COMPLETE SPECIFICATION.
Improvements in Buffing-pads and Tools for Buffing or Treating the
Bottoms of Boot and Shoe Soles and other like Articles.
I, SAMUEL HEY of 56 Low Street, Keighley in the County of York, Patent
Agent, do hereby declare the nature of this invention, as communicated to me
from abroad by The Globe Buffer Company of Boston, Massachusetts, United
States of America, 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-pads for buffing or treating the bottoms of boot
and shoe soles and other like articles, in which a disk of cloth or paper, coated on
one side with emery or other abrasive material, is placed upon a yielding support
and is rotated rapidly, the axis of rotation being substantially at right angles to
the plane of the abrasive surface of the pad.
The invention has for its object to provide an improved form of pad, adapted to
be quickly and securely applied to the holder or carrier which supports it, and to be
as readily removed when worn out. The invention also has for its object to provide
an improved form of holder or carrier, adapted to co-operate with the improved
form of pad, and to these ends the invention consists in the improvements which I
will now proceed to describe and claim.
Of the accompanying drawings, forming part of this Specification;
Fig. 1 represents a plan view of a buffing-pad constructed in accordance with my
invention the pad being in a flat condition.
Fig. 2 represents a perspective view of the pad, showing its margin turned up,
preparatory to being applied to a holder or carrier.
Fig. 3 represents a perspective view of a holder or carrier and a pad secured
thereto, all in accordance with my invention.
Fig. 4 represents a section on line 4-4 of Figure 3.
Fig. 5 represents a sectional view, showing an appliance used in placing the pad
upon its holder or carrier.
Fig. 6 represents a modification of the clamping device.
The same letters of reference indicate the same parts in all the figures.
In carrying out my invention, I make a pad by cutting out a flat sheet or blank a
from a piece of cloth, paper or other suitable flexible material, coated on one side
with suitable abrasive material, such as emery. The blank a is made in sub-
stantially circular form, and in its margin are formed numerous slots or recesses a¹,
which subdivide the marginal portion of the pad into tongues or ears a². I prefer
to make the slots in the form shown in Fig. 1, each slot being preferably rounded
at its inner end and gradually contracted in width from its inner, to its outer end,
I find that, by making the slots in this form, that is, with comparatively wide inner
ends, the pad may be moulded or turned upwardly on a line somewhat inside the
inner ends of the slots, as shown in Fig. 2, without forming any angles or pro-
tuberances on the line of turning, and that the contraction of the slots at their
outer ends gives the tongues sufficient width to enable them to be securely held by
the clamping devices hereinafter described. By thus moulding or preparing the
pad, I provide the same with a flange, which includes the tongues and is formed to
surround the seat on the pad-holder hereinafter described, so that the pad can be
quickly and easily applied to the holder.
After the slots and tongues are formed, the marginal portion of the pad, including
said tongues, is bent upwardly by a suitable moulding process, substantially at right
angles with the main or operative portion of the pad, as shown in Fig. 2, thus

page_text: forming the flange above mentioned, and the pad in this condition is applied to a
holder or carrier b. Said holder or carrier is preferably made of elastic or yielding
material, as shown in British Letters Patent No. 9123 of 1893, and is preferably
provided with an air-chamber, communicating through an air duct c with a source
of air-supply, as shown in said Patent. The holder has a circular margin, above
which is a seat 61, which, as here shown, is bevelled or inclined, and is formed to
support the tongues a² when said tongues are bent inwardly against said seat, as
shown in Figs. 3 and 4.
The tongues a² of the pad may be confined upon the holder by means of an
elastic band d, formed to contract upon the tongues and press them closely against
the seat, as shown in Figures 3 and 4. To aid the band d in holding the tongues
in place, I prefer to provide the holder b with a shoulder or projection 62, which
constitutes a wall formed to support the tongues against the inward pressure
exerted upon them by the contraction of the band.
•
In practice, I prefer to apply the pad to the holder in the following manner;
the tongues a² being turned upwardly, as shown in Figure 2, I place the pad in a
sheet-metal box or holder e, having a narrow marginal portion or rim el, of sufficient
width to support the band d, and of such diameter as to hold the band in a distended
position. I then place the pad upon the holder, pressing the main or operative
portion of the pad against the holder thus causing the tongues to project above the
margin of the holder. I then press the band e upwardly off from the margin of the
box, thus allowing it to contract upon the holder and find its place, as indicated in
Figs. 3 and 4. It will be seen that the pad is thus quickly and securely applied to
the holder, and may be as readily removed by pulling off the ring d.
I do not limit myself to the employment of a chambered holder or carrier b, as
the described improvements may be used upon a holder which is not provided with
an air-chamber.
The holder is here shown as clamped between two metal disks or collars
comprising a rigid head, which is, suitably secured to a shaft o² in which the air-
duct c is formed. The holder is also shown as provided with a bottom b³, which
forms one side of the air-chamber communicating with the duct c, and extends
across the inner side of the operative side of the pad. Said bottom is preferably
provided with one or more orifices, which permit air to pass through the
bottom & into contact with the pad, thus preventing the latter from being over-
heated by friction.
The bottom may be made integral with the holder, or in a separate piece
attached thereto and both the holder and the bottom may be of any suitable
flexible material, such as rubber, canvas, leather, etc.
The seat b', made integral with the bottom and of elastic or yielding material,
constitutes a frictional support, which prevents slipping of the tongues of the
holder, and is more effective in this respect than would be the case if the seat were
of rigid material.
The tongues of the pad may be secured to the holder by means of any other
suitable device or clamp, and I do not limit myself to the employment of an elastic
ring or band. If desired a metal clamp may be employed, composed of two
parts ss, hinged together at sa like a bracelet, and having suitable locking-devices
at their swinging ends, the whole being adapted to be applied and removed like a
bracelet.
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. As an article of manufacture, a buffing-pad, marginally slotted or recessed to
form a series of tongues, and moulded to form a flange which includes said tongues,
said flange standing substantially at right angles with the acting face of the pad,
whereby the pad is adapted to be readily applied to a holder having a seat for said
tongues, as set forth.

page_text: 2. As an article of manufacture, a buffing-pad, having in its margin tapered slots
or recesses forming a series of tapered tongues which are widened at their outer
portions, the pad being moulded to form a flange which includes said tongues and
stands substantially at right angles with the acting face of the pad, said flange
being bent from the body of the pad along a line somewhat within the inner ends
of the slots, so that the margin of the acting face of the pad is continuous or
unbroken, as set forth.
3. A buffing-pad holder, having an elastic pad-supporting face, and an elastic
tapering or frusto-conical seat surrounding said face and arranged at an acute angle
therewith, said seat having a shoulder at its upper portion; combined with a pad
marginally slotted or recessed to form a series of tongues, and moulded to form a
flange which includes said tongues, the flange being formed to surround said seat;
and a clamp adapted to press the upper portions of said tongues against the seat
and shoulder; as set forth.
Deted this 20th day of March 1894.
