COMPLETE SPECIFICATION.
Improvements in and relating to Automatic Flushing Apparatus
of Waste Water Closets.
We, GEORGE CLARKE, JOSEPH CLARKE, and MARK CLARKE, of Norden Fire Clay
Works, Rishton, in the County of Lancaster, Sanitary Ware Manufacturers, 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:-
Our invention has reference to an improved form or shape of tipper in combination
with a novel arrangement and adaptation of the buffers therefor, whereby we gain
many important and distinct advantages over the usual methods, which have been
devised for impeding the motion of the tipper. The invention appertains to that
class of buffer or buffers, which have been placed at the back of the tipper, and
between it and the tipper box. Hitherto, in these arrangements, the motion of
the tipper in either direction has been impeded by lips moulded on the tipper,
which come against the buffer or buffers either way, and so check the tipper in
its movement.
Now these lips being small are not only difficult to mould, but are apt to
become broken off during transit, or when in use. Our invention possesses the
additional advantage that the tipper works with comparative freedom and without
noise, and if the tipper-box should happen to be somewhat out of level in the
setting, the tipper will still perform its functions with certainty of action.
Our object is to so reconstruct the back of the tipper in shape, that such lips may
be dispensed with, and the back of the tipper depended upon for checking its motion
by coming against the buffers in either direction. We form the tipper with a
perfectly straight back instead of curved or sloping, as heretofore. The tipper is
brought to a forward position in the tipper box, so as to allow of the introduction of
the buffer or buffers at the back, and in order that there may be sufficient room for
the movement of the tipper, the front portion of the tipper-box from the top to the
outlet is curved considerably.
Our invention will be at once apparent from reference to the annexed drawing,
wherein A is the tipper-box, B the tipper, and C the buffer or buffers.
The tipper B is formed with a perfectly straight back D as shewn, and is brought
to a forward position in the tipper-box, so as to permit of the introduction of the
buffer or buffers C between it and the tipper box. We preferably employ two
buffers, which may be of the usual round rubber, mounted on a stud, one on each
side of the tipper-box, and secured by a nut; or a rod may extend from one side to
the other of the tipper-box, upon which the buffer or buffers may be placed; or the
buffer or buffers may be otherwise mounted.
The drawing illustrates the tipper in its normal position, its top portion being
checked by the buffer C. When the tipper tips, it assumes the position shewn in
dotted lines in the drawing, its bottom portion coming against the buffer. The
front portion of the tipper-box is increased in its curvature at E to allow free
movement of the tipper.

page_text: In a slight modification, certain portions of the back of the tipper may be formed
perfectly or nearly straight, while the other portions may be rounded during the
moulding to bring about the same result as we have already described.
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 :-
1. The improved shape or form and adaptation of tipper in combination with a
buffer or buffers placed at the back of the tipper-box for the purpose of impeding the
motion of the tipper in either direction, and so as to dispense with the formation of a
lip or lips on the tipper or the like, substantially as described and shewn in the
accompanying drawing.
2. The improved shape or form, adaptation and reconstruction of the tipper and
tipper-box in combination with a buffer or buffers placed at the back of the tipper-box
for arresting the movement of tipper in either direction, and so as to dispense with
the formation of a lip or lips on the tipper, substantially as described and
illustrated.
