Improvements in the Method of and in the Machinery for the
Manufacture of Lead or Metallic Boxes and Plates for Electric
Accumulators, and other kinds of Lead or Metallic Boxes, Plates,
Tubes, Rods, and Strips of Irregular Section, or Plain, Ribbed,
Corrugated, or Fluted by Hydraulic Pressure.
I, ALEXANDER WYLIE, of Perseverance Iron Works, Johnstone, near
Glasgow, Engineer, do hereby declare the nature of my said invention to be as
follows:-
The first part of my invention consists in the construction of containers and
rams with suitable cores and dies, for hydraulic presses, such as are known, in the
lead trade, as lead pipe machines; and in the application of these containers, rams,
cores and dies, either to new lead pipe machines, or existing lead pipe machines;
and relates to containers having a cavity of rectangular or elliptic form, in which
cavity is inserted, by means of a suitable core seat, cores of a similar rectangular
or elliptic form, having the sides or surfaces smooth, ribbed, corrugated, fluted or
otherwise formed as may be required. The cavity in the container is filled with
lead, or metallic compound, filling the space between the sides of the container,
cavity and the core; which is by hydraulic pressure, forced upwards upon a ram or
plunger, and which is, at the point of cross section equivalent to the area of the
cavity in the container. In this ram or plunger is inserted a die of rectangular
or elliptic form, having an inside cavity, sinooth, ribbed, corrugated or fluted, in
a form similar to that described with respect to the core abovementioned; but
made somewhat larger, to admit of the escape from the container, over the whole
surface core and die, of the lead or metallic compound under pressure, in long
lengths, being internally the shape of the core, and externally the shape of the
cavity in the die as abovementioned; from which lengths it is cut up, and made
into boxes or plates as abovementioned.
The second part of my invention consists in the construction and application of
containers, rams and discs, as described in the first part of my invention, dispensing
with the core and contracting the cavity of the die, so that the lead or metallic
compound, when pressed against the rectangular or elliptic plunger with the dic,
as already described, may take the form of the cavity in the die, and be produced
smooth, ribbed, corrugated, or fluted strips, from which it is cut up into plates, or
used as rods and strips, as already described.
The third part of my invention consists in the construction of a container having
a cavity of rectangular or elliptic form, as already described in the first part of
my invention, but differing therefrom in having the sides of the cavity smooth,
ribbed, corrugated or fluted, and having a solid bottom, smooth, ribbed, corrugated
or fluted as required. Into this cavity a quantity of lead or other metallic
compound, equivalent in weight to the weight of the boxes desired to be produced,
is put.
This container is forced upwards, by hydraulic pressure, in the manner already
described, on a ram or plunger, which is made solid, the point of which is externally
smooth, ribbed, corrugated, or fluted, and equivalent in cross sectional area to the
inside of the boxes desired to be made. The lead or metallic compound is, by the
pressure exerted, forced to rise up on the sides of the cavity in the container, and
on the sides of the ram, filling the spaces between the point of the ram and the
sides of the cavity in the container forming the sides of the box, leaving a quantity

page_text: of lead or metallic compound in the bottom of the container cavity forming the
bottom of the box.

