Draughtsman, and HENRY ADDISON, Mechanic of the same address, do hereby
declare the nature of this invention to be as follows:-
This invention has reference to machinery used in the buffing or abrading of
the soles and heels of boots and shoes and has for its object an improved means
of fastening the abrasive covering upon the holder and an improved construction of
holder.
The shape and construction of the holder will vary somewhat according to
whether the abrading device is to operate upon the sole and heel of a boot or shoe
or the waist and the breast of a heel thereof.
The essential features in an abrasive covering holder constructed according to
this invention for any of the purposes mentioned are a suitably shaped slot or
opening therein through which two ends of the abrasive covering may be passed
and means for tightening, gripping or otherwise securely fastening the ends of the
said abrasive cover against movement.
According to one form of the invention applicable for abrading the breasts of
heels, a cone or approximately cone shaped holder may be employed having a slot
or opening therein communicating with an opening in the interior of the holder in
which may be located means for tightening or securing the ends of the abrasive
cover.
A convenient means may consist of a block, pin or other suitable device
preferably of the same shape as the internal opening so that when pushed in the
latter it would bear against the ends of the cover and wedge them against the sides
of the opening and thus secure the cover in position.
In some cases the holder may consist of a conical shaped shell and a similarly
shaped solid block to fit therein and grip the ends of the cover passed through an
opening in the shell,
When desired a flexible pad having a screwed spindle attached thereto or other
means may be connected to the base of the holder or shell or to the gripping
device therein, so that when an abrasive cover is put over the said pad and gripped.
or held between it and the base of the holder, the complete device thus formed
may be suitable for buffing or abrading the soles and heels and the waist and the
breast of the heel of a boot or shoc.
Various modifications in the details as regards construction of the holder and
means for fastening the abrasive cover thereon may be made within the main lines
of the invention.

page_text: performed to be particularly described and ascertained in and by the following
statement:-
This invention has reference to machinery for buffing or abrading the soles and
heels of boots and shoes and is designed with the object of providing improved
means for securing the abrasive cover or material, which is generally emery-cloth
or sand-paper, upon the holder.
The essential features in an abrasive covering holder according to this invention
are a suitably shaped slot or opening therein through which the ends of the
abrasive covering may be passed, and devices or means to be used therewith for
gripping, tightening, or otherwise securely fastening or locking the ends of the said
abrasive cover against movement during the operation of buffing the soles and
heels of boots and shoes.
The invention will be fully understood from the following further description
having reference to the accompanying drawings which illustrate two forms of
holders with the abrasive cover secured thereon in accordance with this invention.
Figures 1 and 2 are elevation and plan respectively of one form of holder
showing the parts in position for receiving the abrasive cover the latter being
omitted therefrom for clearness sake.
Figure 3 is a section and Figure 4 an underside plan of a similar holder showing
the abrasive cover fastered in position thereon.
Figure 5 is an elevation of a key to be used for locking the abrasive cover in
position on the holder or removing it therefrom.
Figure 6 is a face view and Figure 7 a central vertical section of a buffing
wheel or roller constructed in accordance with this invention and Figure 8 is an
elevation of a key to be used therewith.
Referring to Figures 1 to 4, A represents a spindle which is fixed to the hollow
rotating shaft of a buffing machine in the well known manner.
The said spindle A is reduced in diameter at one end A' and screw-threaded to
pass through the upper end of the holder B and also into the upper end of the
conical abrasive cover fastening or locking device C located within the said holder
and whose axis is coincident therewith.
D represents the usual coating of felt or similar flexible material and E the
abrasive covering.
The upper part of the holder is formed with a projecting flange or shoulder B₁
which prevents the abrasive cover or felt layer working towards the apex of the
holder and becoming accidentally displaced or removed therefrom while in operation.
For the purpose of fixing the abrasive cover on the holder according to this
invention the conical part B of holder which is cast integrably with B is provided
⚫ with an opening therein through which the ends of the said cover may be passed,
means being employed to lock or secure the said ends, within or against the internal
face of the holder.
A convenient opening for the purpose mentioned consists of a slot B³ extending
from top to bottom of the holder B. A similar slot is formed in the felt coating
and also in the conical-locking device C by which the cover E is secured in position
as hereinafter described. As the height of the conico-locking device is not so great
as the holder B* the slot C' in the said locking device extends a short distance
into the upper part C₁ thereof as most clearly shown in Figures 2 and 4.
The locking device is rotatable on the end of the screwed spindle A¹ to lock or
clamp the ends of the abrasive cover between the side of the said locking device
and the inner surface of the holder B' as hereinafter described.
To move the said locking device in the manner and for the purpose named it is
provided in its upper end with preferably two openings Cinto which the prongs F¹
of a key such as F, Fig. 5, may fit, the said key being furnished with a landle F
by which to turn it.
The movement of the said locking device is limited within the extent of a
slot G formed therein and within which is located the end of a fixed pin or
screw G whose head is buried in a countersunk hole in the holder.

