Description

ICE SKATE Filed eb. 15, 1944 Patented Aug. 8, 1944 ICE SKATE William Sim, Ralston, and Katherine Mary Shields, Prestwick, Scotland Application February 15, 1944, Serial No. 522,424 In Great Britain January 8, 1944 1 Claim.
This invention relates to improvements in ice skates used for exhibition skating.
An ice skate according to the invention has a blade or runner formed with a depending spike at its forward extremity, and, at a short distance behind the spike, with an inwardly directed tooth having a plane under face presenting in conjunction with the vertical face of the tooth near to the spike an edge transverse to the length of the blade.
In the accompanying drawing which illustrates the invention Fig. 1 is a perspective view of the improved skate as fitted to a boot for the left foot.
Fig. 2 is a fragmentary side elevation and Fig. 3 a fragmentary inverted plan view, of the front portion of the skate.
Fig. 4 is a horizontal section on the line 4--4 of Fig. 1.
As shown, the blade I of the skate is formed at the forward extremity with a vertically depending spike 2 associated with which is a lug 3 adapted to prevent excessive penetration of the spike 2 into the ice.
Close behind the spike 2 the blade is formed with a tooth 4 directed inwardly, that is, towards the right. The tooth 4 has a plane under face 6 intersected by the vertical face of the tooth nearer to the spike 2 to form a sharp edge transverse to the length of the blade.
At its free end the tooth is chamfered, so that, if it enters a hole in the ice, it will clear itself.
The outer end of the tooth 4 is chamfered dihedrally so as to form at the outer end of the face 6 a sharp corner I, the outer end of the tooth thus somewhat resembling the bow end of a ship.
The skate is particularly adapted for the performance of spinning on the ice.
At the commencement of the spin, the performer moves in a circle around the forward portion of the blade. As her heel rises, the skate travels in a gradually diminishing circle, the sole of the tooth and the ground edges of the forward portion of the blade contacting with the ice. As the performer rises on her toes, the spike 2 digs into the ice and the performer spins around a centre constituted by the spike, the sole 6 of the tooth 4 becoming free of the ice except for the edge 5.
In this position of minimum radius of spin the ice is not excessively ground into powder and thrown upwards and outwards.
As will be understood, the skate for the right boot is to the opposite hand to that for the left boot.
We claim:
An ice skate having a blade formed with a depending spike at its forward extremity, and, at a short distance behind the spike, with an inwardly directed tooth having a plane under face presenting in conjunction with the vertical face of the tooth near to the spike an edge transverse to the length of the blade.
