UNITED STATES PATENT OF 'Ep ROBERT BUTLER, or nosroinivrnssnonusnrrs Wanner: Applicationfiled June; 5, 1931. Serial No. 542,301."
An object of this-invention is to provide a from the fixed jaw being limitedby the -stop wrench of the quick adjusting type which is of simple and durable construction, econom- 1 ical" to manufacture, and 'which may be quickly and conveniently adjusted. Another object is to provide a Wrench designedto minimize the danger of accidental disengagement of the movableja-w from its adjusted or locked position, and further to pro vide means affording a protection against accidental injury to the spring mechanism which normally holds the movable jaw in locked or adjusted position.
; positlon;
Further ob'eots and advantages will be apparent from a consideration of the following description and accompanying drawings which exemplify one embodiment of this invention chosen for the purpose of illustration.
In the drawings:
Fig. 1 is a side elevation of the wrench with the movable jaw in operative position;
Fig. 2 is a view similar to Fig. 1 showing the movable jaw moved from its operative Fig. 3 3-3 of Fig. 1'; and
Fig. 4 is acomposite view of the spr ng .member.
' Referring tothe drawings, the improved wrench shown therein comprises a shank 10 having a ribbed portion 11 providing a longitudinally extending abutment, and a fixed jaw 12 integral with one end of the shank. The sleeve 18 slidably mounted on the shank 10 is integral with the movablejaw 14: and carries theworm or thumb screw 15 which engages the teeth 16 on the shank. The
, sleeve is provided with a flaring opening or bore, as shown in Figs. 1 and 3, which permits a rocking movement on the shank todisengage the worm 15 from the teeth 16 thereby permitting the sleeve to be moved 5 freely along the shank, its movement away is an enlarged section on the line pin 17. 1
The sleeve is provided with an opening18' and a slot 19 adjacent to the rib ll of the shank. The benteup end 21 of the U-shaped 5o spring is anchored in opening. 18 and its opposite end 22,.disposed in slot 19, yield- "ingly'engages the rib llfirrespective of the.
relative position of the sleeve-and shankand normally holds the worm 15 in operativeen: x
able jaw in adjusted positionandpermitting 6;}
a fine adjustment from thatposition.
It willbe noted that the wrench herein shown and described is free from projecting parts and consequentlythe danger of accidental disengagement of the movable jaw from its locked or adjusted position isgreatl 7 1y minimized. Furthermore the spring member 20 being housed between the sleeve and shank is afforded a substantial protection against accidental injury. The springfQO is of such simple an'detiicient design that itmay be manufactured economically, assembled with facility and, in emergency, replaced by an-improvised spring. r
