PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Packing Tea and such like
Substances.
I, NATHAN WILLIAM HORATIO SHARPE, of 26 Perth Road, Stroud Green,
London, N., Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a means for imparting a shaking or vibratory motion to
a chest or box with the object of causing the article filled in to settle down as close
as possible and is particularly applicable for packing manufactured tea.
The apparatus consists of a suitable table to hold the chest or box held upon the
top of elastic supports, such as spiral springs, the base of which is connected to a
bedplate. Under the table is a horizontally placed shaft arranged to revolve fitted
with one or more cams which as the shaft revolves act upon the underside of table
thereby imparting a shaking or vibratory motion to the table and consequently to
what may be held upon it. The top of the table is fitted with sliding clamps to
secure the chest or box between them. These clamps may be operated in any
convenient way such as a right and left handed screw engaging underside of frame
with hand wheel attached. A collar or rim is provided to be attached round the top
of chest or box with sloping sides to prevent tea being shaken out which also protects
the lead lining from flapping and cracking.

COMPLETE SPECIFICATION (AMENDED).
Improvements in Apparatus for Packing Tea and such like
Substances.
I, NATHAN WILLIAM HORATIO SHARPE, of 26 Perth Road, Stroud Green,
London, N., 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 :-
This invention has for its object the packing of manufactured tea and like substances,
in a more perfect manner than heretofore, and by means of apparatus or machinery,
constructed as hereafter described. The said machinery is adapted to carry and hold
the box, case or the like, hereafter terined box, in which the loose substances are to
be packed, and to communicate to such box a succession of shocks, or a vibratory or
shaking motion, while the tea or the like is being placed therein.

page_text: The vibratory motion thus continued during the filling of the box materially aids
in obtaining a perfect packing of the substances, and also allows the same to be
packed with an equal density throughout.
In order that my invention may be readily understood I will describe same with
reference to the accompanying drawings.
Fig. 1, is a sectional front elevation, of such an apparatus or machine. Fig. 2, is
a side elevation of same, and Fig. 3, is a detail sectional view shewing means for
holding the box to the vibratory table. According to my invention I provide a
table A, entirely supported upon springs B,.which may be of helical form as shewn
the upper and lower ends of such springs B, being carried in sockets C in a
bedplate C. Below the table A, is a shaft D, driven by a pulley keyed thereon
and carrying one or several cams E, two such being shewn at Fig. 1. The shaft D,
is carried on the bedplate C, by suitable bearing brackets F, and passos below the
table A, the cam or cams E, being there located; in order that, upon rotation of the
shaft D, the said cams shall act upon and communicate to the said table A, a succession
of short, quick, knocks which, acting in conjunction with the springs B, carrying
the table A, give to the latter a rapid, oscillating, vibratory motion.
As will be readily understood an eccentric or eccentrics, may be mounted on the
shaft D, in place of the cams E, and as an equivalent therefore, and such eccentric
straps may be fixed to the table A.
The box or the like G, in which the substances are to be packed, is placed upon
the table A, being held by laterally movable clamp pieces H, Fig. 3. Lower
extensions of the clamps U, extend through slots A', in the table A, and a shaft I,
having a right and left handed screw thread, is carried in bearings from the lower
surface of the table, and such shaft I, is provided with a hand wheel J, by which the
shaft I, may be revolved to close together or distance the clamps H.
Detachable clamping pieces K, are suitably adjusted to the upper edges of the
box G, and these clamping pieces have sloping edges K¹ to prevent the tea being
thrown over the side of the tea box G, when the latter is nearly full and such
pieces K, also prevent the lead lining L, of the tea box from flapping and eventually
cutting, when the machine is in motion, by securing the same against outside of
tea-chest.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed 1 declare that what I claim
as my improvements in an apparatus or machinery for packing manufactured tea or
like substances, to be as follows:
1. An apparatus or machine having a table supported on springs adapted to hold
or carry a box or container, in which the substance is to be packed and to communicate
to such box or container a rapid oscillating, vibratory motion, during the filling of the
same substantially as described.
2. The apparatus or machinery essentially composed of a table to carry the box
or container springs to support the table and a rotary shaft having cams or eccentrics
located below and acting on the table to give the required vibratory motion to same
during the packing operation, substantially as described.
3. In a packer for tea leaf and the like supporting the table to hold the box to be
packed on springs substantially as described."
4. The general arrangement and combination of parts composing the machinery
or apparatus, all constructed and acting substantially as and for the purposes described
and illustrated, with reference to the accompanying drawings.
5. In a packer for tea leaf, the clamping device K, K', for the purposes stated.
