"Certain Improvements in or connected with Polishing Mops."
We, JOSIAH COOPER, and FRANCIS GEORGE BENSLY, trading together as Cooper
& Co., of Felt Works, Little King Street, in the City of Birmingham, Felt Manu-
facturers, do hereby declare the nature of this Invention to be as follows:
This Invention consists of the herein described improvements in or connected
with polishing mops. At the present time polishing mops are usually constructed
of discs of calico or leather or felt or other suitable material secured together side
by side between two stout central leather washers one at each side of the mop the
said washers and the material of the mop being fixed together by nails passing
through the washers and material of the mop with their ends clenched over.
polishing mop is screwed on to its revolving spindle but constant wear and drag
on the mop enlarges the central hole in the leather washers so that the polishing
mop sometimes works up the spindle off the screwed part of the same and then
slips round on the spindle or does not run true.
The
-
This defect we overcome by this Invention, which is carried out as follows:-
We provide on each or on one of the two outside faces of the polishing mop
(instead of or in addition to the leather washers aforesaid) two discs made of lead
or other soft material or alloy which are fixed to the sides of the mop preferably
by wire nails driven through holes in the leaden or other metallic disc on one
side and through the mop and through corresponding holes in the leather washer
or in the leaden or other metal disc on the other side, the ends of the nails being
clenched over so as to keep the parts together. The central hole in the leaden or
other metal disc is by preference counter-sunk to about the same taper as is the
screwed end of the polishing spindle so as to readily screw thereon.
When the mop is screwed on to the spindle the latter (being of harder metal
than the leaden or other metal disc or discs) forms the necessary thread in the
disc and the latter is stout enough to prevent the drag on the mop enlarging the
hole and the mop working too far up the spindle.
Moreover, when the mop is unscrewed from the spindle and again screwed
thereon it will come into its original position relatively to the spindle and run
true thereon.
The said leaden discs are by preference recessed on their outer faces so as to
lighten the same and made with a flange or beading round the periphery and
round the central hole and with a thickened bead round the nail holes so as to
obtain strength and lightness combined.

We, JOSIAH COOPER, and FRANCIS GEORGE BENSLY, trading together as Cooper
& Co., of Felt Works, Little King Street, in the City of Birmingham, Felt Manu-
facturers, 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 consists of the herein described improvements in or connected
with polishing mops. At the present time polishing mops are usually constructed
of discs of calico or leather or felt or other suitable material secured together side
by side between two stout central leather washers one at each side of the mop
the said washers and the material of the mop being fixed together by nails passing
through the washers and the material of the mop with their ends clenched over.
The polishing mop is screwed on to its revolving spindle but constant wear and
drag on the mop enlarges the central hole in the leather washers so that the polish-
ing mop sometimes works up the spindle off the screwed part of the same and then
slips round on the spindle or does not run true. This defect we overcome by this
Invention which we carry out as we will now describe by referring to the accom-
panying drawing on which Fig. 1 is a cross section of a polishing mop constructed
in accordance with this Invention; Fig. 2 is a back view and Fig. 3 is a front
view of the same. In Figs. 1, 2 and 3 the polishing mop is represented as partly
broken away. Fig. 4 shews separately in side elevation the leaden or other soft
metal disc of the polishing mop the said disc forming one part of this Invention:
Fig. 5 is a sectional elevation and Fig. 6 is a front elevation of the said disc and
Fig. 7 is a side elevation of the end portion of an ordinary polishing mop spindle on
to which the polishing mop shewn by Figs. 1, 2 and 3 is required to be screwed.
The same letters of reference indicate the same or corresponding parts in all
the Figures of the drawing.
In carrying out this Invention we provide on one of the outside faces of the
polishing mop A (instead of or in addition to the usual leather washers) a disc B
ishewn separately by Figs. 4, 5 and 6 made of lead or other soft metal or alloy
which disc is fixed to the side of the mop by wire nails C₁ C3 C3 C driven through
holes bbb3b in the leaden or other metallic disc B and through the mop A and
through corresponding holes in the usual leather washer D on the other side of the
mop A the pointed ends of the nails being clenched over in the usual way
(see Fig. 3) so as to keep the parts together. Corresponding with the central
hole a of the mop there is a central hole 65 in the leaden or other soft metal disc B
which is countersunk as shewn to somewhere about the same taper as the screwed
end e of the polishing mop spindle E so as to readily screw thereon. The leaden
disc B is recessed at 66 on its outer face so as to lighten the same and is made
with a flange or beading 67 round the periphery and another flange or beading 68
round the central hole 65 and is also made with a thickened bead or boss b⁹ round
each of the nail holes 61 62 63 64 so as to strengthen the nail holes and prevent the
nails from cutting the leaden or other metal washer. By making the leaden or
other soft metal washer to the shape as above described it is strong and com-
paratively light.
When the mop A is screwed on to the spindle E the latter being of harder
metal than the leaden or other metal disc B forms the necessary thread in the
hole 65 of the disc B and the latter is stout enough to prevent the drag on the mop
enlarging the hole and the mop from working too far up the spindle. Moreover
when the mop A is unscrewed from the spindle E and again screwed thereon it

page_text: will come into its original position relatively to the spindle and thus run true
thereon.
In the modification of this Invention we provide one of the leaden or other soft
metal washers B on both faces of the polishing mop A instead of only on one face
of the same.
If desired an ordinary leather washer such as D may be used between the leaden
washer B and the face of the polishing mop A. but in practice we do not find that
this is necessary as with the arrangement shewn by our drawings namely the one
leaden washer B on the side of the mop which screws on to the spindle and a
leather washer D on the other side of the same with wire nails driven through
the holes in the leaden washer and through the mop and through the leather
washer and clenched over gives very good practical results.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
1. On that face of a polishing mop which the polishing spindle enters, the
employment of the central countersunk leaden or other soft metal washer such as B,
fixed to said mop by nails driven therethrough and through said metal washer
and through a leather or other washer on the other face of said mop, for the pur-
pose of engaging with the screw threaded polishing spindle and preventing the
mop from working too far up the said spindle, all substantially as hereinbefore
described and illustrated by the accompanying drawings.
2. On the faces of a polishing mop the employment of central counter-sunk
leaden or other soft metal washers such as B, fixed to said mop by nails driven
therethrough and through said metal washers, for the purpose of engaging with
the screw threaded polishing spindle and preventing the mop from working too
far up the said spindle, all substantially as herein before described with reference
to the accompanying drawing.
3. The leaden or other soft metal washers B constructed substantially as herein-
before described and illustrated by the accompanying drawing for fixing to polish-
ing mops as and for the purpose set forth.
