IMPROVEMENTS IN THE CONSTRUCTION OR MANUFACTURE OF CLOGS AND PATTENS, OR SUBSTITUTES FOR THE SAME
Year: 1826

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPHI
SCHALLER, of Regent's Street, in the County of Middlesex, Ladies' Shoemaker,
send greeting.
WHEREAS His most Excellent Majesty King George the Fourth, by His
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Sixth day of May now last
past, did grant unto me, my executors, administrators, and assigns, His special
licence, full power and authority, that I, the said Joseph Schaller, my executors,
administrators, and assigns, during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales, and
Town of Berwick-upon-Tweed, my "IMPROVEMENTS IN THE CONSTRUCTION OR
MANUFACTURE OF CLOGS AND PATTENS, OR SUBSTITUTES FOR THE SAME;" in which
Letters Patent there is contained a proviso obliging me, the said Joseph
Schaller, under my hand and seal, to 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 His Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said recited Letters
Patent, as in and by the same, relation being thereunto bad, may more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Schaller, do hereby declare that my said Invention of certain Improve-
ments in the Construction or Manufacture of Clogs or Pattens, or Substitutes
for the same, is fully described and ascertained as follows, that is to say :-

page_text: My Invention consists in adopting a contrivance or means by which the
clog or patten may be lengthened or shortened, and the heel widened or
narrowed at pleasure, to fit boots or shoes of different sizes, and to an im-
provement of the slide affixed to the side of the clog or patten, which
improvements are more particularly ascertained by the Drawings hereunto
annexed, and the following description thereof. I do not consider my Invention
confined to the precise means of lengthening and widening the clog or patten,
or the heel thereof, exhibited in the Drawings, which aro delineated as
examples by which my Invention may be carried into effect; and of course I
substitute iron, leather, cork, or any other suitable material for their manu-
facture, instead of wood and brass, when desired.
Figure 1 in the Drawings annexed represents a clog in perspective, with my
improvements for elongating or contracting the clog or patten agreeably to one
mode of accomplishing the same, namely, under the brass plate at A is a sliding
rack and spring, or other contrivance, which enables the clog to be elongated or
shortened. At B is another rack and spring, or a screw or other contrivance,
which allows the sides of the heel piece to be contracted or expanded breadthwise.
At C is shewn the improved slide, which permits the strap to which it is attached
to be lengthened or shortened at pleasure. A particular description of these
several contrivances is herein-after set forth and explained with reference to
other Figures in the Drawings, which shew the material parts of the said
contrivance. Figure 2 exhibits a plan of the sole of a clog or patten, in which
the brass cover or sheath and plate are removed, which are shewn separately
-at-Figures-3-&-4.-Figure 5 represents a perspective view of another kind
of clog (more especially adapted for ladies' wear), in which another mode of
lengthening and shortening the sole is employed. This Figure shews a clog
drawn out to its full extent from the cross, line W. Figure 2 shews a clog
drawn out in part. Figure 1 shows a clog contracted to its least extent.
The methods by which a clog or patten may be lengthened or shortened, or
the heel narrowed or widened, are very numerous. I shall therefore confine my
description to three methods or contrivances for lengthening and to two methods
of widening the same, as being sufficient to explain the nature of my Invention.
Figures 6 and 7 represent one of these methods (that which is supposed to be
applied to the clog Figure 1). Figure 6 is a plan, and Figure 7 an edge view
of the same contrivance, the same letters have therefore reference to similar.
parts in each of the Figures. The rack or notched brass plate d is screwed.
at e to the waist of the sole, and the spring catch f is screwed or rivetted at g
to the heel piece of the clog. A cavity is therefore made in the clog, to allow
these parts to act without obstruction. They are so fixed as to rest in contact

