An Improved Manufacture of Razor-strop.
I, JOHN HENRY KEELING of Ashford Lodge, Charlwood Road, Putney in the
County of Surrey, Gentleman, do hereby declare the nature of this invention to be
as follows:-
In the manufacture of razoi strops, it has been found desirable, in place of a flat
surface on which to strop, to employ a convex surface (that is, convex in cross
section), the traveise of the 1azoi over the stop (in the act of sharpening it) being
in the direction both of the length of the strop and the length of the razor blade.
Moreover, it has been found necessary to make this convex surface elastic, so that
its point d'appui may yield to the pressure of the razor, and thus modify the action
of the sharpening of polishing surfaces. To obtain this elasticity and roundness,
the leather surface has been cushioned by cotton wool. but as this has a tendency to
condense under pressure, the elasticity of the strop surface is soon lost, and with it
the desirable convex shape first imparted to the surface of the strop.
To remove these disadvantages is the object of the present invention
I now
propose to use, as a filling or cushion between the surface of the stop and its
backing, or stick, a permanently elastic stuffing, which may consist of a longitudinal
arched strip of vulcanised india-rubber or other compound, or it may be a moulded
strip of spongy rubber. This permanently elastic stuffing will ensure the main-
tenance of the desned shape of the surface of the stop, its tendency being to yield
to the pressure of the razor travelling rapidly over it, and to return to its normal
shape immediately the pressure is removed

An Improved manufacture of Razo
I JOHN HENRY KEELING of Ashford Lodge Charlwood Road Putney in the
County of Surrey Gentleman 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
-
In the manufacture of razol strops it has been found desuable in place of a flat
surface on which to stop, to employ a convex surface, (that is convex in cross
section), the traverse of the razor over the strop (in the act of sharpening it) being
in the direction both of the length of the strop and the length of the razor blade.
Moreover it has been found necessary to make this convex surface elastic so that
its point d'appui may yield to the pressure of the razor and thus modify the action
of the sharpening or polishing surfaces. To obtain this elasticity and roundness,
the leather surface has been cushioned by cotton wool, saw dust and similar
materials, but as this has a tendency to condense under pressure, the elasticity of
the strop surface is soon lost and with at the desuable convex shape hist imparted
to the sin face of the strop.

To remove these disadvantages 18 the object of the present invention.
propose to use as a filling or cushion between the surface of the strop and its
backing or stick, a permanently elastic stuffing, which may consist of a longitudinal
arched strip of vulcanized india rubber or other compound, or it may be a moulded
strip of spongy rubber. This permanently elastic stuffing will ensure the main-
tenance of the desired shape of the surface of the strop, its tendency being to yield
to the pressure of the razor travelling rapidly over it, and to return to its normal
shape immediately the pressure is removed.
In the accompanying drawing, I have shown at Fig. 1 m perspective view a
razor strop as produced according to my invention.
Fig. 2 is a cross section of the same.
Figs. 3 and 4 are cross sections of a strop showing slight modificatious in the
construction of the strop.
A is the backing of the stop or stick, B is the surface of the strop, which will
be of leather as usual, and C is the permanently elastic stuffing
In Fig. 2 this stuffing C consists of a strip of vulcanized udia rubber or other
compound laving a width shghtly greater than that of the stick and which 19
retained in position by drawing the surface leather tightly round the strop and
securing it to the edge of the stick by some adhesive material or in any othei well
known and convenient manner. The stup of rubber is thus caused to mich, leaving
an air space between it and the stick which gives an increase of elasticity to the
surface of the strop. Or the arcbcd strip may be moulded with bevelled edges and
attached by some suitable adhesive material to the stick, the leather being secured
to or round it in any convenient manner.
In Fig 3 the stuffing C is shown as consisting of a solid moulded pad or stup of
vulcanized rubber or other material, while in Fig. 4 a solid moulded pad or strip of
spongy rubber is shown.
The modes of securing these pads or strips with the leather round them may
vary. Thus I may tuin the leather in under the pad and secure both to the stick
by an adhesive material. I may also combine an arched strip and a solid pad in
the same strop if desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
clann is
1. A razor strop having a rounded elastic surface or surfaces produced in the
manne herein shown and described.
2. In a razor stop having a rounded elastic surface or surfaces the use of an
arched strip of rubber or a sold moulded strip or pad of vulcanized rubber or other
compound for the filling or stuffing as set forth.
