PROVISIONAL SPECIFICATION.
An Improved Drum for Use in the Manufacture of Earthenware
Pipes, Chimney Pots, and the like.
We, ARTHUR SABINE and TIMOTHY SABINE of Vulcan Works, Swadlincote
in the County of Derby, Engineers, do hereby declare the nature of this invention
to be as follows:-
:-
The object of our invention is to provide a more durable and efficient form of
drum for use in the manufacture of earthenware pipes, chimney pots and the like,
than those at present in use.
These drums have hitherto been generally made of wood with iron or other
hoops or internal rings, rubber has also been used in the formation thereof; but as
they are continually in contact with. damp clay goods it is evident that wood will
warp or twist, and rubber will give way when opposed to the surface of the
goods, and that these materials are therefore quite unfit for use in the formation
of such drums.
It should be stated that the said drums are used when carrying the pipes or the
like from the machine to the drying sheds and also for trueing the inside of the
said pipes or other similar goods. They are usually inserted in a pipe from
the spigot end and drawn out from the socket end, the act of drawing out the said
drum should leave the inside of the pipe perfectly round and clean.
In carrying out our invention we form our improved drum of a central tube or
cylinder of metal having removable or replaceable metal ends at the top and
bottom and a suitable handle at the top for carrying the same and for convenience
in withdrawing from the pipe. The central tube or cylinder is preferably made
slightly larger in diameter at the bottom than at the top and the bottom ring is
made again slightly larger than the bottom of the central cylinder, to finish the
pipe off perfectly as it is withdrawn therefrom; the top ring is made of a bevilled
form on its top edge so as to enter and pass through the pipe without obstruction
and with perfect ease, these two rings are provided with lips fitting inside the
central cylinder and with internally projecting flanges to strengthen them and also
to provide bearings for bolting the two ends and securing the whole together, rods
or bolts passing internally from one end of the drum to the other and being secured
with nuts to the top and bottom rings.
We may form our improved drum of any suitable metal but preferably of
copper, brass or of some suitable combination of same, or of other non-corrosive
metal.
Although we have herein mentioned our invention more particularly as applied
to the manufacture of sanitary pipes, it will be understood that it is also applicable
to the manufacture of chimney pots and other similar earthenware goods.

page_text: An Improved Drum for Use in the Manufacture of Earthenware
Pipes, Chimney Pots, and the like.
We, ARTHUR SABINE and TIMOTHY SABINE, of Vulcan Works, Swadlincote
in the County of Derby, 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 :-
The object of our invention is to provide a more durable and efficient form of
drum for use in the manufacture of earthenware pipes, chimneys pots and the like,
than those at present in use, and one in which the different parts are more easily
renewed.
These drums have hitherto been generally made of wood with iron or other
hoops or internal rings, rubber has also been used in the formation thereof; but as
they are continually in contact with damp clay goods it is evident that wood will
warp or twist, and rubber will give way when opposed to the surface of the goods,
and that these materials are therefore quite unfit for use in the formation of such
drums. It should be stated that the said drums are used when carrying the pipes
or the like from the machine to the drying sheds and also for trueing the inside of
the said pipes or other similar goods. A drum is usually inserted in a pipe from
the spigot end and drawn out from the socket end, the act of drawing out the said
drum should leave the inside of the pipe perfectly round and clean...
In describing our invention reference will be had to the different figures upon
the accompanying sheet of drawings:-
Figure 1 is a vertical section on line 'a'-'a' of Figure 2 shewing a drum
constructed according to our invention.
Figure 2 is a plan of same looking down from the top of it.

Figure 3 is a sectional plan on line 'b' of Figure 1.
In carrying out our invention we form our improved drum of a central tube or
cylinder A of metal having removeable or replaceable metal ends at the top and
bottom B and C respectively and a suitable handle D at the top for carrying the
same and for convenience in withdrawing from the pipe. The central tube or
cylinder is preferably made slightly larger in diameter at the bottom than at the
top and the bottom ring is made again slightly larger than the bottom of the
central cylinder, to finish the pipe off perfectly as it is withdrawn therefrom;
the top ring is made of a bevilled form on its top outer edge so as to enter and
pass through the pipe without obstruction and with perfect ease, these two rings
are provided with lips B and C respectively, fitting inside the central cylinder,
and with internally projecting flanges B2 and C² to strengthen them and also to
provide bearings for bolting the two ends and securing the whole together, rods or
bolts E passing internally from one end of the drum to the other and being secured
with nuts F to the top and bottom rings B and C.
The dotted lines G shew partly the position which would be occupied by a pipe
or the like.
An additional or central ring H may be introduced if desired in case of long
drums as sometimes used for rolling pipes upon a table or the like, the said ring
being brazed or otherwise secured to the cylinder A.
The hottom ring may be formed with a central downwardly projecting annular
portion C³ to fit inside the ring I which is generally used in the trade for carrying
the pipe or the like from the machine to the "fettling whirler " upon which the
pipe or the like is generally finished off. The internally projecting flanges or
rings being bored perfectly true fit on the mandrel of this fettling whirler and our
improved drum will thus enable the pipe to be placed centrally of the fettling

page_text: whirler every time, and when the pipe or the like is carried thence to be dried the.
drum is withdrawn from the pipe or the like and leaves it on the plate I.
We may form our improved drum of any suitable metal but preferably of
copper, brass or of some suitable combination of same, or of other non-corrosive
metal.
Although we have herein mentioned our invention more particularly as applied.
to the manufacture of sanitary pipes, it will be understood that it is also applicable
to the manufacture of chimney pots and other similar earthenware goods.
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 :-
The improved drum for use in the manufacture of earthenware drain pipes,.
chimney pots and the like, consisting of top and bottom rings bolted together and.
carrying between them a cylindrical tube, with handle attached, the said top and
bottom rings being provided with internally projecting flanges for strength and self
centreing purposes, and the different parts being removeable and replaceable when
worn, substantially as described and illustrated.
