Year: 1871

page_text: LETTERS PATENT to William Windle Pilkington, of St. Helen's, in
the County of Lancaster, Glass Manufacturer, for the Invention of
IMPROVEMENTS IN APPARATUS TO BE EMPLOYED IN THE MANUFACTURE OF
GLASS."
Sealed the 18th July 1871, and dated the 26th January 1871.
PROVISIONAL SPECIFICATION left by the said William Windle
Pilkington at the Office of the Commissioners of Patents, with his
Petition, on the 26th January 1871.
I, WILLIAM WINDLE PILKINGTON, of St. Helen's, in the County of
Lancaster, Glass Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS TO BE EMPLOYED IN THE MANU-
PACTURE OF GLASS," to be as follows:-
My Invention relates to apparatus for facilitating the operations of
the blower in the manufacture of glass..
The purposes which the said apparatus is principally intended to serve
are,—(1), supporting the blower's tube and the glass attached thereto;
(2), enabling the glass blower to impart the necessary swinging motion

page_text: with comparative ease; (3), imparting rotary motion to the tube and
glass by mechanical agency; and, (4), effecting when desired the blowing
by mechanically compressed air,
.
The framework and operating parts of the apparatus are supported
on three or more carrying wheels, and the whole made portable. In
practice I prefer to form a way with three rails, two placed parallel to
each other on the floor to bear the apparatus, and a third fitted over the
inner rail at a distance therefrom equal to the diameter of the inner
wheel or wheels to prevent the apparatus from canting. A horizontal or
nearly horizontal shaft free to turn in its bearings rests in the aforesaid
framework. All the operating parts are attached to or connected with
the said horizontal shaft. At its outer side are bearings with securing
catches and sockets for the blower's tube. When the tube is fixed in
the said bearings and socket the shaft may be rocked and the swinging|
motion imparted to the cylinder or article being blown. To provide for
giving rotary motion to the blower's tube a sleeve is fitted over the
horizontal shaft and caused to rotate by any convenient power; the
motion is transmitted by toothed wheels, and an intermediate shaft
to the socket containing the blower's tube, the socket and tube being
made to rotate as one piece. When mechanically compressed air is
used a duct supported by the horizontal shaft and fitted with a
regulating valve is connected to the end or an opening in the glass
blower's tube.
SPECIFICATION in pursuance of the conditions of the Letters Patent,-
filed by the said William Windle Pilkington in the Great Seal 2
Patent Office on the 26th July 1871.

Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters 3
Patent, bearing date the Twenty-sixth day of January, in the year of our
Lord One thousand eight hundred and seventy-one, in the thirty-fourth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant.unto me, the said William Windle Pilkington, Her special license
that. I, the said William Windle Pilkington, my exécutors, adminis-/3

page_text: trators, and assigns, or such others as I, the said William Windle
Pilkington, my executors, administrators, and assigns, shall 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 yend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN APPARATUS TO BE EMPLOYED IN THE MANUFACTURE, OF.
GLASS," upon the condition (amongst others) that I, the said William.
Windle Pilkington, my executors or administrators, by an instrument in.
writing under my, or their, or one of their hands and seals, shall
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 William Windle Pilkington, 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 following statement, reference being had to the accom-
panying Sheet of illustrative Drawings, and to the figures and letters of
reference marked thereon, that is to say :-
My Invention relates to apparatus for facilitating the operations of
the blower in the manufacture of glass.,
The purposes which the said apparatus is principally intended to serve
are,(1), supporting the blower's tube and the glass attached thereto
(2), enabling the glass blower to impart the necessary swinging motion
with comparative ease; (3), imparting rotary motion to the tube and'
glass by mechanical agency; and, (4), effecting when desired the blowing.
by mechanically compressed air.
:
The framework and operating parts of the apparatus are supported on
three or more carrying wheels, and the whole made portable. In
practice I prefer to form a way with three rails, two placed parallel to
each other on the floor to bear the apparatus, and a third fitted over the
outer rail at a distance therefrom equal to the diameter of the outer
wheel or wheels to prevent the apparatus from canting. A horizontal
or nearly horizontal shaft free to turn in its bearings rests in the
aforesaid framework. All the operating parts are attached to or con-
nected with the said horizontal shaft. At its inner side are bearings
with securing catches and sockets for the blower's tube. When the

