Application October 1, 1934, Serial No. 746,300 6 Claims. (Cl. 208-173) My invention relates to combination roller and ice-skating, the foot and heel rests being omitted ice skates and the principal object of my in for clari?cation of the drawing. vention is to combine in one article the usual Fig. 10 shows a rear view of Fig. 9 and illus roller skate and the usual ice skate, thus elimi trates how the two rear wheels may be removed 5 nating an extra pair of skates and permitting and one wheel placed in the center. a double use to be made of one pair of skates, Fig. 11 is a vertical sectional View of a part also with less expense. of Fig. 9 taken on the line l|—-l I.
