Founders and Finishers and Sanitary Engineers of Halifax in the County of
York "IMPROVEMENTS IN THE MANUFACTURE OF METAL CISTERNS AND SYPHONS
USED THEREWITH AND IN APPARATUS EMPLOYED IN SUCH MANUFACTURE,"
This Invention relates to the class of cisterns mainly used with water closets
and constructed of sheet metal the parts composing the whole being secured to
each other by soldering many of such cisterns being divided by a partition forming
two water containing compartments.
The object of this my invention is by the use of improved apparatus for folding
and shaping the parts to facilitate the soldering and to construct a better and
stronger cistern with less expenditure of time and labour.
Apparatus for purpose aforesaid according to this my invention for the con-
struction of a double or partition cistern consists of two metal blocks of form
similar to the interior compartments of the cistern, the blocks rest upon a platform
and the latter is mounted upon a shaft carried by side or end frames so that
the platform and blocks may readily be turned or partially revolved for purpose
hereafter explained.
In constructing a double cistern I employ a sheet of lead of length and width
sufficient to form the sides bottom and partition, this I fold or double from the
middle of its length and introduce the folded part between the two blocks where
it is held by the wedging or closing of the two blocks, the remaining portion of the
sheet is now divided one portion spreading over the right hand block the other

bottom outsides also the side flanges of the cistern the portion between the
moulds forming the partition near the outer edges of bottom and sides of each end
of each block is a groove or recess into which the overhanging metal is chased or
pressed and on the end pieces of metal being placed in position a portion thereof
is closed or blocked into the said groove the two layers of metal forming a beading

For the purpose of securing a certain amount of over-lap at each end of the
blocks a guage plate is placed against the end of the block and the lead is cut or
pared off evenly with the face of the said plate.
The blocks and its plate are mounted upon an axis as described in order to
facilitate the turning over the blocks and plate so as to facilitate operations at
the ends of the blocks a counter balancing weight is applied to the underside
of the bed plate for facilitating turning over or rotating the apparatus and holding
or locking pins wedges or other like devices are employed for securing the apparatus
in position when its upper surfaces or its ends are being used.
In manufacture of a cistern having no partition one block having end grooves
as and for purpose aforesaid is employed.

Founders and Finishers and Sanitary Engineers of Halifax in the County of
IMPROVEMENTS IN THE MANUFACTURE OF METAL CISTERNS AND SYPHONS
USED THEREWITH AND IN APPARATUS EMPLOYED IN SUCH MANUFACTURE
York
This invention relates to the class of cisterns mainly used in connection with
water closets, and constructed of sheet metal the parts composing the whole being
secured to each other by soldering, many of such cisterns, being divided by a
partition forming two water containing compartments.
The object of this my invention is by the use of improved apparatus, for folding
and shaping the parts, to facilitate the soldering, and to construct a better and
stronger cistern with less expenditure of time and labour. Apparatus for purpose
aforesaid according to this my invention, for the construction of a double or
partition cistern, consists of two blocks, by preference of metal, of form similar
to the interior compartments of a double cistern, the blocks rest upon a platform,
and the latter is mounted upon a shaft, carried by side or end frames, so that the
platform, and blocks, may readily be turned or partially revolved, for purpose
hereinafter explained.
In constructing a double cistern, I employ a sheet of lead of length and width
sufficient to form the sides, bottom and partition, this I fold or double from the
middle, of its length, and introduce the folded part between the two blocks, where
it is held and nipped by the wedging or closing together of the two blocks, the
remaining portion of the sheet is now divided, one portion spreading over the
right hand block, the other over the left hand block, upon which the metal is
beaten or pressed, forming the bottom, outsides, also the side flanges of the cistern,
the portion between the moulds, forming the partition, near the outer edges of
bottom and sides of each end, of each block is a groove or recess, into which the
overhanging metal is chased or pressed, and on the end pieces of metal being
placed in position, a portion thereof is chased or blocked, into the said groove, the
two layers of metal forming a beading, inside the cistern, the joint so formed is
then secured by soldering, burning or fusing the joints, so made and soldered, or
fused, are at the outside of the cistern, and the solder is not exposed to the action
of the water or contents of the cistern-For the purpose of securing an exact
amount of overlap, at each end of the blocks, a guage plate is placed against the
end of the block, and the lead is cut or pared off evenly with the face of the said
plate-The blocks and its plate are mounted upon an axis, as described in order
to facilitate, the turning over the blocks, and plate so as to facilitate operations at
the ends of the blocks, a counterbalancing weight is applied to the underside of
the bed plate, for facilitating turning over, or rotating the apparatus and holding
or locking pins wedges or other like devices, are employed for securing the
apparatus in position, when its upper surfaces, or its ends are being used..
In manufacture of a cistern having no partition, one block having end grooves
as and for purpose aforesaid is employed-Syphons, I construct or cast in one
piece having divisional midfeather (instead of separate legs) for the water and air
or relief pipe.
Such being the nature and object of this my said invention I will now proceed
to describe the same in detail, and in order that the invention may be fully

