1 Claim.

This invention relates to skates of the tubular t e.

it aims to improve both the construction and methods of manufacture of skates of this char- 5 acter with a View to reducing the expense of making such articles While providing an exceptionally strong and sturdy construction. It is also an object of the invention to devise a light weight skate which will be composed chiefly of sheet metal parts or sections.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claim.

In the drawings,

Figures 1 to 5, inclusive, are perspective views illustrating, respectively, the dilferent parts, of a skate embodying this invention;

Fig. 6 is a side View of the complete skate;

Fig. 7 is a plan view on a larger scale of the skate shown in Fig. 6;

Fig. 8 is a front elevation of the skate shown in Figs. 6 and 7 and Figs. 9, 10 and 11 are sectional views approximately on the lines 9-9, 1010 and 11-11, respectively, Fig. 6.

Referring first to Figs. 1 to 5, inclusive, it will be seen that the various skate parts there shown include a heel plate 2, toe plate 3, two frame sections 4 and 5, respectively, and a runner 6. All of these parts except the runner may be made from sheet metal by means of suitable punches and dies.

The two parts 4 and 5 are substantially symmetrical and are adapted, when properly secured together, to form what may be termed the frame of the skate. These sections form the two halves of a skate frame when divided along its longitudinal median plane, but are so designed as to facilitate their manufacture from sheet steel or certain of the more recently developed alloys which are light in weight but have a high degree of mechanical strength. In assembling the parts the two sections 4 and 5 are brought together with their fiat faces abutting and corresponding elements registering with each other, and they are welded together in this relationship. This operation may be performed either by spot welding the parts at intervals or by making substantially continuous welds to unite the flanges of the sections to each other. The lower margins a and b of the sections 4 and 5 are offset in opposite directions sufiiciently to provide a groove in the lower edge of the frame to receive the runner 6,

(Cl. 208167) I as will be evident from an inspection of Figs. 3, 4, 6 and 10. When the two side sections have been welded together, the runner then is placed in this groove and is welded, either by spot welding or by substantially continuous welds, to the margins a and b. While the runner should be made of a high grade steel and may, if desired, be hardened, it can be assembled with the other parts in this manner without injury to the portion of the runner which will engage the ice.

The foot plate, which, in this case, is made in two pieces, is next secured to the upper end of the frame. It should be observed that when the sections 4 and 5 have been welded together the frame then includes a relatively large hollow rear post 7 having a fiat flanged top, a similar intermediate hollow post 8 and a smaller tubular toe post 9. It also includes a tubular section 10 lying immediately above and parallel to the runner 6. The heel plate 2 is welded to the upper end of the post 7, while the toe plate 3 is welded to the upper flanged ends of the posts 8 and 9. These plates have suitable holes punched through them to receive the screws and rivets by means of which the skate is secured to the sole of a shoe.

Due to the peculiar construction of the frame sections and the manner in which they are secured together, the frame may be made very light in weight while still having ample strength.

The invention thus provides a skate composed entirely of sheet metal parts except for the runner 6, the manufacturing operations being such that the expense for both materials and labor is relatively small. In addition the skate has the attractive appearance peculiar to skates of the tubular type while being far more economical to manufacture than the common tubular skates.

Having thus described my invention, what I desire to claim as new is:

A skate of the tubular type comprising a skate frame including two similar sections, welded together, and both extending longitudinally of the skate, said frame having a groove in its lower edge, a runner secured in said groove and welded to said frame, said frame having a tubular section parallel to and immediately above said groove and including two hollow posts extending upwardly from said tubular section, the frame also having a hollow post at its front end, a heel plate welded on the upper end of one of said posts, and a toe plate welded on the upper ends of the other two posts, said welded plates being adapted to functionally effect an additional securing means between said frame sections.
