I, PERCIVAL EVERITT, of No. 47, Cannon Street, in the city of London, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to the combination with a suitable water-filter of a measuring
tap or apparatus adapted to be operated or released by a coin, so that a person can, on
depositing a proper coin in the apparatus, operate the measuring tap or apparatus and
obtain a predetermined supply of filtered water.

page_text: I, PERCIVAL EVERITT, of No. 47, Cannon Street, in the City of London, 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
This invention relates to the combination with a suitable water-filter of a measuring
tap or apparatus adapted to be operated or released by a coin, so that a person can, on
depositing a proper coin in the apparatus, operate the measuring tap or apparatus and
obtain a predetermined supply of filtered water.
In order to enable my invention to be fully understood I will describe how it can
bo carried into practice by reference to the accompanying drawings, in which
Figure 1 is a front.elevation of a combined water-filter and measuring-tap or
apparatus adapted to be operated or released by a coin according to my invention.
Figure 2 is a similar view to figure 1 with the front of the casing of the apparatus
removed, the lower part of the casing being shown in section.
Figure 3 is a central vertical section taken at right angles to figure I
Figure 4 is a central vertical section drawn to an enlarged scale of the coin-operated
measuring-tap in its closed position.
Figure 5 is a vertical section on the line A, B of figure 4.
Figure is a horizontal section on the line (D of figure 4.
Figures 7 and 8 are similar views to figures 5 and 6 respectively but showing the
tap in its open position.
Similar letters in all the figures indicate similar parts.
The filter which I have shown and which is indicated by the letters a, b, c, d, e
forms the subject of my application for Letters Patent No. 9606 dated 7th July 1887
and will be fully described in the Complete Specification thereof. It is to be under-
stood however that any other filter of suitable construction can be employed.
The filtered water passes through a pipe e into a tank f¹ made with an internal
chamber for containing ice if required in order to cool the filtered water; his a
pipe for the ice water to run off into a receptacle at the bottom of the apparatus.
The measuring-tap or apparatus is similar in construction to that for which a Patent
was granted to George Henry Smith, No. 15,065 dated the 8th December 1885 with
the exception that in the drawings the tap is only adapted to measure one fixed
quantity of liquid and the internal pipes j and k, referred to in the said former Patent,
are therefore not required; the air pipe u leads direct from the casings into the top
part of the tank a and the cone cock and air-holes v, w and of the before mentioned
Patent are therefore dispensed with. The tap is turned by means of a handle j, on
the spindle of which is a bevil wheel / engaging with a similar bevil wheel m fixed
on the spout of the measuring-tap.
2°

page_text: d, (figure 1) are the stops for limiting the movement of the handle when
turned into its open and closed positions. The spout extends into a nozzle n through
which the measured quantity of filtered water is discharged when the tap is opened.
The tap is filled from the tank" through the connection i.
q
The boss o of the bevil wheel is formed with two teeth and q' in which engages
the lower end of a rod p so as to lock the handle in its closed position until freed
by the action of a coin; the rod p is jointed at its upper end to a weighted lever t
pivotted at y
and carrying a coin-receiving and discharging bucket a similar to that
described in my former Patout No. 15,813, datod 3rd December 1886 and similarly
operated by a pin or stop to discharge the coin.
The boss o of the bevil wheel is also formed with a flange a¹ having a projecting
portion 6 on its face, which portion is adapted to bear upon a pin c¹ on the rod p
for the purpose of depressing the said rod and thereby effecting the discharge of the
coin as hereinafter more fully described.
is a shutter for closing the money slit e¹ and preventing the insertion of a coin
whilst the tap is open. The said shutter is carried at one end of a pivotted lever gl
jointed at its other ond to a vertical rod h¹ the lower end of which is forked as clearly
shown in dotted lines at figure 2. This forked end embraces a cam (also shown
clearly by a dotted line in figure 2) fixed on the boss o of the bevil wheel so that
when the handle is moved to the open position the cam will raise the rod h¹ and
thereby move the shutter into a position immediately behind the money slit e¹.
m² is a shoot for conducting the coin from the money slit e¹ into the money
bucket a³.
n is a shoot through which the coin passes when discharged by the money bucket a²
and is conducted to the money receptacle o¹.
plis a tank for receiving waste water and is an overflow pipe for the saine,
discharging into the receptacle .
In order to obtain a measured quantity of filtered water, the tap being closed
and locked, and the parts being consequently in the position shown in figures 1 to 6,
a coin of the proper denomination must first be placed in the money slit e¹, when it
will fall into the money bucket a³ which will be borne downwards by its woight. The
rod p will thereby be lifted free of the toothy and, the handle thus unlocked, can be
moved towards the right hand so as to open the tap (as shown in figure 8) which will
then discharge its contents through the nozzle n. As the handle is thus moved the
flange a will rotate and its projection will bear upon the pin e¹ and draw down
the rod p, as shown in figure 7. This movement will cause the money bucket a² to
aseend and, by reason of its bottom being tripped by the pin z, to discharge the coin
into the shoot n'. The shutter d, as hereinbefore explained will now prevent another
coin from being inserted in the apparatus until the handle is moved back to close the
tap, when the rod p will ride over the teeth 7, q' and again fall into its locking
position shown at figure 5.
The handle cannot again be operated until another coin has been inserted in the
apparatus.
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 what I
claim is
1. The combination with a filter of suitable construction, of a measuring-tap or
meter operating to deliver a predetermined quantity of liquid from the filter at each
discharge, and a coin-operated mechanism serving to allow the tap to be operated.
2. The combination with a filter of suitable construction, of a refrigerator for cooling
the liquid to be filtered, a tap operating to deliver a predetermined quantity of liquid
at each discharge, and a coin-operated mechanism serving to allow the tap to be
operated.
3. In a combined filter and coin-freed measuring-tap the arrangement of mechanism
whereby the handle of the tap is locked and unlocked substantially as hereinbefore
described and illustrated in the accompanying drawings.

page_text: 4. In a combined filter and coin-freed measuring-tap, the shutter for blocking the
money slit so long as the measuring-tap is open and mechanism for operating the
said shutter, substantially as herein before described and illustrated in the accompanying
drawings.
5. The improved combined water-filter and measuring-tap hereinbefore described 5
and illustrated in the accompanying drawings.
