An Improved Cap for Cylinders or Receptacles for Containing Liquid
or Gas under Pressure.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
This invention relates to an improved cap for cylinders or receptacles containing
liquid or gas under pressure.
In valves for such cylinders or receptacles the placing of the spanner or key
necessary for opening the valve within the protecting cap presents difficulties.
According to the aforesaid invention the spanner or key, in so far as it
constitutes a separate article, is dispensed with by combining the spanner or key
with the aforesaid cap which for this purpose is provided with a square, pin, slot or
the like.
In carrying this invention into effect the spindle of the valve may be provided
with a square hexagonal or other shaped end which serves to fit the spanner or key
formed at the upper end or any other suitable part of the said cap.
Instead of being hollow the spanner or key may be solid, that is to say
constitute for example a simple square, hexagon or the like on the cap, in
which case the valve spindle is made with a corresponding square, hexagonal or
other shaped hole.

COMPLETE SPECIFICATION.
An Improved Cap for Cylinders or Receptacles for Containing Liquid
or Gas under Pressure.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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:-
This invention relates to an improved cap for cylinders or receptacles containing
liquid or gas under pressure.
"In valves for such cylinders or receptacles the placing of the spanner or key
necessary for opening the valve within the protecting cap presents difficulties.
According to the aforesaid invention the spanner or key, in so far as it
constitutes a separate article, is dispensed with by combining the spanner or key
with the aforesaid cap which for this purpose is provided with a square, pin, slot or
the like.

page_text: In the, accompanying drawing
Figure 1 is a vertical section of a cap constructed according to the present
invention and
Figures 2 to 7 show various forms of the key or spanner formed on the said cap.
Referring to Figure 1 a represents the valve the valve spindle, c the square
or other shaped shank to receive the key or spanner and e the key formed on the
cap K.
According to one form or modification of this invention the spindle 6 of the
valve a is provided with a square end cover which the square socket e on the upper
end of the cap is adapted to fit. The said socket e may if desired be formed at any
other suitable or convenient part of the cap K, as for example at e¹ as indicated in
dotted lines in Figure 1.
Instead of being hollow as in Figure 1, the said key e may be made solid, that is
to say, it may constitute for example a simple square or a three sided figure in
which case the valve spindle 6 will be made with a corresponding recess in its end
to receive the said key e as shown in Figure 2. The said key on the cap K may
however consist, of a three sided recess, as shown in Figure 3, of a plain
rectangular projection, as shown in Figure 4, of two cylindrical projections as in
Figure 5, or the reverse of the latter arrangement, that is to say, two cylindrical
or other recesses as in Figure 6, or as shown in Figure 7 of a cylindrical
projection with a slot therethrough. For each of the above modifications the
upper end of the valve spindle will be made of a form to suit the particular form
of key to be used.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
The improved cap for cylinders or receptacles for containing liquid or gas under
pressure, provided with a key for opening the valve of the said cylinder or
receptacle, arranged at the upper end or at any other suitable part of the said
cap, and having the form of a square, triangle, slot or recess, projection or
the like.
