WILLIAM LOUIS BESSOLO, 0F SAN DIEGO, CALIFORNIA` QUICK-ADJUSTABLE WRENCH.

Specification of Letters Patent.

Patented Oct. 28, 1919.

Application led May 6, 1919. Serial No. 295,046,

sion is made for various adjustments, myl

object being the provision of a strong powerful and durable wrench which will at the same time be compartively simple and inexpensive.

These objects I preferably carry out` by means of a construction which I will now describe in connection with the' accompanying drawing, forming a part of this specification, and wherein Figure 1 is an elevation of my improved wrench, the handle portion of which is partly broken away and in section.

Fig. 2 is a vertical longitudinal section through the upper portion of the wrench;

Fig. 3 is a horizontal section taken substantially on line 3 3 of Fig. 2, and

Fig. 4 is a similar View taken substantially on line 4-4 of Fig. 1.

eferring now to these figures, my invention proposes a construction in which both of the engaging jaws l0 and 11 are adjustable, and in which a rigid shank 12 is securely connected by rivets, bolts, or other fastening means, at one end to an adjusting bracket 13 in a recess of which is seated a milled nut 14 'engaging the threaded portion 15 of the shank 16 of the' jaw 10, which shank extends through conformable openings of the bracket 13, so as to thus adjust the jaw l0 with respect to the jaw 11.

The bracket 13 has an opening at one side parallel to the shank 12 through which a second shank 17 extends, this shank projecting parallel with the main rigid shank 12 and being pivotally connected at 18 at its outer end to the movable jaw 11, so that by shifting the movable shank 17 longitudinally, the movable jaw 11 which has a sliding connection upon the shank 16 of jaw 10, may be adjusted toward and away from the latter jaw.

The other end of the main rigid shank l2 is extended longitudinally through a handle 19, to which it is secured by rivets or bolts, lor other fastening members, at 20, theV extremity of said fixed shank 12 projecting beyond the handle as seen in Fig.

1, and being threaded as at 21 for the reception of a knurled adjusting nut 22.

The handle 19, like the adjusting bracket 13, has a longitudinal `opening parallel to the shank 12, through which the movable shank 17 extends, the extremity thereof normally projecting slightly beyond the inner end of. the handle and into the path of movement of the nut 22 longitudinally of the shank 12, so that when the nut is screwed inwardly upon the threaded portion 2,1 of the rigid shank, it will engage the free end of the movable shank 17 and shift the latter and the movable jaw 11 toward the jaw 10.

Thus in applying my improved wrench to an object, the jaws are first adjusted so far as possible to the size of the object, through the adjustment of the jaw 10 and the turning of the adjusting nut 14 for this purpose, and when adjusted to approximately the size of the object, the operator may create the desired pressure upon the obj ect by turning the nut 22 which will force the j awy 11 toward the jaw 10, and thus into snug pressure against the object.

It is thus obvious that my invention provides for the ready adjustment of both of the jaws and includes a strong durable arrangement which will be at once simple, inexpensive and eiiicient in use.

I claim:

1. A wrench having a main fixed shank threaded at one end and provided with a laterally projecting bearing at its opposite end, a movable shank adjustable through said bearing and parallel to the Vmain shank, a jaw carried by said movable shank, a second shank adjustable through said bearing and extending parallel with and along the main shank, a jaw carried by said last named movable shank and opposing the first jaw, an adjustable nut in the said bearing of the main shank for ,adjusting the first mentioned movable shank, and a nut screwing on the threaded opposite end of the main shank and engaging the free end of the second movable shank as described.

2. A wrench comprising a main fixed shank, a pair of movable Shanks paralleling the main shank at relatively opposite sides thereof, jaws carried by said movable shanks, a bearing at one end of the main shank through which the movable shanks are extended, an adjusting member supported in the bearing for adjusting one of the movable shanks, the other of said movable Shanks extending for approximately the full length of the main shank and means adjustable at the relatively opposite end of the main shank and engaging the adjacent end of the last mentioned movable shank to adjust the latter. 4

3. A Wrench having a main xed shank rovided with a handle at one end beyond which the adjacent extremity of the shank projects and is threaded, said handle having a longitudinal opening paralleling the main shank, a jan beyond the opposite end of the said shank, a second javv movable With respect to said first jaW, a shank connected to said second jaw and paralleling the main shank and extending through the said handle opening, and an adjusting nut upon the Y threaded portion of the main shank for engageinent with the free end of the shank of said movable jaw, for the purpose described.

4. A Wrench having a main ixed shank provided with a handle at one end beyond which the adjacent extremity of the shank projects and is threaded, said handle having a longitudinal opening paralleling the main shank, a j aiv beyond the opposite end of the said shank, a second jaw movable with respect to' said first jaw, a shank connected to said second jaw and paralleling the main shank and extending through the said handle openino', an adjusting nut upon the threaded portion of the main shank for engagement with the free end of the shank of said movable jaw, said main shank having an adjusting bracket adjacent to the movable javv, a shank with which the first named jaw is rigid, extending through the said adjusting bracket and provided With a threaded portion, and an adjusting nut supported by the said adjusting bracket and engaging the threaded portion of the last named shank, for the purpose described.
