PROVISIONAL SPECIFICATION.
Improvements in Means or Apparatus for Affixing Taps or Valves
in Drums or other Vessels.
1 FREDERICK PORTMAN MUNRO of South Cottage, Thurlow Park Road,
Dulwich in the County of London, Machine Maker do hereby declare the nature
of this invention to be as follows:-
The invention is designed to facilitate the affixing of taps or valves in drums or
other vessels such as oil drums, or for other uses.
As at present generally constructed the stem of the tap is shouldered and the
portion inserted into the threaded hole in the drum is correspondingly threaded,
a washer of leather being interposed between the shoulder and the socket of the
drum but it is found very difficult to secure a tight fit between these parts without
great loss of time and trouble and secure that the tap shall be upright.
To avoid these inconveniences I form the parts of the tap or valve that hold
it in the vessel in a novel manner.
The portions forming the tap proper may be as usual but rearward of the
shoulder the stem is for a certain distance formed cylindrical and of reduced
diameter, then for a short distance of still smaller diameter and for the remainder
of its length this reduced second diameter stem is screw threaded.
Against the rear face of the shoulder is placed around the stem a packing
washer, if desired.
Against this washer on the larger portion of the stem is slidden a flanged
sleeve or socket piece the flange portion is squared so as to fit it to be grasped
and turned by a suitable key or spanner, and the sleeve portion is screw threaded
correspondingly to the female screw thread of the drum or vessel opening into
which the tap is to be fitted, a washer being interposed between the rear of the
flange and the front of the drum socket. The flanged sleeve is secured on the tap
stem by a metal ring or washer removably locked to said stem and a screw nut or
locking piece engaging the rear thread on the smallest diameter of said stem.
Before inserting the flanged sleeve or tap socket in the threaded opening of the
vessel the tap is affixed in said sleeve with adjusted frictional holding by means
of the said locking piece and proper adjustment of the tap can be attained without
trouble or loss of time, with great efficiency.

5 Improvements in Means or Apparatus for Affixing Taps or Valves
in Drums or other Vessels.
I FREDERICK PORTMAN MUNRO, of South Cottage, Thurlow Park Road,
Dulwich in the County of London, Machine Maker do hereby declare the nature
of this invention and in what manner the same is to be performed, to be
O particularly described and ascertained in and by the following statement:--
The invention is designed to facilitate the affixing of taps or valves in drums
or other vessels such as oil drums, or for other uses.

page_text: As at present generally constructed the stem of the tap is shouldered and the
portion inserted into the threaded hole in the drum is correspondingly threaded,
a washer of leather being interposed between the shoulder and the socket of the
drum but it is found very difficult to secure a tight-fit between these parts without
great loss of time and trouble and at the same time to ensure that the tap shall
be upright in its position.
To avoid these inconveniences I form the parts of the tap or valve that hold it
in a novel manner.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shows by a side view a tap having my improvements applied thereto.
Fig. 2 shows the same by a front view.
Fig. 3 shows by plan view a portion of the tap rearward of the shoulder suitably
formed to receive my improvements.
Fig. 4 shows by front view and Fig. 5 by side view partly in section—a sleeve
or socket piece to be hereinafter described.
Figs. 6 and 7 are details.
The portions forming the tap proper may be as usual but rearward of the
shoulder a the stem 6 is for a certain distance formed cylindrical and of reduced
diameter, then for a short distance c of still smaller diameter and for the remainder
of its length this reduced second diameter stem c is screw threaded. Against the
rear face of the shoulder is placed around the stem ba packing washer dif
desired. Against this washer d on the larger portion of the stem is slidden
a flange sleeve or socket piece e the flange portion e' is suitably formed so as to fit
it to be grasped and turned by a suitable key or spanner fitting the studs or
fingers e and the sleeve portion is screw threaded at e correspondingly to the
female screw thread of the drum or vessel opening into which the tap is to be
fitted, a washer being interposed between the rear of the flange and the front of
the drum socket. The flanged sleeve e is secured on the tap stem by a metal
ring or washer g removably locked to said stem and a screw nut or locking piece h
engaging the rear thread c¹ on the smallest diameter c of said stem. The ring or
washer is provided with an inwardly projecting key or feather g' which slides in
a correspondingly shaped slot c² formed in the tap stem thus preventing the parts
from being displaced should the tap be turned in its socket in a direction liable to
uuscrew its holding parts.
Before inserting the flanged sleeve or tap socket e in the threaded opening of
the vessel the tap is affixed in said sleeve with adjusted frictional holding by
means of the said locking piece h and proper adjustment of the tap can be
attained without trouble or loss of time with great efficiency.
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 :-
The construction and arrangement or combination of the parts of means or
apparatus for affixing taps or valves in drums or other vessels substantially as
and for the purpose set forth and shewn by the drawing.
