PROVISIONAL SPECIFICATION.
Improvements in Machines for Pressing and Trussing Hay, Straw,
and Analogous Substances.
GEORGE WOODVILLE, of 20 Lord Street, Chapel Ash, Wolverhampton in the
County of Stafford, Hay Trusser do hereby declare the nature of this invention to
be as follows:-
My invention consists in certain improvements in the construction of machines
for pressing and trussing hay, straw and analogous substances.
These improvements consist
Firstly In the means employed whereby the "pressure-board" at the finish
of its travel is in a parallel plane with that of the platform of the machine.
'
This is effected by attaching two cords, chains or wire ropes, one at each
extremity of the "pressure board" and to the upper side thereof, and passing each
upward diagonally across each, over a roller mounted in the frame or standard at
each end of the machine-the said cord then being carried downwards and round
a pulley or roller in lower portion of frame, and thence passing upwards and
connecting to the underside of the transverse extremity of the "pressure-board,"
in each instance.
Secondly In the method employed for maintaining the advance of the
descending "pressure-board" during the back stroke of the operating lever.
This is effected by attaching to the frame or standards at a convenient distance
apart, two vertical racks.
"
In conjunction with these racks are employed two pawls or arms hinged to the
suitable means
tr pressure-board and engaging in the teeth of the said racks;
being provided for disengaging the pawls in order to elevate the "pressure-board
at the end of the stroke.
Thirdly In the application of pressure by the operating lever-a rack is
employed in connection therewith to obtain the advance of the " pressure-
board."
"
Fourthly In the means for balancing the "pressure-board' -a hinged "jib"
carrying a weight at its outer extremity is attached to the lower frame; one or
more cords or chains attached to the "pressure-board" and passing over rollers
in the upper frame are connected to the "jib."

Improvements in Machines for Pressing and Trussing Hay, Straw,
and Analogous Substances.
I GEORGE WOODVILLE of 20 Lord Street, Chapel Ash, Wolverhampton in
the County of Stafford, Hay Cutter 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 presses or machines for pressing and trussing hay straw
and analogous substances and consists in certain improvements in the construction
of said machines.
On the chest of drawings annended hereunto

page_text: Fig. 1 shows a front view and Fig. 2 a side view of a machine made with my
improvements, Fig. 3 shewing a detail.
b
Upon a carriage or frame a provided with wheels a¹ and carrying the bottom
platform or table a² in the usual manner, two uprights are mounted connected at
the top to two crossbeams and stayed by the backstay 2 between the back
crossbeam and the cross rail a³ of the carriage. The pressboard c slides between
the uprights b, being guided in any ordinary suitable manner.
My improvements consist firstly in the means employed for keeping the press
board c parallel to the table a². This is preferably effected by attaching two cords
chains or wire ropes d at or near to each front corner of the pressboard c at its upper
side or near to each end of the cross rail c¹ of said pressboard, as shewn, and each
passing upwards diagonally across the other over a pulley d¹ mounted in suitable
brackets on the crossbeams of the frame near to each side of the machine, each
chain d or its equivalent being then carried downward and round a pulley d² arranged
in the lower portion of the framing and thence passing upward and being attached
to the back corner of the pressboard diagonally opposite to the point at which the
other end of the chain is attached. The board é is thereby held parallel to the
table a² during its downward or upward movement, as if one side of the board c
were depressed or raised the crossed chains would move the other side in the same
direction and consequently no tilting can take place.
My further improvement consists in means for maintaining the advance or
position of the descending pressboard during the backstroke of the operating
hand lever. These means consist in two pawls f fixed upon a rod or shaft which
is moveable in brackets g¹ attached to the cross rail e near to each end, and in two
racks hh fixed to the front side of the uprights 6 in the teeth of which said racks
engage. A handle g² is forged or fixed to the rod or shaft g by means of which
both pawls can be disengaged simultaneously when the pressboard c is to be
raised at the completion of the pressing.
My third improvement consists in the application of the pressure by means of
a rack attached to the top of the pressboard and operated by means of a pinion,
ratchet wheel and hand lever with pawl arranged at the top of the machine. I
fix two brackets ii to the top crossbeam 61 and connect them by studs 1 and 1.
Upon the former I mount a pinion m fixed or cast to the ratchet wheel m' which
can be turned by means of the hand-lever n and pawl n'. The pinion m gears with
the vertical rack o which is preferably made with deep flanges or shrouds at its
sides as shewn and is hinged to the bracket o¹ by pin o³, said bracket being fixed
to the centre of the crossrail c. On the stud a roller is mounted to hold the
rack in gear with the pinion. By this arrangement of rack the pressure is brought
to bear directly upon the pressboard without the intervention of chain pulleys and
drums as in the usual arrangement of hay presses and a greater effect is produced,
less work being absorbed in friction.
Instead of the stud / a shaft may be used supported in bearings on the cross
beam b¹ and two pinions and racks one near to each side of the pressboard c may
be employed with either one or more ratchets pawls and hand levers. Any of the
ordinary suitable means for lifting the pawls when the pressing is completed and
the board c to be raised may be used. Chains p p and balance weights p¹ are
applied to raise the pressboard when the pawl of the hand lever and the retaining
pawls are released. The arrangement of rack and pinion for pressing may be
used with other arrangements for retaining the advance of the pressboard and
for keeping the same parallel to the table a² than those hereinbefore described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same may be performed, I declare that what I
claim is
Firstly. In machines for pressing and trussing hay straw and analogous
substances, the use or arrangement of a rack or of racks connected to the top side
of the press board and of a pinion or of pinions gearing with the said rack or

page_text: racks and operated by one or more ratchet wheels pawls and hand-levers mounted
on a stud or shaft at the top of the frame, for producing the pressure substantially
as hereinbefore described and illustrated.
Secondly. In a machine for pressing hay straw and analogous substances, the
arrangement of vertical racks fixed to the side frames and of pawls for maintaining
the position of the pressboards during the backstroke of the operating hand-lever,
substantially as hereinbefore described and illustrated.
Thirdly. In machines for pressing hay straw and analogous substances the
arrangement of chains and guide pulleys for keeping the press board parallel to
the table or platform, substantially as hereinbefore described.
Fourthly. The general arrangement of a machine for pressing and trussing
hay straw and analogous substances substantially as hereinbefore described and
illustrated.
