1, JOHN WRIGHT, of 13 Townsend Place, Kirkcaldy, in the County of Fife, North
Britain, Floorcloth Manufacturer, do hereby declare the nature of this Invention to
be as follows, that is to say :-
My said Invention relates to machinery of the kind described in my Patent Speci-
fications, No. 2749 of 1870, and No. 8881 of 1884; and consists of improvements in
various arrangements and details whereby the machinery is made to operate more
accurately and satisfactorily.
Rollers with raised printing surfaces are used in the machinery to which my Inven-
tion relates; and an entire piece of the fabric to be printed is stretched on a large
cylinder or drum which is of a width corresponding to the greatest width of fabric
intended to be printed on the machine.
"
Some of the present improvements are designed to facilitate the printing of borders
by a separate set of printing rollers in combination with various widths of centre or
filling" work. When comparatively narrow widths with borders are to be printed
they may be printed on separate pieces of fabric, stretched side by side on the
drum, or the separate widths may be printed side by side on a single wide piece of
fabric.
The printing rollers are carried by two frames, the border frame and the filling
frame, which are fitted to slide upon a guide bench extending in front of and parallel
to the drum. The filling frame is made with two gables or end standards the printing
rollers on it being supported at both ends; but the border frame is made with a
single standard, and the border rollers, which are comparatively short, are overbung
on the side of the frame next the filling frame, to permit of the border rollers, being
moved near to the filling rollers. The filling and horder frames are moved along the
guide bench by means of a continually rotating screw shaft, each frame being pro-
vided with a pair of half nuts and engaging and disengaging gear, which is partly
automatic, for applying and stopping the motion as required. The shifting of the

page_text: filling and border frames (which are of course stationary whilst printing a circuit of
the drum) is controlled by blocks suitably arranged in a line under the frames, such
blocks having in them separate holes for the two frames. When either frame is being
shifted along the guide bench a pin carried by it drops into a hole on the proper
position being reached, and this motion of the pin brings about the disengagement of
the half nuts and stoppage of the motion. The frame shifting motion may also be
started automatically by a tappet which comes into action when the drum completes a
printing circuit.
The printing rollers are carried by bearing blocks which are adjustable in guides in
the frames and are provided with the usual color-supplying apparatus. The rollers
are driven by bevil wheels on their spindles, these bevil wheels having in gear with
them bevil wheels on a series of nearly vertical shafts which are themselves driven by
bevil wheels from a single shaft on each frame. The nearly-vertical shafts are held
in spherical hearings and are made telescopic to accommodato any adjustment move-
ment of the printing rollers.
The machine is driven by a special engine which operates through a pinion on a large
internally toothed wheel on the drum, with which latter there is in gear another
pinion for driving the printing rollers. The gearing through which the motion is
transmitted to the printing rollers comprises engaging and disengaging clutches which
instead of being of the ordinary kind, consist in each case of a pair of disks with
pins on one to engage in holes in the other, whereby more accurate agreement
between the movements of the drum and printing rollers is obtained.
The filling rollers are made by preference of comparatively short lengths, the
border rollers being however still shorter; and the lengths aro arranged so that the
widths most generally required in the trade can be conveniently made up by
printing side by side various numbers of widths each equal to the length of the
rollers.

page_text: I, JOHN WRIGHT, of 13 Townsend Place, Kirkcaldy, in the County of Fife, North
Britain, Floorcloth Manufacturer, 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, that is to say :-
My said Invention relates to machinery of the kind described in my Patent
Specifications, No. 2749 of 1870, and No. 8881 of 1884; and consists of improve-
ments in various arrangements and details whereby the machinery is made to operate
more accurately and satisfactorily.
Rollers with raised printing surfaces are used in the machinery to which my Inven-
tion relates; and an entire piece of the fabric to be printed is stretched on a large
cylinder or drum which is of a width corresponding to the greatest width of fabric
intended to be printed on the machine.
Some of my present improvements are designed to facilitate the printing of borders
by a separate set of printing rollers in combination with various width of centre or
filling" work. When comparatively narrow widths with borders are to be printed
they may be printed on separate pieces of fabric stretched side by side on the drum,
or separate widths may be printed side by side on a single wide piece of fabric.
The printing rollers are carried by two frames, the border frame and the filling
frame, which are fitted to slide upon a guide bench extending in front of and parallel
to the drum. The filling frame is made with two gables or end standards the printing
rollers on it being supported at both ends; but the border frame is made with a
single standard, and the border rollers, which are comparatively short, are overhung
on the side of the frame next the filling frame, to permit of the border rollers being
moved near the filling rollers.
And in order that arrangements hereinbefore referred to, together with various
accessory details, may be properly understood I hereunto append four sheets of
explanatory drawings to be hereinafter referred to and representing floorcloth
printing machinery as made with my improvements.
Figures, 1, and 2, on sheets, 1, and 2 of the drawings are elevations as at right

