Improvements in Machinery or Apparatus for Trussing and Pressing
Hay, Straw, Clover, or other Material.
JOSEPH BRADBURY of Brook Iron Works Charles Street Manchester in the County
of Lancaster Engineer do hereby declare the nature of this invention to be as
follows:-
In carrying out my invention I mount in brackets upon the side frame of an
ordinary trussing machine a horizontal shaft passing underneath the table of the
machine. On one end of this shaft I mount an internal toothed spur wheel which
internal spur wheel is actuated by a pinion keyed upon a short shaft mounted in
brackets upon the frame of the machine. Upon an extension of one of the brackets
carrying the short shaft is mounted a fork hand lever provided with a catch passing
through in the fork of such lever; this catch being held down by means of a weight
being bolted on the top of the catch. This catch is designed to engage with &
actuate a ratchet wheel keyed upon the short shaft by which means motion is imparted
through the pinion to the internal toothed wheel. This catch of the forked lever is
continued outwards at each extremity and caused to slide over cams cast to the
brackets carrying the forked lever so lifting the catch out of gear when desired. The
internal spur wheel herein before mentioned is also provided with a bevil wheel cast
upon one side into which is geared a hevil pinion mounted upon & actuated by a
vertical shaft which vertical shaft is actuated by a handle mounted upon the upper
extremity.
In order to lift the bevil pinion out of gear I provide a quadrant mounted upon a
stud one end of this quadrant provided with a cam to engage & lift the bevil pinion
out of gear.
This hook or
Instead of using the bevil pinion and quadrant I sometimes employ a groved worm
fitted with hooks or claws with guide fastened to horizontal shaft.
claws being designed to engage with chain fastened to lid.
The object of this double arrangement is as follows
Upon the hay straw clover or other material being placed upon the table of the
machine, the operator places his hand on the lid or presser of the machine (this
lid or presser being mounted in the ordinary well known manner) descends quickly
upon the hay, straw, clover or other material being pressed. The chains drop through
the guide herein before mentioned, the hand lever being brought over which causes
the catch to slide down the cam and engage with a ratchet wheel which actuates the
horizontal shaft & the hook or claws hereinbefore mentioned falls in between the
links of the chain. A stop catch is provided to lock the ratchet wheel when
the forked lever is taking its backward stroke & so the hook or claws herein before
described remains in the chain while pressing the hay, straw, clover or other meterial
and then an ordinary lever being used to liberate the stop catch.

Improvements in Machinery or Apparatus for Trussing and Pressing
Hay, Stray, Clover, or other Material.
I JOSEPH BRADBURY of Brook Iron Works Charles Street Manchester 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 order that this invention may be readily understood and carried into practical
effect I have hereunto annexed a sheet of drawings illustrative of the same in which

page_text: Fig. 1 is a side view and Fig. 2 a plan of a trussing and pressing machine having
my improvements applied thereto. Similar Figures and letters of reference being
used in both views to denote like parts.
In carrying out my invention mount in brackets upon the side frames A of an
ordinary trussing machine a horizontal shaft B passing underneath the table of the
machine. On one end of this shaft I mount an internal toothed spur wheel C which
internal toothed wheel is actuated by a pinion D keyed upon a short shaft mounted
in brackets upon the frame of the machine. Upon an extension of one of the
brackets carrying the short shaft is mounted a forked hand lever E provided with
a catch passing through slots formed in the fork of such lever, this catch being made
sufficiently heavy so as always to fall into and engage with the teeth of a ratchet wheel
keyed upon the short shaft herein before mentioned by which means motion is imparted
through the pinion D to the internal toothed wheel C. This catch is continued outwards
at each extremity and caused to slide over cams cast to the brackets carrying the
forked lever E so lifting the catch out of gear when required.
a
To give independent motion to the shaft B when required I sometimes cast a bevil
wheel upon one side of the internal toothed spur wheel Cinto which is geared
bevil pinion F mounted upon and actuated by a vertical shaft G which vertical shaft
is actuated by a handle H mounted upon its upper extremity.
In order to lift the bevil pinion Fout of gear, I provide a quadrant I mounted
upon a stud one end of this quadrant being provided with a cam J to engage with
and lift the bevil pinion F out of gear. The quadrant I being actuated by means
of a stud mounted upon the forked lever E engaging against the quadrant I when
the forked lever E is brought over. In place of this bevil pinion F quadrant I and
cam J I sometimes employ a pair of worms K (seen more distinctly in Figs. 3, 4
and 5) keyed upon the shaft B such worms K having mounted upon them link
claws L which link claws L are provided with projections M upon their inner side
to engage with the chains N as hereinafter described. The projections R being
provided to overcome any tendency there may be for the chains N to slip.. The
action of this machine is as follows:-Hay straw or other material to be trussed or
pressed is first placed upon the table of the machine and the bands for binding the
truss are placed in position when the lid O of the machine is brought down by hand.
(This lid O is suspended by chains S from the cross roller T and is balanced by the
weight U suspended by a strap arranged to wind upon the pully V mounted upon
the cross roller T) when it will be obvious that the slack of the chains N will fall
through the link claws L. The hand lever E is now brought over by which action
the catch is caused to fall and engage with the ratchet wheel so giving motion
through the pinion D and the internal toothed wheel C to the shaft B so causing
the projections M on the link claws L to engage with the nearest links of the
chains N. The action of the forked lever E is then continued when it will be seen
that the chains N will be caused to wind round the worms K so bringing down
the lid on to the material being trussed with considerable force. When I employ
the bevil pinion F quadrant I and cam J I do not employ the worms K and link
claws L so that it will be seen that the action is as follows:-I first bring down the
lid by means of the handle H which handle being mounted upon the saine shaft as
the pinion F gives motion to the internal toothed wheel C and shaft B (the_short
shaft now revolving loose) when the chains N being attached to such shaft B are
caused to wind round the said shaft. B until the lid O is hard down upon the material
being trussed. I now bring over the the forked hand lever E which causes the catch to
engage with the ratchet wheel as hereinbefore described and at the same time lifts
the bevil pinion F out of gear by means of the quadrant I and cam J a stud being
provided upon the forked hand lever E to engage against the quadrant for this
purpose.
A stop catch P is provided for the purpose of locking the ratchet wheel in position
when the hand lever E is taking its backward stroke this stop catch P being lifted
out of gear by means of the lever which lever Q is cranked at its extremity and
caused to pass underneath the stop catch P for this purpose.

page_text: Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed and carried in practical effect I
wish it to be understood that what I claim is :-
1st. The combination and arrangement of mechanism for pressing and trussing hay
straw clover and other material as herein before described and illustrated on the
accompanying drawing.
2nd. The novel arrangement and combination of mechanism for lifting the bevil
pinion F out of gear as hereinbefore described and illustrated on the accompanying
drawing.
3rd. The arrangement and combination of mechanism for lifting the stop catch out
of gear as herein before described and illustrated on the accompanying drawing.
4th. The link claw and worm as hereinbefore described and illustrated on the
accompanying drawing.
