Improvements in and connected with Taps.
I, THOMAS SKURRAY, of 36, Ock Street, Abingdon in the County of Berks,
Analytical Chemist do hereby declare the nature of this invention to be as
follows:-
The present application for Letters l'atent has for its object an improved safety
tap especially applicable as a removable draw-off cock to receptacles containing
liquids under moderate pressure.
The tap or stop cock itself may be of any suitable construction; the shank or
spigot is prolonged to a length proportioned to the thickness of the receptacle at
the point to which it is to be applied, and preferably so that the inner end of the
spigot projects a little into the interior of the receptacle. The end of the spigot
is formed conical, with the broad end outward and of such a diameter that it can
just be inserted into the bung hole or aperture to which it is to be applied. The
shank of the tap is furnished with a screw thread and a nut thereon between the
cone and the tap and a second cone slips loosely over the shank with its smaller
end towards the first cone, and can be adjusted with respect to the same by means
of the nut.
Between the two cones is placed a piece of indiarubber tube or other
compressible material. The application of the apparatus is as follows: The two
cones being separated to their greatest distance apart and the indiarubber
consequently not compressed, the spigot can be inserted into the bung-hole or
let-off aperture. The inner cone is then caused to advance by screwing up the nut,
which compresses the elastic material, and causes the same to tightly grip the hole
and retain the device in place.
For certain purposes the end cone can be made to screw on to the spigot so as to
admit of being adjusted from the inside of the receptacle after the spigot is
in place.

I, THOMAS SKURRAY, of 36, Ock Street, Abingdon, in the County of Berkshire,
Analytical Chemist, 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 present application for Letters Patent has for its object an improved safety
tap especially applicable as a removable draw-off cock to receptacles containing.
liquids under moderate pressure.
The essential feature of my invention consists in the provision of a sleeve of
compressible material on the shank or spigot which after the tap has been inserted

page_text: in the bung-hole or let off aperture may be compressed so as to completely fill said
aperture securing the tap firmly in position.
In the accompanying drawing I have shown how I carry my invention into
practice.
A is the tap or stop cock which may be of any suitable construction; B is a
portion of the side of the receptacle shewn in section B' being the aperture therein,
the shank or spigot A' of the tap is prolonged to a length proportioned to the
thickness of the receptacle at the point to which it is to be applied, and preferably
so that the inner end of the spigot projects a little into the interior of the receptacle
as shewn. The end A' of the spigot is formed conical, with the broad end outward
and of such a diameter that it can just be inserted into the bung hole or aperture B¹.
The shank of the tap is furnished with a screw thread A³ having a nut C thereon,
and a second cone D slips loosely over the shank with its smaller end towards the
conical end A which cone D can be adjusted with respect to the same by means of
the nut C. Between the two cones is placed a sleeve E of indiarubber or other
compressible material.
The application of the apparatus is as follows:-
The nut C is screwed out so that the cone D may be moved as far away as
possible from the cone A2 along the spigot and the sleeve E is consequently not
compressed, as shewn in full lines in the drawing. The spigot can then be inserted
into the bung-hole or let-off aperture. The cone D is now caused to advance by
screwing up the nut, which compresses the sleeve of elastic material E, and causes
the same to expand circumferentially so as to completely fill the hole as shewn in
dotted lines and retain the device in shape.
The nut C is not necessarily made hexagonal as other suitable shapes may be
used such as for instance a wing-nut or a circular nut with a milled edge.
For certain purposes the end cone A' can be made to screw on the spigot so as
to admit of being adjusted from the inside of the receptacle after the spigot is
in place.
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 combination with a tap or stop cock of a sleeve of elastic or compressible
material placed on the shank thereof and means for compressing said sleeve so, as
to cause it to expand circumferentially for the purpose specified.
2. The improved means for securing a tap or stop cock in position substantially
as described with reference to the accompanying drawing and operating as
specified.
