Improved Pad for Scouring the Bottoms of Boots and Shoes, for use
on the Naumkeag Scouring Machine or any similar Machine.
I, RICHARD Cheatle ChallONER of No. 41 All Saints Road Leicester in
the County of Leicester Boot and Shoe Manufacturers Foreman, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an improved pad for scouring the bottoms of boots
and shoes, for use on the Naumkeag scouring machine, or any similar machine.
In the pads now made the seam round the edge does not allow of the top of the
underside of the heel to be scoured and consequently a buffing knife has to be
brought into requisition.
I obviate this by making the pad in the following manner.
I take a piece of emery cloth or paper and shape it upon a suitable circular
bevelled mould, of wood or other material then gather together or pleat the edges
over being careful not to leave any creases on the edge. It is then pressed when
it assumes the required form or shape to fit upon the scouring block or head of
the machine to be secured thereon in the usual way. Space is left in the upper or
enclosed portion of the pad so that a disc of felt or the like may be inserted before
securing it to the block.

.COMPLETE SPECIFICATION.
Improved Pad for Scouring the Bottoms of Boots and Shoes, for use
on the Naumkeag Scouring Machine or any similar Machine.
I, RICHARD CHEATLE CHALLONER, of 122 Curzon Street, (late of 41 All
Saints Road) Leicester, 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 is designed with the object of producing an improved construc-
tion of emery pad or cover for use with a Naumkeag or similarly constructed
machine employed to scour the bottoms of boots and shoes.
The invention will be understood from the following further description in
reference to the accompanying drawings in which
Figure 1 is a perspective view and Figure 2 a transverse section of an emery
cover of the ordinary type used in connection with the scouring machine before
mentioned.
Figures 3 and 4 are plan and section respectively of my improved emery cover,
and Figure 5 is a perspective view of the holder with my improved emery cover
thereon.
The ordinary type of emery cover shown in Figures 1 and 2, consists of a
disc A of emery cloth stitched to the turned under edge B₁ of a disc B of canvas
cloth provided with slits B2 to permit of being placed over the usual holder C and
gripped thereon in the usual well known manner.
The seam round the edge of this cover does not permit of the upper part of the
breast of the heel near the waist of the boot or shoe being scoured, in consequence
of which the operator uses a buffing knife to finish the process.
By the use of my improved emery cover constructed in one piece as hereinafter

page_text: described the breast of the heel of a boot or shoe may be completely scoured and
the use of the buffing knife entirely dispensed with, thus completing in one
operation what has heretofore required two.
To construct the improved emery cover I use a preferably circular or disc
shaped piece of emery cloth D and concentrically thereover I may place a cone
shaped block or equivalent, of a smaller diameter, say three-fifths or thereabouts..
The marginal edge D¹ of the emery cloth is then turned upwardly round the
base of the cone and on to the side of the latter and pleated or over-lapped in the
manner shown most clearly in Figure 3.
To obtain the best results from the one piece emery cover it is desirable that
the pleatings do not extend to the edge D2 of the emery cover as the latter should
have a smooth and uniform edge all round free from creases and depressions as
indicated most clearly in Figure 4.
A disc of felt or other flexible material may be placed within the cover before it
is attached to the holder so as to sustain the edge of the cover while in use.
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 I
claim is :-
1. An emery cover, for a boot and shoe scouring machine of the character
described, constructed of a single piece substantially as described.
2. An emery cover, for a boot and shoe scouring machine of the character
described, consisting of a single piece of emery cloth the marginal edge of which
is turned up all round and pleated or overlapped substantially as described.
3. An emery cover, for a boot and shoe scouring machine of the character
described, consisting of a single piece of emery cloth the marginal edge of which
is turned up all round and pleated or overlapped so as to leave a smooth and
uniform edge thereto substantially as described.
4. The improved construction of emery cover for a boot and shoe scouring of the
character described, substantially as described and illustrated in Figures 3, 4, & 5
of the accompanying drawings.
