7 Claims. (01. 2 so 11.17)

This invention relates to the manufacture of ice skates of the so-called tubular type.

Such skates have runners to which are attached longitudinal tubes on which are mounted the heel and toe plates. Usually discrete conical supports are interposed between the tube and the shoe plates, welded to the opposite sides of the tubes andto the underside of the plates. It has also been proposed to form the tube of two parts with one-half of the support integral with each half of the tube. It has also been proposed to butt weld the lower end of the sleeve of a shoe plate to the end of a sleeve formed integrally with the tube. Each of these methods of construction has objections, such as high cost of construction, Weakness, poor appearance or resulting corrosion, which I have sought to overcome by a special invention, the subject of this application.

I provide a tube whichis suitably secured to the runner and in the preferred form has upstanding collars. The toe and heel plates have supports drawn downwardly, with a neck or boss closed at the bottom, inserted into said collars and welded or brazed in place. As an. alternative, a neck portion may be formed as an imperforate boss drawn up from the tube so as to provide a transverse web inserted into the lower end of the conical support. The tip of the toe plate may be brazed or welded directly to the front end of the runner when used.

. '23 p The runner 8 is of any suitable shape and material and may have an extension post 9 at its front end. I

The tube 10 is formed in the usual manner from a single piece or blank of.sheet metal II and maybe provided with flanges I2 which are secured to the sides of the runner for instance by electric welding r brazing. The upper wall of the blank is pierced at l3 and providedwith shallow upwardly drawn oval or elliptical collars I4 and i5. It is not necessary that the shape be that of a mathematical ellipse but generally the collars are of elongated shape.

To form the collar, an elongated slot 13 is'iirst punched through the. blank ll from whichj the tube is to be formed. The length of this slotis a little less than the long axis of the ellipse or oval of the collar so that there is sufficientinetal at the sides and ends of the slot from which the walls of the collar may be drawn. The slot'is naturally narrower than the oval so that there is enough metal at the sides to draw up and form the extended sides of the collar. The collar may be formed while forming the tube and the upper edges of the 'collar are smoothed off by grinding or otherwise so. as to provide a surface into which the neck of the post" can be fitted and brazed or welded at the ends andat the extended sides of the collar)" The collar 'is preferably of oval or elliptical shape in plan and of a width approximately equal to the horizontal diameter of the tube and of considerably greater length.

The toe plate It has a supporting post I! which is formed as an integral part thereof by a drawing operation which forms a cup and leaves the bottom I8 closed. This post is of an oval or elliptical horizontal section gradually tapering downwardly and ending in a reduced neck [9 which fits snugly in the collar I4 of the tube where it is welded or brazed in place leaving no opening for water to leak into and stand in the tube and rust the runner or the tube.

The front end of the toe plate I 6 may be brazed or welded to the extension 9 of the runner when used. The toe plate is preferably slightly concave longitudinally as well as transversely so as to greatly strengthen it and adapt it to the shape and pressure of the shoe.

The heel plate 20 is similarly formed. and has a tapering, integrally drawn, supporting post 2| of oval or elliptical horizontal cross-section ending 'in a reduced neck 22 closed at the bottom 23 and fitted into the collar 15 of the tube and brazed or welded in place so as to produce a smooth finish,

The reduced neck of each supporting post telescopes in a collar on the tube so that there is a substantial area of contact for joining.

The closed lower ends of the posts I? and 2| reinforce the joints by providing transverse walls which assist in preventing lateral collapse of the posts and tube.

In makingzaa skate of course 'the's'bladep the tube with its collars, and the toe and heel plates with their cap-like posts are separately formed. According to the preferred order of assembly, the tube after being formed is attached to the blade. The necks of the posts of thectoeland heel plates are then inserted into the c'bllars Cf-Qthdtilbe and welded or brazed in place. of the toe plate is then welded or otherwise secured to the upper end ofithvextension of the blade when the blade has such an extension. This order of assembly: is the most satisfactory cone .from a ,jpracticalfshop standpoint, but it :Ishould; be ..understo.df that the broad"'invention is not limited except as called" for byfthegclaims. lE'iga l2lshcws .a modification ,in.,whi'ch the; tube lllflis provided withan upwardly -dravvn imperforateflbossl I9,,ofjhorizcntal1y; elongated shape.
