I, ALEXANDER CARSON, of Albert Place, in the town and County of Stirling,
Engineer, do hereby declare the nature of my said Invention for "IMPROVEMENTS
IN APPARATUS FOR PACKING TEA INTO BOXES to be as follows:-
39
The object of my Invention is to simplify and improve the construction of tea
packing apparatus of the kind described in the Specification of Letters Patent
No 4647 dated 29th September 1883.
According to the present Invention I actuate and carry the stampers, which press
or pack the tea into the boxes, by means of a disc on a rotating shaft fitted ver-
tically over the table supporting the box or boxes to be packed. Such disc being
formed with a cam groove in which are fitted the upper ends of the rods or bars
which carry the stampers. The vertical shaft is geared to and is driven by a shaft
provided with a hand crank or with a belt pulley, and both are carried in a suit-
able frame which may also form a bed for the table below. The groove in the disc
is so formed as to impart by its rotation a vertical reciprocating motion to the
stampers or pressers which press down and pack the tea in the box or boxes, and
rise gradually as each box fills or is packed; and to provide for the upward move-
ment of the stampers as the box fills the disc itself is fitted to slide on the vertical
shaft, being secured thereon by a long key or feather. The rods carrying the
stampers may be carried through guiding eyes in the framing which supports the
vertical shaft. The table which carries the tea boxes may have a jigging motion
imparted to it in the manner described in the Specification already referred to, but
as a considerable amount of power is absorbed in imparting the jigging motion
I prefer to carry the table or the boxes on springa. The action of the stampers in
pressing down the tea in the boxes imparts a vibratory motion to the boxes or the
table resting on the springs, by which means the tea is more closely packed. The
springs may however be combined with the mechanical apparatus referred to for
giving the jigging motion to the boxes. The springs also permit of yielding of the
boxes on any side when the tea may be unevenly packed into them. The use of
springs may however be dispensed with, the stampers operating alternately or in
rotation having the effect of packing the tea sufficiently close to suit the require-
ments of many tea-dealers,

page_text: I, ALEXANDER CARSON of Albert Place in the town and county of Stirling
Engineer, do hereby declare the nature of my Invention for 'IMPROVEMENTS IN
APPARATUS FOR PACKING TEA INTO BOXES;" and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
The object of my Invention is to simplify and improve the construction of tea
packing apparatus of the kind described in the Specification of Letters Patent
No 4647 Dated 29th September 1883.
According to the present Invention which is illustrated in sectional elevation,
end elevation and plan in Figures 1, 2, and 3 of the accompanying Drawings,
I actuate and carry the stampers A, A, which press or pack the tea into the boxes B
by means of a disc or boss C on a rotating shaft D fitted vertically over the table E
supporting the box or boxes to be packed, such disc being formed with a cam
groove c in which are fitted anti-friction rollers f on the upper ends of the rods or
bars F which carry the stampers A. The vertical shaft D is connected by gearing G
and is driven by a shaft H provided with a hand crank or with a belt pulley or
pulleys I, and both shafts are carried in a suitable frame J which may also form a
bed for the table below. The groove c in the disc C is so formed as to impart by
its rotation a vertical reciprocating motion to the stampers or pressers A, one of
which ascends while the other descends, and which press down and pack the tea in
the box or boxes, and rise gradually as each box fills or is packed; and to provide
for the upward movement of the stampers as the box fills, the disc itself is fitted to
slide on the vertical shaft D, being secured thereon by a long key or feather.
In order to provide means for regulating the pressure of the stampers upon the
tea, friction rings e are fitted round the shaft D, and are tightened up against it by
means of a screw nut K fitted to the disc or box C. The rods F carrying the
stampers may be carried through guiding eyes in the framing which supports the
vertical shaft, or they may be connected by a crosshead at their upper ends fitted
to slide in vertical guides L. The stampers I prefer to use are of the form shown
in the Drawings, the surface of the tea in the chest being covered by two similar
parts, into each of which two rods are fixed, but there may be four or other number
of stampers into each of which one rod is fixed; or the whole surface of the tea
may be covered by one stamper, the tea falling underneath it while it ascends,
through openings on its surface and round the edges, as in the case where there are
two or more stampers covering the surface of the tea. The table E which carries
the tea boxes B may have a jigging motion imparted to it in the manner described
in the Specification already referred to, but as a considerable amount of power is
absorbed in imparting the jigging motion, I prefer to carry the table or the boxes
on springs M as shown in Figures 1 and 2. The action of the stampers in pressing
down the tea in the boxes imparts a vibratory motion to the boxes or the table
resting on the springs, by which means the tea is more closely packed. The
springs however may be combined with the mechanical apparatus referred to, for

page_text: giving the jigging motion to the boxes. The springs M also permit of a slight
yielding of the boxes on any side when the tea may be unevenly packed into them.
The use of springs may however be dispensed with, the stampers operating
alternately or in rotation having the effect of packing the tea sufficiently close to
suit the requirements of many tea dealers.
As a means of raising the stampers and of maintaining them in their upper
position while shifting the tea boxes, I provide a screw shaft N which is operated
by gearing O from a hand wheel P, and is fitted with a screw nut Q and lifting
arm R passing under the disc or boss C, the arm R being guided by the rod S.
A rope or chain or other device may be substituted for the screw shaft lifting
arrangement.
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
First. The combination of parts constituting the improved tea packing machine
herein described.
Second. As means for carrying and operating the stampers of tea packing
apparatus, the cam disc or boss C fitted to slide upon a rotating shaft substantially
as set forth.
Third. The arrangement in tea packing apparatus, of the box supporting table
carried upon springs as and for the purpose set forth.
