Improvements in Packing Machines.
I, PETER CHARLES LARKIN, residing at 580 Bathurst Street, in the City of
Toronto in the County of York and Province of Ontario, Tea Merchant, 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 certain new and useful improvements in packing
machines, and the object of the invention is to provide the machine with a packing.
plunger which can be easily operated with great force to reduce the bulk of the
contents of the package, and which, on its release from the application of power,
will automatically and instantaneously return to its normal position; to so arrange
the funnel and its operating parts that immédiately after the filling of the package
the funnel can be easily and expeditiously removed, leaving the top of the package
in such a condition that it can be readily closed; to provide a means for pressing
the closed top on the contents to hermetically seal the package, and prevent the
alinission to its contents of the atmosphere, with the various elements with which
it is laden; and to provide a means for easily discharging the filled package from
the machine the whole device being hereinafter more fully set forth and more
particularly pointed out in the claims.

plunger in a position about to descend.
Fig. 2 is a perspective view showing the packing plunger after having descended,
and the funnel lifted from the package.
Like letters of reference refer to like parts throughout the Specification and
drawings.
The packing machine consists of a standard A having a crane-shaped top B.
In front of the crane-shaped top B is a vertical guide C for the packing plunger D.
Connected to the front of the standard A, about midway between the crane-shaped
top B and the base E, is a table to receive the changeable moulds G. Working
vertically in the guide C is the packing plunger D. Connected to the top of the
packing plunger D is a collar H, from the side of which projects a pin I. Mounted
on the packing plunger D, below the vertical guides C, is a collar J to arrest the
upward movement of the packing plunger D on the completion of its stroke, during
its return to its normal position. The lower end of the plunger D is fitted with a
removable head K constructed to fit the interior of the funnel. Projecting from
the side of the standard A, between the table F and the under side of the craue-
shaped top B, is a pin L, and mounted on the pin L is an L-shaped lever M. The
short arm m makes with the long arm m' of the said lever an angle of approximately
one hundred and twenty-five degrees, and projects to the rear of the packing
machine. The long arm m² of the L-shaped lever M when in its normal position
is set at an angle of about forty-five degrees to the perpendicular of the machine;
thus the short arm m will be substantially horizontal. When the long arm m² of
the lever M is depressed to operate the plunger D, it moves over an arc of
approximately sixty-five degrees, which would bring the short arm m into a nearly
perpendicular position, and when the short arm is fitted with its counterbalance
the nearer to the perpendicular that the short arm is brought the less force it
.

page_text: requires to cbtinteract the weight of the counterbalance; thus enabling the
operator to apply his full strength in forcing the head of the packing plunger on
the contents of the package. In addition to enabling the operator to exercise bis
full strength where the greatest force is required, the arrangement of the arms
relieves the operator from an unnecessary application of strength where force is not
required. Projecting from the inner side of the long arm of the lever M
between the pin L and the end of the lever, is a pin N, and connected to the
pins I-N is a pitman O, by means of which the plunger D is operated by the
movement of the L-shaped lever M. Mounted on the short arm m of the L-shaped
lever M is a counterbalande P, to tatarn the lever and plunger to their normal
position when released from the application of power. Formed through the table F
is an opening Q, to receive the indifla G. Projecting upwardly from the top of the
mould G is a rectangular flange R, which'rests on the metal of the 'table Feutrotinding
the opening Q. The flange R supports the mould in position. The opening Sof
the motild G extends completely through the mould, and located in the bottom
of the opening S is the head T and upper end of a plunger U, to which the head T
is connected. The lower end of the plunger U is connected to one end of an
L-shaped treadle V, and is adapted to be raised thereby during the depression of
the opposite end of the treadle. Formed through the flange R, on opposite sides
of the middle of the opening Sare two openings W. Located within the
openings Ware the upper ends of two vortical rods X, supported in suitable guides
connected to the frame A below the table F. Connected to each of the rods X is
a pin Z, and mounted our each of the pins Z is a roller a Pivoted to the
standard Aare the forked ends of a bifurcated lever a, the forked ends of which
are so arranged as to be contiguous to the vertical rods X. The rollers a are
located on the 'top of the forked ends of the bifurcated lever a!, and by raising the
bifurcated 'lever tlie vertical rods X are lifted to their fullest capacity, and on the
release of the lever A from its lifting force the lever and rods X fall by gravity
into their normal position. To cause the sharp return of the leveria to its normal
position I connect to each of the forked ends a spring b, which is also connected to
the standard A. Hinged to the standard A, contiguous to the top of the table F,
is one end of a spring operated presser leaf, which is adapted to press down the
top of the package after it has been folded. The funnel consists of a funnel-
shaped top c, and a sleeve or box-shaped former d, counected with the funnel-
shaped top c. Each side of the former d, contiguous to the top e, is provided with
a lug or projection e, against which is adapted to operate the upper ends of the
vertical rods'
.
.
.
The operation of the machine is as follows: The package is formed on the box-
shaped former d with the bottom of the package securely closed; the funnel is
then inserted into the mould G with the bottom of the package resting ou the
head T of the 'plunger U the contents are then poured into the funnel-shaped
top'e, and descends into the package; the L-shaped lever M is then operated to
bring the head of the packing plunger sharply down on the contents of the
package, and compress them into a smaller bulk; the bifurcated levera' is then
lifted and during its lifting motion lifts the vertical rods X, which in turn -lift the
funnel from the package; the L-shaped lever M is then released, and the counter-
balance Preturns the L-shaped lever M and packing plunger D to their normal
position; the funnel is then removed, and the top of the package is folded and
closed the presser leaf is then turned down on the top of the package, and the
lever M is again operated to bring the packing plunger D with force on the
presser leaf and cause the presser leaf to-tightly close the top of the package;
the treadle Visithon operated to cause the plunger U to throw the package from
the mould 'G, after which it is labelled and sealed.
Whilst this machine is intended to be used as a tea packing machine, still I do
not confine myself to using it solely for this purpose, as I may employ it for the
purpose of packing any other compressible, unbreakable substance, which it is
required to reduce into the smallest possible'bulk.
