mannen a A 'fifth wheel E,is also provided, so that the` forward' runners may have per-` fect freedom to turn, in the manner `com-' monto all vehicles. i i a rolling bolsters M', M between which and fixed` bolsters M,` M, the friction rollers H, H, intervene, the latter being held in their places by the sprngs H, H', which are i fastened in their Centers to the top of the hindaxletree C.

The "forwardends of the hind runners u i The hind runners D, D, are provided with a D, D, are securedto the reach P, by means j of braces L, These runners are also furi ther braced by the nner braces K, K, which extendgfrom the forward ends of the run- "ners, back to clip I, on the aXletree C, where they *fasten'- t\ The olling` bolsters M M are fastened totheaxletree C( Owing to the necessary stiffness of'the connection ofthe ,front ends 'of thehind runners with the reach P, by the braces L, there could be no independent movement of the hind runners without i 'wrenching the sleigh, unless means were provided for a slght movement of the aXletreeC, incorrespondence with the movements of either of the runners D, D. The `arrangement of the rolling bolsters M M and friction rollers H, H, permit this movement of the aXletree, without in the least imparing the stability of the hind runners or any other portion of the sleigh. When the forward end of runner D, is thrown up as in Fig. 2, the hind axletree C, slides back a little; when the forward end of the runner is thrown down, the aXletree moves correspondingly forward. In this manner `I construct adouble runner` sleigh having greater fleXibility in all its parts, yet of less weight, but more proportionate strength, than any vehicles of the kind ever before made. The cost of construction, in proportion to weight and size, is less, for my improvement than the ordinary sleigh.

"The fiexibility of my sleigh destroys none of its strength, it being capable of sustaining a given burden with equal `firmness, whether running over a smooth` or rough road. Its great fiexibility andfreedom from racking also relevesit from sudden arrng or thumping motions, rendering it much `more agreeable as a passenger vehicle, than the ordinary sleighs. i v

Having thus described my nventon, I O, which permt the movement of the forclaim, ward runners, without any Wrenchng.
