Description

June 29 1926.
E. Y. SCOTT COUPLING FOR TRACTORS Filed April 29, 1925 /v .NRS Wm/4 WM Q Y 3|k A /J is rotatable therein. The outer end of the core normally bears against the lead plate and a link or draw-bar 17 projects through l be pulled against the spring 10 and the the aperture of the lead plate into the core .or bushing and it is secured t0 the said core or bushing in any suitable manner, as by a cross pin 18. The draw-.bar with the bushing is rotatable in the tubular member and this affords a flexible connection between the draft rigging 19 of a tractor or the like and the tongue of the load, which permits the tongue to rotate or partially rotate independentlyv of the movement of the tractor and it will, of course, permit the tractor to tilt without imparting strain to the tongue. p
' It will be apparent from an inspection of the drawing that as a pull is exerted on the draft bar, the core or bushing will be drawn into engagement with the plate 12, and .through the rods 13 the follower plate will spring will be compressed. Should the load encounter an obstruction and be temporarily arrested, the spring will yield to cushion the effect of the arrested load, as has been explained.
I claim: v
1. In a coupling for tractors, a tubular member adapted to be attached to the tongue of a load, a spring encircling the tubular member near its end, an abutment for the outer end of the spring, a follower plate on the tubularV member engaging the rear end Y of the spring, a lead plate, connections between the follower plate vand the lead plate whereby the tension of the spring holds the lead plate in engagement with. the outer end of the ytubular member, an element within the tubular member bearing against the lead plate, and a draw-bar extending through the lead late and connected to the last mentione element.
2. In a coupling for tract-ors, a tubular spring, a lead plate in front of the tubularmember, means for connecting the leadvplate and the follower plate whereby tension of the spring holds the lead plate against the end of the tubular member, an el-ement within the tubular member bearing against the lead plate, and a draw-bar extending through the lead plate and connected'to the last mentioned element.
