PROVISIONAL SPECIFICATION.
Improvements in or applicable to Razor Strops.
I, JOHN HARVEY DICKSON, of. Townsend, St. Albans, in the County of
Hertford, Contractors' Agent, do hereby declare the nature of this invention to be
as follows:-
My invention relates to razor strops and has for its object to provide means
whereby the surface upon which the sharpening is effected shall possess more
elasticity than strops as at present constructed whereby a much keener edge than
heretofore can be put upon a razor.
According to my invention I arrange in conjunction with or attached to the
leather or other material upon which the sharpening is effected a spring or
springs.
When my invention is applied to an ordinary strap-strop which is adapted at one
end to be attached to a fixed point and at the other end held in the hand I may
insert a piece of india-rubber into the strap at one end or the eye or ring for
connection to a fixed point or forming the handle of the strop may be connected
with a metal or other spring or formed of indiarubber or the like. A simple
form of attachment for use in connection with an ordinary strap-strop consists
simply of an india-rubber ring and a hook attached thereto or of a metal ring and
hook having a spring arranged between them.
When the strap is attached to a permanent foundation it may be connected
thereto at either end or at both ends by an elastic or metal spring and in some
cases I form the said foundation in such a manner that it can be folded up.

COMPLETE SPECIFICATION.
Improvements in or applicable to Razor Strops.
I, JOHN HARVEY DICKSON, of Townsend, St. Albans, in the County of
Hertford, Contractors' Agent, 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 :-
My invention relates to razor strops and has for its object to provide means
whereby the surface upon which the sharpening is effected shall possess more
elasticity than strops as at present constructed, whereby a much keener edge than
heretofore can be put upon a razor.
According to my invention I arrange in conjunction with or attach to the leather
or other material upon which the sharpening is effected a spring or springs.
When my invention is applied to an ordinary strap-strop which is adapted at
one end to be attached to a fixed point and at the other end held in the hand, I may
insert a piece of india-rubber into the strap at one end; or the eye or ring for
connection to a fixed point or forming the handle of the strop may be connected
with a metal or other spring, or formed of india-rubber or the like. A simple
form of attachment for use in connection with an ordinary strap-strop consists
simply of an india-rubber ring and a hook attached thereto; or of a metal ring
and hook having a spring arranged between them.

page_text: When the strap is attached to a permanent foundation it may be connected
thereto at either end or at both ends by an elastic or metal spring and in some
cases I form the said foundation in such a manner that it can be folded up.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figures 1 to 4 shew the arrangement of a spring or other yielding device formed
as a part of the strop :
Figures 5 to 10 illustrate various arrangements of a spring-attachment designerl
to be used in connection with an ordinary strap-strop; and,
Figures 11 to 16 illustrate different methods of arranging the flexible
connections of strops having permanent foundations.
In the arrangement shewn in Figures 1 and 2 the strop a has a piece of india-
rubber inserted into it at one end, so that when the said strop is connected by the
eye c with a hook and the link d grasped at the other end, it will yield slightly to
the pressure of the razor upon it.
Figure 3 shews a spiral-spring' b in connection with the ring c of the strop, the
said spring being arranged between one end of the loop e upon the end of the
strop and a cross-bar/secured to the shank of the ring c.
In Figure 4 an india-rubber ring g is connected to the loop e, which ring may
either be engaged with the hook to which the strop is connected at one end; or it
may be held in the hand, the strop being connected to the hook at the other end.
Instead of providing the strop itself with a flexible portion, I may employ a
separate device which can be attached to the strop at one end and either held in
the hand or attached to a fixed hook. One form of such a device is shewn in plan
and elevation in Figures 5 and 6 and consists simply of a spiral-spring having a
hook at one end for attachment to the strop and an eye or ring at the other end.
Figures and 8 shew another arrangement in which an india-rubber ring is
attached to a hook.
In the modification shewn in Figure 9 the flexible connection is constructed
upon the principle embodied in Figure 3, the loop e in this case having attached to
it a hook to which the strop is connected.
In the arrangement shewn in Figure 10, a flexible piece is arranged between
the hook and the ring e in the manner shewn in Figures 1 and 2.
In Figures 11 and 12 which shew in plan and side elevation a strop attached to
a permanent foundation, I have represented the strop provided with a yielding
device at each end, such device being constructed upon the principle described by
reference to Figure 3, except that the ring c is dispensed with, the loop e being
connected to the foundation h.
As shewn in Figure 13 the strop, instead of having a yielding device of the kind
herein before described, is connected at its two ends to springs i, i attached to the
foundation and yielding in the desired manner under the pressure of the razor.
The strop shewn in Figures 14, 15 and 16 is provided with yielding connections
similar in construction to that shewn in Figures 1 and 2. This strop is also
adapted to be folded up, as shewn in Figure 16, and for this purpose it is
provided at the centre with a hinge and one end of the strop has attached to
it hooks, k, k adapted to be connected to and disconnected from the link con-
nected to the foundation h.
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. The combination with a strop of a spring or other flexible device adapted
to yield under the pressure of a razor upon the strop,, substantially as and for
the purpose described.
2. A yielding connector adapted to be used in combination with a strop, sub-
stantially as described.

page_text: 3. The improvements in strops and in yielding connectors for use in connec-
tion therewith, substantially as hereinbefore described and illustrated in the
accompanying drawings.
