THOMAS MARSHALL of 8 Bridge Terrace, Lower Woolwich Road, East Greenwich
in the County of Kent. "IMPROVED APPLIANCE TO FACILITATE CLEANSING THE
INSIDE SURFACE OF FLEXIBLE AND ELASTIC TUBES USED WITH FEEDING
BOTTLES.
وو
This Invention relates to an appliance capable of being inserted into a flexible
and elastic tube used with a feeding bottle, the tube being drawn over the appliance
which is provided with one or more discs or swellings with a scraping edge and of
slightly larger diameter than the interior of the tube to remove any deposit which
may have adhered to it.
For the purpose of my Invention I preferably twist a doubled wire to form a
loop at the end which serves to lace or thread the end of the tube into the stopper
to replace it in position.. The opposite end of the twisted wire has affixed to it
one or more discs, ferrules or sockets having a scraping edge or edges slightly
larger in diameter than the interior of the tube it is intended to clean by a
scraping action.
In some cases I affix a piece of sponge or other absorbent on the end of or to the
disc, ferrule or socket to dry the interior or to remove any particles of impurity
which may have escaped the disc.

by the said Thomas Marshall in the Great Seal Patent Office on the
8th September 1882.
THOMAS MARSHALL of 8 Bridge Terrace, Lower Woolwich Road, East Greenwich
in the County of Kent IMPROVED APPLIANCE TO FACILITATE CLEANSING THE
INSIDE SURFACE OF FLEXIBLE AND ELASTIC TUBES USED WITH FEEDING
BOTTLES.
This Invention relates to an appliance capable of being inserted into a flexible
and elastic tube used with a feeding bottle the appliance being pushed into and
drawn through the tube.
The appliance is provided with one or more discs or swellings with a scraping
edge and of slightly larger diameter than the interior of the tube to remove any
deposit which may have adhered to it.
For the purpose of my Invention I preferably twist say two wires or a double
wire to form a stem, a loop being shaped at one end which serves to lace or thread
the end of the tube into the stopper which fits the mouth of a feeding bottle when
the stopper has to be replaced in position. The opposite end of the twisted wire
or stem has affixed to it a disc, ferrule, socket or swelling having a scraping edge
or edges slightly larger in diameter than the interior of the tube it is intended to
clean by a scraping action, said swelling with the scraping edge may be formed
from the same material as the stem.
In some cases I affix a piece of sponge or other absorbent on the end of or to the
disc, swelling, ferrule, or socket to dry the interior or to remove any particles of
impurity which may have escaped the scraper.
The appliance is represented at Figure 1 of the annexed Drawings and its action
will be understood by Figure 2 A is a head, swelling, a ferrule with an edge
shaped projection B for scraping the internal surface of the india rubber elastic
tube C when drawn through it. The edge shaped projection B is of slightly larger
diameter than that of the tube C so as to expand the tube C as at E Figure 2
to thoroughly scrape the interior and remove all impurities which may have
adhered to it.
The head, swelling or ferrule A. is attached to the ends of a double wire F
twisted, or to a plain stem as at Figure 3, the opposite or loop end G serving to
draw the head through the tube by the hand, and also to lace the tube C into the
stopper of a feeding bottle to replace it. The cleansing by a scraping action is
expedited by first steeping the india rubber tube in water.
Figure 4 represents a modification of the head A, this having three scraping
edges. Figure 5 shows the scraping edges B B as formed of screw like thread on
the body of the head or ferrule A, said screw like thread may be formed by
twisting the wire as at Figure 6. Figures 7 and 8 show other modifications of the
head or swelling A, a piece of sponge or other absorbent of moisture H being fixed
on the head to follow the scraping in order to remove any particles of impurities
that may have escaped past the scraper edge B.
Having now described the nature of my said Invention and in what manner the
same is to be performed I declare that I claim :-
The appliance shown in the annexed drawings for cleansing by a scraping

described.
In witness whereof I the said Thomas Marshall have hereunto set my hand
and seal this Sixth day of September, in the year of our Lord, One
thousand eight hundred and eighty two.
