Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
MASON, of Northampton, Merchant, 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-seventh day of January, in the fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Samuel Mason, Her especial licence, full power, sole privilege and authority,
that I, the said Samuel Mason, my exors, adñiors, and assigns, or such others
as I, the said Samuel Mason, my exors, admors, or assigns, 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, exer-
cise, and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "IMPROVEMENTS IN CLOGS, PART OF WHICH IMPROVEMENTS IS ALSO
APPLICABLE TO BOOTS AND SHOES;" in which said Letters Patent is contained a
proviso, that I, the said Samuel Mason, 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 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
had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Mason, do hereby declare that the nature of my Invention, and the
manner in which the same is to be performed, are fully described and ascer-

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a clog constructed according to the first part of my
Invention; Figure 2 shows the same construction of clog on a foot. Theso
clogs are made of india-rubber in the ordinary manner, but in place of having
them lined throughout, as heretofore, only the heel and toe parts are lined,
leaving the spaco indicated by dotted lines a, a, to net by its elasticity to draw
it into the position shown in Figure 1 when off the foot; and when on the
foot, the elasticity, which has a tendency to draw the toe part towards the
heel, will retain the clog securely on the foot; or in place of having no
lining at the parts a, a, there may be a lining, the fabric being placed
with the warp diagonally or otherwise, to allow of the stretching of the india-
rubber, and at the same time the elastictity thereof will only be restrained.
I will now describe the second part of my Invention. Figure 3 shows
a plan, Figure 4 a side view in section, and Figure 5 a side view, of a
elog constructed according to the second part of iny Invention, and consists
of a modo of applying nu elastic spring sole to connect the toe and heel
together, and in such manner that by bending the plate into an arc, so that
when the clog is off the foot the spring sole will cause the toe part to
approach the heel of the clog, as is indicated at Figure 4; the ellect of which
arrangement will be, that when the clog is on the foot the spring sole will be
straightened into the figure shewn at Figure 5, and, owing to the tendency
which the spring sole has to bend into the figure shown at Figure 4, the clog
when on the foot will be held secure thercon and not require fastening. The
heel trend and the toe tread in Figures 3, 4, and 5 are of leather, but this may
he varied so long as the spring sole is bent in the direction shewn in Figure 4,
and to an extent to securely hold the clog on the foot when placed thereon.
And have in Figures 6, 7, and 8 shown a clog with treads of wood
connected together by a steel spring sole, which causes the heel and toe
parts to stand at two ends of a curve, which requires to be straightened in
putting on the clog, the spring solo when so straightened having tendency
again to bend keeps the clog securely on the foot.
I would remark that I am aware that spring soles have before been applied
to clogs, I do not therefore claim the same when not so applied as to cause
the heel and toe parts to approach each other in the manner shewn and
described.

page_text: I will now describe the third part of my Invention, which varies from
that last described only inasmuch as there is no tread applied at the heel,
but in place thereof there is a frame or band to fit the heel of the boot or
shoe to which the clog may be applied, but the bending of the spring sole
is similar to that above described, and is in this case, as before, the means
of keeping on the clog when applied to the foot. Figure 9 shows a plan,
Figure 10 a side view, in section, Figure 11 a side view. of a clog, according
to this part of my Invention.
I will now describe the fourth part of my Invention, which is somewhat
similar to that last described; but in place of the clog being kept fast on the
foot by the using of a bent steel spring sole, the sole in this part of my Inven-
tion though of metal, does not act by its elasticity to keep on the clog; but in
place thereof I apply the screw b, as shown at Figures 12 and 13, passing
through the frame c, c, so that when the clog is placed on the foot, and the
screw turned so as to enter the heel of the boot or shoe, the clog will be
securely retained by the screw b. In this clog there is no tread to the heel,
but the frame c is intended to fit the heel of the boot or shoo to which the
clog may be applied; or it may be desirable in some cases to make the frame
c, c, of elastic metal, and to allow one side of the frame c, c, to move in a
socket at c', by which the frame will be capable of being adjusted to the size
of heel, and by its elasticity will retain the clog on the foot; but I prefer the
mode heretofore described of fastening by means of the screw b. Figure 12
shows a plan of a clog constructed according to the fourth part of my Inven-
tion, and Figure 18 shows the same construction as applied to the foot.
Invention ;
I will now describe the fifth part of my Invention. This part of my
Invention is similar in its mode of fastening clogs to that just described,
but in this case the clogs have treads applied at the heels. Figure 14
shows a side view of a clog according to this part of my
Figure 15 shows a plan thereof; Figure 16 shows the clog applied to
the foot, the heel part being shown in section; on to the heel is applied the
plate d, d, and through the upright c is applied the screw b, which enters
into the heel of the boot or shoe to which the clog may be applied.
I will now describe the sixth part of my Invention, which also relates to a
mode of fastening clogs to the feet, and consists in using a spring catch.
Figure 17 shows a side view of a clog; Figure 18 shows another side view,
partly in section. Figure 19 shows a plan of a clog constructed according
to this part of my Invention; and Figure 20 shows the details of the spring
catch, and the stop applied to the heel of a boot or shoe. e is the spring
catch, which moves on an axis; f and 9 is a spring, which has a tendency

