HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co Patent Agents,
Southampton Buildings, London, "AN IMPROVED CRIMPING MACHINE FOR USE
IN THE MANUFACTURE OF BOOTS, SHOES, AND SIMILAR ARTICLES [A communi-
cation from abroad by Gustave Pierre Ernest Lenormand-Carpentier, of Amiens,
France, Manufacturer,]
This Invention relates to crimping machines for use in the manufacture of boots,
shoes, and similar articles.
The crimping machines hitherto employed are restricted in their production.
My improved machine will crimp as desired, the backs or the fronts of boot-uppers
and its production is considerably more than that of the machines hitherto employed
when being turned by hand; and this production would be greatly increased if a
motor apparatus were employed.
My machine also allows of crimping the leather for the fronts and backs of boots
which are crimped in two pieces, boots crimped in a single piece, and seamless
lace-up boots, without any change being made in the machine. It consists
essentially of two vertical plates each provided with a jaw at its upper end and
between which rotates a crimper which has four or more branches.
The same apparatus will crimp the upper of a walking-boot or a house-boot; it
is only necessary to place the leather more or less between the two jaws;-by
turning in one direction the back of the boot is crimped and by turning in the

page_text: opposite direction the front of the boot is crimped. The two plates may have any
position in the machine, being placed either between the frames, or at the sides, as
the case may be, one on each side of the machine. The desired adjustment is
obtained by means of set-screws. The crimper may be fixed directly upon the
rotary shaft, or it may be fixed to a gear-wheel which turns between two jaws and
receives motion by means of a pinion, placed at one end of the machine and fixed
upon a shaft which carries at its end a toothed-wheel; this toothed-wheel gears
with another pinion upon a shaft provided with a crank-handle or other means for
imparting motion to the said machine.
The crimper is formed of a plate cut out of a single piece of sheet metal or it
may be formed of as many pieces as there are crimping arms; these arms being
suitably cut out and fixed to the plate at the middle and to an exterior disc or
other contrivance by means of screws, bolts, or rivets.

HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings, London, "AN IMPROVED CRIMPING-MACHINE FOR USE
IN THE MANUFACTURE OF BOOTS, SHOES, AND SIMILAR ARTICLES" A. communi-
cation from abroad by Gustave Pierre Ernest Lenormand-Carpentier, of Amiens,
France, Manufacturer,
This invention relates to an improved crimping machine for use in the manu-
facture of boots, shoes, and similar articles.
The crimping machines hitherto employed are restricted in their production, but
according to the present invention I provide a rotary machine suitable for the
manufacture of uppers for all descriptions of boots and shoes. My improved
machine will crimp, the backs or the fronts of boot uppers; its production, when
operated by hand, is considerably more than that of the machines hitherto
employed; and this production would be greatly increased if a motor were
employed.
My said machine also allows of crimping the leather for the fronts and backs
of boots which are crimped in two pieces, boots crimped in a single piece, and
seamless lace-up boots, without any change being made in the machine.
In the accompanying drawing,
Figure 1 is a sectional elevation of a circular crimping machine made according
to the said invention.
Figure 2 is a vertical central section thereof.
Figure 3 is a horizontal section of the same on the line M, N, Figure 1, and,
Figures 4 and 5 represent two views of a boot upper.
A, A¹, are two vertical plates provided with jaws at their extremities; between
these plates a crimper C (which is represented in the drawing as having four blades
or branches) is adapted to be rotated. The number of blades of the crimper may
be varied if desired.
The same apparatus will crimp the upper of a walking-boot or a house-boot; it
is only necessary to place the leather more or less between the two jaws; by
turning in one direction the back of the boot is crimped and by turning in the
opposite direction the front of the boot is crimped. The two plates A, A¹, may
occupy any suitable position in the machine, they are shown in the drawing placed
between the frames; the adjustment for giving the desired pressure is effected by
means of the set screws V. The crimper may be fixed directly to the rotary shaft
or to a hub thereon; it is shown in the drawing fixed to the rim or periphery of
the gear-wheel H which is fastened between two jaws I, I, and receives motion by
means of the pinion K placed at one end of the machine and fixed upon the shaft Ŏ
which carries at its end the toothed-wheel L; this toothed wheel gears with the
pinion N upon a shaft which is provided with a crank-handle M or other means
for imparting motion to the said machine.
In Figures 4 and 5 are represented the upper of a boot before and after it has
been crimped by the said machine.
In the machine shown in the drawing the crimper is formed of a plate cut out
of a single piece of sheet-metal; but it may be formed of as many pieces as there
are crimping arms or blades, these arms being suitably shaped and fixed to a hub
at the centre and to the toothed rim or periphery of the wheel H, by screws, bolts
or rivets.

page_text: It will be obvious that the form and dimensions of the various parts, as well as
the arrangement and construction, of the said machine, may be modified in many
ways without departing from the nature of the said invention.
Having thus fully described the said invention as communicated to me by my
foreign Correspondent, and the manner of performing the same, I wish it understood
that I claim,
The improved rotary crimping machine having arms or blades, more or less in
number, cut out of a single piece of sheet-metal or formed of separate pieces fixed
to a hub or shaft in the centre and to the rim or periphenry of the toothed wheel,
and turning between two adjustable plates to crimp the fronts or the backs of
boot uppers and similar articles, substantially as above set forth.
In witness whereof I the said Henry Harris Lake have hereunto set my.
hand and seal this Twenty second day of September in the year of our
Lord One thousand eight hundred and eighty two.
