page_text: I 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:-
The object of this invention is the construction of a combined weighing trussing
and pressing machine for hay straw and clover.
In carring out my invention I mount on brackets upon the side frames 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 feathered upon a short shaft mounted in
brackets upon the frame of the machine. Motion is imparted to this pinion by means
of a clutch plate provided with projections. A hand lever is further provided mounted
upon an extension of one of the brackets carrying the short shaft, this hand lever being
designed to engage with the projections upon the clutch plate. In a recess formed in
the hand lever is a spring so arranged as to force the hand lever out of gear with the
projections upon the clutch plate by a lateral motion when the machine is at rest or
in the act of being reversed. The internal spur wheel hereinbefore mentioned is also
provided with a bevil wheel cast upon one side and into which is geared a bevil wheel
mounted upon and actuated by a vertical shaft which vertical shaft is actuated by a
handle mounted upon its upper extremity. Around the outer rim of the hereinbefore
mentioned internal spur wheel I provide a band which band is continued forward and
terminates in a foot lever this band acting as a break to lessen the rebound of the
machine when the pressure is withdrawn. The object of this double arrangement of
gear is as follows
--
Upon the hay straw or clover being placed upon the table of the machine the
handle is actuated and causes the lid or presser of the machine (this lid or presser being
mounted in the ordinary well known manner) to descend quickly upon the hay straw

page_text: or clover being pressed, now the hand lever engaging with the projections upon the
clutch plate is brought into play when it will be obvious a much greater power may
be applied to press the hay straw or clover into the desired compass. The machine is
further provided with a loose platform mounted above the table upon which the hay
straw or clover is placed. This platform being mounted by means of centres passing
through the table upon a lever which lever is extended out at one end of the machine
for the purpose of carrying the weight or weights to be used in weighing the hay straw
or clover being pressed or trussed. Instead of a weight or weights I sometimes
employ a steel yard or spring balance at the extremity of the hereinbefore mentioned
lever. It will thus be apparent that by means of this combined machine hay straw
or clover may be weighed trussed and pressed at one operation.

page_text: County of Lancaster Engineer do hereby declare the nature of this invention and
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of this invention is the construction of a combined weighing trussing
and pressing machine for hay straw and clover.
In order that my invention may be readily understood and carried into practical
effect 1 have hereunto annexed a sheet of drawings illustrative of the same.
Fig. 1 is a front view.
Fig. 2 is a side view and
Fig. 3 a plan of a hay straw and clover pressing machine having my improvements
applied thereto. Similar figures and letters of referenee being used in all the views
to denote like parts.
I mount in brackets A upon the side frames B of an ordinary trussing machine a
horizontal shaft C passing underneath the table of the machine. On one end of this
shaft CI mount an internal toothed spur wheel D which internal spur wheel D is
actuated by a pinion E keyed upon a short shaft F mounted in brackets G upon the
frame of the machine. Upon an extension H of one of the brackets carrying the
short shaft F is mounted a forked hand lever I provided with a catch J passing through
slots in the fork of such lever this catch J being held down by means of a short spiral
spring K. This catch J is designed to engage with and actuate a ratchet wheel L
keyed upon the short shaft F by which means motion is imparted through the pinion E
to the internal toothed wheel D. This catch of the forked lever I is continued out-
wards at each extremity and caused to slide over cams R cast to the brackets carrying
the forked lever so lifting the catch out of gear when desirable.
The internal spur wheel herebefore mentioned is also provided with a bevel wheel M
cast upon one side and into which bevel wheel M is geared a bevel pinion N mounted
upon and actuated by a vertical shaft O which vertical shaft O is actuated by a handle P
mounted upon its upper extremity. This vertical shaft O is provided with a lever Q
to lift the bevil pinion out of gear.
Around the outer rim S of the herebefore
mentioned internal spur wheel DI provide a band T which band T is continued
forward and terminates in a foot lever T¹ this band acting as a brake to lessen the
rebound of the machine when the pressure is withdrawn as hereinafter described. I
further provide a loose platform U mounted upon centres V of a lever W which lever
is continued to centres ✗ carrying a small platform Y for carrying the weights used in
weighing the hay straw or clover. In order to balance the machine so as to give
accurate indications no matter upon what part of the platform U the load may be

page_text: placed, I provide levers a and b provided at their upper extremities with eyes to
engage with hooks e formed at the ends of a pair of levers d and e which
levers d and e are mounted upon screws provided with lock nuts for the purpose of
adjustment.
The action of this machine is as follows:-
Hay straw or clover is placed upon the platform U to the desired quantity as
indicated by the weights upon the small platform Y when the lid g is brought down by
the action of the handle P and the bevil pinion N actuating the bevil wheel M and so
causing the chains h to wind around the shaft C. When the lid g is down upon the
hay straw or clover by these means pressure is brought to bear by means of the hand
lever I being brought over which causes the catch to slide down the cams R (the
bevil pinion being first lifted out of gear by means of the lever Q) and engage with
the ratchet wheel L so actuating the spur pinion N and the spur wheel M which
enables a very great pressure to be applied to the lid g by means of the chains winding
around the shaft C. A stop catch i is provided to lock the ratchet wheel L when the
forked lever I is taking its backward stroke. The lever j being employed for releasing
this stop catch i.
The bands are now tied in the usual manner for securing the truss of hay straw or
clover and the stop catch i released when the brake T is applied to prevent a too sudden
rebound of the lid g and the truss is ready for removal. It will be obvious that a steel
yard or spring balance may be used instead of weights for taking an indication of the
weight of the hay straw or clover being pressed and trussed.
Having thus particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I wish it to be under-
stood that I do not confine myself to the precise details relative proportions or
deminsions of the various parts herein before described and illustrated on the accom-
panying drawing as the same may be considerable varied without departing from the
invention but what I claim is :
1st. The use and application of mechanism constituting a weighing machine in
combination with a bay straw or clover pressing and trussing machine.
2nd. The novel arrangement of mechanism for actuating the shaft Cas hereinbefore
described and illistrated on the accompanying drawing.
3rd. The arrangement of mechanism for adjusting the weighing machine so that the
load may be applied at any part of the platform as hereinbefore described and illus-
trated on the accompanying drawing.
