WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lako, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN THE MANUFACTURE OF
ENDLESS BANDS OR STRAPS." [A communication from abroad by Charles Marien
Roullier, of Paris, France.]
This Invention relates to endless bands, straps, or belts which are manufactured
of cuttings or waste pieces of hides, skins, leather, and the like pasted or glued
together and arranged in several layers superposed in such a manner as to form
leather bands, belts, or straps, which are then covered on both faces with strips of
strong linen cloth glued and sewn or rivetted to these two faces.
In carrying the said Invention into practice I proceed as follows, that is to
say :-
Pieces of hide, leather, or similar material, the edges of which have been thinned,
are put into a tub or vat containing very strong paste or glue, from which they are
afterwards withdrawn and so placed upon a band or strip of linen cloth that their
edges overlap each other and form a continuous layer. These pieces are then
covered with a second band or strip of linen cloth, and the whole is subjected to
pressure under pressing rollers, which form the first thickness of continuous leather.
The upper strip of linen is then removed and a second layer of pieces of leather
or the like is deposited from the tub or vat; then the linen strip is added, pressure
is again applied, and a new band of continuous leather is obtained thicker than the
first. These operations are continued until the band or strap is of the desired
thickness and strength, then it is trimmed to the required width, and the two faces
are scraped. I coat these two faces with paste or glue and apply upon each a band
or strip of linen cloth made for the purpose according to the width of the belt or
strap. I sew the whole together with several rows of sewing in order to well secure
[Price 6d

page_text: all the parts of the belt or band, or two or more lines of rivets may be employed for
this purpose. This having been effected the band or belt is finished.
In some cases I may have strips or bands of linen between the different con-
tinuous layers of leather, and it will be understood that in all cases there will be
such bands or strips of linen on the exterior faces of the belt.
I may use for the manufacture of the said improved belts or straps sheets of
pasted or glued and compressed leather, known as artificial leather. In this case
these sheets are trimmed to the width which it is desired to give to the belt or
strap to be made, and the ends of such sheets are thinned to facilitate their being
pasted together continuously in such a manner as to form the continuous band, belt,
or strap; then they are covered with strips or bands of linen cloth as above
explained. These sheets of artificial leather may be made by the process herein-
before explained for the manufacture of the said improved belts or straps. The
only difference in the two methods abovo described is that in the latter the sheets
of artificial leather are ready prepared when I commence to make the endless band
or belt, and in the former they are not.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN THE MANUFACTURE OF
ENDLESS BANDS OR STRAPS." A communication from abroad by Charles Marien
Roullier, of Paris, France.
This Invention relates to endless bands, straps, or belts which are manufactured
of cuttings or waste pieces of hides, skins, or leather, and the like pasted or glued
together, and arranged in several layers superposed in such a manner as to form
leather bands, belts, or straps, which are covered on both faces with strips of strong
cloth glued and sewn or rivetted to these two faces.
In carrying the said Invention into practice I proceed as follows, that is to
say:
Pieces of hide, leather, or similar material, the edges of which have been thinned,
are put into a tub or vat containing very strong paste or glue, from which they are
afterwards withdrawn; they are then so placed upon a band or strip of woollen or
other cloth that their edges overlap each other and form a continuous leather surface
or layer. These pieces are then covered with a second band or strip of cloth, and
the whole is subjected to pressure under pressing rollers, thus forming the first
thickness of continuous leather. The upper strip is then removed and a second
layer of pieces of leather or the like taken from the aforesaid tub or vat is deposited
on the first band; then the cloth is added, pressure is again applied, and a new
band of continuous leather is obtained thicker than the first. These operations are
continued until the band or strap is of the desired thickness and strength, then it
is trimmed to the desired width, and the two faces are scraped; these two faces are
coated with paste or glue, and I apply upon each a band or strip of strong cloth
made for the purpose according to the width of the belt or strap. The whole is
securely sewn together with several seams, in order to well secure all the parts of
the belt or band; or two or more lines of rivets may be employed for this purpose.
The band or belt is then finished.
In the accompanying Drawing I have illustrated my Invention in different views,
shewing the bands in course of manufacture and finished.
Figure 1 shews in longitudinal section the two bands a, a, of woollen cloth
between which the pieces of hide b are placed before subjecting them to the first
pressure.
Figure 2 shews in plan the arrangement of the pieces of hide 6 upon the lower
cloth a
These pieces coated with glue or paste are united by pressure and con-
stitute the first band of continuous leather, upon which is placed the fresh pieces of
hide to unite them in the same manner and form another band, which will be glued
or cemented upon the first one.
In some cases I may have strips or bands e of cloth between the different con-
tinuous bands of leather, and it will be understood that in all cases the latter will
be covered by bands or strips of cloth d.
Figure 3 is a longitudinal section of a strap or belt made according to this modi-
fication of the said Invention, with an intermediate band of cloth.
Figure 4 is a plan of the same, shewing how the bands of cloth and leather which
constitute the improved belt or strap may be sewn or rivetted.
Figure 5 is a longitudinal section of a strap or belt, and made as shewn in Figures
3 and 4 with an intermediate band of cloth.
I may use for the manufacture of the said improved belts or straps sheets of
pasted or glued and compressed leather, known as artificial leather. In this case
these sheets are trimmed to the width which it is desired to give to the belt or
strap to be made, and the ends of such sheets are thinned to facilitate their being

page_text: pasted together continuously in such a manner as to form the continuous band, belt,
or strap; then they are covered with strips or bands of cloth as above explained.
These sheets of the so called artificial leather may be made by the process herein-
before explained for the manufacture of the said improved belts or straps. And in
this case the latter and those first above described will differ from each other only
in the fact that in the one case the artificial leather is, and in the other case is not,
prepared beforehand.
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 manufacture of endless bands or belts with one or more continuous bands or
strips formed of pieces of hide or leather glued and compressed, or artificial leather
prepared or not prepared beforehand, superimposed and glued together with or
without intermediate bands of cloth, and covered with two bands of strong cloth
sewn or riveted by two or more seams or rows, all substantially as and for the
purpose specified.
In witness whereof, I, the said William Robert Lake, have hereunto set
my hand and seal, this Twenty-ninth day of October, in the year of our
Lord One thousand eight hundred and seventy nine.