page_text: to keep the catch to the position shown; h is the stop, which is applied to
the heel of a boot or shoe; by which arrangement, when the foot is introduced
into the clog, the spring catch e will give way when it is pressed against by
the under side of the stop h, and when the stop has passed the hooked end of
the catch the spring will cause the hooked end of the spring catch e to hold
the stop, and thus will the clog be securely held on the foot.
I will now describe the seventh part of my Invention, which relates to a
mode of applying soles to clogs and to boots and shoes by means of india-
rubber cement. In manufacturing boots, shoes, or clogs according to this
part of my Invention, I use india-rubber cement in the following manner :-I
prepare both out and in-sole on the flesh side by taking off all superfluous flesh,
then ruft in a dry state with a grindstone or ruff instrument, such as a rasp,
to raise the fibre of the leather, and in this state 1 apply coats of solution of
india-rubber until it is sufficiently thick; when the in-sole is dry I consider it
prepared and fit to be put on the last, I then adopt the usual mode of sewing the
upper to the in-sole; when the same is sewu I apply a coat of solution all over,
and especially to the edges of the upper stuff or leather, 1 then warm the
inside of the out-sole which is already coated with india-rubber cement, and
apply it to the in-sole and "upper" leather or other material, securing it
thereto by pressure till dry; when dry it is taken off and finished in the usual
way. Sometimes I apply a welt of leather or other material coated over with
india-rubber cement, such welt being sown round the in-sole; the shoe is then
inade as above-described, and the welt is applied to the out-sole (coated with
india-rubber) by means of pressure. Or, I sometimes prepare the sole in
the manner already described, taking care that there is a thick coat of india-
rubber) upon the sole to which I am about to attach the upper leather or
other material without sewing, which is lasted over tho in-sole or out-sole, as
occasion may require, for a pump or double sole. I have the coat of india-
rubber in that state which may be called dry, and which by warm pressure has
the strongest adhesion; I have the edges of the upper leather or other
material coated with india-rubber, and if of leather the edges are roughed.
The filling between the soles, where a welt is used, I prefer to be of fibrous
materials saturated with india-rubber, but other materials may be used. I
would remark that I am aware that clogs made of india-rubber for the upper
parts have had leather soles applied thereto by cementing with india-rubber
cement, and I would state that this part of my Invention is confined to the
applying soles to boots, shoes, or clogs having the upper parts made of leather
or of woven or felted fabrics.
Ilaving thus described the nature of my Invention, and the manner in

page_text: which the same is to be performed, I would have it understood that what I
claim is,
First, the mode of constructing india-rubber clogs as described in Figures
1 and 2, whereby the india-rubber, by the bend of the sole and the elasticity
of the sides (as indicated by dotted lines a, a), will retain the clogs on the
foot, as described.
Secondly, I claim the mode of constructing clogs by applying a bent spring.
sole, and in such manner as to cause the toe and heel to approach each other
when taken off the foot, as above described in respect to Figures 3, 4, 5, 6, 7,
and 8.
Thirdly, I claim the mode of applying a bent spring sole without a tread
for the heel, as described in respect to Figures 9, 10, and 11, the bent spring
sole keeping on the clog.
Fourthly, I claim the mode of fastening clogs made without a tread for the
heel, by means of frames for the heels, with screws or other catches, as
described in respect to Figures 12 and 13.
Fifthly, I claim the mode of fastening clogs by applying a screw b, as
described in respect to Figures 14, 15, and 16.
Sixthly, I claim the mode of fastening clogs by means of a spring catch, as
described in respect to Figures 17, 18, 19, and 20.
And, seventhly, I claim the mode of making boots, shoes, and clogs by
applying soles by means of india-rubber cement.
In witness whereof, I the said Samuel Mason, have hereunto set my hand
and seal, this Twenty-seventh day of July, One thousand eight hundred
