PROVISIONAL SPECIFICATION.
Improvements in Baling and like Presses."
We, CHARLES THOMAS BURGESS, and WILLIAM BOWER BURGESS, both of Victoria
Works, Brentwood, in the County of Essex, Engineers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to presses such as are used for compressing hay, cotton
and other materials and are operated in many cases by hand levers. In such
presses as at present constructed, the follower or moving platform of the press
is commonly drawn upwards by chains which are wound upon barrels rotated by
ratchet and pawl gear. In the use of such presses some difficulty has been found
to arise from the unbalanced weight of the follower; according to our invention
we so arrange the chain barrels that they rise and fall with the follower of the
press but moving in the opposite direction so that the barrels and parts connected
therewith counterpoise the follower.
In the arrangement which we prefer each chain barrel is carried by arms which
are jointed to the frame of the press and the barrel has a pinion upon it at one
or both ends. The pinion engages with a toothed segment or rack also fixed
to the frame. Thus when the barrel is rotated winding up the chain and raising
the follower, the barrel itself travels down to meet the follower.
In this way
also power is more effectively applied as the follower is raised only a part of the
distance due to the winding of the chain on the barrel.
The invention is applicable also to presses in which the follower is above and
moves downwards to apply the pressure to the material. In this case balancing
is effected by the aid of a light auxiliary chain or cord passing from the follower
to the chain barrel, the arrangement being such that as the main chains are
wound up the auxiliary chain or cord is unwound and vice versa.
In place of providing tooth segments or racks for the chain barrels to travel
along, chains or cords may be employed; the chain or cord being fastened at its
ends to the framing of the press and passing one or more times around a drum
on the axis of the chain barrel.

page_text: 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:-
This invention relates to presses such as are used for compressing hay, cotton
and other materials and are operated in many cases by hand levers. In such
presses as at present constructed, the follower or moving platform of the press 5
is commonly drawn upwards by chains which are wound upon barrels rotated by
ratchet and pawl gear. In the use of such presses some difficulty has been found
to arise from the unbalanced weight of the follower; according to our invention
we so arrange the chain barrels that they rise and fall with the follower of the
press but moving in the opposite direction so that the barrels and parts connected 1
therewith counterpoise the follower.
In the arrangement which we prefer each chain barrel is carried by arms which
are jointed to the frame. of the press and the barrel has a pinion upon it at one
or both ends. The pinion engages with a toothed segment or rack also fixed
to the frame. Thus when the barrel is rotated winding up the chain and raising
the follower, the barrel itself travels down to meet the follower.
In this way
also power is more effectively applied as the follower is raised only a part of the
distance due to the winding of the chain on the barrel.
The invention is applicable also to presses in which the follower is above and
moves downwards to apply the pressure to the material. In this case balancing
is effected by the aid of a light auxiliary chain or cord passing from the follower
to the chain barrel, the arrangement being such that as the main chains are
wound up the auxiliary chain or cord is unwound and vice versa.
In place of providing tooth segments or racks for the chain barrels to travel
along, chains or cords may be employed; the chain or cord being fastened at its
ends to the framing of the press and passing one or more times around a drum
on the axis of the chain barrel.
Figure 1 is a front elevation of a portion of a press arranged in accordance
with our invention in such manner that the weight of the follower is counter-
balanced by the winding barrel and parts in connection therewith. One side
only of the press is shown-the other side is similar. Figure 2 is a side elevation
of the same.
a is one of the standards of the press, is the press head which is
here shown arranged to be readily removable and c is the follower of the press.
d is a chain attached to the follower and passing up to a barrel e on which it
can be wound; the barrel is here shown of fusee form; it is carried by radial
arms ff which are free to turn about a joint at f¹. g g are pinions fast upon
the axis of the barrel and engaging with toothed ares h h. is the lever by
which the barrel is turned; it is free to move around the axis of the barrel anl
it carries a pawl which engages with a ratchet e¹ fixed to the barrel. k is a
locking pawl which also engages with the ratchet teeth.
Figures 3 and 4 show similar views of another press in which the toothed
arcs h are replaced by chains h¹ h¹ which are wound upon the axis of the barrel
and are unwound from it as the follower is raised.
Figure 5 is a front elevation and Figure 6 an end elevation showing the way
in which we arrange the gearing in presses in which the head is movable and
is drawn down towards a stationary bed for the purpose of compressing the
material between the two. The parts, which are partly lettered in accordance
with the previous figures, are, as will be seen, so arranged that the barrel e ascends
the toothed arcs h as the movable head b¹ of the press is drawn down. Here the
balancing is effected by the aid of small supplementary chains or cords which
pass from the head around guide pulleys to fusee drums m m on the axis of the
main drums e.
Figures 7 and 8 show an arrangement similar to that represented by Figures
and 6 but in which the toothed arcs h h are replaced by chains h' as in Figures
and A

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is;
-
1. Counterpoising the follower or moving platform of a press by means of the
barrels and other parts by which the pressure is applied.
2. Presses in which the follower or moving platform is counterpoised sub-
stantially as described and shown by the annexed drawings.
