PROVISIONAL SPECIFICATION.
An Improved Portable Press for Hay, Straw, and the like.
I WILLIAM PARKER, of 55 Skeldergate, York, Engineer, do hereby declare the
nature of this invention to be as follows
My invention relates to an improved portable press for hay, straw, and the like, and
has for object a press that can be easily and effectively worked, and at same time be
extremely portable.
In carrying out my invention, I provide a platform mounted on wheels, from which
platform at either end, rise two vertical tubes connected at the top by a crossbar,
in the centre of which is provided a ratchet roller and pulley, over which a chain
runs.
The two ends of the said chain are connected with a table, and serve to lift and
lower same when required. The said table being guided by the two aforementioned
vertical tubes at each end of lower platform.
get the power for pressing the material by means of a worm and steel wheel
which actuate two pullers fixed on a shaft at each end of the upper table, round each
of which a chain winds, the other ends of which chains being fastened to the lower
platform.
The worm slips in and out of gear so that the table can be raised or lowered
independently.
Г
I provide vertical detachable bars at each side of machine to keep the loose hay
or the like in position when being pressed.
COMPLETE SPECIFICATION.
An Improved Portable Press for Hay, Straw, and the like.
I WILLIAM PARKER, of 55 Skeldergate, York, 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 :-
My invention relates to an improved portable press for hay, straw and other fodder
and has for its object to provide a machine which will combine efficiency with extreme
portability.
My improved hay press consists chiefly of a platform carried on wheels and
supporting two uprights connected at the top by. a cross bar carrying a pulley. These
two uprights serve moreover as guides for an upper and moveable table or pressure
plate carrying the actuating mechanism which is mainly composed of a main or
driving shaft mounted in suitable bearings fixed to the said table and provided at
each end with a chain wheel or pulley upon each of which is fixed one extremity, of a
chain, whose other end is secured to the platform.
.
Upon the centre of the shaft is keyed a toothed wheel gearing with a worm,
formed in a sleeve, keyed upon a horizontal screw shaft, arranged at right angles to
the main or driving shaft. This worm being operated by a handle for the purpose of
winding the chains over their respective pulleys and hence of exerting a pressure upon
the hay placed upon the platform and between the latter and the table. Another
chain passes over the pulley fixed to the cross bar aforesaid, and bas one of its ends
fixed to the table or pressure plate while the other is wound upon a drum provided
with ratchet gearing.

P. is the platform carried upon the wheels w. w and supporting the hay bale H.
Upon the platform P are fixed two uprights u ul connected at the top by a cross
bar carrying a pulley and a hook
P
by means of which it can be suspended if
desired.
A table or pressure plate A is capable of moving up and down upon the
uprights u u¹ and carries in suitable bearings a a' the main or driving shaft S upon
which is centrally mounted the worm wheel W gearing with a worm o cut in 'a sleeve
fixed to a horizontal shaft s which is carried at right angles to the shaft S upon suit-
able bearings. The latter shaft carries at both ends a pulley d d upon which are
fixed one end of the chains C C¹ the other ends of which are hooked in any suitable
manner to the platform P.
Another chain c has one end fixed to the table A and passes around the pulley pits
other end being wound upon a drum D, provided at one extremity with a ratchet
wheel in the teeth of which engages a moveable pawl n. The shaft s is furnished
with a handle i. The worm o may be disconnected from the worm wheel W by shifting
it along the shaft 8.
The hay or other material having been piled up on the platform P, the plate A is
lowered by disconnecting the pawl n from the ratchet wheel g. Pressure is then
exerted as the plate reaches the hay by turning the handle which operates the worm o
and wheel W and winds the chains CC upon the pulleys & d¹.
The hay is tied up in the ordinary way by means of ropes, straw, or other suitable
binding material.
After the hay has been suitably pressed, the table A is raised by shifting the
handle from the worm shaft s to the axis of the drum D and winding the latter, and
with it one end of the chain e, the chains CC being meanwhile unwound from their
pulleys d. and the pawl n being in gear with the ratchet wheely to prevent the
plate A from descending.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is
The improved hay press arranged, constructed and operating substantially as and
for the purpose described.
