Specification of Letters Patent.
Patented a as, rare.
Application filed April 25, 1913. Serial No. 763,590.
To all whom it may concern Be it known that I, EDGAR A. SPERRY, a citizen of the United States, residing at Miletus, in the county of Doddridge and State of West Virginia, have invented new and useful Improvements in Wrenches, of which the following is a specification.
The present invention relates to improvements in wrenches, and resides in the construction, combination and operative arrangement of parts set forth in the following specification and falling within the scope of the appended claim.
In the drawing: Figure 1 is an elevation of a wrench constructed in accordance with the present invention, Fig. 2 is an end view of the same, Fig. 3 is a section on the line 33 of Fig. 2, Fig. 4 is a section on the line 44 of Fig. 1, Fig. 5 is a detail perspective view of the slidable gripping member associated with the movable aw of the wrench, Fig. 6 is a sectional view on the line 66 of Fig. 1, and Fig. 7 is a detail longitudinal sectional view taken through the sleeve directly above the shank.
Referring now to the drawings in detail, the numeral 1 designates my improved wrench in its entirety. The wrench comprises a stationary head 2 having an angular shank 3 to which is secured a handle 4. The shank is substantially rectangular in cross section, and has teeth 5 on its opposite edges.
The numeral 6 designates the movable jaw. This jaw includes a housing 7 which is provided with a substantially rectangular bore or channel 8 whereby the said jaw (5 is received upon the shank 3, without danger of the lateral movement of the said jaw with relation to the shank. The housing 7 has its end, opposite its engaging face, or its head provided with a member 9 which extends toward the shank 3, and this member, or lug 9 is adapted to be received within an annular groove 10 provided upon a sleeve 11. The sleeve 11 is circular in cross section, and has its outer face milled, and the said sleeve has its bore threaded, as at 12, to engage with the threads 5 of the shank 8, and whereby the jaws 6 may be moved toward or away from the jaw 2. The bore of the sleeve 11 is provided with diametrically opposite longitudinally eX- tending non-threaded depressions 13, and when the said depressions are brought over the oppositely arranged teeth 5 of the shank 3, the said sleeve as well as the head 6 may be moved longitudinally of the shank with out necessitating the threads of the sleeve co-acting with the threads of the shank, as, for instance, when a quick adjustment is required.
The heads 2 and 6 are each provided with oppositely disposed engaging faces, the faces upon one of the sides of the wrench belng flat to engage with flat elements, such as the opposite faces of nuts, etc., and the diametrically opposite engaging face of the head 2 is curved, as at 1 1, while the adjacent face of the head 2 is beveled, as at 15. The beveled portion of housing 7 has its sides provided with a suitable opening for the reception of a removable pin 16, and this pin is adapted to play in inclined slots 17 provided in the side walls 18 of a toothed gripping member 19. The gripping member has its inner face beveled, as at 20, to correspond with the beveled face 15, and the pin 16 serves as a guide for the member 19. It will be noted that when the member 19 is forced outwardly of the jaw 6, its upper toothed face will be arranged below the plane of the engaging face of said jaw, and should a pipe or the like he engaged between the inner curved face 14 of the jaw 2 and the toothed face of the gripping member 19, a rotary movement of the wrench will cause the gripping member to move inwardly of the jaw toward the bore of the shank. The said movement will raise the gripping member and so cause the same to more tightly engage with the element gripped between the jaws.
From the above description, taken in connection with the accompanying drawing, the simplicity of the device, as well as the advantages thereof, will, it is thought, be perfectly apparent to those skilled in the art to which such inventions appertain without further detailed description.
By reference to Fig. 7 of the drawings, it will be noted that the teeth 5 of the shank 3 have their ends beveled as are also the ends of the teeth or threads of the sleeve 11, but at opposite inclinations to those of the teeth or threads 5. This arrangement permits of the co-acting engagement of the teeth regardless of the position of the sleeve with relation to the shank.
Having thus described the invention, what I claim as new is:
In a device of the class described, in com bination a shank, stationary heads formed at one end of said shank and having a portion projecting slightly outwardly of the longitudinal edge of the shank and perpendicularly thereto, said head being formed in a plane with said projecting portion with a concave edge adapted to form a hookshaped jaw, a longitudinally slidable jaw.
mounted upon said shank, said stationary and slidable jaw respectively being formed with contacting edges perpendicular to said shank and in line with the projecting portionrof the stationary jaw, said movable jaw being formed opposite to said concave edge with a beveled edge extending vertically thereon, said movable jaw having a ledge disposed, transversely and in advance of the lower end, of said beveled edge, said ledge providing a shoulder adapted to. contact withthe projection formed upon said head, 7
copies of this. patent may be obtained for oppositely disposed pins carried by said movable jaw, a gripping member having an inner beveled face adapted to contact the beveled edge of said jaw and to rest upon the ledge, said gripping member having a EDGAR A. SPERRY.
