PROVISIONAL SPECIFICATION.
Improvements in or relating to Machines for use in the Manufacture
of Confectionery.
Partly a communication from GABRIEL CARLSON, Mechanic, of 16 Fuller's Block,
in the City of Springfield, Hampden County, State of Massachusetts;
United States of America.
I, GEORGE SAMUEL BAKER of 58 City Road, in the County of London, and
Willesden Junction, in the County of Middlesex, Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to machines of the kind described in the Specification of
prior Letters Patent No. 20789 '94 granted to Gabriel Carlson, for use in the
manufacture of confectionery, its object being the construction of apparatus
which, while operating to scour and ciean the confectionery and separate the
moulding material therefrom, in the manner described in the aforesaid
Specification of prior Letters Patent, is provided according to the present invention
with improved means for picking up the moulding material and recharging the
moulding trays, therewith, and for imparting the desired finish to the recharged
trays.
According to this invention suitable rails or the like upon which the moulding
trays may travel are arranged transverse to the machine, beneath the opening in
the top of the machine through which the confectionery and moulding material
is delivered. A portion of the latter falls into the trays while some descends to
a platform beneath the trays whence it is raised in a manner to be hereinafter
described.
A conveyor which may conveniently be constructed of an endless chain pro-
vided with transverse slats passes over the surface of the trays and along the
platform beneath in such a manner that the moulding material is pushed along
the platform beneath the trays and up an inclined surface and deposited in the
trays. In order to prevent the material falling from between the slats before it
has reached a point properly over the transverse trays, a sheet of iron, or other
suitable material is arranged in a horizontal plane just above the upper surface
of the trays and below the contiguous portion of the conveyor, so that the moulding
material after reaching the top of the inclined plane, up which it is being
conveyed, is moved on to this sheet by the conveyor. This sheet instead of
stopping short directly over and parallel to the edge of the trays is cut diagonally
or in a curve, so that the moulding material drops over this slanting edge over the
whole width of the tray, by which means the trays are more satisfactorily and
evenly charged in the corners, as well as in the other parts of the tray than would
result if the edge of the sheet ceased at a line parallel to the direction of travel
of the trays.
The close contact of the filling slats or conveyors with the trays which are being
filled causes these slats also to perform the work of continuously striking or

page_text: levelling the moulding material; and by means of the contact of the slats or
conveyors with the trays over which they move crosswise, while both are in motion,
a diagonal movement is given to the material as it fills into the trays thereby
effecting the filling of the trays in the most regular and satisfactory manner.
In the machine at the place where the charged trays issue is hung a plate
arranged slightly diagonally and in such a manner that its lowest edge scrapes the
upper surface of the trays and smooths off the moulding material, thougn this
process has already been more or less perfectly performed by the slats or conveyors
and the horizontal iron sheet previously described.
The arrangement of the sieves and cleaning devices for treatment of the
confectionery can be substantially as described in the specification of the
above-mentioned prior patent.
The wheels over which the conveyor passes are preferably four in number,
though more or fewer than this may be employed if desired.
With regard to the gearing employed to move the trays through the machine
for recharging and for operating the conveyor, it may conveniently comprise two
shafts at right angles to each other, one operating the trays, and the other the
conveyor. These shafts are geared together by suitable toothed gearing and one
or other of them is connected by other gear to the main driving shaft of the
apparatus, the ratio of the gearing being such that the angular velocity of the
driven shafts is suitably reduced relatively to that of the driving shaft upon which
the usual fast and loose pulleys may be placed.

