Improvements in Water Cisterns for Use in Combination with
Closets, Washouts, Washdowns, and the like.
I, DAVID WILLIAM ALLMAN, of 281 Wilmslow Road, Fallowfield, Manchester,
in the County of Lancaster Plumber, do hereby declare the nature of this invention
to be as follows:-
This invention relates to water cisterns or tanks in combination with closets,
washouts, washdowns, and the like. The object of this invention is to economise
the water supply, by limiting the supply to the quantity of water that is necessary
for the purpose of cleansing places such as aforesaid.
The accompanying drawing shows a section of a water cistern with my invention
applied.
I construct a cistern such as a, that may hold any amount of water not exceeding
a quantity that is sufficient for the purpose of cleansing, each time a closet or like
place has been used.
I pass a flush pipe b up through the cistern, terminating within the cistern in a
syphon end c that is bell mouthed at d. The cistern is supplied from the water.
main e, the inlet f passing down into the cistern and the supply regulated by an
ordinary ball tap g.
I connect a branch pipe to the water main e and carry the end of said pipe in
a vertical position up to within a short distance of the bell mouth d of the syphon c.
I attach a nozzle to the upper end of said branch pipe, and a push or other
preferred form of tap k at the lower end of the aforesaid pipe h.
By these means when the tap k is pushed or otherwise operated, a jet of spray
is forced up the bell mouth d, carrying the water over the bend, when syphonic
action commences and is carried on until the quantity of water that is in the
cistern is emptied down the flush pipe b, when the cistern is refilled from the
water main in the ordinary manner. The overflow pipe is formed so that
the bell mouthed end is below the surface of the water in the tank.

COMPLETE SPECIFICATION.
Improvements in Water Oisterns for Use in Combination with
Closets, Washouts, Washdowns, and the like.
I, DAVID WILLIAM ALLMAN, of 281 Wilmslow Road, Fallowfield, Manchester,
in the County of Lancaster, Plumber, 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 water cisterns or tanks in combination with closets,
washouts, washdowns, and the like.
The object of this invention is to economise the water supply by limiting the
supply to the quantity of water that is necessary for the purpose of cleansing
places such as aforesaid.

page_text: I effect this object by the means hereinafter described, and as shown in the
accompanying sheet of drawings, in which
Figs. and 2 are sectional elevations of a water cistern with my invention
applied, and
Figs. 3 and 4 are details of my invention drawn to an enlarged scale.
In these views similar letters refer to similar parts.
In this invention I construct a cistern such as a that may hold an amount of
water that is sufficient for the purpose of cleansing each time a closet or like
place has been used: I pass a flush pipoo up through the cistern terminating
within the cistern in a syphon end c, that is bell mouthed at d. The cistern a is
supplied from the water main e the inlet passing down into the cistern, and the
supply regulated by an ordinary ball tap 9. I connect a branch pipe h to the
water maine and carry the end of said pipe in a vertical position up to within
a short distance of, or just within the bell mouth d of the syphon o as in Figs. 3
and 4. I attach a nozzle to the upper end of said branch pipe, and a push or
other preferred form of tap k at the lower end of the aforesaid pipe h¹.
By these means when the tap k is pushed or otherwise operated, a jet of water
or spray is forced up the bell-month d, carrying the water over the bend c', whether
placed in the position shown in Fig. 1, or as in Fig. 2, when syphonic action
commences, and is carried on until the quantity of water that is in the cistern is
emptied down the flush pipe b when the cistern is refilled from the water main e in
the ordinary manner.
In the application of my invention as shown in Fig. 1. an overflow pipe is not
necessary, as the water, if through accident or other cause except than by the
action of the nozzle.j, is caused to rise above the lower part of the bend c¹,
will flow down the flush pipe b.
The overflow pipe h as in Fig. 2, is formed so that the bell mouthed end lis
below the surface of the water when the water has reached the normal level in the
tank, and prevents cold air entering through said pipe.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. In water cisterns or tanks that are employed in combination with closets
washouts, washdowns, and the like, the use of a syphon that is caused to act by
means of an injection of water or spray into the mouth of said syphon, in the
manner and for the purpose substantially as herein before described, and as shown
in Figs. 3 and 4.
2nd. In water cisterns or tanks that are employed in connection with closets,
washouts, washdowns, and the like, the general arrangement of supply or service
pipes, in combination with a syphon that is actuated by means of a jet of water or
spray, in the manner and for the purpose substantially as herein before described.
3rd. The construction of the overflow pipe so that the inner end of said pipe is
placed below the normal level of the surface of the water in a tank such as a in
the manner and for the purpose substantially as herein before described.
Dated this 19th day of January 1894.
