J. J. SANDS. WRENCH. v APPLICATION FILED DEC. 8. I913. 3 1 L D. A d .w H .w a P Attorneys THE NORRIS PETERS 60., PHOTO-LITHQ. WASHING TON. D. c JOHN J'. SANDS, 0F STANLEY, NEW BRUNSWICK, CANADA. WRENCH. Application filed December 8, 1913. To all whom it may concern: Be it known that 1, JOHN J. SANDS, a sub ject of the King of Great Britain, residing at btanley, in the Province of New Brunswick, Canada, have invented certain new and useful Improvements in Wrenches; and I do hereby declare that the following is a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same. The invention to be hereinafter described relates to wrenches. , In order to more clearly disclose the construction, operation, and use of the invention, reference should be had to the accompanying drawings forming part of the present application. Throughout the several figures of the drawings like reference characters designate the same parts. In the drawings: Figure 1 is a plan view of the wrench, with part of the handle broken away to show how the catch is operated; Fig. 2 is a side view of the same; Fig. 8 is a side view of the inside ratchet ring and collar; Fig. 4 is a plan view of the same, with the movable blocks removed; Fig. 5 is a detail plan view of one of the movable blocks; Fig. 6 is a front view of the same; and Fig. 7 is a detail of one of the adjusting screws. The main objects of the invention are, to produce a strong, durable, and easily operated wrench, which can be produced at a relatively low cost, can be used for either square or hexagonal nuts, and which can be adjusted to it nuts of diiferent sizes. Referring to the drawings in detail, 1 designates the handle, to each side of which, near the inner end thereof, there is secured a tapered piece 2, integral with a ring 3 provided at its front edge with an inwardly turned flange 4. The two rings 3 are secured. together at their outer sides by means of a screw 5 threaded through alined lugs 6, integral. with the rings. When secured together the rings form an inner annular chamber, between the flanges, in which is mounted a ratchet ring 7 pro ided with front and rear lower integral collars 8, which extend outwardly therefrom so as to be flush with the outer faces of rings 3. Tn order to rotate rings 8 in any desired direction, a catch 9 is pivotally mounted be tween the tapered pieces 2, and adapted to Specification of Letters Patent. Patented Apr. 13, 1915. Serial No. 805,273. engage the teeth of the ratchet ring 7. Catch 9 has its outer end recessed to receive the inner end of a bent spring 10, secured in handle 1, and so bent that when the catch is turned to either side, so as to engage the teeth of the ratchet ring, it will retain the catch in position, as in Fig. 1. By this means the ratchet ring may be locked against rotation in one direction, while the handle and rings 3 are free to be rotated in the other direction; for a purpose to be later disclosed. At each side of the collars 8, at the front and rear thereof, there are secured pieces 11, the front ones of which have their inner edges out out, to form part of a hexagonal form adapted to receive a nut. Between pieces 11 blocks 12 are slidably mounted. These blocks have their outer faces produced so as to be flush with the outer faces of pieces 11, and are cut out in their front faces, in a spread V shape, as at 13, so as to form with the pieces 11 a hexagonal gripping socket. The main body of blocks 12, below the front pieces 11, is cut out at a sharper ll, as at 14, and the rear pieces 11 are out out in V shape as at 11*, so as to form with the blocks a square gripping socket, for square nuts. In order to adjust the wrench, the blocks 12 are made adjustable. The extended sides of blocks 12, which are slidably mounted between pleces 11, are provided with threaded bores 13 adapted to receive adjusting screws 14, which have their end portions oppositely threaded. The ends of screws 14 are tapered and toothed. A toothed wheel 15 is rotatably mounted on one side of the ratchet ring 7, and is in mesh with the toothed end of the right hand screw 14. The other end of this screw is in mesh with the toothed tapered end of a spindle 16 rotatably mounted in a block 17, secured in'the ring 7. The other end of spindle 16 is in mesh with the left hand screw, as indicated in Fig. 1. In order to permit easy and quick adjustment the screws 14 have their ends slightly recessed, and are mounted on hearing screws 18 threaded through the ring 7. By rotating wheel 15 the blocks 12, by means of screws 14 and spindle 16, may be drawn closer together or forced farther apart, as desired, to take nuts of difierent sizes; as will be evident. After gripping the nut, the ring 7, and consequently the gripping means, may be revolved in either direction desired by means of catch 9, and handle 1, as previously explained. It is thought that the construction, operation, and use of the invention will be clear from the preceding detailed description. Changes may be made in the construction, arrangement, and disposition of the several parts of the invention Without in any Way departing from the field and scope of the same, and it is meant to include all such Within this application wherein only a preferred form has been disclosed. Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent is: 1, In a device of the character described; inwardly flanged rings, secured together; a ratchet ring mounted therebetween; means for revolving the rings in one direction, independently of the ratchet ring; means for revolving theratchet ring; pieces secured at each side of the ratchet ring, at the top and bottom thereof; gripping blocks slidably mounted therebetween; and screw means foradjustingthe gripping blocks. 2. In a device of the character described, inwardly flanged rings secured-together in such a manner as to form an inner annular chamber; a handle; tapered pieces integral With said rings and secured to the inner end of said handle a ratchet ring loosely mounted in the chamber between the sald rings; a catch plvotally mounted between the said tapered pieces and adapted to engage the catch in engagement with the said ratchet ring; front and rear pieces secured on the front and rear of the said ratchet ring, the front ones of which are adapted to form the diametrically opposite sides of a hexagonal gripping form, and the rear ones of which are adapted to form the two opposite corners of a square gripping form; blocks slidably adjustable between the said front and rear pieces and adapted to cooperate with the said front pieces to form a hexagonal gripping form, and with the rear pieces to form a square gripping form; and means for adjusting said blocks. 3, In a device of the character described, adjusting I means, comprising; slidably mounted blocks, screws threaded therein and having their, ends oppositely threaded, the ends of the said screws being tapered and toothed, a rotatably mounted toothed wheel in mesh with one end of one of the screws, and rotatably mounted spindle having one end in mesh with the other end of the same screw and the other end in mesh with one end of the other screw. i In witness whereof have hereunto set my hand in the presence of two witnesses. I, JOHN J. SANDS. Witnesses; JASQFT. SHARKEY, VVILLr M W. HEA D. Copies of this patent may be obtained for five cents each, lpy addressing the Commissioner of iatents, Washington, D. G.
