Improvements in Buffing or Scouring Machines employed in the
Manufacture of Boots and Shoes.
I, WILLIAM ROBERT MUDD trading as W. R. Mudd & Co. of Newarke Street,
Leicester, Boot and Shoe Engineer, do hereby declare the nature of this
invention to be as follows:-
--
This invention relates to buffing and scouring machines employed in the
manufacture of boots and shoes and is designed mainly as an improvement upon
the invention for which Letters Patent No. 18523 of 1892 were granted to me and
to Alfred Pochin.
It is found in actual practise that the india-rubber ring, (described in the said
Patent) which carries the emery cloth or other abrading material, when revolving
in contact with a boot or shoe to scour it, becomes heated to such an extent as to
burn the leather and render the latter incapable of being properly finished by the
subsequent well-known finishing processes.
According to my invention I propose to use an elastic ring as set forth in the
prior Patent hereinbefore mentioned, but to prevent the over-heating and
consequent bad results accruing therefrom, I use in combination with the said
elastic ring an outer layer or jacket of felt or other similar or equivalent material
which in actual work is intermediate of the elastic ring and the abrasive cover.

Improvements in Buffing or Scouring Machines employed in the
Manufacture of Boots and Shoes.
I, WILLIAM ROBERT MUDD trading as W. R. Mudd & Co. of Newarke
Street, Leicester, Boot and Shoe 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 :-
This invention relates to buffing and scouring machines employed in the
manufacture of boots and shoes and is designed mainly as an improvement upon the
invention for which Letters Patent No. 18523 of 1892 were granted to me and
to Alfred Pochin.
It is found, however, in actual practise that the india-rubber ring, (described in
the said Patent) which carries the emery cloth or other abrading material, when
revolving in contact with a boot or shoe to scour it, becomes heated to such an
extent as to burn the leather and thereby renders the latter incapable of being
properly finished subsequently by the well-known finishing processes.
According to my invention I propose to use an elastic ring as set forth in the
prior Patent herein before mentioned, but to prevent the excessive heat and
consequent bad results accruing therefrom, I use in combination with the said

page_text: elastic ring a layer or jacket of felt or other similar or equivalent material, which
I interpose between the periphery of the said ring and the abrasive cover.
The invention will be fully understood by reference to the drawing accompanying
this Specification, wherein
Figure 1 is a view of a buffing or scouring wheel or device, (the top part being
in section and the bottom part in elevation) constructed in accordance with my
invention.
Figure 2 is a face view taken on the line Z. Z. of Figure 1.
A represents the rubber ring, shown and described in the prior Patent before
mentioned and B is the endless band or strip of emery cloth or equivalent material
forming the abrasive cover.
The rubber ring 'A is clamped between the two plates C. D. carried on the
spindle E and the remaining parts are also constructed in the manner described in
the prior Patent referred to.
As before mentioned, however, I find that when in operation the wheel or device
such as described engenders such excessive heat as to reduce the prospects of
good results from the usual finishing processes.
To remedy this disadvantage 1 place round the rubber ring A a band of felt or
equivalent material P, the connecting joint P¹ of the said band being chamfered, (as
shewn in Figure 2) and the two edges joined by any suitable adhesive liquid or
the edges of the said band P may be joined together in any other suitable
manner.
The strip of emery or equivalent B is then placed round the band P and secured
thereto in the usual manner.
By interposing a band of felt or equivalent non-conducting material P in the
manner described, the heat engendered during the buffing or scouring operation is
considerably less than is found to arise from the use of the device or wheel
described in the prior Patent before mentioned.
Having now particularly described and ascertained the nature of my eaid
invention and in what manner the same is to be performed, I declare that what I
claim is ;-
1. In a buffing or scouring machine the combination with an elastic emery
carrying ring of a band of felt or equivalent material constructed and operating
substantially as and for the purpose described.
2. The improved emery carrying ring for buffing or scouring machines con-
structed substantially in the manner described and shown in the accompanying
drawing.
