An improved Mode and Apparatus for storing Under Fressure and
Delivering Scent or other Liquid in the Form of a Jet or Spray
on the Insertion of a Coin.
I, CHARLES MIDDLETON, of 5 Queen's Place, Chapel Allerton, near Leeds, in the
County of York, Engineer, do hereby declare the nature of this invention to bo as
follows:-
The object of my invention is to produce a mode of distributing, say, scent, with
no trouble to the purchaser-beyond presenting, say, a handkerchief to the jet and
inserting the coin-and this by a simple and inexpensive apparatus.
My mode of storing consists in using what is known as "an hydraulic accumu-
lator" for my reservoir. But instead of pumping into this I raise the weighted ram,
pour in the liquid, and afterwards release the ram.
This ram is weighted to suit the force of the jet required. To avoid leakage
I propose to work with as low a pressure as possible.
I propose using a valve placed more or less in equilibrium so as to require a
minimum force to open & shut it-as this is an important point in my arrangement.
In some cases the valve may work in the liquid and any unbalanced pressure may be
used to keep it tightly pressed to its seat when at rest.
I connect up the valve by leverage, either simple or compound, or by other such
means, so that when, say, a penny is deposited on to the outer end of the main lever
it has power enough to actuate it.
'
The coin is retained on the lever whilst it falls through some prearranged distance.
A tipping device may be used for releasing the coin when required, and also for
guiding it into a receiving box-After the coin is released certain counterweights,
or their equivalent, connected with the levers draw them back to their former position
ready to receive the next coin-If necessary means may be taken to so retard the
fall of the lever, or the return of the valve, or so retain the coin on the lever, that
time is given for the proper quantity of scent to be ejected.

page_text: Another plan of actuating the valve is by "clockwork," the motive power being a
falling or banging weight, released, by the insertion of the coin, for a given interval-
The weighted ram would however eject the liquid.
The valve spindle may be fitted with a swivelling connection so that a workman may
twist the valve round from time to time so as to keep it a good fit; or it may twist
itself in its ordinary work.
The form of rani best suited for my "accumulator" is a hollow one, with an open
top for admitting weights, say, shot, inside. Any form of ram and any mode of
weighting, provided it be properly adjusted to its work, will do.

An Improved Mode and Apparatus for Storing under Pressure and
Delivering Scent or other Liquid in the Form of a Jet or Spray
on the Insertion of a Coin.
1, CHARLES MIDDLETON, of 5 Queen's Place, Chapel Allerton, near Leeds, in the
County of York, Engineer, do hereby declare the nature of this invention and in
what manner the same is to bo performed, to be particularly described and ascertained
in and by the following statement :-
The object of my invention is to produce a mode of distributing liquid; say for
oxample scent which would be delivered to the purchaser with no trouble beyond that
of presenting, say, a handkerchief to the jet and inserting the coin; and this by a
simple and inexpensive apparatus which may easily be kept in working order.
My mode of storing consists in using what is generally termed an "hydraulic
accumulator," or an equivalent pressure-sustaining reservoir; and the apparatus
I use for delivering the liquid consists of a specially arranged valve and a counter-
weighted tipping lever directly acted upon by the falling coin. The valve is designed
with special reference to simplicity and easy working.
In order to fully explain my meaning I have annexed a drawing on which Fig. 1
is a side elevation of an apparatus embodying my mode and arrangements; fig. 2
is a back elevation; and fig. 3 is the corresponding plan. The box or casing, which
may be of any convenient form, is shown in section in these figures. Fig. 4 is an a
enlarged side sectional elevation of the valve, and fig. 5 is its plan-Fig. 6 is an

