We, WALTER THOMSON, of Manor Lodge, Harrow, in the County of Middlesex,
Zemindar, JAMES MYLNE, of Beheea, Shahabad, Bengal, Zemindar, and JAMES
BINGHAM ALLIOTT, of Nottingham, in the County of Nottingham, 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:-
This invention has reference to apparatus for the expression of juice from sugar
cane in which vertical rolls are employed in conjunction with a suitable framework
as described in the specification of a former Patent granted to us, No 4038, dated
19 September 1881, and has for objects to simplify the construction of such mills;
to enable cheap and easily made metallic beans or frames to be used in lieu of
wooden ones for supporting the upper and lower bearings in localities where suitable
timber is scarce or dear, or under circumstances where for any reason such substitu-
tion may be advantageous, and to enable the juice tray or receiver to be readily
fixed after the rolls have been put in.
In the annexed sheet of drawings, Fig. 1 shows in rear elevation, Fig. 2 in end
elevation, Fig. 3 in longitudinal vertical section and Figure 4 in plan, a mill con-
structed in accordance with this invention.
A and B are vertical rolls such as described in the specification of the former
Patent hereinabove referred to. The upper and lower bearings of these rolls may
be of known construction but according to this invention they are supported,
adjusted and guided in and by metallic frames or beams, the construction of which
we proceed to describe, premising that although iron is preferred we do not confine
ourself to its use.
The upper frame comprises two iron bars C. C¹ which are parallel to one another
for a considerable part of their length but near the respective ends are bent or
turned inward, in such a manner that the ends at the right hand end of the mill
(Fig. 4) are in mutual contact whilst a space C* is left between the ends at the left
hand for the passage of an adjusting screwed bolt D hereinafter described.
The bars C. C' are further connected and braced by a bolt E provided with a
sleeve or distance tube E¹. F is a distance piece, shown separately in elevation in

page_text: Fig. 4. It is inserted into the space C*, and is forined as shewn to allow of the
passage of the longitudinal adjusting bolt D and one of the transverse connecting
bolts G the latter serving to fix the said distance piece longitudinally. H H are
clip plates or carriers, which, as clearly shown in Fig. 4b, embrace the two sides
and cross the bottom of the frame, and near their ends overlap and rest upon the
top edges of the bars C C³. These clip plates H. H, serve to support the top
bearings I. 11 of the rolls. J is a block which may be of wood, interposed between
the bearing and the bends of the right hand end of the frame. K is a screwed
plate or nut interposed between the bearing I and the bends of the left hand end
of the frame. The adjusting bolt D works through the distance piece F and
screwed plate or nut K as shown in Fig. 3 and its end bears against the back of
the bearing I or against a plate in contact therewith. Thus by turning the bolt D
the distance apart of the rolls A. B may be adjusted at will the outward end thrusts
of the bearings being taken by the bends of the bars C C¹ which thus serve as
abutments. The lower frame is constructed substantially like the upper one
already described and is similarly lettered, but having in addition to their other
work, to support the weight of the rolls, the clip plates or carriers are made longer
than those of the upper frame and they carry a plate or bar L whereon the lower
ends of the roll spindles work. The upper frame is carried directly by the four
legs or supports M, which carry the lower frame indirectly by means of divided
blocks or transverse bearers N which are suitably shaped and curved to fit the
legs or supports M. G. G. are transverse bolts whereby the frames and legs are
rigidly connected. Instead of the respective ends of the lower frame bars C. C¹
being bent towards each other and carried by blocks N, they may be formed with
outward bends or angles in such a manner that they may be directly connected to
the legs or supports M, and the method of connecting the ends of the bars to the
legs may be considerably varied. Figs. 4° and 4d represent a modified construction
of beam wherein one end of one bar is so turned in as to form a distance piece,
thus enabling the separate distance piece F to be dispensed with. In the modifica-
tion shown in plan or top view in Fig. 5 the left hand ends of the bars C. C¹ of
the lower frame diverge for a certain distance and then become parallel, and they
are secured between the sides of the block N and the adjacent legs or supports M
by a transverse bolt G. At O the outwardly inclined end of the bar C has a
divided ring or collar bolted to it, an arrangement which readily admits of the
ring being suitably inclined to fit one of the legs or supports M. At P the out-
wardly inclined end has curved segments bolted to it. The divided ring or collar
and curved segments are connected to their respective legs or supports by suitable
bolts. In the modification shown in Fig. 6 three of the outwardly inclined ends
or portions of the bars C C¹ are formed as screw threaded bolts suitable to pass
through the centres of legs or supports M and at right angles thereto, whilst the
fourth end or portion of bar C¹ has bolted to it, the forked extremity of a screw
threaded bolt Q. With this arrangement the bolt Q can be readily inclined to the
requisite degree for connection to a leg or support. R, R are hent pieces of sheet
metal arranged to fit the bolt-like ends of the bars and rest partly against the
exteriors of the legs M and partly within suitably shaped recesses or openings
therein, whereby an increased bearing surface is obtained. In lieu of using bent
plates or bearers such as H to carry the lower ends of the roll spindles the
lower edge of each bar C. C¹ may be provided with an inwardly projecting ledge S
whereon separate bearing or supporting bars or plates T are placed to receive the
roll spindles. The projecting ledges S may conveniently be formed by upsetting
the lower edges of the bars C C¹ at the required parts. When lower frames with
outwardly bent or inclined ends (Figs. 5 and 6) are employed, additional bolts E
and sleeves or distance tubes E¹ are used to make the frame rigid, whilst abutments
or projections to resist the outward thrust of the bearings may be provided either
by securing plates U to the inner side of each bar C. C₁ as shown at the left hand
of Fig. 5 or by providing each inner side with a projection or ridge V. In the
latter case the projection or ridge may conveniently be formed by compressing the

page_text: outer surface of the bar as indicated at the right hand of Fig. 5 and also in Fig. 6.
