the Commissioners of Patents, with his Petition, on the 19th January
1859. A communication from Charles Jules Pierre Desnos, of 29,
Boulevard St. Martin, Paris, in the Empire of France.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer & Patent Agent, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN BOOTS & SHOES, AND IN THE MACHINERY,
APPARATUS, AND MEANS EMPLOYED IN SUCH MANUFACTURE," to be as follows:
First, this Invention consists of and relates to novel and improved means
for imparting motion to a boots or shoes while the sole and heel are being
attached thereto or otherwise operated upon, and which motion can be com-
municated to the frame containing the shoe, &c., and parts connected therewith
to the parts for driving, perforating, or inserting the fastenings; & it consists
in the application of a screw, change wheels, and templates to such motion;
and it also consists in the application of a template somewhat similar in
outline to the boot or shoe sole, & which is made to guide through a
connecting shaft or lever, the boot or shoe, or the inserting or piercing
parts, motion being imparted to the said connecting lever, rod or shaft, by
means of a screw & cam, or either, provision being made for changing the
centre of action, cam, or wheels, so as to obtain various sizes from one
model.
Secondly, it consists of an improved mode of fastening the heel and part of
the sole of a boot or shoe, and in the means or apparatus employed for that

page_text: purpose, and which operation is performed from the inside of the boot, and
consists of the use and application of one or more piercers or drivers and
guides for the same, in which they are free to move, and which may be made
to perforate and insert the fastening either by pressure or concussion, opera-
ting either upon the piercers separately or combined; and it also consists of
the use and application of guides or cells for the fastenings to be employed,
whether made of metal or otherwise.
Thirdly, this Invention consists in counter-sinking the soles or other parts
of boots & shoes, and also in perforating the various parts in combination with
such counter-sinking, & which may be performed by suitable punches and
inserted in plates or dies.
Fourthly, it consists in the employment of novel & improved tack or rivet
fastenings for boots or shoes, and their use in combination with such
countersunk holes; they may be employed for uniting the sole and the heel to
the other parts, or employed for fastening on additional soles, and in addition
to all ordinary fastenings which may be applied to the aforesaid counter-
sinking, I employ nails, tacks, or rivets of a round taper form, or with chisel
points, and also said tacks, nails, or rivets with thick heads, said heads being
of greater or less depth; and in other forms I use tacks, nails, or rivets
compressed in suitable parts of greater or less circumference; and in other
cases besides the head I press a flange upon such nails, tacks, or rivets, either
in the centre or in any other part. This latter being more particularly
applicable to gutta percha soles when the gutta percha is heated.
Fifthly, it relates to a novel and improved mode of lasting or mounting, and
which consists of a sliding or separate action or motion being imparted to a
support and presser for forcing the upper upon the last or stand, and the use
and employment of such moveable part in connection with such stand or last,.
and the covering or combining of such part with india-rubber.
