page_text: Improvements in Machines or Apparatus for Packing Tea or other
Analogous Products into Chests or Boxes.
I, WILLIAM JACKSON, of Thorn Grove, Mannofield, Aberdeen, N.B., Engineer,
do hereby declare the nature of this invention to be as follows:-
'
My invention relates to machines or apparatus for packing tea or other analogous
products comprising a platen or table, on to which a chest or box is temporarily
placed and secured, and to which a vibratory or shaking motion is imparted for
the purpose of causing the dry tea leaves or other products to work down and
pack themselves closely together in the said chest or box.
It has been usual hitherto in machinery of this description to carry the platen
or table supporting the chest or box on links, pivots, rods, spiral springs or the like
which are direcly supported beneath on the bed or foundation plate of the machine.
According to my invention I mount or carry or wholly suspend the platen or
table by means of plate springs, the platen or table having no direct connection
with or support from the bedplate beneath it.
To
In an apparatus constructed according to my invention, behind the platen or
table and towards the back end of the bed-plate, I provide on the bed-plate a sup-
port or supports which may be either cast with, and form part of the said bed-
plate or be separate therefrom and attached thereto by any suitable means.
these supports are firmly secured the rear ends of two plate springs of steel or other
suitable material which are preferably of considerable breadth and gibbet shaped
so as to be sufficiently strong to sustain the platen and any weight that may be
placed upon it.
The said plate springs project over the bed-plate to receive between them at
their front ends the aforesaid platen or table.
The plate springs in addition to relieving the platen of all direct supporting con-
nections beneath also deaden the vibratory action of the platen and render it
easy to drive. Instead of the plate springs being firmly secured to the aforesaid
supports the plate springs may be hinged or pivoted thereto in which case instead
of springs rigid plates may be employed.
The chest or box is held in position on the platen or table between a fixed
adjustable clamp and a clamp operated by means of a screw.
When packing a chest with tea for example the springs allow of the necessary
vibrating action being imparted from a driving shaft by means of a crank pin or
eccentric and connecting rod attached to the platen or table.

Analogous Products into Chests or Boxes.
I, WILLIAM JACKSON, of Thorn Grove, Mannofield, Aberdeen, North Britain,
Engineer, 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: -
My invention relates to machines, or apparatus, for packing tea, or other analo-
gous products, into chests or boxes, the said machines comprising a platen or table,
cnto which the chests or boxes, are temporarily placed and secured, and to which
a vibratory, or shaking motion is imparted for the purpose of causing the dry tea
leaves, or other material to be packed, to work down and become closely packed
together in the chest or box.
It has been usual hitherto, in machinery of this description, to carry the platen,
or table, supporting the chest, or box, on links, pivots, rods, spiral springs, or the
like, which are directly supported beneath on the bed, or foundation plate, of the
machine.
According to my invention, I mount or carry, or wholly suspend, the platen, or
table, by means of spring plates or plates which will yield or are capable of moving
sideways, the platen or table having no direct connection with, or support from,
the bed or foundation plate beneath it.
In an apparatus constructed according to my invention I provide towards the
back end of the bed-plate a support, or supports, which may be cast with the said
bed-plate, or be attached thereto by any suitable means. To this support, or these
supports, are firmly secured, or hinged or pivoted, the rear ends of spring or
yielding plates, which may be of steel, or other suitable material, and of a sufficient
breadth to be strong enough to sustain the platen, or table and any weight that
may be placed upon it. The said spring or yielding plates, project over the bed-
plate and to their forward part is secured the platen or table, to which the chests
or boxes are clamped.
The platen or table can be very easily operated by any suitable driving gear
such for example as a driving shaft and a crank pin, or eccentric and connecting
rod attached to the said platen or table and the arrangement will deaden or cushion
the transmission of vibrations to outside the machine.
I will describe with reference to the accompanying drawing apparatus constructed
in accordance with my invention, I do not limit myself to the precise details shewn.
Figure 1 represents in side elevation, Figure 2 in front elevation and Figure 3
in plan, one form of the apparatus and Figure 4 is a view similar to Figure 1
shewing a modification.
Cast with the bed plate, or base A at the rear end therecf are two standards B,
to each of which is rivetted a broad spring plate C (Figures 1, 2, and 3) extending
from the standards B to preferably, beyond the front end of the bed plate. The
outer or free ends of these spring plates (are rivetted to brackets a carrying
the platform, or table D upon which the chests or boxes to be packed are placed,
the said platform, or table, being thus suspended, or carried, by the said spring
plates free from the bed plate A. On the underside of the platform or table D,
are lugs 6 through which a pin is passed to which one end of a rod E is connected
the opposite end of the said rod being formed so as to constitute the strap of an
eccentric d carried on a shaft F mounted in bearings e on the bed plate A, and
receiving rotary motion, from any suitable motor, by means of a strap passing
round a pulley f fast on the shaft F. The box or chest G to be packed is placed
on the platform, or table D so that it bears against an abutment or bracket H

page_text: which is adjustable in position on the said platform or table, to suit boxes or
chests of different sizes, the said box or chest being securely retained in position
against the abutment or bracket H, by a screw I working in a screw nut K, on one
of the brackets a. The screw I is provided with a handle L, on its outer end,
and its inner end is connected, by a swivel joint, to a plate M, so that by rotating
the screw I in the nut K in the proper direction, the plate M is forced forward
so as to clamp the box or chest tightly between the said plate M, and the fixed
abutment or bracket H. A roller, (or several rollers), such as is shewn at g, may
be provided in the platform, or table, D, to facilitate the placing of the boxes, or
chests, in position on the table, and their removal therefrom. When the shaft F
is rotated, a reciprocating or vibratory motion, is, through the eccentric d and
rod E imparted to the table, or platform D, and consequently to the chest, or
box G, which will cause the tea or other material contained in the box, or chest,
to work down, and become packed closely in the said box, or chest. The spring
plates C, while permitting of the vibratory motion being imparted to the table, or
platform, D, render the operation of the table easy. Instead of the spring plates C,
being rivetted, or bolted, to the standards B, they may be hinged thereto and in
this case, instead of spring plates, rigid plates may be used
in Figure 4. Instead of an eccentric for imparting the reciprocating
movement to the table D, cranks, or other suitable means, may be
employed for the purpose, and the details of construction may be otherwise varied
without departure from the nature of my invention.
as shewn
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is;-
1. In a machine for packing tea or other material in boxes or chests, a suspended
table or platform, for supporting the chest, or box, to be packed and means for
imparting a reciprocating or vibrating motion to such table or platform, sub-
stantially as hereinbefore described.
2. In a machine for packing tea or other material in boxes or chests, a table
or platform for supporting the boxes or chests, to be packed, connected by spring,
or vibratory, or sideway moveable, plates, to fixed, or stationary, supports, .or
standards, so that the said table, or platform, is entirely supported by the said
plates, and means for imparting a reciprocating, or vibrating, motion to the table,
or platform, substantially as herein before described.
3. The combination and arrangement of parts constituting the machine or
apparatus for packing tea or other material, in boxes or chests, substantially as
herein before described and illustrated in Figures 1, 2 and 3 of the accompanying
drawings and also the modification illustrated in Figure 4.
