Improvements in or in connection with Metal or other Boxes or
Holders for Containing and Delivering Laundry Blue or the like
or other Material in Suitable Quantities.
JOHANN OTTO EGESTORFF of 331 Camden Road, Camden Town, London,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to boxes devices or holders for containing and delivering
various materials particularly for such purposes as holding and delivering soluble
material which is required to be intermittently discharged into or mixed with
water such for instance as laundry blue either in the solid block form or as a
powder or flour-my present invention being designed to provide a device or
appliance (for immersion in the liquid to be impregnated colored or infused) by
which such discharge can be readily effected and regulated and when out of use
such appliance according to my present invention will not permit escape or leakage
of the material until the next immersion thereof in the water and furthermore
same is very simple in use and economical to produce and has many advantages
over other appliances or devices heretofore in use or designed for a similar
purpose.
My present invention is as follows:-
I form or use a vessel box or holder of any suitable size shape and material or
materials advantageously a small drum or circular can of thin sheet metal such as
tin plate and I leave or form or arrange an aperture or apertures either at one end
or any other convenient part or parts of the said box or vessel as desired and
over this aperture or apertures or under same or adjacent thereto i arrange and
mount in any suitable manner a diaphragm (without any hole through same) or
sheet or piece or pieces of material advantageously elastic such as thin sheet india
rubber or imitation or equivalent thereof so that same can be pushed or pressed
(or pulled or raised) by the hand or finger or thumb of the operator (direct or
otherwise) to thus compress or force same inwards (or outwards) and on releasing
same it will naturally (if elastic) return to its normal position or (if non-elastic
or non-resilient) same may be forced in both directions.
Opposite this diaphragm or compressible or extensible part for instance in the
other end of the can or holder or any other convenient part or parts thereof
I arrange or provide an aperture or apertures advantageously covered by or having
a piece or pieces of flannel or textile or other suitable material stretched across
same or a grating gauze or reticulated material or it may be a series of fine perforations
or other suitable arrangement to prevent the contents escaping too quickly as
desired.
For instance the box may be constructed as follows:
Before the end of the box is seamed or crimped on in the usual or any suitable
inanner with sheet metal cans a sheet of rubber is laid in between the metal lid
and the bottom edge of the side of the can (a suitable hole large enough for the
thumb or finger to pass through being provided in the lid) and then when the lid
is crimped or seamed on the elastic material is thereby firmly secured all round
the edge thus making a watertight joint or sufficiently watertight for my purpose—
the opposite end of the can being provided with a discharge opening or openings
protected or not (as desired) as aforesaid.

page_text: The blue or other desired material (having been first placed in the can before
attaching the ends thereon) upon immersing the can in the tub or water to be
colored or infused and then alternately pressing and releasing the aforesaid diaphragm
thereby a kind of pumping action is set up inside the can that is to say water is first
expelled from the can and then drawn into same and then expelled and so on thus
causing a rapid circulation or flow of water into and out of the can and thus as much
blue etc. is discharged as desired whereupon the can is removed out of the water and
stood with the said diaphragm downmost consequently no liquid or blue etc. will
escape, and same is all ready for immediate use again when required.
If desired a swivel or other cap or cover may be arranged or mounted on either or
both ends of the box or other part thereof to close or protect the contents when out
of use.
Instead of using the elastic substance in a diaphragm or flat form as before
described I may use or apply same in any other suitable manner to cause alternate
suction and compression within the box to thus alternately draw in and expel the
water for instance a small ball or nipple or equivalent (acting after the manner of
those on the well known enemas etc.) on the exterior of the box and connecting with
the interior of the box by a short pipe or other suitable connection.

