Improvements in Machinery for Compressing Iron or Metal
Scraps for the Manufacture of Bars therefrom.
I, JOSEPH BUTLER of 2 Greenfield Terrace, Pantyrheol, near Neath, in the County
of Glamorgan South Wales, Tin Plate Manufactory Manager do hereby declare the
nature of this invention to be as follows :-
The object of my invention is to provide machinery for compressing iron or metal
scraps, thick or thin, cold or otherwise, for the manufacture of bars therefrom.
According to my invention I make the walls of the press chamber or mould each of
a ram head each ram head being driven in opposite directions to its opposed head, by
screws or hydraulic power, each two of such heads are caused to approach one
another and to compress the metal scrap which is between same. The machine is
fed from one end, the other end ram being brought up into position to form one
wall, the opposite ram is then brought up against the metal to be compressed and
forms the opposite wall of the press chamber or mould; the same or similar action
takes place from the other side rams and the final pressure is applied from a ram
below. The block thus formed rests on the lower ram and is carried down with same
from the pressure chamber and is forced out through suitable apertures in the side by
levers or in any other suitable or convenient manner.

I, JOSEPH BUTLER of 2 Greenfield Terrace, Panty rheol, near Neath, in the County
of Glamorgan, South Wales, Tin Plate Manufactory Manager 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 :-
The object of my invention is to provide machinery for compressing iron or metal
scraps, thick or thin, cold or otherwise, for the manufacture of bars therefrom.
According to my invention I make the walls of the press chamber or mould each
of a ram head each ram head being driven in opposite directions to its opposed
head, by screws or hydraulic power and in such manner that by operating these
ramn heads each two of such heads are caused to approach one another and to
compress the metal scrap which is between same. The machine is fed from one end,
the other end ram being brought up into position to form one wall, the opposite
ram is then brought up against the metal to be compressed and forms the opposite
wall of the press chamber or mould, the same or similar action takes place from
the other side rams and the final pressure is applied from a ram below. When
pressure is caused to cease the block thus formed rests on the lower ram and is
carried down with same from the pressure chamber and is forced out through
suitable apertures in the side by levers or in any other suitable or convenient
manner.
In order to fully describe my invention I will now proceed to describe the same
with reference to the accompanying drawings.
Figure 1 is a longitudinal vertical section of a machine or press for compressing
iron or metal scraps according to my invention, Figure 2 is a plan of same partly in
section.
Similar letters of reference refer to like parts in both figures.
A A are the boxes in which the bundles of scraps or shearings to be compressed are
placed B1 B2 B3 B are the four ram or plunger heads which when brought into
position form the four side walls of the press chamber. B is the lower ram forming
the bottom of the press chamber D; E is the aperture through which (when the
ram B has been lowered) the compressed pieces or blocks are ejected; the ejecting
mechanism consisting, for example, of a sliding bolt Factuated by lever arm G
operated by hand lever H.
The iron or metallic scraps are placed in one or both of the receptacles A A and
they are driven into the press chamber D by the rams B1 B2, the ram B being in
the position shewn in the drawings. The motion of the rams B1 B2 may be effected
by hydraulic or other power, but in the machine illustrated in the accompanying
drawings, screws J J are shewn and which may be conveniently employed for the
purpose, these being actuated by power or double purchase gearing K and driven
by belt pulleys K' although hydraulic or other power as before stated may be used.

page_text: The rams B B2 are arrested in their motion at such a point as to allow of the next
pressing operation namely that of the two opposite side rams B³ B*; these are
applied preferably, and as shewn in the drawings, by hydraulic pressure, and still
further compress the enclosed scraps which are thus reduced to the correct width
desired; the final pressure is given to the mass by the lower ram B. When it is
desired to withdraw the compressed block from the press chamber, the ram head B
is lowered into the position shown by the dotted lines in Figure 1 and the block
resting thereon is carried down with it; the hand lever H is then thrown over by
the attendant and the sliding bolt F ejects the pressed block.
In some cases the ejecting levers may be so connected to one of the, say to one of
the side rams B1 B2, in such manner that the withdrawal of the latter may effect
the expelling of the block off the lowered surface of the rain head B automatically,
or the levers and automatic ejection may be dispensed with, and the block removed
by other suitable means.
The blocks may then be heated to welding heat and two or more of them placed in
the press chamber and subjected to second pressing process, but this or other pressing
actions are effected and the machine is caused to act in a similar manner to the
herein before described operation; or this second prossing process may be dispensed
with.
By machinery constructed according to my invention obtain a gradual com-
pression or solidification of scraps into blocks, such compression acting on nearly
every side of the block, there being direct acting pressures on five sides of same,
and these pressures not being sudden and abrupt, and taking effect, as they do,
from every side, the fibres of the metal are gradually interlocked, and the solidifi-
cation does not take place from one direction only, but from several.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. In compressing iron or metal scraps for the manufacture of bars therefrom, the
use and employment of machinery by which direct acting and effective pressure is
applied to five sides of the metal under treatment, producing a gradual interlocking
of the fibres and solidification on all sides of the block all substantially as herein set
forth.
2. In compressing iron or metal scraps for the manufacture of bars therefrom, the
construction and employment of machinery consisting of receiving channels or
boxes A A, of a press chamber essentially formed by rams B1 B2 B3 B* B³, operated
by hydraulic power, or by screws JJ, together with the arrangement of ejection
aperture E for the compressed blocks to be ejected, and means for ejecting same all
substantially as herein described with reference to the accompanying drawings.
