Commercial Traveller do hereby declare the nature of this invention to be ag
follows:-
A tap of the general nature of a gas tap, iz. which is turned on and off, by the
action of turning of fixed key. To this key is fixed a bar or lever worked by a spring,
on turning the key to turn tap off, the top of bar or lever goes into a slot in body
of key, to turn tap on it is necessary to press bottom of bar or lever to release
the top from slot, having done so the key is moved round in the usual way.
idea of this invention is to prevent taps being turned on by accident or carelessness,
an intended action must take place to turn tap on. This principle in all its
application to all and every kind of taps particularly gas taps.
A
The
An Improvement in Taps.
1, FREDERICK GEORGE FENDER formerly of Inverness House Ranusden Road
Balham in the County of Surrey but at present of No. 14 Rydevale Road,
Bedford Hill Balham aforesaid Commercial Traveller 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:-
My invention refers to taps or cocks such as are used for turning on or off or
regulating the supply of gas and other fluids. The cock or tap is provided with
"off" a bar
a key or plug having a handle in such manner that on turning the tap
or lever is actuated by a spring or other equivalent and goes into a slot so that in
order to be able to turn the tap on it is necessary to press the bottom of the bar
or lever before the plug can be moved round in the usual way, the object of the
invention being to prevent taps from being turned on by accident or carelessness.
Figure 1 of the accompanying drawings represents a tap or cock such as is
usually applied to gas brackets or the like. Fig. 2 is a detail inverted plan view
for the purpose of showing the slot in the body of the tap. The plug A is provided
with a double armed lever C the lower part of which hangs close to the handle
of the plug so that on turning on for allowing the fluid to pass, it is easy for the
fingers to hold both the lower part of the lever and the handle of the plug in
such manner that the upper end c of lever shall by reason of its being pivotted
at a move out of the slot E in the outside of the body of the tap and permit
of the plug being opened. The lever is kept normally so as to tend to engage
in the slot by means of a spring D in a recess in the plug A and pressing on
the cranked part of the said lever. The end c of the lever C as shown in Figure 2

page_text: serves as nighting pin limited in its movement to the part circular nighting slot to
prevent the tap from being turned too far.
Figure 3 shows a modification wherein the lever C is pivotted to the body of
the tap and provided with a knob within easy reach of the handle of the plug A.
In this case the spring D is in a recess in the body of the tap and the slot E is
formed in the edge of the bending round the plug just above the handle. a' is
the nighting pin to limit the amount of revolution of the plug A.
If the lever
be sufficiently weighty the spring may in some cases bo dispensed with.
Figure shows another modification in which the weight of the lower part of
the lever C is relied upon to press the upper part e into the slot E in the body B
of the tap.
As described with reference to Figures 1 and 2 the lever C is
pivotted to the plug A and works in the recess therein as shown.
Figure 5 shows very much the same construction except that the weighted
lever C is pivotted in a slot or recess which goes right through the plug A, the
upper end of the lever takes into a slot in the body B of the top. The pin a
on which the lever C is pivotted also serves as the nighting pin to limit the extent
of revolution of the plug A.
Figure 6 shows a tap in which the lever is counterweighted and pivotted in the
plug Ans described with reference to Figure 5 but it has in addition another lever
arm C in one therewith which on being pressed swings into the space formed by
the ring shaped handle of the plug and thereby releases the end a from the slot
in the body of the tap.
C
Figure 7 shows a tap wherein the lever C has a counterweight at its lower end.
It is pirotted at a to the body B of the top and the part e takes into a slot E in
the circular beading in the lower part of the plug A. In order to unluck the tap
the lower end of the lever is pushed up and thereby releases the part e from the
slot so that the plug can be turned.
Figures 8 and 3 show a tap which is particularly applicable to gas stove.
In this case the handle of the plug serves for counterweight. It is pivotted at a
and its lower end extends downwards and works in a vertical recess in the plug.
The slot E is in the body of the tap. In order to release the tap, all that one
requires to do is to raise the handle as shown in Figure 8 whereupon its lower
end moves up radially out of the slot E and the tap can be opened as far as desired.
Immediately the handle is released it naturally falls down as far as the lower arm
of the lever will allow it as shown in Figure 8 and when the tap is shut off the
lower arm e falls into the slot in the body B and there locks the plug A. a is the
nighting pin which limits the revolution of the plug.
Figure 9 shows how the counterweighted lever may be applied to a tap placed
vertically. The lever C is pivotted at a in a recess in the plug A, the pin a serving
also as the nighting pin.
Figure 10 shows a bar or bolt applied to a tap of which the plug is vertical and
working by gravity. The bend at the lower part of the plug A has a slot therein
arranged to come fair with the part e of the bur C and when it is desired to turn
on the tap the bar C is pressed upwards into its housing in the body B of the tap
until the recess in the bar therein comes fair with the bead on the plug A whereupon
the tap may be turned. In order to apply this locking device to a tap arranged in
such manner that the weight of the bar would not tend to cause it to come out of
its housing, it may be provided with a helical or other spring in the housing or
chamber and behind the bar which would be made proportionally larger.
Figure 11 represents a similar bar locking device, but applied in a housing in the
plug A instead of in the body part 1 of the tap. The part c takes into a slot E
in the body of the tap a spring may naturally also be applied in this case to actunte
the bar Cand I have shown this in:-
Figure 12 which is a modified form of tap with an extended bar C mounted in
a recess in the plug A and having a rod or stud d on which is mounted a spring D
which tends to force the bar C out and to cause the partc to take into the slot E
in the body B.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. A tap or cock consisting of a plug A and body part B having a slot E on the
outside thereof and a double armed lever C pivotted in the plug A actuated by a
spring D and with part c adapted to take into the slot when the tap is shut off
substantially as described with reference to Figures 1 and 2.
2. A tap or cock consisting of a plug A having a slot E and body B on which
is mounted a lever C actuated by a spring D or by its own weight with a part c
adapted to take into the slot when the tap is shut off substantially as described
with reference to Figure 3.
3. A tap or cock consisting of a plug A having a weighted lever C with a
part c adapted to take into a slot E in the body part B substantially as described
with reference to Figures 4, 5, 6, 8 8 and 9.
4. A tap or cock consisting of a plug A having a slot E and a body part B
having mounted thereon a weighted lever C of which the part c takes into the
slot E substantially as described with reference to Figure 7.
5. A tap or cock consisting of a plug A having a slot E and a body part B
having mounted therein a sliding bar C actuated by gravity or by a spring with a
part which takes into the slot E substantially as described with reference to
Figure 10.
6. A tap or cock consisting of a body part B having a slot E and a plug A
having mounted therein a sliding bar C actuated by gravity or by a spring with a
part which takes into the slot E substantially as described with reference to
Figures 11 and 12.
7. The construction of taps or cocks shown on the drawings.
