Y To all wlom'z't" may concern:

' Be it'jknown that I, DAVID fWr'enches,

"fication e 'more Larnaca@V A G. KENNEDY, a citizenV of the `United States, residing at Garyville,` in' the county of `lVashington 'and Statefof Florida, have invented certain newand useful Improvements in. Ratchetof Which the following 1s a speel- This `invention relates `to Wrenches, and particularly to Wrenches of the ratchet type. n

`Theobject of the inventionls to provide a'Wrench of thisu character so constructed `as to remove or tighten a square or hexagonutvvithout removing thewrench at each .'turn.

Another object is to so construct a Wrench of this characterthat when placed in position: all that is necessary is to move the handle upor down to cause the nutto turn continuously in one direction.`

With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes'in the precise embodiment of the -invention herein disclosed may be made Within the scope of what is claimed Without 'de arting from the spirit of the invention.

n the accompanying drawings Figure 1 represents a side elevation with parts broken out of a wrench constructed in accordance with this invention.

Fig. 2 is a transverse section ktaken on the line 2-2 of Fig. 1.

Fig. 3 is an edge view of one of the dies used in connection with the Wrench.

and thus detachablysecure the hinged section in closed operative position.

g The sections 2 and f3 form a circular head Which is provided With side flanges 7 designed to retain the removable die as 10, in position. Any desired number of these dies may be supplied with each Wrench, said dies having sockets of different `configuration ti" adaptvthem for use with diderent shaped nuts and which are interchangeable for this purpose. The dies 10 are each constructed of hingedly connected sections 11 and 12, 'the free endsy of which are united bya spring pressed latchf13 carried 'by one of the sections and engaged Witha pin 14: carriedby the other. This die 10 has an annular centrally disposed extension 15 arranged around the periphery thereof 'and provided with Anotches 16 which are designed forinterlockingengagement with a pawl 8 housed' in a chamber 9 of the `handle 1 as is shown clearly in Fig. 1. This paWl 8 is here shown Y-shaped in form and one side or the' other of the stem or shank thereof is engaged by a spring pressed tooth 17 mounted in the `handle 1 and yieldably held in engagement with said stem to hold one of the fingers 8 of the pawl in engagement with the notches of the die 10 according to the direction it is desired to turn the die so that when the handle 1 is oscillated a continuous'rotary motionwill be imparted to thedie.

The die 10 has a nut receiving socket formed therein which is here shown rectangular inform, although it may be of any other suitable or `desired configuration according to the configuration of the nut in connection with which it is to be used, said Wrench being especially designed for use on square andhexagonal nuts j To adapt a single die for use in connection with nuts of varying sizes, but the same configuration, an adjusting element or slide 18 is mounted at one corner of the die as is shown clearly in Fig. `1 and which is preferably constructed in the form shown 1n Fig. 5, having a flange 19 extending along one side thereof at right angles' thereto and toothed as shown at 20, said teeth being designed to be engaged by the threads of a thumb screw or worms 21 operable to project or retract the slide. The inner end of the sliding member 18 has a V-shaped notch 22 formed therein to receive one corner of the nut, the remainder of the nut being forced against the opposed Walls of the nut socket in the "die of operati-'l ing to adjust the niemberlraocoding to fthes'ize of the nutin-eonneetionwvitlifwhich the Wrench is to be used.` Itwillthus'be seen that a single die 10 may beusedoi screwing or unsorewing a number vof nuts of' diiierentsizes aiidfof the same coniguifat'ionbyV Simply adjusting thefslde .1%. @suitably reduce the size of the Opening'in thedieu 10 tuated.k
