PROVISIONAL SPECIFICATION.
Improvements in Hydraulic Presses for Pressing, Bundling, or Baling
Cloth or other Textile Goods.
I, WILLIAM HUTCHINSON, of Weaste, Salford, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
In these presses as at present constructed there are two defects (a) the uprights
or standards are liable to wear loose and allow of a certain amount of play between
the base plate and the top plate (b) great difficulty is experienced when it is
desired to renew the cup leather packing, owing to the necessity of having to
remove the ram entirely. It is to obviate these defects that this invention
is designed.
It consists essentially in mounting the collar or shoulder of the standards or
uprights upon which the base of the press rests, upon foundation plates so placed
that all the weight of the press and the thrust comes directly upon the standards
and, in securing the cupped leather packing in position by a movable plate or
washer bolted or screwed tightly down upon it so as to enable it to be easily
removed or renewed without lifting the ram from the cylinder.
In carrying out the invention I construct the base and top plate in the usual
or any other convenient form with uprights or standards connecting the two
together. At the upper end of these standards are formed heads and at or near
the base are formed shoulders or collars. The standards pass through holes bored
or turned in the base plate and in the top plate and the heads and shoulders on the
standards respectively prevent any movement of the top and base plates. Beneath
the standards are fixed foundation plates upon which the ends of the standards
rest. The base plate is not supported other than by the collars of the standards
resting on the foundation plates. The foundation plates are fixed upon a bed of
masonry, concrete or the like to rigidly fix them.
The cylinder is mounted upon the base plate; a pipe passing through the latter
communicating with the pump. The cup leather packing is fitted into a groove
cut out of the top inner edge of the cylinder and is secured in position by a packing
plate or ring secured by screws, bolts or otherwise tightly upon it. By removing
this packing ring the cupped leather packing can be easily removed or renewed
without the necessity of lifting the ram out of the cylinder.

Improvements in Hydraulic Presses for Pressing, Bundling, or Baling
Cloth or other Textile Goods.
1, WILLIAM HUTCHINSON of Weaste, Salford, in the County of Lancaster,
Engineer, 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 :-
In hydraulic presses for baling or bundling purposes as at present usually
constructed. there are two defects which this invention is designed to remedy
(a) the uprights or standands are liable to wear loose and allow of a certain
amount of play between the base plate and the top side of same and (b) great

page_text: difficulty is experienced when it is desired to renew the cup leather packing owing
to the necessity of having to remove the ram entirely from the cylinder.
The invention consists essentially in mounting the collar or shoulder of the
standards or uprights upon which the base of the press rests upon foundation
plates so placed that all the weight of the press and the thrust comes directly upon
the standards and in securing the cupped leather packing in position by a movable
plate or washer bolted or screwed tightly down upon it so as to enable it to be easily
removed or renewed without lifting the ram from the cylinder.
The invention will be fully described with reference to the annexed drawing
which represents a sectional elevation of hydraulic baling press constructed with
my improvements.
The base of the press comprising the cylinder A and ram B and the top C are
constructed preferably as shown or of any other convenient or usual form with the
uprights or standards D which connect the top and bottom together and hold
the top C in the required elevated position. At the upper end of the standards D
are formed heads e which sustain the thrust imposed by the ram B against the
top and collars d which sustain the weight of the top and hold it in position
when the ram is withdrawn. At the lower end of the standards are formed
shoulders a similar to the heads cat the other end upon which the base of the press
rests. The standards are attached to the base and top of the press by the plates E
bolted thereto and the heads and shoulders on the standards E respectively prevent
any movement of the top and base.
Instead of as has hitherto been the case supporting the press by resting the base
or cylinder upon a foundation with an opening or space to receive the shoulders a
of the standards D, 1 fix beneath the shoulders of the standards, foundations F
preferably provided on the top with foundation plates upon which the shoulders
of the standards rest. The whole weight of the press I rest upon the shoulders of
the four standards D while the base does not rest on the foundation or support any
of the weight of the press other than by the shoulders a of the standards resting
on the foundation plates the whole weight of the press resting on these shoulders.
The foundation plates are fixed upon a bed of masonry concrete or the like to
rigidly fix them. By this arrangement should any wear take place between
the base of the press and the shoulders a the press gradually settles down and
no looseness or lifting of the standards D occurs when the press is in use and the
ram lifted.
I fit the cup leather packing G into a groove y cut out of the top inner edge of
the cylinder A and secure it in position by a packing plate or ring H secured by
screws or bolts h tightly upon it. By removing the packing ring H the cupped
leather packing G can be easily removed or renewed without the necessity of
lifting the ram out of the cylinder.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. An hydraulic press constructed and arranged with a suitable foundation so that
the entire weight of the cylinder and press rests on the shoulders of the standards and
through them on the foundation while the base is not directly supported on the
foundation substantially as described and shown.
2. In an hydraulic press a cylinder having a groove cut out of the top inner edge
in combination with a plate or ring bolted thereto to secure the packing sub
stantially as an for the purposes described.
