PROVISIONAL SPECIFICATION.
Improvements in Machinery for Pressing Hay, Straw, and other
Materials.
CHARLES STEPHENSON and WILLIAM STEPHENSON, Agricultural Engineers
of the Trent Bridge Works, Newark-on-Trent Nottinghamshire do hereby declare
the nature of this invention to be as follows:-
According to this invention we construct machinery for pressing hay, straw and
other materials, which consists of a horizontal box or chamber, into which the
material is placed, and pressed together by means of a plunger or ram, the
movement being given to the plunger or ram, by a toggle-joint, which is
held in position and working upon a fixed axis at one end, the other end
being attached to the plunger or ram, the joint of the toggle is formed in such
manner as to receive a roller. A little below the center of the toggle-joint, and at
a certain distance, is placed a lever or power-arm and which projects upward
having an opening formed in it to receive the roller on the toggle-joint, this lever or
power-arm also extends downward to the length most desired, and is placed in such
position that when the toggle is drawn together, the joint of the toggle is furthest
from the center of the lever or power-arm, but as the toggle is extended it
gradually comes nearer, so that a movement of the lever or power-arm, either way,
will give a corresponding movement to the toggle-joint. To the bottom of this
lever or power-arm, we attach a bar which extends to a gear placed at suitable
distance, and connected by a curved link, this gear is constructed with two arms,
secured to a vertical shaft, one opposite the other, and which are brought into
contact with the bar at a given point, these arms are revolved by a pole attached
to the vertical shaft, by means of animal or other power, and the outermost ends of
these arms are brought into contact with the bar first, and as the movement
proceeds, the curved connecting link causes the bar to gradually come nearer
the center, untill it arrives at a given point, when it is released, so that two
movements of the lever or power-arm are made to one revolution of the gear.

Improvements in Machinery for Pressing Hay, Straw, and owner
Materials.
CHARLES STEPHENSON and WILLIAM STEPHENSON of Newark in the County
of Nottingham, Agricultural Engineers, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
According to this invention. we construct machinery for pressing hay, straw, and
other materials, which consists of a horizontal chamber mounted upon wheels to
facilitate its transport, or if desired, may be fixed or stationary, into which the hay
or other material to be baled is fed, and is intermittently pushed or forced along

