My invention relates to improvements in ice skates embracing two matched sections secured together, and one of the objects of my invention is to provide a particular construction whereby the cup sections are rigidly supported by the side walls of the tube sections. Another object of my invention is to individually assemble the heel-cup sections with the heel plate so that the flanges of these cup sections will be associated with the said heel plate on the upper side thereof, and in the following; specification, I shall set forth in a detailed manner the advantages flowing from my invention, and what I claim as new will be set forth in the claims forming part of this specification.

Fig. 1 is an exterior side elevation of one of the sect-ions forming part of a skate body or frame embraced within my invention, and showing the preferred form of construction. Fig. 2 is an elevation of the rear end of the section illustrated in Fig. 1. Fig. 3 is a vertical section on the line 33, Fig. 1. Fig. 4 is a side elevation of a complete tubular skate embodyin my preferred form of construction. Fig. 5 is a horizontal section on the line 55, Fig. 4, also showing in plan portion of the tubular member of the skate body or frame which carries the blade. Fig. 6 is a vertical cross section on the line 66, Fig. 4. Fig. 7 is a side elevation of one of the cup sections formed separately from the blade holder or tube, Fig. 8 is a vertical section on the line 8-8, Fig. 7, showing in addition, in assembly therewith, the two-part blade holder or tube and the blade supported thereby, in section, and Fig. 9 is a plan view of the heel plate in assembled relation with the heel cup.

In the drawing, like characters of reference refer to the same parts.

The prior art discloses ice skates made in two matched sections, but certain of the sections in the said art discloses the cup sections as joined to the tube sections at the upper or top edges thereof, thereby positioning these cup sections substantially wholly above the said tube sections with the result that the said cup sections have no deep anchorage with the tube sections in a line extending centrally longitudinally through said cup sections and transversely across said tube sections. In other words, the lower portions of the cup sections are not formed from portions of the side walls of the semi-tubular sections. Furthermore the prior art discloses the heel-cup sections as attached by means of'top flanges to the underside of the heelplate; a construction which is very weak.

in manufacturing' my skate body or frame, I prefer to make the two longitudinal sections or halves substantially simultaneously so as to reduce to a minimum the operations involved. In order to do this, I make a core of the desired shape and size, and make two dies one to produce the right-hand side of the skate body or frame, and the other to produce the left-hand side of the skate body or frame. These dies and core are of course properly support-ed, and two sheets of metal 7 of the desired gauge are used, one being placed below the core over the under die, and the other being placed above the core and below the upper die. When the operation is completed, the two halves or sections of the g skate body or frame are properly formed, and then the said members are subjected to the ordinary trimming operation by means of other dies.

Each frame section embraces a tube section 2; a forward cup section 3, and a rear cup section 4, as well as a flange 5. The flange 5 of each frame section from the rear end 6 of each tube section to a point above and behind the forward end of the said tube 5 section isolfset laterally in respect of the vertical plane indicated by the line 7 in Fig. 2, where the opposing surfaces of the securing flanges of the matched skate body or frame sections are secured together, thus forming shoulders 8. One only of these shoulders is illustrated in Fig 2.

When the frame sections are formed, and after they have been properly trimmed, certain suitable flanges are left, and it is by means of these flanges that the frame sections are firmly secured together, preferably, by brazing or spot welding. To the rear of the cup section l at the top of the tube sec- I tion 2 is left flange 9, and projecting beyond the rear portion of said cup section is a flange 10. These flanges merge together to form a web 11. A flange 12 at the top of the tube section 2, is located between the cups 8 and A, and this flange is connected by webs 13 and 14 to flanges 15 and 16 which project respectively forward of the cup section 4 and to the rear of the cup section 3. The flange 17 at the top of the tube section 2 extends from the forward shoulder 8 to the web 18, and from this web extends the flange 19 located at the forward side of the cup section 3.

After each frame section has been formed, the same are placed together in a suitable die, and from the top of each cup section 3 is simultaneously formed an outward substantially semi-circular flange 20. 23 is a one-piece heel-plate preferably, though not essentially, provided with a flange 2 1A surrounding an opening therein. In order to locate the heel-plate 23 around the upper portion of the rear heel cup the top of each cup section 4 must be passed individually through the opening 2% formed in said heelplate. The heel-plate is allowed to slide down this heel cup, and then the substantially semi-circular flanges 21 are formed from the cup sections 4:; afterwards these parts are assembled and are suitably held in place, and therefore it will be understood upon reference to Fig 1 that the flanges 21 lie upon portion of the upper surface of the heel plate 23, i

and as they overhang the sides of the opening 26%, a very strong construction is provided whereby it is impossible to separate the heel cup from the heel plate.

By any suitable means, the formed frame sections are placed together, and while so held, these sections are brazed or otherwise secured together through the medium of the flanges and webs numbered from 9 to 19. Then the heel plate 23 and the flanges 21 are secured together.

By offsetting the flange sections 5, space is provided between these flange sections to receive the blade 22, which blade is of course suitably secured in place.

As shown clearly in Fig. 2, the blade 22 is located so that a vertical plane represented by the line 7 will pass substantially through the vertical centre of said blade.

After or before the blade is secured in place, the sole plate is positioned and secured in place. The flange 20 of each forward cup section is brazed or otherwise secured to the underside of the sole plate 25, and the toe portion of said sole plate is secured by the angle braces 26 to the extension 27 of the blade 22.

lVhen the flanges 20 and 21 are formed, the upper portions of the flanges 10, 15, 16, and 19, for the width of said flanges 20 and 21, are pressed out or crushed so as to lie in close contact with their associated plates.

In the drawing, the flanges 9, 10, 15, 12, 16,

19 and 17 have been somewhat exaggerated for the purposes of clearness of illustration, but in practice these flanges will be made so as to extend as little as possible beyond the surfaces of the members they are formed from.

Obviously the flanges from 9 to 17, inclusive, of each frame section are in alignment since they must be brought into contact when the matched sections of the skate body or frame are brazed or welded.

As the drawing clearly shows, the cups are substantially conical in shape. It is possible to make the blade holder or tube of two separate sections, without integrally forming therewith the cup sections. It will be understood by one skilled in the art that these blade-holder sections will be made substantially as illustrated in Figs. 6 and 8, having integrally formed ther with the flanges 12 and 5, the flanges 5 being spaced apart after the flanges 12 have been secured together so as to leave the necessary space to receive the blade 22.

I It must be also understood that I may make the cup sections separate from the blade holder sections. When I follow this method of manufacture, the cup sections must be provided with each a flange 29, and these flanges are formed to conform to the exterior shape of the assembled blade-holder sections 2, as shown in Fig. 8. 1V hen the cup sections are formed separately, they of course each will be provided with the flanges 16 and 19, for example, and these cup sections will be brazed or welded together through the medium of the said last-mentioned flanges, and when so assembled, the flange 29 of each cup sect-ion will be spaced apart from its fellow so that the assembled cup sections may be position ed on the blade holder or tube by passing eacl over one end thereof as is now commonly done. When positioned, the assembled cup sections will of course be brazed or welded to the blade holder through the medium of the flanges 29.

It will be clearly seen from the drawing that the cup sections 3 and 1 measured on a line extending centrally longitudinally thereof are given a deep anchorage in the tube sections 2, and therefore I make use of portions of the walls of these tube sections, in combination with the webs 11, 13, 14- and 18 to firmly unite the said cup sections with their associated tube sections: this is a very marked and important advance over the prior art.

Any departure or change in the construction herein set forth and disclosed in the drawing forming part of this specification, that does not depart from the spirit of my invention, must be considered as falling within the terms of my claims.
