page_text: I, JOHN MACDOUGALL, of 8 Minerva Street, Glasgow, Lanarkshire, Property
Agent, do hereby declare the nature of the said Invention to be as follows:—
This Invention has reference to a simple improvement in the construction of the
joint or key parts of the swan neck cranes or taps used in conjunction with a
Lambert valve" or other screw down valve, for the service or supplying of water
to the sinks or cisterns of domestic and other houses; and in which it is the valve
which shuts off and regulates the supply of water, while the swan neck crane or
tap is supplied with the water in nearly all its positions, and is essential for
raising and directing the stream of water supplied to it by the valve, into the
kettles or other vessels placed in the sink to be filled with the water. In this way
it happens very frequently that the water is not quité shut off by the valve
and keeps running continuously through the swan necked crane, which when
turned forward and down only wastes the water by allowing it to drain off through
the sink. But when the crane or tap is turned back over the wood fittings of the
sink which is also very frequently done and neglected in this position, sometimes
even in the night time, so that the water trickles down between the wood and the
iron sink, which is seldom able to be kept tight, and being all enclosed by wood-
work is frequently unobserved for hours at different times, until great damage is
done to the woodwork, and the floors and ceilings below become destroyed, causing
much waste to properties and expense in repairs. The object of my improvements
is to prevent this taking place.
And the nature and novelty of the Invention consist in fitting a projection or
stop on the stationary socket or case of the crane or tap, and forming another
projection or pin on the swivelling boss or key part in the path or plane of the
stationary one, which are so placed or divided in relation to each other round the
circle, as to allow the swan neck of the crane to turn down into the sink after use,
but the projections by coming in contact with each other as a stop hinge only
allows it to turn up and back beyond the perpendicular position sufficient to stand
and direct the stream of water as required, but with the outlet nose of the neck
still over the sink, so that even if left standing with the water on at the valve, it
all turns into the sink below and cannot get on to the woodwork.

page_text: This arrangement of stops to the swivelling joint part of swan neck tube water
cranes or taps, may be fitted at either the outer head end, or the inner point and
nut end, and when fitted at the latter, the stop on the turning part might be in the
form of a screw pin inserted by pliers into the side of the key part near the washer
below the nut, or this pin might be screwed or riveted into the washer, when that
turned with the crane or tap, and project into the plane of the projecting stop on
the stationary case of the crane or tap.

Improved Safety Appliances for Swan-neck Tube Water Taps.
I, JOHN MACDOUGALL of 8 Minerva Street, Glasgow, Lanarkshire, Property
Agent, do hereby declare the nature of my invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement in writing, réference being had to the accompanying
Drawings and to the letters and figures marked thereon; that is to say-
•
Referring generally to the Figures 1 and 2 of the Drawings, my said invention
has reference to a simple improvement in the constraction of the joint or swivelling
'key parts A, B of the swan-neck tube taps of cranes A³, used in conjunction with
'a "Lambert" valve O, or other screw-down valve, for the service or supplying of
'water to the sinks or cisterns Z of domestic and other houses; and in which it is the
valve which shuts off, and regulates the supply of water through the inlet branch
pipe C The swan neck tube tap or crane A, A² is supplied with the water in all
its positions, and is used, or essential, for raising and directing the stream of water
'supplied to.it by the valve C into the kettles or other vessels placed in the sink Z
to be filled with the water. In this way it happens very frequently that the
water is not quite shut off by the valve C and keeps running continuously through
"the swan-neck tube or crane A, which when turned forward and down, as indicated
in dotted lines in Figure 1, only wastes the water by allowing it to drain off
"through the sink Z. But when the tube crane A¹ is turned back over the wood
fittings of the sink Z, which is also very frequently done, and neglected in this
position, sometimes even in the night time, so that the water trickles down between
the wood and the iron sink Z which is seldom able to be kept water tight, and
being all enclosed by woodwork, is frequently unobserved for hours 'at different
times, until great damage is done to the woodwork, and the floors and ceilings
below become destroyed, causing much waste to property and expense in repairs;
The object of my improvements is to prevent this taking place..
.

