Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CARRON, of Birmingham, in the County of Warwick, Lathe Maker, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-first day of December, in the fifth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
William Carron, Her especial licence, full power, sole privilege and authority,
that I, the said William Carron, my exors, admors, and assigns, or such
others as I, the said William Carron, my exors, adiñors, or assigus, should
at any time agree with, and no others, from time to time and at all times
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF
CLOGS AND PATTENS;" in which said Letters Patent is contained a proviso,
that I, the said William Carron, shall cause a particular description of the
nature of my said Invention, and in what manner the same is to be per-
formed, to be inrolled in Her said Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto hnd
will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Carron, do hereby declare that the nature of my Invention, and
the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, reference being
had to the Drawing hereunto annexed, and to the figures and letters marked
thereon (that is to say) :-
My Invention relates, first, to a mode of constructing clogs, by combining
a thin flexible metal sole with a divided tread for the fore part of the foot.
Secondly, to a mode of constructing clogs by a peculiar combining of a
flexible metal sole with the fore part of the tread.
Thirdly, to a mode of combining a flexible metal sole with the heel of a
clog, in order to allow of the clog expanding.
Fourthly, to a mode of making the leather caps for the toes of clogs and
pattens.
And, fifthly, to a mode of constructing the iron treads of pattens.
And in order that my Invention may be fully understood and readily carried
into effect, I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
1
Figure 1 represents. a side view of a clog constructed according to part of
my Invention; Figure 2 is a plan thereof. a, a, is a thin plate of metal, by
preference of tempered steel. The heel 6 is affixed thereto by rivetting or
otherwise, and the back leather c is fastened to the heel, as is shewn. The
fore part d, e, f, is made of separate parts of wood or leather, or other suitable
material, and the parts d, e, f, are rivetted or otherwise affixed to the plate
a, a, so that the flexibility of the plate may allow of the fore part of the tread 2
bending between the parts d, e, f, and it is this peculiarity which constitutes.
this part of the Invention.
Figure 3 and Figure 4 shew two side views of a clog constructed according
to the second part of the Invention; and it will be seen, that although the
tread d is of some length, the plate a is only affixed at the fore part; so that. S
the plate a may bend in walking, notwithstanding the length of the tread;
and it is this peculiar mode of affixing the plate to the tread only at the fore
part that constitutes this part of my Invention.
Figure 5 shews a plan of a clog constructed according to the third part of my.
Invention, and consists of a mode of obtaining an expanding clog when a thin 3
flexible metal plate a, a, is used; and the improvement.consists in the manner
of attaching the heel to the plate a, there being slots g, g, formed in the plate;
and there are screws or other instruments with beads, which, passing through

page_text: the slots, are affixed in the heel b; and there is a spring h affixed to the under
side of the plate a, and there is a recess formed in the heel to receive the
spring. By this arrangement the heel will at all times have a tendency to
remain at the shortest length, but may be extended by the sliding of the plate
a in respect of the heel, and when on the foot the clog will attach itself better
than ordinary clogs.
I will now describe the fourth part of my Invention, which consists of
forming the caps of the fore parts of clogs and pattens, and consists in forming
them in tools without cutting the leather of which the toe caps are formed. I
sink a cavity (by preference in. iron, though wood or other hard materials
may be used), such cavity being of the form of the exterior of the too cap of a
clog or a patten, and I. make. another tool or "force" convex, of the form
and size of the interior of the caps; the leather is to be cut into a suitable size
and immersed in warm water, and when in a soft state it. is to be. taken out.
and rubbed over with "dubbing" (oil and grease), the leather. is then placed.
over the concave mould, and the convex tool forced in, compressing the leather
between the external surface of the convex. tool. and the inner surface of the
concave mould. The leather is to remain in the tools till sufficiently cold, and
may then be japanned as leather is usually japanned. In constructing the
irons of pattens, it has been usual to make them of rings, the lower surface of
which on coming to the ground rests on the same plane.
Now, the object of the fifth part of my Invention is to apply irons to the
fore parts of pattens, which shall be highest towards the back ends thereof,
and at the front end approach the toe with curved surfaces, by which means
the person using such pattens will be materially convenienced in walking.
Figure 6 shews an elevation, and Figure 7 a plan, of a patten according to
this part of my Invention. z, z, shew the two surfaces which constitute the
fore metal tread of the patten, and it will be seen that the tread is highest at
the back end at y, y, and at the fore part the tread approaches the toe of the
patten with a gentle curve, as is shown, by which arrangement the person in
walking will find great convenience.
Having thus described the nature of my Invention, and the manner in which
the same is to be performed, I would have it understood that what I claim is,-
First, the mode of constructing clogs, by combining a flexible metal sole
with divided treads at the fore parts of the clogs, as above described.
Secondly, I claim the mode of constructing clogs, by a peculiar combining
of a flexible metal sole, with the fore part of the tread, as above described.
Thirdly, I claim the mode of combining a flexible metal sole with the heel
of a clog, in order to allow of the clog expanding.

page_text: Fourthly, I claim the mode of making leather caps for toes of clogs and
pattens, as above described.
And, fifthly, I claim the mode of constructing the iron treads of patterns,
by forming them of a curved surface in front, as above explained.
In witness whereof, I, the said William Carran, have hereunto set my
hand and seal, this Twenty-first day of June, in the year of our Lord
One thousand eight hundred and forty-two.
