The journals o! the-*shaft d of the-wheel D revolve in beds formed in the upper'ends of two perpendicular' bars, E E, rigidly attached to -the frame ofthe sulky.

l The wheel D is glwved in its rim for at least onehalt' of 'its circumference, and in this groove m-works the chain c.

To vthe lower part ofthe wheel D is pivoted a counesting-rod, h, whose other cud is pivotedfto the lever N near its fulcrum in lits lower end.

The seat K is attached to the upper part 'of the bar k by a pivot, aud the lower end of the bark is pivoted to the upper part of the end of the axle-tree, just wit-h` in theleft-hand wheel T `of the sulky.
