Complete Specification Left, 18th Dec., 1896-Accepted, 6th Feb., 1897
We, JOHN JOHNSTON GREEN and WILLIAM OATES, of the Firm of Oates
and Green, Limited, Claremount, Halifax, in the County of York, Sanitary
Engineers, do hereby declare the nature of this invention to be as follows:-
This invention has reference to water closets where tippers are employed and
emptied intermittently by waste water or otherwise. When these tippers have been
upset by the weight of water, they oscillate back again to their normal position
against a buffer or stoppiece. This buffer we now propose to make of a com-
bination of layers of wood and india rubber so as to prevent breakages and also to
lessen the wear and tear of the parts. We also propose to make that part of the
top edge of the tipper (which comes into contact with the buffer) wider or thicker
so as to give more bearing surface. The pipe connected to the bottom of the
tipper box, and which receives the waste water from the tipper, we propose to make
the mouth of the said pipe crescent shaped or somewhat in the form of the
letter D so that when the tipper is upset the enlarged mouth of the outlet pipe
more readily receives and concentrates the water consequently it is more quickly
delivered to the main.

Improvements connected with Waste Water Closets.
We, JOHN JOHNSTON GREEN and WILLIAM OATES, of the Firm of Oates
and Green, Limited, Claremount, Halifax, in the County of York, Sanitary
Engineers, 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 has reference to water closets where tippers are employed and
emptied intermittently by waster water or otherwise. When these tippers have
been upset by the weight of water they oscillate back again to their normal position
against a buffer or stop piece. This buffer we now propose to make of a com-
bination of layers of wood and india rubber so as to prevent breakages and also to
lessen the wear and tear of the parts.
We also propose to make that part of the top edge of the tipper (which
comes into contact with the buffer) wider or thicker so as to give more bearing
surface.
The pipe connected to the bottom of the tipper box and which receives the
waste water from the tipper we propose to make the mouth of the said pipe

page_text: crescent shaped or somewhat in the form of the letter D so that when the tipper is
upset the enlarged mouth of the outlet pipe more readily receives and concentrates
the water consequently it is more quickly delivered to the main.
In order to make our invention more clearly understood, we will refer to the
accompanying sheet of drawings illustrative thereof, wherein :-
Fig. 1 is section, and Fig. 2 plan, of a tipper and tipper box, having our
improved buffer or stop piece applied thereto.
Fig. 3 shews enlarged view of the buffer or stop piece and Figs. 4 and 5 plans
of the underneath part of same.
Referring to Figs. 1 and 2 letter A represents a tipper box and B a tipper
rocking on a pivot or fulcrum C. When the tipper has been upset by the weight
of the flushing waters emptied therei nto it rocks upon the pivot or fulcrum C and
when it has reached the required angle it comes into contact with the buffer or
stop piece D, and after discharging its supply of water oscillates back to its normal
position ready for another supply of water by its own weight.
To prevent breakage from violent concussion on the said tipper righting itself
we insert between the said buffer or stop piece D one or more layers of india
rubber E, which on the rebound of the tipper deadens or lessens the shock and
reduces the risk of breakage to a minimum.
In order to give more or greater bearing surface at the point where the edge of
the tipper strikes the buffer or stop piece, we form on the said tipper a shoulder or
thickening F, thereby doing away with the clipping of the edges of the tipper, as
is now the case.
Fig. 3 shews an enlarged view of the buffer or stop piece, the upper and lower
halves D, D', of which are held together by means of screws G.
Fig. 4 is a plan of underneath of part D shewing rubber E and screw holes H,
and Fig. 5 is a plan of underneath of part D'.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim, is :-
Firstly. In a waste water closet, the use of a tipper buffer, or stop piece,
composed of one or more layers of wood and india rubber substantially as described
and shewn in the drawings.
Secondly. In a tipper employed for flushing waste water closets, the use of a
shoulder such as F, for giving an increased bearing surface where the tipper
strikes the buffer or stop piece.
