R. MIKKELSON! Wretich. 7
No. 216,690. Patented June 17, I879.
NYPETERS, PHOTLLLTHDGRAPHER WASHINGTON a c UNITEDSTATES PATENT, orrrcn nasMus MIKKELSON, or LODI, WISCONSIN.
lM PROVEMEN'l' IN WRENCH Es.
Specification forming part of Letters Patent No. 216,690, dated June 17, 1879; application filed February 26, 1879.
To all whom it may concern:
Beit known that I, RASMUS MIKKELsoN, of Lodi, in the State of Wisconsin, have in vented a new and valuable Improvement in Wrenches; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawings is a representation of a top view of the wrench with the face-plate removed. Fig. 2 is a bottom view of the faceplate, and Fig. 3 is a perspective view of the bush. Figs. 4 and 5 are details.
This invention has relation to improvements in ratchet-wrenches; and the nature of the invention consists in a certain arrangement and novel construction of the parts of the wrench, as will be hereinafter more fully set forth.
In the annexed drawings, the letter A designates the metallic handle or body of the wrench, consisting usually of two sections, a a, screwed together. The section a has at its end an angular enlargement, I), hay ing in its end a notch, t, and in its sides other notches, '5, difi'ering in size from each other. They may consequently be used in connection with different sizes of nuts. These notches have each upon one edge a U-shaped flange, a, forming, with the notch, a rectangular shoulder, and again subdividing it, so that each notch is adapted for use in connection with two sizes of nuts. There being three of these notches, I am by this construction able to set up six different sizes of nuts.
The free end of section a is expanded laterally in oval form, and in this enlargement 0a is made a circular recess, d, having in its bot tom a concentric opening of less diameter. As shown in Fig. 1, this portion of the wrench is rabbeted, and is raised to a level with the remainder of the wrench by a removable faceplate, B, having in it, opposite to opening 6, a similar opening, e.
0 indicates a cylindrical metallic nut-seat, having a central exterior ratcheted'aunular rib, f. This nut-seat is inserted in recess d, and its ends fit snugly and have their bear ings in the openings 0 e aforesaid, so that it has free rotation relative to the handle in one direction. It is prevented from rotating in the opposite direction by means of a springactuated pawl, g, arranged in a recess, 9, near the junction of the enlargement and handle, and turning upon a projecting cylindrical stud, h.
Z Z indicate mortises,-iormeddiametrically opposite each other in the line of the long axis of the wrench, the one being situated at the extreme outer end of the Wrench, and the other at the junction of. the recessed enlargement and handle of the same, and being of oblong form.
The face-plate B has projecting from its under side the dowels j j, corresponding in form to the mortises l 1, respectively, and has a perforation, n, in which is received the end of the pawl-post h. These devices effectually hold the faceplate B against endwise or edge wise displacement, thus relieving the screws whereby said plate is secured to the body of the wrench from all undue strain. These screws pass through holes 5 in a stem, m, of the face plate into the handle, and simply serve to hold the said plate against lateral displace ment.
The opening to receive the nut in seat 0 may be of square, pentagonal, hexagonal, and other forms, and is provided with a metallic bush, 0, of corresponding form. This is usually of spring metal, and is cleft through at one side, as shown at p, Fig. 1. By compressing this bush it is readily inserted in the nutopeniu g, and is prevented from escaping therefrom casually by its reaction, which causes it to bind in the opening.
The bush 0 is provided at one end with a stop-shoulder, q, the object of which is to pre vent it from being thrust through the open ing of the nut-seat. These bushes are readily removed, and are of diiferent thicknesses, to adapt them to nuts of various sizes.
What I claim as new, and desire to secure by Letters Patent, is-
The combination, with the handle A, having oblong enlargement ac, provided with cylindrical recess (1, having circular concentric opening a in its bottom, forming the rabbet f, In testimony that I claim the above 1 have the ratchet-cylinder O, seated in said recess hereunto subscribed my name in the presence and controlled by a pawl, the pawl-post h, and of two witnesses. the opposite mortises l l, in the line of the longitudinal axis of the wrench, of the faceplate B, having dowels j j, fitting snugly in RASMUS MIKKELSON.
said mortises, and a perforation, 12, receiving WVitnesses: the end of the pawl-post and the retainer- EDWARD ANDREWS,
screws 5, substantially as specified. J. H. PALMER.
