To ALL WHOM IT MAY ooncnnn:

Be it known that I, BJARNE TIlOMPSON, of the city of Chicago, in the State-of Illinois, have invented a. certainnew and useful Improvement in Sleighs; and I do declare that the following is a full, clear, and exact description'of the construction and opei-ation of the same, reference being bad to the accompanying drawings,

I making a part of thisspecification, in which- Figure 1 is a side elevation. Figure 2, a front elevation.

Figure 3, a detached view of iron, d. I l

The object of my invention is to provide a device, by means of which the whole'body of a sleigh, when placed on springs, may have vertical'inotion, and be prevented from moving laterally or longitudinally.

To enable others skilled in the art to make and use my invention, I proceed .to describ'e'its construction and operation. 7

The runners A, the body B, and the springs C, may be constructed in any of the known forms. In the dash-board D, I place two slots, at, enlarged at, the top, which slots should be properly secured and strengthened ,by suitable irons; or, if desired, these slots. may be made in therunners, the same being well turned up in front, and made broad enoughfor the slots. These slots are vertical, about sizi inches in length, and in width to be adapted to the irons they are to receive; and the location ofthe slot must depend on the form of the sleigh and the location of the irons, d. To the body of the sleigh, and in front, Iflfirmly attach two irons, d, one on each side, the same being bolted or otherwise fastened to the sleigh. These irons are provided with a head, and when attached to the sleigh, they project forward far enough to'allow the head of the irons to pass through the slot, when the body of the sleigh is in place, leaving a little space=between the frontot the sleigh" and the dash-board or runners, so that the sleigh can move vertically with the action of the springs.

The foregoing description is especially adapted to sleighs having a dash-board separate fronithe body; but" when the dash-board forms a part of the body of the sleigh, and is attached thereto, the slots must be in the runners, and such other appropriate changes must be made as will readily suggest themselves to a mechanic.

It has not hitherto been found advisable to construct sleighs with springs, because the body of the sleigh being, in front, rigidly attached to the runners, has interfered with the action of the springs.' My device over-1 comes this difiiculty. The sleigh having been constructed as described, the body is brought to its place-by passing the ends or heads of the irons, (I, through the enlarged parts of the slots, and there may be secured t6 the springs in the usual manner. The body of the sleigh, notbe'ing rigidly attached in front to the runners, isfree to be moved vertically by the action of the springs, while the irons (1, being provided with heads, and

workingin the slots, will not permit lateral or-lorigitudinal motion. .The irons 11 may be constructed asshown in fig. 3, and bolted to the bottom of the sleigh, but, in form and structure, must be adapted to the kind of sleigh with which they are to be used.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is" Connectio the body of the sleigh with the front or runners, by means of the slots at and irons d, con:

structedsnd ogcrating substantially as, specified. i
