[Communicated to him from abroad by Messieurs de Poilly, de Fitz-James and
de Brigode of Paris in the Republic of France]
This Invention relates to the mechanical blowing of bottles and other articles of
glass, and consists in a novel arrangement of valve apparatus for admitting
compressed air from a suitable reservoir to the blowing iron.
The apparatus consists of a hollow handle into which is fitted a socketted tube,
the socket portion being outside the handle. The internal shoulder of the socket
forms the valve seat for a disc or other valve. This valve is formed with a
triangular stem of sufficient length to project beyond the tube when the valve is on
its seat, and which forms a guide to keep the valve in its place. To the socket is
adapted in any convenient manner a nozzle to which a suitable pipe in connection
with the compressed air reservoir is attached.
The free end of the handle is coned out to receive the stem of the blowing iron,
and is made of such form and dimensions as will ensure a tight joint and prevent
the escape of air during the blowing operation.
When it is desired to blow, the handle is applied to the blowing iron and the
valve stem comes in contact therewith. As the handle is pushed on to the iron

page_text: until it finds a bearing thereon, the valve is opened and admits air to the blowing
iron. Directly the handle is removed from the iron the pressure of air on the
back will close the valve.
By the use of the above described apparatus, cocks for opening and closing the
air passage are rendered unnecessary.
It may be remarked that the form and arrangement of this apparatus is capable
of various modifications, but whatever the form or arrangement, the following
conditions are essential, viz; that the arrangement of that part of the apparatus
intended to receive the stem of the blowing iron shall be such as to form with the
iron a tight joint and that the valve shall be opened by the insertion of the iron
and closed by the pressure of the compressed air.

HENRY EDWARD NEWTON of the Office for Patents 66 Chancery Lane in the
County of Middlesex Civil Engineer "IMPROVEMENTS IN APPARATUS TO BE USED
IN THE MANUFACTURE OF BOTTLES AND OTHER ARTICLES OF GLASS " a. Commu-
nication to me from Abroad by Messieurs de Poilly de Fitz James and de Brigode
of Paris in the Republic of France
This Invention relates to the mechanical blowing of bottles and other articles
of glass, and consists in a novel arrangement of valve apparatus for admitting
compressed air from a suitable reservoir to the blowing iron.
This apparatus consists essentially of a hollow handle of caoutchouc or other
suitable material in which a metal valve is arranged in such a manner as to permit
of the blowing iron being placed at any desired moment and without inconvenience
in communication with a reservoir of compressed air.
The arrangement of this handle is such that the mere fact of adapting the end
of the blowing iron to the handle will cause the opening of the valve and con-
sequently allow the admission of the compressed air to the article that is to be
blown, while withdrawing the blowing iron will allow of the closing of the valve
under the action of the compressed air in the reservoir with which the handle is
connected by a flexible pipe.
It will be seen that in this manner the intervention of the workman to effect
the different operations of opening and closing of the valve to admit or cut off the
air from the article being treated is unnecessary, as the excessively simple arrange-
ment about to be described dispenses in effect with the employment of cocks or
other means, the manipulating of which is inconvenient to the workman who by
the present system can introduce or cut off the compressed air without any
inconvenience and with the greatest precision into or from the object to be blown,
of whatever kind it may be.
In the accompanying Drawing Fig: 1 is a longitudinal section of the improved
valve apparatus. Fig: 2 is a cross section on the line ab Fig: 1, and Fig: 3 is a
longitudinal section of the apparatus with the blowing iron in position.
A is a hollow handle of caoutchouc and of such form and dimensions as will
permit of its being conveniently held in the hand of the workman. Into the
interior of this handle is fitted a socketted metal tube B in which is arranged a
valve C of bronze, steel or other suitable material the shoulder of the socket
forming the valve seat.
The valve C is guided in its movement by a triangular stem D secured thereto
and of such a length that when the valve is on its seat the stem will extend a short
distance beyond the end of the tube B, as seen in Fig: 1.
The extremities of the guide stem D are made chisel-edged so as to obstruct as
little as possible the opening in the blowing iron when the iron is applied to the
handle.
כי
To the socket end of the tube B is secured in any convenient manner a metal
lining E to which is secured an india-rubber. or other flexible pipe in connection
with a reservoir of compressed air.
The free end of the handle A is coned or hollowed out as at G to receive the
stem of the blowing iron H and to form at this point with the iron an air-tight
joint. The insertion of the iron H in the handle will force up the stem D and
open the valve C, as seen at Fig: 3.

page_text: It will thus be seen that in order to blow an article the workman has only to
take hold of the handle A with one hand and the blowing iron H with the other,
and apply the conical portion G of the handle to the stem of the iron H.-The
extremity of the iron H will push in the stem D to open the valve C and the
blowing operation is effected with the greatest facility. As soon as the workman
separates the handle A from the iron H the valve will close automatically under the
pressure of the compressed air in the reservoir, and thus the issue of air from the
reservoir while the apparatus is not in use will be prevented.
It will be understood that this apparatus may be of any form or arrangement
suitable for realising the conditions above indicated.-The handle A may be of any
suitable material provided that the part intended to receive the iron H is arranged
in such a manner as to form an airtight joint at this point.-The valve C contained
in the handle A may be arranged in any other manner provided the essential
feature viz: that of being opened under the pressure of the blowing iron and closed
automatically when the iron and handle are separated is maintained
Having now described this Invention for "Improvements in apparatus to be used
in the manufacture of bottles and other articles of glass" as communicated to
me from abroad and explained the manner of carrying the same into effect
I claim:
The apparatus for mechanically blowing bottles and other articles of glass
substantially as herein described and shown in the drawing such apparatus
consisting essentially of a valve arranged to open, and close automatically on
being applied to, or separated from, the blowing iron and contained in a handle
coned or otherwise hollowed out at its free end and connected at its other end by
a flexible tube with a reservoir of compressed air
In witness whereof I the said Henry Edward Newton have hereunto set
my hand and seal the twelfth day of June in the year of our Lord One
thousand eight hundred and eighty three.
