We WILLIAM BARTHOLOMEW of Belton Lodge The Grove Clapham Road in the
County of Surrey Engineer and EDMUND BRADLEY BAKER of N° 59 Norfolk
Street Sheffield in the County of York Manufacturer do hereby declare the nature
of our invention for "IMPROVEMENTS IN APPARATUS TO BE USED IN CONNECTION
WITH BOTTLES AND LIKE RECEPTACLES FOR THE DELIVERY OF REGULATED
QUANTITIES OF ANY POWDER OR SUFFICIENTLY DIVIDED MATERIAL," to be as
follows:-
This invention has for its object Improvements in apparatus to be used in
connection with bottles and like receptacles for the delivery of measured or
regulated quantities of any powder or sufficiently divided material.
For this purpose a tube is fitted to the mouth of the bottle or receptacle to
descend nearly to the bottom and a cover preferably of cup like form is arranged
at the lower end of the tube. The cover has a stem projecting upwards into the
tube.
When the bottle or receptacle is upright the cover or cup falls to the bottom and
a certain quantity of the powder or material enters, between the lower end of the
tube and its cover. When the bottle is inverted this portion of the powder or
material falls through the tube and is delivered at the mouth of the bottle or
receptacle whilst the cover closing against the end of the tube prevents more
following however much the vessel may contain.
The tube is by preference conical in order that it may more readily deliver the
powder or material. The tube receives a stopper to close the vessel or receptacle
when not in use.
The tube may be provided with an inverted flange embracing the neck of the
bottle or receptacle from which the tube may readily be removed when required
for filling or otherwise.
The stem with which the cover is provided serves both as a guide and also as a
stirrer to cause the powder or material to move and to descend the tube freely
when the bottle or receptacle is inverted.
Where nicety of measurement is not required the apparatus may be employed.
without the cup like cover and stem.

Bottles and like Receptacles for the Delivery of Regulated
Quantities of any Powder or sufficiently Divided Material.
We WILLIAM BARTHOLOMEW of Belton Lodge The Grove Clapham Road in the
County of Surrey Engineer and EDMUND BRADLEY BAKER of 59 Norfolk Street
Sheffield Manufacturer 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 has for its object improvements in apparatus to be used in
connection with bottles and like receptacles for the delivery of regulated quantities
of any powder or sufficiently divided material.
For this purpose a tube is fitted to the mouth of the bottle or receptacle to
descend nearly to the bottom and a cover preferably of cup like form is arranged
at the lower end of the tube. The cover or cup has a stem projecting upwards
into the tube.
-
When the bottle or receptacle is upright the cover or cup falls to the bottom and
a certain quantity of the powder or material enters between the lower end of the
tube and its cover. When the bottle is inverted this portion of the powder or
material falls through the tube and is delivered at the mouth of the bottle or
receptacle whilst the cover closing against the end of the tube prevents more
following however much the vessel may contain.
The tube is by preference conical in order that it may more readily deliver the
powder or material.
The tube receives a stopper to close the vessel or receptacle when not in use.
The tube may be provided with an inverted flange embracing the neck of the
bottle or receptacle from which the tube may readily be removed when required
for filling or otherwise.
J
.
The tube may be made fast with the bottle or receptacle and of the same
material, viz, of glass, earthenware, metal or other material. In such case the
bottle or receptacle may for convenience be filled at. the lower end, the bottom of
the bottle or receptacle forming a cork or stopper to shut in the powder.
The stem with which the cover is provided serves both as a guide and also as a
stirrer to cause the powder or material to move and to descend the tube freely
when the bottle or receptacle is inverted.
u
In order that our said invention may be most fully understood and readily
carried into effect we will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Gulf. JC."
Figure 1 is an elevation of a bottle with our improvements applied.

page_text: Figure 6 shows the same bottle inverted to deliver a measured or regulated
quantity of its contents.
a a are the sides of the bottle, b is the tube, preferably taper and usually of
metal; it may be electro plated. 61 is the inverted flange on the tube b fitting to
the neck of the bottle.
c is a semi-globular cup or cover also of metal and provided with a stem c¹. d is
the stopper of metal or other material..
In Figures 5 and 6 where the tube is made of a piece with the bottle there is a
filling hole at the bottom and a plug or stopper e closes this hole.
The cup c is considerably larger in diameter than the end of the tube b so that
it may be free to play being only controlled by its stem which is retained by the
tube.
When the bottle is inverted the cup or cover falls to its place on the end of the
tube as it is shown in Figure 6.
The tube b is not liable to become choked even if the powder or material be
somewhat adhesive, the taper form of the tube and the freely moving stem c² both
tend to keep the tube clear.
The quantity of material delivered each time that the bottle is inverted depends
on the size of the lower end of the tube b and the distance that the cup or cover c
is allowed to fall away from it when the bottle is upright. When the bottle is
upright the space directly beneath the end of the tube and between it and the
cup or cover becomes filled with the powder or material; it is this quantity
approximately which is delivered when the bottle is next inverted.
The apparatus can be used without the cup or cover.
The apparatus is particularly suitable for table use, for serving salt, cayenne
pepper, sugar and the like; it is also useful to chemists for supplying measured or
regulated quantities of various salts and other solids. It may also be made of
larger size for the use of grocers and others and may be adjusted to deliver say an
ounce, a quarter of a pound or even more. The use of this apparatus will be
found convenient and to save time even in cases where for greater accuracy
weighing is also requisite.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
(1.) A bottle or other receptacle provided with a delivery tube and a cover to
the inner end of the tube which falls away when the bottle is erect admitting
material between the end of the tube and the cover and when the bottle is inverted
seats itself on the end of the tube the portion of the material between the tube
and cover first being delivered substantially as described.
(2.) The combination of the bottle or receptacle a the tube b and cup or cover c
with its stem c¹ substantially as described.
(3.) Apparatus substantially as described and represented in the annexed
drawings.
