Patent for a new and improved horse-detacher. This design "is to make a compound single-tree which, with certain attachments, will hold the traces securely or allow them to be drawn off the hooks if the horse should run; also, to hold up the shafts while the horse is passing therefrom" (lines 15-20). To this end, it consists in "[t]he combination, with the spring-held vibratory draft-rod having the loop, of the strap and the shaft, the latter carrying the oppositely-placed stirrup-arm and treadle-arm" (lines 74-78).