page_text: in the manner shewn in the Figures, with the brass pin h (which is rivetted
to the spring catch f) passing through the slot mortice i, in which it slides
backward or forward as the clog is lengthened or shortened. By this
arrangement it will be seen that the clog may be contracted by simply thrusting
the toe part towards the heel, as the spring catch which is fastened to the
former slides over the notches in the rack, but to pull the toe from the heel
of a clog, in order to lengthen it, it becomes necessary to press upon the
extremity of the brass pin, which in the clog protrudes a little way through
the brass case for that purpose, as shown at j in Figure 1.
The Diagram, Figure 8, is intended to elucidate another method of elongating
and shortening a clog (that which is supposed to be employed and represented in
part by Figure 5). In this instance an iron plate k, perforated with holes, as
shewn, is fastened by a pin or rivet to the fore part of the sole and kept steady
in its position by two pins m, m. The other end of the perforated plate is
formed into two hooks or horns, which prevent it from being drawn entirely out
from the morticed cavity n of the heel, wherein it is slidden backward or
forward at pleasure) by the hooks coming in contact with two pins or rivets,
which pins and rivets are also used to fasten down a plate iron stay o. The
brass pin p is employed for fixing the clog at the required length. For this
purpose the brass sheath q (Figure 5), which goes entirely round the clog, and is
formed into one piece, has a hole perforated through the upper part, as at r, and
another through the bottom, directly opposite the pin p, being then passed through
both holes in the brass sheath, and through one of the holes in the intervening
perforated sliding iron plate k, fixes the clog firmly at the length required.
A third method of elongating or shortening a clog is shewn by the plan,
Figure 2. s is a rack, one end of which is inserted into and screwed fast
to the waist of the clog t. To the heel of the clog is fixed a spring catch
u, the tooth or hook of which enters the notches of the rack. The spring u
is strengthened in its action by another curved spring v. To the hook or tooth
of the spring u is fixed a screw as a handle to raise or push the catch out of
the rack when the latter is to be moved. The stem of this screw passes
through the slot mortice w of the brass sheath, Figure 3, when the latter is
fixed in its place on the clog. The pushing back of the spring u; by means
of this screw, enables the rack to be slidden forward or backward, elongating
or shortening the clog thereby.
.
Of the various methods by which the heel piece of a clog may be made to
expand or contract, I have shewn in the annexed Drawing two modes which may
be employed. The most obvious and simple.one is by means of a screw and nut,
Figure 9, which, being passed through.a heel piece from one side of it to the

page_text: other, may be used to contract its dimensions at pleasure, by screwing up, the nut,
in which case the sides are supposed to expand of themselves, that is, to, say,, to
have an inclination to press outwards, the screw being employed only to contract
them; but I give a decided preference, in practice, to the employment of a spring
and rack, the same as is partly shewn in Figure 1. in perspective, and separately.
delineated in Figures 10, 11, 12., Figure.10 is merely a side view or elevation
of the superadded heel piece, containing the rack spring, and other necessary,
appendages to the same which cannot be here scen.. That part of the clog is
nearly of a semicircular, form, as shewn at Figure. 1, and for the stronger
kind of clogs I prefer making them on the outside of plate iron, or other
metallic. plates, with an inside, lining. of leather, or other elastic compressible,
soft material, which is rivetted to the metallic plate. Figure 11 is a plan of
the under side, and Figure 12 a plan of the upper side of the heel piece..
The letters of reference in Figures 1, 10, 11, and 12, are the same as respects
the same parts; thus, a, a, are the slides and back of the superadded heel
piece, the outside being made of iron and the inside lining of leather. y is a
notched rack, and the spring catch which takes hold of the notches of the
rack. The spring catch, being of hard steel, is fastened by rivets to a short
piece of brass D at one extremity; the other extremity is rivetted or screwed
on the outside, of the iron heel piece, where it is rounded, to give it a finished
appearance: The notched rack y is in like manner rivetted or screwed
on the opposite side. Both the rack and spring bave slot mortices E, E,
inside of each of which is a guiding pin that is fixed into the bottom: plate of
the heel F. At G is. shewn one end of a metallic pin, which is rivetted fast
to the spring, the, other end passing through a slot mortice in the bottom
plate of the heel piece, better seen at G in Figure 12. Supposing the sides
x, x, of the heel piece to be brought close to the bottom plate F, as seen at
Figure 1, then, by pressing with the thumb nail on the pin G, the spring
catch Z, Figure 11) is thrust out of contact with the notched rack, and being
thus relieved of its claw the sides a, a, open or expand in the manner they]
are. represented by Figures 11 and. 12. The sides thus expanded to their
greatest extent are afterwards contracted at pleasure (to suit the wearer of the
clog) by simple pressure from the outside. That portion of the iron heel
marked H is of one piece with the back, and is secured to the bottom
plate by rivets through both, as shewn at H. The four screw holes represented
in the bottom plate are, for screwing down to. the wooden or other heel of
the clog.
Figures 13, 14, 15, are three views of my improved slide for lengthening
or shortening the strap. or. tie of the clog across the instop of the wearer.;

page_text: the same letters in each Figure refer to the same parts in each. It consists
of two plates of iron I, I, laid flatwise in contact with one another, with long
apertures or slots K, K, K, K, in which slide the brass pins L, L, L, L,
Two of these pins are fixed to each plate, and confine the opposite plate by
their heads projecting over it. To give an increased friction to the sliding
plates, and to stop their action, a spring M is fixed to one of the plates, which
spring is mounted at the opposite end with a brass catch N, which, when shut
up, enters the hole O, as shewn at Figure 13.
In witness whereof, I, the said Joseph Schaller, have hereunto set my
hand and seal, the Second day of November, in the year of our Lord
