Improvements in Apparatus for Stamping, Forming and Delivering
Blocks or Pats of Butter or other Plastic Material.
I, JOHN CHARLES LAWSON, of No. 34, Norton Folgate, in the County of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
-
My invention relates to certain improvements in apparatus for stamping forming
and delivering blocks or pats of butter or other plastic material, and has for its
object the construction and operation of a machine which by a single movement
may act continuously and regularly.
In carrying my invention into effect I employ a containing vessel or chamber
in which the plastic material is stored, and I may also employ any suitable form of
water jacket, refrigerating appliance, or the like for the preservation of the
material within said container: The container has one or more holes formed in
the bottom or side thereof, and when charged and placed in position within the
machine a plunger is caused to impinge upon the plastic mass by the action of a
screw, controlled by a hand lever. When the material, as placed in the container
aforesaid is loose or broken, a certain degree of homogeneity is necessary and this
is obtained by the use of a slide, opening and closing from the back of the
apparatus and tightly fitting the perforated base or side of the container so as to
close the orifices. The plunger is then depressed by the screw, and the requisite
pressure imposed upon the mass to render it homogeneous without causing any of
its substance to exude. The slide may then be drawn back and locked in that
position leaving a slight projection for a purpose to be hereinafter fully described.
Below the container, and fitting the base of the apparatus, is a water tank or vessel
which may readily be removed and cleaned, in the same manner as all the other
operative parts of my said invention. A draw slide with a transverse handle bar is
arranged to work within suitable guides, and the person operating the machine
works said handle bar with one hand, and operates the pressure screw with the
The draw slide, on its outward motion, performs several functions, that is
to say by means of two cranked levers or equivalents therefor, working within
shoes to afford a certain necessary "back lash" raises a die, stamp or mould,
duplicated or multiplied to conform to the orifices in the container, and presses
sid die or stamp firmly against said orifices the second function of said slide being
to advance a locking bolt upon each side, which is structurally arranged to with-
stand the pressure now to be imposed upon the die or stamp, thus relieving the
crank levers and their supports. The screw controlling the plunger is provided
with a ratchet, the range and number of teeth corresponding to the requirements
of delivery. Said ratchet operates the hammer of an ordinary gong bell, or other
audible signal each time that a tooth clears the pawl therefor provided, and thus
causes a certain quantity of butter or other plastic material to protrude from the
container, and be pressed into the dies, stamps, or moulds. Pressing the draw
slide inwards by means of its handle bar causes a wire attached thereto to pass
between the protruded plastic material and the bottom of the container, thus cut-
other.

by the following statement:-
My invention relates to certain improvements in apparatus for stamping forming
and delivering blocks or pats of butter or other plastic material, and has for its
object the construction and operation of a machine which by a single movement.
may act continuously and regularly.
In order that my invention may be clearly understood, I have appended the
accompanying sheets of drawings, in which Figure 1 Sheet 1 is a front sectional
elevation of the apparatus upon the line DE Figure 2, and Figure 2 is an end
sectional elevation upon the lines BC Figure 1. Figure 3 is a plan, and Figure 4
an elevation of the indicating device, shown detached. Figure
Sheet 2 is a per-
spective view of one side of the lever arrangement this being duplicated in the
actual machine with synchronous movement. Figure 6 shows the tripping and
movement of the delivery plate, and Figure 7 shows a continuous feed mechanis.m
for delivery in series. Similar letters of reference are used to indicate correspond-
ing parts throughout the several views.
In carrying my invention into effect I employ a containing vessel or chamber A
in which the plastic material is stored, and I may also employ any suitable form of
water jacket, refrigerating appliance or the like for the preservation of the material
within said container A. The container A has one or more holes a a¹ all, prefer-
ably lipped, formed in the bottom or side thereof, according to the alignment of
the apparatus, and when charged with plastic material, and placed in position
within the machine as shown, a plunger F is caused to impinge upon the plastic
mass by the action of a screw G controlled by a hand lever H or an ordinary self-
acting feed. A nut I with guide rods 66¹ transmits the power to the plunger F
In order to minimise and distribute the strain due to compression I form a frame J
with webs cc, the upper end of which carries the screw G with the thrust
shoulder d and the lower ends form jaws e e¹, in which the ledge surrounding the
container A may rest, and the whole is suitably fitted within the frame of the
machine. When the material placed in the container A is loose or broken, a cer-
tain degree of homogeneity is necessary, and this is obtained by the use of a slide Y,
opening and closing from the back of the apparatus, and tightly fitting when closed
the perforations a a¹ all of the container. This slide Y is shown drawn back, and
locked by the bolt f in Figure 2, but the position of the other parts in said view
would allow of its advance for the process of compression. When in this latter
position, the plunger F is depressed by the screw G and nut I, and the requisite
pressure imposed upon the mass to render it homogeneous without allowing any
of its substance to exude. The slide Y may then be drawn back, and locked by
the bolt as shown by Figure 2, leaving a slight projection at the back of the
container for the purpose of clearing the wire g shown in section which forms
the cutting device. Below the container, and fitting the base of the apparatus is
a water tank or well K, which may be readily be removed and cleaned in the same
manner as all the other operative parts of my said invention. A draw slide L with
a transverse handle bar M is arranged to work within suitable guides hh¹, and
the person operating the machine works the handle bar M with one hand, and
operates the pressure screw by the handle H with the other. Said draw slide L
in its outward and inward motions performs several functions, that is to say by
means of two double crank levers N (one on each side) raises a die, stamp or mould,
multiplied to conform to the orifices a a¹ all in the container A, and presses said
die or stamp O firmly against said orifices. Said die or stamp is fitted into the
slides upon each side by means of wings Figure 1, and the action of the levers
are shown in detail by Figure 5 Sheet 2, hereinafter to be described. The second
function of said slide is to advance a locking bolt upon each side, which is struc-
turally arranged to withstand the pressure now to be imposed upon the die or
stamp, thus relieving the crank levers N and their supports. The screw G con-

page_text: which the stop T tips the plate upwards until it is horizontal, at which time a
horn plate U has engaged with a horizontal slide V, keeping said plate P in posi-
tion until withdrawn when it falls by reason of its poise, directly the horn plate U
is clear of the slide V. Figure 7 shows a pawl W attached to the lever arm N,
actuating a continuous slab or tray X furnished with a rack. The paper roll g
Figure 2 Sheet 1 may be similarly operated by means of a ratchet wheel and a
modification of the aforesaid pawl W.
In order to adapt my said invention to the treatment of large blocks or pats of
butter or the like, I may dispense with the mould or die O and cause paper or other
receptacles to be held under the orifices a a' all in the container A, to be filled,
and removed by the mechanism herein before described, namely, the plate P, which
may or may not be tipped in this case, and the continuous paper or tray auto-
matically moved.
