Improvements in Machines for the Manufacture of Sugar Wafers
and the like.
We JOSEPH BAKER, JOSEPH ALLEN BAKER, WILLIAM KING BAKER & GEORGE
SAMUEL BAKER all of 58 City Road in the County of Middlesex, Engineers, do
hereby declare the nature of this invention to be as follows:-
This machine is intended to be worked by hand but can be driven by power if
necessary. It consists chiefly of a chamber preferably cylindrical with flat top and
bottom supported upon suitable framework or standards. Through the centre of this
chamber runs a vertical shaft carrying a cross head or bracket having any convenient
number-say four-or six of arms whose ends form pivots to carry the boxes or plates
in which the batter is placed. Each box at its outer end is provided with a pulley or
roller which runs upon a circular track within the walls of the chamber.
In the lower part of the chamber are provided any suitable number of heating
devices preferably atmospheric gas burners over which the boxes pass in succession as
they are revolved in a horizontal plane by the vertical shaft which may be actuated in
any convenient manner by hand or power. A portion of the top or cover is pre-
ferably removed to facilitate the opening and closing of the boxes or plates for the
insertion or removal of the batter; the rest is closed in to retain the heat and with
this object in view the walls of the chamber may be made hollow and filled with some
non-conducting material.
The boxes may be revolved upon their axis by hand or by the machinery for the
purpose of presenting both sides to the action of the heat. A spur pinion upon one
end or pivot of each box gearing as the box travels round with a fixed toothed
segmental section will accomplish this.
The plates or boxes can be opened and closed by hand or automatically by means of
balance weights or springs, detents being employed if required to lock the plates when
not required to be open. The detent would be automatically fastened and unfastened
as the plates travelled round. Or the plates may be opened and closed by means of
projections working in or upon cam grooves or guides.

page_text: We, JOSEPH BAKER, JOSEPH ALLEN BAKER, WILLIAM KING BAKER and GEORGE
SAMUEL BAKER all of 58 City Road in the County of Middlesex, Engineers, 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, for the manufacture of sugar wafers and the
like, consisting of a chamber preferably cylindrical with flat top and bottom supported
upon suitable framework or standards and through the centre of which runs a vertical
shaft carrying a cross head or bracket having any convenient number-say four or six
arms whose ends form pivots to carry the boxes or plates in which the batter is placed
Each box at its outer end is provided with a pulley or roller which runs upon a
circular track within the wall of the chamber. In the lower part of the chamber aro
provided any suitable number of heating devices preferably atmospheric gas-burners
over which the boxes pass in succession as they are revolved in a horizontal plane by
the vertical shaft which may be actuated in any convenient manner.
The improvements relate to the opening and closing of the boxes and to the
fastening and unfastening of the top plates and will be understood on reference to the
accompanying drawings.
Fig. 1 represents a plan and figure 2 an elevation of a box showing its supporting
parts together with apparatus for opening and closing the upper plate or lid and
fastening and unfastening the same.
Figures 3 and 4, 5 and 6, and 7 and 8, also represent respectively plans and elevations
of boxes showing modifications of apparatus for opening and closing and fastening and
unfastening the same. Similar letters are used to indicate similar parts in the various
views.
A is the box which is suspended by pivots a within a bracket or frame B mounted
upon a shaft C. A series of boxes are arranged around the same shaft and rotate
around the centre thereof in a circular chamber the outer ends of the frames B being
supported by runners B' which travel on a rail B' fixed to the interior of the chamber.
In addition to the rotary motion around the centre of the shaft each box has a
revolving motion around its own axis imparted to it by means of a pinion D which
engages at intervals with circular racks D fixed concentrically around the shaft. The
boxes are provided with lids A' hinged at A' which have to be opened and closed
periodically for the inspection and removal of the contents. In figures 1 and 2 the
opening and closing is effected as follows. To the lid of the box are attached two
arms E within the slots e of which enter the ends of a rod E' which may be provided

