MAURICE MOCRAINOR, Engineer 7 South Garden St. Bury, Lan JOHN CLEGG
Engineer 8 Manchester Road, Fishpool, Bury Lancashire do hereby declare the
nature of our invention for AN EXPANSION BRUSH OR APPARATUS FOR CLEANING
THE INSIDE OF ROUND BOTTLES to be as follows:-
The Expanding brush is made of a round brass tube, bored & turned, with a boss
at one end to admit a sliding collar which works in a groove cut in each side of
the boss in the inside of this brass tube is fixed a steel spindle At one end of
this steel spindle is fixed an apparatus which carries the bristles of the brush &
which is so made that it can be opened or closed at pleasure by working the collar
before mentioned. To insert the apparatus into the bottle the brass collar is pushed
down on the brass tube so that the bristles lie close to the tube-It is then inserted
into the neck of the bottle & then the sliding collar is pushed back & the apparatus
opens so that the bristles of the brush come in contact with the whole of the inside
surface of the bottle-the other end of the spindle being fixed in the headstock of
the machine the machine is set in motion & the brush revolves in the bottle &
thorougly cleans the bottle in every part-The apparatus is so constructed that
the bottles can be put on & cleaned & taken off without stopping the brush-When
the brush has been inserted into the bottle it is kept in position by means of a
catch which is fitted into the boss of the tube & which is worked by a tappet
connected with a sliding collar.
The brush can be made to suit any size of bottle & also to suit any exsisting
headstock.

MAURICE MOORAINOR of 21 Walmersley Road (formerly 7 South Garden St.)
Bury, Lan Engineer, & JOHN CLEGG, 8 Manchester Road Fishpool, Bury, Lan
Engineer, do hereby declare the nature of our invention for AN EXPANSION BRUSH
OR APPARATUS FOR CLEANING THE INSIDE OF ROUND BOTTLES and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:—
The apparatus consists of a brass or other metal tube (brass preferred) accurately
bored out & with a slot cut in at one end for the reception of the segments carrying
the bristles when the brush is closed. The said segments are connected to the brass
tube near its end by a loose joint at the bottom of the slot & are likewise connected
with a steel spindle that runs through the centre of the brass tube. On this steel
spindle and at the opposite end of the brass tube to that which is joined to the
segments, is fixed an open spiral spring.
When the bottle has been placed on the brush the pressure of its bottom against
the end of the brass tube forces the tube backwards on the steel spindle causing the
segments to open out so that the bristles come in contact with the inside surface of
the bottle touching & cleaning it instantly in every part as it revolves. The
spiral spring before mentioned which has been forced back or closed by the pressure
of the sliding tube against it, will, when the pressure ceases, open out again &
force back the tube to its original position thereby closing the brush so as to enable
the bottle to be drawn off. To guard the spring against damage by too violent
pressure against it there is a small key driven through the stationery steel spindle,
& the head of this key which works in a slot cut into the sliding tube arrests the
motion of the tube at the proper moment both in opening & shutting. To prevent
'any objectionable matter getting into the slot to interfere with the working it is
covered by a small ferrule secured by a set screw.
At the bottom of the slot which receives the segments is fixed a spring which
facilitates the opening of the brush inasmuch as it keeps the joints of the segments
in a rising position.
The Brush is so adapted that it can be fixed in the headstock of any machine
that will give it rotary motion.
