PROVISIONAL SPECIFICATION.
Improvements in Means or Apparatus for Pressing or Consolidating
Quantities of Scrap Metal.
I ROBERT EVANS of Copper House Foundry, Landore, in the County of
Glamorgan, Iron Founder, do hereby declare the nature of this invention to be as
follows:-
The object of the invention is to provide means for expeditiously consolidating
quantities of scrap metal, preliminary to remelting, thereby to economise the space
occupied and waste incurred in the process.
For a moderate quantity operated upon suitable for remelting scrap metal produced
in producing plates for tinning and coating I arrange two or more cylindrical
receptacles, open top and bottom, connected by a metal web or framing to a vertical
hollow support which rests on a rotatory supporting base from which and through
the hollow support passes an axis or central rod. These cylindrical receptacles can be
swung on the central axial rod so as to come alternately or in turn, under a hopper
and over a closing platform or base piece, and then when from the hopper each has
received its quantum, it passes to beneath the head of a ram-which preferably is
actuated by hydraulic power-and over a closing part or a platform. Then the
ram head descending compresses the scrap and consolidates it into a ball or mass
suitable for the furnace operations. Delivery from the cylinders may be effected
by a movement of the ram in the absence of any closing bottom part, either
moving the ram to an increased stroke, or by withdrawal and interposing a dummy
or block.
The ram piston may be supported on columns or ties from the base to the head
one column being the centre rod or axis for the cylinders.
The cylinders may be rotated by levers engaged in sockets formed capstan fashion
in the base of the rotatory frame or by gearing or otherwise.
Partial compression may be effected by a ram operated by eccentric. or other means
whilst in line with the hopper and before passage to the ram,

page_text: Only one portion say half of the cylinders may rotate in the latter case the
scrap being pressed into half bulk, or one cylinder or cylinder in parts may do
double duty as the measure of quantity of scrap and as the cylinder into which the
piston is forced.
Delivery may be automatic by means of a falling or removable bottom.

COMPLETE SPECIFICATION.
Improvements in Means or Apparatus for Pressing or Consolidating
Quantities of Scrap Metal.
I ROBERT EVANS of Copper House Foundry, Landore, in the County of
Glamorgan, Iron Founder, 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 the invention is to provide means for expeditiously consolidating
quantities of scrap metal, preliminary to remelting, thereby to economise the space
occupied and waste incurred in the process.
For a moderate quantity operated upon suitable for remelting scrap metal,
produced in producing plates for tinning and coating, I arrange two or more
cylindrical receptacles, open top and bottom, connected by a metal web or framing to
a vertical hollow support, which rests on a rotatory supporting base, from which and
through the hollow support passes an axis or central rod. These cylindrical
receptacles can be swung on the central axial rod so as to come alternately or in
turn, under a hopper and over a closing platform or base piece, and then, when from
the hopper each has received it's quantum, it passes to beneath the head of a ram-
which preferably is actuated by hydraulic power-and over a closing part or a
platform. Then the ram-head descending compresses the scrap, and consolidates it
into a ball or mass suitable for the furnace operations. Delivery from the cylinders
may be effected by a movement of the ram, in the absence of any closing bottom part,
either moving the ram to an increased stroke, or by withdrawal, and interposing a
dummy or block.
The ram piston may be supported on columns or ties from the base to the head, one
column being the centre rod or axis for the cylinders.

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a vertical elevation, drawn to a small scale, of the whole apparatus.
Fig. 2 is a like view of the same drawn to a larger scale, the upper portion being
separated therefrom for convenience on the drawing.
Fig. 3 is a plan view.
a indicates the mass of scrap which has just been compressed by the descent of the
ram A, which works in the cylinder A¹, and which has been caused to descend by
the hydraulic pressure in that cylinder; B being the cap or head tied to the
foundation plate B by supporting columns B' B² B³. C is one of a pair of
cylindrical receptacles containing the scrap, now under operation. is the fellow
receptacle, now under the hopper E and being filled. D is the swinging base block,
capable of being swung by means of the handle D³, of the lever D, centred at D³,
on a bearing carried by one of the supporting pillars B¹. This block D serves to
close the bottom end of the receptacle C, or the end opposed the ram head. This
block rests on another ram A*, working in the cylinder A³, indicated by dotted lines,
and baving a short stroke, or stroke sufficient, when the block of scrap a has been
sufficiently compressed by the ram-head, to admit of the block D being released,
and the mass a ejected. This ejection may be effected with greater facility by a
further movement of the ram A. if desired. The return of the ram A may be effected
by means of the draw-back cylinder A2, here shown on top of the main ram.
F is a platform or bed, which serves to close the end of the receptacle being filled
with scrap from the hopper E, during that operation. The receptacles C. C', which
swing over the platform F, are connected by their web or frame C2, for which the
supporting pillar B forms the axis of rotation. The rotation of the receptacles C. C¹,
when the ram A is withdrawn, and the block D released by the withdrawal
of the supporting ram A' within its cylinder A³, may be effected by hand,
lever, or series of levers engaged in sockets, formed capstan fashion in the base of
the rotatory frame, or by screw or other gearing according to convenience.
Partial compression may be effected by a ram, operated by eccentric or other means,
whilst in line with the hopper and before passage to the ram A.
Only one portion, say half, of the cylinders may rotate in the latter case, the scrap
being pressed into half bulk, or one cylinder, or cylinder in parts may do double
duty as the measure of quantity of scrap, and as the cylinder into which the piston
is forced.
Delivery may be automatic by means of a falling or removable bottom.
A single receptacle or other number of receptacles may be arranged, but as a
general rule it will be found that two is a convenient number, one being filled whilst
the other is being operated upon. The direction of operation of the ram may of
course be varied.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
In apparatus for pressing or consolidating quantities of scrap metal preliminary to
remelting the combination or arrangement, operation and use of a ram or pressing
head, a receptacle or receptacles for, and means of filling, scrap, and a closing or
supporting block or part, with means of connecting and actuating the same, substantially
as set forth.
