COMPLETE SPECIFICATION filed by the said Herbert John Haddan at the
Office of the Commissioners of Patents on the 23rd October 1880.
HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
"IMPROVEMENTS
Patents, of 67, Strand, in the City of Westminster, Civil Engineer.
IN SKATE ATTACHMENTS." A. communication from abroad by Charles Brewster,
of Montreal, in the Dominion of Canada, Dental Surgeon.
This Invention has reference to further improvements in skate attachments to
those for which Letters Patent of Great Britain were granted on the 10th day of
March, A.D. 1876, under Number 1126, to cause in some respect a more desirable
action of the attachments, and in another, or in others, a cheaper form of
construction.
In the Drawings hereunto annexed, similar letters of reference indicate like parts,
and
Figure 1 is a side elevation of a skate embodying my Invention; Fig. 2 is a plan
of front end of skate right side up; Fig. 3 is a plan of front end of skate upside
down, with runner removed; Fig. 4 is a plan of heel end of skate right side up;
Fig. 5 is a plan of heel end of skate upside down.
Fig. 1 is shown on a somewhat smaller scale than the other Figures, which are
about full size of a man's skate..
Letter A is the runner of the skate, provided with three projections B, C, and D,
for attaching the plates to, the front plate being attached to C and D by brackets
E and F, one side of each bracket being riveted to the runner, and the other to the
sole plate A'. The brackets E are furthermore arranged to form guides to a
T shaped slide G, as will be clearly understood from Figs. 1 and 3; this slide has its
front edge H turned up at right angles, and portions I of the under side of the top
bar of the T also turned up at right angles, whereby said top bar is converted into

page_text: a groove for holding and guiding the shanks of the clamps K; L is a slot cut in
the body of G for the projections C to pass through, and of sufficient length to
allow the G to have all the necessary inotion. In the shanks of each of the
clamps K, a stud M, having a button head, is secured; the body of this stud
comfortably fills inclined slots N in the sole plate on the one side of the shank of
the clamps, and on the other side transverse slots O cut in G on the other side;
its extremity is provided with a washer P, over which the end of M. is riveted,
thus forming a button or flange head on the under side. R is a standard riveted
into the T-slide G, having a screwed hole in it to agree with the screwed spindle B³.
The sole plate is provided with a depressed portion C², so that the button head of
M shall not stand up above the remaining portions of the surface of the sole plate,
and thus prevent the sole of the boot from resting fairly upon them. It will
therefore be seen that as the T shaped slide G is moved backwards and forwards,
the clamps K are caused, by the action of the studs M, to be drawn in and pushed
out to grip or release the sole of the boot placed upon the plate A¹. Furthermore
it will be seen that as the slide G is moved towards the heel, they (the clamps)
move inwards to grip the boot, which is an important improvement, for it must be
remembered that the front part of the boot from the tip of the toe tapers for a
considerable distance, becoming larger as it approached the heel, so that by thus
taking advantage of the form of the boot, a larger range of size of boot for the
same skate is provided for, as well as causing the fastening and unfastening of the
clamps to be more quickly accomplished. The projection B is provided with a
recess at D², for the reception of a plate E3 (the section of B, shown in Fig. 5, is on
line, Fig. 1), which is simply cut to fit, and then put in place in the recess; the
heel plate I is provided with openings to fit corresponding projections F3 formed
on B, and these projections are entered into the opening in the heel plate and
riveted over, when the whole is secured together, the plate E² forming a guide, and
the riveting an attachment, the whole forming a much cheaper and better guide
than any of those at present in use for the heel clamp slide K³.
It will be seen that the stationary and front clamps L' for the heel are made in
one with the plate 12, while the clamps M2 for gripping the rear of the heel are
made in one with the slide K². N2 is a standard riveted to the slide K³, and forms
a bearing to receive the journals and collared end of the spindle B2 to revolve in
(see Fig. 5). The slide K³ is so clearly shown the the Drawings that no further
description of it is considered necessary. On the spindle B² a windlass head S is
secured, by which, with the finger and thumb, the spindle is rotated.
What I claim and wish to secure by Letters Patent is as follows:-
1st. The combination of the plate A, having inclined slots N, slide G having
slots O, and clamps K having studs M, with an operating devise B²; substantially
as set forth.
2nd. The combination of the spindle B2 having windlass head S with slide G,
constructed and arranged as described, to operate in conjunction with plate A' and
clamps K, constructed and arranged as described, and with slide Ks also constructed
an arranged as described, the whole substantially as set forth.
3rd. The combination of the projection B, having recess D³, plate E², heel
plate 13, and slide K², substantially as and for the purposes set forth.
In witness whereof, 1, the said Herbert John Haddan, have hereunto set my
hand and seal, this Twenty second day of October 1880.
