JOHN THOMAS MOORE 48 Cemetary Road Crewe carrying on business at 29
& 31 Victoria St Crewe as Draper do hereby declare the nature of my invention for
IMPROVEMENTS IN MACHINERY FOR COMPRESSING GREEN FODDER FOR ENSILAGE
to be as follows:-
Above machine consists of 1st Strong horizontal screw with right & left hand
threads. 2nd hubs or collars in which above screw works 3rd Arms attached to
above hub or collar two arms to each hub etc these arms are again attached to a
plank or bar above & below. the right hand hub will have one arm for upper bar &
one for lower, the same with the left hub the machine is actuated by a lever handle
with ratchett & wheel attached to central screw, & pressure is obtained by placing
said machine underneath a weighted beam or attaching chains led from bottom of
silo (over rollers attached to beam on which machine stands) to hooks on top of
said machine.

Draper do hereby declare the nature of my invention for IMPROVEMENTS IN
MACHINERY FOR COMPRESSING GREEN FODDER FOR ENSILAGE, and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying drawing, being a
part of this specification:-
My Invention relates to a press especially suited for the pressure of ensilage.
The great power of the right and left hand screw, toggle arms, and knuckle joint
arrangement of press, have long been known. Also the difficulty of keeping the
screw, and follower in their true position. This invention shews how easily the true
working position of the screw shaft and follower of the machine may be maintained
by the addition of arms from a collar on the screw to the centre of the toggle arms
thus keeping the screw, and follower, in their true horizontal position, and by this
means prevent any buckling Binding or cutting of the screw threads.
This my Invention also consists of the application of an eccentric on the head of
the machine, which permits the machine to adapt itself automatically to the
material it has to press. The ensilage not unfrequently being slightly higher at
one end than the other is all pressed equally by this arrangement without in any
way straining the machine.
The following description and drawings show the press as adapted for pressing
ensilage in accordance with my Invention.
A represents the feet or follower of the press, (resting on two separate beams)
these are connected by a bar of iron or steel B. C, are the lower toggle arms
connected at their lower end to the feet or follower, and to the nuts Dat their
upper end. C are the upper toggle arms connected at their lower ends to the
nuts D. and at their upper end to the bead L.
The screw is right and left handed is carried by the nuts D and held in working
position by the arms F. and collar G. The arms F are fastened at the end nearest
the screw to collars G and the opposite ends to the centre of the toggle arms C
and C¹ which are strengthened to bear any extra strain that may be transmitted
by the arms F and occasioned by the press meeting with more resistance at one
end than the other. The collars G are lengthened so that the pin which attaches
the arm F may be the same distance from the centre of the screw as the pin which
attaches the toggles C and C. Pawls are attached to the collar G. which work in
the ratchet wheel H. these pawls are only used to prevent the machine from
unscrewing too rapidly when weights are being raised for the purpose of giving
continuous pressure. The ratchet wheel H is securely pinned or keyed to the
screw E. Upon the the screw is fastened a pairs of discs I (or a drum may be used).
these discs have a small space between them into which a wire rope can be wound
when continuous pressure is required continuous pressure or a constant and equal
pressure upon the ensilage as it sinks is obtained by means of a heavy weight
outside of the silo being wound up by means of the screw E being turned and the
rope in connection with aforesaid weight is wound between the two discs, by this
means the screw is propelled and the necessary pressure obtained.
A sprocket wheel O is rigidly fixed to the screw shaft and is used to turn the
screw. Eccentrics K. are used for gripping the chain or bars which are securely
fastened in the floor or platen of the silo or press. The grip is obtained by reason
of an eccentric being made with the upper part further from the pin on which it
works than the lower one, consequently the eccentrics will go down the bar but not
up, these eccentrics being self acting require no attention.

page_text: The pin M secures the head or backbone L. the eccentrics K. the toggles C¹ and
straps N. together.
To raise the machine to its original position pins are put through the chains or
upright bars, the eccentric is then turned over on to the head and it is then raised
by the screw.
A Stand P and pawls or cams R are placed on the beams on which the machine
rests so as to grip the bar and maintain the pressure, when the machine is taken
away.
Having thus particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
First In combination with double screw shaft, special toggle arms, short levers
and collars which maintain the aforesaid double screw shaft and follower of the
machine in their true working position as herein set forth.
Second In combination with the toggles C¹ and the head or back bone L,.
eccentric K, straps N, and pin T a self regulating head to the press for the purpose
specified.
Third In combination discs, rope, pulley block and weight arranged as herein set
forth to give continuous pressure.
Fourth A combination of stand P and pawls R as herein set forth and for the
purpose specified.
