A Machine for Pressing Materials which are in Continuous or Long
Lengths.
1, HENRY MICHAEL STEINTHAL of Scarborough in the County of York, Managing
Director of the Scarborough Patent Tiled Floor Cloth Company, Limited, do hereby
declare the nature of this invention to be as follows:-
My invention consists of a machine for pressing materials which are in continuous
or long lengths, and it is constructed so as to bring strong, direct downward pressure
upon successive sections of the material during intermittences in the onward movement
or travel of the latter. The machine has been specially designed for pressing sheets
or pieces of paint composition used in the manufacture of floor cloths, wall coverings, or
for other like purposes, the said sheets or pieces being arranged in any required order
as to color upon a length of cloth; but it is applicable in other cases where continuous
or long lengths of material have to be pressed.
My machine consists essentially of (1) a rising and falling plunger or presser; (2) a
fixed table or block against which the pressing is effected; (3) mechanism whereby
the material to be pressed is moved forward intermittently between the plunger and
the table, each movement being equal to the width of the pressing face of the plunger;
and (4) a steam heated cylinder over which the material is led before reaching the
plunger; this cylinder will, however, only be required in cases where the material has
to be warmed or softened before.pressure.
Having explained the nature and main features of my machine, I will describe more
in detail how it can be constructed.
an
Above a fixed table or pressing block is arranged a plunger or presser having
up and down movement. This movement can be produced in any convenient manner;
a suitablé arrangement for the purpose consists of excentrics on a rotating shaft,
communicating motion through links to a sort of cross-head, which is connected by
vertical bars to the plunger. At one side of the press is a steam heated cylinder,
over which the material to be pressed, say a roll or length of cloth covered with sheets
or pieces of paint composition, is led from a roller or otherwise. From the steam
heated cylinder the cloth is led between the plunger and the pressing block, and the
end is attached to a travelling band which draws it forward intermittently as about to
be described. Upon a wheel, which may be on the same shaft as the excentric which
actuates the plunger above described, is a crank pin connected by a rod to an arm
mounted loosely on the shaft of a pulley which drives the travelling band; this arm
hus a pawl which takes into a ratchet wheel on the pulley shaft. The result of this
arrangement is that as the crank pin in the revolution of its wheel is approaching the
pulley, it causes the arm above described to push round the ratchet wheel by means
of its pawl; consequently the travelling band, and therefore the length of paint
covered cloth are caused to move a certain distance, that is to say, a distance equal to
the width of the plunger. During this forward movement of the cloth the plunger is
raised from the bed or pressing block. Then as the crank pin in the revolution of its
wheel is receding or moving away from the pulley, the arm and pawl are drawn back,
the pawl riding over the ratchet teeth; therefore there is no movement of the cloth,
and it is during this interval or intermittence of the movement that the plunger comes
down and presses that part of the material which is then below it. This intermittent
action continues until the whole length of the cloth or material has been pressed in
*successive sections. The travelling band should be as long as the roll or length of

A Machine for Pressing Materials which are in Continuous or Long
Lengths.
I, HENRY MICHAEL STEINTHAL of Scarborough in the County of York, Managing
Director of the Scarborough Patent Tiled Floor Cloth Company Limited, 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 consists of a machine for pressing materials which are in continuous
or long lengths, and it is constructed so as to bring strong direct downward pressure
upon successive sections of the material during intermittences in the onward
movement or travel of the latter. The machine has been specially designed for
pressing sheets or pieces of paint composition used in the manufacture of floor cloths,
wall coverings or for other like purposes, the said sheets or pieces being arranged in
any required order as to color upon a length of cloth; but it is applicable in other
cases where continuous or long lengths of material have to be pressed.
My machine consists essentially of (1) a rising and falling plunger or presser ;
(2) a fixed table or block against which the pressing is effected; (3) mechanism
whereby the material to be pressed is moved forward intermittently between the
plunger and the table, each movement being equal to the width of the pressing face of
the plunger; and (4) a steam heated cylinder over which the material is led before
reaching the plunger; this cylinder will, however, only be required in cases where
the material has to be warmed or softened before pressure.
