We, HERMANN ALBRECHT, of 60, Jennings Avenue, and JOHN R. BITNER, of 883,
Detroit Street, Cleveland, Ohio, United States of America, Manufacturers, 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 our invention is to provide a baling-press in which loose balable
material, and especially metal scrap, such as is produced in metal-stamping works,
may be pressed into a compact bale or ingot. The mechanism is especially contrived
with a view to making the press strong and durable, and to producing the desired
result quickly and with the least possible movement of the compressing mechanism.
The invention consists in the construction and combination of parts hereinafter
described and claimed.
In the drawings, Figure 1 is a side elevation of the press in its best form. Fig. 2
is a vertical sectional view on line 2-2 of Fig. 1. Fig. 3 is a sectional plan view on
line 3-3 of Fig. 1. Fig. 4 is a transverse section of the trough on line 4-4 of
Fig. 3.
Referring now the parts by letters, A represents a trough having front and rear
sides only, which rise from the bed-plate of the machine.
B B represent two compression-plates which fit in the trough and form the ends
thereof. These plates are movable in the trough toward and from each other for the
purpose of compressing the material confined between them in the trough. In
the machine as shown in the drawings these plates are secured to the ends of the
hydraulic rams D D¹, which are movable in the cylinders d d¹. These cylinders are
mounted on the bed of the machine at the ends of the trough. Two pipes d², d³
are connected to opposite ends of each cylinder, and these pipes are brought together
at a suitable point, and a valve or valves are provided whereby both pipes d² may be
connected at the same time with the pressure-pipe and the two other pipes d³ with
the exhaust, and vice versa. It is not thought necessary to make any specific
showing of the valves or the main pressure-pipe or exhaust-pipe. There is nothing
new about these specific parts of the device, and any suitable construction and
arrangement of such parts well known in the art may be adopted.
The top of the trough is closed during the compressing operation by a cover-
plate F. Any suitable cover-plate is included in the invention as broadly claimed,
provided it may be removed so as to permit the material to be baled to be placed in the
trough, and suitable mechanism is provided for holding it closed when the trough
has been charged. The particular construction illustrated has, however, certain
advantages over any other, as will appear in the subsequent description. In the
construction shown this plate is on the lower end of a hydraulic ram E, which is
movable in the vertical cylinder e. This cylinder may be supported in the necessary
relation to the trough in any suitable manner. As shown, it is secured to the plate H,
which is supported upon the four posts h which rise from the bed a. The
pipes el e connect the upper and lower ends, respectively, of this cylinder with the

page_text: pressure-pipe and exhaust, a suitable valve being provided for making the desired
connection.
An ejector-plunger G passes through the bottom of the trough. It is movable
in a hydraulic cylinder g which is fixed beneath the bed-plate. This cylinder,
like the others, is connected at opposite ends with the pressure-pipe and exhaust
by the pipes g¹ g², and a suitable valve is provided for making the desired
connection.
In operating the described mechanism the material to be baled may be charged
directly into the trough when the cover is lifted; but when this mode of operation
is adopted it is necessary for workmen to pack the material down as hard as possible
before the cover is closed. This takes time and adds to the cost, and, moveover, it
is impossible to get as much material into the trough for compression as by the
preferred mode of operation, as follows: A box I, two or three times as deep as
the trough, having neither top nor bottom, rests upon the floor or a platform
adjacent to the machine. The interior dimensions (length and width) of the box
are substantially the same as those of the trough when the compression-plates B B
are retracted, and only so much larger than the cover-plate as will permit this
cover-plate to move up and down through said box. The top edge of the trough is
set at the level of the floor or platform in order that the operation to be described
may be conducted most effectively. In the drawings the platform is shown to be
inclined from the floor-level to the level of the top of the trough.
The mode of operation is substantially as follows: As much material as it is desired
to compress is placed in the box I, the floor serving as the bottom of the box. The
box is then slid along the floor until it is directly over the trough and under the
cover-plate. To facilitate the accurate placing of this box, the top edges of the trough
and bottom of the box may be provided with tongues a5 and grooves i adapted to
engage with each other. When the box has been placed as described, the cover-
plate is caused to move down and it pushes the material out of the box and into the
trough, compressing it to about one-half to one-third of its bulk, more or less. Then
both plates B B are caused to move simultaneously toward each other, thereby still
further compressing said material between them. The cover-plate F is caused to
remain down during this compressing operation. The amount of compression is of
course dependent upon the extent of the movement of the plates B B and this may
be controlled by the valve provided for the purpose; but in the construction shown
there is little likelihood of anything breaking even if the movement of the plates
toward each other is not checked, because the hydraulic pressure on one plate-moving
ram is equal to the pressure on the other ram, and when the material has been
compressed as much as possible with the hydraulic pressure employed the movement
of the two plates ceases. Another advantage of using two inversely-moving pressure-
plates is that the desired result is effected more quickly, with less friction, and with
less strain upon the mechanism. After the bale has been formed the pressure-
plates B B are retracted, the cover plate is lifted, the box is removed, and the bale
Another box I has been filled in the meantime
is ejected by the ejector-plunger G.
and is ready, without loss of time, to be placed in position for another similar
operation.
We will now explain certain specific features of construction which, while of
On
considerable practical value and utility, are not material to the broad invention.
the sides of the trough and of the cylinders are the flange-ribs a³ ³, and through
these ribs pass the tie-rods K, by means of which the described parts are braced and
held in the described relation to each other.
At or near the lower edge of the cylinder e is a mutilated external flange e and the
socket h¹ in plate H, which receives the end of the cylinder, is provided on its upper
edge with a mutilated internal flange h². The lower end of the cylinder e is inserted
in the socket h¹ in the plate H and then turned upon its axis, thereby causing the
flanges h² and e* to interlock, and thus prevent the removal of the cylinder when in
the described position. A similar mutilated flange g' is formed upon the upper end
of the cylinder 9, and it interlocks in like manner with a mutilated flange at

page_text: on the bed a, surrounding the socket a³, which receives the end of said
cylinder.
The described construction makes an effective operative connection, but permits
the easy removal of either or both cylinders.
