PROVISIONAL SPECIFICATION.
Improvements in Unions for Glass Piping.
I THOMAS HOWELL WILLIAMS of 10 Ascham Street Kentish Town in the
County of Middlesex Mineral-water Manufacturer and Manufacturing Chemist
do hereby declare the nature of this invention to be as follows:-
My invention is for improvements in unions for glass piping.
The object of my invention is to form a union between two or more lengths of
glass piping in such a manner that same may be readily connected & disconnected
& to do away with all metallic contact.
The manner in which I effect this object is by casting or moulding a male screw
of metal or other suitable material of sufficient length round outside the end of each
pipe such end and outer screw being preferably flush with each other & then joining
the two by means of a cap or cylinder lined with a corresponding female screw of
similar material into which the screws on the ends of the two pipes can be inserted
& screwed up so as to form a gas and water tight joint.
The same object may be also effected by having the male screw on the end of one
pipe only & casting or moulding a flange on to the pipe to be joined therewith such
flange being preferably flush with the end thereof the outer cap or cylinder having
been previously passed on to the pipe and being constructed with a shoulder at its
further end so that when the cap or cylinder is screwed on to the pipe to be
attached such shoulder presses up tightly against the flange an india-rubber washer
or other suitable seating being inserted between the shoulder & the flange if
desired.
The end of each glass pipe should preferably be ground so as to form a true
surface in a plane at right angles to the axis of such pipe or a rubber or other
washer or a small quantity of suitable cement or composition may be placed between
the terminal edges of the glass so as to prevent leakage.
Corresponding portions of the threads of the male & female screws may be cut
away if desired so that the cap or outer cylinder may be passed over the screwed
attachment on the end of the pipe or pipes & the union effected by a partial turn
of such cap or outer cylinder.
The cap or outer cylinder may be fitted outside with lugs or other projections or
canted or keyed for greater convenience in tightening the joint.
Dated this 8th day of November 1892.

Improvements in Unions for Glass Piping.
I THOMAS HOWELL WILLIAMS IDRIS formerly Thomas Howell Williams of
Pratt Street Camden Town in the County of Middlesex Mineral Water Manu-
facturer and Manufacturing Chemist, I having changed my name by a Deed Poll
dated the 1st day of February 1893 and enrolled in the Central Office of the
Supreme Court on the 3rd day of February 1893 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:-
My invention is for improvements in unions for glass piping.
The object of my invention is to form a union between two or more pieces of

page_text: glass piping in such manner that same may be readily connected and disconnected
and to do away with all metallic contact.
The manner in which I effect this object is by casting contracting or moulding a
male screw of metal or other suitable material of sufficient length round outside of
the end of the pipe such end and outer screw respectively being preferably flush
with each other Figures 1 and then joining the two by means of a cap or cylinder
lined with a corresponding female screw of similar material Figures 2 into which
the screw on the ends of the two pipes can be inserted and screwed up so as to form
a gas and watertight joint or connector.
The same object may be also effected by having the male screw on the end of one
pipe only Figures 3 and casting contracting or moulding a flange on to the end of
the pipe to be joined therewith Figures 4 such flange being preferably flush with
the end thereof the outer cap or cylinder Figures 5 having been previously passed
on to the pipe and being constructed with a shoulder at its further end so that
such shoulder may press up tightly against the flange an india-rubber washer or
other suitable seating being inserted between the shoulder and the flange, if
desired.
The end of each glass pipe should preferably be ground so as to form a true
surface in a plane at right angles to the axis of such pipe or a rubber or other
washer or a small quantity of suitable cement or composition may be placed between
the terminal edges of the glass so as to prevent leakage Figures 6.
Corresponding portions of the threads of the male and female screws may be cut
away if desired Figures 7 and 8 so that the cap or outer cylinder may be passed
over the screwed attachment on the end or ends of the pipe or pipes and the union
effected by a partial turn of such cap or outer cylinder.
The female screw may even be reduced to a single thick thread Figures 9 or be
replaced by two or more lugs or projections preferably two the outer cap or
cylinder being constructed with a corresponding suitably inclined recess or slot
Figure 10 to receive same as illustrated in the ordinary bayonet catch.
The cap or outer cylinder may be fitted outside with lugs or other projections or
canted or keyed for greater convenience.
The accompanying drawings illustrate the nature of my invention but I make no
claim as to the forms of the metal portions of the unions above & in the said
drawings described all of them being in more or less common use in joining metal
pipes. Nor do I make any general claim to obviating all metallic contact.
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. The improvement in connecting glass piping in the manner substantially as
herein before described.
