APPARATUS FOR FILLING OIL PRESS WRAPPERS OR ENVELOPES WITH SEED."
"IMPROVEMENTS IN
My Invention relates to apparatus having for its objects to enable the seed to be
removed from the seed kettle and placed in the wrappers or envelopes to be pressed
without material loss of heat; to spread the seed equally over the wrapper or
envelope, and thereby avoid the risk common with the present mode of damaging
the press by the undue strain arising from the variable thickness caused by unequal
spreading of the seed, and to enable a piece of ordinary unsewn bagging to be
substituted for the ordinary bag, thereby saving the cost of making the bag and
effecting an economy in bagging.
The apparatus consists of a table and of a surrounding frame or mould separate
therefrom, and just large enough to contain within it one half of the wrapper or
envelope to which it corresponds in shape and size. It forms raised sides enclosing
the wrapper and the seed placed thereon, its edges rising to a height above the
wrapper equal to the desired depth of the layer of seed. Both table and mould are
supported on an upright column fixed on a bed plate mounted on wheels so as to
be easily moved from press to press. This column consists of two parts, a solid
central portion within a tubular outer portion. One of these is a fixture to the
bed and the other is movable and slides in or upon the fixed part. The latter
supports the table, and the movable part the surrounding mould or vice versa.
will suppose, the movable part to be a plunger working within the stationary
tubular part and the mould to be connected to it. In this case it rests at the lower
end on a counterweighted lever connected to a bell crank lever one arm of which
is T shaped and projects above the table in such a position that the half of the
wrapper or envelope which is raised and thrown back rests upon it.
The weight
of this half of the wrapper is sufficient to raise the mould above the level of the
table. The height to which the mould rises is regulated by a pawl and adjustable
catch so as to give any weight of cake required.
I
A small round revolving table is provided with suitable tins or feeders fitted with
slides at bottom and with close tops to retain the heat in the seed whilst being
conveyed to the wrapper or envelope. The revolving table is mounted on wheels
and passes under the kettle mouth to facilitate the filling of the feeder.

page_text: The modus operandi is as follows:-The wrapper or envelope is placed on the
table-and-opened, the upper-half-being-thrown back until it. rests on the T end of
the bell crank lever whereby the loose mould or frame is raised around the half of
the-wrapper on the table-so as to form a suitable receptacle for the seed, and a piece
-of-bagging of sufficient-size is then-spread in position over this half of the wrapper
or envelope-
The feeder having been filled with hot seed it is drawn (its sliding bottom being
first opened) over the mould or frame which-is-thereby-filled-to-a-uniform-depth,-a-
scraper carried by the feeder bearing on the edges of the mould frame and
equalising the depth or striking off surplus seed. The ends and then the sides of
the bagging are then folded over on top of the seed and the other half of the
wrapper or envelope is closed down on top of it. The bell crank lever being thus
relieved of the weight of the wrapper, the mould or frame descends below the level
of the table so that the filled wrapper or envelope can be readily removed from the
table to be placed in the press. The mould could be filled with seed direct from
the kettle mouth if required.
