page_text: We THOMAS HOLT and JAMES HOLT Plumbers of 1 Oxford Street Liverpool in
the County of Lancaster do hereby declare the nature of this invention to be as
follows:-
This Invention has for its object, the discharging of the contents of a cistern into
a urinal by means of the weight of the urine discharged into the urinal, and that the
Invention shall be both cheap and serviceable.
(1) A cistern either of the tilting, non-tilting, syphon, or non-syphon kind actuated
or set in motion by means of the weight of urine caught in a cup or receiver suspended
in the waste pipe of the urinal or a pipe connected therewith, and which cup or
receiver also receives the water discharged from the cistern into the urinal, this water
charging a syphon fixed in the cup causes the cup to be emptied and thus relieving
it of the weight of water and urine allows the cistern to resume its condition ready
for next use.
(2) A supply cock to the cistern which is closed by a weight on a lever, and not
by a float, but is opened by the weight of a float acting on a second lever, and this
cock can be used with peculiar advantage in all kinds of cisterns.

page_text: Wе, THOMAS HOLT and JAMES HOLT both of Back Oxford Street, Liverpool in
the county of Lancaster, Plambers, 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 :-
The object of our present invention is to provide improved cisterns for flushing
urinals, the flushing being actuated automatically by means of the weight of the urine
discharged into the urinal.
We construct such cisterns as follows:-
We provide a cistern of the tilting, non-tilting, syphon, or non-syphon kind and
we place in the vertical part of the waste pipe of the urinal or in a pipe connected
therewith a cup or receiver which is suspended from the end of a lever pivoted close
to the cistern. This lever is counter-balanced and connected with the cistern as
herein-after described so that when the end of the lever from which the cup or receiver
is suspended, is depressed by the weight of urine caught in the cup, the contents of
the cistern are automatically discharged into the urinal basin.
We provide means for emptying the cup or receiver after it has pulled down the
lever and the flush is completed, so that the cistern can then resume its normal
condition ready for future use. For this purpose we prefer to fix within the said cup
or receiver a small syphon so that when the cup is filled by the water flushing the
waste pipe, the syphon becomes charged and so empties the cups; or the cup or
receiver may be arranged so that when filled it will tilt and empty and then return to
its normal position.
The supply cock of the cistern is operated by a double ended lever, and the float
is hooked over one end of this lever in such a way that when the float descends below
its normal level it pulls its end of the lever down, but when it rises it releases and
cannot push this end of the lever up. The other end of the double ended lever has a
weight secured to it sufficiently heavy to resist the pressure of water and close the
supply cock as the float rises. In this way the descent of the float opens the supply
cock, and the force which keeps the cock closed is constant when the float is at or
above its normal level.
Our improvements are specially applicable to tilting syphon cisterns such as are set
forth in our Patent No. 4496 of 1886 and in order that our invention may be more
fully understood reference is made to the accompanying drawings in which Figs. 1, 2,
and 3 show our improvements fitted to such a cistern. In Fig. 4 the cistern is of
the non-tilting non-syphon type.
Referring to the first form of cistern, Fig. 1 is a side elevation the supply cock
and its attachments being omitted, the cup or receiver and part of the flushing pipe
being in section.
Fig. 2 is a side elevation the cup or receiver and tilting gear being omitted and the
frame surrounding the cistern being in section.
Fig. 3 is a section on A A of Fig. 2 showing the connection between the float and
the supply cock lever. Throughout the drawings similar parts are denoted by similar
reference figures, and the direction in which the section is viewed is indicated by
the small arrows adjacent to the letters denoting the plane of section.

