Improvements in Tipping Tanks for Water Closets.
We, J. DUCKETT AND SON LIMITED, of Sanitary Ware Works, Burnley, in the
County of Lancaster, ALFLED DUCKETT, of Fern Royd, Burnley aforesaid,
Sanitary Ware Manufacturers, FRED SMITH BUTTON, of Inglewood, Burnley
aforesaid, Civil Engineer, and JOHN WHITAKER BULLOCK, of 30, Accrington
Road, Burnley aforesaid, Manager of Sanitary Ware Works, do hereby declare
the nature of this invention to be as follows:-
Our invention relates to the construction of rubber buffers, and their fittings
for automatic tippers, and relates more particularly to that class of buffers,
which are placed at the back of the tipper box, and between it and the tipper,
the latter being impeded in either direction by two lips, which come against the
buffer in its tipping or return movement. Our object is to make these fittings
more durable, and to render them less expensive in renewals.
The buffers instead of being fixed on their rods or axles are loosely mounted
thereon, in such a manner that as the tipper tilts, a small projection thereon
will bear slightly against the rubber buffer, and cause it to revolve somewhat,
previous to tipper being finally stopped by the lip near the bottom, whereby
the sudden rebound and chock of tipper is lessened, noise is diminished, and
there is not the same wear and tear of the parts. To shew clearly how we
accomplish this we will refer to the annexed drawings. Figs. 1 and 2 are
detached sectional plan view and elevation respectively of the tipper box and tipper
furnished with and fittings in accordance with our invention. A is the rubber
buffer, B the axle, upon which is loosely mounted the said buffer A, so that
when the tipper G tilts, a projection at C touches buffer A slightly and makes
the latter revolve a little. When lip D finally strikes rubber A on tilting of
tipper G, it acts in the ordinary manner as a stopper, but is prevented from
striking the buffer A always in the same place.
Fig. 1 gives a sectional plan of the buffer A loosely mounted on its axle B,
whose end is made flat at W, and fitted to tipper box or container H by studs J
secured by nuts (see Fig. 1).

by reference to Fig. 3. His a vertical section of the back of container, through

Improvements in Tipping Tanks for Water Closets.
We, J. DUCKETT AND SON, LIMITED, of Sanitary Ware Works, Burnley, in the
County of Lancaster, ALFRED DUCKETT, of Fern Royd, Burnley aforesaid,
Sanitary Ware Manufacturer, FRED SMITH BUTTON, of Inglewood, Burnley
aforesaid, Civil Engineer, and JOHN WHITAKER BULLOCK, of 30, Accrington
Road, Burnley aforesaid, Manager of Sanitary Ware Works, 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 state-
ment;
:
Our invention relates to improvements in the construction of rubber buffers
and their fittings for automatic tippers, and relates more particularly to that
class of buffers, which are placed at the back of the tipper-box, and between
it and the tipper, the latter being impeded in either direction by two lips, which
come against the buffer in its tipping or return movement. Our object is to
make these fittings more durable, and to render them less expensive in renewals.
The buffers instead of being fixed on their rods or axles are loosely mounted
thereon in such a manner that as the tipper tilts, a small projection on the
latter will bear slightly against the rubber buffer, and cause it to revolve some-
what, previous to the tipper being finally stopped by the lip near the bottom,
whereby the sudden chock or rebound of tipper is lessened, noise is diminished,
and there is not the same wear and tear of the parts.
To shew clearly how we accomplish this, we refer to the drawings annexed
to our Provisional Specification, in which Figs. 1 and 2 are detached sectional
plan view and elevation respectively of the tipper box and tipper, furnished with
buffer and fittings in accordance with our invention.
A is the rubber buffer, B the axle, upon which is loosely mounted the said
buffer A, so that when the tipper G tilts, a projection at C touches buffer A.
slightly, and makes the latter revolve a little. When tipper D finally strikes
rubber A on tilting of tipper G, it acts in the ordinary manner as a stopper,
but is prevented from striking the buffer A always in the same place. To
prevent lateral displacement of the loosely mounted buffer A, the tipper-box and
tipper, or either of them are formed with recesses or grooves as shewn to prevent
buffer leaving its position.
Fig. 1 gives a sectional plan of the buffer A loosely mounted on its axle B,
whose end is made flat at W, and fitted to the tipper box or container H by
studs J secured by nuts (see Fig. 1). As seen in this view, the loosely mounted
buffer A is prevented from moving laterally by a channel or groove formed in
the tipper box and tipper respectively.
Our method of fixing the axle B to the studs J will be clearly understood by
reference to Fig. 3. H is a vertical section of the back of container, through a

page_text: hole in which is passed bifurcated stud J, which is firmly secured to the container
by a nut K. The flat end of axle B is inserted between the bifurcations of
stud J, and a pin F is then passed through holes E formed in the said stud J,
and also through a hole in the axle B, whereby the axle is firmly held in
position.
In another way, the flat end of axle B and the hole through it may be dis-
pensed with, the axle being held in position by a set screw fixed in stud J.
By these arrangements, the durability of rubber buffer A is greatly increased.
Rubbers for this purpose are usually made fast upon their axles, which causes
them to wear by concussion in one place only, and they soon become inoperative
and require renewing. We fix an aluminium lining, or a lining of other suit-
able non-corrosive metal or material to rubber buffer A to protect it from
corrosion and wear caused by contact with buffer rod B.
It is manifest, that by these arrangements, rubbers can be made much more
durable than hitherto, and be readily renewed when necessary.
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 arrangement of buffers of automatic tippers for water
closets, and the improved construction of such tippers, substantially as and for
the purpose herein before described and illustrated.
2. Lining rubber buffers of automatic tippers with aluminium or other suit-
able non-corrosive metal or material, substantially as and for the purpose
described.
