PROVISIONAL SPECIFICATION.
Improvements in and connected with Shaving Brushes.
I, ARTHUR COCHRANE HAMILTON, of Spencer House, Ryde, Isle of Wight,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and connected with shaving brushes.
In carrying out my invention where a solid soap is employed I make the handle
of the brush hollow so as to adapt it to receive a stick of shaving soap. The end
of the said hollow haudle is open and is tapered slightly so as to prevent the
stick of soap from leaving the same and is provided with a screw or other cap or
cover.
A spiral or other spring is arranged at the bottom of the hollow handle the said
spring being provided with a piston adapted to press against the inner end of the
stick of soap so as to tend to force it out through the tapered end of the hollow
handle.
By this arrangement it will be obvious that by removing the cap or cover and
subjecting the stick of soap to the action of hot water the outer end of the stick of
soap will be caused to project from the handle by the spring sufficiently to allow
of the face being soaped.
Where a soft soap or shaving composition is employed the piston in the hollow
handle is adapted to be operated by a screw instead of a spring so as to force the
soap as required through an opening in the top of the handle and into and through
a flexible tube into the bristles of the brush.
I propose to form the handles of my brushes with a recessed shoulder to receive
the drainage from the bristles which is thereby prevented from running down the
handle as hitherto.
I, ARTHUR COCHRANE HAMILTON, of Spencer House, Ryde, Isle of Wight,
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 :-
This invention relates to improvements in and connected with shaving brushes.
In carrying out my invention where a solid soap is employed I make the handle
of the brush hollow so as to adapt it to receive a stick of shaving soap. The end
of the said hollow handle is open and is tapered slightly so as to prevent the
stick of soap from leaving the same and is provided with a screw or other cap or
cover.

page_text: A spiral or other spring is arranged at the bottom of the hollow handle the said
spring being provided with a piston adapted to press against the inner end of the
stick of soap so as to tend to force it out through the tapered end of the hollow
handle.
By this arrangement it will be obvious that by removing the cap or cover and
subjecting the stick of soap to the action of hot water the outer end of the stick of
soap will be caused to project from the handle by the spring sufficiently to allow
of the face being soaped.
A series of holes is formed round the contracted end of the handle to cause the
stick of soap to cool more quickly and in cases where a soft variety of shaving
stick is employed I fix a pin or wire across the open lower end of the handle to
prevent the soap issuing too freely from the same.
Where a soft soap or shaving composition is employed the piston in the hollow
handle is adapted to be operated by a screw instead of a spring so as to force the
soap, as required, through an opening in the top of the handle and into and through
a flexible tube into the bristles of the brush.
In practice I advantageously form the handles of my brushes with a recessed
shoulder to receive the drainage from the bristles which is thereby prevented from
running down the handle as hitherto.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is an elevation of a shaving brush made according to my invention and
adapted to hold a solid stick of soap:
Figure 2 is a vertical section of the same:
Figure 3 is an end view of the handle with the cap or cover removed and shewing
the cross pin or wire:
Figure 4 is a vertical section of a shaving brush made according to my invention
and adapted to contain a soft soap or shaving composition:
Figure 5 is a section on the line 4-4 Figure 4.
Similar letters of reference indicate the same, or corresponding; parts. in the
several figures.
Referring to Figures 1 and 2 a is the brush, b the hollow handle,. the said hollow
handle being made open at its end and having the edges tapered slightly inwards
as shewn at c, c Figure 2. c', c are the holes formed around the said inturned
edge and d is the stick of shaving soap in the hollow handle b, the said soap being
held in the same by the inturned edge c of the handle.
e is the cap or cover which is fitted on to the open-end of the handle b when the
soap is not required for use is the spiral spring arranged in the hollow handle b
behind the stick of soap and-g is the piston which fits, the, interior of the hollow
handle b. and 'presses upon the end of the stick of soap d so that the pressure of the
spring upon the piston 9 tends to force the soap out through the tapered end of
the hollow handle, the said stick being retained in the hollow handle 6 by the
inturned edge c of the same as hereinbefore described.
.
With this arrangement it will be obvious that by removing the cap or cover e
and subjecting the stick of soap b to the action of hot water the outer eud of the
said stick.of soap. will. be-forced out-from-the handle-6 by the spring f sufficiently
to allow of the face being soaped.
k; Figure 3,. is the, pin or wire fixed across the open end of the handle 6 for
preventing a soft. variety.of soap stick from being forced out too quickly from the
handle, whenisoftened.
In Figures 4 and 5 the hollow handle b is adapted to receive a soft soap or
shaving composition instead of a stick of shaving, soap d.
h is the screw, which operates the piston g the said screw being connected at its
lower end to the cape on the handle 6 so that when the said cap. is rotated the
piston is moved up and down in the handle. i is the tube passing from the top of
the hollow handle into the bristles or hairs a of the brush, the extremity of the
said tube being formed of india-rubber so as to prevent injury to the skin. j is the

page_text: funnel which guides the soap or composition into the tube i when the piston is
operated. The piston g is prevented from rotating with the screw h by a ridge or
projection 6' on the inside of the hollow handle, which projection enters a corre-
sponding groove in the piston as shewn clearly in Figure 5.
With this arrangement it will be obvious that when the cap e on the end of the
hollow handle b is turned in one direction on the said handle 6 the screw is rotated
and causes the movable piston g to force the soft soap or shaving composition
through the tube i and into the bristles a of the brush.
The neck of my brush to which the bristles a are secured is provided with a
recess for the reception of the drainage from the said bristles and is detachably
connected to the said handle so as to allow a fresh stick of soap to be inserted
when necessary or to permit soft soap or shaving composition to be introduced.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. A shaving brush having a hollow handle adapted to receive a stick of soap
and a piston pressed against the inner end of the stick of soap by a spring, the said
stick of soap being retained in the handle by the inturned edge of the open end of
the handle, substantially as, and for the purpose, described.
2. A shaving brush having a hollow handle adapted to contain a soft soap or a
shaving composition and having a piston designed to be operated by a screw for
forcing the soap or composition from the hollow handle into a tube passing from
the said handle into the end of the bristles of the brush, substantially as, and for
the purpose, bereinbefore described.
3. The manufacture and use of the improved shaving brushes hereinbefore
described and illustrated respectively in Figures 1, 2 and 3 and Figures 4 and 5 of
the accompanying drawing.
