In the drawing: 30 Figure 1 is a view in side elevation of a ski runner constructed in accordance with an em substantially one end to the other are the. rein-4r forcing members 1 of light weight steel alloy or other comparatively light material. These mem bers 1 are L-shape in cross section with their foot ñanges a contacting the runner l and their leg flanges b upwardly disposed. As herein em Figure 2 is a sectional view substantially on the line 2_2 of Figure 1, looking in the direction 35 l bodied, the leg flanges b of adjacent members 1 of the arrows: abut and the sum of the lengths of the foot ñanges a equals the space between the flanges 4.

In the embodiment of the invention as illus trated in Figures 1 to 3 of the drawing, l denotes an elongated runner preferably of a light weight posed over the runner l and resting from above on the upper edges of the legs b of the members 1 and the upper edges of the flanges 4 is a cover sheet or plate 8. This sheet or plate 8 is of a ' l alloy or other equally light weight material and is preferably of slight thick ness. The side marginal portions of the sheet >or plate 8 overlap, as at 9, the outer face of the upper portions of over a snow terrain thereof is disposed upwardly on a short radius -to provide a heel 3 to facilitate backing up of the runner and more especially when the snow terrain is deep. the flanges 4 and are welded. 50 or otherwise secured. l The forward end portion of the sheet or plate 8, or that portion overlying the forwardly up wardly disposed portion 2 of the runner I. is provided at its transverse center with an up- t 55 standing blade I0, which provides means to facili 2,404,402 » _. the bottom face of the body being ilat, and a rib depending from said bottom face and extending from the start of the up-curve at the forward end rearwardly to the end of the up-curve at the tate travel of the runner should the same pene trate a ysnow drift or the like.
