COMPLETE SPECIFICATION.
Improvements in and relating to Skates.
I, HERMANN KEMPER of Neu Street, Remscheir, German Empire, Skate
Maker, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention relates to improvements in skates as used upon natural or artificial
ice, and consists of an arrangement of guides, cramps or foot holds for adjusting
the skates so as to render any one pair of skates, provided with my improvements
adaptable to be attached to any size boot and used by a lady or gentleman.
The salient points of my invention consists in providing upon such skate, two
pairs of adjustable cramps or guides, one pair for adjusting the connection between
the skate and the heel and the other, the connection between the skate and the sole
of the boot of the wearer, both of said pair of cramps being operated for adjust-
ment simultaneously by the simple rotation of a screw.
In the accompanying drawings
Fig. 1 is a bottom plan or under surface view, of a complete skate according to
my invention.
Figs. 2 and 3 are side elevation and plan respectively of same.
Fig. 4 is a view of the form of key I prefer to use for operating the adjusting
screw as hereinafter explained.
I carry my invention into effect by constructing a skate consisting of a sole
plate A, connected to a skate blade B, by the means of standards C, in the usual
way,
Beneath the under surface of A is placed, transversally, a right and left hand
threaded spindle E, one end of which is formed at F to receive a key such as G
Fig. 4. The right and left handed thread upon E is caused to engage with a pair
of lugs H and H' respectively, fixed upon a pair of heel adjusting plates J J',
of which has an upstanding ridge a for gripping the heel of the boot.
each
The back ends of the plates J and J₁ are provided with transverse slots K K',
through which pass studs b, fixed to the plate A.
Upon the under surface of A, at or about the tread of the foot, is fixed a pair of
studs c and c¹ similar to band b³, and these engage with slots L and L' of a pair of
plates M and M', preferably formed as shown, and provided with an upstanding
ridged for gripping the sole of the foot, and at the back ends of M and M', are
slots N and N, which engage in like manner with studs e and e¹ upon the front
ends of the plates J, J'.
The slots L and N in M are at right angles to each other, so that if an
imaginary line be drawn through each, these would bisect each other at the point X
(Fig. 1) and so form an acute angle. The same arrangement applies to the slots L'
and N in M', in which the said imaginary lines are shewn bisecting each other
at X' (Fig. 1).
It will therefore be understood that if the key G be placed upon the end F of
the screw E, and this be rotated in the direction of the arrow Fig. 1, that both
plates J, J', may be moved in a lateral direction away from the sole plate A, to
any extent limited by the slots K, and K', which, by reason of the connecting
studs e and e¹, and the angle of the slots N and N', would draw the plates M
and M³ a corresponding distance towards the heel of the skate, and by reason of
the particular angle of the slots L and L', the said backward movement of the
plates M and M', would cause an extension of the distance between their upstanding
ridges d approximating to the extended distance between the ridges a upon J and J.

page_text: This movement is shown to its full limit by the position of M' and J' in the lower
portion of Fig. 1, and the upper of Fig. 3.
The reverse motion of the screw E would have a directly opposite effect upon
all the moving parts just mentioned, which may be carried out to any extent limited
by the slots K and K. This movement is shown to its full limit by the position
of M and J in the upper portion of Fig. 1, and the lower portion of Fig. 3.
It will thus be seen that by the simple rotary movement of the screw E, the
degree of inward or outward motion thereby imparted to the plates J and J¹ ensure
a like degree of inward or outward motion to be imparted to the plates M and M',
and by this means the skate may be adjusted to fit, and be fixed upon any size boot,
either juvenile or adult for which the skate may be intended.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that, I am aware
that adjusting plates or clamps for skates have hitherto been proposed, but these
have either been arranged for the heel, or sole only, or if for both these have been
operated separately, but not collectively by one operation as described and shown
by me, therefore, I do not claim broadly the use of adjustable plates or clamps but
what I do claim is :-
1st. The combination with any type of skate for use upon natural or artificial ice,
of adjustable heel plates or clamps, and adjustable sole plates or clamps, all operated
simultaneously and equally by the simple rotation of a screw, substantially as and
for the purposes herein described and shown.
2nd. In combination with a skate, such as ABC, the application thereto of a
pair of plates J and J', providing with upstanding ridges a and transverse slots K
and K', connected by studs band to the under surface of the heel portion of the
sole plate A; and having thereon lugs H and H', engaging with a right and left
hand threaded transverse spindle E, capable of being rotated by a key or the like G,
the studs e and e' upon J and J', engaging with slots N and N2 formed in plates M
and M' provided with upstanding ridges d and having slots L and L', through
which pass studs c and c¹ engaging with the sole plate A the whole connected,
combined, and operating substantially as and for the purposes herein set forth and
shown by the accompanying drawings.
