improvements in the Construction of Sheet Metal Cisterns.
1, WILLIAM PRIESTLEY BUTTERFIELD, of Otley Road, Charlestown, Baildon,
near Bradford, in the County of York, Cistern Manufacturer, do hereby declare
the nature of this invention to be as follows:-
This invention has for its object the construction of sheet plate cisterns of
iron, copper and other suitable material in such a manner that, the joints
connecting the plates are more readily formed and stronger than when constructed
in the manner as hitherto; and arranged so that when the cisterns are put
together, they are of true shape, and may be secured by soldering the joints or
immersing the entire cistern in a bath of galvanizing liquid.
In carrying out my invention I form the end and side plates for say a square
or oblong cistern with the top flanged inwards, that is, towards the interior of
the cistern, these flanges when the cistern is put together are secured at the
angles by rivets or the like, the side joints of the cistern are formed by bending
the plates that the edge of one plate interlaps into the folded edge of the adjacent
plate, such folds or laps being so formed that when put together they are in the
inside of cistern. The bottom plate of the cistern is folded so as to form a
channel all around same for the reception of the side plates, into which they
are inserted, the folds at the angles engaging with each other.
When the plates are put together they may be secured by soldering at the
joints, but if constructed of iron they may be secured together and a water tight
cistern formed either by solder or by dipping the cistern into a galvanizing
bath, the bath liquid filling up the spaces between the folds at the joinings.
By forming the joints in the manner described, there is a flange formed
around the bottom, leaving a cavity below the bottom plate, through the com-
bined side and bottom plates rivets may be passed, or the plates may be indented
at intervals on one side, thus raising the other side, or the combined plates may
be corrugated at the juncture, thus adding strength to the joint.
By bending the jointed edges of the plates in the manner described, the plates
can be packed into small space, thus facilitating the export of same, the joints
being of such form that cisterns are readily put together and secured in the
manner as before described.

I, WILLIAM PRIESTLEY BUTTERFIELD, of Otley Road, Charlestown, Baildon,
near Bradford, in the County of York, Cistern Manufacturer, 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:-.
This invention has for its object, the construction of sheet plate cisterns of
iron, copper, and other suitable material in such a manner that, the joints
connecting the respective plates together, are more readily formed and stronger
than when constructed in the manner as hitherto; and so arranged that, when the
cisterns are put together, they are of true shape, that is to say, the angles and
plates bear the proper and desired relationship to each other, and may be
permanently secured by soldering the joints or immersing the entire cistern in a
bath of galvanizing liquid.
In describing my invention in detail, reference is made to the accompanying
sheet of drawings in which,
Fig. 1, represents a rectangular cistern made in accordance with my invention.
Fig. 2, is a vertical section of cistern on line a, Ն.
Fig. 3, is a sectional plan through line c, d.
Fig. 4, an elevation of the bottom portion of a cistern with the bottom joint
constructed in a manner so as to resemble rivetting, and
Fig. 5, is a vertical sectional elevation of the same.
In carrying out my invention, I form the end and side plates A, for say a
quare or oblong cistern with the top of the plates flanged inwards at 13, that is,
towards the interior of the cistern as shown; when the cistern is put together,
these flanges B are secured at the angles by rivets or the like C. The vertical
side joints D, of the cistern are formed by bending the plates in a manner that
the edge of one plate interlaps into the folded edge of the adjacent plate as
shown at each angle at D, in sectional plan Fig. 3, such folds or laps being by
preference so formed that, when the side plates of the cistern are put together,
they are in the interior of the cistern.
The bottom plate E, of the cistern is folded at F so as to form a channel all
around same for the reception of the side plates A. Into the channel F, the
bottom edges of the side plates are inserted and may be held in a temporary
manner by soldering in places or by other convenient means.
When the side and bottom plates A, and E, are put together in the manner
described, they may be permanently held together by soldering at the joints,
or by preference the plates may be held together and a water tight cistern formed
by dipping the cistern into a galvanizing bath, the liquid forming the said
bath filling up the spaces between folded plates at the angles, thereby permanently
attaching the plates together and making a water tight cistern.
By forming the joint around the edge of the bottom plate E, in the manner
described, a flange is formed around the bottom of cistern leaving a cavity G.
under the bottom plate E, thus making provision by which, should it be desired
or necessary, rivets may be passed through the combined plates A and E along
the bottom of cistern; or if desired, the said plates may be indented at intervals
on one side as at H, thus raising the surface of the plate on the outside resembling
rivet heads as at H¹, the said indentations and raised heads H and H', are formed
by a screw, cam, hydraulic or other suitable press fitted with corresponding
dies.
By bending the edges of the plates in the manner described, the construction

page_text: of cisterns is facilitated, another advantage is derived and that is, the plates
after they are bent as shown and described in order to form the joints, can be
packed into small space, thereby facilitating the export of same by enabling
cisterns to be packed into little space, the joints as will be readily understood,
being of such form that they may be readily put together in the manner as before
described, thus making a cistern strong and water tight at the joints.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
-
A cistern composed of plates the joints of which are bent in a manner that
the edge of one plate engages with the edge of another plate substantially in
the manner as herein before described and shown by the accompanying drawings.
