Abstract: This invention relates to improvements in wood-chopping axes, whereby it is designed to provide an improved construction of axes, with removable bits, for the substitution of others, when. worn too thick and blunt for use. The invention consists in making ,the polls in two parts, divided in the plane .of the cutting-edge, and shaped so that when put together and joined by rivets; a groove will be formed, dovetailed at the base, for holding the bits, which are fitted to it, so that a part of the rivets will pass through the tongues fitted to the said grooves. Claim: Axe-polls, constructed in two parts A, shaped and secured as described, and the bits, joined thereto by a tongued and grooved connection.

Manufactured by E. & T. Fairbanks & Co. - St. Johnsbury, Caledonia County VT

Abstract: We have made certain Improvements in the Machine for Weighing Heavy Bodies in addition to those formerly made by us, and for which we obtained Letters Patent bearing date the 13th day of June, 1831 (Patent #6573X); and we do hereby declare that the following is a full and exact description of our said improvement, reference being had to the drawings which accompany this specification and make part of the same; and we do further declare that in these drawings and this description we have represented and described many parts which are common to other machines for the same purpose and are found in that patented by us as aforesaid, which we have done for the purpose of more clearly explaining those parts which we believe to be new and of our own invention, and which are distinctly set forth in the claim hereunto appended. Claim: The variation in the manner of connecting the two levers in the center, (whether they be composed of one or more parts each,) to wit: by means of knife-edges resting in pendulous rings or circles, as shown in drawing No. 1, letter K, and drawing No. 2, Fig. 6, and Figs. 3 and 4.

Multiple jaws, including ability to reach countersunk nuts, and grip pipe and similar round objects. The pipe gripping jaw insert sets on a spherical base. Adjustment for the movable jaw is a screw extending to the end of the handle. Corresponding Canadian patent CA-38,492 was granted March 15, 1892. In function and overall appearance, this design is similar to the "Tryon Wrench" (patent no. 667,143). An unmarked combination tool appearing to match this patent is known; a comparison to the TRYON tool demonstrates several differences. This patent improved by Hussey's May 24, 1892 patent (no. 475,450). A wrench marked with that patent date has head and jaws more closely resembling this patent's design. The NIAGARA WRENCH COMPANY was incorporated at Albion, NY in December, 1892 under the laws of West Virginia in relation to the Hussey patents.