page_text: And in order that the nature of my said invention, and the mode and means of
putting the same into effect or practice, may be properly understood, I shall now
proceed to describe the several Figures on the sheet of Drawings I have hereunto
appended for that purpose, the same reference letters being used to indicate like or
equivalent parts in all the Figures where shown.
Figure 1, is a sectional elevation, to about half the natural size, of one end
of an ordinary house sink Z and wood work z shown as fitted with a swan neck
tube crane or valve tap A A', B, C, having one arrangement of my improved
fittings a, b, as applied thereto, and shown in section on the line 1-1 of the
swivelling joint key part A in Figure 2, which is a plan view (corresponding to
Figure 1) of the whole tap so fitted, all to show more clearly the new or improved
stop safety fittings a, b, for preventing the water getting over the sink down
through the wood work.
Figures 3 and 4 are respectively a full sized elevation and a plan of the
swivelling joint key parts A, B, of a swan-neck tube crane or valve tap A. A¹
B C, showing a modification of my improved safety stop fittings a, b, as applied to
the inner or retaining nut and washer end of the joint key parts.
Figures 5 and 6 are a side elevation and a plan, corresponding to each other, of
a different but equivalent modification of my improved safety stop fittings a, b, as
also applied to the inner washer and nut end of the tap parts A, B.
Referring particularly to Figures 1 and 2:-The nature and novelty of my
invention and mode of putting the same into effect consist, in fitting a projection
or stop 6 on the stationary socket or case B of the crane or tap A A¹, and in
forming another projection or pin a on the swivelling boss or key part A in the
path or plane of the stationary part b. These parts a and b are so placed or
divided in relation to each other round the circle, as to allow the swan-neck A¹ of
the crane or tap A A¹ to turn down into the sink Z, after use without touching it.
But when the swan-neck tube A¹ is turned up the projection a comes in contact
with the other end of the projection b, and acting as a stop hinge, only
allows it to turn up and back sufficiently beyond the perpendicular, as shown in
sharp lines in Figure 1, to stand and direct the stream of water as required, but
with the outlet nose of the neck tube A¹ still over the sink, so that even if left
standing with the water on at the valve C, the water would all run into the sink. Z
below, and cannot get on to or down through the wood-work z, to injure the
property as was the case heretofore.
This arrangement of safety stops a and b to the swivelling joint part A, B, of
swan-neck water tube taps or cranes, may be fitted either at the outer head end
(as described, and shown in Figures 1 and 2) or at the inner point and nut end, as
shown in the two.arrangements-Figures 3 and 4, and 5 and 6, respectively.
Referring to Figures 3 and 4, when thus fitted at the nut end, the stop a, on the
swivelling part, might be made in the form of a pin a screwed, riveted, or other-
wise secured into the washer 'A' shown detached in Figure 3a, when that turned
with the crane or tap A secured below the end nut A³. This pin a projects into
the plane of the projecting stop 6 formed on the end of the stationary case B of the
crane tap A B; all so that when the swan-necked tube A¹ is turned up it is
stopped with its head over the sink Z, so that the water cannot escape over the
woodwork when left running; and when turned down the pin a also comes in
contact with the under end of the stop b and prevents the crane or swan-neck
tube A from striking the side Z¹ of the sink Z. The same effect could also be
obtained in this arrangement, by screwing or otherwise securing a pin a into the
small end of the turning key A in the plane of the stop b.
Referring to the arrangement of my safety stops for these swan-neck or tube
cranes shown in Figures 5 and 6, the movable stop a is here formed as a segmental
lip on the outer edge of the turning washer A, projecting back over the outer
end of the stationary tap case B in the plane of the segmental stop b, in this case
formed on the outer end of the said stationary case B; both segments a and b
being so divided and secured that their respective ends meet to stop the swan-neck

page_text: tap or crane A¹ in its upward position over the sink Z and so prevent the water
getting on to the wood work 2, and when turned down prevent it from striking the
side Z¹, of the sink Z, all as explained in reference to the modifications previously
described.
Having now described the nature and mode of performing my said Invention, or
improved safety appliances or fittings for water service tube taps or swan-neck
cranes; I have to state that I do not desire to claim the application of stops to
ordinary stop cocks for gas water and other fluids, which turn on or shut off the
current of fluid through them, and which stops are applied for the different
purpose of being sure when the ports of such cocks (which are hid within) are full
open and properly or quite shut; but what I consider novel and original and
therefor claim is :-
First. The construction and adaptation of safety stop appliances or fittings a, b,
for and to water service swan-neck or tube taps or cranes A A' B, C, having
seperate shut off valves C, all for the new purposes and advantages of limiting
the direction of discharge of the water within the sink or vessel to which they
are fitted and preventing it from escaping over the wood work, or into the house,
when the valve is left open, and substantially as herein described, or as shown in
the Drawings.
Second. The adapting and applying of safety stop appliances or fittings a, b, to
water service swan-neck or tube taps or cranes A A¹ B, C, (having seperate shut off
valves C) all substantially as and for the new purposes and advantages herein
described, in reference to the accompanying Drawings.