Improvements in or relating to Machines for use in the Manufacture
of Confectionery.
Partly a communication from GABRIEL CARLSON, Mechanic, of 16, Fuller's Block,
in the City of Springfield, Hampden County, State of Massachusetts, United
States of America.
I, GEORGE SAMUEL BAKER of 58, City Road, in the County of London, and
Willesden Junction, in the County of Middlesex, 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 relates to machines of the kind described in the Specification
of prior Letters Patent No. 20789/94 granted to Gabriel Carlson, for use in the
manufacture of confectionery its object being the construction of apparatus which,
while operating to scour and clean the confectionery and separate the moulding
material therefrom in the manner described in the aforesaid Specification of
prior Letters Patent, is provided according to the present invention, with improved
means for picking up the moulding materal, and recharging the moulding trays
therewith, and for imparting the desired finish to the re-charged trays.
According to this invention suitable rails or the like upon which the moulding
trays may travel are arranged transverse to the machine, beneath the opening in
the top of the machine through which the confectionery and moulding material
is delivered. A portion of the latter falls into the trays while some descends to
a platform beneath the trays whence it is raised in a manner to be hereinafter
described.
A conveyor which may conveniently be constructed of an endless chain provided

page_text: the chains may be taken up. A sloping board or metal sheet H is arranged
transversely across the receptacle E; the upper part of this board or sheet is
carried over the upper chain wheels at that end; the whole board being arranged
in such proximity to the slats that as the chain wheels rotate the slats draw the
material in the direction indicated by the arrows, along the bottom of the
receptacle E and up the inclined surface of the board. A disposing plate" J
preferably formed of a metal sheet is arranged in a position so as to lie just over
the top of the tray E as it passes through the machine. This sheet J stretches
across the machine and at one end J is curved down against the inner surface
of the conveying slats. The other end of this sheet J2 is cut at an angle
in Fig. 5, this slanting portion leaving triangular shaped opening above the
trays D, through which opening the material as it is drawn over the sheet J by
the slats of the conveyor F is fed into the trays; the effect of this diagonally-cut
plate being that the material is evenly disposed all across the trays.
as shown
The trays D are fed through the machine by means of an endless chain K
carrying fingers K¹ and running over chain wheels L L', motion being imparted
to the former of these wheels through the shaft M at one end of which it is
mounted, the other end of the shaft carrying a bevel wheel M', which gears with
another bevel wheel N upon a shaft Ni arranged transversely to the machine.
This shaft N is that which also carries two of the chain wheels G and, on the
other end of the shaft at the opposite side of the machine a larger gear wheel N².
This wheel gears with a pinion O upon a shaft O', which carries at its other end a
large gear wheel 02, this latter gear wheel in turn engaging with a pinion P upon
a shaft P¹ which carries a fly-wheel and fast and loose pulleys.
It will be seen that by this arrangement motion is imparted to the conveyor F
and to the trays D at a speed sufficiently. réduced for the requirements of filling
up the latter. The trays D run upon preferably wooden rails D', arranged across
the machine and projecting on either side sufficiently to allow of one or more tray:
resting on them at either side of the machine, the empty trays being fed in at
the right-hand side of the machine, as seen in Fig. 4, the charged trays being
removed through the left-hand side.
By arranging the disposing plate J sufficiently close to the top of the trays D,
a smooth or more or less finished appearance is imparted to the surface of the
moulding material but if desired, a further finishing may be given to the surface
by a plate R hung loosely from the casing of the machine over the opening through
which the charged trays issue; this plate being so adjusted that its lower edge may
scrape over the top of the trays and remove the surplus material.
If desired instead of the edge J2 of the sheet J being cut at an angle as shown
in Fig. 5, it may be curved or otherwise suitably shaped in order to cause the
moulding material to be fed uniformly across the whole width of the trays D.
It will thus be seen that the trays in addition to being filled by means of th
converging slats have the surface of the starch deposited in them struck off or
levelled first by these slats, then by the plate J and lastly by the plate R.
The starch, which is the moulding material usually employed in these machines
is not easy to manipulate, but it is found that by means of conveying slats moving
across the trays and close to the upper surfaces of the latter, with a "disposing
plate" arranged in the manner above described, the moulding trays may be
satisfactorily filled.
A conveyor may be arranged beneath the rails D₁ which project upon the
left-hand side of the machine, in order to remove any starch falling from the
charged trays after they leave the interior of the machine and to transfer it into
the receptacle E.
If desired the above described arrangement for filling the mould trays may be
constructed as a separate machine.
No reference is made to the apparatus arranged at the end Q of the machine
as this is fully described in the prior specification to which reference has already
been made.
