CERTAIN IMPROVEMENTS IN CLOGS AND PATTENS
Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
ROBARTS, of Tavistock, in the County of Devon, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent, bearing date at Westminster, the Nineteenth day of
June (1850), in the thirteenth year of Her reign, did, for Herself, Her heirs
and successors, give and grant unto me, the said George Robarts, my exors,
adñiors, and assigns, Her especial license, full power, sole privilege and autho-
rity, that I, the said George Robarts, my exors, adiñors, and assigns, and
every of them, by myself or themselves, or by my and their deputy or deputies,
servants or agents, or such others as 1, the said George Robarts, my exors,
adñiors, and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within that part of
Her Majesty's United Kingdom of Great Britain and Ireland called England,
Her Dominion of Wales, and Town of Berwick-upon-Tweed, the Islands of
Jersey, Guernsey, Alderney, Sark, and Man, and also in all Her Majesty's
Colonies and Plantations abroad, my Invention of "CERTAIN IMPROVEMENTS IN
CLOGS AND PATTENS;" in which said Letters Patent is contained a proviso
obliging me, the said George Robarts, to particularly describe and ascertain
the nature of the said Invention, and in what manner the same is to be per-
formed, by an instrument in writing under my hand and seal, and cause the
same to be enrolled in Her Majesty's High Court of Chancery within two
calendar months next and immediately after the date of the said partly-

page_text: recited Letters Patent, as in and by the same, reference being thereto had,
will fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
George Robarts, do hereby declare that the nature of my said Invention, and
in what manner the same is to be performed, are particularly described and
ascertained in and by the present Specification or explanation thereof, refe-
rence being had to the Drawing hereunto annexed and herein referred to in
the words and figures following, that is to say:-
The nature of the said Invention consists in certain improvements in clogs
and pattens whereby such clogs and pattens may be fitted on to or released
from the foot of the wearer without stooping and with much less trouble than
the clogs and pattens constructed or fashioned according to the plans hitherto
adopted. The manner of performing the said Invention is by constructing
the clog or patten, with a back piece to the heel thereof, in such a way that it
may be made to fall back when it is desired to put on the clog or patten, so
as to allow of the insertion of the foot therein, which insertion being effected,
the said back piece of the heel is caused, by mechanical arrangements herein-
after set forth and described, to spring up into its proper position, clipping the
heel of the wearer, and fastening on the clog, the other parts of the clog or
patten being nearly the same as those hitherto adopted; but as regards the
instep straps, they do not require fresh adjustment every time of putting on
the clog or patten, as when they are once adapted to the required size of the
wearer, they may remain so. The clog can be released from the foot by
exorting pressure on the end of a spring protruding beyond the edge of the
clog, which may be effected by the application of the other foot to such pur-
pose; or the clog may be released from the foot of the wearer by simply raising
the heel a little, and drawing the foot from which the clog is to be removed
back against the other foot, so as to cause the latter to touch the end of the
spring protruding beyond the edge of the inside of the clog, which imme-
diately releases the back picce, and it drops down, and the foot can be removed
at once without difficulty. All which will be more clearly ascertained by
referring to the Drawing annexed, and the explanation thereof herein-after set
forth. The aforesaid object of this Invention may likewise be attained by
having a sliding piece connected with a moveable heel, so constructed that
when such sliding piece is pressed forward by the foot, upon the clog being
put on, which being accomplished, the sliding piece will be held to its proper
position by the action of a spring, the pressure of which must be removed
when the clog is to be released from the foot.
The Drawings hereto annexed exhibit at Sheet -1, Fig. 1, side elevation.

