Description: |
| "In the manner of mortising and making tenons on the ends of the spokes of wheels, panel work, cabinet work, joiners' carpentry, coaches, wagons, gigs, and to all other purposes where a square or quadrangular mortice and tenon have heretofore been used". The Journal of the Franklin Institute said of this patent, "The plan proposed is to make round tenons, by means of a hollow auger, which will form the tenon by boring. Two or three such tenons may be formed side by side, and corresponding holes be bored to form the mortise. When spokes of wheels are to be put into cast iron hubs, the holes are to be cast larger at the bottom than at the top, the mortise split, and a wedge loosely entered, which, in driving the spoke, will spread the tenon, and cause it to hold firmly."No particular claim is made. Instruments similar to the hollow auger have been in use from a remote period, and as no particular structure, or indeed any structure, of the auger is described, the patent, of course, is not for this; for what it is, we must leave others to determine." |
