Log-Carrier.

Patent for a log-carrier with an improved construction from a previous patent (No. 539,380).

It also maintains "a uniform leverage without the use of guide-rollers or other means" (lines 54-56), and balances the sliding tongue so that "the team is relieved of the weight thereof" (line 62).
