| Munn & Co.- patent attorneys
The object to the invention is to construct a wrench especially adapted for removing nuts from vehicle-axles in such manner that the nut need not at that time be grasped by the hand, thus preventing the fingers of the hand from becoming soiled. Another object of the invention is to provide a wrench through the medium of which a nut may be quickly and conveniently removed from or placed upon the vehicle-axle and whereby the wrench will be capable of starting the nut no matter how fast it may be secured, and to screw the same securely to a bearing. A further object of the invention is to provide a wrench whereby after the nut has been loosened it may be expeditiously and conveniently removed from the axle, or wherever it may be placed, without swinging or moving the body of the handle of the wrench. -- from the specifications.
The "pivot" for the socket is in an oval hole, so the toothed portion on the back of the wrench can engage or disengage from a spur on the wrench handle.
Corresponding Canadian patent no. CA-53,058 was issued August 1, 1896.
Known examples are malleable iron marked SHAFER BROS SAN BERNARDINO CAL // PATENT APPLIED FOR. or SHAFER BROS SAN BERNARDINO CAL // PATENT JUNE 9, 1896
