PROVISIONAL SPECIFICATION.
Improvements in or connected with Taps.
We, HERBERT FORSTER and GEORGE TOWLER both of 23, Arlington Street,
Clerkenwell, in the County of London, Engravers, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in or connected with taps and is specially
applicable to those taps that are operated by a spring controlled pusher, rod, or
spindle, and which only remain open so long as the pusher is kept pressed in by
the hand.
According to our invention we provide means whereby the pusher can be kept
pressed in for a longer or shorter time as required, without the necessity of keeping
the hand continually pressed thereon.
These means may consist of a flap or lever hinged or pivotted to the tap and
having its front portion (which may normally rest against the pusher) so bent or
shaped that when said Hap or lever is actuated to open the tap it forces in and
retains the pusher in its inward position until released again by slightly raising the
flap or lever, the lightest touch being sufficient to enable the spring controlled
pusher to immediately assume its forward position by coming against the bent or
inclined portion of the flap or lever and thus raise this latter sufficiently for the
pusher to close the tap. The flap or lever may be furnished with a handle for
enabling it to be more conveniently operated.

COMPLETE SPECIFICATION.
Improvements in or connected with Taps.
We, HERBERT FORSTER and GEORGE TOWLER both of 23 Arlington Street
Clerkenwell in the County of London, Engravers, 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 :-
This invention relates to improvements in or connected with taps and is specially
applicable to those taps that are operated by a spring controlled pusher, rod, or
spindle and which only remain open so long as the pusher is kept pressed in by
the hand.
According to our invention we provide means whereby the pusher can be kept
pressed in for a longer or shorter time as required without the necessity of keeping
the hand pressed thereon.
In the accompanying drawing we have illustrated a simple and advantageous
manner of carrying out our invention when applied to a horizontally arranged
push-tap; Fig. 1 being a side elevation with the pusher in its outward position and
Fig. 2 a similar view with the pusher in its inward position.
The means here shown for effecting our purpose consist of a flap or lever a
hinged or pivotted to the tap at a' and having its front portion so bent or shaped
077

page_text: as to produce an inclined surface or angular piece a² for acting upon the
pusher b.
The inclination of the bent portion a' should be such that when the flap or lever
is fully pressed down and occupies the position shown in Fig. 2. it will just suffice
to retain the pusher in its inward position, so that when it is desired to shut off the
flow from the tap a slight touch in an upward direction is sufficient to release the
parts which then immediately assume the normal position shown in Fig. 1 under
the influence of the spring controlled pusher.
The part as may be utilized for the reception of the designation "hot"
for distinguishing the hot or cold water taps where both are employed.
or "cold"
"
a is a handle with which the bent portion a² may be provided for enabling the
flap or lever a to be more conveniently operated.
The flap or lever a may be so hinged or pivotted to the tap as to prevent its
being forced too far back when the pusher comes forward under the influence of
its spring, in which case said flap or lever will normally occupy the position shown
in Fig. 1 with its inclined portion resting against the pusher. Or if preferred the
hinge or pivot may be such as to allow the flap or lever a to be turned entirely
back and thus lie out of the way when it is desired to operate the tap in the
ordinary manner.
For the purpose of giving additional steadiness to the flap or lever and
preventing lateral strain on the hinge or pivot thereof we may provide the front
of the pusher with guide pieces. between which the bent portion of the flap or
lever could work. Or the guide pieces might be arranged on the bent portion of
the flap or lever which would serve the same purpose.
Instead of having the handle a as shown, the end of the bent portion a³ may
terminate in a tail piece which would answer the purpose equally well.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:-
1. A tap, of the push-type, in which means, substantially as described, are
provided for enabling it to be kept open without the hand being retained upon the
pusher.
2. The combination with a tap, having a spring controlled pusher, of a hinged
or pivotted flap or lever the front portion of which is so bent or shaped as to
constitute an inclined surface for acting upon said pusher substantially as herein-
before described.
3. Our improvements in or connected with taps substantially as hereinbefore
described and shown by the annexed drawings.
