I THOMAS MESSENGER, of 2 Clarence Lawn, Dover, in the County of Kent,
Engineer, do hereby declare the nature of this invention to be as follows:-
This Invention relates to an improved machine for making into pellets, balls,
"briquettes," or any convenient shape, substances suitable for fuel and other
purposes.
My improved machine is designed to perform simultaneously the operations of
filling, compressing, and ejecting the substance under treatment; and it comprises a
novel combination of revolving shaft with eccentrics and levers, or their equivalents,
coupled to plungers, together with a die having an intermittent rotary movement and
retained in position by a locking arrangement during the period of time when the
plungers are entering and leaving the die.
In order that my invention may be readily understood I will now describe it by
reference to the accompanying 2 sheets of drawing, upon which :-
-
Figure 1 is an elevation of a machine embodying my improvements.
Figure 2 a plan of same.
Figure 3 an elevation at one end.
Figure 4 a sectional elevation through the die, and
Figure 5 a sectional elevation at the end opposite that shown Fig. 3.
Similar letters of reference. indicate similar parts in each of the figures
respectively.
My machine consists of two eccentrics, A and A', fixed on a revolving shaft B,
one of these (A) is coupled to the lever C, and the other (A') to the lever D, and also
to the levers E and E¹..
The upper ends of these levers are attached to the filling plungers F, to the
compressing plungers F¹, and to the ejecting plunger F³.
In the drawings these plungers are all shown as having completed their. inward
stroke, and they all work into holes in a die G which has an intermittent revolving
movement; this die has three lugs formed around its periphery at even distances
apart so that it may be locked at the right period of time, as hereinafter
described.
This intermittent revolving movement through an angle of 120° is produced by
the crank pin H, the connecting rod I, the two toothed sectors J and K, the ratchet L,
the bevil wheels M, and the shaft M¹.

page_text: The automatic pawls N and N1 lock the revolving die G in its proper position after
its intermittent movement has been completed, so that the plungers F, F, and F, can
enter their respective holes in this revolving dic.
The pawl N is in itself automatic, the pawl N is worked off the crank pin H, the
vibrating slotted lever O. and the bevil wheels P.
In order to facilitate the following explanation of the modus operandi, it should be
stated that on Fig. 4 the pawl N is shown as it would be at the instant of locking
the die, whereas in Fig. 1 the connections for working this pawl are shown at half
stroke, in which position they would be when the plungers have completed their
inward stroke as shown in the drawing, therefore the vibrating slotted lever O is shown
broken in Fig. 1 and Fig. 4.
Qis a hopper.
The modus operandi is as follows :-
:―
The three operations of filling, compressing, and ejecting, are effected simul-
taneously.
The die G having just completed one of its intermittent rotary movements, and
the pawl N at that same instant being, by its connections with the crank pin H,
caused to approach to its nearest position to the die, as shown in Fig. 4, meets one of
the lugs formed on the die and so locks the die on this side.
At the same instant the other automatic pawl N is, by means of its spring, pushed
into gear with another of these lu s on the other side of the revolving die, thus
completely locking the die from the possibility of moving in either direction.
When the two filling plungers F, which have different strokes, the one on the filling
end of the die a long stroke, to fill in the substance entering the die only a short
distance and commences the compression of the substance, the other plunger F enters
the opposite end of the die also a short distance, forming an abutment, and has only
the same short stroke as the compressing plunger F1, being coupled to it by means of
the crosshead worked from the lever C.
The compressing plungers F, F, have a short stroke and enter the die at both ends
with a great and infinitely increasing pressure completing the compression.
The ejecting plunger F2, which has a long stroke, enters the die and ejects the
compressed substance. This plunger is longer than the others, as it is required to
pass completely through the die to do its duty, it therefore enters the die first and so
assists to lock the die in position before the other plungers enter.
Then, when the plungers have receded out of their respective holes in the die, the
next intermittent rotary movement of this die takes place, bringing it into position
for the respective operations to be again performed simultaneously, that is, the hole
from which the pellet or other. form of compressed substance was ejected comes into
position opposite the filling plungers, the hole in which the substance has been filled,
and partly compressed, opposite the compressing plungers, and the hole in which the
substance had been compressed opposite the ejecting plunger, and so forth after each
movement of the die; the three operations taking place simultaneously.
The respective short reciprocating movements of the compressing plungers, and the
longer reciprocating movements for the filling and ejecting plungers, are obtained by
means of the levers C, D, and E, which are coupled to the two opposite eccentrics A,
and A', as clearly shown in the drawings.
The effect of this mechanical combination being that a great and infinitely
increasing. pressure is obtained towards the end of the inward stroke of the
plungers.

