PROVISIONAL SPECIFICATION
Improvements in the Manufacture of Floorcloth and in Apparatus
therefor.
We, HENRY WILLIAM GODFREY, CHARLES FREDERICK LEAKE Engineers
and CHARLES EDWARD LUCAS Linoleum Manufacturer all of Staines in the
County of Middlesex do hereby declare the nature of this invention to be as
follows:-
In the Specification of a former Patent granted to us dated the 23rd day of
March 1888, No. 4482 we described a machine for producing from granulated
linoleum material of different colours a floorcloth in imitation of granite.
We
The object of the present invention is to produce a marbled or marbled granite
appearance. For this purpose we cause strips or threads of linoleum material to
adhere to a granulated surface in the process of manufacture. As in the former
case we cause the backing to pass beneath a hopper which delivers upon it linoleum
fragments, the thickness of the layer of fragments being regulated by a straight
edge at the mouth of the hopper which receives an endway vibratory motion.
then dust or distribute upon the surface of such fragments before they have been
consolidated by the rollers strips or threads of linoleum material; the fabric then
passes to rollers similar to those described in the former Specification and the
manufacture is completed, the strips or threads being incorporated into the surface
giving the appearance of veins.
The strips or threads can be produced in various ways, the method we prefer to
adopt is to pass linoleum material between two rollers one of which is heated and
the other kept cold. The material is thus squeezed into a film which adheres to
the cold roller. After the nip of the rollers there is a pressing or rubbing surface
bearing on the cold roller the result being that the film is rolled or rubbed into
elongated shreds which are flicked off by a revolving brush and distributed over the
granular material already spread on the backing fabric. Or the linoleum com-
position may be rubbed between two flat or conical surfaces and collected to be
afterwards distributed in any suitable manner.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Floorcloth and in Apparatus
therefor.
We, HENRY WILLIAM GODFREY, CHARLES FREDERICK LEAKE Engineers,
and CHARLES EDWARD LUCAS, Linoleum Manufacturer all of Staines in the
County of Middlesex, 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 Specification of a former Patent granted to us dated the 23rd day of
March 1888 No. 4482 we described a machine for producing from granulated
linoleum material of different colours a floorcloth in imitation of granite.
The object of the present invention is to produce a marbled or marbled granite
appearance in floorcloths and similar fabrics used for covering other surfaces. For

page_text: this purpose we cause strips or threads of linoleum material to adhere to a granulated
surface in the process of manufacture. As in the former case we cause the backing
to pass beneath a hopper which delivers upon it linoleum fragments, the thickness
of the layer of fragments being regulated by a straight edge at the mouth of the
hopper which receives an endway vibratory motion.
We then dust or distribute
upon the surface of such fragments before they have been consolidated by the
rollers strips or threads of linoleum material; the fabric then passes to rollers
similar to those described in the former Specification and the manufacture is
completed, the strips or threads being incorporated into the surface giving the
appearance of veins.
The strips or threads can be produced in various ways, the method we prefer to
adopt is to pass linoleum inaterial between two rollers one of which is heated and
the other kept cold. The material is thus squeezed into a film which adheres to
the cold roller. After the nip of the rollers there is a pressing or rubbing surface
bearing on the cold roller the result being that the filin is rolled or rubbed into
elongated shreds which are flicked off by a revolving brush and distributed over the
granular material already spread on the backing fabric. Or the linoleum com-
position may be rubbed between two flat or conical surfaces and collected to be
afterwards distributed in any suitable manner.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a diagram view shewing a vertical section of an apparatus constructed
according to this invention and Figure 2 is a plan of the same.
a is a roll of canvas or other material to form the backing, it is mounted on a
truck a running on wheels a². The backing passes round guide rolls beneath
the mouth of the hopper e and has delivered on to it a layer of linoleum material.
"
The backing then passes under the straight edges d d (which regulate the depth
of the layer of material upon it) to the pressing rolls ee which consolidate the
material and cause it to adhere to the backing. All this is old and well known and
requires no further description. is a counter shaft carrying four pulleys over
which pass the belts 3 and 4. The belt passes over a pulley on the
shaft which has upon it a pinion gearing with a spur wheel upon the axis of
the roll. The other end of the axis of the roll has fixed to it the spur wheel h
gearing with the spur wheel jt upon the axis of the roll j. The belt f* passes over
a pulley upon the axis of the roll & which drives the endless belt. The belt f
drives the brush m and the belt drives the feed roll n¹ at the mouth of the
hopper n. o is an incline to direct the material from the roll n onto the rolls h
and j. リ is a block whose upper edge acts as a scraper for the roll; but does not
quite touch the roll the space between this roll and the block being as shewn
greater on the entrance than the exit side. r is a set screw for adjusting the
block 4.
e
The action of the apparatus is as follows the rolls e and shaft are caused to
revolve being driven by a main shaft and gearing not shown in the drawings. The
revolution of the rolls draws the backing off the roll a under the mouth of the
hopper e where it receives a layer of linoleum material, this layer is made smooth
and of an even thickness by the straight edges d d. The revolution of the shaft/
causes the roll n' to revolve and deliver linoleum material from the hopper n onto
the roll which is heated. This material descends between the rolls and j and is
squeezed into a film which adheres to the cold roll h. This film passes down
between the roll and the blocky and is rubbed or rolled into strips or threads
which are flicked off by the revolving brush u and drop onto the endless running
band and are delivered onto the layer of linoleum material on the backing. The
backing with its layer of linoleum materials and strips or threads passes to the
heated rolls ee which consolidate the whole together.
Figures 3 and 4 are similar views of a modification in which there are two
belts two hoppers n two rolls n' two blocks and two inclines o.
The two

page_text: j
hoppers n preferably contain material of different colors. p is a partition separating
the rolls and each of which acts independently rolling or rubbing the material
between itself and its block 9. In this case the material is not first squeezed into a
film. m is a brush for flicking off any pieces which may adhere to the band l, these
drop into the hopper c and are incorporated in the body of the ground. In other
respects the operation of this machine is the same as that first described and its
parts bear the same letters.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1.The process of manufacturing floorcloth and similar fabrics with a marbled
or marbled granite surface by causing strips or threads of material to adhere to the
material forming the ground.
2. The process of manufacturing floorcloth and similar fabrics with a marbled
or marbled granite surface by rubbing or rolling linoleum or like material between
two surfaces, dusting the strips or threads so formed onto the material forming the
ground and afterwards consolidating the whole together.
3. The process of manufacturing floorcloth and similar fabrics with a marbled or
marbled granite surface by spreading fragments of linoleum or like material evenly
upon a backing of canvas or other fabric, dusting upon such fragments strips or
threads of linoleum or like material and then consolidating the whole together.
4. The process of manufacturing floorcloth and similar fabrics with a marbled
or marbled granite surface by spreading fragments of linoleum or like material
evenly upon a backing of canvas or other fabric dusting upon such fragments strips
or threads formed by rubbing or rolling linoleum or like material between two
surfaces and then consolidating the whole together.
5. Apparatus for producing strips or threads substantially as described and
shewn in the drawings.
