COMPLETE SPECIFICATION.
Improvements in or Applicable to Machines for the Manufacture of
Inlaid Floor Cloth and like Fabrics.
We, RUSSELL SCOTT, of the Corticine Works, Ponders End in the County of
Middlesex, Manufacturer, and WILLIAM JOHN BEARD, of 11, Tynemouth Road,
Tottenham, in the County of Middlesex, Engineer, 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 machines for the manufacture of that
kind of floor cloth known as linoleum and of like fabrics on which there is a design
or pattern the colors of which are inlaid or continuous through the substance of
the material and especially to that class of such machines in which a series of die
or pattern plates having openings corresponding to different parts of the pattern is
employed as for instance in the machine described in the Specification of our
application No. 17081 of 1891.
The said invention has for its object to provide apparatus or means for
mechanically introducing and removing such die or pattern plates in their proper
order or succession into and from such a machine.
In carrying out our invention we provide a framework carrying a series of guides
so arranged that the die or pattern plates can be moved thereon through a circuit,
that is to say, the said guides are so arranged that each die or pattern plate can
be first pushed beneath the punches which operate in conjunction with the die or
pattern plates from one side of the machine then pushed from beneath the punches
through the other side of the machine, then moved transversely onto a guide upon
which it is pushed back to the side of the machine at which it is introduced and
then transversely in an opposite direction to the transverse motion previously
referred to into line with the said guides beneath the punches and so on.
In practice all the pattern plates of the series used in the production of a pattern
are at different parts of the guides and during the time that the said die or pattern
plates are passing around the circuit the pieces of punched material lying thereon
are removed and fresh pieces of material of the required colors are applied.
We prefer to introduce the die or pattern plates beneath the plungers by means
of a drum having reverse screw threads or spiral grooves engaging with a pusher
in such a manner that when the pusher has been pushed forward by the thread in
one direction it will be returned to its original position by the thread or groove in
the reverse direction and we arrange the pattern plate carrying the piece of
material which is to be next punched to push out the pattern plate carrying the
material which has been previously operated upon. The other transverse and
longitudinal movements of the plates are effected by means of sprocket chains
carrying bars designed to engage with the plates at suitable intervals.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings as applied to the machine described in
the Specification of our former application No. 17081 of 1891.
In the said drawings
Figure 1 is a plan view of our apparatus in conjunction with a machine of the
kind described in our said former Specification, and
Figures 2 to 17 are views of details hereinafter described.
Similar letters of reference indicate corresponding parts in the several figures,
and the parts of the machine described in the said former Specification and shewn
in the accompanying drawings are indicated by the same letters as in the said
Specification.
A is a metal frame having guides B B from which the pattern plates g, g are

page_text: The
introduced beneath the plungers, the guides CC on to which the said pattern
plates run as they are pushed from beneath the plungers; the transverse guides DD
upon which the plates pushed out of the machine are moved transversely; the
longitudinal guides E, E upon which the plates are moved back again to that side
of the machine at which they are introduced and the transverse guides F, F upon
which the plates are moved from the longitudinal guides E, E back to the
guides B, B from which they are again introduced into the machine.
guides B, B consist of two plates and of a guide flange B', the said guides being
shewn most clearly in Figure 2 which is a section on the line 22 Figure 1. The
guides C, C are composed of plates of the shape shewn in Figures 3 and 4 which
are sections on the lines 3, 3 and 4, 4 respectively of Figure 1. The transverse
guides D, D are arranged as shewn in Figure 5 which is a section on the line 55
Figure 1. The longitudinal guides E, E are similar to the guides C, C, as shewn
at the left hand end of Figure 3 and in Figures 6 and 7 which are respectively
sections on the lines 6, 6 and 7, 7 Figure 1. The guides F F and their arrangement
will be understood by reference to Figure 8 which is a section on the line 8, 8
Figure 1. Figures 2 to 8 are drawn to a larger scale than Figure 1.
G is the drum having the spiral grooves which drum is mounted in suitable
bearings in the brackets of the frame A immediately beneath the guides B, B, the
said drum being rotated by means of a gear wheel G' on the shaft described in
the Specification hereinbefore referred to engaging with a pinion G' having formed
integral with it a wheel G³ engaging with a pinion G₁ upon the axle of the drum.
This spirally grooved drum and its connected mechanism is shewn drawn to an
enlarged scale in Figures 9 to 12, Figure 9 being a plan of the said screw and the
connected parts, Figure 10 an elevation, Figure 11 a left hand end view and
Figure 12 a right hand end view.
G is the right hand groove of the drum, G is the left hand or reversed groove
thereof and H is the pusher or slide which is operated by the reversed grooves of
the said drum. This pusher which is shewn in longitudinal section in Figure 13
and in end elevation in Figure 14 comprises a sliding plate H' having pivotted to
it and projecting beneath its underside a traveller H which is adapted to work in
the groove of the drum G. The said sliding plate has also on its underside a
pivotted lever H³, one end of which carries a bar H adapted to be projected above
the surface of the slide H, in order to engage with the pattern plate to be pushed
forward by means of a cam surface H' on the surface of the drum G, which cam
surface at a certain part of the rotation of the said drum is designed to act against
the lower end of the said bar H. The other end of the lever H carries a tappet H
against which another cam surface H7 on the drum G is designed to act in order to
operate the said lever H to withdraw the bar H beneath the surface of the
guides B, B during the time that the said slide H is being moved backwards.
It will be noticed that the ends of the groove in the drum G have no inclination,
and the object of thus constructing the ends of the groove is that no longitudinal
movement shall be imparted to the slide H during the time that either of the cam
surfaces H or H' is acting upon the lever H³.
The operation of this part of the feeding apparatus is as follows:-Assume the
slide H and the projecting bar H to be in the position shewn in Figures 9 and 10
(which is the position they occupy immediately after a pattern plate has been
pushed into the machine beneath the punches) and the traveller H in the straight
portion of the groove at one end of the drum G. As now the drum rotates no
longitudinal movement will for a short period be imparted to the slide H but
during this time the cam surface H7 will act upon the tappet He to move the
lever H³ to withdraw the bar H below the surface of the slide. Immediately this
is accomplished the right hand groove G³ moves the slide to the right hand end of
the drum, having reference to Figures 9 and 10. Immediately that the traveller H
enters the straight portion of the groove at the said right hand end, the cam H
acts upon the lower end of the bar H to project the same above the surface of the
guide for pushing another pattern plate forward.

