Improvements in Means for Connecting Taps to Soldered Oil Tins
and the like.
, FREDERICK DUNDAS ELDERTON, Surgeon Major, Army Medical Staff, care of
Messrs. Holt & Co., 17, Whitehall Place, London, S.W., Bankers, 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 tap is an ordinary metal one but has in connection with the end of the pipe
that enters the oil or other receptacle certain other parts, some fixed and others
moveable.
(1.) Fixed at the extreme end of the pipe is a broad, flat, oblong metal flange,
into and near one end of which, and within the margin, the pipe is inserted.
This flange, in addition to the pipe, has attached to it, and projecting from its
outer surface i.e. the surface facing the remainder of the tap, a bolt and four
stout pins. Except in the immediate vicinity of where it is fixed to the flange
the pipe bears a thread for a nut-thumbscrew to run on. The bolt, which is
fixed into the flange at the opposite end to the pipe, and near the margin, also
bears a thread, and is made of just sufficient length to carry a nut after passing
through the metal plate, about to be described. The pins are situated near the
corners and inside the margins.
(2.) Moveable along the pipe is a metal plate of same size as the flange,-
the pipe passing through a hole in it situated nearer one end than the other,
so that the plate can exactly lie over the flange. This plate is also perforated
with holes corresponding to the bolt and the four pins, so that they can pass into
them when the flange and plate come into apposition-separated only by an
india rubber washer about to be described. Moveable along the thread on the
pipe, but outside the plate, is a nut-thumbscrew.
(3.) There is an indiarubber washer, corresponding in shape to the flange, but
with its centre part removed. It can be slipped on over the flange to lie on its
outer surface, being retained in this position by the four pins.
(4.) There is a nut-thumbscrew for the bolt.
The flange of the tap being oblong, can be passed into an oblong hole smaller
than itself. A hole of the required size having been made in the tin receptacle,
(which has been placed with that side uppermost in which is the opening for the
tap) the flange with india rubber washer attached is passed completely into it,
then rotated a quarter of a turn, and adjusted to the hole by means of the four
pins which project from near its margin. The metal plate is then rotated until
the bolt and four pins enter the holes intended for their reception. The plate
will then fall into its proper position, over lapping the margins of the hole-if
the flange has, during this manoeuvre, been maintained in its proper position―
and this is easily done by keeping a slight drag on the tap while the metal plate
is being adjusted. The thumbscrew should then be screwed home on the holt,
and the other thumbscrew as well, until the margin of the hole has been suffi-
ciently gripped to prevent leakage.