In Fig. 6. W is a plate fixed between the bara C. C'; through it the adjusting
bolt D passes and is thereby partly supported.
Fig. 7 is a side elevation, and Fig. 8 a plan of a modified construction of upper
beam or frame formed in one piece of cast metal such as steel. Figs. 9, 10, and 11
are transverse sections on the lines x. x; y. y; and z. z Fig. 7 respectively.
Fig. 12 is a side elevation and Fig. 13 a plan of a lower beam or frame of similar
construction. As shown, these upper and lower beams or frames are cast in one
piece and comprise side members C. C¹ connected by strengthening ribs C³, the
ends of the frames being narrowed as shown for insertion between the legs or
supports of the framework of the mill. The central rib or web C* of the upper
beam is so arranged that in addition to strengthening the beam, it serves to
prevent cane escaping upward between the rolls uncrushed, in the case where the
toothed wheels A¹ and B¹ are arranged above the beam as hereinafter described.
C³, C³ are holes for transverse fastening bolts, whilst C' is a hole for the screw
threaded adjusting bolt D, shown in dotted lines. C³, C³ are webs or plates cast
in one piece with their respective beams or frames; they serve in the case of the
upper beam or frame to support the adjustable bearings for the roll spindles (shown
in dotted lines) whilst in the case of the lower beam or frame they serve not only
to carry such bearings but also to take the weight of the rolls and attached parts.
For the latter purpose they are extended in length as shown. C is a projecting
plate or part on the lower beam or frame for carrying the rod or bar C' (Figs. 1, 3
and 4) used to prevent sugar cane falling between the rolls.
Instead of placing the toothed wheels A¹ B¹ employed for transmitting motion
from the roll B to the roll A, close to the said rolls and below the upper frame,
they may be secured to the roll spindles above the frame. By this arrangement
which is shewn in front elevation in Fig. 14 the distance between the upper and
lower beams and therefore between the bearings of the roll spindles may be
reduced, the apparatus being thereby made stronger without increasing the
thickness of the spindles.
When three or more rolls are employed. as described in the herein before
mentioned former specification, the bearings for the additional roll or rolls
may be carried by brackets secured to the sides of the frames hereinbefore
described.
In Fig. 15 is shown an underside view, of an improved construction of receptacle
for catching the juice expressed from sugar cane by the rolls, and guiding it away,
the said receptacle being adapted for a two roll mill. X is the receptacle provided
with two holes or openings X1 for the roll spindles. The metal between these
holes and the edge of the plate, forming the receptacle or guide, is cut away at X*X*
to admit of its being placed below the rolls, so that their spindles are within the
said openings without the necessity of removing or lifting the rolls for the purpose.
Y. Y. are removable pieces of metal to take the place of that cut away; each is
provided with a cross bar Y¹ the ends of which are so bent as to serve as guides
and allow the edges ✗* of the receptacle to pass between the said ends and the
adjacent surface of the metal pieces Y. Xare guides or stops on the reverse side
of the receptacle to guide and hold the metal pieces Y in place.
The position of the tray or receptacle below the rolls is indicated in Fig. 16,
which is a transverse vertical section on the line X, X, Fig. 14. Fig. 17 is a
separate view of the feed board.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is
