SKATE-FASTENlNC PEOl'l-ICATIQN forming part of Letters Patent No. 334,975, dated `anuary 26, 41886. Application filed December 12, 1885A Serial No. 185,530. (No model.)

To @ZZ whom it may concern:

Beit known that I, ULRIK OLsEN, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Skate-Fastenings, of which the following is a specification.

The object of my invention is to provide a cheap, simple, efficient, and convenient skatefastening, which may be adjusted to the various sizes of boot heels and soles, and secured thereto in a Very expeditious and permanent manner; and it consists in the construction, combination, and arrangement of the several parts of the fastening as hereinafter more fully described, and specifically set forth in the claim.

Figure 1 represents a side elevation of a skate-fastening constructed according to my invention. Fig. 2 represents a sectional plan showing the under side of the plate and fastening connected therewith. Fig. 3 represents a vertical cross-section at the heel portion of the same. Fig. 4 represents a vertical central longitudinal section of the heel portion of the same.

A represents the foot-plate of the skate, to the heel end of which is permanently secured the vertical projecting spur-points B, adapted to slightly enter the rear face portion of the heel of a boot when the skate-is fastened to the same at a point or points a short distance from the center of the boot-heel, as heretofore. The rear end portion of the foot-plate A has secured to the under side thereof the curved downward-projecting support-plates C, their lower end portions being secured to opposite sides of the skate-runner D by means of rivets, as shown. These plates C form a hollow passage, within which the rear downward-projecting end I of the horizont-al longitudinal sliding clamp-bar E may be moved back and forth by means of the clamp-screw G, the screw-threaded portion of which iits within a screw threaded opening or hole formed through the said projecting right-angle portion l of the said sliding clamp-bar E, and at the rear end portion of the said screw-threaded portion is formed a groove, F, within which is iitted the meeting edges of the rear vertical end plates, H, one at each side of the said clamp screw G, which is adapted to turn the boot, as described. The upward ends of v these guide-plates H are secured to the footplate A by riveting orany other suitable manner, and are fitted against the rear end faces ofthe said curved plates C, as shown. The said sliding clamp-bar E is provided with a longitudinal slot, K, within which the short clampbolt L is fitted, so as to permit the said clampbar E to slide thereon. The upper end of the said clamp-bolt L is provided With the adjustable sliding dog M, which is curved rearward at its upper end, and sharpened or somewhat pointed, so as to pierce or slightly enter the inward face of the boot-heel as the skate is clamped thereon. Now, in order that the sliding dog M may be adjusted upon the said sliding clamp bar E so as to iit differentsized boot-heels, the said clamp-bolt L is provided with shoulders and a screw-threaded.

nut, so that its position on the said clampbar E may be adjusted and moved back or forward on the clamp-bar by sliding the said bolt L in the slot K of the bar E, and securing it in such position by means of the said fastening-nut. It will be seen that the said foot-plate A is provided with a longitudinal slot corresponding with the slot K, formed in the sliding clamp-bar E, to Vthe forward end of which sliding clamp-bar is pivoted the rear ends of the opposite side-curved oblique sliding clamp-bars N, the forward ends Pt of which are bent upward, and project a short distance above the top of the foot-plate A, and then are bent inward, so as to grasp the opposite edges of the boot-sole toward the toe portion, as heretofore. The said curved sliding clampbars N are provided with short slots P, near their forward ends, and are retained in position upon the foot-plate A by short screws or bolts S, inserted through the slots P and into the said plate A, as shown in Fig'. 2.. The curved oblique sliding clamp-bars hl are each pivoted to the forward end of the straight sliding bar E by a short screw-bolt, T, which ICO' passes through holes formed through the ends' of the same, and in ashort slot formed through the said foot-plate A, whereby the skate being adjusted to the size of the boot and placed in position upon the same, and the clampingl` screw G turned in the proper direction, the clamp-dog M takes hold of the face of the front ofthe heel, and the spur-points B are setinto the rear face of the same, and oblique clamp-bars N are drawn inwardly at their forward ends, and thus their hooked projecting ends It grasp .the edge of the sole of the boot toward the toe portion, and thus secure the skate irmly in position thereon. It will be seen and understood that the said actuating clamp-screw G, provided at the heel of the skate, is in position to be turned by means of the lingers of the skater in a very convenient and expeditious manner so as to actuatc all three of the holding-dogs or clamping devices at one and the same time, and that by passing any suitable device'through the opening in the out- Wardend of t-he clamp-screw G great pressure can be easily brought to bear upon the sole and 4heel of the boot, so as to cause the clamps to hold the skate on the same with great security and rmness. 4

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

The skate-fastening consisting of the cornbination of the curved plates C, vertical plates H, clamp-screw G, provided with a groove, F, and sliding bar E,having the slot K, and provided with the bolt L and adjustable sliding dogM, and having pivoted to the forward end thereof the curved oblique sliding clampbars N, having slots P, provided with bolts S, and having hook ends R, all being constructed and arranged to operate with the footplate A,provided with a longitudinal slot, and

having spur-points B, substantially as shown and described.

ULRIK OLSEN.
