page_text: LETTERS PATENT to William Rose, of Halesowen, in the County of
Worcester, Gentleman, for an Invention of "IMPROVEMENTS IN TAPS FOR
BEER AND OTHER BARRELS AND VESSELS, AND IN APPARATUS FOR
CONNECTING THE SAID TAPS TO AND DISCONNECTING THEM FROM BARRELS
AND OTHER VESSELS."
(Void by reason of the Patentee having neglected to file a Specification in
pursuance of the conditions of the Letters Palent.)
PROVISIONAL SPECIFICATION left by the said William Rose at the Office
of the Commissioners of Patents on the 22nd November 1881.
WILLIAM ROSE, of Halesowen, in the County of Worcester, Gentleman.
"IMPROVEMENTS IN TAPS FOR BEER AND OTHER BARRELS AND VESSELS, AND IN
APPARATUS FOR CONNECTING THE SAID TAPS TO AND DISCONNECTING THEM
FROM BARRELS AND OTHER VESSELS."
In tapping barrels with taps of the ordinary kind, not only is the tapping
effected with considerablo difficulty, but some of the liquid in the barrel is
frequently projected on the person engaged in the tapping.
The object of my Invention is to remedy these inconveniences, and consists of
the improvements hereinafter described, whereby the tapping of a barrel or vessel
is effected with certainty and ease, and the loss of any of the liquid contained in
the barrel or vessel avoided.
I will describe my Invention in connection with a beer barrel.
In the hole in the barrel into which the tap is to be inserted I fix a metallic
tubular lining, the said lining having a flange on that end which occupies the
interior of the barrel. The said lining is introduced into the tap hole from the
inside of the barrel, and for greater security the said lining may be fixed in its
place by a screw flange on the outside of the barrel taking on to the screwed outer
end of the said tubular lining. The interior of the said tubular lining is screwed,
and a screw plug takes into the interior of the said lining so as to close it when
the said plug is screwed home.

page_text: The said plug may be provided with a cork or other washer on its inner end to
enable it more effectually to close the tubular lining. The outer end of the said
plug has a rib crossing its face as a diameter.
The tap is provided with an external screw thread corresponding to the internal
screw thread in the tubular lining, and has a cross depression or groove in its end
of a size and shape suitable for engaging with the projecting rib on the outer end
of the plug.
The screw plug is screwed home into the tubular lining from the interior of the
barrel before it is filled with beer and closes the tap hole. When it is wished to
tap the barrel the end of the tap is made to engage with the outer end of the
screw plug by presenting the end of the tap to the screw plug in such a position
that the rib on the latter takes into the depression or groove in the former. The
tap is then turned in the direction proper to drive home a screw, when the screw
plug retires in the tubular lining the screwed end of the tap taking into the said
lining and advancing therein as the plug retires. When the tap has been fully
screwed home in the tubular lining the screw plug has left the tubular lining and
fallen onto the bottom of the barrel. The tap has thus been fixed in the barrel
without the application of force greater than that required to produce the screwing
motion described, and without the loss of any liquid.
