PROVISIONAL SPECIFICATION.
Improvements in or relating to Buffing or Scouring Machines used
in the Manufacture of Boots and Shoes.
I, 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 machinery used in the buffing or scouring of the
soles and heels of boots and shoes and is specially applicable to that type of
machine in which the emery or scouring pad is carried on a holder fixed on the end
of a horizontal or vertical revolving spindle.
The said holder is usually constructed in two parts, viz.-the pad or lower
part having a removable circular-faced emery cover, held in position thereon
by the upper part, which is tightened thereover so as to grip the said cover in
position.
Each time the emery cover is to be removed and a new one put in its stead, the
two portions of the holder have to be taken apart and placed together again.
The present invention is designed mainly with a view to admit of the emery
cover being more easily and readily put on and taken off the holder, and
consists of,
(a) Improved means for fastening the said emery cover in position on the
holder:
(b) An improved construction of emery cover: and,
(c) An improved construction of holder which may be (optionally) used
therewith.
Instead of fixing the emery cover in position by gripping it between the two
parts of the holder before mentioned, I provide that the cover and the holder
may each be so constructed, or the said holder provided with means, to permit of
the said cover being easily and readily fixed or attached thereto and detached
therefrom.
For this purpose the said cover may be adapted to engage or to be engaged by
clasps, clips, hooks, pegs, studs, or an annular embracing wire or ring or equivalent
and means for tightening it on the said cover: or the latter may be secured to the
holder by lacing or similar means.
The cover may consist of a suitably shaped, but preferably a circular, piece of
emery cloth having radial extensions or elongations to engage or be engaged by the
means before mentioned.
The holder may be constructed of a single or entire piece with a felt or other
flexible material pad rigidly secured to the base thereof.

Improvements in or relating to Buffing or Scouring Machines used
in the Manufacture of Boots and Shoes.
1, FRANK HOWARD POCHIN of Fern Bank, Princess Road, Leicester
Engineer, do hereby declare the nature of this invention and in what manne
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention has reference to machinery for buffing or scouring the soles and
heels of boots and shoes and relates particularly to the type of machine in which a
disc or cover of abrasive material, such as emery cloth, is connected to a suitable
holder and is rotated rapidly in a plane which intersects or is at right angles to the
axis of rotation thereof.
The invention has chiefly for its object the provision of an improved construction
of abrasive disc or cover and an improved construction of holder which may be
optionally used therewith, and means for fixing the said abrasive cover upon
the said holder all of which are hereinafter fully described and will be
understood from the following description in reference to the accompanying
drawings wherein,
Figure 1 is a central vertical section and Figure 2 a plan of a holder, an
abrasive cover and means for fastening the said cover on the said holder all
constructed in accordance with this invention.
Figure 2 is a detail view of one of the clasps or clips for fastening the covers on
the holder.
Figures 3, 4 and 5 are elevations of holders and abrasive covers thereon
illustrating different means for attaching the cover to the holder.
Figures 6, 7 and 8 illustrate two devices hereinafter described for securing the
abrasive covers on the holder.
Figure 9 is a plan view of an abrasive cover laid out flat and constructed in
accordance with this invention.
Figures 10 and 11 are elevations of abrasive covers with the radial extensions or
tongues turned up at an angle to the acting face of the cover.
Figure 12 is an elevation of a well known form of buffing pad holder but having
my improved abrasive cover connected thereto.
A represents the holder which is widened at the base and has a plate A' screwed
to the underside thereof for the reception of a series of clips or clasps B such as
shown detached in Figure 2^.
The plate A has projecting portions A upon which the clasps B are located
and the said projecting portions are perforated so that the pointed ends of the
clasps B may pass through the same and be clinched against the underside
thereof.
A series of grooves or recesses A³ is made in the block A to allow free movement
to the clasps when the latter are being opened for the purposes of placing the
cover in position on the holder or removing it therefrom.
The clasp B is of the well known form used largely for glove fasteners and
consists as shown in Figure 24 of a base plate 1 two pointed ends 2 (which as
already mentioned pass through openings in the projecting portions A² of the
plate A and are clinched thereunder) a raised central portion 3 which acts as a
spring to control the movement of the lever or arm 4 which is movably pivotted
between the two vertical members 5.
The holder A may have a central downward projection A* Figure 1 which fits
into a similarly shaped recess in a felt or flexible pad C and when desired the latter
may also be connected to the plate A' by stitches (not shown in the drawings)
passing through holes A therein.
Referring to Figure 9 a suitable construction of abrasive cover is there shown

