UNITED STATES fPATEN-T OFFICE.
RAYMOND A. MULL, OF BENTON HARBOR, MICHIGAN.
WRENCH.
Application lled .Tune 16, 1924.` Serial.l No. 720,204.
'Benton Harbor, Berrien County, Michigan,
have invented a certain new and useful Imrovement in'Wrenches, of whichthe folowing is a specification.
This invention relates to wrenches, and more particularly to those having a pivoted or self-adjusting engaging portion for one jaw of the wrench.
Generally stated, the object of the inven-v tion is to provide an improved and novel construction and arrangement whereby the connection between the movable or self-adj usting portion and the jaw upon which this portion is mounted, is of such character that there will be no danger of shearing orbreakage of the pivotal or other connection-between the jaw and said portion, wheny the wrench is used for the purpose for which' it is intended.
It is also an object to provide certain details and features Vof construction tending to increase the general efliciency and the desirability of a wrench having a movable or selfadjusting face or engaging portion for one jaw thereof of this particular character.
To the foregoing andother useful ends the invention consists in matters hereinafter set forth and claimed and shown in the accompanying drawingsin which- Fig. 1 is a side elevation of-a wrench embodying the principles of the invention, showing a portion of the handle broken away for convenience of illustration.
Fig. 2 is a similar view showing the head of the wrench in vertical section.
Fig. 3 is a horizontal section on line 3-3 in Fig. 2.
Fig. 4 is a perspective of one of the parts of the wrench.
As thus illustrated, the invention comprises a handle 1 which is rigid with the upper jaw 2, the lower jaw 3 having a portion 4 that slides up and down in the guideway 5 formed in the body portion 6 of the wrench. The portion 4 has teeth 7 to engage the screw 8 which is mounted upon an axis member 9 which is screwed into the body of the wrench, whereby rotation of the member 8 will cause up or down movement of the j aw 3 previously mentioned. The edges of the screw thread on the member 8 canvbe roughened to facilitate rotation thereof by the thumb and finger. The jaw 3 is provided transversely with a groove 10 which is cyi lindrical andv provided with a restricted opening 11 atits upper side. The self-adjusting engaging portion 12 isprovided with a tongue 1 3formed.transversely thereof, on
asmuchV as the opening .'11 is narrower than the diameter of the tongue 13, it follows that the tongue must `enter the groove"endwise,
'and must be displaced endwiseor axially therefrom, inasmuch' as axial'insert-ion and removal of the tongue 1 3 in 'the groove 10 necessary with the construction shown and described. vIn order tojlockthe engaging its under side, and this tongue 13 fits the l portion 12 against lateraldisplacemena-by e axial movementfoff the tongue 13 J in the' grooveflO, the Said tongue" is preferably provided on'its 'under side witha notch'l', and a pin 16 is inserted through the jaw 3 into this notch, whereby the portion 13 is held against displacement, but at the same time has perfect freedom of rocking motion, the notch 15 being formed in a manner and of sufficient size for this purpose. To hold the portion 12 normally in the position shown, a coil spring 17 is seated in a socket 18 formed in the jaw 3, in position to bear upwardly against the under side of the inner end portion of the engaging portion 12, in the manner shown. The pin or other retainer 16 may be a loose pin, of course, disposed at one side of the spring 17, as shown, and in such event the pin is held against displacement by the body portion 6 of the wrench, as the end of the pin moves up and vdown against said body portion when the parts are properly assembled.V With this construction, the portion 12 can rock about its'axisl to be turned, such as a pipe or a rod or other obieeo, end in this wey the portion 12 Will accommodate itselffor adjust itself to `the position most effective for turning the object to which the wrench is :,Lpplied.` The tongue and groove 13 and 10 Vform a very strong pivotal connection between the portion 12 and the jaw 3, which will not'be easily broken, for the Vpressure when the wrench is applied to an'object is transmitted through the Portion 1Mo the lover Seele et the fon'enell3,enel from ,fable tonene. to .elle javi/A3, and hence pivotal connection is proireleol Wlioh Jeannot sheer or breek or be otherwise injured by the' use of the wrench in 'the nenel end ordinery mennen It willbe 'seen that 'the top surface .of the jawy is levela'nd horizontal, when the wrench isy in the position shown in the drawnee`,end. le rerelliel' with. elle serrated or toethed 'lower eurfeoe 19 of "the upper jew It will aleje be eeen drenthe rooting Portion 12 has shoulders. 2Q @nel 2lftornleel' et oorlo- Steslrle'efof elle fone-nerort-on' 13, these ellonldere; being 'd'elnoeeel inplenee entendng et 'an' eiigle'to'ealiptheri Furthermore, the
