ADJUSTMENT FOR SKATES."
"A NEW LEVER
This Invention relates to the construction of a lever adjustment for skates. The
adjustments hitherto used for fastening a skate to the foot of a skater are more or
less complicated, and in consequence rather expensive. The adjustment to which
this Invention relates is quite simple, it is easily manipulated, and while fastening
the skate most completely a cheaper and better article may be produced by applying
the same than heretofore.
The said Invention is carried into practice as follows, that is to say-The lever
adjustment is arranged underneath the sole of the skate, and is composed of the
following parts:-1st, of peculiarly shaped sole cramps; 2nd, of a lever having spring
power of its own; 3rd, of an adjusting piece fastened to the heel cramp; 4th, of an
adjusting slide with nut. Each of the sole cramps glides on a screw in a cut in the
sole of the skate; these cuts are curved to some extent, running obliquely towards
the front of the skate in the direction of the runner. In the middle part of the
sole they are united, binge-like, by means of a rivet gliding in an elliptic cut of the
sole, being by the same means united with the front part of the lever.
Underneath the lever a little behind the said rivet an adjusting slide is fastened,
gliding in an elliptic cut in the adjusting piece. This adjusting piece is fastened to
the adjusting slide by means of a nut which is screwed upon the screw thread, being
the downward prolongation of the adjusting slide.
Before being used the cramps of the skate must be adjusted with regard to the
boots or shoes of the skater, as is done in using the so-called "Halifax" skate. This
regulation is effected by fixing the adjusting piece.
When the skate is to be used the lever is turned rectangularly to the runner, and
is pressed backwards as far as possible, thereby the rivet uniting the sole clamps glides
backwards in the cut in the middle part of the sole; the sole cramps in consequence
glide to the outside in the oblique cuts in the sole, and open in their entire width.

page_text: If the lever gets turned back the adjusting piece presses the heel cramp in a back-
ward direction, whilst at the same time, by the adjusting slide fastened by a nut,
the rivet gliding in the cut in the middle part of the sole is pressed forward. The
sole cramps connected to this latter are pushed forward, likewise pressing at the
same time toward the inside in consequence of their gliding in the oblique cuts in
the sole.
A kind of a pin is fixed to the after part of the lever, catching by means of the
spring power of this latter into an incision in the under side of the sole, and thereby
holding fast the entire mechanism.
When the skate is to be taken off the foot the lever is pressed out of the said
incision, and after turning the same rectangularly to the runner the skate is shaken
off the foot.
This Invention is intended to be applied to skates of all kinds, including roller
skates.
