IMPROVEMENTS IN THE TREATMENT OF VULCANIZED FIBRE FOR PRODUCING APPARATUS OR ARTICLES USED IN THE MANUFACTURE OF TEXTILE FABRICS."
Year: 1880

page_text: LETTERS PATENT to Julius Ceasar Leigh, of Moorside St., Droylesden, in the
County of Lancaster, Warper, for an Invention of "IMPROVEMENTS IN THE
TREATMENT OF VULCANIZED FIBRE FOR PRODUCING APPARATUS OR ARTICLES
USED IN THE MANUFACTURE OF TEXTILE FABRICS."
PROVISIONAL SPECIFICATION left by the said Julius Ceasar Leigh at the
Office of the Commissioners of Patents on the 16th October 1880.

"IMPROVEMENTS IN THE TREATMENT OF VULCANIZED FIBRE FOR
PRODUCING APPARATUS OR ARTICLES USED IN THE MANUFACTURE OF TEXTILE
FABRICS."
Hitherto shuttles, bobbins, picking sticks, and loom beams employed in spinning
and weaving have usually been constructed of various kinds of wood, and are
consequently liable to breakage, splintering, and other defects, and to wear rapidly,
and in some cases with rough and frayed edges and surfaces, thus increasing the
amount of friction and waste.
The object of my Invention is to produce shuttles, bobbins, picking sticks, and
loom beams which shall be free from the defects alluded to, and to this end my
Invention consists in constructing them of vulcanized fibre, which is a tough and
homogeneous substance free from the defects before mentioned, and which I have
discovered wears longer and with less friction than wood of any of the descriptions
ordinarily employed.
To carry my Invention into effect I cut, press, bend, or otherwise shape the
vulcanized fibre into the requisite forms. When the article cannot conveniently be
cut or otherwise shaped, and has to be moulded into the requisite form, I take the
unvulcanized fibre, press it into suitable moulds, and submit it to the action of heat
in the process known as vulcanization. When it is desired to join two or more
pieces together I partially dissolve the surfaces to be joined with the mother liquor
of chloride of zinc or other solvent, and press them together under the influence of
heat until a union is effected, or the pieces may be joined by means of marine glue
or other cementitious substance. When it is necessary to employ other materials
in conjunction with the fibre, I secure them thereto in a similar manner to that
adopted when the articles are constructed of wood, with the addition when
requisite of the cementing process already described.

JULIUS CEASAR Leigh, of Moorside Street, Droylesden, near Manchester, in the
County of Lancaster. "IMPROVEMENTS IN THE TREATMENT OF VULCANIZED FIBRE
FOR PRODUCING APPARATUS OR ARTICLES USED IN THE MANufacture of Textile
FABRICS."
Hitherto shuttles, bobbins, picking sticks, and loom beams used in spinning and
weaving have usually been constructed of various kinds of wood, and are con-
sequently liable to breakage, splintering, and other defects, and to wear rapidly,
and in some cases with rough and frayed edges and surfaces, thus increasing the
amount of friction and waste.
The object of my Invention is to produce shuttles, bobbins, picking sticks, and
loom beams which shall be free from the objections alluded to, and to this end my
Invention consists in constructing them of vulcanized fibre, which is a tough and
homogeneous substance free from the defects before mentioned, and which I have
discovered wears longer and with less friction than wood of any of the descriptions
ordinarily employed. To carry my Invention into effect I take the vulcanized
fibre in the form of thick sheets in which it is usually supplied, and cut it by
means of saws, chisels, and cutters into the desired shape. In some cases the
material may require to be bent, which may be done with or without the aid of
heat and pressure, but I prefer to employ both of these aids. In other cases the
articles may be pressed into shape, or the three processes of cutting, bending, and
pressing may be combined to secure the requisite forms. When the article cannot
conveniently be produced by the methods described, and it is desired to mould it
into some particular form, I take the fibre in the form of pulp prior to vulcanization,
press it into suitable moulds, and submit it to the action of heat in the process
known as vulcanization. In some instances it is desirable to employ other
materials in conjunction with the vulcanized fibre, in which cases I secure them
thereto in a manner similar to that which would be adopted in securing them to
wood in conjunction when necessary with the cementing process hereinafter
described. In order to join two or more pieces of the vulcanized fibre together
I clean the surfaces and apply the mother liquor of chloride of zinc or of other
metallic chlorides or other solvent, and then press them together under the
influence of heat until a union is effected, or the pieces may be joined by means of
marine glue or other cementitious substance.
Having thus described the nature of my said Invention, and the best manner
known to me of carrying the same into effect, I would have it understood that
I claim,―
The construction of the shuttles, bobbins, picking sticks, and loom beams used in
the manufacture of textile fabrics from the material known as vulcanized fibre,
substantially as herein described and indicated.
In witness whereof, I, the said Julius Ceasar Leigh, have hereunto set my
hand and seal, this Thirteenth day of April, in the year of our Lord One
thousand eight hundred and eighty one.
JULIUS CEASAR LEIGH. (L.S.)
