John George Mole |
Batavia, IL |
See also Canada patent 6,821. The Mole Tire Shrinker was very popular and was available through the Sears and Montgomery Ward catalogs until at least 1919. The three manufacturers listed are just the three that we know of; there are likely quite a few more. More research is need to determine who used the patent while it was still in force. |

Clevis for Plows
|
Lewis A. Weyburn |
Rockford, Winnebago County, IL |
Abstract:
The object of this invention is to produce a combination-clevis, and to attach the same to a plow-beam in such a manner that a doubletree and singletrees connected therewith and supported thereby will not drop down upon the heels of draft-animals hitched thereto whenever said animals turn at an angle with the plow-beam or materially lessen the draft thereon.
Claim:
The combination, with the series of devises herein shown and described, of a pair of draft-plates connected therewith by means of a pin, C2, and a double hook, B, for maintaining said series of devises in a substantially horizontal position, and thereby preventing a doubletree, G, and singletrees connected therewith from coming in contact with the heels of draft-animals. |