shewn by dotted lines. Fig. 3, side elevation of heel, with heel-piece thrown
back, and the lever or click hereafter described in dotted lines. Figs. 4 & 5,
side and back views of heel piece. Fig. 6, bottom view of the iron plate,
shewing the latch and spring hereafter described. Fig. 7, edge view thereof.
Fig. 8, top view of the iron plate shewn combined with the lever or click and
heel piece. Similar letters of reference are placed upon and denote corre-
sponding parts in so far as they can be seen or are made to appear at each of
the Figures respectively.
A represents the sole of the clog; B, the toe cap; C, the heel; D, D, the
instep straps by which the clog is secured by the heel to the foot of the
wearer; E, the back piece to the heel, the same being connected at its lower
end to the extremity of a lever or click F, working upon a pivot G in a slit
formed in the heel of the clog. Across this lever or click at right angles
passes a small thin plate of iron H inserted across the heel or upper part of
the sole of the clog, and covered with the lining leather thereof, and affixed
to this plate of iron underneath is a small bar of iron, which may be termed
the latch K, secured by a staple, and which is acted upon by a spring L. The
end of the latch K protrudes a little beyond the edge of the clog, and is
covered with a piece of gutta percha, as shown at k. This latch K, when in
its usual position, and when the back piece E is also in its proper place,
catches in a notch F*, in the lever or click F', connected with the back piece,
and prevents the back piece from falling down; and when it is wished to
remove the foot from the 'clog, it is simply necessary for the wearer to press
forward a little the end k of the latch (K), as, by drawing the foot back
against the other foot, at the same time raising the foot a little, when the
notchi in the lever or click F, is freed from the pressure of the bar K, which
has thus been pressed forward, and the back piece falls down, and the foot is
removeable without difficulty. In putting on the clog, the back piece of the
heel being of course down, the pressure of the foot on the lever or click F,
which is seen above the surface of the clog (Figure 3, dotted lines), causes it
to press down on the latch K which catches in the notch, and thus the back
piece of the heel springs up close to and clips the heel of the wearer, and
remains thus until the proper measures are taken to release the same. It is
obvious that this mechanical arrangement will suit a clog or pattern mounted
on clog irons or patten irons, as well as clog or patten with a solid leather
heel.
A modification hereafter described of the mechanical arrangements
just described may be used for pattens or clogs, whenever the clog or patten
is mounted on what are termed clog irons or patten irons. In this modifica-

page_text: tion the sole, the heel, and other parts of the patten or clog may remain the
same, as before described, excepting that the patten or clog is mounted on
patten irons or clog irons, and that the mechanical arrangements for actuating
the heel piece differ from the foregoing, inasmuch as the lever or click attached
to the heel piece has a notch formed in the under part instead of the upper
part thereof, and the bar or spring passing across and taking into the same,
consists of one piece only, which is secured underneath the heel of the clog at
one end near to one side thereof in any convenient manner, the other end pro-
jecting a little beyond the other side of the heel being left free, and a knob
similar to (k) provided at this end. The patten irons or clog irons attached to
a patten or clog of this kind should have a portion thereof extending beneath
the said bar or spring to form a rest or stop to prevent its working too far, as
the mode of actuating or using this kind of patten or clog is not to press
forward the said knob, as in the arrangement exhibited by the Drawings at
Sheet 1, but to press down the said knob as at Sheet 2, when the pressure
of the said bar or spring will be taken off the said lever or click, leaving the
back piece of the heel free to be pressed back, as when the foot is pushed into
the patten or clog, when, directly upon the foot being inserted, the pressure
thereof upon the top of the said lever or click will bring the heel piece back
into its, proper position, clipping the heel of the wearer, and thus fastening on
the patten or clog. This kind of bar or spring is also applied as hereafter sot
forth.

patten or clog turned upside down. Fig. 5, side view of the slide showing its
peculiar construction; the said Figures exhibiting a clog or patten having a
moveable heel piece with the same objects as those before described, the
motion being attained by means of a sliding piece instead of by the mechanical
arrangements herein-before set forth. A', the moveable or sliding heel piece.
B, the slide running in a groove from heel to toe. C, the end of the slide
turned up in front, against which the toc presses when the clog is to be put
on, and pushes it forward to the end of the clog. The slide before mentioned
is constructed (as exhibited at Fig. 5) of a long bar or strip of metal or other
suitable material, the under part of which, at the end working in the heel, is
enlarged, having a notch at its under part, across which passes the spring or
bar D', similar to that lastly before described, which has a knob of the same
kind (d) protruding beyond the edge of the clog; and such knob upon being
pressed down removes the spring or bar D from the notch *, and allows the
heel piece to slide back, allowing the foot to fasten on the clog when pressing

page_text: with the toe against the end of the slide (C), thus pressing the heel piece
against the foot. The clog or patten is mounted on clog irons or patten irons
(f), and may be released from the foot by pressing down the knob, and press-
ing back the slide with the heel. The same letters of reference as in Sheet 1
denote parts corresponding with those there exhibited.
Having now described the nature of the said Invention, and in what manner
the same is to be performed, I declare that what I claim as constituting the
Invention for which Her Majesty's Letters Patent were granted to me as
aforesaid, is, the making and constructing of clogs and pattens, with the
improvements aforesaid applied thereto and embodied therein, as herein-before
particularly described and ascertained, it being understood that I do not confine
myself to any particular materials, nor to the precise details of mechanical
arrangements herein-before set forth and exhibited by the Drawings hereunto
annexed, so long as the Invention, the true nature and character whereof, as
herein-before set forth, is adopted, retained, or used. And such my said Inven-
tion being, to the best of my knowledge and belief, new, and never before used
within this realm, therefore I claim to maintain exclusive right and privilego
to the same, according to the true intent and meaning of the aforesaid Letters
Patent.
In witness whereof, I, the said George Robarts, have hereunto set my
hand and seal, this Sixteenth day of August, in the year of our Lord
