Manager do hereby declare the nature of this invention to be as follows :-
This invention relates to improvements in apparatus for dividing and measuring
dough into equal parts or portions whereby the necessity for weighing or handling the
material is dispensed with."
To this end I arrange a cylinder or other suitable chamber capable of sliding
horizontally in suitable frame work. This cylinder is provided with a piston or
movable bottom worked by meanes of a screw or by steam or other motive power
whereby the dough is forced from the cylinder through apertures formed in a horizontal
plate or entablature supported immediatly over, and in closefitting proximity to the
top of the cylinder.
On the upper surface of this plate or entablature is arranged a sliding plate or table
provided with apertures corresponding with those in the entablature, and to this sliding
plate a reciprocating motion is imparted by means of a piston rod working through
both ends of an engine cylinder mounted on a bridge springing from the entablature
plate.
I prefer that the apertures referred to, should be two in number and formed at each
end of the entablature plate.
The two corresponding apertures in the sliding table are fitted with measuring
compartments in each of which is suspended a plunger by vertical rods, the free ends
of which latter are pivoted to the ends of levers oscillating in suitable bearings or
standards supported on the sliding table. These lovers with their appendages I
designate for convenience "a rocking frame."
This rocking frame when set in motion through the agency hereinafter described
acts alternately on the slide valves of the engine cylinder by means of suitable levers
in such a way that when one end of the rocking frame say for convenience "A" is
elevated the other or depressed end "B" will operate the slide valves and cause the
piston rod to move the sliding table in an opposite direction to the other end of
the entablature, when the position of the rocking frame will be reversed, the end "B"
being now raised by the hereinafter described agency, the depressed or A " end will

again to its first position, when the movement is repeated.
The source from which the rocking frame is actuated will be understood in describing
the action of my invention which is briefly as follows-To start the apparatus the
measuring compartment say "a" of the sliding table (fitted under the "A" end of
the rocking frame) should be immediatly over the corresponding aperture in the
entablature plate.
The dough is now forced up from the cylinder underneath and entering the
measuring compartment raises the plunger suspended in same, until the compartment
is full while at the same time the plunger suspended on the other end of the rocking
frame is depressed.
This end ("B") of the rocking frame now actuates the engine cylinder as herein-
before described and the sliding table is driven to the opposite end of the entablature
plate, when the measuring compartment "6" will come in line with the corresponding
aperture in the entablature plate and the dough entering this compartment raises the
plunger suspended therein, and depressing the opposite plunger forces out or delivers
the charge of dough contained in the first described measuring compartment "a" while
the engine cylinder is again actuated as before and the sliding table moved to its first
position when the operation is automatically repeated, until the dough in the cylinder
underneath the entablature plate is exhausted.
The dough as it is delivered from the measuring compartments is received through
a frame divided into sections by cutters and called a cutting frame the sections of this
cutting frame can be made of different patterns and sizes according to the different
portions or sizes of dough required.
In order to adjust the capacity of the measuring compartments the bearings in
which the rocking frame oscillates may be either raised, or lowered, by suitable means
and thus the length of travel of the plungers in the measuring compartments altered,
whereby the portions of dough to be delivered can be measured with accuracy.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Dividing and Measuring Dough.
I MATHEW COLEMAN of 9ª Grand Canal Quay in the City of Dublin, Bakery
Manager, 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 improvements in Apparatus for dividing, or
measuring, dough into equal parts or portions whereby the necessity for weighing or
handling, the material is dispensed with.