Having explained the nature and main features of my machine I will describe more
in detail how it can be constructed and for this purpose I will refer to the accom-
panying drawings which represent a pressing machine in which my invention is
embodied. In these drawings Figure 1 is a side elevation of the machine. Figures 2
and 3 are respectively an end elevation and a plan and are drawn to a somewhat
larger scale than Figure 1; the steam heated cylinder and the roller'from which the
roll of cloth is unwound are omitted from these two Figures.
a is a fixed table or pressing block above which is arranged a plunger or presser
having an up and down movement. This movement can be produced in any
convenient manner; the preferred arrangement is that shown in the figures and
consists of excentrics c c on a rotating shaft d,communicating motion through links e e
to cross heads ff which are connected by vertical bars to the plunger b. Four
vertical bars marked respectively g 9 g,and g³ are shown in the figures and all of them
may connect the crossheads ff to the plunger, but in the arrangement' shown the
three bars marked gg.g constitute this connection while the fourth bar g2 is a fixture
to the frame of the machine for the purpose hereinafter described, but it also serves as
a guide to the crosshead and plunger in their up and down movements. At one side
of the press is a steam heated cylinder over which the material A-to be pressed, say
a roll or length of cloth covered with sheets, or pieces of paint composition is led from
a roller (or otherwise). From the steam heated cylinder 'h the cloth is led between
the plunger band. the pressing block a, and its end or the end of a sheet or cloth
connected thereto for the purpose is attached to a travelling' band jarranged at the
delivery side of the pressing mechanism which draws it forward intermittently as
about to be described. Upon a wheel & which is on the shaft d (though it might be
on another shaft) is a crank pin connected by a rod m to an arm n mounted loosely
on the shaft of a ratchet wheel r on which shaft is a pulley p that drives the travelling

band j; this arm n has a pawl q which takes into the ratchet wheel r. The result of
this arrangement is that as the crank pin in the revolution of the wheel k is
approaching the wheel it causes the arin n to push the ratchet wheel r round by
means of its pawl 7, consequently the travelling band j and therefore the length of
paint covered cloth are caused to move a certain distance, that is to say a distance
equal to the width of the plunger b. During this forward movement of the cloth the
plunger is clear of the bed or pressing block a. Then as the crank pin in the
revolution of the wheel k is receding or moving away from the pulley p the arm n
and pawl are drawn back, the pawl riding over the ratchet teeth r; therefore there
is no movement of the cloth and it is during this interval or intermittence of the
movement that the plunger & comes down and presses that part of the material which
is then below it. This intermittent action continues until the whole length of the
cloth or material has been pressed in successive sections. The travelling band j
should be as long as the roll or length of material to be pressed, which in the case of
floor cloths is generally 60 feet. It is preferred not to carry the travelling band j
round a roller on the shaft of the ratchet wheel r, but round a roller driven by a belt
from the pulley p on that shaft as shown, s being the roller driven by a belt t and
pulley from the pulley.p.
is the roller at the other end of the course of the
travelling band j. is the driving shaft of the machine; motion is transmitted
therefrom by a pinion to which gears with internal teeth cut around the wheel k In
order to allow of the pressure being regulated the machine is fitted with a screw
shaft having a.handle y and gearing with screw or worm wheels on the vertical
bars g. By turning the shaft rotation is given to the vertical bars g which are
screw threaded at one part to take into corresponding female threads in the
plunger b; the height of the plunger and consequently the pressure exerted thereby
are regulated.
If it is required to emboss the material the plunger will be engraved or cut
accordingly.
In order that the machine may always indicate the pressure to which it is adjusted
I adopt the following contrivance :-Upon the plunger 6 I fix a curved bar 1 divided
off to indicate on an enlarged scale parts (say hundredths) of an inch, assuming an
inch to be the maximum movement of the plunger. To a piece 2 screwed or firmly
attached to the top of the bar g3 which is a fixture to the frame of the machine I
attach the short arm of a lever 3 pivoted at 4 to a bracket forming part of the
plunger; the long arm of the lever 3 is connected by a link 5 to a hand or indicator 6
which is pivoted at its end to a bracket forming part of the plunger, the connection
between the link and the indicator being near the pivot. The result of this arrange-
ment is that as the plunger moves up or down while the bar g' remains stationary the
extent of the movement is multiplied by the lever 3, link 5 and indicator 6, and is
indicated on the curved bar or scale 1, where it can be easily read.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what i
claim is
'
