PROVISIONAL SPECIFICATION.
Appliances for Flushing the Pans of Water-closets.
I, JOHN SHARPLES, of No. 3 Monk Street in the Borongh of Accrington,
Contractor, do hereby declare the nature of this invention to he as follows:-
With a view to the removal of excreta or other matter from closets where the
ordinary water supply is inadequate, I propose to utilise the waste slop or other waters,
which in domestic economy are usually discharged in a weak streum through a pipe of
limited area.
I employ a cistern, as nearly closed as possible, and capable of con-
taining several gallons, into which the waste is to be run. The cistern has an opening
of large area, through which its accumulated contents are at intervals to be emptied
by lifting a plug or valve which commands the opening. There is to be a communi-
cation with the pan or trapped vessel of the latrine which is assumed to be at a level
lower than the cistern. By these means an effective "flush" is obtained. The
cistern may be placed in any convenient position, preferably in one least exposed to
frost.

COMPLETE SPECIFICATION.
Appliances for Flushing the Pans of Water Closets.
I, JOHN SHARPLES, of No. 1, Monk Street, in the Borough of Accrington, in the
County of Lancaster, Contractor, 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 :-
With a view to the removal of excreta or other matter from closets, when the
ordinary water-supply is inadequate, I propose to use the waste slop or other waters
which, in domestic economy are usually discharged in a weak stream through a pipe of
limited area.
I employ a cistern as nearly closed as possible, and capable of holding
several gallons, into which the waste is to be run. The cistern has an outlet of
relatively large area, through which its accumulated contents are at intervals to be
emptied by lifting a plug or valve which commands the opening. There is to be a
communication with the pan or vessel of the latrine, which should be trapped, and
nust. be assumed to be at a level lower than the cistern. By these means an effective
"flush" is obtained. The cistern may be placed in any convenient position, preferably
in one that is little exposed to the action of frost.
The accompanying sheet of drawings, together with the explanatory description.
herein, are intended to represent my arrangement as it is in actual use. Corresponding
parts are indicated by similar letters of reference.
Fig. 1. is an elevation, mainly in section on an axial plane, the cistern and
most of its appendages being, in this case, circular in plan; (x) is a sink; (y) is
the floor level. The cistern (a) has a close-fitting cover (b) and an outlet (c)
commanded by a valve (d) which is moved vertically between guides (e) and is
lifted at intervals by the rod (f); this rod passes through a pipe (9), which is
fixed by a flanch to the cistern cover, and is continued upwards by a length of
soft pipe (h) cemented into its socket, and led to the sink outlet (1). The bore
of the pipe serves as a duct through which the cistern is filled; its lower end
limits the vertical movement of the valve, and forms a "trap" when in filling, the
liquid has passed it. The sink-grate acts as a guide for the upper end of the
valve-rod; a tube (5) communicates between the interior of the cistern and

page_text: the external atmosphere, thus permitting the escape of air as the cistern fills; its
outer end must be carried to a height exceeding that of the sink, and may be
bent downwards to prevent accidental stoppage. I use india-rubber or other
material to make tight the faces of the valve, flanch, and cover.
Fig. 2 respresents a modification of the apparatus, applicable when it is desired that
the lifting bandle should be clear of the sink. Here the main pipe is "breeched," one
limb being directed diagonally, and having a length of lead pipe leading to the sink-
outlet, as before; the other limb is carried vertically, clear of the sink, and high
enough to prevent its overflow.
A cistern of this kind may be used in close nighbourhood to the water-closet. In
that situation it would not be under constant observation; it would therefore be neces-
sary that it should be provided with an overflow outlet.
The cistern may be charged until the liquid fills the pipe (h) and floods the sink ;
or its contents may be run off at shorter intervals, and passed through ordinary
channels to the closet.
The above arrangements are such as have been found effective in practice, but 1 do
not limit my claim to the precise details herein described, since parts may be varied in
form and construction without departure from the general features; the valve for
example, may be of the "butterfly" or disc kind, opened or closed by partial
rotation.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
The employment of a cistern, fitted with a valve and other appurtenances substan-
tially as herein described, for the reception of waste waters which have been used for
domestic purposes, and for flushing the pans or vessels of water closets through its
agency.