In order that my machine may be readily understood, I will now describe it by
reference to the 2 sheets of Drawing left with the Provisional Specification, upon
which-
Figure 1. is a sectional elevation of a machine embodying my improvements.

My machine consists of two eccentrics A and A¹, fixed on a revolving shaft B, one
of these (A) is coupled to the lever C, and the other (A') to the lever D, and also to
the levers E and E¹, which may be separate as shown on the drawing, or in one
piece.
The upper ends of these levers are attached to the filling plungers F, to the com-
pressing plungers F, and to the ejecting plunger F⁹.
In the drawings these plungers are all shown as having completed their inward
stroke, and they all work into holes in a die G which has an intermittent revolving
movement; this die has three lugs formed around its periphery at even distances
apart so that it may be locked at the right period of time, as hereinafter
described.
This intermittent revolving movement through an angle of 120° is produced by the
crank pin H, the connecting rod I. the two toothed sectors J, and K, the ratchet L,
the bevil wheels M, and the shaft. M.

page_text: The die G having just completed one of its intermittent rotary movements,
and the pawl N¹ at that same instant being, by its connections with the crank pin H,
caused to approach to its nearest position to the die, as shown in Fig. 4, meets one of
the lugs formed on the die, and so locks the die on this side.
At the same instant the other automatic pawl N is, by means of its spring pushed
into gear with another of these lugs on the other side of the revolving die, thus
completely locking the die from the possibility of moving in either direction.
The two filling plungers F, (which have different strokes, the one on the filling end
of the die a long stroke, to fill in the substance, and the other a short stroke as
hereinafter mentioned) now operate. The one at the filling end enters the die only a
short distance and commences the compression of the substance, the other plunger F
enters the opposite end of the die also a short distance, forming an abutment, and has
only the same short stroke as the compressing plunger F', being coupled to it by
means of the cross head worked from the lever C.
The compressing plungers F1, F', have a short stroke and enter the die at
both ends with a great and almost infinitely increasing pressure completing the
compression.
The ejecting, plunger F, which has a long stroke, enters the die and ejects the
compressed substance. This plunger is longer than the others, as it is required
to pass completely through the die to do its duty, it therefore enters the die first,
and so assists to lock the die in position before the other plungers enter.
For some uses of my machine, compressing fuel for example, I find it preferable
to slightly taper the head of the ejecting plunger and open out the entrance to the
holes in the die to compensate for any deviation of the die from wear and tear of the
machine or otherwise.
Then, when the plungers have receded out of their respective holes in the die, the
next, intermittent rotary movement of this die takes place, bringing it into position
for the respective operations to be again performed simultaneously, that is, the hole
from which the pellet or other form of compressed substance was ejected comes into
position opposite the filling plungers, the hole in which the substance had been filled,
and partly compressed, opposite the compressing plungers, and the hole in which the
substance had been compressed opposite the ejecting plunger, and so forth after each
movement of the die; the three operations taking place simultaneously.
The respective short reciprocating movements of the compressing plungers, and
the longer reciprocating movements for the filling and ejecting plungers, are obtained
by means of the levers C, D, and E, which are coupled to the two opposite eccentrics A,
and A¹, as clearly shown in the drawings.
The effect of this mechanical combination being that a great and almost
infinitely increasing pressure is obtained towards the end of the, inward stroke of the
plungers.
