Description: Patent for a new and improved spring-draft attachment. This design "is to do away with the ordinary doubletree . . . which is especially adapted for a two-horse vehicle, which . . . prevents the horses from pulling against one another, [and ] prevents the pole from swaying sidewise" (lines 10-18). It "consist[s] of a frame provided with an eye at one end and with a cross-bar near its center, a draw-bar having one end screw-threaded and provided with an eye at its other end and with a collar at its screw-threaded end, a nut on the draw-bar, and a spring surrounding the draw-bar" (lines 65-71).
