Improvements in Polishing Appliances, Applicable for Setting
the Edges of Boot Soles and the like,
I, EDWARD BALLY, of Schoenen werd, Switzerland, Shoe manufacturer, do hereby
declare the nature of this invention to be as follows:-
-
A Polishing appliance according to this invention comprises a turned polishing
"bit" which can be readily. made, and be easily changed. This bit may be formed
of several pieces. It is held, clamped or fastened to a handle or holder of suitable
construction.
In order to explain the nature of this invention, there are appended by way of
example two sheets of illustrative drawings. In these,
Figs. 1. to 4. illustrate a bit the working portion of which consists of a single
piece A. constituting the top of the appliance.
Figs. 5. to 8. show a polishing appliance and edge-setting tool the bits A¹ & A² of
which constitute the top angles or corners of the tool.
Figs. 1. 2. and 3, and Figs. 5, 6 & 7, are respectively the front elevation, side
elevation and plan, of the two polishing appliances; Figs. 4 & 8 are perspective
views of the same.
The polishing tool (Figs. 1. to 4.) comprises a main portion in two pieces. One
piece (the frame B) carries the pin or tang D for the handle. The other (the
plate B¹) is fixed to the frame B, by means of a screw b as shewn.
The bit A consists of a segment of a turned ring; by this method of construction
both its working top surface and the dove-tail surface e c¹ may be produced in a lathe
with exactness and without great trouble. The dove tail cel fits between corresponding
parts of the pieces B B¹.
с
•
The plate 13 presses the dove tail e c¹ firmly in its place, while it fits exactly upon
the frame B.
- By this invention the tool is prevented from becoming cooled too quickly by a
current of air passing through the space that would otherwise be left between B & B¹.
The working top surfaces a² a' a² a³ a¹ a³ aº, side surfaces a°, and hase with the
dove-tail c c have all one single centre or axis, resulting from the method of
production in the lathe.
The upper (cylindrical) surface of the piece B B' corresponds exactly with the
lower surface (containing the dove-tailed slot) of the bit A.
The working parts can be produced very exactly and easily; and in place of the
setting operation which is requisite with the tool hitherto employed it is merely
nocessary to clamp in a new bit A when required.
The polishing tool (figs. 5. to 8.) which may also serve as an edge-setting tool,
comprises two bits A¹ A formned of segments of turned rings.
The plates B1 and B2 are screwed on to the frame B in such a manner as to effect
the clamping of the dove-tails e¹ and c² of the bits A1 and A2 whilst at the same time
the plate B and B2 fit exactly upon the frame B which carries the peg or tang D
for the handle.

Improvements in Polishing Appliances, Applicable for Setting
the Edges of Boot Soles and the like.
I, EDWARD BALLY, of Schoenenwerd, Switzerland, Shoe Manufacturer, 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 :-
A polishing appliance or burnisher according to this invention comprises a polishing
"bit" which is detachable and shaped on the turning lathe. This method of manu-
facture assures a perfect adjustment and an easy exchange of the piece. The tool
may also comprise several pieces or bits. It is held, clamped or fastened to a handle
or holder of suitable construction.
In order to explain the nature of this invention, there are appended by way of
example three sheets of illustrative drawings. In these,
Figs. 1 to 4 illustrate a bit the working portion of which consists of a single piece A
constituting the top of the appliance.
Figs. 5 to 12 show polishing appliances, burnishers or edge-setting tools, the bits A'
and A2 of which constitute the top angles or corners of the tool.
Figs. 1, 2 and 3, Figs. 5, 6 and 7 and Figs. 9, 10 and 11 are respectively front
elevations, side elevations and plans, of such polishing appliances; Figs. 4, 8
and. 12 are perspective views.
The polishing tool (Figs. 1 to 4) comprises a main portion in two pieces. One
piece (the frame B) carries the pin or tang D for the handle. The other (the
plate B¹) is fixed to the frame B by means of a screw bas shewn. The bit A consists
of a segment of a turned ring; by this method of construction both its working top
surface and the dove-tail surface c c c may be produced in a lathe with exactness
and without great tro-ble. The dove tail c c c fits between corresponding parts of
the pieces B B'. The plate B' presses the dove-tail c c c firmly in its place, while it
fits exactly upon the frame B. To prevent the tool from becoming cooled too quickly
by a current of air passing through the space between B and B₁ the adjacent faces
of B and B are fitted to each other.
The working top surfaces a a² a³ a a' a, side surfaces a° and base with the
dove-tails ccc have all one single centre or axis, resulting from the method of
production in the lathe.
The upper (cylindrical) surface of the piece B B₁ corresponds exactly with the
lower surface (containing the dove-tailed slot) of the bit A.
The working parts can be produced and inserted very exactly and easily; when
the operating faces are worn out it is merely necessary to clamp in a new bit A
when required.
The polishing tool (Figs. 5 to 8) which may also serve as an edge-setting tool and
for similar purposes comprises two bits A1 A2 formed of segments of turned rings, the
axes of these pieces being the same as the respective axes of the turned faces of the
dove-tails c¹ c².
The plates B and B are screwed on to the frame B in such a manner as to effect
the clamping of the dove-tails c¹ and 2 of the bits A' and A' whilst at the same time
the plates B1 and B2 fit exactly upon the frame which carries the peg or tang D
for the handle.
.
The Figs. 9 to 12 shew the same tool with two bits A' and A' but modified as
regards the axis about which they are turned, this axis being the same for the
two bits.
Having now particularly described and ascertained the nature of the said inven
tion and in what manner the same is to be performed, I declare that what ]
claim is :-
1. In a polishing instrument or burnisher, a detachable piece of which the operating
surfaces such as a 2 side surfaces ench
and hottam hearing or fitting faces

page_text: are curves having a common axis which is also the axis of the respective bearing or
fitting surfaces, such as c c c¹ (or co c¹ c³ or cº c² c¹) of the frame B (or B B¹ or B B²)
substantially as shown and described.
2. In a polishing instrument or burnisher, the combination of the frame B and the
plate B' or plates B' and B' with the polishing detachable piece A or pieces A³ and A'
each of the said detachable pieces having its operating surfaces, side surfaces and
bearing or fitting faces constructed as curves having a common axis.
