which the movable jaw can be disconnected from its carriage and moved freely over the body of the wrench so that a carriage when broken can be readily replaced without the necessity of providing a complete new jaw. A further object is to provide a simple wrench that is cheap to manufacture and efficient in use. With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be'hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawing which forms a part of this application and in which- Fig. 1 is a'rear edge view of the wrench.
Fig. 2 is a vertical sectional view of the same with the movable jaw shown in an altered position in dotted lines.
Fig. 3 is a sectional view taken on line 3-3 of Fig. 2.
Figs. 4. and 5 are fragmentary views illustrating opposite sides of the movable. jaw.
Like reference characters denote corresponding parts throughout the several views.
The reference numeral 1 denotes the body portion of the wrench which at one end terminates in the integral fixed jaw 2 and at the opposite end is provided with the rotary thumb nut 8. said body portion beingv formed with the longitudinal slot 4 which registers with the reduced bores 5, 6 in the wrench body and in the thumb nut respectively, and with a perforation 7 in the jaw 2. A screw shaft 8 extends entirely through the wrench body, jaw 2. and thumb nut and is secured to the latter by means of the pin 9. A threaded carriage 10 is arranged upon the threaded portion of the screw shaft so that rotation of said shaft moves the carriage longitudinally thereover.
The carriage 10 is provided with the two diametrically opposed headed pinsll which are adapted for disposal in the oppositely curved slots 12, 13 formed in the lateral Specification of Letters Patent Patented J a 31 1922. Application filed March 12, 1921. i
Serial No. 451,787.
faces of the movable jaw 14 whereby said jaw is removably secured to the carriage The slots in the jaw 14 have their upper or straight ends disposed upon opposite sides of the screw shaft as will be seen by reference to Figs. 4 and 5 and. the width of the .slots is such that the stems of the pins 11 may be disposed therein when posi- V tioned at an oblique angle thereto. pins 11 when disposed in the straight ends of the slots may be moved to the lower or curved ends thereof by manually raising the jaw 14 when the pins 11 upon riding into the curved slot ends will move the carriage 1O slightly upon the screw shaft but when the pins are in the positionsshown in Figs.-
eland 5 the jaw 14 is securely attached to and movable with the carriage. The carriage is removed from the jaw by applying the fingers of one hand to the pin heads and imparting a twisting motion thereto to move the pins back into the straight portions of the slots. The jaw may now be moved away from the carriage over the body portion 1 of the wrench.
WVhat is claimed is 1. In a wrench, a body portion, a fixed jaw carried thereby, a screw shaft extending through said body portion, a carriage arranged upon said screw shaft and movable longitudinally thereover, and a movable jaw slidable over said body portion and releasably' secured to said carriage.
2. vIn a. wrench, a longitudinally slotted body portion, a fixed jaw at one end of saidable jaw being curved in opposite directions,
and headed pins carried by said carriage for removable disposltion 1n the slots of said movable aw.
The
In testimony that I clalm the foregoing as my own I have hereto affixed my signature in the presence of two subscribing wltnesses.
