Improvements in the Manufacture and Construction of Automatic
Tipping Tanks and Receptacles for same for Flushing Water
Closets, Sewers, and the like.
We, JAMES DUCKETT AND SON LIMITED, of Burnley, in the County of
Lancaster, and JAMES DUCKETT of Woodleigh, Burnley aforesaid, 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 :-
The first part of our invention relates to improvements in the manufacture and
construction of the said tipping tanks, the object of which improvements is to
dispense with the usual buffers, increase the stability, reduce the liability to
fracture to a minimum, reduce the cost of construction and render the tippers more
reliable in action.
In carrying out this portion of our invention, the tipper is so formed or
constructed and centred that when nearly full of water, it will tilt and discharge
its contents with great force into the closet basin, drain or trap, but owing to its
peculiar shape, and the position of its axis, which is out of true centre, before the
tipper reaches the bottom of the tipper box, a reaction takes place due to gravity,
and the front portion of the tipper swings upwards, and assumes a position
perpendicular with the true centre or thereabouts, then falls back again, and
ultimately regains its horizontal or normal position. By this novel arrangement
and construction of the tipper, the usual buffers for impeding its movements are.
dispensed with.
Our invention also relates to improvements in the manufacture of the said
special form of tippers, whereby they may be cheaply, efficiently, and expeditiously
made.
The next part of our invention relates to the manufacture and construction of
tipper boxes, and consists in forming in one piece of earthenware, the tipper box
or receptacle for tipper, and the usual dish brick for receiving an iron grating or
the like to cover top of tipper.
In the accompanying drawings,
Fig. 1 is a longitudinal section of our improved form of tipper and tipper box,
and Fig. 2 is a perspective view of the tipper.
A is the tipper, which is irregular in shape, the front portion of which rises
abruptly upwards, and terminates in a mouth at the top, whilst the back portion
bulges outwards, so that when mounted on the axis B out of true centre, it will
counterbalance the weight of sink or surface water, which flows through the
grating C into the tipper, until nearly full of water, when the tipper suddenly
discharges its contents and thoroughly flushes the closet basin or trap. The
tipper, however, is so shaped and centred, that before it reaches the bottom of the
ipper box, a reaction takes place due to gravity, and the front portion of the tipper
wings upwards, and assumes a position D, shewn in dotted lines in Fig. 1, perpen-
dicular with the true centre or thereabouts, then falls back again, finally regaining
ts horizontal or original position. By this novel arrangement and construction of
ipper, we are enabled to dispense with the usual buffers to check the tipper in its
novement.
In Fig. 1 is also shewn the next portion of our invention consisting of the tipper-
ox E with a kind of preparation or dish brick F in one piece of earthenware for
eceiving iron grating or the like C to cover top of tipper box, instead of
onstructing them in two separate pieces as heretofore.
Where the depth of drain is required to be diminished, or otherwise when more

page_text: convenient, the height of the tipper-box is-lowered to the position shewn in dotted
lines at G. The tipper-box may in this instance be provided with a stop or buffer H
to limit the tipper A in its upward movement.
Referring to Fig. 3, our improved tipper may be made to taper as shewn at J J,
but in this case the axle would be removed a little lower than shewn in Figs. 1
and 2, and nearer the back of the tipper, or it would not tilt.
We are perfectly aware that automatic flushing tanks have hitherto been used
.without buffers, but such tanks have been in the form of revolvers, that is, have
made a complete revolution by the suitable application and disposition of weights.
Our improved tipper, as will be seen only makes about half a revolution, does not
revolve, and is of uniform thickness throughout, whilst dispensing with the extra
balancing weight, which has hitherto been placed at the back of both tilting and
revolving tanks. Our improved tipper may be readily converted into a revolver by
suitably disposing the pivots, and would not require any additional weight at the
back or elsewhere, but we prefer our improved tipper to the revolver, because the
latter possesses amongst other disadvantages, the liability in turning round to stand
bottom upwards, and then requires attention.
We will now proceed to describe the manner in which the manufacture of our
improved tippers may be cheaply, efficiently and expeditiously performed. We
use an ordinary sanitary pipe making machine (or some similar. machine) into
which we fit a suitable die, of such a shape that when the article is pressed through
the die in the same way as making sanitary pipes, it will be in the form of an
irregularly shaped pipe, as shewn in Fig. 4. After leaving the machine and when
the article is stiff enough, the part from K to L (Fig. 4) is cut away. These
tubes may be in long or short lengths and afterwards cut to the length required.
After this the ends may be made and attached by any of the well known means,
but we prefer to make the ends in the following manner, viz. :-To fit the said
sanitary pipe or other suitable machine with a die, which will readily make a
peculiar class of tube M (as seen in section in Fig. 5) with flat sides of any required
length. When the curved parts N are afterwards cut away from this tube, four
square or rectangular flat pieces O will be left. By aid of a suitable template
these square or rectangular pieces O can be cut or stamped to the size and shape
required to form the ends of the tipper, which may then be attached in the usual
manner.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. Automatic bufferless tipping or flushing tanks of the form and construction,
substantially as described and illustrated in Figs. 1, 2 and 3 for the purpose
Bet forth:
2. The combination of tipper, tipper-box and dish-brick or preparation for
grating, the two latter formed in one piece of earthenware, substantially as
described, and illustrated in Fig. 1.
3. The means or method of manufacturing our improved tippers, and revolving
flushing tanks, substantially as described, and illustrated in Figs. 4 and 5 for the
purpose specified.