I, ALEXANDER WYLIE, of Perseverance Iron Works, Johnstone near Glasgow,
Engineer, do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The first part of my invention consists in the construction of containers and
rams, with suitable cores and dies for hydraulic presses, such as are known, in the
lead trade as lead pipe machines; and in the application of these containers, rams,
cores, and dies, either to new lead pipe machines, or existing lead pipe machines;
and relates to containers having a cavity of rectangular or elliptic form, in which
cavity is inserted, by means of a suitable core seat, cores of a similar rectangular
or elliptic form, having the sides or surfaces smooth, ribbed corrugated, fluted, or
otherwise formed, as may be required. The cavity in the container is filled with
lead, or metallic compound, filling the space between the sides of the container
cavity and the core; which is by hydraulic pressure, forced upwards upon a ram or
plunger, and which is, at the point of cross section equivalent to the area of the
cavity in the container. In this ram or plunger is inserted a die, of rectangular or
elliptic form, having an inside cavity smooth, ribbed, corrugated or fluted, in a
form similar to that described with respect to the core above mentioned; but made
somewhat larger, to admit of the escape from the container over the whole surface
of the core and die, of the lead or metallic compound under pressure, in long
lengths, being internally the shape of the core, and externally the shape of the
cavity in the die as above mentioned; from which lengths it is cut up, and made
into boxes or plates as above mentioned.
The second part of my invention consists in the construction and application of
containers, rams, and dies, as described in the first part of my invention, dispensing
with the core and contracting the cavity of the die, so that the lead or metallic
compound, when pressed against the rectangular or elliptic plunger with the die, as
already described, may take the form of the cavity in the die and be produced in
smooth, ribbed, corrugated, or fluted strips, from which it is cut up into plates, or
used as rods and strips, as already described.
The third part of my invention consists in the construction of a container
having a cavity of rectangular or elliptic form, as already described in the first
part of my invention, but differing therefrom in having the sides of the cavity
smooth, ribbed, corrugated or fluted, and having a solid bottom, smooth, ribbed,
corrugated or fluted, as required. Into this cavity a quantity of lead or other
metallic compound equivalent in weight to the weight of the boxes desired to be
produced, is put.
This container is forced upwards, by hydraulic pressure, in the manner already
described, on a ram or plunger, which is made solid, the point of which is externally
smooth, ribbed, corrugated, or fluted, and equivalent in cross sectional area to the
inside of the boxes desired to be made. The lead or metallic compound is, by the
pressure exerted, forced to rise up on the sides of the cavity in the container, and
on the sides of the ram, filling the spaces between the point of the ram and the

page_text: sides of the cavity in the container forming the sides of the box, leaving a quantity
of lead or metallic compound in the bottom of the container cavity forming the
bottom of the box.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings.
Fig. 1 is a vertical section, showing part of a lead press, water cylinder, piston,
and cross-head. A is a hollow plunger fixed to the cross-head, having a die B.
fitted thereto, as shown. This die may be constructed either with plain sides, or
corrugated or ribbed, to form the outside of the metallic box to the desired form.
D is the container for holding the metallic substance to be pressed into shape.
C is a core, which may be constructed either ribbed, corrugated or plain, so as to
impart the required shape to the inside of the box intended to be made.
Fig. 5 is a cross-section on the line ab of Fig. 1, showing one form of the hollow
plunger A and die B.
Fig. 6 is a cross-section, on the line c d of Fig. 1, showing the container D,
the hollow plunger A, and the core C, in position when operating on the
metal.
The space between the core C and the inner walls of the plunger A determines
the sectional form of the box, which is shown enlarged in Fig. 7.
Fig. 2 is a vertical section, illustrating another application of my invention in the
manufacture of plates of any sectional form. E is the hollow plunger fixed to the
cross-head. E is a die fitted to the plunger. This die may be constructed to form
metallic plates either ribbed, as shown in section in Fig. 9, or corrugated, or
smooth, as required. F is the container for holding the metallic substance to be
pressed into shape; the container being similar to that shown in Fig. 1.
Fig. 8 is a cross-section, on the line ef of Fig. 2, showing the form of the
plunger E and the die E', the spaces in the die determining the sectional form of
the plate to be produced.
Fig. 3 is a vertical section, illustrating another method of applying my invention
in the manufacture of corrugated or other boxes. G is a hollow or solid plunger
fixed to the cross-head, the end G¹ being shown corrugated. The sides H, of the
container I, are correspondingly corrugated, J is a loose core seat inserted in the
bottom of the container I. K is a small water piston fitted in a bore in the large
water piston, as shown. By means of hydraulic pressure the piston K is caused to
press the core seat J upwards, and thereby lift the box out of the container I,
finished.
when
Fig. 10 is a cross section of the container I, on the line g h of Fig. 3, showing the
end G of the ram G, and the finished metallic box m in position. The end of the
ram G¹, and the sides H, of the container I, may be corrugated (as shown) or
ribbed, or plain, as required.
For the purpose of forming the bottom to the box, the stroke of the lead press is
regulated to suit whatever thickness of bottom may be required. The container I
being pressed upwards by hydraulic pressure forces the metal against the plunger,
and, according to the travel of the water piston, any desired thickness can be left to
form the bottom.
my
