'Be Vit known" that'fI, lowivsov- HAND, a citizen ofthe United States, and a," resident of Orlando, in the county of Orange and State'of Florida, have inventeda "certainl new anduseful Improvement inl/Vrenches,

. of what aiefouojwing is a Specification- My present `'invention relatesgenerally to wrenches and more particularly'to a Wrench 'Y having something of, Ythenature ofa combination tool,y in that it, is" particularly adaptable to round surfacesjfsuch 'a5 pipg and also to polygonal shaped work. i Theobject of myinvention is to provide a Wrench which vmay be instantly adapted 'to practically any lr-indj ofw'oi'i'ky, `which w'illbe` extremely simple', rspeedyfi'n itskac'tionfand so arranged'that any piece or part may be made or adjustedat any tune.y

Further objects of my invention Willjbek plainly understood from" the following description in which reference is madeto the accompanying draivingsforming a part of this specification and in Which-f .n

Figure l is a side elevation illustrating the practical applicationof mywrench to round Worin F ig. 2 is aL longitudinal section therethrough in open yposition,,and L,Fig Buis an edge vieu7 looking toward the lekftkin Fig. 2. f

Referring now toftheseiigures, my improved Wrench includes a handle A having a series of teeth Af at one end, and projecting at one side, whereby to constitutea rigid jaw A2, the handle A having also a slot A3 extending therethrough at the inner end of the rigid head A2' formed as described, the' inner portion of Ywhich head, at the sideopposite the teeth A', is provided Witha rearwardly presented edge A4', thus located at the forward end of the slotA3 for a purpose to be hereinafter described.r At an intermediate point, and at the inner end of the slot A3, the handle A is provided with a lateral extension A5, having a slot A6 therethrough, and having a grooved outer surface as seen at A7, the groove forming a seat for i one portion of a U-shaped spring B as most Y plainly seen in Fig. 2.

The movable jaw. C which yis 'provided along its inner surface with teeth C and which is adapted to'opp'ose the rigid jaw A2 at the .outer-end' of the handle A, Vhas a'laterally extending shank C2 atxits'inner end,

which shank extendgthrough the slot A3` of the handle before mentioned, and 'is pro- Specification of Letters Patent i vided alongfits outeredgeyvvith a series-off teeth C3., with Vwhich the i v,sented edge A? before mentioned is adapted for engagement in selected adjustment, the

of theflever Dr ,toward the-handle Aas Will be seen by a comparison of Figs. .l and 2.

It Vis obvious-.therefore that a Wrench so constructed Will be simple, cheap and durable, may be instantly applied with equal Vfacility to round andpolygonal'vvorlr, will promote instant release from the object be-` f ing acted'upon lby the Wrench, upon therelease of pressure upon the handle of the lever D, and may lbe'speedily adjusted to vary thefparticular 'relative spacing of the movable and fixed jaws.
