Improvements in Skates.
I, NEWNHAM BROWNE, of 73 Cheapside, in the City of London, Chartered
Patent Agent, do hereby declare the nature of this invention which has been
communicated to me by Hermann Wirths and Sohn, of Remscheid, Rhenish
Prussia, in the Empire of Germany Merchants and Manufacturers, to be as
follows:-
This invention relates to skates of the kind having a metal stock with adjustable
jaws by which the boot is gripped.
In such skates hitherto in use more or less difficulty occurs in obtaining an equal
and uniform pressure between the front and the back jaws or fastenings
respectively and considerable trouble often occurs in adjusting them.
Now this invention provides an arrangement of parts comprising two pairs of
jaws by which the pressure of the front and back pair is mutually interdependent,
so that an excess or deficiency of pressure by one pair over the other cannot occur
and the skates are thus fixed with great facility firmness and security, to the
boot.
According to my invention two pairs of jaws are provided, one pair to grip the
front part and the other pair to grip the heel of the boot, such jaws forming part
of, or being carried by levers, the members of each pair of which are jointed
together under the central portion of the foot and such levers are operated by a
right and left screw respectively on a spindle placed longitudinally under the
central line of the foot and by oblique slots or surfaces working on or against
studs, or in or against which studs work, or by link connections, in such wise that
the approach towards, or recession from, each other of two threaded eyes working
on the right and left screw of the spindle respectively cause the levers and jaws to
close in or open accordingly.
The said threaded eyes may conveniently be attached to and made to operate,
one of them the jointed ends of one pair of levers, and the other, a pair of movable
studs, or equivalents, controlling the other pair of levers.
The sole plate may conveniently be fitted with a rim or flange at the back to
partly encircle and hold or support the heel of the boot.

Improvements in Skates.
I, NEWNHAM BROWNE, of 73 Cheapside, in the City of London, Chartered
Patent Agent, do hereby declare the nature of this invention, which has been
communicated to me by Hermann Wirths and Sohn, of Remscheid, Rhenish
Prussia, in the Empire of Germany, Merchants and Manufacturers, and in what
manner the same is to be performed to be particularly described and ascertained.
in and by the following statement :-
This invention relates to skates of the kind having a metal stock with adjustable.
jaws by which the boot is gripped.

page_text: In such skates hitherto in use more or less difficulty occurs in obtaining an equal
and uniform pressure between the front and the back jaws or fastenings respectively
and considerable trouble often occurs in adjusting them.
Now this invention provides an arrangement of parts comprising two pairs of
jaws by which the pressure of the front and back pair is mutually interdependent,
so that an excess or deficiency of pressure by one pair over the other cannot occur
and the skates are thus fixed with great facility, firmness and security, to the
boot.
According to my invention two pairs of jaws are provided, one pair to grip the
front part and the other pair to grip the heel of the boot, such jaws forming part
of or being carried by levers the members of each pair of which are jointed
together under the central portion of the foot and such levers are respectively
operated by a right and left screw on a spindle placed longitudinally under the
central line of the foot and by oblique slots or surfaces working on or against studs
or in or against which studs work, or by link connections in such wise that the
approach towards, or recession from each other of two threaded eyes working on
the right and left hand screws of the spindle respectively cause the levers and jaws
to close in or open accordingly.
The said threaded eyes may conveniently be attached to and made to operate,
one of them the jointed ends of one pair of levers, and the other, a pair of movable
studs or equivalents, controlling the other pair of levers.
The sole plate or the back portion thereof may conveniently be fitted with a
rim or flange at the back to partly encircle and hold or support the heel of the
boot.
In the accompanying sheets of drawings
Fig. 1, is a side elevation of a skate according to this invention-Fig. 2 is a plan
of the same,
Fig. 3, is a back end elevation with the jaws fully extended.
Fig. 4, is a plan of the underside with the jaws fully extended.
Fig. 5, is a similar plan of the underside with the blade removed and the jaws in
their closed positions.
Fig. 6, is an underside view of the front pair of jaws shewing the mechanism by
which one of the jaws is made adjustable for centering the skate on the boot.
Fig. 7, is a plan of a similar skate but with the foot plate made in two parts for
the sake of lightness.
A is the foot plate. B is the blade. C is a spindle, on which are cut a right
and left handed crew c¹ and c2 respectively and having at the rear end a square
end by which it is operated by means of a key. D is a threaded nut working
on the left handed screw c³, and operating the front pair of jaws J J'.
E is a
threaded nut working on the right handed screw c¹ and operating the rear pair of
jaws F F.
The back pair of jaws F F are jointed together on a pin f fixed in the foot plate
and each jaw has an oblique slot G in which a ping forming part of the nut E
works. H H are pieces attached to the jaw by rivets h on which they are free
to move sufficiently to enable them to adjust themselves to the edge of the boot.
The front jaws JJ' are jointed together on a pin forming part of the nut D
and each jaw has an oblique slot K K through which is a fixed pin k riveted into
the foot plate A. To provide for any onesidedness in the sole of the boot and to
enable perfect centering of the skate on the foot to be obtained, the jaw J' is made
longer than its fellow, and the slot K therein is also made longer, and an adjustable
piece Lis secured thereon by a screw nut m and by a guide rivet n in a slot n'.
By loosening the nut m the piece L which carries the toothed part o of the jaw
may be slid backwards or forwards within the limits of the slots, thereby adjusting
the toothed part o of the jaw farther from or nearer to the central line of
the skate as may be required by the shape of the boot to which it is to be
attached. The jaw J is bent at so as to allow the piece L to lie in the same
plane as that part of the jaw J' nearer to its joint. The rotation of the spindle C

page_text: carries the nuts D and E farther apart or nearer together according to the direction
in which it is turned, and the pins g g on the nut E are thereby carried backwards
or forwards in the slots G G whereby the jaws F F are opened or closed. P is a
rim or flange forming part of or fixed to the foot plate A and serving to support
and hold the heel of the boot and lessen the strain on the jaws.
By the same rotation the nut D is carried forwards or backwards and the
jaws J and J' are made to slide on the pins kk thereby causing them to open or
close.
It will be seen that the longitudinal motion of the spindle C is governed entirely
by the nuts D and E and hence if either the front or back pair of jaws, when the
skate is being put on, close on the sole of the boot before the other pair, the nut
connected with that pair of jaws remains stationary, while the nut connected with
the other pair of jaws moves, until both pair press equally on the sole of
the boot.
Having now particularly described the nature of this invention and in what
manner the same is to be performed as communicated to me by my foreign
correspondent I declare that what I claim is
1. The improvements in skates whereby the pressure of the two pairs of jaws on
the sole of the boot is equalized substantially in the manner hereinbefore
described.
2. In skates the arrangements of parts comprising two pairs of jaws by which
the pressure on the front and back pair is rendered mutually interdependent
substantially as described.
3. The improvements in skates consisting of a spindle part of which is threaded
with a right handed and part with a left handed screw operating two nuts the
varying distance between which causes the opening or closing of the jaws sub-
stantially in the manner and for the purpose hereinbefore described.
4. The improvements in skates hereinbefore described and shown in the
drawings.
5. An improved skate having a spindle C with a right and a left handed
screw and thereon operating nuts D and E and jaws F F, and J and J'
with oblique slots G G K K substantially as described and shown in the
drawings.