page_text: with antifriction runners. To the centre of the rod E' is attached a rod E³ which
passes underneath the box through two brackets e¹ fixed thereon and at the end of the
rod is a vertical runner e³ which as the box revolves comes in contact with a cam
plate F fixed to the bottom of the chamber. As soon as the runner e comes in
contact with the cam plate it exerts a pull on the lever arms E and commences to
raise the lid A, continuing to do so until the runner reaches the apex ƒ of the cam
when the lid is fully opened as shown in figure 2.
When the runner has passed the apex of the cam the weight of the lid tends to
close the same the speed of closing being limited by the shape of the cam; the
opening and closing being effected at the same speed by the cam shown in the
drawing.
In figures 3 and 4 the opening of the lid is effected by means of a spiral spring G
one end of which is attached to a lug g fixed underneath the box A whilst the other
end bears against a pin g' on the lid A¹. The closing is effected by a fixed cam G²
against which a pin g³ projecting from the lid bears as the box revolves around its
shaft. A similar cam may also be used to limit the rate of the rising of the lid.
In figures 5 and 6 a balance weight H is attached to the lid by means of a lever
and by means of this weight the lid is raised when the fastening is released the closing
being effected either by hand or by cam as previously described and shown in figures 3
and 4.
The fastening and unfastening of the devices for securing the lid of the boxes is
effected as follows:-
Referring to figures 1, 2 3, 4, 7, and 8 it will be seen that the fastener consists of a
stud J having a cross piece j at the top and a lever arm J' underneath. The stud is
capable of turning in a lug or extension K fixed to the front of the box.
The cross
piece passes through a slotted piece J³ fixed to the lid and by turning the stud J until
the cross piece is at right angles to the stud the lid is secured. As the box rotates
within the chamber the lever arm J¹ comes in contact with two studs L L' and is
turned thereby through a quarter of a revolution one motion placing the cross piece j
parallel to the slot in the piece J³ leaving the lid free to open and the other placing it
at right angles to the slot and securing the lid.
In figures 7 and 8 the lid is secured by means of a lever M pivotted at m to the
front of the box the upper end m² of the lever being bent at right angles over the lid.
The lower end m² of the lever bears in succession against two cams or inclines N N¹
the former of which causes the lever M to assume the position indicated by dotted
lines leaving the lid free and the latter causes it to assume the position indicated by
full lines thus securing the lid.
The direction in which the box is supposed to travel in order that the required
movements of the parts may take place as indicated when necessary by arrows.
Having now particularly described and ascertained the nature of our invention and
in what manner the same is to be performed, we declare that what we claim is :-
1. In a wafer making machine the method of opening and closing the lid A¹ of the
box A by means of a sliding rod such as E³ having a cross piece E at one end
engaging with slotted levers E fixed to the lid and a runner eat the other end
engaging with a fixed cam plate F substantially as described and illustrated in
figures 1 and 2 of the accompanying drawings.
2. In a wafer making machine the method of opening the boxes by means of a
spiral spring such as G one end of which is attached to the box and the other end o of
which bears against a stud or pin g¹ projecting from the lid and closing the same by
the contact of a pin such as g² with a fixed cam G³ substantially as described and
illustrated in figures 3 and 4 of the accompanying drawings.
3. In a wafer making machine the method of opening the boxes by means of a
weighted lever h fixed to the lid substantially as described and shown in figures 5
and 6 of the accompanying drawings.
4. In a wafer making machine the combination with apparatus for opening and
closing the boxes consisting of a fixed cam plate F actuating a sliding rod E' of

page_text: fastening apparatus consisting of a stud J having a cross head ; at the top and a lever
arm J at the bottom operated by means of two fixed studs L L substantially as
described and illustrated in figures 1 and 2 of the accompanying drawings.
5. In a wafer making machine the method of securing the lids of the boxes by
means of a hooked lever such as M pivotted to the front of the box and engaging at 5
its lower end with fixed cams or inclines such as N N¹ substantially as described and
illustrated in figures 7 and 8 of the accompanying drawings.
