PROVISIONAL SPECIFICATION.
Improvements in and connected with Brushes for Cycle, Motor Car
and the like Chains.
We, EDWIN LEE, of 17, Churchbank, Boot and Shoe Manufacturer, and JOSEPII
LINGARD, of 9, Earl Street, Great Lever, Shop Manager, both of Bolton, in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved form of brush for cycle, motor car
and the like chains, which besides keeping the chain cleaner serves also to retain
the chain at a suitable tension as well as to guard the same and in case of cycles
acts as a brake when back-peddling.
To this end our invention consists in providing for the said purposes a circular
brush, adapted to be rotated by the said chain which brush by preference we
employ to run in contact with the inner side of the chain.
According to one form of our invention in which it may be carried out we mount
the said rotary brush upon a pin carried by an arm which at its opposite end is
formed in clip fashion to allow of being secured in or about the middle of the
stay running from the crank axle bearing to the back fork in case of a cycle
or in an equivalent position in a motor car.
If deemed necessary the said arm may be adapted to be lengthened or shortened
so as to cause the brush to tension or grip the chain more or less as may be
required.
According to another form of our invention the said arm may be extended
upwards and around the top of the chain so as to serve also as a guard for the
upper part of the chain.
By providing the said brush with a suitable handle it may be applied to the
chain by one hand, whilst the chain, through the medium of the back wheel
or crank, is turned by the other.

COMPLETE SPECIFICATION.
Improvements in and connected with Brushes for Cycle, Motor Car
and the like Chains.
We, EDWIN LEE, of 17, Churchbank, Boot and Shoe Manufacturer, and JOSEPH
LINGARD, of 9, Earl Street, Great Lever, Shop Manager, both of Bolton, in the
County of Lancaster, 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:-
:-
This invention relates to an improved form of brush for cycle, motor car
and the like chains, which besides keeping the chain cleaner serves also to retain
the chain at a suitable tension as well as to guard the same and in case of cycles
acts as a brake when back-peddling.

page_text: And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Figs. 1 & 3 being side views and
Figs. 2 & 4 sectional end views respectively of two different forms in which our
combined brush and chain guard may be carried out.
According to one form of our invention and referring to Figs 1 & 2, we mount
a rotary brush a upon a pin b carried by a forked arm or bracket c formed at its
opposite end with a clip d to allow of being.secured in or about the middle of
the back stay e, or in an equivalent position in a motor car as will be readily
understood.
The said arm or bracket is preferably formed in one piece of a strip of metal
and being forked, firmly supports and guides the rotary brush and chain at each
side whilst the strength thereby obtained allows the brush to act on the chain
as brake when back peddling.
If deemed necessary the arm or bracket c may be adapted to be lengthened or
shortened or formed with a number of holes f so as to permit of adjusting the
brush for tensioning or gripping the chain more or less and accommodating the
various sizes of chain wheels used as may be required.
According to another form of our invention and referring to Figs. 3 & 4, the
arn or bracket c may be extended upwards and around the upper path of the
chain g so as to guard each side of the chain at the upper path and thus prevent
the chain from running out of line whilst it also serves as a guard for the clothing
of the rider.
As will be seen from the drawing the rotary brush a is arranged to run only
slightly in contact with the inner side of the chain at its lower path, so as to
offer practically no resistance when forward peddling, whilst when back peddling,
the chain tightening against the brush, see dotted lines, the brush is caused to act
on the chain as a brake and at the same time thoroughly cleanse the same.
To facilitate also the cleansing of the outer sides of the chain we may provide
the bent or upper end of the arm or bracket c with a stationary brush h, as shown
in Figs. 3 & 4, between which the chain g runs.
By providing the said rotary brush with a suitable handle it may be applied
to the chain by one hand, whilst the chain, through the medium of the back wheel
or crank, is turned by the other.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim, is-
1st. A cycle or the like rotary chain brush, chain guard, and brake combined
constructed and operating all substantially as set forth.
2nd. A rotary brush and guard combined for cycle and the like chains, con-
sisting of a forked arm or bracket c adapted to be clipped to the back stay and
the lower end of which carries a rotary brush adapted to simultaneously clean
and act as a brake on the chain when back peddling, all substantially as set forth.
3rd. In a cycle and the like chain brush such as specified in the preceding
claim, the arm or bracket & extended round the upper path of the chain, so as to
form a guard for the chain at its top path at each side, all substantially as set
forth.
4th. The arm or bracket specified in the preceding claim furnished at its upper
end with a stationary brush, all substantially as set forth.