DESCRIPTION OF THE DRAWINGS.
Fig: 1 is a side elevation of improved apparatus, employed in the manufacture
of metal cisterns-Fig. 2 is an end elevation-Fig: 3 is a plan view-Figs 4. 5. 6.
7.8 are details-Figs 9. 10. 11 shews elevation section and plan of improved
syphon, with air or relief pipe.
At 1. 2. are two metal blocks, of form similar to the interior compartments of
a double cistern, the blocks rest upon the platform 3, mounted on the shaft 4,
having steadying pin 4, the lugs 4b, and pin also serve to hold blocks and
platform 3 steady, carried by the side or end frame 5, 6, at 7 is a counterbalancing
weight, adjustable.on. the lever or arm 8, so that the blocks and platform, may
readily be swung or radiated, on the shaft 4, bringing the ends of the blocks, from
a, vertical to a horizontal position, and facilitating labour of the operator, as
hereinafter described-At 9.is shewn groove or channel cut or sunk around the
outer line, at the ends of each block, or such groove may be at the sides of the
block or blocks: The use of the apparatus and manufacture of a cistern having
midfeather or divisional. plate, and two compartments, is as follows-A sheet of
lead of length and width sufficient-to-form the sides-bottom and partition, is
folded into equal lengths, as shewn at 10 Fig. 4, its folded end 11, is passed into
and to the bottom of the space. 12, hetween the two blocks 1. 2. the latter are then
by means of the wedge or pins 15. 16 forced together, so as to nip and firmly hold
the portion of lend between them, whereon.the projecting part of the lead 13. 14
is divided, one portion being spread over the right hand block, the other portion
over the block to the left hand, the metal being beaten or pressed closely to the
blocks and to its flanges 17. 18, the blocks are now turned on the shaft 4 so as
to bring their ends into the horizontal position, a guage plate 19 of form corre-
aponding to the end of each block, and of thickness sufficient to leave the necessary
quantity of lead overlapping, is placed against the ends of each block, and the
superfluous or spare lead overhanging the face of the guage plate, is by a knife or
other cutting tool, cut away, so that on the. guage plate being removed there is
the exact quantity of lead projecting and overhanging, the ends of each block,
as will suffice for filling the groove 9, the overhanging lead being beaten or drifted
into the grooves by a chasing block or tool-a sheet of lead corresponding in form
to the guage plate, or to the end of each block is cut and placed on the end of the.
block, and its outer edges chased into the grooves 9, the lead in the grooves is then
burnt or soldered, as is also the composing the flanges, which has been in like
manner chased into the grooves 20, is burnt or soldered as described. The wedge
pins 15. 16, are now removed, so that the blocks are loose, thereon the metal
forming the cistern is lifted, or dropped of the blocks-In the manufacture of a
cistern containing but one compartiment, a single block of the required size will
be used, or the two blocks will answer the purpose, the lead being passed over and
not between them, as when used for a partition cistern.
Having thus fully described the nature and particulars of this my said invention,
together with the manner in which the same is to be, or may be performed, or
carried into practical effect, I would have it understood that I claim as my
invention..
Firstly-The manufacture of cisterns having inner double lapped or beaded
joints as herein fully described.
Secondly The manufacture of cisterns, double, or partitioned, and having the
double lapped or beaded, joints, and as herein fully described.
Thirdly The use and employment of a block or blocks, having grooves formed
therein for purpose herein described.
