PROVISIONAL SPECIFICATION.
A Method of and Apparatus for Simultaneously Forming and
Spreading Lather, Paste, or other similar Substance upon a
Suitable Surface.
I, WILLIAM BRUCE GORDON HOGG, of Bedford Park, Chiswick, in the County
of Middlesex, Doctor of Medicine, do hereby declare the nature of this invention
to be as follows :-
My invention relates to a method of and apparatus for simultaneously forming
and spreading lather, paste or similar substance on a suitable surface the said
invention offering certain advantages and being applicable to certain useful
purposes.
The nature of my invention, in so far as it relates to the method, consists in
abrading a solid body by rubbing the same upon a surface and at the same time
mixing the abraded matter with a solvent, or liquid or viscous medium, so as to
form a paste or lather or similar substance, whilst simultaneously with the said
abrading & mixing action the said substance is spread over the said surface
by means of a device hereinafter for the purposes of this Specification termed
a spreader, & which may consist of a brush, pad, roller or other similar or
equivalent contrivance.
The nature of my invention, in so far as it relates to the apparatus, consists of
an arrangement of parts combining with the spreader & the body to be abraded a
holder or retainer which may not only serve to hold or retain the body to be
abraded but also serve as a handle for the spreader & in some cases as a container
for the medium hereinbefore mentioned.
The principle of action of my invention lies in the simultaneous abrasin of
the said body, the formation of the lather or paste or the like, and the spreading
of the same on the surface. Rapidity of operation and saving of time are thus
obtained.
My invention is specially applicable to such purposes as the following: Covering
the face with a lather for shaving; coating a surface with paint or varnish; sealing
the joints of pipes, cases and the like; covering sheets of tissue or fabric with an
adhesive layer for the purpose of affixing the same to other surfaces; covering
fabrics or tissues with waterproof or air-proof layers; coating the backs of books
before applying the covers in binding; applying laundry requisites, detergents and
the like to fabrics; manufacturing medical or surgical plasters; applying glazes to
earthenware before firing; pickling or cleaning metallic surfaces before galvanising
or electrodepositing other metals thereon; cleaning tarnished surfaces; polishing
wood, marble & other surfaces; and, generally, renewing surfaces already existing
and or superposing new surfaces upon other surfaces.

A Method of and Apparatus for Simultaneously: Forming and
Spreading Lather, Paste, or other similar Substance upon a
Suitable Surface.
I, WILLIAM BRUCE GORDON HOGG, of Bedford Park, Chiswick, in the County
of Middlesex, Doctor of Medicine, 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 a method of and apparatus for simultaneously forming
and spreading lather, paste or similar substance on a suitable surface the said
invention offering certain advantages and being applicable to certain useful
purposes.
The nature of my invention, in so far as it relates to the method, consists in
abrading a solid body by rubbing the same upon a surface and at the same time
mixing the abraded matter with a solvent, or liquid or viscous medium, so as to
form a paste or lather or similar substance, whilst simultaneously with the said
abrading and mixing action the said substance is spread over the said surface by
means of a device hereinafter for the purposes of this Specification termed a
spreader and which may consist of a brush, pad, roller or other similar or equivalent
contrivance.
The nature of my invention, in so far as it relates to the apparatus, consists of
an arrangement of parts combining with the spreader and the body to be abraded a
holder or retainer which may not only serve to hold or retain the body to be
abraded but also serve as a handle for the spreader and in some cases as a container
for the medium hereinbefore mentioned.
The principle of action of my invention lies in the simultaneous abrasion of the
said body, the formation of the lather or paste or the like, and the spreading
of the same on the surface. Rapidity of operation and saving of time are thus
obtained.
My invention is specially applicable to such purposes as the following: Covering
the face with a lather for shaving; coating a surface with paint or varnish; sealing
the joints of pipes, cases and the like; covering sheets of tissue or fabric with an
adhesive layer for the purpose of fixing the same to other surfaces; covering fabrics
or tissues with water-proof or air-proof layers; coating the backs of books before
applying the covers in binding; applying laundry requisites, detergents and the
like to fabrics; manufacturing medical or surgical plasters; applying glazes to
earthenware before firing; pickling or cleaning metallic surfaces before galvanising
or electrodepositing other metals thereon; cleaning tarnished surfaces; polishing
wood, marble or other surfaces; and, generally, renewing surfaces already existing
and or superposing new surfaces upon other surfaces.