page_text: which is specially adapted for use with the holder and the clasps herein described
although it may be equally well used with holders of the ordinary and well known
construction as shown in Figure 12.
This cover has a circular central portion D forming the acting or scouring face
thereof and from which extensions, elongations, or tongues radiate.
These radial tongues, as they may be termed, may be of varying shapes such
as E. F. G. with various shaped openings or spaces between as E F G¹.
It is not proposed as will be well understood, to employ all of these various
shapes of tongues in one abrasive cover, but for the sake of uniformity one shape
only of such tongues will be used in actual practice with the same cover.
These radial tongues may be fewer or more in number than shown in the
drawings accompanying this Specification, and for fixing the abrasive cover on the
holder the said tongues are turned up at an angle to the acting face D thereof as
in Figures 10. 11 & 12. and when desired are perforated so as to be engaged by the
means illustrated in Figures 1 to 5.
Or the said tongues may be gripped between the two parts of the well known
buffing pad holder shown in Figure 12, the construction of which is so well known
as not to need describing here.
In Figure 1 the perforations in the tongues of the abrasive cover pass over the
lever 4 and are held in position thereby, but in Figures 3. 4. 5. alternative means
of fastening the said cover on the holder are illustrated.
As indicated in Figure 3, headed studs H are screwed into the side of the
holder A and the abrasive cover is held in position by a lace H' passing through
the perforations in the tongues, and over the said studs as shown.
In Figure 4 the shanks of a series of hooks J are secured to the underside of the
base of the holder A so that the hooks project sufficiently far therefrom to admit
of engaging the perforations in the tongues of the abrasive cover while in Figure 5
the same means of fastening are employed but the shanks of the hooks J in this
instance are secured to the outside of the holders.
In a further modification I may make a continuous groove in or round the side
of the holder so that the tongues of the abrasive covers may be laid over the said
groove and be gripped or forced therein by an annular wire or ring, a convenient
construction of which is shown in Figure 6. viz. formed in two parts K. K' suitably
jointed or hinged together at K2 and formed with an overlapping tongue K³ and a
pin K to pass through the same and through the end of the other half of the ring
to fasten the two parts of the latter tightly together over the tongues as before
described. Other forms of annular wires and means for fastening the same
together may be used.
In another modification a circular plate L may be secured to the holder A. by
any suitable means in such a position that the tongues of the abrasive cover would
overlap the same and a similarly shaped plate L' placed over the said tongues and
tightened by screws L³ being forced home through openings L' in the said plate
and also if desired into the holder.
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 machine fastening abrasive covers upon the holders for same by
the several means and in the manner substantially as described and illustrated in
the accompanying drawings.
2. In a buffing machine the use of an abrasive cover having a scries of radial
extensions, elongations or tongues adapted to be turned up at an angle to the acting
face of the said cover as and for the purpose set forth.
3. In a buffing machine the combination of a holder such as A plate such as A'
flexible pad such as C and abrasive covering and means for fixing the latter on the
said holder substantially in the manner and for the purpose described and illustrated
in the accompanying drawings.

page_text: 4. In a buffing machine the combination of a holder an abrasive cover therefor
having a series of radial tongues and a similar series of spaces between the said
tongues, the latter adapted to be turned up at an angle to the acting face of the said
cover and to be attached to the holder substantially as described.
5. The improvements in buffing machines consisting of the parts constructed,
arranged and operating substantially in the manner and for the purpose described
and illustrated in the accompanying drawings.