page_text: To this end a cylinderical, or other suitably shaped vessel for holding the Dough is
arranged to travel horizontally in suitable frame work as hereinafter described.
This vessel which for convenience is called the "dough Container," is provided
with a movable bottom which is acted upon by hydraulic or other motive power
whereby the dough is forced through apertures formed in a horizontal plate or
entablature fixed on pillars over the dough container.
On this fixed plate, or entablature, a sliding plate provided with apertures corre-
sponding with those in the fixed plate, is arranged to which a reciprocating motion is
imparted by means of a piston rod working through both ends of an engine cylinder,
mounted on a bridge springing from the fixed plate.
The two corresponding apertures of the sliding plate are fitted with measuring
compartments in each of which works a plunger suspended from the free ends of
levers oscillating in suitable standards supported on the sliding plate. These
oscillating levers with their appendages I designate for convenience a Rocking
frame."
This rocking frame when actuated through the agency hereinafter described acts
alternately on the slide valves of the engine cylinder by means of levers in such a
way that when one end of the rocking frame say "A" is elevated the other end "B"
is depressed and will actuate the slide valves and cause the piston rod to move the
sliding plate in an opposite direction, when the position of the rocking frame will be
reversed; the end "B" being now raised, the depressed or A end, will act on the slide
valves of the engine cylinder and the sliding plate will be driven back again to its
first position when the movement is repeated.
The Rocking frame is actuated by the pressure of the dough, being forced from the
Dough container into one or other of the measuring compartments, and raising the
plunger suspended therein, thus imparting the movement above described.
In order that my said Invention may be more fully understood and carried into
practice I will. describe the accompanying Drawings; Fig. 1 is a front elevation
Fig. 2 a vertical section, on line X. X, of Figs. 3 and 4; Fig. 3 an end view;
and Fig. 4 a partly sectional plan on line Y. Y, of Fig. 3.
Similar letters of reference indicate corresponding parts in all the views.
C, represents the dough container which travels horizontally on guides a. a, and the
movable bottom of which, is acted upon by the hydraulic shaft D, or other suitable
motive power; E is the fixed plate, or entablature, supported on pillars b. b, and
provided with apertures c, c', (Fig. 2); F is the sliding plate which is also provided
with two apertures, or open compartments d. d', corresponding in horizontal area to
the apertures in the fixed plate or entablature.
On this sliding plate, is mounted the rocking frame, consisting of the oscillating
levers e. e, at the free ends of which the plungers f. f, are suspended which dip into
the compartments d. d', G is the engine cylinder through both ends of which works
the piston rod 9. g¹; This cylinder is mounted on a bridge h, supported on the fixed
plate, or entablature, and its valves are acted upon by the double cranks i i¹, pivoted
on the brackets k k in the manner presently described.
The working of my invention may be thus described
To start the machine the measuring compartment say d', should be immediately
over the corresponding aperture c', in the fixed plate or entablature. The dough now
being forced from the Container, into the measuring compartment d³, raises the
plunger f¹, and depressing the opposite plunger f, causes the "B" end of the rocking
frame to come in contact with the extended arm of the double crank i, which drives
the slide valve to the right whereupon the piston is also driven in the same direction
pushing forward in its course the sliding plate by means of the piston rod g', abutting
against the compartment d¹. The charged compartment d' will now overhang the end
of the fixed plate, or entablature, while at the same time the compartment d, comes into
line over the aperture c, whereupon the dough entering same lifts the plunger f, and
depressing plunger f1 causes the charge of dough in compartment d to be delivered.
Immediately on the completion of the stroke of the plungers the "A end of the
rocking frame comes in contact with the long arın of the double crank, and drives
23

page_text: the slide valve to the left causing the piston and with it the sliding plate to move in
the same direction by means of the piston rod g.
The compartment d will now again come over the original aperture c¹ and the
movement is repeated automatically until the dough in the container is exhausted.
In order to partly cut off the supply to the cylinder before the finish of the stroke, a
double pointed lever l, is fixed on a cross bar carried by the sliding plate, the extremities
of which come in contact with the short arms of the double crank i¹ thereby partly
cutting off the supply, and acting as a buffer in preventing any shock at the finish of
the stroke.
As the dough is delivered through the measuring compartments it is received
through frames H, called "cutting frames" which are slided into both ends of the
fixed plate. These cutting frames are divided by wires, or other cutters, into sections
which can be made of different patterns or sizes according to the different portions, or
sizes of dough required.
For the purpose of locking down the ends of the rocking frame, and preventing any
movement of the plungers during the travel of the sliding plate levers q q¹ are hung
on the cross bars r. 1, (Figs. 2 and 3) which catch in slots or staples tt, on the
fall of the rocking frame, and are released at the proper moment by contact with
rods, projecting from the engine cylinder.
The capacity of the measuring compartments is adjusted by either raising or lowering,
the bearings of the rocking frame by means of the hand wheel p, and bevel gear 8,
whereby the length of travel of the plungers in the measuring compartment is altered
and the portions of dough to be delivered, measured with accuracy.
An index and graduated quadrant, is shown in Fig. 1 which serves to regulate and
indicate the stroke of the rocking frame; and consequently the capacity of the
measuring compartments.
An ordinary balance, may be fitted, and worked automatically in connection with
the machine whereby the accuracy of its delivery can be checked.
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
1st. The general arrangement, and combination, of parts forming the Apparatus, or
machine, for dividing or measuring dough, and delivering same, in predetermined
portions or quantities, without the necessity of weighing; in the manner substantially
as herein described and set forth.
2nd. In the process of measuring or dividing dough, without the necessity of
weighing; the Apparatus or machine formed by the combination of the dough con-

in the manner herein specified.
3rd. In Apparatus for dividing or measuring dough, the combination formed by the
oscillating levers e, or "rocking frame" with the double cranks, and the engine
cylinder G; substantially in the manner and for the purpose herein described.
4th. In Apparatus for measuring or dividing dough, the arrangement of index, and
graduated quadrant, for indicating, and adjusting, the weight of the finished pieces of
dough to be delivered by the measuring compartments substantially as described and
set forth.
