Patented May 10, 1949 UNITED STATES, PATENT OFFICE ICE AND SNOW SKATE Gottlieb Triichslin, Basel, Switzerland Application November 28, 1944, Serial No. 565,531 In Switzerland December 3, 1943 Claims. 1
This invention relates to snow and ice skates to be attached to shoes, mainly composed of an intermediate runner connected with a supporting surface projecting on each side, whereby the supporting surface and also the runner projecting therefrom in a downward direction are uniformly bent upwards in the front part, the head of the skate being provided with a downwardly effective device for the forward movement of the skater. The width of the running surface of the runner should advantageously and approximately correspond with that usually employed in ice skates and, at most, it should only project out of the supporting surface to an extent corresponding with its width.
According to the present invention, it is possible to run on ice and on snow. When skating, merely the runner takes effect. In this case, there is no principal diiference, as compared with skating by means of skates usually employed, However, in the case of snow, the runner takesa cutting effect. Therefore, the supporting surface is located on the snow in such a manner that extensive sinking into snow is prevented. However it is possible to run on a surface of snow, due to the supporting surface being upwardly bent in its front part, similarly to the pointed end of a ski. such a manner that each half of the supporting surface has an outwardly rising form, the'supporting part of the supporting surface will automatically, according to the consistency of the snow, adapt itself to the existing relation of force, inasmuch as, in the case of hard snow, only a more or less narrow zone of the supporting surface on both sides of the runner lies on the snow,
If the supporting surface is formed, in
whereas the outer zones of the supporting surface project above the snow.
It is an object of the present invention to provide each half of the supporting surface in a form which resembles that of a vault or arch; It
is also possible to provide a supporting surface of a shape which in cross section has the general form of the letter V. The above mentioned shapes are not only advantageous when the skate is used for running on snow, but also for skating on ice, because the upwardly curved supporting surface does not, in any way, interfere with the setting on edges, when running along curves on ice. In other words, the outer edges of the supporting surface will not contact the ice surface when the skate is tilted as it is usually done when running along curves. The ice and snow skates hitherto known have straight or plane rather than curved or arched supporting surfaces so that said known skates have the disadvantage that their supporting surfaces contact the ice surface when the skater runs along curves on ice. Another advantage of the vaulted or curved supporting surface over a straight or plane supporting surface in this type of skates is that the skate when used for running on snow penetrates the snow only to the extent necessary to support the weight of the skater, while straight or plane supporting surfaces always contact the snow surface with their entire area.
The supporting surface may be composed of an integral piece, the runner then being advantageously attached to its lower side. Instead of this construction, each half of the supporting surface may be made of a separate piece. In this case, each half of the supporting surface will be attached to one side of a traverse, which either carries the runner on its lower part, or is formed as a runner. Each half of the supporting surface may be subdivided, composed of two or more 1ongitudinally directed single strips. They may be arranged at a certain distance from each other, and they should advantageously be held by a mutual support. These strips may have a curved form, whereby the entire supporting surface would be composed of runners positioned at a certain distance from each other and directed longitudinally, whereby these runners are located symmetrically with respect to the central runner.
The accompanying drawings show, by way of illustration, an example of the present invention in which Fig. l is a longitudinal sectional view of the skate,
Fig, 2 is a top plan view,
Fig. 3 is a cross section through the rear bootattaching device, taken on line AB of Fig. 1.
