Improvements in or relating to Machines for Buffing or Scouring
the Soles and Heels of Boots and Shoes.
1, FRANK HOWARD Pochin, of Fern Bank, Princess Road, Leicester Engineer, '
do hereby declare the nature of this invention to be as follows:-
This invention has reference to machines for abrading, otherwise termed buffing
or scouring the soles and heels of boots and shoes and embodies improvements
specially applicable to the "Naumkeag" type of machine.
In this machine the emery cover by which the buffing or scouring is effected has
loosely inside, a pad of felt or other flexible material and the said cover and pad
are connected to the holder by two parts of the latter gripping the upper part of
the cover between its two adjacent faces.
The main disadvantages in this construction are (1) that the felt pad moves
about during the scouring process thereby having tendency to disengage the
cover, and (2) the difficulty of getting the pad into and out of the emery cover.
According to the present invention the felt or flexible pad is firmly connected to
the holder practically forming an integral part thereof, so that the cover can be
more easily placed thereon and detached therefrom when desired.
A convenient form of construction for the purpose may consist of securing to the
pad a small circular plate or equivalent having a screw threaded spindle projecting
therefrom which may be screwed into the holder. Or the pad may be screwed or,
otherwise firmly fixed to the holder.
The cover which is formed with an upwardly turned edge is gripped between the
two parts of the holder but one part of the said holder is formed with a ridge or
other form of projection which may fit over and press the cover into a similarly
formed recess or depression on the other part of the holder and thereby increase
the grip upon the cover and hold it more firmly in position.
According to another part of this invention a scouring device is constructed
which, when connected to a revolving spindle, will simultaneously scour the waist
and the breast of the heel of a boot or shoe.
This device may consist of a preferably conically shaped block the base and
sides of which may be covered with felt or other, flexible material.
The flexible base and sides are then covered with emery cloth, the sides of the
device serving to scour the heel breast, and the base of the device at the same time
scours the waist of a boot or shoe.
The cover for this purpose may consist of a piece of emery cloth the central'
portion of which is left large enough to cover the base of the block while the
remainder may, by preference, be cut so as to form strips which can be turned up
on to the sides of the block and suitably secured in position thereon.

Improvements in or relating to Machines for Buffing or Scouring
the Soles and Heels of Boots and Shoes.
I, FRANK HOWARD POCHIN, of Fern Bank, Princess Road, Leicester,
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 has reference to machines for abrading otherwise termed scouring
or buffing the soles and heels of boots and shoes and embodies improvements
specially applicable to the "Naumkeag" type of machine.
In this machine as at present constructed the emery cover by which the buffing
or scouring is effected contains loosely inside, a pad of felt or other flexible material
and the said cover and pad are connected to the holder by the two parts of the
latter gripping the upper part of the cover between its two adjacent faces.
The main disadvantages in this construction are (1) that the felt pad being loose
moves about during the scouring process thereby having a tendency to disengage
the cover, and (2) the difficulty of getting the pad in and out of the emery cover.
According to the present invention the felt or flexible pad is firmly connected to
the holder, practically forming an integral part thereof so that the cover can be
more easily placed thereon and detached therefrom when desired.
A convenient form of construction for the purpose may consist of securing to
the pad a small circular plate or equivalent having a screw threaded spindle
projecting therefrom which may be screwed into the holder. Or the pad may be,
screwed or otherwise firmly fixed to the holder.
The cover which is formed with an upwardly turned edge is gripped between the
two parts of the holder but one part of the said holder is formed with a ridge or
other form of projection which may fit over and press the cover into a similarly
formed recess or depression on the other part of the holder and thereby increase
the grip upon the cover and hold it more firmly in position.
According to another part of this invention a scouring device is constructed
which when connected to a revolving spindle will simultaneously scour the waist
and the breast of the heel of a boot or shoe.
This device may consist of a preferably conically shaped block the base and sides
of which may be covered with felt or other flexible material.
The flexible base and sides are then covered with emery cloth the sides of the
device serving to scour the heel breast and the base of the device at the same time
scours the waist of the boot or shoe.
The cover for this purpose may consist of a piece of emery cloth the central
portion of which is lett large enough to cover the base of the block while the
remainder may by preference be cut so as to form strips which can be turned up
on to the sides of the block and suitably secured in position thereon.
In order to enable this invention to be the more clearly understood I have
appended hereunto drawings to which the following further description refers.
Figure 1 is a central vertical section of a complete buffing pad holder (without
abrasive cover thereon) constructed in accordance with this invention.
Figures 2 and 3 are section and plan respectively of the flexible pad detached
from the holder.
Figure 4 is an elevation of the buffing pad holder, minus the flexible pad and
abrasive gripping device.
Figure 5 is a plan of the underside of the abrasive cover gripping device.
Figure 6 is a central vertical section thereof.
Figure 7 is an elevation of a holder illustrating a modification in the manner of
attaching the flexible pad rigidly thereto.
Figure 8 is a central vertical section of a buffing pad holder and emery .cover

page_text: therefor, for simultaneously performing the two processes of scouring the waist of a
boot or shoe and also the breast of the heel thereof.
A. represents the well known form of flexible pad, which in buffing pad holders
of ordinary construction is usually left loose and separate from the holder.

