PROVISIONAL SPECIFICATION.
Improvements in Whirlers used in the Manufacture of Sanitary
Pipes and the like.
We, ARTHUR SABINE and TIMOTHY SABINE, of The Vulcan Ironworks.
Swadlincote in the County of Derby, Engineers, do hereby declare the nature of
this invention to be as follows:-
When a sanitary pipe or other similar article is taken from the pipe machine
it is passed on to what is known in the trade as a whirler' where it is. fettled,
scratched and otherwise finished off. The ordinary whirler consists of a
horizontally revolving plate mounted on the top of a vertical shaft driven by
means of bevil gear from a horizontal shaft upon which are mounted fast and
loose pulleys. Considerable difficulty has hitherto been experienced in placing
the pipe centrally of the vertical shaft and also in placing and removing large
pipes on or from the said whirlers. Our invention is designed to overcome these
difficulties.
In carrying out our aforesaid invention we hinge to the ordinary bed plate of
the whirler a top plate upon which is secured, by means of pins passing through
slots therein, a plug or short spigot preferably made slightly taper, this plug
is arranged to come centrally with the vertical rod to which the bed plate of the
whirler is fixed.
When each pipe is brought to the whirler it has a drum inside it as described
in our Letters Patent No. 11650 of 1895, this drum is provided at its lower, end
with an internal flange and the aforesaid plug or short spigot fits centrally and
accurately inside this flange and thus ensures the pipe being perfectly central of
the whirler. The object of hingeing the top plate to the bed plate of the whirler
is to enable the head of the whirler to be tipped for convenience in placing large
pipes thereon.
We form a central hole in the hinged top plate to fit accurately over a corres-
ponding projection on the bed plate."
It will thus be seen that self centreing is absolutely ensured both for the hinged
top-plate and for placing the drum and pipe on the whirler.
Different plugs will of course be required for different sized pipes and drums,
and the said plugs may be fixed to the greatest nicety by means of slots in the
top plate..

Improvements in Whirlers used in the Manufacture of Sanitary
Pipes and the like.
We, ARTHUR SABINE and TIMOTHY SABINE of the Vulcan Iron 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:-
When a sanitary pipe or other similar article is taken from the pipe machine 5
it is passed on to what is known in the trade as a 'whirler' where it is 'fettled,'
scratched and otherwise finished off. The ordinary whirler consists of a
horizontally revolving plate mounted on the top of a vertical shaft driven by
means of bevil gear from a horizontal shaft upon which are mounted fast and
loose pulleys. Considerable difficulty has hitherto been experienced in placing
the pipe centrally of the vertical shaft and also in placing and removing large
pipes on or from the said whirlers. Our invention is designed to overcome these
difficulties.
In describing our said invention, reference will be had to the accompanying
sheet of Drawings upon which Figure 1 is a vertical section on line a a of
Figure 2 illustrating the application of our invention, and Figure 2 is a plan of
same on line 6 b of Figure 1 as will be hereinafter explained.
In carrying out our aforesaid invention we hinge to the bed plate A of the
whirler a top plate B upon which is secured, by means of pins J passing through
slots K therein, a plug or short spigot C preferably made slightly taper, this
plug is arranged to come centrally with the vertical rod D to which the bed
plate of the whirler is fixed.
When each pipe is brought to the whirler it has a drum E inside it as described
in our Letters, Patent No. 11650 of 1895, this drum is provided at its lower end
with an internal flange F and the aforesaid plug or short spigot C fits centrally
and accurately inside this flange and thus ensures the pipe being perfectly
central of the whirler. The object of hingeing the top plate B to the bed plate
of the whirler as shewn at L L is to enable the head of the whirler to be tipped
for convenience in placing large pipes thereon. Upon Figure 1 the top plate B
and plug C are shewn tipped right back by the dotted lines on the left side of
the figure, these parts are also shewn in this position by firm lines on Figure 2.
We form a central hole or recess G in the hinged top plate to fit accurately over
a corresponding projection H on the bed plate.
It will be seen that self centreing is absolutely ensured both for the hinged
top plate and for placing the drum and pipe on the whirler.
Different plugs will of course be required for different sized pipes and drums,
and the said plugs may be fixed to the greatest nicety by means of slots in the
top plate.
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:
In whirlers used for the manufacture of sanitary pipes and the like, the hinged
top plate B in combination with an adjustable plate and spigot C and means
such as shewn at G and H for placing the plate B centrally of the vertical shaft D,
substantially as and for the purposes described and illustrated.
