PROVISIONAL SPECIFICATION.
Improvements in and relating to Brushes for use in Machines for
Cleaning Lamp Gauzes, Glasses, and the like.
I, ANDREW HOWAT, of 6 Bellwood Terrace, Old Trafford, Manchester, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to improvements in and relating to brushes for use in
machines for cleaning lamp gauzes glasses and the like, such brushes being particu-
larly applicable for use in the safety lamp cleaning machine for which I obtained.
Letters Patent No. 10407 of 1888.
I have found in practice that the end bristles of these brushes soon get worn
away while the bristles on the body of the brush last good much longer and the
chief object of my present improvements is to enable the end bristles to be renewed
without interfering with the remaining portion of the brush.
In constructing my improved brush I take a hollow metal stock into which 1
insert a filling piece of wood or other suitable material. I then drill holes through
the metal and into the filling piece into which I insert the bunches of bristles the
holes being preferably so drilled that the bristles are arranged spirally around the
stock. One end of the brush is screwed or otherwise prepared for connection as
usual to the rotating spindle upon which it is mounted but the other end of the
brush is made in the form of a detachable cap into which the bristles forming the
end of the brush are secured and when these get worn out the cap can be detached
from the stock the worn stumps removed and replaced by new bristles.
In order to prevent injury to the end bristles of the brush when applied to my
aforesaid lamp cleaning machine or in other cases where found advantageous or
desirable I secure an adjustable collar upon the base or screwed end of the brush
spindle. This collar prevents the lamp gauze from being pushed too far forward on
to the brush and consequent injury to the end bristles.

Improvements in and relating to Brushes for use in Machines for
Cleaning Lamp Gauzes, Glasses, and the like.
1, ANDREW HOWAT, of 6 Bellwood Terrace, Old Trafford, Manchester, in the
County of Lancaster, Engineer, 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 invention relates to improvements in and relating to brushes for use in
machines for cleaning lamp gauzes glasses and the like, such brushes being particu-
larly applicable for use in the safety lamp cleaning machine for which
Letters Patent No. 10407 of 1888.
obtained.
I have found in practice that the end bristles of these brushes soon get worn
away while the bristles on the body of the brush last good much longer and the
chief object of my present improvements is to enable the end bristles to be renewed
without interfering with the remaining portion of the brush.
In constructing my improved brush I take a hollow metal stock into which I
insert a filling piece of wood or other suitable material. I then drill holes through

page_text: the metal and into the filling piece into which I insert the bunches of bristles the
holes being preferably so drilled that the bristles are arranged spirally around the
stock. One end of the brush is screwed or otherwise prepared for connection as
usual to the rotating spindle upon which it is mounted but the other end of the
brush is made in the form of a detachable cap into which the bristles forming
the end of the brush are secured and when these get worn out the cap can be
detached from the stock the worn stumps removed and replaced by new bristles.
In order to prevent injury to the end bristles of the brush when applied to my
aforesaid lamp cleaning machine or in other cases where found advantageous or
desirable I secure an adjustable collar upon the base or screwed end of the brush
spindle. This collar prevents the lamp gauze from being pushed too far forward
on to the brush and consequent injury to the end bristles.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Fig. 1 is a side view Fig. 2 a similar view in section of a brush made according
to my invention for use in machines for cleaning lamp gauzes glasses and the
like and Figs. 3 and 4 represent the end portion of the brush in full and in section.
In Figs. 1 and 2, a is the hollow metal stock of the brush enlarged at a¹ and
provided with an internal screw thread for screwing on to the rotating spindle
upon which it is to be mounted; the hollow stock a is filled with a piece of wood or
other suitable material into which the bristles c are fastened, the end a² of the
stock is threaded to receive a cap or end piece d; which can be readily removed
and changed as desired; the pièce d is also filled with wood or other material e to
receive bristles f.
g
Fitted on the part a¹ of the hollow stock is an adjustable collar
secured in any
desired position by a set screw h; in Figs. 1 and 2 the collar is set close up to the
bristles and forms a stop piece to prevent the lamp gauze to be cleaned from being
forced too hard against the end bristles f and destroy them as these bristles wear
the screw can be slackened and the collar g moved back as far as required along a¹
and then secured by its set screw h.
When the bristles fare too far worn for cleaning lamp gauzes and the like the
end piece d is removed and fresh bristles inserted or a new end piece can be fitted
on to the stock a.
In place of the screw thread at a² any other means for securing the piece d to
the metal stock may be employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :--
1. The improved brush for cleaning lamp gauzes, glasses and the like, consisting
of a metal stock provided with a removable piece to carry the end bristles sub-
stantially as and for the purposes described.
2. The use and application of an adjustable collar such as g or its equivalent
arranged to protect the end bristles of a rotating brush for cleaning lamp gauzes
glasses and the like as and for the purposes described.
