1,097,875, Patented May 26, 1914 Attest: ventor: 7 T by QM GEORGE L PIERCE, OF BROOKLYN, NEW YORK.


Specification of Letters Patent.

Patented May 26, 1914.

Application filed April 1, 1912. Serial No. 687,554.

To all whom it may concern:

Be it known that I, GEORGE L. PIERCE, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Skates, of which the following is a specification.

My present invention'relates to skates and permits the user to adjust his shoe to the skate to have any desirable height and inclination at the heel and toe respectively.

The improvement is especially valuable in skates for fancy skating and in any case where it is important that the skater be accurately poised in a special position on the skates.

The drawings show only one of the specific embodiments which my invention is adapted to take. In them, Figure 1 is a side elevation of a skate within my invention; and Fig. 2 is a vertical section on the line 22 in Fig. 1.

I will now describe the specific devices .of the drawings.

1 is a runner of a fancy skate; 2 and 3 are the heel and toe plates or supports respectively, having holes for the screws by which they are secured to the shoe.

t is a transversely perforated lug on theunder side of each of the plates 2 and 3, received between the similarly perforated sides of the bifurcated head 5 on the screwthreaded bolt 6.

11 is a pivot pin in the form of a bolt passed through said perforations to permit the plates 2 and 3 to tilt forwardly and rearwardly.

7 is an internally threaded socket fitted by the bolt 6 and constituting the head of a member having a bifurcated shank 8 which straddles the upper edge of the runner and is rigidly secured thereto by rivets 9.

By screwing the bolt 6 to a greater or less distance into the socket 7, it is apparent that the exact desired poise and tilt of the skater on the skates can be secured.

1010 are look nuts on the bolt 6 which prevent variation in the desired up and down positions into which the toe and heel plates have been adjusted. Finally, the fact that these plates can be tilted forwardly and rearwardly makes it possible for them to conform to the forward and rearward tilt of the sole and heel of the shoe whatever that may be.

The reason that the pivot pins 11 are preferably bolts is that a wrench can be applied to the nuts of the pivot bolts 11 so as to grip the lugs 4 tightly between the sides of the bifurcated heads 5 after the desired adjustments of height and inclination of the toe and heel relative to the skate have been made.

It will be seen that the improvement is further advantageous in making it possible to lit the skate properly to any shoe irrespecfive of the relative thickness of its sole and ieel.

What I claim is l. A skate, including a runner, a shoe-supporting plate, and an extensible connection between the runner and plate, said plate having a pivotal connection with the upper end of said extensible connection including a substantially vertically supported screw.

2. A skate, including a runner member, a shoe supporting plate member, a socket element carried by one member, and a stem element vertically carried by the other member and adjustably threaded in the socket element, providing an extensible threaded connection between the members, one element being pivoted to its member.

3. A skate, lncluding a runner, a bifurcated socket element secured thereto, a shoe supporting plate member, a threaded shank pivoted thereto and having an aohustable threaded engagement in the socket element whereby said shank may be rotated to vertically advance within said socket element, and a jam nut threaded on the shank.

In testimony whereof Iaflix my signature in presence of two witnesses.
