IMPROVEMENTS IN SHUTTLES AND IN APPA- RATUS FOR MANUFACTURING THE SAME
Year: 1876

page_text: LETTERS PATENT to Robert Andrew Wild, of Walmersley, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN SHUTTLES AND IN APPA-
RATUS FOR MANUFACTURING THE SAME."
PROVISIONAL SPECIFICATION left by the said Robert Andrew Wild at the
Office of the Commissioners of Patents on the 13th November 1876.
ROBERT ANDREW WILD, of Walmersley, in the County of Lancaster.
MENTS IN SHUTTLES AND IN APPARATUS FOR MANUFACTURING THE SAME."
" IMPROVE-
This Invention consists, firstly, in making shuttles from vegetable pulp, such as
is used in the manufacture of paper, instead of from wood as has hitherto been
practised. Shuttles made from vegetable pulp are cheaper, lighter, and more durable
than those inade from wood.
The Invention consists, secondly, in the apparatus which I employ for the manu-
facture of shuttles from pulp.
I form a suitable mould in metal, and having filled it to the required depth with
the vegetable pulp I place it beneath a hydraulic press having a plunger of suitable
form, and upon pumping the water into the cylinder in the usual manner the
plunger will compress the pulp into the mould until it forms a perfectly solid homo-
geneous mass, which when dry can be finished by the ordinary tools.
The mould is made (by preference) in five parts, one forming the side and bottom,
one the other side, and one the inside, the lower part of the latter having two
loose cheeks which form the hollow inner sides of the shuttle.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Robert Andrew Wild in the Great Seal Patent Office on the 11th May
1877.

page_text: This Invention consists, firstly, in making shuttles from vegetable pulp, such as
is used in the manufacture of paper, instead of from wood as has hitherto been
practised. Shuttles made from vegetable pulp arc cheaper and more durable than
those made from wood.
The Invention consists, secondly, in the apparatus which employ for the manu-
facture of shuttles from pulp.
Such being the nature and object of my said Invention, I will now proceed to describe
in detail the manner in which the same is to be or may be performed or carried into
practical effect; and in order that the same may be clearly understood I have
annexed hereunto a Sheet of Drawings illustrative thereof, and have marked the
same with figures and letters of reference corresponding with those in the following
explanation thereof:-
Fig. 1 in the annexed Drawing is a longitudinal vertical section of the mould
and plunger which I employ for this purpose, and Fig. 2 is a transverse vertical
section of the same; Fig. 3 is a plan view of the principal half of the same with
the plunger removed; Fig. 4 is a plan of the whole mould with the plunger in its
place; and Figs. 5 and 6 are side and plan views of the plunger removed from the
mould.
The mould is made (by preference) in five parts, one a, a, forming the side and
bottom, one b, b, the other side, and one c, c, the inside, the lower part of the latter
having two loose cheeks d, d, which form the hollow inner sides of the shuttle.
There are also projections, e, e, on the bottom of the shuttle.
I form the mould in metal screwed firmly together by bolts g, g, and having filled
it to the required depth with the vegetable pulp I place it beneath a hydraulic
press having a plunger f, f, of suitable form, and upon pumping the water into the
cylinder in the usual manner, the mould is forced up, and the plunger will compress
the pulp into the mould until it forms a perfectly solid homogeneous mass, which
when dry can be finished by the ordinary tools. To remove the shuttle (thus
formed) from the mould the bolts g, g, are withdrawn and the side b, b, removed.
The piece c, c, (the lower end of which keeps the convex cheeks d, d, in their place)
is next withdrawn, when the cheeks d, d, can be pressed together and drawn out;
the shuttle is then quite free and can be removed from the mould.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I wish it to be understood that I claim as my Invention,―
Firstly. Moulding shuttles from compressed vegetable pulp, substantially in the
manner herein-before described.
And, Secondly. The peculiar novel construction of the mould employed for that
purpose, as herein-before described and illustrated by the Drawings annexed.
In witness whereof, I, the said Robert Andrew Wild, have hereunto set my
hand and seal, this Tenth day of May, in the year of our Lord Oue
thousand eight hundred and seventy-seven.
