HENRY JOHN WILLETT Duckworth Hotel Drake Street Rochdale Hotel
Manager do hereby declare the nature of this invention to be as follows:-
My invention consists of a funnel or spout (which can be attached to any vessel)
in which there are two or more divisions the space between each containing
the same capacity. The division nearest the outlet is kept shut untill the funnel or
spout is filled with the substance to be measured and then by means of a lever the
other divisions are brought to there places in the funnel, cutting off the further
supply, and at the same time the division nearest the outlet is opened and the
required measurement is delivered upon lotting go the lever the order of things is
reversed and the front division is again closed and the funnel allowed to refill.

Improvements in Apparatus for the Regular and Systematic Delivery
of any Stated Measurement of Granular or Pulverulent Material.
I, HENRY JOHN WILLETT, of Duckworth's Hotel, Drake Street, Rochdale, in
the County of Lancaster, Hotel Manager, 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 stațoment :—
The invention is primarily designed to provide an appliance for delivering from
bulk measured quantities of tea, coffee, sugar; flour or similar materials for
immediate use but it may be employed in. the packing of these articles for sale
the required quantity being delivered into a bag or other package to be subsequently
weighed if found necessary.
It consists essentially in constructing a shoot or funnel (to be attached to the
receptacle in which the material is contained) into the spout of which is inserted two
or more sliding division plates between which a chamber of any desired capacity is
formed, the sliding division plates being actuated by a lever pivoted to one of the
slides and passing through a slot or slit in the other. so that one slide is closed before
the other begins to open.
It will be fully described with reference to the accompanying drawings.

division plate closed.

to a central position.
Fig. 3. Section showing the position of the parts when the lower sliding division
plate is open to deliver the material..

canister.

I provide a funnel or shoot A to be applied to a tea canister B or other receptacle
for storing the tea, coffee, sugar, flour or other granular or pulverulent
material. In the spout CI place two or more preferably two sliding division
[Price]

page_text: plates D and E capable of being moved inwards and outwards to open or close the
spout and forming between them a chamber G of any desired capacity.
The top and bottom division plates are actuated or moved to and fro by a pivoted
lever F. The lever F is of any convenient shape and controlled by a spring H.
It is pivoted ate to the bottom division plate E and passes through a slot d in the
upper division plate D thus the pivot e on the lower plate E serves as a fulcrum for
the lever while the upper division plate D is being moved and the side of the
slot d in the upper division plate acts as the fulcrum for the lever when the lower
division plate E is being moved by this arrangement' one division plate is shut
before the other begins to move open both cutting off the supply at one time as
illustrated in Fig 2. The lever F is brought back into normal position to close
the bottom division plate by the spiral spring H.
The chamber G formed between the two sliding division plates D and E may be
of any desired capacity to contain a given weight or measurement of the material
such as a pound, half pound or quarter pound which on the closing of the upper
division plate D and opening of the lower division plate E is delivered. Upon
releasing the lever again the lower division plate E is again closed by the spring H
and the upper division plate D is opened and the measuring chamber G is
refilled.
-
The apparatus may be worked by hand on the lever For the lever F may be
actuated by suitable mechanism such as a disc wheel J and crank pinj (Fig. 4)
or by a crauk or suitable form of cam or other mechanism with a hand lever K
and in addition to this a counter and indicating appliance L may be employed
to register the quantity delivered from the apparatus.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. An apparatus for measuring and delivering measured quantities of granular
or pulverulent material such as tea, coffee,, sugar, flour or the like constructed
with a delivery funnel in the spout of which are placed two (or more) division
plates forming a measuring chamber and an actuating lever pivoted to one division
plate and resting against a slot in the other the plates alternately forming the
fulcrum for the levor so that one division plate is closed before the other is
opened substantially as described.
2. An apparatus for measuring and delivering stated quantities of granular or
pulverulent material having the several parts constructed and arranged in combi-
nation substantially as described.
