PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Attaching or Holding Cocks, Taps
Bottles, or other Vessels Temporarily During the Process of
Testing.
I GEORGE GLYDON of Oozells Street Birmingham, in the County of Warwick,
Brassfounder do hereby declare the nature of this invention to be as follows:-
The object of my invention is the saving of time and labour in connection with
the process of testing under pressure of all kinds of cocks, or taps, glass or other
bottles, or similar vessels of any kind which have one or more open ends.
My improved apparatus is to be used in connection with a force pump or any
similar apparatus for producing pressure, and is connected thereto by means of a
flange or screw, carrying a hollow cylinder in the outer end of which is inserted a
soft washer for making a sound joint with the cocks, taps, bottles, or other vessels to
be tested. Another hollow cylinder sliding on a feather on the first named cylinder
with a coarse screw on its outer circumference and having a part cut away to receive
the articles to be tested; is moved backwards by means of an internally screwed cap,
and is so arranged as to embrace or grip the article to be tested. By moving the cap
in an opposite direction; the article is released.
Much time is thus saved, when compared with other methods of screwing or bolting
down.

I, GEORGE GLYDON, of Oozells Street, Birmingham, in the County of Warwick,
Brassfounder, 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 :-
The object of my invention is the saving of time and labour in connection with the
process of testing under pressure of all kinds of cocks or taps, glass or other bottles,
or similar vessels of any kind which have one or more open ends.
My improved apparatus is to be used in connection with a force pump or other
suitable apparatus for producing pressure, and is connected thereto by means of a
screw or flange carrying a hollow cylinder, in the outer end of which is inserted a
soft washer for making a sound joint with the cocks, taps, bottles, or similar vessels
to be tested. Another hollow cylinder, sliding on a feather on the first named
cylinder; with a coarse screw on its outer circumference and having a part cut away
to receive the article to be tested, is moved backwards by means, of a cap with lever
handle wheel, or other suitable means, and internal screw, and is so arranged as to
embrace or grip the article to be tested.
By moving the lever forward again the article is released..
Much time is thus saved when compared with other methods of screwing or bolting
down,
The accompanying drawings show my improved apparatus. Fig. 1 shews the
apparatus in plan. a is a tank having a shelf b on which, the force pump cand
pressure pipe d are fixed. The pipe d is T shaped and to the part d' is affixed the
apparatus which constitutes the special feature of this invention.
On d the cylinder e slides freely on a feather fixed in d¹. The cylinder e
is screwed on the circumference as shewn, to engage in the large nut f, to which is
attached the handwheel g. The cylinder e is extended lengthwise so as to form the
oblong frame h, which is open at top and bottom, and has the notches i for a purpose
to be described. When the handwheel g and nut fare turned the cylinder e and its
extension slide on d¹.
A soft leather washer j is bedded in the free end of d¹ and a similar washer & in the
oblong frame h.
If an ordinary stopcock, or other double-ended article, be placed within the oblong
frame the said stopcock or other article may be securely fixed between the two
leather washers by turning the handwheel g. Pressure may then be applied by the
pump.
A reverse motion of the. handwheel will release the stopcock or other article when
tested. The drawing shews the mode of fixing suitable for a bibcock. The stirrup

page_text: is dropped into two of the notches i and the bibcock fixed as shewn. At m is shewn
an appliance, which fits into the notches i, for testing double-ended articles, such as
stopcocks, which are not long enough to be fixed between the washers j and k.
The appliance m carries a leather washer n, and a small petcock o.
The oblong
frame h carries a similar petcock p.
These petcocks serve the following purposes.
If the petcock be closed when pressure is applied in testing a stopcock, the body of
the stopcock is tested throughout for soundness by having the said said stopcock
"turned on."
If it be then "turned off" and the petcock opened its efficiency as a stopcock is
tried by the pressure applied, as the petcock allows the escape of the water from one
half of the stopcock.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. The moveable oblong frame and cylinder e as described and illustrated.
2. The applicances and m in combination with h.
3. The general construction of the testing apparatus as described and illustrated.
