page_text: I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex 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 :-
The invention relates to an improvement in that class of skates in which clamps
are employed to secure the skate to the boot or shoe without the aid of straps and the
invention consists in certain details of construction hereinafter fully described and
set forth in the claims.
Referring to the accompanying drawings
Fig. 1, represents a side view of a skate embodying my invention.
Fig. 2, is a plan or top view of the same with the clamps and actuating lever in a
closed position.
Fig. 3, is a similar view with the clamps and actuating lever in an open position.
Fig. 4, is a transverse vertical section taken on the line a, a, of Fig. 2.
Figures 5 to 24, are detail views of various parts of the skate.
A, represents the skate runner; B, the toe plate; C, the heel plate; D, tho
actuating lever; E, E, the toe clamps; F, a screw threaded regulating bar; and G,
the adjustable heel clamp.
The runner A, is of about the same height at the toe as at the heel (see Fig. 5)
whereby I am enabled to cut the runner from a much narrower bar than used for
runners of ordinary construction. The upwardly projecting toe portion a, is provided
with a recess b, of hook form as shown, and both the centre and heel projecting
pieces c, d, are provided with a recuss e, and the heel projecting piece d, is also
provided with studs or projecting pieces f, f.
The toe plate B, is made of thin metal stamped out and bent to the form shown
(see Figs. 6 and 7) which are respectively side view and plan of the plate, near the
forward end a hole y, is cut, and at the rear end is formed a channel h, for the toe
clamps E, to slide in. This channel is slightly curved transversely of the skate to

page_text: allow for the curve of the boot or shoe; and in the centre of this channel a depression i,
and two holes j, j, are formed; a round hole k, is also made on one side near the
centre as shown.
To build up from the front projecting piece a, of the runner to the front of the toe
plate, I employ a small piece of metal H, stamped to the shape shown in Fig. 8, and
then bent to the form shown in Fig. 9.
The toe plate is secured to the runner in the following manner: the piece H, is first
placed in the hooked recess b, in the runner, the toe plate is then hooked on to the
top of the piece H, the upper ends of which pass through the hole g, the rear end of
the toe plate is then passed over the centre projecting piece c, of the runner A, the
depressed portion i resting on the bottom of the recess e; a flat key I, of the form
shown in Fig. 10 is then dropped into the depression, and turned a short distance
which brings its projecting edges into the notches e', in the projecting piece c, thereby
securely locking the toe plate on to the runner.
The heel plate C, is also made of thin metal stamped out to the form shown in
Fig. 11 and then bent to the form shown in Figs. 13 and 14 which are respectively
side view and plan of the heel plate; the outer edge of the portions 1, which form
the rear heel clamps is thickened and slightly bent up in the stamping so as to form
the spur as will be best seen in Fig. 12, which is a section taken on line y, y, of Fig. 11.
The heel plate is also provided with a depression i, and holes j,j, and it is fastened to
the runner by a key I, in the same manner as that described with reference to the toe
plate; it is also provided with a long slot m, in which slides the adjustable heel
clamp G.
The toe clamps E, are stamped and bent to the form shown in Figs. 15 and 16
which are respectively side view and plan of one of the toe clamps; the spur on these
clamps is formed when they are stamped out the same as described with reference to
the heel clamps, and each of these clamps are provided with a small stud n; they are
also made slightly curved longitudinally so as to conform to the shape of the curved
channel, in the toe plate B, in which they slide.
The actuating lever D, is stamped and bent to the form shown in Figs. 17 and 18
which are respectively side view and plan of the lever. The portion of this lever
upon which the sole rests is curved longitudinally to follow the curve of the boot or
shoe, and in the wide or front portion are formed three slots p, q, q. Through the
straight slot p, is passed a bolt J, (shown dotached in Fig. 19) which also passes
through the hole k, in the toe plate and is secured by a pin s (see Fig. 1) passing
through a hole in the bolt just under the toe plate B. This bolt forms the fulcrum upon
which the lever 1), swings. The studs n, n, on the toe clamps E, pass up into the slots 9, 7,
which are on an angle to each other in the form of a V, and are each curved slightly
at one end as shown. The tail end D¹ of the lever is formed saddle shaped to fit over
the upper edge of the runner to lock the lever when in a closed position.
The lever B, is also provided with a hole, through which is passed a headed block
or bolt K (shown detached in Fig. 20) provided with a screw threaded hole through
which the screw threaded regulating har F, passes; this bar is at its other end secured
to the adjustable heel clamp G, (see Figs. 21 and 22) which are respectively a plan
view and end view of the bar and clamp. The bar F, is also provided at the end of
the screw threaded portion with a thumb piece w, which when the lever D, is in the
locked position comes against the edge of the lever and prevents the rod F, from
turning.
The clamp G, is stamped out and bent to the form shown, the lower portion forming
a button t, which is passed through the slot mn, in the heel plate before the bar F, and
lever D, are connected together, the portion of metal that was on each side of the
button ¿, being bent up forms a rest or support on the top of the heel plate and the
upper edge of the clump is bent over to form a knife edge.
To strengthen the ton and heel clamps l, I form a bulb or depression at the centre
where they are bent up as shown in Figs. 23 and 24 which are respectively side view
and section through a clamp and a portion of the heel plate. This bulb or depression *,
acts as a brace and prevents the clamp from being broken off..

page_text: To secure the skate to a boot or shoe the heel clamp G, and toe clamps E, E, are
first adjusted to the required size by turning the regulating bar F; the skate is then
placed on the boot or shoe iu un open position as shown in Fig. 3, then upon pressing
the lever D, inwards the heel clamp G, comes into contact with the heel of the boot
or shoe and as the lever is pressed further in it is also pushed forward, the clamp G,
acting as a fulcrum and the too clamps E, E, are drawn inwards by the studs n,
working in the slots q, being drawn towards the inner ends of the slot
which are
set at an angle to each other in the form of a V as shown.
9,
It will be seen that the fulcrum J, is on one side of the centre of the skate, viz. on
the side the levers open whereby the toe clamps are caused to open and close in
unison with each other.
Having now particularly described and ascertained the nature of the said 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 :-
