This invention relates to certain new and useful improvements in coaster sleds, and has more particular reference to a device of this kind adapted to be propelled by the action of the occupants feet upon the surface over which the sled. travels. v

A principal object of the invention is to provide a coaster sled of the above kind which may be readily used for coasting onthin crusts of ice and snow and upon snow which is quite dee, by the provision of relatively long and broad runner shoes.

Another ob ect is to provide a coaster sled of the above kind embodying a plurality of longitudinally tiltable runner shoes whereby the sled may. pass over irregularities of the surface upon which it travels, with a minimum amount of vibration or Still another objectof? the invention is to generally simplify. and improve devices of the above be extremely simple and durable in con- With the above general objects in view,

and others that will become apparent as the nature of the invention is better understood, the same consists in the'nov'el form, combination and arrangement of parts, herein-' after more fully described, shown in" the accompanying e drawings, characters indicate throughout the several views,

Fig. 1 is a side elevational view of a coaster sled constructed in accordance with drawings and claimed:

' wherein like reference 1 the present invention.

Flg. 2 is a top plan view of-the device shown in. Figure 1-. v

Figure 3 1s a transverse action taken substantiall upon line3-3 of 1, and partly bro en away. 1 f'" Figure at is a view similar to Figure 3 taken substantially upon line 44 of Figure 1.

plan view of the deand Figure 5 is a bottom vice shown in Figure 1 Figure 6 is an inverted perspective view of one of the runner shoes.

Referring more in detail to the drawings, the present invention embodies a transverse supporting board 5, having outwardly and laterally projecting transversely aligned kind whereby the same will accomplished by providing corresponding parts lower end thereof. Journaled upon the axles 6 are brackets 7 whichare rigidly secured upon the intermediate portions of runner shoes 8, and it will thus be seen that the runner shoes 8 are pivotally mounted for longitudinal tilting movement relative to the board 5. The runner shoes '8 preferably consist of relatively broad and long flat plates having upwardly curved forward ends, and by reason thereof it will be readily seen that the runner shoes will effectively remain upon the surface of deep snow or the like. Any suitable means, such as cotter pins 9, taining the brackets 7 on the axles 6, and in case it is desiredthat the sled should travel comparatively fast the shoes 8. may be promay be provided for revided with central longitudinal ribs 10 upon the under surfaces thereof, the ribs 10 being preferably of metal-,to provide for reduction of friction.' However, as the sled may be manufactured in relatively small size for the use of younger children, it may be desirable to make provision for preventing too speedy travel of the sled, and this may be grooves in the under surfaces of the shoes ribs 10. i y The deviceembodies a seat board consisting of arelatively'broad rear seat portion 11 and-a relatively narrow forward portion 12, the seat portion 11 being disposed upon the upper edge of the transverse supporting board 5 and rigidly secured to the latter. Angular braces are preferably employed as at 13 for connecting the seat portion of the seat board to the transverse supporting board 5, whereby the latter is braced againstlongitudinal strain. Also, the seat portion ll of the seat board may be formed relatively long as shown in two q'cupants may be accommodated. Jo aled in the forward end of the narrow 'o'rward portion 12 of the seat board is a vertical steering post 14 to the lower end of which is pivoted a runner shoe 8 similar to the shoes 8 The steering Post 14 is held against longitudinal displacement or properly related to the seat board by the provision of thrust collars 15 on the steering post above and beneath said seat board. The bracket 7 is rigidly secured upon the runner 8 and is lower end of the steering post 14, the latter being pivoted between the bifurcations of the bracket 7? by means of a transverse 8 instead of the Figs. 1 and 2 so that bifurcated to receive the pivot pin 16. The front runner shoe is thus also mounted for longitudinal tilting movement, and for facilitating guiding of the 'sled the upper end of the steering post 14 a second occupant may be seated upon the rear end portion of the seat portion 11 of said seat board. The occupant upon the forward part of the seat portion 11 may thus employ hiscfeet for action upon the surface over which the sled travels, so as to cause the'traveling movement of the sled.

From the foregoing description it will be seen that I have provided a simple and durable form of coaster sled which may be readily steered by the occupant and which will pass over irregularities of the surface upon which the sled travels with a minimum amount of vibration and jolting. It will further be seen that it is not necessary to have ice or tightly packed snow before the. sled can be used as the broad runner shoes or plates will provide for supporting the occupant on the sled upon the surface of deep loose snow having only a thin crust.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

1. A coaster sled including a seat board, a transverse vertical supporting board secured to the under side of the seatboard near the rear end of the latter, an upright steering post journaled through the forward end of the seat board, a thrust collar secured on' the steering post against the lower side of the seat board, a transverse horizontal between its ends against the rear side of the steering post and against the underside of the thrust collar, axles rigid with and projecting laterally from opposite sides of the lower end of the supporting board, and runner shoes pivoted on the axles and the lower end of the steering post for longitudinal tilting movement.

' 2. A coaster sled including aseat board,

a transverse vertical supporting board secured to the under side of the seat board near the rear end of the latter, an upright steering post j ournaled through the forward end of the seat board, axles rigid with and projecting laterally from opposite sides of the lower end of the'supporting board, and runner shoes pivoted on the axles and the lower end of the steering post for longitudinal tilting movement, said runner shoes comprising relatively broad elongated plates having flat rear portions provided with central longitudinal ribs on their under surfoot rest and steering bar rigidly secured faces and formed with upturned forward ends.

In testimony whereof I afiix my signature.
