I've had a Daniel Cheney quick adjust wrench for a few years. I got it at a Browns Tool Auction along with 2 original patent documents. Cheney was issued patent 581,267 on April 27, 1897 and patent 611,771 on October 4, 1898. The first patent was for a quick adjust wrench and the second is for improvements on the same wrench design. The example wrench is built per the second patent design. This is believed to be a prototype wrench as it doesn't appear that the wrenches ever went into commercial production. The wrench was in one of my display cabinets because I never decided on how to display the patents along with the wrench. After completing the Hilary Klein cabinets I decided to build a similar cabinet that would hold both patent documents along with the wrench. Each patent document is enclosed in a Lexan sleeve that encases the patent document with only the very top of the sleeve left open so the patents can be removed if required. The sleeves hopefully are tight enough that the patents won't gradually sag in fall down inside the sleeves.
