Description: |
| The compound is any of several tools such as a hammer, monkey wrench, or hatchet, with a partially threaded spur. To use this tool, embed the spur in solid wood, give the tool a quarter turn, & you have a solid hitching post for your team.
No mention of what using this tool would do to the solid woodwork.
A hammer fitting this description appeared on the June 14, 2008 mjdtools auction at Erie, Pa. A different one is shown on pg. 104 of Baird and Comerford's "THE HAMMER."
Canadian patent no. CA-33,896 corresponds to this patent; no. 460,094 refines the idea. |
