SKATE.

Application led October v30, 1926. Serial No. 145,215.

My invention is an improved skate, stiffened against longitudinal and transverse strains upon the runner by side braces applied to the runner and against vertical and transverse strains applied to the foot plates andtheir supporting posts by braces applied to the posts connecting the runner with the foot plates, the two sets of braces, for the ruimer and the foot plates and their posts being independent, My invention also includes a novel depending bracket for securing the toe plates to the upright posts from the blade as well as a novel reinforcing element to be applied to the sides of the posts and to cooperate with the depending bracket.

The invention is particularly applicable to skates in which a relatively thin blade or runner is employed.

In the drawings: v

Figure 1 isa longitudinal elevation of my improved skate;

Figures 2 and 3 are sections upon an enlarged scale, on lines 22 and 3-3, respectively, of Figure 1;

Figure e is a fragmentary plan view, on an enlarged scale, of one end of the blank from which the horizontal stiffening element is formed; n

Figure 5 is adetail sectional view online 5--5v of Figure l;

Figure is a plan view of Figure 1;

Figure 7 is a perspective view of one of the stiffening members, shown in Figures 2 and 3;

Figure 8 is a section on lineS--S of Fig ure 7, and i Figure 9 is a detail of Figure 2.

My invention is particularly applicable to skates in which the blade or runner is thin and, without extraneous support, would be too flexible for satisfactory results. The blade in my new skate is formed, as is cornmon, of a horizontal runner or carrying part A, perpendicular to which are four integral posts al, a2, a3, a4. To the upper or free ends of these posts are secured a dupleX'toeplate BB', each part of which is provided with depending brackets, b and 1 and a duplex heel plate DD each part of which is provided with depending brackets ol and 1.

The posts a2, a3, respectively beneath the ball of the foot and the front of the heel are subject to great transverse strains as well as most f 'the vertical pressure due to the have found that the 51 the skaten ordinary post, integral with the blade, such as `the front and rear posts, a1, at, is not adapted to endure the transverse strains of the medial position and preserve perfect alignment with respect to the foot plates andA the straightness of the blade A itself andV this is especially true when, as is desirable, the blade is thin and therefore fiexible.

To correct this difficulty I provide posts a2, a?, with side reinforcing elements 2, which' lie on either side of posts a2, a3, from theV plained, as shown at 2a (Figure 7) and are.

provided with an aperture 2b, surrounded upon the outer side of element 2 by a thimble, 2c.` The aperture 2b registers with an aperture 2b in the reinforce 2 `upon the other side of the post a2 or a3 and with an aperture in' the tliimble 2C surrounding this aperture 2l.

ylfhese apertures through the reinforces.

thimbles and posts a2 or a3 areto receive ar bolt or rivet 1b passing through the brackets 1 and locking all the parts together. Y

Thebrackets and al are such as have heretofore been in use in connecting the front end of a toe plate with the front post and the rear end of a heel plate with the rear post. The brackets 1 are novel in shape, being hollow concavo-conveX segments of a sphere, set back from the opposed edges of the duplex heel and toe-plates, and are so shaped in order to provide necessary space for the reinforced upper ends of Vthe runner posts, while covering with a sturdy and graceful bulbous casing the structure contained. In order to provide the necessary mechanical strength, for the bulbous bracket, each bracket 1 is provided with an inwardly proj ect-ing hollow cylindrical thiinble, 1a, the free end of which preferably projects to butt upon the free end of thimble 2c projecting from the outer face of element 2. It is nbL vioiis'that the cylindrical tliiinbles, 1t, 2% aiidelc'inents 2 and post a2 or as be 1con` iicted by a i passing brackets,

thimbles, reinforcing elementsand posts and securedwith firmness, the pressure being vsustained by thethimblee reinforcing elements 2 and the posts.

The reinforcingl Inernbers 2 being applied to posts a2, as, and'li-Xedv in place, by *spot Welding, riveting or other suitable method,

Y the longitudinal stilfeni'ng member E is ap"- plied bypassing apertures, e, in the blank E over the free ends of the posts and secur ing-the tyvo edges ofthe member E' tegether preferably by rivets ey passing through suitable apertures e? in the edges of member 'E inthe blade A (see Figures 1, 2 and e).

n The toe andv heelplatesare next `mounted Y uppn theirirespective posts, al, a? and. a3 and at and the brackets b, d, areirivete'd there-V to by rivets b ql passing .through'suitab'le apertures-in the brackets 'and the upper end ogf posts al, gi, and the brackets l are connected by, ineansof rivet lb passing through thmblee l?, 2C eed1 aperture 2b inthe rein;
