I, RICHARD CHIDLEY, of 39 Whittington Road, Wood Green, London, in the
County of Middlesex, Commission Agent, do hereby declare the nature of this
invention to be as follows:-
My improved device is intended to replace known forms of lamp glass cleaners, as
it will more efficiently clean such glasses in less time than usual, while preventing the
possibility of same being broken during the cleaning..
It consists of a central rod or tube provided with a mop or brush at or near its
upper end. Beneath such mop or brush the upper ends of one, two, three or more
flexible elastic arms or springs are secured, the lower ends of such arms being secured
to a sleeve capable of sliding up and down on the lower part of the central rod. The
sleeve carries a spring actuated lever or pawl which is normally forced into engage-
ment with teeth or depressions formed on the central rod. The extreme lower end of
the central rod is provided with a handle by which the whole may be turned. The
flexible elastic arms may be covered with felt or other suitable material, or they may
be in the form of brushes.
The operation of my improved cleaner is as follows:-
The sleeve is first brought to its lowest position on the rod, by releasing the spring
pawl and moving the sleeve downwards until the flexible arms lie nearly or quite close
to the central rod. The top mop or brush is then inserted into the glass until it
reaches the top of same. The sleeve is then forced upwards on the central rod until
the flexible spring arms fit the enlarged portion of the glass, the spring lever or pawl
maintaining the sleeve in the position to which it has been raised. The whole device
is then revolved by means of the handle at the lower end of the central rod, and the
top mop or brush and spring arms perfectly clean the glass. By releasing the spring
lever or pawl from engagement with the teeth or depressions on the central rod, the
sleeve can be moved downwards again, or the spring of the arms themselves will
effect such movement, and the device can then be removed from the glass after
cleaning.

page_text: In the case of the glass being very dirty it may be advisable to employ a properly
shaped chamois or other leather, which is placed over the mop and spring arms before
the device is inserted into the glass, so that when the arms are expanded and the
device revolved it effectually removes all adhesive matter, and when this has been
effected the leather may be removed and the polishing effected by replacing it by a
clean linen or other rag.
A stop or disc is preferably fitted to the upper end of the sleeve so as to limit the
extent to which the device is inserted into the glass.
I prefer to make the central rod of square, oval or other suitable section at the part
over which the sleeve slides, and the hole through such sleeve of corresponding form,
so as to prevent the twisting or turning of such sleeve on the rod, but this may also
be effected if desired by means of a pin and slot connection between the sleeve and
rod.

1, RICHARD CHIDLEY, of 39 Whittington Road, Wood Green, London, in the
County of Middlesex, Commission Agent, 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 :-
My improved device is intended to replace known forms of lamp glass cleaners, as
it will more efficiently clean such glasses in less time than usual, while preventing
the possibility of same being broken during the cleaning.
A suitable method of carrying the invention into effect is illustrated in Figs. 1
and 2 of the accompanying drawings, Fig. 1 being a front elevation, and Fig. 2 a side
elevation of my improved cleaner, when inserted in and moved to the position it
occupies when cleaning a glass.
It consists of a central rod or tube A provided with a mop or brush B at or near its
upper end.
Beneath such mop or brush the upper ends of one, two, three or more
flexible elastic arms or springs C, C, are secured, the lower ends of such arms being
secured to a sleeve D capable of sliding up and down on the lower part of the central
rod A. The sleeve carries a spring actuated lever or pawl E which is normally forced
into engagement with teeth or depressions F formed on the central rod Å. The
extreme lower end of the central rod A is provided with a handle A' by which the
whole may be turned. The flexible elastic arms C, C³, may be covered with felt or
other suitable material, or they may be in the form of brushes.
The operation of my improved cleaner is as follows:-
The sleeve D is first brought to its lowest position on the rod A, by releasing the
spring pawl E and moving the sleeve downwards until the flexible arms C, C, lie
nearly or quite close to the central rod, as shown by dotted lines in Fig. 1. The top
mop or brush B is then inserted into the glass G until it reaches the top of same.
The sleeve D is then forced upwards on the central rod A until the flexible spring
arms C, C, fit the enlarged portion of the glass, the spring lever or pawl E by its
engagement with the teeth F on rod A, maintaining the sleeve in the position to
which it has been raised, as shown in full lines in Fig. 1. The whole device is then
revolved by means of the handle A¹ at the lower end of the central rod A, and the top
mop or brush B and spring arms C, C³, perfectly clean the glass. By releasing the
spring lever or pawl E from engagement with the teeth or depressions F on the
central rod A, the sleeve D can be moved downwards again, or the spring of
the arms C, C, themselves will effect such movement, and the device can then be
removed from the glass after cleaning.
In the case of the glass being greasy, smoky, or otherwise dirty, it is advisable to
employ a properly shaped chamois or other leather H, which is preferably wetted, and
if the glass is greasy also soaped, such leather being placed over the mop or brush B
and the spring arms C, C, before the device is inserted into the glass, so that when
the arms C, C, are expanded and the device revolved it effectually removes all
adhesive matter, and when this has been effected the leather may be removed and the
glass be polished by replacing such leather by a clean linen or other rag, also
preferably shaped to fit the glass when the arms are expanded.