According to Figs. 1 and 2, al represents the central, longitudinal portion of the supporting surface, I) designates the runner mounted thereon which is approximately as high as the width and projects downwardly from the supporting surface. As shown at the left of Figure 1, the front portion of said runner b is curved upwardly in the same manner as the supporting surface al. Just in front of the point of transition of the substantially straight runner portion and the curved runner portion, the runner edge is provided with downwardly directed dents or teeth bl, which provide for gripping action on ice. An edge-part a2 is located adjacent to each side of the central supporting surface at, This edge-part is attached to the central part an by means of screws or rivets a3. The central Supbe made of one piece with the supporting surface. I L
The head-part a6 is provided with a device for forward movement, this device being composed of 2 steel ledges cl and 02. The steel ledge.
cl, as shown in Fig, 2, is only provided across the central fiat bent part al of the head of the device, whereas the second ledge c2, positioned in front thereof, is provided with flanks projecting beyond;
it, which, in horizontal section, show a curved form c6 with a sharp turn 03 towards the rear.
ledges are mounted on the supporting surface bymeans of scr ews c3 screwed in the front or edge of said supporting surface. The ledge cl is provided with sharp, downwardly direste dents or teeth 04, whereasthe ledge 02 shows a "sharp lower edge of thin steel plate. Therefore, any further sharpening is not required. Directly behind the device for the forward movement, the supporting surface, and particularly its U central part al on' both sides of therunner b, is provided with apertures (14; Their object is to prevent accumulation of snow, inasmuch as evidently, as shown in Fig. l, snow could be squeezed into the acute-angled cornerbetween the central supporting'surface 'al and the ledge cl for the forward movement, when the device for the forward movement is set into action. "By means of these apertures 14, snow permitted to break its way through upwardly, whereby it is automatica-lly discharged.
Ilie'rear part of the supporting surface is clevelbp'ed 'or merges to a point a 9 ,'j as shown in Fig. 2. This enables excellentrunning onsn ow, beides straight stepping and, furthermore, it facilitates steering possibilities. In order to reduce running resistance, the centrai supporting surface oi is provided with strearniined indentations a5 in the front bend, whereby the form of these indentations should be selected according to,
streamlined requirements. The indentations have resistance-reducing properties similar to the indentations'in the bows of ships on both sides of the keel-line. -'-The device for the attachment of boots isCQmposed of a front all] and a rear part al I, similar to skates. The front part serves for the c' ception of the boot sole, the rear part for that of the heel. For this purpose, tin or sheet metal plates dl are provided which, by means of the angle pieces d2, rest on the central supporting surface al, screws or rivets d3 mounting the plates dl on the angle pieces d2. Angular clamps M, as used in conventional skates, are supported in sliding guides d5 on each side of said plates all, capable of being laterally inserted and pushed out. They are arranged to project downwardly into the supporting angle piecesdZ and are provided with a female screw thread, with which they run on the fixing bolt 116, provided on oneside with a square portion 011, capable of being engaged and turned by a regular key. The screw is supported in the central counter part do, which is attached to the plate dl by meansof rivets.
The use of this new skate is readily apparent from the foregoing description. By attaching a skate to each boot the usual technical skill is applied as with conventional skates. The shape of the runner corresponds to that of the conventional skates. The dents bl for grippin action on ice and the devices 02 and 04 for gripping action on snow facilitate the forward movement. The rear. end pf the runner ,(see Figure 1) may be used as a brake, as it is adapted to cut into the ice with sharp edges. If snow conditions are favorable, the ledge 02 may be used as brake. In this event, only the ledge 02 becomes active, because only said ledge 02 is pressed into the snow shoving the snow forward, when the bootdstipped for braking. When running on snow under normal conditions, the ledges c2 and cl are above the snow surface. If the snow is yerysoft and loose, its consistency is decreased and the ledges c2 and al may somewhat penetrate the snow. However, the resistance of-softand loose snow is relatively small, so that the penetration of the ledges c2 and cl into the snow does neither considerably brake the skate nor otherwise unfavorably affect its running ualities. The ends 08 of the ledge :2 are curved anddirected towards the rear of the skate to decrease the resistance of the skate when said ledge 92 contacts the, snow. If the snow layer is hard, as in the case of old and frozen snow, the skate only sinks to asmall extent, whereby the central supporting surface a! is partly fully pressed into the snow, the edge-parts a2, however, act as stabilizing surfaces and render safe running possible,
* especially when running curves.
