1, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co. Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature of
this invention to be as follows:-
--
This invention relates to cases or receptacles for containing cement or other solid
or liquid substances.
Until recently cement and other pulverulent materials, for the purpose of preserving
and more especially for transporting the same have been enclosed in ordinary cases of
wood. These receptacles have several inconveniences, such as, for example, not being
tight, deteriorating rapidly, and constituting a casing which presents only an insignifi-
cant or no intrinsic value.
In the case or receptacle forming the subject of the said invention the above
mentioned inconveniences are obviated.
This improved case or receptacle is made of sheet steel or other suitable sheet metal
of a thickness adapted to the size and strength of the case or receptacle to be made.
A sheet is cut so as to correspond to the development of the body of the case or
receptacle and is then bent round at the two edges which are to be joined.
The said sheet is next placed in a rolling mill which is constructed in such a manner
that it will bend the sheet to the shape of a cylinder and form at the upper and lower
part of the latter a rebate of a width of about 5 or 6 millimeters.
The bent portion of the above-mentioned two edges is now opened a little and the
latter are caused to engage with each other so as to form a joint.
is brought to bear upon this joint in order to make it tight.
A strong pressure
Upon the aforesaid rebates are placed the heads, which are preferably made of wood,
and an iron ring is arranged upon each of these heads. The edges of the upper and
lower extremities of the sheet-metal cylinder are then bent round upon these rings.
In order to firmly secure the heads in their place upon the rebates, the edge can be
folded upon itself.
The external diameters of the outer portions of the cases or receptacles where the
said heads and rings are placed are preferably made equal to that of the middle
portion.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Metal Cases, Drums or
Receptacles for Cement and other Substances.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake and Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 relates to cases or receptacles for containing cement or any other
solid or liquid substances.
Until recently cement and other pulverulent materials, for the purpose of preserving
and more especially for transporting the same, have been enclosed in ordinary cases
of wood. These receptacles have several inconveniences, such as, for example not

insignificant or no intrinsic value.
In the case or receptacle forming the subject of the said invention the above-
mentioned inconveniences are obviated..
In the accompanying drawing,
Figure 1 represents the development of the sheet metal plate designed for the con-
struction of a case or receptacle, the edges being turned round at g.
Figure 2 is a section of this sheet metal plate, on the line X--Y.
Figure 3 represents the case or receptacle after it has been filled with cement for
example.
Figure 4 is a section on the line X' Y¹ of this case or receptacle.
Figure 5 represents the same case or receptacle, the plate being turned round at f
for consolidating the closing.
This improved case or receptacle is made of sheet steel or other suitable sheet metal
of a thickness adapted to the size and strength of the case or receptacle to be made.
A sheet is cut so as to correspond to the development of the body of the case or
receptacle and is then beur round at the two edges which are to be joined, as shown
in Figure 2.
The said sheet is next placed in a rolling mill which is constructed in such a manner
that it will bend the sheet to the shape of a cylinder and form at the upper and lower
part of the latter, ate and e', a rebate of a width of about 5 or 6 millimeters. The
bent portion of the above-mentioned two edges is now opened a little and the
latter are caused to engage with each other as shown in Figure 4 so as to form
a joint. A strong pressure is brought to bear upon this joint in order to make
it tight.
Upon the aforesaid rebates e and e¹ are placed the heads a and a¹ which are
preferably made of wood, and an iron ring or is arranged upon each of these
heads. The parts d and d¹ at the upper and lower extremities of the sheet-metal
cylinder are then bent round upon these rings, as shown at the lower part of the
case or receptacle, Figure 3. At the upper part this bending has not been
effected in order to represent the case or receptacle prior to this operation. In
order to firmly secure the heads in their place upon the rebates, the edge can be
folded upon itself, as shown in Figure 5.
The external diameters of the outer portions of the cases or receptacles where
the said heads a and a¹ and rings 6 and 6' are placed are preferably made equal
to that of the middle portion that is to say at X¹ Y¹.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by my
foreign Correspondent, I declare that what I claim is ;-
First. In a case or receptacle of sheet metal the union of the two parts of the
sheet through the medium of a joint formed of bent edges, as described and
represented in Figures 1, 2, 3 and 4.
Second. The formation of a rebate during the rolling of the sheet metal, for the
purpose of placing the heads of the case or receptacle, as described and repre-
sented in Figures 3 and 5.
Third. The employment, upon these heads, of iron rings firmly retained thereon
by the folded edges d and d¹ of the sheet metal as described and represented in
Figures 3 and 5.
Fourth. The consolidation of the heads of the barrel by folding upon itself the
part of the sheet metal designed for the rebate as shown in Figure 5.
Fifth. The forms of cases or receptacles of sheet steel or any other sheet metal,
as hereinbefore described and represented in Figures 3 and 5.
Dated this 19th day of November 1889.
