page_text: I, HENRY GREENWOOD, of Albion Works, Leeds, in the County of York,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a mechanical feed to apparatus in which
the material fed is to be moulded or compressed.
The invention is applicable to all kinds of moulding and compressing apparatus,
but, for convenience, I will describe it as applied to apparatus in which it is desired
to mould or compress meal for producing oil cake,
In such apparatus, it is usual to have a meal kettle, and what is termed a
strickling" box, which conveys the meal to the measuring mould of the mould-
ing or compressing apparatus from the kettle, and the present invention consists
in the means employed for mechanically operating this strickling box or its
equivalent.
The kettle is usually provided with stirrers, and the power for operating the
means above mentioned may be derived from the stirrer spindle, or independently.
In carrying out this invention, I provide a shaft which is mounted in suitable
bearings and carries a grooved cam with clutch mechanisms.
Pivotted to the base plate is a lever, which extends upwards, and is connected
either direct or through a rack and pinion, motion, to a connecting rod or rack
bar, which is pivotted to the strickling box.
This lever carries a pin which enters the groove of the cam, and as the cam
rotates, the lever is swung from side to side, and moves the strickling box in and
out.
The clutch is thrown into gear by hand by means of a system of levers and rods
within reach of the hand of the attendant.
The rack and pinion motion above mentioned will consist of a slide moving in
suitably arranged guides, and carrying the axle of a pinion which gears into a fixed
rack. On the same axle is keyed a spur wheel, of, say, three times the diameter
of the pinion which gears with the rack bar. The slide is suitably connected to the
lever, which, as it is rocked by the cam, causes the pinion to travel along the rack.
The spur wheel causes the rack bar to travel three times the distance; thus,
with a short lever, I obtain a long travel of the strickling box.

I, HENRY GREENWOOD, of Albion Works, Leeds, in the County of York,
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:-
The object of this invention is to provide a mechanical feed to apparatus in which
the material fed is to be moulded or compressed.
The invention is applicable to all kinds of moulding and compressing apparatus,
but, for convenience, I will describe it as applied to apparatus in which it is desired
to mould or compress meal for producing oil cake.
In such apparatus, it is usual to have a meal kettle, and what is termed a
"strickling" box, which conveys the meal to the measuring mould of the mould-
ing or compressing apparatus from the kettle, and the present invention consists
in the means employed for mechanically operating this strickling box or its
equivalent.
The kettle is usually provided with stirrers, and the power for operating the
means above mentioned may be derived from the stirrer spindle, or independently.
In the accompanying drawings,
Fig. 1 is a front elevation, partly in section, showing one application of my
invention;
Fig. 2 being a side view, with the compressing apparatus removed; and
Fig. 3 a plan view, with the bottom of the kettle partly removed, to show the
mechanism below.
Fig. 4 is a front elevation of a modification,
Fig. 5 being a sectional elevation taken on the line x-x, Fig. 4.
A is the kettle, B is the stirrer spindle, C is the "strickling box," D is the mould
and measuring box, and E is the compressing apparatus.
F is a horizontal shaft mounted in suitable bearings in standards F¹, fitted to a
base plate F2, and it carries a bevil wheel G, which gears with, and is driven by,
a bevel pinion B' on the spindle B.
I may here state that this shaft, or its equivalent, may be driven in any other
convenient manner, such, for instance, as by a worm G* and worm wheel G*¹, as
shown in Fig. 4.
On the shaft F are mounted loosely two grooved cams H, which are locked to
the shaft by clutches J, operated through a system of levers and rods K by the
attendant, or, it may be, by merely putting the mould or measure frame into
position.
Pivotted to the base plate 12 are levers L, which extend upwards to the strick-
ling boxes C, with which they are connected by links L', or in any other con-
venient manner.
The levers L carry bowls M, which enter the grooves in the cams, so that as the 4
cams rotate, the levers are caused to rock from side to side, and thus advance or
withdraw the "strickling" box.
In the modification shown in Figs. 4 and 5, similar letters of reference are
applied to those parts which correspond with Figs. 1 and 3.
The standards F¹ are extended upwards to carry guides N, in which an axle L 4
carried by the lever L slides, and also to form guides for the link or rod L', which
actuates the strickling box C. In the present instance, the rod L' is formed with
teeth on the underside, and thus constitutes a movable rack.

page_text: The lever L is forked at its upper end, and in the fork arms are bearings for the
axle L2 before mentioned. On the axle are mounted loosely a spur wheel O, having
attached to its side a pinion O¹. The pinion O¹ gears with a fixed rack P, carried
by the standards F1, and the spur wheel O with the movable rack L¹.
As the lever L is moved, by the action of the cam H and bowl M to the right,
to the dotted position, the pinion O₁ and wheel will be caused to rotate from
left to right by the pinion O¹ travelling along the fixed rack P.
As the spur wheel is naturally of larger diameter than the pinion, say twice, it
will cause the movable rack L₁ to travel a distance equal to twice the length of
the rack P, and thus with a short lever I may obtain a long travel of the strick-
ling box.
Similar motion may be obtained either direct, or by means of levers, actuated
either by cams or hydraulic cylinders, or by other well known mechanical means.
Having now 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:-
The means substantially as herein shown and described for mechanically operat-
ing the "strickling" box or its equivalent in moulding apparatus.
