SPECIFICATION forming part of Letters Patent No. 233,585, dated October 19, 1880,

Application filed August 14, 1880.

To all whom it may concern:

Be itknown that I, CHARLES It. WALK- LEY, of Ohurubusco, in the county of Whitley and State of Indiana, have invented a new and useful Improvement in Bob-Sleighs, of which the following is a specification.

My invention consists in a novel construction of the knee, and the combination and arrangement thereof with relation to the runner and the bolster, and of the runner with relation to said knee and to the draft-bar, whereby provision is made for enabling the runners of each pair to move independently of each other when meeting with an obstruction, and to work simultaneously when moving on a level surface; and, further, in a novel arrangement of the rear sled with relation to the frame or body of the sleigh, whereby provision is made for increasing or diminishing the distance between the front and rear sleds.

In the accompanying drawings, Figure l is a top view of a sleigh embodying my improvements. Fig. 2 is a side view of the same, partly in vertical section, through the line or w of Fig. 1. Fig. 3 is a transverse vertical section, taken in the line y 3 of Fig. 1. Fig. 4 is a transverse vertical section in the line 2 z of Fig. 1.

Similar letters of reference indicate correspondin g parts.

A represents the frame or body of the sleigh, which may be of any suitable description. B

- B represent the runners of both the front and rear sleds.

The front ends of the runners in each pair are connected together by a bar, 0, the ends of which abut against the inner sides of the runners, and are held in place by means of screws 0, passing through tapering holes in the runners and into the ends of the bar.

To the bar 0 of the front sled is attached a draft-pole or tongue, D, to which the team is harnessed.

To the bar G of the rear sled is attached a frame, E, on the top of which is a staple or keeper, j, and on the top of the bar is a similar staple or keeper, f Through these two keepers passes the rear portion of a reach or perch, G, the front end of which is hinged to a cross-bar of the frame or body A. The rear (Model) portion of this reach is provided with holes, through which, and through the keepers f f pass bolts g, which hold said reach in place.

The longitudinal rails of the frame or body A pass through slots in a rib or bar on the top of the bolster M of the rear sled. By means of these rails and the reach Gthe rear sled is connected to the frame or body A.

By removing the bolts g the rear sled may be moved nearer to or farther from the front sled, as the reach G will slide in the keepers ff and the rails of the frame will slide in the slots in the bar on the top of the bolster M, and said rear sled is held in place by means of the bolts, as before described.

The runners B B are connected to the bolsters M by means of knees constructed as follows:

H represents a flat iron bar, bent midway of its length to form an eye, h, below which the ends of the bar diverge and are secured to the upper surface of the runner by screws or bolts.

H represents two diagonal braces, the lower ends of which are secured to the upper surface of the runners, and through the upper ends, and through the bar H, below the eye h, passes the rear end of a rod, K, the front end of which is attached to the bar 0, which connects the front ends of the runners.

H is a brace, the lower end of which is screwed or bolted to the inner side of the runner, and its upper end is formed into an eye, h.

J is a rod or bolt having a head on one end and at the other end a screw-thread provided with a nut. This rod or bolt passes through the eyes h and W, and through lugs 2', attached to the under side of the bolster, and by this means the runners are connected to the bolster.

By this mode of attachment the runner B is allowed to rise and fall and pass over an 0bstrnction or uneven surface independently of and without affecting the position of the runner B and vice versa, and both runners will move uniformly when passing over an even surface.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a bob-sled, the combination of the body A, bar 0, having keeper f hinged reach having eye 72, and the bolt J, passing through Gr, bolts g, frame E, having keeper f, and the bolster-lugs, all combined to connect'the runslotted bolster M, as and for the purpose dener and bolsters, as shown and described. scribed. CHARLES R. WALKLEY.
