HENRY BEZER in LONDON. Innovations in ice skates.

Patented in the German Empire on June 16, 1881.

The present invention relates to the construction of ice skates that fit the cavity of the Fufses provide direct support.

The innovation is to fix the skate by means of a spring plate, whose Shape that corresponds to the cavity of the boot between heel and sole and which is attached to it connecting different heel heights yourself.

1, 2 and 3 of the accompanying drawings show a skate which, after a modification this invention is built. Fig. 1 is a plan view, Fig. 2 is a plan view, Fig. 3 is a view from underneath. Two further modifications are shown in FIGS. 4, 5, 6 and 7.

On the skate shown in Fig. 1 to 3 , a heel plate b and a plate c for the front part of the foot is attached to the running rail α. At the end of the plate b there are clips or projections d against which the back of the heel rests. In the front part of this plate is a slot e in which a slide f moves; the same grips with two arms f ¹ under the plate and sits at the end of a screw g that ■ goes in a nut h , which is movable lengthways. On both sides of the front plate c are cheeks i, which grasp the sole. These jaws are supported by plates k , which are located below c and slide with pins / in slots m of a piece η below. The piece η can be moved along the running rail α and sits at the end of a screw o which carries a nut / and lock nut q. Depending on whether η is moved forwards or backwards, the jaws i go together or apart.

In the middle of the skate lies the mentioned spring plate r, the shape of which is adapted to the hollow of the foot. At the rear end it has a slot or an opening r ^l , by means of which it engages over the screw g , and it rests against the front of the sliding nut h . At the front end, the plate is bent over and rests against the back of the nut p , whose screw ο also goes through a slot in r. Behind this nut, the plate r also has a slot s, which comprises a projection t on the running rail, which allows the plate a certain longitudinal movement.

Such a skate is attached as follows:

First the jaws i are adjusted according to the width of the sole by moving the piece it forward until they grip the sole; then screw p back until it rests against the leading end of r. The position of the cheeks i achieved in this way can be maintained as long as the same boot is used. After you have put your foot into the skate by pushing it forward (so that the sole is pressed between i ), the slide f, which has been set approximately after the heel, is moved backwards with the aid of screw g and a wrench . Here, h remains firmly in place. As soon

but the slide / is prevented from further backward movement, the further rotation of the screw g results in a forward movement of the nut h on the running rail, which thereby acts on the plate r; the latter is pressed forward in this way, first of all pulls the jaws i together by shifting η, then presses the middle part of r upwards and rests firmly against the cavity of the foot. Thus the central part of the skater's foot is directly supported. A pressure on the spring plate only increases the pressure between the sole and toe i, as well as between / and the heel. In the modification shown in FIGS. 4 and 5, the spring plate extends under the shoulder plate b and is bent up here in order to form a bearing for the screw g. The sole plate of the skate is made in one piece with the spring r and is slotted at the front in order to grip over the forehead support u of the running rail on which it plays freely. The projections / lie above the plates k, slide in inclined slots m of the plate r and at the same time form the heads of screw bolts which go through both the slots m and "and through the same in the plates k and are tightened with nuts" . The attachment of the skate is carried out in the same way as the previous one. By turning screw g, nut h and slide / move backwards until the latter grips the shoulder. With further rotation g goes forward and therefore also pushes r forward, so that the slits η pull the jaws i together; if the latter are finally stuck, r is pressed into the hollow of the foot. The cheek plates k go in the above-described guides ν and can be adjusted according to the width of the sole by loosening the nuts v1 etc. This adjustment is one of the first operations to be carried out when the spring plate r is pulled back against the shoulder as far as the slots m allow. In the modification shown in FIGS. 6 and 7, the spring plate r and the front plate are also made from one piece. Instead of moving the slider / by a screw, it sits at the end of a lever w; the latter is, as can be seen, slotted. A screw x, which has a collar y and a nut y1, engages through the slot, between which the lever is held. The spring plate is cut out in order to be able to reach over the screw and rests on a hexagonal collar ζ of the same. z1. is . a stop at the front of the heel plate b. In this modification, the spring plate r receives its necessary tension from the screw x. For this purpose, the lever w, which is springy and engages over the running rail with lugs w1, is rotated into the position in FIG. 7 so that it rests against z1. Further rotation retracts r as far as the slots m allow. Then you loosen the nuts y1, turn the screw χ with a wrench placed on the hexagon ζ in order to raise the spring plate r to the required height. After the plate r has been adjusted in this way, the jaws i are adjusted by means of the lever w, which rests on the projection z1, Fig. 7. To adjust the heel piece /, one latches the lever w over the running rail a, Fig 6, loosens nut y1, pushes w back to the heel, then takes off the skate again, moves lever w and heel piece f back by approx. 6 mm and pulls yl. In order to then put on the skate, one disengages w, turns it up to r1, Fig. 7, puts the foot in the skate in such a way that the heel rests against the jaws d, and then pushes the lever w inwards and latches it about a. The last movement brings / to the front of the heel, is pressed forward and pulls the plate r with it, which causes the jaws i to be tightened through the slots m, while the heel is held firmly between d and / at the same time. P ATES τ-An Proverbs: 1. The construction of ice skates with a resilient plate r which adapts to the cavity between heel and sole and which rests with its rear and front end against the clamping devices for heel and sole in such a way that after tightening the part / by screw g against the heel The nut h, movable on the running rail α, presses the plate r against the nuts f and q and by pushing the part η forward by means of slots m, pins / and plates k causes the jaws i to be tightened against the sole edges, whereby the limit of the movement of the plate r is determined by the slot ί with which it sits over t , Figs. i, 2 and 3. 2. The modification shown in Fig. 4 and 5 of the arrangement of the resilient plate r, which here at the same time forms the sole plate, in such a way that after clamping the shoulder between f and d by screw g, the latter moves forward in the nut h as it continues to rotate moves and pushes the plate r forward, to tighten the jaws ii against the sole edges by means of the inclined slots m in plate r, the projections / and plates k in guides v, and to clamp the plate r in the cavity between heel and sole. The modification shown in Fig. 6 and 7 of the arrangement of the resilient plate r, which here also forms the sole plate, in combination with the rotatable lever w, the lugs W ¹ W ¹ reaching over the running rail at one end and the other end upright part / pushes against the heel and in combination with the screw χ with nut y ¹ , collar y and collar z, by which the upright position of the plate r is adjusted, while the rotation of the lever w shifts the plate r forwards towards the Tightening the jaws i causes it against the edge of the sole.