page_text: tube is fixed in the said bearings and socket the shaft may be rocked,
and the swinging motion imparted to the cylinder or article being blown.
To provide for giving rotary motion to the blower's tube a sleeve is fitted
over the horizontal shaft, and caused to rotate by any convenient power;
the motion is transmitted by toothed wheels and an intermediate shaft to
the socket containing the blower's tube, the socket and tube being made
to rotate as one piece. When mechanically compressed air is used a
duct supported by the horizontal shaft and fitted with a regulating*|
valve is connected to the end or an opening in the glass blower's
tube
Figure 1 is a side elevation, Figure 2 a plan, and Figure 3 an end
elevation, all of apparatus constructed and adapted for facilitating the
four operations above named, namely, supporting, swinging, rotating,
and blowing.
The rails on which the apparatus is arranged to run are here shown'
raised from the ordinary floor on the opposite side of the swing hole
from the blower, but it will be obvious these carrying rails may rest on
the ordinary floor level of the gass house, and that the platform on.
which the glass blower stands may be lowered. In these views like.
letters denote the same parts.
a, framework supporting the carrying rails b; c, rail to prevent the
apparatus from canting; d, carrying wheels; e, anticanting pulley;
f, framework of the apparatus; g, shaft, this can be caused to rock by
the workman, and the whole of the over side húnġ parts hereafter
referred to thereby made to swing; h, bearings for the blower's tube i;
j, securing catches. The blower's tube i is shewn detached in side
elevation by Figure 4; two collars k, k³, are formed or secured on it to
prevent slipping during swinging. In practice k might be dispensed
with, and k¹ only used. Surrounding the shaft g is the sleeve which is
here fitted to be rotated by a cord passed over the pulley m; n, bevel
wheel gearing with and giving motion to bevel wheel o secured on the
intermediate shaft p, whose motion is transmitted by the wheels q, q¹ to
the glass blower's tube i. By these parts it will be seen that whilst the
workman is swinging the machine and the glass vessel or cylinder
attached to the tube, such glass vessel or cylinder is or may be caused
to rotate with the glass blower's tube. Compressed air is supplied in

page_text: the arrangement shewn through the duct ", "", and 2 to the glass
blower's tube, that is to say, from an india-rubber tube at r, thence
through the shaft g and tubes 71, 72, a regulating valves being inter-.
posed to moderate the force of and shut off the current of air. The
picce marked 2 is so fitted that it can be withdrawn from the glass
blower's tube, and the mouth of the blower applied.
Figure 5 is a side clevation, Figure 6 a plan, and Figure 7 an end
elevation of a machine with my Invention arranged to perform the
operations of swinging the glass blower's tube and the glass vessel or
cylinder attached thereto, and to blow by mechanically compressed air,
or to blow in the ordinary way. This is the modification I prefer for
present practice. Here a¹ denotes the framework supporting the rails 6';
c', carrying wheels; c', steadying or anticanting pulley; f¹, framework;
g', shaft free to be rocked; h', bearings for the blower's tube; ¹, blower's
tube with one or more collars. Compressed air is supplied when desired
through the ducts r, but in practice I find workmen prefer to blow by
mouth. The rotating of the glass vessel or cylinder is effected by the
workman turning the pipe by hand.
Having now described the nature of my said Invention, and par-
ticularized the same in such manner that others will be enabled to carry
the same into effect, I would have it understood that what I claim iş,
the combination and arrangement of parts, substantially as herein
described for the purposes set forth.
In witness whereof, I, the said William Windle Pilkington, have
hereunto set my hand and seal, this Twenty-fourth day of July,
in the year of our Lord One thousand eight hundred and seventy-
one
WILLIAM WINDLE PILKINGTON. (L.S.)
