COMPLETE SPECIFICATION.
Improvements in the Manufacture of Glassware.
I, JOHN MARSHALL HUMPHREYS, of the Village of Trenton, in the County of
Pictou, Province of Nova Scotia, Dominion of Canada, Glass Worker, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
The object of this invention is to provide certain new and useful improvements
in the manufacture of glassware whereby two or more pieces or articles can be
manufactured at the same time by one operator and one operation, thus saving con-
siderable time and labour.
The invention consists principally of an apparatus consisting of a frame carry-
ing a plurality of rotatable blow pipes for gathering and blowing the glass, and a
rotatable air supply pipe for driving the said blow pipes and supplying the same
with air.
The invention also comprises certain parts and details and combinations of the
same as will be fully described hereinafter.
Reference is to be had to the accompanying drawings forming part of this
specification in which similar characters of reference indicate corresponding parts
in both the figures.
Figure 1 is a sectional side elevation of the improved apparatus; and
Figure 2 is a side elevation of part of the same.
The improved apparatus is provided with a frame A formed with a bearing A',
in which is rotatably mounted an air supply pipe B, closed at one end by a plug B',
and adapted to be blown into at its upper end by the operator. The supply pipe B
is provided near its closed end with ports B2 registering with hollow arms A²
projecting from the bearing A¹ and forming part of the frame A, the said hollow
armis A2 being at the place of intersection with supply pipe B, enlarged to form
an air chamber which prevents the supply of air being shut off by or during the
rotation of supply pipe B, the said hollow arms A forming bearings at their outer
ends for blow-pipes C and C₁, having ports C2 in register with the bores of the
arms A2, so that air from the supply pipe B can pass through the ports 12 and
hollow arms A and through the ports C2 into the blow pipes C and C, the said
hollow arms A being at their outer ends enlarged to form air chambers which
prevent the supply of air being shut off by or during rotation of pipes C and C.
The upper ends of blow pipes C and C are closed and the lower ends are adapted
to pass into the molten glass to take up some of it and to blow the glass into the
form of the desired articles by the air passing through the blow-pipe.
The upper ends of the blow-pipes C and C are journalled in a suitable cross-
piece A3 forming part of the frame A. On the lower end of the supply pipe B is
secured a sprocket wheel D, engaged on opposite sides by sprocket chain E, passing
at its ends over sprocket wheels D1, D2, secured on the blow pipes C and C¹, so that
when the frame A is held stationary and the air supply-pipe B is rotated, a
simultaneous rotary motion is given by the said sprocket wheels D D1 and D2, and
the sprocket chain E to the said blow-pipes C and C¹.

page_text: Now it will be seen that by the arrangement described, the two blow-pipes can
be passed simultaneously into the glass to gather some of the glass on the pipes
and to simultaneously blow the glass into the desired article so that two pieces
of glassware can be manufactured at the same time. It will further be seen that
the device can be readily used for pressed ware and moulds.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
-
1. An apparatus for the manufacture of glassware, comprising a plurality of
rotatable blow-pipes for gathering and blowing the molten glass, a rotating air
supply pipe and means for connecting the said blow-pipes with the said air supply
pipe, and supplying the same with air, and also a means for rotating the said blow
pipes substantially as shown and described.
2. An apparatus for the manufacture of glassware, comprising a frame, a
rotatable air supply pipe mounted to turn in the said frame, a plurality of blow
pipes journalled in the said frame and connected by hollow arms with the said
supply pipe so that air can pass from the latter to the blow pipes, and means for
rotating the said blow pipes from the said air supply pipe, substantially as shown
and described.