In consequence of the tendency of the said pad to move about when in action
and thereby disengage the cover as hereinbefore mentioned I propose to secure it
rigidly to the base of the holder and as a convenient construction for this purpose
1 place on the upper part of the said pad a preferably circular plate A' provided
with several downwardly projecting points A' which embed in the pad, and a series,
ot holes A round the margin of the said plate, through which preferably wire'
stitches A may pass to secure the pad and plate together.
The pad and plate may however be united together by any other suitable means.
The said plate A' is also furnished with a threaded spindle A which may be
screwed tightly into a threaded opening B' in the holder B, Fig. 4., so as to
connect the pad and holder rigidly together.
A recess B is formed in the underside of the holder B into which the plate A¹
snugly fits.
It should be understood that I do not coufine myself to this particular method
of connecting the pad and holder rigidly together as other means may be employed
for this purpose and modificatious may be made, one of which is illustrated in
Fig. 7, showing screws B2 passing through the pad A into the holder B to unite
the two parts together.
Any suitable construction of abrasive cover inay be used with the hereinbefore
described holder, but I prefer to employ a cover such as is described in the Specifi-
cation of my Patent No. 174 of 1894.
In order to
The upwardly turned edge or radial tongues of the abrasive cover are fastened
in position on the holder by a well known grip cup C and tightening collar C
which is rotated on the threaded spindle B' of the holder so as to force the cup
downwardly with pressure on the abrasive cover as is well understood.
provide against any possible movement or derangement of the abrasive cover when'
fastened in its operative position on the holder I provide one or more projections
of any suitable kind upon the holder and one or more correspondingly shaped
grooves, openings or recesses opposite to and npon the grip cup, or vice-versa, 80'
that the said projections may force a portion of the abrasive cover into the said
grooves, openings or recesses and thus increase the grip or hold thereon.
One illustration of this feature is given in Figures 4 & 5 in which a projecting
rib or bead B³ is formed on the holder B Fig. 4. and a similarly shaped groove
or recess C¹ to receive it is cut into the inner face of the grip cup C as in Fig 6.
A further part of the invention relates to a buffing pad holder and abrasive cover
therefor, which when in action will simultaneously scour the waist of a boot or
shoe and also the breast of the heel thereof.
A device of suitable construction for this purpose may consist of a conically
shaped preferably wooden core D to which a base E of felt or other flexible
material may be connected by means of a plate A' and screwed spindle A* as
already described with reference to Figures 1. 2. and 3.
To the side of the core D there may be attached by cement or other means a
covering of felt or other flexible material E¹.
The said core may have a screwed stalk A* formed integrally therewith or
connected thereto by an extension of the screwed spindle A*.
Both the felt base E and sides E' are covered by an abrasive covering E* and
for such purpose an abrasive cover similar in construction to that shown and
described in my Patent No. 174 of 1894 but with the radiating tongues sufficiently
long to extend up the sides of the felt covered cone, D, may be employed.
The
tongues of the abrasive cover may be gripped in position by a circular flange F of
well known construction, tightened in position by an internally screwed collar F'.
When the said holder is in operation on a buffing machine that portion of the
abrasive covering E' revolving in a horizontal plane and forming the base of the

page_text: holder will scour the waist of a boot or shoe, while that portion of the abrasive
covering E round the side of the said cone will scour the heel breast thereof.
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. In a buffing or scouring machine a buffing pad holder formed in two parts
between which an abrasive cover is held and gripped and a flexible pad rigidly
connected to the said holder as and for the purpose described.
2. In a buffing or scouring machine the combination of an abrasive cover, a
holder and grip cup such as Cor the like for securing the said cover on the said
holder and a flexible pad rigidly connected to the said holder substantially in the
manuer and for the purpose described.
3. In a buffing or scouring machine the combination of a holder, a flexible pad,
a plate and a spindle connected thereto for attaching the said pad to the said
holder, an abrasive cover for the latter and means for fixing the cover in position
thereon substantially as described and illustrated in the accompanying drawings.
4. In a buffing or scouring machine the combination of an abrasive cover, a
holder for same, a device for gripping the said cover on the said holder, one or
more projections on the latter, and one or more correspondingly shaped grooves,
openings or recesses on the gripping device or vice-versa, substantially as and for
the purpose described.
5. In a buffing or scouring machine the combination of a holder, and an abrasive
covering for the latter constructed in such a manner as to simultaneously scour the
waist and also the breast of the heel of a boot or shoe.
6. In a buffing or scouring machine the combination of a cone-shaped holder,
flexible pad for the base and sides thereof and an abrasive covering therefor and
means for securing the said covering on the said holder substantially in the manner
and for the purpose described.
7. The improvements in buffing or scouring machines consisting of the parts
constructed, arranged and operating substantially in the manner and for the
purpose described.