page_text: elevation of the Valve Lever (which is actuated by the falling coin) showing the toe
of the Valve in contact with the lifting cam. The same letters refer to the same parts
in all the figures.
A is the hydraulic accumulator," or reservoir of liquid under pressure; B is the
plunger which works thro' a gland at A'; C, C, &c. are the weights to give the
required pressure to overcome friction and eject the liquid with the. desired force.
A pressure of about 10 to 15 lbs. per square inch will he found sufficient. The
weights are shown attached to a circular head piece D and they are provided with
heads which slide into slots provided in the head piece as shown-When the plunger
is at the top of its stroke or thereabouts the whole can be twisted round and the
weights can thus be taken off or put on, one by one, from any given point; even
when the space inside the casing is limited. This arrangement keeps the plunger
evenly balanced, with the centre of gravity low in relation to the gland A', so as to
avoid cross-binding friction.
If space allows it the whole of the weights may be cast in one solid piece along
with the head piece, and then fitted over and on to the top of the ram.
The liquid is led up to the valve box E thro' the pipe F, which may be of any
length, and here it is stopped by the "mushroom" valve E¹ on to the head of which
it distributes its pressure which always tends to keep it tightly to its seat.
The valve E which is vertical (by preference), and has a specially long spindle
for the purpose of preventing leakage, extends to the outside of the valve case and
presents its toe to a cam, G2, on the actuating lever G. A light spring at the head
of the valve makes it return to its seat more freely after each movement; it may also
have a stop to prevent it opening too far. The toe may project out far enough to
allow the valve to be handled and twisted round by the attendant when under pressure
so as to keep it tightly to its scat.
In order to avoid the possibility of any deposit, due to any leakage, on the toe or
cam attach what may be termed "an umbrella" above the toe so as to shield it and
the cam, and also the fulcrum, from getting clogged. The umbrella, E, which should
not prevent the twisting round of the valve, is best made circular and of ample size.
The collar and washer on each side of the fulcrum G¹ should be formed somewhat as
shown in fig. 4 so as to further protect it by projecting over it.
Another way of arranging the valve is to turn it upside down; again making the
descent of the actuating lever move it;-in this case by depressing it. A somewhat
stronger spring would then be required to keep it up to its seat in conjunction with
the pressure.
As arranged on the drawing the fulcrum G' of the lever is below the toe and a
little to one side, see fig. 6. An adjustable counterbalance for the purpose of bringing
the lever back to its position of rest is got by screwing one end and mounting
theroon tapped weights G³ which are locked after the adjustments have been
made. A Buffer may be arranged to limit the stroke so as to regulate the quantity
discharged.
The coin (see X, X, X,) is inserted at H and slides down the shoot J which has
guiding edges to load it correctly on to the front end G of the lever which it strikes
with considerable impetus-due to the fall, which must be arranged according to the
requirements of the case. The blow struck by the coin depresses the lever and
the cam G raises the valve and a portion of the liquid is discharged thro' the
opening D³.
The end of the discharging pipe is screwed to receive an ornamental finial rose K
the central opening or openings in which may he made to suit the storage pressure
so as to divide the then solid jet so as to deliver it, if required, in the form of
a spray.
One mode of recharging the reservoir is by unscrewing the rose K from off its
nozzle and coupling thereon a portable force pump. For this purpose the nozzle is
arranged close to the outside casing. The valve E' rises under the pressure from the
pump and the liquid is forced into the reservoir; the valve finally closing when the
pumping ceases,

page_text: Another mode of recharging is as follows;-A funnel is screwed on at D² and
filled with the liquid, then the ram B is raised by any convenient means, say by a rod
passed thro' a special opening used by the attendant only: the raising of the rau of
course draws in the liquid.
ન
Or, a special pipe, stop-valve, and cup, as shown at P, may be arranged for
refilling as last described. Either cup may be graduated as a guide for the
attendant. No air need be drawn in by any of these methods, which it is important
to avoid.
A stop or some equivalent should be fixed to prevent the ram being raised
too far.
The position of the plunger weights may be taken as a guide to the quantity
remaining in the reservoir; and when the lowest point is reached a trigger M, which
turns on a fulcrum at M' may be actuated so as to release a board N and expose the
word "empty." An extention of this trigger-gear may be made to close the coin
entrance if desired.
Fins may be formed on the valve E so as to tond to twist it on its axis as the liquid
escapes, thereby making it take up a new position each time with a view to keeping
it liquid-tight.
Some of the mechanical advantages of this my plan may be thus stated-The
distributing valve may be close to the discharging rose K, regardless of the distance
of the reservoir. Sprays may be got from as many distributing valves as it may be
desirable to arrange and all these may be worked from one reservoir. A free passago
down the shoot is provided; hence paper and other foreign matter mischievously
inserted stands a small chance of fouling the apparatus. The coins fall into any safe
receptacle, access to which need not necessarily be given to the re-charging attendant.
As the coin falls on the lever at a considerable distance from the coin-entrance
succesful tamperings arò next to impossible.
Coins X, X, X, are shown in various positions simply to exemplify their
falling path.
I do not limit myself to the details of the reservoir shown; as any form of ram
and any mode of weighting, provided it be properly adjusted to its work, will do.
For instance a simple modification would be as follows:-
The liquid is poured into any convenient vessel which is then placed in communi-
cation with a column of air which presses on its surface as desired. The air pressure
may be produced and sustained by a
" weighted reservoir," after the manner of the
upper half of a bellows of an organ, with a considerable rise and fall. Or, a weighted
bag and bellows of any kind suitable for producing and sustaining the air pressuro
would do. The air would simply act as a distributer of the pressure and would thus
permit the liquid to be stored in one chamber, say, in a glass bottlo, whilst the other
chamber would be that for producing the pressure. One advantage of this latter
arrangement would be that any leakage caused in producing the pressure would be of
air only.
The liquid would be led away from a point near the bottom of its vessel to the
distributing valve which would be arranged as in the case illustrated. Fresh liquid
would be supplied thro' a special pipe, valve, and cup as already described; the air
reservoir being raised and extended would cause the liquid in the cup to be sucked
in and deposited in the vessel 'provided for it, after which the inlet-stop-valve would
he again closed, and tho air reservoir released to put the pressure on again, when all
would be in working order once more.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that I am aware of
the Specification of Letters Patent granted to Percival Everitt No. 10232 of 1887,
and wish it to be understood that I do not claim anything described and claimed
therein but what I claim is ;

equivalent pressure-sustaining-reservoir, and delivering out portions of the same in
