Year: 1862

page_text: LETTERS PATENT to Charles Marien Roullier, of Paris, Manufacturer
for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF STRAPS,
BANDS, CHAINS, AND OTHER LIKE ARTICLES."
Sealed the 18th July 1862, and dated the 4th February 1862.
PROVISIONAL SPECIFICATION left by the said Charles Marien Roullier,
at the Office of the Commissioners of Patents, with his Petition, on the.
4th February 1862.
I, CHARLES MARIEN ROULLIER, of Paris, Manufacturer, do hereby declare
the nature of my Invention of "IMPROVEMENTS IN THE MANUFACTURE OF STRAPS,
BANDS, CHAINS, AND OTHER LIKE ARTICLES," to be as follows, that is to say :-
My Invention consists in the employment of waste new or old leather alone,
or of such leather and metal combined for the manufacture of straps, bands,
chains, and other like articles, and in the mode of manufacturing the same..
To form driving straps for machinery and other straps and bands, I employ
waste pieces obtained from waste or old or new leather cut into an oblong
form with the four angles cut off to form links; the metal links employeḍ
therewith are rather shorter than the leather links and unite with the latter.
The links are joined together by metal pins adjusted in holes made in the
links, so as to form joints. The pins for uniting the links together are
rivetted to their extremities outside the band or strap, or they may be made

page_text: with a screw thread, and fastened by means of a screw nut on one or both
sides. The pieces of strap thus formed of the desired length may afterwards
be united to form the full length of the strap by means of keys, bolts, and nuts.
The bands may be lengthened or shortened by adding on or removing one or
more rows of links. To construct a chain or strap capable of supporting a
great strain, or of being employed as a suspension chain, or for supporting a
weight, I unite alternately a link of leather of the required form with a link.
of metal, and form a width of rows of such combined links proportionate to the
strength of the band or chain required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Marien Roullier in the Great Seal Patent Office
on the 23rd July 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
MARIEN ROULLIER, of Paris, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of February, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Charles Marien Roullier, Her special licence that I, the said Charles
Marien Roullier, my executors, administrators, and assigns, or such others
as I, the said Charles Marien Roullier, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF STRAPS, BANDS, CHAINS, AND OTHER LIKE
ARTICLES," upon the condition (amongst others) that I, the said Charles
Marien Roullier, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain. the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Marien Roullier, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and. by the

page_text: sufficent number to form the breadth of the band, and the pins are passed
through the holes in their extremities. The axes of the links are rivetted at
their two extremities, and are furnished with washers c, as shown at Figure-10,
applied on the links forming the two lateral faces of the band, and by which
the links forming the breadth of the band are held together firmly in their
places. Instead of washers, I can employ a metallic plate, as shewn at c¹,
Figure 8, in the form of a link, with holes for the passage of two pins b, b.
The bands or straps may be made in several parts, and afterwards united to
form one length by pins and rivets or screws and nuts. The jointed band's
thus made may be lengthened or shortened by adding or removing one or
several rows of links. To prevent or lessen the elongation of the bands when
in use, I introduce into the width of a band composed of tanned leather links,
rows of links, made of dried untanned pieces of leather or bullocks sinews.
If bands are required to be used as suspension chains or flat cables, or for
'supporting a great strain or weight, links of metal are interposed between the
leather links to give greater strength to the band. The same result may be
obtained by applying to the two faces of each leather link thin plates of zinc,
iron, copper, or other like resisting metal. When the bands are to. be
employed as flat cables for mines and collieries, I make use of wooden links,
as shewn at Figures 11 and 12, enclosed between the leather links, or arranged
in the most suitable manner. Around these links a groove e is made, in which
is placed and wound round a metallic wire f, as shewn at Figure 10, for giving
strength to the links and preventing them from bursting or elongating. The
exterior surfaces of the links are furnished with metallic plates d, the plates
which come in contact being of different metals to diminish the friction: The
pins or axes g, Figure 13, of the several links are of iron, and covered with a
tube or envelope of india-rubber or gutta percha to give softness and elasticity
to the joints. To obviate the injurious effects of humidity, the wooden links
are covered with a solution of india-rubber or gutta percha: In place of
metal or wooden links, I can employ and place between the leather links links
of cane, horn, indurated india-rubber, or other like material, according to the
strength required. I also combine with the leather links links composed of
'sheets of veneer applied one against the other, with the grain crossed. These
sheets of veneer are furnished on each exterior face with cloth; cardboard, or
felt coated with india-rubber, the whole being covered externally with thin
leather. The various materials before mentioned may be combined. in any
number and order to form auxiliary links, and be introduced between the
leather links. I would observe that the employment of links of the various
materials enumerated should only be considered as an additional means of

page_text: forming the bands, and that the leather links constitute the principal and
essential part of my Invention. I would further observe that the main feature
of this new kind of strap is, that the links are moveable on the pins, 'so that all
parts of the strap can turn freely thereon as on an axis.
Having now described the nature of my said Invention, and the manner of
carrying the same into effect, I wish it to be understood that I do not confine
myself to the precise details of construction or of materials herein-before
described and enumerated, and that I reserve to myself the right of modifying
my mode of construction, and employing other suitable materials in combination
with pieces of waste leather; but what I consider as my Invention, and
intended to be secured by the said herein in part recited Letters Patent, is,―
First, the employment of waste leather for the manufacture of driving straps
or bands, chains, and other like articles for the transmission of motion or
power, as herein-before described, and represented in the accompanying
Drawing.
Secondly, the mode of manufacturing jointed or articulated straps and bands,
and other like articles, with links consisting of pieces of waste leather, alone
or combined with links of metal or other material, as herein-before described
and shewn by the annexed Drawing.
In witness whereof, I, the said Charles Marien Roullier, have hereto
set my hand and seal, this Twelfth day of July, One thousand eight
hundred and sixty-two.
ROULLIER. (L.S.)
