Improvements relating to Locking Taps.
I, EDWARD BRONSDON, Advertising Agent, 238, Brockley Road, Brockley, S.E.
do hereby declare the nature of this invention to be as follows:-
To construct a tap of any shape, size, or pattern upon which I weld cast, mould,
or affix a lug or lugs, to form a hinge and base for the lock; and catch for the
bolt of the same. I then make a small lock to accord with the crutch, faucet, or
plug of the tap; extending to the top of the same, with or without an angle piece
to cover the handle of the same locking it at right angles to the tap, so that it
cannot be used or turned on without the use of the key.
A small disengaged bolt provided in the stem of the lock is pressed by means
of a spring automatically with the closing of the lock into an aperture in the lug
of the tap which locks it securely without the use of the key.
The lug or lugs may be secured to the neck of the tap or taps or to a tube con-
nected to the same by means of clamps or collars, when the latter is more con-
venient than their being cast or moulded with the tap.
improvements relating to Locking Taps.
I, EDWARD BRONSDON, of 238, Brockley Road, Brockley, London, S.E., Adver-
tising Agent, 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 means by which taps may be locked in closed position
to prevent opening by unauthorised persons without the use of a key. The device
I employ for this purpose consists of an arm hinged to the rear part of the tap
having a portion extending behind the handle and adapted when the arm is
turned into operative position to prevent the handle being turned. The arm is
locked in position by a bolt carried in its stem and capable of extending into a
recess in the part carrying the arm. The bolt is provided with a spring which
causes it to lock the arm automatically on the latter being turned into operative
position and to withdraw the bolt a key is required to be inserted into a keyhole
in the arm and turned.
In order that this invention may be more clearly understood reference is had
to the accompanying sheet of illustrative drawings on which

page_text: Fig. 1 is a side view of a tap having my improved locking device applied to it,
showing the device in locking and open position.
Fig. 2 is a section showing the method of locking and Fig. 3 shows the key.
The tap A is of any ordinary construction having a handle a or equivalent
means for turning the plug. Immediately behind the handle the body of the
tap is formed with the lugs B to which the arm C is pivoted. This arm C has
a forward extension c with a plate c¹ which lies behind and covers the handle of
the tap when the handle is turned into closed position.
As described the lock is enclosed within the arm and consists of a bolt D pro-
vided with the spring which causes it when free to spring into the recess
between the lugs B. When in this position the arm is against the handle of
the tap and cannot be pushed back.
To withdraw the bolt a suitably formed key (shown in Fig. 3) is inserted into
the hole in the arm (at the side of the bolt and caused to engage with the
projections on the bolt so that on turning the key the bolt is raised from the
recess and the arm is free to turn out of the way. The action of the key in opening
the bolt is itself sufficient to turn back the arm rendering the operation an ex-
ceedingly simple one. The key can be turned freely without danger of injury
to the lock as if it passes the proper point the bolt simply springs back into lock-
ing position when the key has to be turned again to open the lock. The locking
arm is shown pivoted to lugs cast upon the neck of the tap, but a separate part
may be fixed up on the tap to carry the arm or the arm may be pivoted to any
convenient fixed part.
It will be seen that the action of the device is quite automatic as when the tap
is closed and the arm turned up the bolt, which has been resting upon the inclined
surface between the lugs, is allowed to enter the recess formed to receive it
directly the arm reaches its vertical position or whatever position it may take for
locking purposes.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
(1) An improved means for locking taps comprising a pivoted arm, a locking
bolt within the said arm entering a recess in the neck of the tap when the arm
is turned into locking position and means for withdrawing the said bolt, the arm
being adapted to secure the handle of the tap in closed position, substantially as
and for the purposes specified.
(2) An improved device for locking taps comprising a locking arm pivoted to
lugs upon the neck of the tap, a plate on the arm abutting against the tap handle
and a lock carried within the arm, automatically securing it in closed position,
constructed substantially in the manner described and shown and for the pur-
poses specified.
