2 Claims.

A more specific object of the invention is toy provide a snow vehicle having a large snow bearing surface but one in which, when ridden, the line between stability and lack of stability is more finely drawn than it is in snow vehicles heretofore known. When drawn by hand, however, the

vehicle is characterized by alightness of draft and considerable stability.

Other objects and advantages of the invention will be apparent from the following claims,v

specication and drawings in which:

Fig, l is a perspective view of anembodiment of the invention; v .f

Fig. 2 is a plan view thereof;

Fig. 3 is an end elevation of the embodiment i ber I I two spaced members 25 are substitutedancl of the invention shown in Figs. 1 and 2;

Figs. 4 and 5 are vertical sectional views taken on the lines 4--4 and 5-5 respectively of Fig. 2;

Fig. 6 is a plan view of a modied form of the invention; and Fig. 7 is a vertical sectional view taken on the line 1 1, Fig. 6.

Referring first to the embodiment of thel invention shown in Figs. l to 5 inclusive the vehicle may be considered as formed of a frame and cover slats or staves, all preferably of wood. The

frame primarily'is composed Aof three cross members III, II and I2, lying in spaced parallel planes and each preferably shaped as the arc of a circle. Preferably also the .two opposite end members I0 and VI2 arel arcs of circles of equal diameters and are of equal length. The intermediate frame I I preferably is the arc yof a circle of larger diameter than the arcs of the other two transversemembers. Longitudinal members or rails I4 and I5 preferably are parallel and lie in parallel planes at right angles to the planes of the transverse members I0, II and I2. Each of the rails I4 rand I5 may be secured to each of the transverse members, as by bolts I6, preferably with the under face of each of the rails secured to the'upper face of the mesial transverse member II: and with their upper faces secured to the lower faces of each of the end transverse members I and I2. From a consideration of the above description and ofthe drawings it will be obvious Y,

that a trussed frame is presented which will support a covering that is convex both laterally and longitudinally of the structure.

The frame preferably is covered by or carries a multiplicity of slats, 20, of the barrel stave type, i. e., with their longitudinal axes arranged in parallelism but being slightly wider mesially than at their distal portions. Each of the staves ,20 are connected to each of the transverse members Ill, I I'and I2 as by screws 2I shown in dotted lines. In positioning the slats- 20 they preferably are placed in close juxtaposition with their inner facesabutting the outer faces of each of the transverse members but with the longitudinal edges of the two outer slats spaced from the rails I5. Thus a smooth bearing surface is obtained and at the same time room in left for the handsof thel operator to grasp the rails at any desired position.

In the embodiment of the invention shown in Figs.l 6 and '7 all elements are similar to those so far described and are similarly designated except that in place of the single mesial transverse memthe proportions 'of the vehicle lengthened long-i-v tudinally so that it may carry two passengers of normal size instead of one as is contemplated of `the structure first described. When this con-v struction is used the two central transverse members may be of equal convexty and the slats 20 partially flattened out therebetween as at 26.

Either of the lembodiments of the invention.

above described preferably should be sufficiently light in weight to be readily carried by hand but also the crossfmembers Ill and I2 are sufficiently sturdy so that a rope may be connected thereto to drag the vehicle over the snow if it is desired l `to put a load on it.

and lack of control when the vehicle is ridden down hill.' Thus a vehicle is provided in which skill and luck both enter into its successful operation. On the other hand for practical use,'when above described embodiment of the invention 2. A snow vehicle comprising a frame including in substantial parallelism a multiplicity of transverse members; two spaced marginal longitudinal members, said'longitudinal members being connectedat their ends with their upper surfaces abutting the end transverse members and connected intermediate their ends with their under surfaces abutting the intermediate transverse members; and a multiplicity of surfacing members connected to the under sides of said trans- 10 verse members.
