IMPROVEMENTS IN HYDRAULIC PRESSES FOR BALING COTTON GOODS, OR OTHER MATERIALS
Year: 1884

page_text: We WILLIAM TURNER, Engineer and GILBERT LEWIS, Manager, both of the
Adelphi Street Works Salford in the County of Lancaster do hereby declare the
nature of said Invention for IMPROVEMENTS IN HYDRAULIC PRESSES FOR BALING
COTTON GOODS, OR OTHER MATERIALS to be as follows :—
Our invention relates to hydraulic presses for baling cotton goods or other
materials and is particularly applicable to the well known Ashcroft Cotton Baling
Press and the object of our Invention is to improve the construction of such
hydraulic presses so as to obtain greater power within a smaller compass, thus
avoiding the necessity of having very high presses.
To accomplish this, we propose to place the lower cross head below the press
bottom and to employ one or more false rams, preferably two; these false rams are
raised by steam power to give a preliminary pressure to the goods or materials.
The necessary hydraulic power is obtained through one or more cylinders, say,
four; the hydraulic rams are coupled to a strong cross head, through which the
false rams may pass when the false rams are raised above the ram cross head, they
are supported by suitable slides or catches jointed or secured to the cross head: at
this point the hydraulic ram or rams raise the ram cross head together with the
false rams and so give the final pressure to the bale. The return stroke of the
press is made by allowing the water to escape through a small back pressure
cylinder which may form a guide for the lower cross head. We propose to make
the pipe connections to the press with single connecting pipes and single regulating
valves and to make the let off or return water valves with one pressure valve; to
facilitate the opening of the valves, this is effected by first raising or relieving the
pressure valve which reduces the pressure and allows the other valve or valves to
be lifted by a bar or bars or in other convenient manner. We may make the box
in two parts, the upper part of which may revolve and the lower part of the box
may either be stationary or be traversed to and from the press on tram rails;

page_text: To prevent accidents and breakage of the press doors we propose to make
them entirely of cast steel, that is to say, the ordinary plates and bars are cast
together.
The nuts of the columns we propose to make of cast steel or other metal in two
pieces bolted together.

We WILLIAM TURNER, Engineer, and GILBERT LEWIS, Manager, both of the
Adelphi Street Works, Salford, in the County of Lancaster, do hereby declare the
nature of said Invention for IMPROVEMENTS IN HYDRAULIC PRESSES FOR BALING
COTTON GOODS OR OTHER MATERIALS, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Our invention relates to hydraulic presses for baling cotton goods or other

The return stroke of the press is made by allowing the water to escape through
a small back pressure cylinder which may form a guide for the lower crosshead.
We propose to make the pipe connections to the press with single connecting
pipes and single regulating valves and to make the let off or return water valves

the lower part of the box may either be stationary or be traversed to and from the
press on tram rails.
To prevent accidents and breakage of the press doors we propose to make

The nuts of the columns, that is to say, the inner nuts we propose to make of
cast steel or other metal, in two pieces bolted together.

And in order that our Invention may be fully understood and readily carried
into effect we will proceed to describe the accompanying three Sheets of Drawings,
reference being had to the figures and letters marked thereon.
Similar letters refer to similar parts throughout the several views,
Figure 1 is an elevation of an Ashcroft Cotton Baling Press to which parts of
our improvements are applied. Fig. 2 is a plan and Fig. 3 a side view showing the
arrangement of the crosshead and slides for supporting the false rams.
In these views, a is the top and a' the bottom of the press and b the boxes
which revolve round the column c: at the top of the press is the steam cylinder d,
the piston rod d of which is secured to a crosshead e which is connected by the
side rods f to the lower crosshead g near the bottom of the press; the two false
rams rest on and are secured at the lower end to the crosshead g and at the
upper end to the follower : the false rams h pass through the crosshead j to
which are coupled the four rams k of the hydraulic cylinders k¹; the catches or
slides are connected to the crosshead ; by the links : the small back pressure
cylinder m is secured to the press bottom a¹ at the upper end and the lower end passes
through and serves as a guide for the crosshead g; the ram m¹ of the cylinder m is
connected to the follower i.
Instead of securing the false rams h to the crosshead g and using the small
cylinder m as a guide we may connect the cylinder m to the crossbead g and
employ it to raise the false rams h.
When the piston d¹ by means of the rods fraises the crosshead g and the false
rams h are forced above the crosshead j to give the preliminary pressure to the bale
by means of the follower i, the slides are moved beneath the rams h to support
them consequently when the rams k of the hydraulic cylinders k¹ rise, they lift
both the crosshead ; and the false rams h and thus give the final pressure to the
bale in the box b. The return stroke of the rams is effected by the back pressure
cylinder m.

pumps n to each other and to the press by single pipes p and single regulating
It will be seen that these pumps are connected in pairs and with single
pipes to each pump.
valves o.
Fig. 5 is a section of one of the regulating valves o, in which o¹ is the suction
pipe; o the delivery valve and o³ the let off or relief valve.
Fig. 6 illustrates our improved method of opening the return water valves r
by a single pressure valve the valves are connected by the bar or crosshead 8:
the collar on the spindle of the valve r¹ does not come in contact with the bar s
to open the valves until the pressure in the pipes has been relieved.
Figs. 7 and 8 are detailed views of the improved inner nuts formed in two
halves bolted together; by employing these nuts the columns may be adjusted and
when the nuts are removed the columns may be drawn through without taking
down the press.
Figs. 9, 10, 11, and 12 are detailed views illustrating those parts of our improve-
ments which relate to the boxes of the press. The boxes are made in two parts,
the upper parts 61 revolving over a second or finishing press t, the lower box or
boxes b can be traversed to and from the press on tram rails u
Figs. 13 and 14 show a press door made according to our Invention, the plate v
and bars v of which are cast of steel in one piece.
