3 Claims.

This invention relates broadly to ice skates, but more particularly to the method of manufacturing a one piece metal skate.

One object of this invention is to produce an improved method of manufacturing a one piecemetal skate preferably made of steel alloy best suitable to resist wear to which ice skates are subjected, and eliminating the use of riveted or Welded joints heretofore incorporated in commercial ice skates, which joints are apt to become loose due to the corrosion and stresses to which they are subjected.

Another object of this invention is to produce a i one piece ice skate made of forged or pressed steel alloy and shaped to form an attractive and light unit which is strong, durable and comparatively inexpensive to manufacture.

Other objects of this invention will be apparent from the following detailed description wherein similar characters of reference designate corresponding parts and wherein:

Fig. 1 is a top plane View of a partly finished skate manufactured in accordance with the invention.

Fig. 2 is a side elevational view of the skate shown in Fig. 1. i

Fig. 3 is a cross sectional view taken in a plane indicated by line 33 in Fig. 2, showing a portion of the roughing dies used in the manufacture of the skate.

Fig. 4 is a view similar to Fig. 3 but taken in a plane indicated by line 4-4 in Fig. 2.

Fig. 5 is a top plane view of a finished skate manufactured in accordance with the invention.

Fig. 6 is a side elevational view of the skate shown in Fig. 5.

Fig. 7 is a cross sectional view taken in a plane indicated by line 1-1 in Fig. 6, showing a portion of the finishing dies used in the manufacture of the skate.

Fig. 8 is a View similar to Fig. 6 but taken in a plane indicated by line 8-8 in Fig. 6.

My improved method of manufacturing one piece skate may be divided in two distinct stages hereinafter referred to as the roughing and finishing operation. The first stage or roughing operation consists in taking a piece of metal and shaping it substantially as shown in Figs. 1 to 4 inclusive. This operation is preferably accomplished by either forging or pressing between two dies l0 and H a piece of steel alloy so as to produce a rough blank shaped to form a runner 12 having its front end turned slightly upward as at I3 and terminated by a standard l4 extending upwardly therefrom but leaning toward the runner 12 to form therebetween an acute angle. At its free upper end, this front standard is enlarged to form a partly spherical end I5, the purpose of which will be explained later.

Intermediate its ends,-but disposed closer to the front than to the rear end thereof, the runner I2 is provided with a second or middle standard 5 also terminated with an enlargement or sphere H. The runner l2 and front standard M are preferably made of a rectangular cross section of substantially equal thickness, with that of the standard somewhat shorter than the cross section of the runner, while the middle standard [6 under the enlargement I1 is made materially thicker than the runner to form a substantially ovalshaped cross section. From under the-enlargement H, the side walls of the standard [6 are, tapered toward the runner to merge therewith and form adjacent thereto a rectangular cross section somewhat longer than that of the runner.

The rear end of the runner is also slightly turned upwardly as at l8, while the runner adjacent this one end is provided with a third or rear standard [9 extending upwardly therefrom and leaning slightly toward the rear end of the runner. This third standard is somewhat longer than the other standards, and has its free upper end also formed with an enlargement 20. The cross sectional shape of the standard I9 is substantially the same as that of the middle standard [6, except that the area of. its cross section under the enlargement 20 and at its base is somewhat smaller than that of the standard I6.

After the roughing operation, the blank shaped as shown in Figs. 1 and 2,15 removed from the dies 10 and l I and placed between two dies 2| and 22 which are clamped together against relative movement by any suitable means. These clamping dies are shaped to fit over the runner and the standards of the skate, while the enlargements I5, I! and 20 protrude from the dies 2| and 22, as shown in dotted lines in Figs. '7 and 8. Subsequently, these enlargements are either forged or pressed by a movable die 23 into the shape shown in Figs. 5 and 6 to form plate like foot rests 24, 25 and 26 of a shape corresponding to that of the dies 2 l, 22 and 23 adjacent each enlargement.

After the skate is finally shaped as shown in Figs. 5 and 6, it is removed from the dies 2! and 22 and the

plates

24, 25 and 26 are thereafter either drilled or punched to provide the holes 21 adapted to receive screws or the like for securing theskate to the shoe.

I claim:

1. The method of making a one piece ice skate which comprises forging a metal blank between dies of suitable shape to form a runner having three standards extending upwardly therefrom each terminated by a substantially spherical enlargement, and subsequently upsetting said enlargements to form at the end of each standard a plate-like foot rest.

2. The method of making a one piece ice skate which comprises forging a metal blank between dies of suitable shape to form a runner having front, middle and rear standards extending upwardly therefrom with the front standard leaning rearwardly from the front end of the runner, each standard being terminated by a substantially spherical enlargement, and subsequently upsetting said enlargements to form at the free end of each standard a plate-like foot rest.

3. The method of making a one piece ice skate which comprises forging a metal blank between dies of suitable shape to form a runner having front, middle and rear standards extending upwardly therefrom with the rear standard leaning slightly rearwardly relative to the front end of the runner, each standard being terminated by a substantially spherical enlargement, and subsequently upsetting said enlargements to form at the free end of each standard a plate-like foot rest.
