Improvements in the Manufacture of Inlaid Fabrics for Covering
Floors and other Surfaces, and in Apparatus Used for this
Purpose.
We, ARTHUR SIDNEY OETZMANN, 67 to 79 Hampstead Road, London,
Manufacturer and SAMUEL JOHN NARRACOTT, 12 Victoria Parade, Torquay,
do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of "inlaid " linoleum and like fabrics
in any required pattern.
To effect this object we employ a machine having a horizontal sliding frame to
which a step-by-step motion is given. On this frame is secured a plate having
fixed on it at proper respective distances groups of raised bosses, one group for
each colour and the bosses are shaped to correspond with the figures required.
Each group of bosses has working up and down on it a perforated slab or table;
the perforations fit the bosses and allow the table to be raised or lowered to any
required position on the bosses. When the perforated table is raised to a sufficient
height, the perforations form cells which are closed at the bottom by the bosses.
A hopper, properly divided into compartments and filled with granulated linoleum
material in different colours is then drawn across the perforated tables and the cells.
are all charged with the colours required.
The charged cells of one table are then by the step motion brought beneath the
transferring-block. This transferring-block is of suitable thickness and on its
under surface the outline of the entire design is formed of strips of steel about an
inch wide which are made to stand on edge by being firmly driven into saw-cuts or
slits in the block to the depth of about a third of an inch. The result is a number
of cells corresponding to the whole of the figures in the design and all have
suitable ejecting-plates fixed to plungers which pass through and project beyond
the upper surface of the block.
When the transferring-block is pressed down onto one of the perforated tables
the table slides downwards on the bosses causing the granulated material which
was in its perforations to be transferred to and compressed into the corresponding.
cells on the transfer-block.
This operation is repeated with all the perforated tables in succession and they
then pass to be re-filled.
The transferring-block is now brought down onto the backing fabric and by the
plungers the whole design is ejected simultaneously, complete as to all its parts
and colours.
Further consolidation under heat and pressure finishes the process.

Improvements in the Manufacture of Inlaid Fabrics for Covering
Floors and other Surfaces, and in Apparatus Used for this
Purpose.
We, ARTHUR SIDNEY OETZMANN of 67 to 79 Hampstead Road, London,
Manufacturer and SAMUEL JOHN NARRACOTT of 12 Victoria Parade, Torquay,
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 the manufacture of "inlaid " linoleum and like fabrics in
any. required pattern. To effect this object we employ a machine having a
horizontal sliding frame to which a step-by-step motion is given. On this frame
is secured a plate having fixed on.it at proper respective distances groups of raised
bosses, one group for each colour and the bosses are shaped to correspond with the
figures required.
Each group of bosses has working up and down on it a perforated slah or table.
The perforations fit the bosses, and allow the table to be raised or lowered to any
required position on the bosses.
When the perforated table is raised to a sufficient height the perforatious form
cells which are closed at the, bottom by the bosses. A hopper properly divided
into compartments and, filled with granulated linoleum material in different colours
is then drawn across-the perforated tables and-the-cells are all charged with the
.colours required.
The charged cells of one table are then by the step-motion brought beneath the
transferring-block. This transferring-block is of suitable thickness and on its
under surface the outline of the entire design is formed of strips of steel about an
inch wide which are made to stand on edge by being firmly driven into saw-cuts or
slits in the block to the depth of about a third of an inch. The result is a number
of cells corresponding to the whole of the figures in the design and all have suitable
ejecting-plates fixed to plungers which pass through and project beyond the upper
surface of the block.
When the transferring-block is pressed down onto one of the perforated tables
the table slides downwards on the bosses causing the granulated material which
was in its perforations to be transferred to and compressed into the corresponding
cells on the transfer-block. This operation is repeated with all the perforated
tables in succession and they then pass to be re-filled.
The transferring-block is now brought down outo the backing-fabric and by the
plungers the whole design is ejected simultaneously complete as to all its parts
and colours.
Further consolidation under heat and pressure finishes the process. For the
sake of greater couvenience in working we prefer to construct our machine in such
a manner that instead of giving the step-by-step notion to the perforated tables
we fix these tables to the framework of the machine and give the step-motion to
the transferring-block and the rising-and-falling motion to the plates with bosses.
This is the method adopted and shown in the drawings..

