NEW ELECTRICALLY OPERATED VALVE FOR FLUSHING CISTERNS AND FOR OTHER SIMILAR PURPOSES
Year: 1884

page_text: I, MILTON SYER, of 36 Rye Lane, Peckham, London, in the County of Surrey,
Lead Merchant, do hereby declare the nature of said invention for A NEW
ELECTRICALLY OPERATED VALVE FOR FLUSHING CISTERNS AND FOR OTHER SIMILAR
PURPOSES to be as follows:-
The object of my invention is the production of a valve for such purposes as
flushing closets, discharging liquids from cisterns, vats, &c and which shall be
actuated without the usual arrangement of wires, chains, levers, and counterpoise.
The means I employ for putting my invention into effect are, preferably as
follows
The valve proper is connected by a short spindle to the underside of a diaphragm
of india-rubber or equivalent material This short spindle passes through the
diaphragm and carries at its end an armature.
At a suitable distance above the armature is fixed an electro magnet.
Both magnet and armature, are enclosed preferably in an impervious case or
dome to the lower edge of which is cemented or screwed the rubber diaphragm.
The valve is opened by sending a current through the magnet.
As soon as the current is stopped the valve drops on to its seat.

page_text: I, MILTON SYER, of 36 Rye Lane, Peckham, London, in the County of Surrey,
Lead Merchant do hereby declare the nature of my invention for "A
ELECTRICALLY OPERATED VALVE FOR FLUSHING CISTERNS AND FOR OTHER SIMILAR
NEW
PURPOSES," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of my invention is the production of a valye for such purposes, as
flushing closets, discharging liquids from cisterns, vats and the like, and which
shall be actuated without the usual arrangement of wires, chains, levers, and
counterpoise. In carrying my invention into practice, I either mount the armature
of an electro magnet of sufficient power upon the valve proper, or connect it thereto
by a rod or chain whenever it may be more conveniently fixed at a distance from
the valve. The valve is raised by sending an electrical current through the
magnet, which accordingly attracts the armature, and opens the valve. As soon as
the current is shunted off, the valve drops by gravity on, to its seat.
In order that my invention, and the means by which it may be carried into
practical effect, may be thoroughly understood, I will proceed to describe the same
referring in so doing to the accompanying drawing which is to be taken as part of
this specification and read therewith, and in which like parts are marked with the
same reference letter.
The figure is an elevation, partly in section, illustrating my invention as con-
structed for attachment to the bottom of a cistern.
A is an air and water-tight case, of suitable material, in which the magnet B is
fixed. B1, B2, are the terminals, and B3, B4, the conductors.
The case A is screwed to the body of the valve C, and between these I interpose
a diaphragm, D, of india-rubber, or equivalent material, to which the valve proper
is connected as explained further on.
'
The diaphragm. serves to keep the water from the magnet, and also to carry the
valve backwards and forwards in obedience to the impulses which are brought to
bear upon it when in practical use. E is the valve proper, and Fits seat which is
preferably formed in one piece, with the body of the valve. The body of the valve
is suitably grated for the passage of the water.
E is a short spindle passing through the centre of the diaphragm, and by its
junction with the armature G effects a firm union between said diaphragm and the
valve. The due escape of air from the cavity H, when the armature is pulled up,
is provided for by means of a perforation through the armature and valve, and
entering the flush pipe, which is led away in any convenient direction.
The action of the apparatus is as follows: The current is switched on to the
magnet in any convenient way, and from the ease with which an electrical current
can be manipulated, it is clear that my invention is applicable, to circumstances
where a long pull, complicated by the interposition of cranks, would be inconvenient,
if not impracticable. As soon as the current is on, the pole piece, B5, pulls up the
armature, thereby opening the valve. The flow of the water is stopped by
switching off the current, when the valve drops on to its seat.

page_text: I do not confine myself to the exact position of the magnet and armature shewn
in the figure, as it is clear that they may be fixed at some distance from the valve
proper, interposing between the valve and armature suitable mechanical connection,
without departing from the nature of my invention.
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. In an apparatus for controlling the flushing or draw-off valve of any cistern
or the like, the combination of an electro-magnet and its armature with the flush
valve proper, the two latter substantially in one piece, i. e. separated by only a short
spindle, as described with reference to the accompanying drawing.
2. In an apparatus for controlling the flushing or draw-off valve of any cistern
or the like, the combination of an electro-magnet in an air and water-tight case
producing with the body of the valve an air-and-water tight cavity, with a flexible
diaphragm carrying the flushing valve and armature by means of a short spindle
passing through it, through which valve or the diaphragm a small air-relief pipe
passes to the aforesaid cavity, as described with reference to the accompanying
drawings.
3. In an apparatus for controlling the flushing or draw-off valve of any cistern
or the like, the combination of an electro-magnet fixed in any convenient position
and its armature mechanically connected with the flushing valve, as described, with
reference to the accompanying, drawing.
Dated this ora day or February 1885.
