PROVISIONAL SPECIFICATION.
Screw Pressing Colander or Strainer for Extracting Moisture from
Fruit, Vegetables, and for other purposes.
I MARGARET MARY THOMAS Greenfield House Thimblemill Lane, near
Smethwick, Birmingham, Principal of School, do hereby declare the nature of this
invention to be as follows:-
To be called a screw pressing colander or strainer for extracting moisture from
fruit, vegetables, and for other purposes to be made of tin, copper, or any other
metal, in various shapes and forms, the chief feature of the invention consists
of one or more screw pius fixed to the bottom and made to stand up a few inches
above the top of the colander, a lid forming the pressure is perforated in the centre
or on each side as may be desired, the screw pins passing through this is screwed
down with a nut or lever made in various shapes, and so extracts every particle of
moisture from the contents of the colander.
One shape is made with a fixed handle soldered or riveted on each side of the
colander having a flat piece of metal at the top through which the pressing lever
passes, the screw being made shorter then the other screw pins.
Dated this 10th day of June 1891.

COMPLETE SPECIFICATION.
Screw Pressing Colander or Strainer for Extracting Moisture from
Fruit, Vegetables, and for other purposes.
I MARGARET MARY THOMAS, Greenfield House, Thimblewell Lane, near
Smethwick Birmingham, Principal of School, do hereby declare the nature of my
said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
To be called a screw pressing colander or strainer for extracting moisture from
fruit, vegetables and for other purposes to be made of tin, copper, or any other
metal, in various shapes and forms. The chief feature of the invention consists
of one or more screw pins fixed to the bottom and made to stand up a few inches
above the top of the colander a lid forming the presser is perforated in the centre
or on each side as may be desired, the screw pins passing through this is screwed
down with a nut or lever made in various shapes, and so extracts every particle of
moisture from the contents of the colander.
One shape is made with a fixed handle soldered or riveted on each side of the
colander having a flat piece of metal at the top through which the pressing lever
passes, the screw being made shorter then the other screw pins.
Having thus specified the object and nature of this my said invention I will now
proceed to describe the same reference being had to the accompanying drawings
(that is to say).
Fig. 1 is a view in elevation of a cullender, or strainer, or presser constructed
for the purposes and according to my invention with screw action.
Fig. 2 a view similar to Fig. 1.

page_text: Fig. 4 a view in elevation sectional of the lever and screw arrangement dis-
connected.
Fig. 5, a part view elevation of the same with lever and screw connected.
Fig. 6. is a view in elevation sectional shewing the handle fixed vertically but
moving upon pins.
Fig. 7. is a view in elevation shewing the handle brought down.
The same letters of reference upon the several figures indicate like or corre-
sponding parts.
a, is the body of the cullender, strainer or presser is the lid and pressing plate
C is the screw pillar, d, is the nut screwed correspondingly to c, upon which it works
e are arms for imparting a quicker movement and greater pressure, y is a vertical rod
h, is a lever, i. is the handle.
In Fig. 1. c is secured permanently to the bottom of a, at c. b may be detached
and removeable, or secured to d, so that in either movement raising or lowering it
would travel with d.
In Fig. 2 the only departure from Fig. 1 is the elongating of the stem from d
to e being screwed only at the lower part as shewn by Fig. 3 by this mode the
pressing plate b can be carried to the bottom of a, without the hand of the operator
passing into a, which in some cases would be dangerous.
In Figs. 4. 5. the lever works upon the joint h' and is provided with a slot h²
and in this the upper part of g works, controlled by the seat g' and the knob 9².
is permanently secured to b. h³ is an opening to admit of its arrangement upon c,
which is jointed at ' to accommodate itself when d, by means of e is brought down
upon g, to obtain the required pressure as shewn at Fig. 5.
In Figs. 6-7 the handle i is rivetted loosely at i- being formed as a washer
and screwed interiorly to receive c, to which is securely connected the pressing
plate and lid -the movement of e, effected by e.
It will be perceived, by each of the figures that the straining, extracting or
pressing of the substance as placed in the body of the cullender a, is effected by
pressure from screw power brought to bear upon the pressing plate b, which in each
instance serves as the lid, or cover by raising it to the proper position, any escape
of moisture or otherwise would be by the perforations at the lower part of the
cullender, or by a perforated bottom, or a wire bottom its equivalent.
In Figs. 6-7 by preference I should employ a loose bottom m, perforated and
finding its bearing upon the seat n, Fig. 6. so that in pressing brawn and the like
bodies of substance the handle i, could be brought down leaving an uninterrupted
opening at the top of a, and by reversing the said body pressure may be readily
applied to the bottom and thus force the contents out in a simple and efficacious
manner and more presentable than hitherto.
The above being my invention I wish to say that I do not confine myself to the
precise details or arrangement of parts as shewn on the accompanying sheet of
drawings but that I hold myself at liberty to alter or modify the same without
departing essentially from the principle of said invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1st. In a cullender, strainer, or presser the combination of a fixed screwed pillar
to the bottom of the vessel carrying a pressing plate and lid actuated by a screwed
nut connected to or acting with the said plate substantially as set forth.
2nd. In a cullender, strainer, or presser the combination of the rod fixed to the
pressing plate and lid, engaging with a jointed lever connected to the vessel and
engaging with said rod, which also engages with jointed screwed pillar to the vessel
actuated by a screwed nut substantially as set forthi.
3rd. In a cullender, strainer, or presser the combination of a jointed and moveable
handle to the vessel screwed out and carrying a screwed pillar, fixed to the pressing

page_text: plate, and lid, actuated by the handle in connection with said screwed pillar.
Substantially as hereinbefore described and for the purposes set forth, and shewn
on the accompanying sheet of drawings.
