FACTURE OF BOOTS AND SHOES WITH METALLIC CAMBERING."
PROVISIONAL SPECIFICATION left by the said Gabriel Champomier at the
Office of the Commissioners of Patents on the 25th April 1878.

GABRIEL CHAMPOMIER, Boot Maker, of the City of Paris, in the Republic of
France. "IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND SHOES WITH
METALLIC CAMBERING."
The feature of novelty in this Invention consists in the adaptation to boots and"
shoes of metallic cambering which is applied to the hollow of the boot or shoe, the
object being to preserve the arch, add strength to the articles, obviate sewing, and
render those thus provided healthy to wear, the part of the boot or shoe to which
it is applied being rendered impervious to wet, whilst at the same time a graceful
form is insured and maintained.
The cambering referred to consists of a metal plate which is previously cut of the
size required, according to the No. of the boot or shoe; it is then stamped, to give it
the required arch, and is made either of a length to extend to the inside of the heel,
or it may be made to pass over it and form one continuous piece; it is attached to
the boot or shoe either by screws, rivets, or some equivalent.
The sole may be divided in two, so that when one part has been screwed the
other may be covered by it.

"
GABRIEL CHAMPOMIER, Boot Maker, of the City of Paris, in the Republic of
France.
IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND SHOES WITH
METALLIC CAMBERING."
The feature of novelty in this Invention is the application of metallic cambering
to boots and shoes for men, women, and children, that is to say, to boots and shoes
of all kinds. This metallic cambering may be prolonged at will, so as to form
a base beneath the heel or follow the form or hollow of the foot for boots of
Louis XV. design.
The cambering is fixed in several ways to the boot or shoe, either by screw pins,
and rivets, or sewn thereto. It is cut and then stamped to give it the requisite form,
according to the number of the boot or shoe to which it is to be applied. The cam-
bering is then provided with small pointed shafts intended to fix it to the boot or
shoe.
It should be observed that this new arrangement replaces sewing advantageously,
at the same time that it is healthy.
Moreover, in addition to the solidity of the boot, it imparts to it a certain elegance,
the combination therewith of a cambering so narrow that I give it the name of the
filiform cambering.
I reserve to myself the privilege of fastening this metal cambering by any suitable
or known method, and to employ it for all kinds of foot covering, and to dispose the
first in such wise as to divide it in two parts, so that after one has been rivetted it
may be covered by the other.
I claim also the right to make the cambering in any metal, coated, if desired, by
galvanic process, say for example, with steel, nickel, and so forth.
The forms shown in the Drawings are only general, but which can be varied as
may be deemed necessary.
The advantages of this cambering which are here enumerated will clearly illus-
trate the nature of the Invention, basing my claim not merely on the form of the
cambering, which, as already stated, may be variable, nor restricting myself to any
special metal; these advantages may be thus stated,―
1st. By uniting the heel with the sole by a metallic cambering, the heel cannot
be separated from the sole which consolidates it.
2nd. This admits of using a wooden heel, or otherwise, for an elegant boot or
shoe, by narrowing the arch or cambering, and applying it to the sole or not, as
required.
3rd. The cambering is of various dimensions; it is larger for army shoes or boots
and hunting boots.
4th. It may be open in the centre, leaving the edges only, so that the sole leather
reaches to the heel.
I may also place a hinge near the middle of the cambering, and another adhering
to the sole.
It may also be varnished to give it the requisite colour, and instead of cutting
and stamping them they may be cast in iron by any known process.
When the cambering extends to the heel it may be ornamented by any
design, whether it encases, the heel, or reaching from beneath the heel it extends
upwards in a plate.
Fig. 1 shows a boot supplied with my metal cambering a.
Fig. 2 shows the cambering alone.
Fig. 3 represents the cambering a as lengthened to pass under the heel b.
Fig. 4 is the cambering applied to a boot or shoe of the Louis XV. pattern.
Fig. 5 represents a soldier's boot or shoe, the cambering extending under the heel,
and rises in front, facing the sole. The heel is supplied with a hoop or prongs for

page_text: fixing on the heel or to allow of changing it; this naturally applies to all boots
and shoes.
Fig. 6 is a side view of the heel; a is the cambering; c, the prong; d, orna-
mentation at the side.
Fig. 7 is a front view or face of the heel, ornamented, if desired; c, prongs; a,
cambering.
Fig. 8 is a plan of the heel with prong c, and cambering a.
Fig. 9 shows a spur applied to the cambering; in this Drawing it will be seen
that the spur is without branches; the part e, f, passes through the heel; the spur
box is also simplified; it consists merely of a shaft and spring below.
Fig. 10 shows the application of the spur to a boot, where, instead of å shaft e, f,
all the part e, f, g, h, is solid.
It has been mentioned that the heel can be changed by claws, springs, or hooks,
or some equivalent may be used that will facilitate changing the heels; these attach-
ments may be applied to the base, and the good end be changed when required.
Fig. 11 represents the cambering plate, which is either solid or hollow, as here
shown.
In witness whereof, I, the said Gabriel Champomier, have hereunto set my
hand and seal, this Twenty-fourth day of October, in the year of our Lord
One thousand eight hundred and seventy-eight.
