SKATE.

SPECIFICATION forming part of Letters Patent No. 439,161, dated October 28, 1890. Application filed December 3, 1889. Serial N0. 332,457. (No model.) Patented in Sweden .Iannary 301889, No. 1,936.

To @ZZ whom, it may concern:

Be it known that I, RICHARD EMIL KRAUsE, a subject of the King of Sweden, residing at Gteborg, Sodra Haunigatan 33, in the Kingdom of Sweden, have invented Improvements in Skates, (for which I have obtained Letters Patentin Sweden January 30,1889, No. 1,936,) of which the following is a specification.

lWIy invention relates to the construction of skates.

In skating it is important that. the bottom edge of the runner of the skate which comes in contact with the ice shall have a proper curve, and the object of my invention is to so construct skates that a skater can easily regulate such curve. This regulation of the curve of the bottom edge of a skate-runner can be accomplished in various ways.

According to my invention I accomplish this result by adj listing-screws operatin g upon the runner horizontally and longitudinally in directions parallel with the runner and through suitable connecting devices constitutin g a part of the frame of the skate, whereby the whole structure is rendered very'strong and a certain flexibility or capacity for yielding permitted to the runner.

In the accompanying drawings, Figures 1 and 2 are side elevations of skates, showing, by way of example, two different means of carrying out my invention, which I will irst describe by reference to Fig. 1.

B indicates the runner proper, which is of sufficiently small dimensions vertically to be bent or curved by pressure to the desired degree.

D and E indicate the posts, which support the sole-plate F and heel-plate F upon the ends of the runner.

G is the longitudinal screw, and G a correspondingly internally-threaded part, by the relative longitudinal movement of which the runner is curved to the desired degree.

It is obvious that the invention can be moditied in various ways. For example, instead of using a screw or screws for adjusting the curve of the runner, an eccentric or eccentrics, wedges, or their equivalents can be employed. In Eig. l the screw is non-rotary, being connected by a rod g with the post D,

while the internally-threaded part G is r0- tary, constituting in effect a turn-buckle. In

Eig. 2 the screw is rotary and the internallythreaded part non-rotary, the latter forming a part of a longitudinal bar g', which is connected with the post D. In either construction I prefer to employ an additional oppositely-threaded screw G2. by which the rapidity of adjustment is enhanced. It will now be readily understood that by turning the rotary part (G in Eig. l or G in Fig. 2) the ends ot the runner B will be vcaused to approach or recede from each other, as may be desired, and the required curve in the flexible blade thereof produced. In Eig. 2 an inclined plane bearing at I is provided betweenV the bar g and runner B, which gives support to the rear part of plate E and aids in curving the runner. On one of the parts of the runner one or more pins can be applied, which pass into holes in the other part or embrace the same on the sides. Both parts are thereby rendered more secure from lateral movement in relation to each other. Instead of j ointing the two parts of the runner at their ends and fitting the adjusting screw or screws or the like between the said joints, l can place the joint at about the middle of the said parts and apply the adj listing-screws or the like near their ends. The screws or the like can then be made to operate by pressure or by tension, according to the way in which the runner is to be curved.

Having now particularly described and ascertained the nature of the said invention, and in what manner the same is to be performed, I declare that what I claim is Y In a skate, the combination, with the footplates and the flexible runner B, of a longitudinal adjusting-screw, and connections between said screw and the ends of said runner,

whereby the latter may be curved, substantially as set forth.

vIn witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
