Description:
My invention relates primarily to an improvement on the subject matter of Patent No. 733,648 granted to me July 14, 1903, for chain tongs, though my present improvements are not necessarily limited to use with the particular construction for which that patent was granted.

One of my objects is to provide a construction whereby the slack of the chain in adjusting the wrench on the article to be gripped preparatory to operating the tool shall be taken up to the fullest possible extent thereby to adapt the jaws to engage the article between their ends.

Another object is to provide a construction in which the free end of the chain may be readily disconnected from the wrench.

In 1924, the IDEAL CHAIN WRENCH with flange adapter was advertised by BRUNSWICK-KROESCHELL with offices in Chicago and New Brunswick, NJ.