Improvements in or in connection with Metal or other Boxes or
Holders for Containing and Delivering Laundry Blue or the like
or other Material in Suitable Quantities.
I JOHANN OTTO EGESTORFF of 331 Camden Road, Camden Town, London,
Merchant 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 relates to boxes devices or holders for containing and delivering
various materials particularly for such purpose as holding and delivering soluble
material which is required to be intermittently discharged into or mixed with water
such for instance as laundry blue either in the solid block form or as a powder or
flour-ny present invention being designed to provide a device or appliance (for
immersion in the liquid to le impregnated coloured or infused) by which such
discharge can be readily effected and regulated and when out of use such appliance
according to my present invention will not permit escape or leakage of the material
until the next immersion thereof in the water and furthermore same is very simple in
use and economical to produce and has many advantages over other appliances or
devices heretofore in use or designed for a similar purpose.
My present invention as follows:
I form or use a vessel box or holder of any suitable size shape and material or
materials advantageously a small drum or circular can of thin sheet metal such as tin
plate and I leave or form or arrange an aperture or apertures either at one end or
any other convenient part or parts of the said box or vessel as desired and over this
aperture or apertures or under same or adjacent thereto 1 arrange and mount in any
suitable manner a non-porous diaphragm or waterproof sheet or piece or pieces of
elastic material advantageously such as thin sheet india rubber or imitation or
equivalent thereof so that same can be pushed or pressed (or pulled or raised) by the
hand or finger or thumb of the operator (direct or otherwise) to thus compress or

page_text: force same inwards (or outwards) and on releasing same it will naturally being elastic
return to its normal position.
In the other end of the can or holder or in any other convenient part or parts
thereof 1 arrange or provide an aperture or apertures advantageously covered by or
having a piece or pieces of flannel or textile fabric or other suitable porous material
stretched across same or a grating gauze or reticulated material or it may be a series
of fine perforations or other suitable arrangement as desired to prevent the contents
escaping too quickly.
If desired a swivel or removable or other suitable cap or cover may be arranged or
mounted on either or both ends of the box or other part thereof to close or protect.
the contents when out of use.
.
And in order that my present invention may be the more easily understood I will
proceed to describe same with reference to the drawings hereunto annexed.
Fig. 1 is a plan view of the top or discharge end of a metal box or case according
to my present invention.
Fig. 2 is a plan of the opposite or bottom end of said box.
Fig. 3 is a vertical sectional view on line 1-2 Figs. 1 and 2 of said box filled with
laundry blue in the well known powder form.
A is drum or body (advantageously formed of thin sheet metal such as tin plate
and of circular or other suitable shape) forming the side of the case and having the
top B and bottom C each of similar sheet metal (or other suitable inaterial) respec-
tively secured thereon in any suitable manner such as is well known in securing on
the tops and bottoms of tin cans of various kinds for instance same may advantageously
be simply "crimped or seamed on with a "single" or "double" seaming-
machine."
"
"
<
The top B has an opening B¹ provided therein for permitting the discharge there-
through of the contents of the box and moreover is advantageously made to slope
downwardly and inwardly at B2 see Fig. 3 so that when stood as in Fig. 3 after each
immersion same will drain into the interior of the box.
This aperture B' is provided with a suitable cover grid strainer or material to
prevent the contents of the box dropping out or too freely coming out and this
cover X may advantageously consist of a piece of flannel or other like textile secured
right across said aperture B₁ to act as a strainer and said cover X can be mounted
and secured in position by being laid in between the top B and the side A before the
former is "seamed" on to the latter.
The bottom C (attached to the side A as aforesaid) has an opening C₁ therein large
enough to admit the thumb or finger.
Over this aperture is stretched a partition or diaphragm Z of elastic waterproof
material advantageously thin sheet india-rubber or imitation or equivalent thereof and
this sheet of india-rubber or elastic diaphragm Z may be secured in position in any
suitable manner over said aperture C¹ for instance same may be secured by laying it
in between the bottom and the side A of the box before seaming them together so
that when the bottom C has been seamed on to the side A thereby the rubber Z will
be firmly held all round in said seam (in a similar manner to the flannel X) and
consequently make a watertight joint so that no leakage or escape can take place
either through the said bottom aperture C¹ see Fig. 3 or round the edge where said
bottom C is secured on to A.
Y is the blue shown in powder form in Fig. 3-or same may be in block or
other suitable form as desired.
The operation is as follows:-
On immersing the box containing the blue etc. in the water to be coloured and
placing the finger or thumb on the diaphragm Z and alternately pressing and
releasing this elastic diaphragm thereby the water will be alternately forced out of
and drawn into the box through the aperture B₁ and this is continued until
sufficient blue has been thereby expelled whereupon the box is lifted out of the
water (drained if desired) and then stood on its bottom C until more blue is again
required to be discharged.
