PROVISIONAL SPECIFICATION.
An Improved Measure for Measuring Tea, Coffee, Cocoa, and
the like.
| WILLIAM KENNEDY FERGUSON of 42 Bishopsgate Without, in the County
of Middlesex, Pharmaceutical Chemist, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to measure the bulk of a given weight of tea
coffee cocoa or the like.
According to this invention I make the measure of cylindrical or other suitable
form and having a plunger fitted therein so as to be capable of working up and
down and I suitably graduate the outside of said plunger to represent certain
weights for example or the graduations may be on the measure itself if such
measure is made of glass for instance in order that when the aforesaid plunger is
pulled down the measure will be opened so as to contain the desired quantity of
tea coffee cocoa or the like.
I make different graduations to suit the different substances to be measured.

An Improved Measure for Measuring Tea, Coffee, Cocoa, and
the like.
WILLIAM KENNEDY FERGUSON of 42 Bishopsgate Without, in the County
of Middlesex, Pharmaceutical Chemist, 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 :-
The object of this invention is to measure the bulk of a given weight of tea,
coffee, cocoa or the like.
According to this invention I make the measure of cylindrical or other suitable
form and having a plunger fitted therein, so as to be capable of working up and
down, and I suitably graduate the outside of said plunger to represent certain
weights for example, or the graduations may be on the measure itself if such
measure is made of glass for instance, in order that when the aforesaid plunger is
pulled down the measure will be opened so as to contain the desired quantity of
tea, coffee or the like. I make different graduations to suit the different substances
to be measured.
And in order that my said invention may be better understood I will now proceed
to describe the same with reference to the accompanying sheet of drawings in
which :-
Fig. 1 shews elevation of my improved measure.
Fig. 2 shews section of the same.
Fig. 3 shews elevation of modification of the same.
iation of wi

page_text: a shews hollow cylinder forming the measure; b plunger or moveable bottom
fixed to the end of screw c, which latter screws through the bottom of cylinder a
(Figs. 1. 2.) at d; e is a nut fixed on to the other end of screw c.
It will be seen on reference to the screw c, which is flattened on two sides, that
graduations are marked, representing grains, or other desired quantities.
At Figs. 3 and 4 I make the measure a of a portion of a tube, and the plunger
thereof another tube closed at top b, and working telescopically in the tube a; or
I may use a solid block of wood or other suitable material.
The measure a may be made of any suitable material and of any suitable form;
but if of any other form than circular in section the screw c (Figs. 1. 2) must be
fixed loosely to the plunger b, so as to communicate a sliding and not a turning
motion thereto.
When the measure is made of glass, the graduations may be thereon, instead of
on the screw or tube c as aforesaid.
Several sets of graduations may be marked on the same screw or tube. For
example there may be one set for measuring tea, another for cocoa, another for
coffee and so on.
The action is as follows; supposing for example 60 grains of tea are required to
be measured, the plunger 6 is screwed or pulled down until the space marked 60 is
seen on the screw or tube c; as shewn in the figs. Then the space between the
top of the plunger b and the top of the measure a, will be exactly sufficient to
contain the 60 grains; and so on according to the quantity required.
This measure may be used for measuring tea, coffee or other substances, where
an approximate measure only is required.
Instead of having a screw c, I may use a rod fitted in the bottom of the measure a,
so as to slide the plunger b up and down.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In measures for measuring substances such as tea, coffee, cocoa and the like,
the adjustable bottom or plunger b.
2. In measures for measuring substances such as tea, coffee, cocoa and the like,.
the adjustable bottom or plunger b, in combination with graduations marked on the
screw, rod, outer body of measure, or inner tube of same; substantially as and for
the purposes set forth.
3. Measures constructed and operated substantially as described and shewn on
the accompanying drawings.