page_text: the chamber by means of a plunger or ram to which reciprocating motion is
imparted by toggle-joints, operated by a lever or arm, which is coupled to a gear
placed at a suitable distance, by means of a chain, rod, and bar, and which chain,
rod, and bar is attached to a curved link or segment upon the gear, to which move-
ment is given by arms or cams fixed to a vertical shaft, and rotated by means of a
pole, secured to the upper end of the vertical shaft, to which is attached in the
usual way, horse or other animal power, and which travels continuously around
the gear, so that two movements of the plunger or ram are effected to one revolution
of the driving shaft.
In order that our said invention may be fully understood and readily carried into
effect, we will proceed to describe the drawings hereunto annexed.
Figure 1. is a side elevation, and
Figure 2. is a plan of the same.
Figure 3. is a section of the gear, showing other details.
A is the chamber and B the hopper or opening through which the hay or other
material is fed into chamber A. C is the plunger or ram which is fitted to slide
to-and-fro in chamber A, and connected by means of toggle-joints D, D, D', D',
with cross bar E, carried by bearings in side plates F, F. The links or arms D, D,
of these toggle-joints are by preference some few inches longer than the links or
arms D, D. thereof. G is a roller fitted to rotate upon the pin or bolt D' which
couples the two arms of the toggle-joints. H is a lever or arm provided with a
elongated opening H' to receive roller G, and hanging upon axis H' which is kept.
in position by bosses provided on lever or arm Ĥ, and also those F1, F2, on side
plates F, F. the lever or arm H extends downward being formed with a foot as
shown at H to which is attached chain I by means of a clip to pin or bolt J, to
either side of the foot H³ is fixed shield K which keeps the chain I in position.
to chain I is attached rod L, which can be made any length desired. Rod L is
secured to bar M by clip and pin, and bar M is fitted to curved link N at joint M',
curved link N being secured to cross piece of frame P, by stud N', bar M is
held in place by bracket and rollers P¹. The end brackets Q are secured to
frame P, to which is fitted cross bar or bridge R which supports vertical shaft S,
to which are fixed arms or cams T, T'. U is the cap into which is fitted pole U¹
to which is attached the horse or other animal. The wheels ✗ are secured to
frame W and between frame W and gear frame P is placed batton V the whole
being rigidly fixed together, and held in position by stakes.
Or instead of the curved link N we place segment a, Figure 3, secured to cross
piece of frame P, by stud b, in place of stud N', and to the vertical shaft S is
fixed arms or cams e, e', which are brought into contact with roller d, placed at c,
the chain f being attached at one end to segment a, by pin or bolt g, and the other
end to rod L.
The operation of the machine is as follows viz. :-The hay or other material is
fed in suitable quantities into the chamber A, through the hopper or opening B.
the horse or other animal travels in the direction indicated by the arrow in
Figure 2, which rotates the vertical shaft S with arms or cams Ť, T', which are
brought into contact with roller M³ secured to bar M. As the movement proceeds
the bar M is gradually brought nearer the center by means of the curved link N,
untill the roller M² arrives at the opening T or T³, in arms or cams T, T¹ when
it is released. At the same time, with rod L being attached to bar M at one end,
and to chain I at the other, and fchain I to foot H of lever or arm H, a corre-
sponding movement must therefore be given to lever or arm H, and it will be seen,
that through the toggle-joints being fixed to cross bar E, and having roller G
fitted at D, and lever or arm H provided with a elongated opening H₁, that the
toggle-joints will be straightened and thus push or force along the plunger or
ram C with the hay or other material into chamber A. Immediately the roller M²
arrives at the opening T or T' in arms or cams T, T', the expansion of the hay or
other material in the chamber A, with the assistance of spiral spring Y, forces the
plunger or ram C rapidly backward, and through the toggle-joint, lever or arm II,

page_text: with rod L and bar M in time for the next arm or cam, so that two movements of
the plunger or ram are effected to one revolution of the vertical shaft S.
Or as shown in Figure 3, the arms or cams e, e¹, being rotated by vertical
shaft S, come into contact with roller d upon segment a, which forces the segment a
back untill the roller d, has passed around the end of the arms or cams e, el when
it is released, so that two movements of the plunger or ram, are effected to one
revolution of the vertical shaft S as above described.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. A horizontal press, for the purpose above specified, wherein the plunger or
ram is connected to toggle-joints and operated by means of a lever or arm,
substantially as, and for the purpose set forth.
2. The combination with the press of a gear, placed at a suitable distance and
connected to the lever or arm which operates the toggle-joints, by a chain, rod
and bar coupled to a curved link, and to which the movement is imparted by
arms or cams fixed to a vertical shaft, and rotated by means of a horse or other
animal attached to the pole thereof, which travels continuously around the gear,
and constructed so that the bar, as the movement proceeds, is drawn nearer the
center, untill it arrives at a given point when it is released, so that two movements
of the plunger or ram are effected to one revolution of the driving shaft, substantially
as, and for the purpose set forth.
3. The combination with the press of a gear as above described, in which is
placed a segment, and to which is coupled a chain, rod'or bar attached to the
lever or arm, the segment being operated by arms or cams rotated by a horse or
other animal, and so constructed that it is forced outwards untill the roller fixed
thereon passes around the end of the arms or cams, when it is released, so that two
movements of the plunger or ram are effected to one revolution of the driving shaft,
Bubstantially as, and for the purpose set forth.
4. The improved press consisting of the parts constructed and combined, as
described and represented by the annexed drawings, and operating substantially as,
and for the purpose set forth.