page_text: An arm I forming a stop is preferably fitted to the upper end of the sleeve D, so as
to limit the extent to which the device is inserted into the glass, such arm being
capable of folding up close to the side of the sleeve (as shown in dotted lines in
Fig. 1), in order to allow the arms, after they have been expanded, to be forced
slightly further upwards, if necessary, so as to ensure the proper contact with the
glass at the part where it becomes narrower towards the top.
I may make the central rod of square, oval, or other suitable section, at the part
over which the sleeve D slides, and the hole through such sleeve of corresponding
form, so as to prevent the twisting or turning of such sleeve on the rod, but this may
also be effected if desired by means of a pin and slot connection between the sleeve
and rod.
Suitable arrangements of such pin and slot connection are shown in Figs. 3 and 4
of the drawings, which also show different modifications of the manner in which the
invention can be carried into effect. In these Figs. the central rod A is shown as
terminating within the sleeve D, instead of extending right through same, and the
teeth or depressions F are formed on the sleeve D instead of on rod A, while the latter
carries the pawl E, instead of same being mounted on the sleeve D. The handle A¹
in both these Figs. is shown as extending through slots D¹, D³, at diametrically
opposite points in the sleeve D, and thus prevents the rod A turning in relation to the
sleeve.
In Fig. 3, one part A of the handle of the rod A, is pivotted to such rod at A',
such part A extending upwards and outwards beyond the pivot, and being shaped to
form the pawl E, which engages with the teeth F formed on the outer surface of
sleeve D. A spring K acts on the part A³ so as to normally force the pawl E to
engage with teeth F, and on pulling the rod A downwards, the pawl E will slip over
same, and thus expand the arms C, C₁. To return these arms to their closed position,
the part A is forced downwards against the action of spring K, thus releasing pawl E
from engagement with teeth F, leaving the rod A free to move upwards and thus
close the arms C, C¹.
In Fig. 4, a similar arrangement is shown to that last described, but the teeth F
are in this case formed on the inside of the sleeve D, and the part A secured to
rod A, is in the form of a spring arm which carries, or on which is formed, an
abutment or projection constituting the pawl E to engage with the teeth F.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is :-
The improved lamp glass cleaner provided with a flexible arm or arms, the upper
ends of which are secured towards the upper end of a central rod or tube, while their
lower ends are secured to a sleeve capable of sliding on the lower part of such rod or
tube, so as to enable such arm or arms to expand and bend to fit the interior of the
lamp glass to be cleaned when the sleeve is moved upwards in relation to the rod,
while enabling them to collapse and lie approximately parallel with the central rod or
tube when the sleeve is in its lowest position, whereby the cleaner can be inserted into
or removed from the glass; and either the rod or tube or the sleeve being provided
with teeth or depressions, with which a pawl is arranged to engago, for the purpose
of holding the arm or arms in their expanded position, all substantially as described
and shown.