page_text: As hereinbefore stated the pushing of one pattern plate into the machine causes
the pushing out of another plate onto the guides C, C. The conveyance of the
pattern plate so pushed out across the guides D, D is effected by means of two
sprocket chains I, I running on sprocket wheels I', I' and having between them
bars I³, 12.
One of these bars I* and portions of the chains II to which it is connected is
represented in Figures 15 and 16 which are respectively a side elevation and a plan.
It will be noticed by reference to these figures that the bars I are composed of
angle iron, except the end portions which are attached to angle pieces upon the
chains.
The bars 1, 12 are arranged on the chains at such distances apart as to give
the necessary interval between the transference of the plates from the guides C, C
to the guides E, E.
The movement of the plates along the guides E, E is effected by means of a
sprocket chain J carrying projecting pieces J¹ as shewn most clearly in Figure 17
which is a plan of a portion of such a sprocket chain with one angle piece J¹
thereon.
The transference of the plates from the guides E, E over the guides F, F to the
guides B, B is effected by means of sprocket chains arranged in a similar manner
to the chains I, I.
In order to have sufficient length of chain for carrying the bars I³, I' at the
necessary distance apart, we provide on the under side of the frame A arms K, K
carrying adjusting pulleys K', K' as shewn in Figures 1, 2 and 3.
Motion is imparted to the chains as follows:-that is to say, the shaft L
carrying two of the sprocket wheels supporting the chains I, I of the guides F, F
is driven from the shaft of the reversed screw G by means of a pinion L' engaging
with an intermediate wheel L' which drives a wheel L' upon the shaft L. The
motion of this shaft L is communicated through the said chains I, I of the
guides F, F to a shaft M having gearing at one end which serves to operate
the shaft M carrying one of the sprocket wheels for driving the chain J of the
longitudinal guides E, E. This chain J transmits the motion imparted to it to
gearing at N which imparts motion to a shaft N¹ carrying the sprocket wheels I'
upon which the chains I, I of the guides D, D run, the gearing at N being so
proportioned that the chains of the guides D, D will run at the same speed as the
chains of the guides F, F.
The operation of this apparatus as a whole will be understood from the following
description:
:-
'
Assume one of the pattern plates. g to have been just pushed into position
beneath the punches and to have pushed out another plate indicated by the cross
dotted lines g' on to the guides C, C. Assume also that the other six plates of
the series occupy the positions indicated by the cross dotted lines at g³¸ Ð², Ìˆ‚Ì', 9³, Ì².
During the time that the punches are operating upon the material upon the plate g,
the chains of the guides D, D will by means of the bars I transfer the plates g', g³, 9³
so far laterally that the plate g will be brought on to the guides E, E and at the
same time the chains I, I of the guides F, F will transfer the_plates g*, 9°, g' so
far laterally that the plate g' will be brought onto the guides B, B.
Immediately after the punches are raised, and whilst the press-head remains in
its uppermost position during half a revolution of the shaft as described in the
said former Specification the left hand thread G, of the spirally grooved drum G
operates the slide H to push the plate g' beneath the plungers and to push the
plate g onto the guides C, C; at the same time the chain J is operated to move
the plate 9 longitudinally on the guides E, E, the said plate at the same time
pushing forward the plate o into such a position that it can be taken by one of the
cross bars I of the chains I, I of the guides F, F.
The punches now descend to press out the material upon the plate g', and at the
same time the chains of the guides D, D, operate to transfer the plate onto the
guides E, E and the chains I, I of the guides F, F operate to transfer the plate 9*

page_text: onto the guides B, B and the plate onto the guides F, F. The same operation
is repeated as each plate passes under the punches.
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 combination with a machine of the kind hereinbefore referred to and
having a series of dies or punches operating in conjunction with a series of die or
pattern plates, of mechanism for introducing and removing the said die or pattern
plates successively into and from the said machine, substantially as described.
2. The improved apparatus for introducing and removing die or pattern plates,
consisting of the parts constructed and combined substantially in the manner
herein before described and illustrated in the accompanying drawings and operating
as, and for the purposes, set forth.
