PROVISIONAL SPECIFICATION..
Improvements in Scrubbing Brushes and other Brushes of a
similar kind.
I, THOMAS BARDSLEY, Butcher's Engineer, of 115, Liverpool Road, Manchester,
in the County of Lancaster, do hereby declare the nature of this invention to
be as follows::
This invention relates to improvements in scrubbing brushes, or other brushes
of a similar kind, with special reference to those wherein the tufts of bristles, or
fibre, are replaced by strips or blades of metal:
The length of said strips or blades requisite to give the pliancy or elasticity
necessary for scrubbing purposes, render them particularly liable to be bent,
twisted, or even broken, especially as regards the clusters of strips or blades on
the outer edge of the block or backing, in which they are set.
The dislocation of even one or a few of the clusters, being sufficient to seriously
impair the efficiency of the brush, and wear out the blades or strips.
My object is to strengthen the said strips or blades without in any way affecting
their pliancy or elasticity, and with this object in view, I propose to place
round the outer clusters a rim of metal, or other suitable material, extending
upwards a certain distance, or round both the outer and inner clusters.
Preferably, I take a strip of tin, or tinned iron, and first double it to the required
depth the inner side of the flange thus formed being pressed against the outer
row of clusters, whilst the outer side of the flange is flattened on the surface of the
outer edge of the block and turned tight over, and a short distance down the
side of the block, whereby a tight hold on the block is secured, and a few small
screws or nails through the metal render it perfectly fixed, and immoveable,
(though readilly removed if required).
By means of this flange of metal doubled over, whilst ample support is afforded
to the strips or blades a certain amount of elasticity in the pressure against them
is secured which is very desirable when the heavy wear and tear on these brushes
is considered.
Similar metal flanges may be placed against the other rows of strips or blades
if desired, either in the direction of the length or breadth of the block or backing.
As an alternative plan small metal tubes may be inserted in the backing
extending a sufficient distance upwards, around a cluster of strips or blades.
Dated this Sixth day of March 1899.

page_text: 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 improvements in scrubbing or other brushes of a
similar kind with special reference to those wherein the tufts of bristles or fibre,
are superseded by metal strips or blades.
The length of said strips or blades requisite to give the pliancy or elasticity
necessary for scrubbing purposes render them particularly liable to be bent,
twisted, or even broken especially as regards the clusters of strips or blades on
the outer edge of the block or backing, in which they are set, the dislocation of
even one, or a few clusters being sufficient to seriously impair the efficiency of the
brush and wear out the blades or strips.
My object is to strengthen the said strips or blades without in any way affecting
the pliancy, or elasticity, and with this object in view, I propose to place
round the outer clusters a rim of metal, or other suitable material extending
upwards a certain distance, or round both the outer and inner clusters.
Preferably, I take a strip of tinned iron and first double it to the required
depth, the inner side of the flange, thus formed, being pressed against the outer
row of clusters, while the outer edge of the flange is flattened on the surface
of the outer edge of the block, and turned tight over, and a short distance down
the side of the block, whereby a tight hold on the block is secured, and a few
small screws or nails through the metal render it perfectly fixed and immoveable
(though readilly removed if required).
Fig. 1 on the drawings, is a side elevation and Figure 2 a cross section of a
brush with metal strips or blades, constructed according to the principles of my
invention.
"a" is the brush block
"b" the cluster of strips or blades.
65 "
the metal strengthening rim.
"d" the pin or screw for fixing said rim.
By means of this flange of metal doubled over, whilst ample support is afforded
to the strips or blades, a certain amount of elasticity in the pressure against them
is secured, which is very desirable when the heavy wear and tear on these brushes
is considered.
Similar metal flanges and cross strips may be placed against the other rows of
strips, or blades if desired either in the direction of the length or breadth of the
brush block or backing.
As an alternative plan small metal tubes may be inserted in the backing
extending a sufficient distance upwards around a cluster of strips or blades.
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―
In scrubbing or other brushes, the supporting and strengthening the rows of
tufts of bristle, fibre, or metal strips, or blades, by a rim and cross strips of
metal, or other suitable material, adjusted to the brush blocks in the uanne
hereinbefore described.