page_text: 1 is the cistern slung on the pivots 2 which are carried on brackets not shown
fixed to the frame 3 surrounding the cistern.
The general construction of this cistern 1 is similar to that set forth in our.
Patent No. 4496 of 1886 that is to say the cistern is provided with a syphon 4 whose
bend stands above the water level in the cistern when in the position shown and
stands below the said water level when the cistern is tilted in order to discharge its
contents; and the cistern is closed by a cover with a vertical rim and with an opening
with a vertical rim for the float 5 and a second opening or port at the rising end for
the admission of the water supply.
The position of the pivot 2 is however such that when the cistern is filled to its
proper level it tends to tilt with the syphon end downwards and when discharged it
tends to resume the horizontal position resting against the stop 33. 6 is the supply
cock operated by the double-ended lever 7-8. To the end 7 the weight 9 is secured
and the float 5 acts upon the end 8 by means of the hook 10 rigidly attached to the
float.
The weight of the float together with the pressure of the water in the supply cock 6
is sufficient to depress the end 8 of the lever as the float descends so opening the
supply cock 6 and raising the weight 9.
The weight 9 is sufficiently heavy to close the cock 6 as the float rises.
By this
arrangement, as soon as the float rises clear of the lever 7-8, the cock is kept closed
by a determinate and uniform pressure. The float 5 is rigidly attached to the lever 11
which has a short arm 12 and is pivotted at 13 to the rising end of the cistern.
14 is a pawl suspended from the frame 3 by the pivot 15. Unless pushed aside
as shown in the drawing, by the arm 12 this pawl engages with the shoulder 16 of
the lever 11 and prevents the tilting of the cistern. The flushing pipe 17, a portion
of which is shown in Fig. 1, is led from the urinal basin, to the upper part of which
is connected the funnel 18 which receives the discharge from the syphon 4.
19 is a cup suspended from the lever 22 by the rod 21 in the vertical part of the
waste pipe or in a pipe connected therewith, below its junction with the flushing
pipe 17. 20 is a syphon fitted within the cup 19, its bend being below the level of
the top of the cup so that when the latter is filled the syphon will become charged
and empty the cup.
The lever 22 is pivotted on the pin 27 carried by a bracket from the frame
and
is provided with the weight 28 and the pawls 23 and 24 which are pivotted to the
lever.
These pawls cannot descend relatively to the lever lower than the position shown,
but can lift freely.
The weight of 28 is such that when the cup 19 is empty the lever 22 rests in the
position shown but when the cup is filled or partially filled the latter preponderates
and pulls its end of the lever down. 29 is an are rigidly fixed to the side of the
cistern and having a detent 25 engaging with the pawl 24 and a second detent 26
engaging with the pawl 23.
The action of the cistern is as follows.
The cistern being filled to its normal level, the float will be sufficiently high to
have disengaged the pawl 14 from the shoulder 16, and as the cistern when full tends
to tilt with the syphon end downwards, the cistern will be prevented from tilting by
the detent 25 engaging with the pawl 24. Upon urine being discharged into the
urinal the cup 19 becomes partially filled and draws down the lever 22 so. disengaging
the pawl 24 from the detent 25 and allowing the cistern to tilt and discharge its
contents. As soon as the cistern tilts the pawl 23 engages with the detent 26 and
holds the cistern in position until fully discharged.
In the meantime the flush through the waste pipe will have filled the cup 19, and
as soon as the flush is completed the cup will begin to empty. When empty the
weight 28 will preponderate and disengage the pawl 23 from the detent 26 and so
allow the cistern to resume the horizontal position, in which position it will be held by
the pawl 14 engaging with the shoulder 16 until the cistern is charged when the rising
of the float will disengage the pawl 14 and the cistern will tilt slightly until caught

page_text: by the detent 25 engaging with the pawl 24. The cistern is now ready for future
use.
In Fig. which shows our improvements applied to a non-tilting, non-syphon
cistern, 1 is the cistern, 5 is the float, 6 the supply cock, 30 and 32 the discharge
valves and 31 the lever for operating the same, all of the usual construction.
The flushing pipe 17 is led from the urinal basin, to the upper part of which is
connected the valve 32 and as before the pipe 17 enters the waste pipe at a higher
level than the cup 19 which is suspended therein or in a pipe connected with the
waste pipe.
The cup 19 with its syphon 20 is similar to that already described and is suspended
from the lever 31 by the rod 21. The action of this form of cistern is as follows:
The cistern being charged and urine being discharged into the urinal the weight
of the urine caught in the cup 19 will pull down the lever 31 and so discharge that
part of the cistern in which the valve 32 is placed.
As soon as the flush is completed the cup 19 will in the manner already described
begin to empty, the lever 31 will resume the position shown in the drawing and as
soon as the cistern is charged it will be ready for future use.
We are aware that prior to our present invention supply cocks for cisterns have been
known in which the cock was opened by the descent of a float, and closed on the
ascent of the float by a weight acting on a lever and we make no claim to cocks so
operated.
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 cistern for flushing urinals actuated automatically by the weight of urine
caught in a cup or receiver suspended in the urinal waste pipe or in a pipe con-
nected therewith; substantially as set forth.
2. A cistern for flushing urinals actuated automatically by the weight of urine
caught in a cup suspended in the urinal waste pipe or in a pipe connected therewith,
the said cup being fitted with a syphon by which it is emptied on the completion of
the flush, substantially as set forth.
3. A tilting syphon cistern for flushing urinals which is automatically caused to
tilt and so discharge by the weight of urine caught in a cup fitted with a syphon
and suspended in the urinal waste pipe or in a pipe connected therewith, the said
cup operating a lever which releases the cistern; substantially as set forth.
4. In tilting cisterns for flushing urinals a pawl for preventing the tilting of the
cistern unless fully charged, the said pawl being disengaged from the cistern by the
ascent of the supply cock float as the cistern becomes charged, substantially as set
forth.
5. In tilting cisterns for flushing urinals a lever 22, from one end of which a cup
or receiver 19 is suspended in the urinal waste pipe, or in a pipe connected therewith;
the said lever being counter-balanced by a weight 28 and being fitted with the
pawls 23 and 24 engaging respectively with the detents 26 and 25 fixed to the
cistern, substantially as and for the purpose described, and illustrated in Fig. 1.
6. The combination and arrangement of parts forming the improved cistern for
flushing urinals, substantially as described and illustrated in Figs. 1-2 and 3.
7. The combination and arrangement of parts forming the improved cistern for
flushing urinals substantially as described and illustrated in Fig. 4.
