PROVISIONAL SPECIFICATION.
Improvements relating to Metallic Tubes used for Heating Liquids.
We HILDYARD GOLDTHORP of No. 149 Westgate Wakefield, Dyer, and
ARTHUR JAMES GOLDTHORP of No. 149 Westgate, Wakefield, Commercial
Traveller do hereby declare the nature of this invention to be as follows:-
:-
Tubes now made of copper, iron or other metallic substances for the purpose of
boiling, heating or otherwise raising the temperature of liquor or liquids are made
with simple apertures or openings allowing the steam to escape. Now the pressure
of the steam against these openings quickly wears away the material around the
aperture & also increases it in size which causes the pipe or pipes to be replaced
before worn at other parts. Now we propose to remedy this defect by tapping the
apertures of tubes before named and then screwing into the same a nipple made of
the same metal as the pipe or any other suitable metallic substance. This nipple
will allow the steam to escape and will save the constant wearing away of the pipe
which now takes place. As any of the nipples become worn they can be replaced
which will be at considerably less cost than having to obtain new tubes as
heretofore.

COMPLETE SPECIFICATION.
Improvements relating to Metallic Tubes used for Heating Liquids.
We HILDYARD GOLDTHORP of 149 Westgate, Wakefield, Dyer and Arthur
JAMES GOLDTHORP of 149 Westgate Wakefield, Commercial Traveller, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
Tubes now made of copper, iron or other metallic substances for the purpose of
boiling, heating or otherwise raising the temperature of liquor or liquids are made
with simple apertures or openings allowing the steam to escape. Now the pressure
of the steam against these openings quickly wears away the material around the
aperture and also increases the latter in size which causes the pipe or pipes to be
replaced before worn at other parts.
Now we propose to remedy this defect by tapping the apertures of tubes before
named and then screwing into the same a nipple made of the same metal as the
pipe or any other suitable metallic substance. This nipple will allow the steam to
escape and will save the constant wearing away of the pipe which now takes place.
As any of the nipples become worn they can be replaced which will be at
considerably less cost than having to obtain new tubes as heretofore. The nipple
may contain one or more holes of any size or desired shape.
In order to better explain our invention we describe the drawing sent herewith.
The same letters refer to corresponding parts in the different figures. Fig. 1 is a
section through the tube. Fig. 2 is an elevation of the tube. Fig. 3 is a plan
through "C" the part marked "A" represents the tube; "B" is a nipple
which may
be made either straight or tapering in the screw inserted into the
pipe containing one hole; "C" is a nipple showing three holes.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The construction of nipples and insertion of the same into old or new tubes used
for the heating of liquor or liquids to allow of the escape of steam and diminish
the wearing of the pipe as hereinbefore described and illustrated by the said
drawing.