Having thus described the nature and objects of my invention, and so defined its
scope, I shall now, in order that my invention may be better understood, proceed
to show in what manner it is to be or may be performed or carried into effect. For
such reason I have annexed hereunto sheets of drawings illustrative of my invention
and have marked thereon figures and letters of reference which correspond with
those employed in the following description. In these figures similar letters
indicate similar or equivalent parts. I desire it to be understood that the apparatus
hereinafter described is to be regarded merely as typical and illustrative. I do not
in any way limit myself to the devices shown as these may vary within wide limits
without departing from the spirit of my invention.
Figure 1 is an elevation, Figure 2 a longitudinal section and Figure 3 a transverse
section (on the line 1, 1, of Figure 2) of a form of my invention which is very

page_text: suitable for working up a paste or lather upon a surface: and it in fact constitutes
a very convenient form of shaving brush. In describing it I shall refer to it as if
it were a shaving brush. A represents the substance to be abraded, in this case a
stick of shaving soap, which is gripped in the threaded socket B. This socket
moves vertically within the tube C, a groove in the said socket fitting over the
guide c which prevents the said socket from rotating as it is moved to and fro.
D is a union-piece screwing on to the tube C so as to connect the same with the
handle-piece E to which it is attached in such manner as to rotate freely without
altering its position relatively to the said handle. F is a left-handed screw
attached to the socket-piece B and threading through the union-piece D in such
manner that when D is rotated the said screw works upwards and pushes up the
socket-piece B and consequently the shaving stick A also. Upon the upper end of
the tube C is the brush washer G shown in section in Figure 2 and in plan in
Figure 4. The said washer is threaded on either side of the central flange so that
its lower thread may engage a female thread on the upper part of the tube C and
its upper
thread engage the cap-piece H. The brush washer G is perforated with
a circle of holes so as to permit of the attachment of the bristles J in a well known
manner. The bristles therefore form a brush concentric with the shaving stick A.
H is a cap fitting over the bristles for purposes of protection and screwing on to
the brush washer as herein before described.
and
Figure 5 is a plan of the shaving brush just described with the cap H thereon
Figure 6 a plan with the cap removed.
r
To use this form of shaving device the handle E is turned until the end of A.
will bear upon the skin without undue deflection of the bristles J. The bristles are
then dipped in water and the device applied to the skin in the usual manner of a
shaving brush whereupon the upper end of the shaving stick is abraded and the
action of the wet bristles works the abraded matter into a lather spreading it over
the skin. As the stick A becomes worn down all that is needed is to rotate the
handle when the socket-piece is elevated and a greater length of shaving stick
exposed ready for use as described.
Figure 7 is a device which differs from that shown in Figure 2 simply in the fact
that for the bristles J a pad J' is substituted to spread the abraded matter over the
surface.
Figure 8 is a plan of the device shown in Figure 7.
The device shown in Figures 7 and 8 is very suitable for polishing surfaces
when A is a substance_containing more or less gritty matter such as soaps for
polishing metal or wood or lacquer, or when it consists of pumice stone or the
like.
Figure 9 represents another form of my apparatus which differs from the forms
already described in the mechanical means of feeding forward the substance to be
abraded. In this case the socket-piece B has a projecting part 6 to which is
attached a pin b', the said pin protruding through a longitudinal slot c¹ and being
attached to a slide ring c². This contrivance for feeding forward the material to be
abraded is similar to that employed in a well known form of pencil case for feeding
forward the lead. care notches extending from the slot c¹ into the wall of
the tube C for the purpose of sustaining the pin 6 when the latter is pressed into
the said notches by a side movement of the ring c². When the pin b¹ rests in these
notches the strain upon the material to be abraded is taken up by the tube C and
the substance to be abraded is thereby retained in position instead of being pressed
back as would otherwise be the case. K is an end piece screwing into the tube C
and keeping the same closed at its lower extremity.
A brush or pad or other form of spreader may be adapted to this device according
to the purpose for which it is to be applied.
Figure 10 is a transverse section of the device last mentioned taken on the
line 2 to 2.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The method of simultaneously forming lather, paste or other similar substance
upon a surface substantially as set forth.
2. The apparatus for simultaneously forming lather, paste or other similar
substance upon a surface substantially as set forth.
3. The combination of a holder or retainer a solid body to be abraded and a
concentric spreader substantially as and for the purpose set forth.
4. The arrangement and combination of parts constituting the specific device set
