I ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention (a communication from
George P. Goulding of Rochester, New York, United States of America, Brewer)
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 certain improvements in brushes for bottle washers
designed more particularly for use in connection with the bottle-washing machines
described in the previous patent N° 8149 of 1884 but capable of being employed
in other machines. The improvements are fully described in the following specifi-
cation, and the novel features thereof specified in the claims thereunto annexed.
In the accompanying drawings representing the improvements in brushes for
bottle washing machines.
Figure 1 is a side view.
Figure 2 is an end view.
Figure 3 is a longitudinal section.
Figure 4 is a transverse section on the line x x Figure 3.
In the accompanying drawings A represents a metallic tube or thimble by which
the brush B is attached to the revolving spindle of a bottle washing machine-the
thimble being provided with internal threads at either end as shown in the
sectional view Figure 3 for the insertion of the brush in the thimble and
the attachment of the thimble to the spindle.
The brush B consists of an india-rubber rod of suitable section divided
longitudinally as indicated at 8 so that the divided parts may expand as shown
by the dotted lines Figure 1 from the action of centrifugal force when the
brush is caused to revolve rapidly and provided with an axial perforation at the
end which is inserted in the thimble, through which a current of water is designed
to be discharged into the bottle during the operation of washing its interior.
The object of making the rod solid throughout its divided portion is to secure as
great weight as possible in the strips r so as to cause them to expand with the
greatest force against the interior of the bottle. The exterior surface of the strips
is also preferably corrugated at an angle with the longitudinal axis of the brush as
indicated at f in the drawings Figure 1 so as to increase the efficiency of the
Scouring or cleaning action of the brush on the inner surface of the bottle. The
brush is conveniently made by being vulcanized in one piece with the hole in its

page_text: inner end-The solid part being subsequently divided with a suitable cutting
instrument. In order to strengthen the brush at the end which is attached to the
thimble I insert in it during the vulcanizing process, one or more layers of strong
cloth or canvas e.
In order to secure the firm attachment of the brush to the thimble, I insert into
the axial perforation in the brush, the tube C and fasten the brush and tube in
place in the thimble by means of the screw or pin d which is smaller than the
opening in the tube C as shown in the sectional view Figure 4 so as not to interfere
with the discharge of a sufficient quantity of water through the tube. The thimble
is preferably threaded internally and the brush screwed into it, being thereby
compressed and more securely fastened therein.
This improved brush for bottle washing machines is cheap in construction,
exceedingly durable and highly efficient in operation-being capable of doing.
faster and better work than any other device for the purpose which has been
hitherto proposed.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is:
1. The combination with the scraper or brush consisting of the rod or cylinder
of rubber divided longitudinally for a portion of its length and provided at one
end with a recess or socket of the cloth or canvas tube secured to the brush around
the, socket for strengthening it substantially as described.
2. The herein described scraper or brush consisting of the rod or cylinder of
rubber recessed for a portion of its length and split longitudinally for the remainder
provided on its exterior surface with the corrugations or ribs arranged at an angle'
to the longitudinal axis of the brush substantially as described.
3. The combination with the scraper or brush consisting of the rod or cylinder
of rubber having a socket at one end and split longitudinally for the remainder of
its length, of the inner tube placed within the socket and the revolving spindle to
which the inner tube is adapted to be secured, substantially as described.
4. The combination with the .hollow spindle A and the scraper or brush
consisting of the rod or cylinder having the socket at one end and split longitu-
dinally for the remainder of its length of the canvas or cloth secured to the rubber
around the socket substantially as described.
. .
5. The combination with the hollow spindle A and the scraper or brush having
the socket at one end and split longitudinally as described of the canvas or cloth
secured to the rubber around the socket and the inner tube placed within the
socket and secured to the spindle substantially, as described.
6. The combination with the longitudinally divided revolving india-rubber brush
or scraper B of the revolving hollow-spindle A inner tube C canvas e and pin d
substantially, as described.
7. The improved brush for cleaning. the interior of bottles consisting essentially
of the rod of rubber or equivalent flexible material formed with a longitudinal
passage at one end and provided. at the other end with a series of flexible rods or
sections overlapping and partially closing the inner end of the passage for the
cleansing fluid when said rods or sections are brought together, substantially as
described.