page_text: and Fig. 4 the apparatus used for moving the backing-fabric intermittently (not.
shown in Fig. 1).
The action of the machine is as follows:-A. A A2 are hoppers open at the
bottom and containing the granulated material in different colours. These at
suitable periods are drawn across the perforated tables B B B and by this means
the perforations are charged with a supply of granule. C is the transferring-block:
which moves in guides C step-by-step to its proper successive positions over the
tables B B' B. As it arrives over each table the plates with the groups of bosses D-
D1 D2 are in turn raised by the cams E E E on the shaft F and compress the
granule into the respective compartments of the transferring-block. The bosses
then recede to allow the transferring-block to be moved forward. The depth
to which the bosses recede is regulated by the screws D³ on which the
plates D D D rest.
The transfer-block C after receiving its final colour from table B passes over
the fixed table G and on the plate K being depressed the whole completed design.
in slabs of linoleum composition is at once deposited upon the canvas backing G¹
prepared to receive it. M is the roll of canvas backing which is fed onto the-
endless carrying-band M. The endless band M' is studded with pins and the
blanketted roller N presses the canvas backing onto the pins. The further action
of this part of the machine is described in the reference to Fig. 4.
By means of the revolving arms H. H' the transfer-blocks C. are in rotation-
returned to the first position and one block is passing through the machine step-by-
step while the other is being returned overhead.
The block C receives its step-by-step motion from the reciprocating rod J which
is furnished with pawls to engage with the block in a suitable manner.
The transferring-block C is made as follows:-To the main block K (see Fig. 3)
is attached a thinner block K' and on K¹ a complete outline of the design is drawn.
Every portion of the thin block enclosed by an outline is then screwed to block K.
K' is next unscrewed and fret-cut and the separated pieces again screwed to K..
which ensures that only the thickness of the saw-cnt is left between them. Int
the saw-cuts thin strip-steel K is tightly driven on edge and the result is a series
of cells conforming to the required design. Each cell is fitted with an ejecting-
plate K³ to which a plunger K is attached. The plungers pass through the
block K and being fixed to the plate K all the ejecting-plates are actuated
simultaneously.
The apparatus shown in Fig. 4 would in use be attached to table G. It consists
of a drum O which drives an endless band M' furnished with pins for carrying the
canvas backing.
The drum is actuated in the following manner. The lever P (which is
adjustable at the slot P' for controlling the throw) gives a reciprocal motion to the
rods Q&Q. On these rods are pawls Q which engage with the ratchet-wheel O'
keyed to druin O. This combination of movements and parts secures that at the
end of each stroke one of the pawls is brought into a position at right-angles with.
its motive power as shown in the drawing and acts as a stop to prevent back-stretch
of the canvas until the next forwarding motion is taken up by the other pawl..
A slight slop in the levers allows a moments' rest of the endless band and backing
during the net of ejecting the pattern onto it.
The linoleum being complete as to pattern passes to suitable presses to be
finished,
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. For the purpose of manufacturing inlaid linoleum and similar fabrics the-
combination of machinery described and shown in the drawings.
2. In the manufacture of inlaid linoleum the use of a series of perforated tables.
fitted with sliding bosses which close the base of the perforations, means for raising.

page_text: and lowering the bosses and hoppers for charging the perforations or recesses with
granulated composition.
3. In the manufacture of inlaid linoleum the use of a transferring-block in which
the outline of the design is completely formed of thin steel or other suitable
material placed on edge. Means for filling the block with composition in various
colours from recessed tables over which the block passes and means for ejecting
the completed design in all colours simultaneously onto the canvas backing.
4. The construction of the transferring-block substantially as shown in Fig. 3
and described.
5. In the manufacture of linoleum and other fabrics by the machinery aforesaid
the construction and use of the apparatus shown in Fig. 4 consisting of an endless
band studded with pins, drums for carrying the band and the arrangement of
ratchets and pawls which by finishing their stroke at a dead-point prevent back-
pull or stretch of the fabric substantially as described.