page_text: The peripheral edge of the conical locking device is chamfered at the part
adjacent to the slot so as to leave a space C Fig. 2. between it and the holder
within which the ends of the abrasive cover may be located.
In order to fix the abrasive cover in position on the holder, the locking device C
must first be moved into the position indicated in Figure 2 so that the slot C' therein
is opposite to the slot B³ in the holder thereby forming a clear passage to the
interior of the locking device.
The abrasive cover is then placed round the conical part B of the holder with its
edge close under the shoulders B' which are formed integrally with B' and the ends
of the cover are then passed through the slots B'C'.
The operator now takes the key shown in Figure 5 aud inserts the two prongs thereof
into the openings C'in the locking device and by giving the said key a partial
rotary movement to the right the said locking device is moved into the position
shown in Figure 4 whereupon the ends of the abrasive cover become locked or
clamped between the adjacent faces of the holder and the locking device as shown.
To remove the cover the above operation is reversed.
Referring to the Figures 6 and 7 the same idea is carried out on a buffing roll
or wheel.
H represents the buffing roll the boss H' of which is passed over a shaft and
fixed in position thereon by set screws passing through transverse openings therein
in the usual manner.
On the periphery of the wheel is the usual felt coating over which is placed the
abrasive cover K the ends of which are passed through a slot or opening H2 in the
periphery of the roll and into a similar slot or opening L' formed in the locking
device as shown.
The locking device as here shown consists of two segmental plates L directly
opposite to each other and provided with flanges L2 which are in frictional contact
with the internal face or rim of the buffing wheel H.
These two plates are connected by a boss L³ which also fits over the rotating
shaft of a buffing machine as is well understood.
The said boss is also provided with transverse openings L' therein to receive the
prong or tooth M¹ of a key M such as is shown in Figure 8 and by which to partially
rotate the segmental plates L to cause them to lock the ends of the abrasive cover H
in a similar manner to that already described in reference to Figures 1 to 4, the
movement of the said locking plate being restricted by a screw L' fixed in the
buffing wheel and passing into a slot L' in the said locking device.
The locking device is chamfered at the part adjacent to the slot H2 so as to leave
a space H in which the ends of the abrasive cover may be received in a similar
manner to that described with reference to Figures 1 to 4.
The invention is not limited to the locking devices herein before described and
shown in the accompanying drawings, as it is obvious that within the skill of the
mechanic numerous devices for locking the ends of the abrasive cover to, against
or within the holder may be readily constructed.
It will also be readily understood that the conico-locking device need not
necessarily be slotted or provided with an opening similar to that in the holder, as
after the ends of the abrasive cover have been passed through the opening in the
holder, the operator can, by pressing the said ends against the internal surface of
the latter and inserting the conico-locking device within the holder by a screwing
motion, firmly clamp the said ends against the latter.
The keys shown in Figures 5 and 8 while suitable for the purpose described are
only two out of many forms of keys that could be devised to tighten or release the
locking device in the manner described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the sume is to be performed we declare that what
we claim is :-
1. In a buffing machine the combination of a holder, an abrasive cover therefor,

page_text: a slot or opening in the said holder through which the ends of the said cover are
