PROVISIONAL SPECIFICATION.
Improvements in Packing Tea or other Substances in Boxes or
Containers.
JAMES AITKEN 2 Crescent Rd West Green Tottenham in the County of Mid-
dlesex Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the means of packing tea, or other substances into
boxes or containers, to the balancing of the greater part, or the whole weight of
the table, box or container, & the tea or other substances to be packed, on verti-
cally vibrated tables & obtaining suitable vibratory motions to effect the packing
of the substances.
For this purpose I employ a base plate with centres or points, & a table to
carry the box, or container, into which the substances are to be packed, on the
under side of the table are centres or points which rest on the corresponding
centres of the base plate, these centres are so arranged in such a manner that the
greater part or the whole of the weight transmitted by the table shall be balanced
on certain of the centres, when the table is vertically vibrated, and suitable cams,
or wipers, are placed under the table in such positions, that the table shall be
suitably vibrated to effectually pack the substances.
In the following statement & accompanying drawing. I describe two of the
methods as to the manner in which this is carried out.
On
(1) I provide a base plate or frame, with three points or centres arranged in
the form of a triangle, also a table for carrying the tea chest, or container, the
table has on the under side three centres, arranged to rest on the centres of the
base plate. These centres are arranged in the case of a rectangular chest or con-
tainer, so that two of the centres shall be underneath ajacent corners of the
chest, the third centre being at or near the middle of the further end of the chest
which is parallel to the two centres, also underneath the table are two rollers (or
their equivalents) at or near the two first-mentioned centres. The table is
inclined at a small angle from the two centres upwards to the third centre.
top of the table any known suitable clamping apparatus or stops is provided for
securing the chest. On the base plate is arranged a horizontal rotating shaft
parallel with the two centres with suitable cams, wipers, or trippers, (or their
equivalents) to engage on the rollers of the table, and alternately raise & let fall
the two corners of the table from & to their respective centres or points. The
table resting on the third centre continuously On the drawing Fig 1 is an
elevation Fig 2 a plan of the arrangement above described A represents the
base plate. B the points or centres C the table. E the centres on underside of
talle F. the rollers. G the shaft. H the cams & D the chest or container.
(2) In the second method. I provide a rectangular base plate, with one centre
or point in the middle of the plate, and four centres or points one at each corner,
also a table with one centre in the middle and four centres one at each corner
all on the under side. The central pivot or centre being higher than the others,

corner points of the table & base are clear of each other. I provide suitable
rollers, cams, wipers or their equivalents. & driving apparatus, to alternately raise
each corner of the table, and which allows a corresponding corner to strike a pair
of points as it depresses as shown Fig 3 is an elevation Fig 4 a plan. J is the 5

Improvements in Packing Tea or other Substances in Boxes or
Containers.
JAMES AITKEN 2 Crescent Road West Green Tottenham in the County of Mid-
dlesex Civil 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:-and drawings filed with my provisional speci-
fication.
My invention relates to the means of packing tea, or other substances into
boxes, or containers, to the balancing of the greater part, or the whole weight of
the table, box or container, & the tea or other substances to be packed, on ver-
tically vibrated tables, and obtaining suitable vibratory motions to effect the
packing of the substances.
For this purpose I employ a base plate with centres or points, and a table to
carry the box, or container, into which the substances are to be packed, on the
underside of the table are centres or points, which rest on the corresponding
centres of the base plate, these centres are so arranged in such a manner that the
greater part or the whole weight transmitted by the table shall be balanced on
certain of the centres, when the table is vertically vibrated, and suitable cams,
or wipers are placed under the table in such positions, that the table shall be
suitably vibrated to effectually pack the substances.
In the following statement and drawing filed with my provisional specification,
I particularly describe three of the methods, and manner in which this is carried
out:-
(1) I provide a base plate or frame with three points or centres, arranged in the
form of a triangle, also a table for carrying the tea chest, or container, the table
has on the underside three centres, arranged to rest on the centres of the base
plate, these centres are arranged in the case of a rectangular chest, or container,
so that two of the centres shall be underneath ajacent corners of the chest, the
third centre being at or near the middle of the further end of the chest which
is parallel to the two centres, also underneath the table are two rollers, or their
equivalents, at or near the two first mentioned centres. The table may be inclined
at a small angle from the two centres upwards to the third centre. On the top of
the table any known suitable clamping apparatus or stops is provided for securing
the chest. On the base plate is arranged a horizontal rotating shaft, parallel
with the two centres, with suitable cams, wipers, or trippers, or their equivalents,
to engage on the rollers underneath the table, and alternately raise & let fall the
two corners of the table from & to their respective centres or points on the base
plate, the table resting continuously on the third centre.
On the drawing Fig 1. is an elevation. Fig 2, a plan of the arrangement above

page_text: described. A, represents the base plate. B, the points or centres. C, the table.
E, the centres on underside of table. F, the rollers. G, the shaft. H, the cams
or wipers, & D, the chest or container.
(2) In the second method I provide a rectangular base plate, with one centre
or point in the middle of the plate, and four centres, or points one at each corner,
also a table with one centre in the middle & four centres, or points one at each
corner all on the underside, and corresponding to the respective points of the base
plate. The central pivot or centre is higher than the others, so that the table
with the container rests & is balanced on this centre, and the four corner points
of the table & base plate are clear of each other.
I provide suitable rollers, cams or wipers, or their equivalents, and driving
apparatus to alternately raise each corner of the table & which allows a corres-
ponding opposite corner to strike a pair of points as it depresses. This arrange-
ment is shown on drawing Fig 3 is an elevation. Fig 4. a plan. J, is the base
plate. K, the central pivot. L, the corner points. N. O. P. the cams or wipers
& rollers & shafts. M, the table. Q the corner points on table.
(3) In the third method I employ two tables, one at each end of a lever, or
beam, with equal arms, the centre resting on a fulcrum or point. The tables
being alternately raised by suitable cams, wipers or their equivalents fixed on a
horizontal revolving shaft.
It is obvious that two or more machines may be driven from the same hori-
zontal shaft by making the shaft of suitable length.
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 Arranging & combining three points of support in the form of a triangle
substantially as herein before described.
2-Arranging & combining one central point of support and four other points
one at each corner of a rectangle substantially as herein-before described.
3-Arranging and combining two tables one at each end of a lever with equal
arms the lever being supported in the centre substantially as herein-before
described.
4-Arranging and combining the three points of support & two cams or wipers,
substantially as herein-before described.
5 Arranging and combining one central point of support & four other points
and four cams or wipers one at each corner substantially as herein-before described.
6-Arranging and combining two tables one at each end of a lever supported
in the centre, with cams, or wipers to alternately raise each table substantially
as herein-before described.
