J. SAYER ICE SKATE BLADE Oct. 13, 1931.

Patented Oct. 13, 1931 UNITED STATES JOHN SAYER, OF FLAGSTAFF, ARIZONA ICE SKATE BLADE Application filed May 22,1930. Serial No. 454,776.

This invention relates to an improved ice skate blade.

One object of the invention is to provide a device of this character which will tend to 5 sharpen itself while in use, thus obviating the necessity of employing sharpening tools.

Another object of the invention is to provide a skate blade which will be formed to cut into the ice in such a manner that a ridge of ice will be defined to coact with the blade for preventing side slipping of said blade.

A further object of the invention is to provide a skate blade having a soft core and a slot in said core which will permit more rapid self sharpening of such blade.

Other and incidental objects of the invention not specifically mentioned in, the foregoing will appear during the course of the following description.

In the drawings:

Figure 1 is a side elevation of a skate employing the improved blade, said blade being partly broken away and shown in section,

Figure 2 is an enlarged vertical sectional view on the line 22 of Figure 1, and

Figure 3 is an enlarged fragmentary sectional view, showing the blade with the concave lower edge partially worn away.

Referring now more particularly to the drawings, 1 have shown the present improvement in connection with an ice skate which includes a conventional foot plate 1, clamp 2 and strap 3.

Formed integrally with or otherwise secured to the foot plate 1 is a preferably steel blade l which comprises relatively hard outer walls 5 and a relatively soft core 6. The blade is also provided with a turned up toe 7 and a rearwardly extending heel 8. As seen more clearly in Figure 2 of the drawings, the

blade is gradually thickened, or flared, toward its lower edge, and said lower edge is ground to form a concave face 9 which extends throughout the length of the blade. 45 The concave lower face 9 defines sharp edges 10 throughout the length of the blade for the l relatively hard walls 5. It is pointed out that the outer walls may be hardened by the case hardening process, or in any other approved manner, and after such hardening has been effected, all traces of hardness will be ground off, or otherwise removed, from the face 9.

Formed in the core 6 of the blade 4 medially of the relatively hard outer walls is a longitudinally extending rectangular slot 11. This slot 11 extends throughout the length A of the blade and is substantially equal in depth to the thickness of the core 6, at its lower edge. The mouth of the slot is provided with right angular corners 12.

It will be observed that when the blade is L in use, the edges will out into the ice and define a ridge which will coact with the surface of said concave lower edge to prevent side slipping of the blade. It will be further observed that the continuous engagement of the concave lower face 9 with the ice while the skate is in use will, due to the relative softness of the core 6, tend to cause rapid wear upon said core so that the concave face will be made increasingly deeper by such con tinuous wear. As shown in Figure 3, this repeated wear will tend to keep the corners 1O sharp, thus obviating the necessity of employing sharpening tools for this purpose.

The corners 12 defining the mouth of the slot 11 will be ground down in a relatively short time due to the comparative softness of the metal. Thus it may be seen that the slot tends to aid in constantly deepening the concave lower edge.

It should be understood that although I have described the blade as being formed integrally with the foot plate 1 of the skate, said blade may be separable from said plate if preferred without departing from the scope of my invention.

Having thus described the invention, I claim:

1. An ice skate blade having a concave lower face and provided with relatively hard outer walls and a relatively soft quick wearing core ex osed at said face, said core being provided with amedial slot opening onto said 5 concave lower face.

2. An ice skate blade having a concave lower face and provided with relatively hard outer walls and a relatively soft quick wearing core havin a; medially disposed slot openin onto said ace, said face cooperatin with said hard walls to form sharp cutting edges at the lower outer corners of the blade.

In testimony whereof I afiix my signature. 1 JOHN 'SAYEB. [1 s.]