page_text: angles to each other; and figure, 3, on sheet, 3, is a sectional plan corresponding
to figure, 2. Figures, 4, to 7, on sheet, 4, are enlarged detail views of cortain
engaging gear. In these drawings the saine reference letters and numerals are
used to mark the same or like parts wherever they are repented.
In figure, 1, there is shown a small part of the large cylinder or drum, D, on
which the fabric to be printed is stretchoi, this drum being, as formerly, made with a
gap or depression, G, which faces the printing rollers, R, as shown, when the
rollers are being moved along across the width of the drum. The filling frame, F,
with its printing rollers, R. is shown in side elevation upon the bench, A, on which
it is supported and along which it slides into its various positions. In figures, 2, and 3,
the border frame, B, is shown as well as the filling frame, the rollers, S, of the
border frame being overhung upon a single gable, B, whilst the filling rollers, R, are
carried between two gables, F.
The filling and border frames, F, B, are moved along the guide bench, A, by means
of a continuously rotating screw shaft, (', each framo being provided with a pair of
half nuts, E. and engaging and disengaging gear, which is partly automatic, for
applying and stopping the motion as required. Figures, 4, and 5, are enlarged
sectional elevations as at right angles to each other showing the half-nut arrange-
ment and figures, 6, and 7, are horizontal and vertical sections. The half nuts, E,
are blocks fitted to slide horizontally in guides on opposite sides of the screw
shaft, C, and are connected by pairs of links, 10, to crossheads, LI, on a two-armed
lever, 12, which is fast on a rocking spindle, 13, having on one end of it a weighted
lover, H, made with a short arm shaped into a crosshead, J, at its end.
The shifting of the filling and border frames, F, B, (which are of course stationary
whilst printing a circuit of the drum) is controlled by hollow blocks, K,
(figures, 1, and 8) suitably arranged in a line under the frames. F, B. being bolted
to the inner side of one top side of the bench, A, such blocks, K, having holes in
them in different positions or lines for the two frames. The hotes referred to are
in the tops of the blocks, K, and there are also corresponding holes in the bottoms;
and in the inside of each block there is a headed pin, L, which is movable in the
bottom hole. For entering the respective holes in the blocks, K. each frame, F, B,
is provided with a pin, M, working vertically in a strong guide formed in the sole
of the frame, such pin, M, being connected to a weighted over, N. which gives the
pin a downward pressure so as to drop down in a hole in the block, K. when brought
over the hole by the movement of the frame along the guide hench. A. When the
pin, M, thus enters the hole in a block, K, it forrees down the internal pin. L. which
then protruding below the bottom of the block nets on the crosshead, ), of the
lover, H, and turns that lever in a manner to make the half nuts, E, move out of
gear from the screw shaft, C. Whilst either frame, F, B, is moving along its pin, M,
is prevented from dropping between the blocks, K, by bars or rails, P. extending
from each block to the next. The lever, N, is made with three arins, one being
for moving it by hand, the second, the weighted one being for acting on the pin, M,
and the third being for transmitting an automatic action derived from the drum, D.
For this purpose the third arm of each lever, N, is connected by a link, 14, to a
lover, 15, held by a bracket, 16, bolted to the frame, F, or B, the lever, 15, being
made with a long boss loose on a square shaft, 17, along which shaft, the lever, 15,
is carried by the frame. The squaro shaft, 17, is carried in bearings, 18, at the
ends of the bench, A; and near the right-hand end, figuro, 2, has fast on it a
lever, 19, connected by a rod, 20, to one arm of a bellerank lever, 21, the other arm
of which is connected by a rod, 22, to a lever, 23, on a shaft, 24, extending hori
zontally to a position near the lowest part of the drum, D. Near the inner end of
the shaft, 24, there is fast on it a lovor, 25, which with other parts is indicated by
dotted lines in figuro, 2, and which is connected by a rod, 26, to a lever, 27, on the
outer end of a short shaft, 28, having on its innor end a lever, 29, which is acted on
by a pin, 30, on the drum, 15, when the drum comos round into the position with
its gap, G, facing the printing rollers, R. The action caused by the pin, 30, of the

page_text: drum. D, through the connections which have been described, moves the lever, N,
and through it other parts so as to engage the half nuts, E, with the screw shaft, C,
and thereby start the movement of the frames, F, B, along the bench, A. Each
link. 11, connected to the levers, N, is made with a slot and gab notch and can be
moved to disengage the notch from the lever, N, to prevent that lever being moved
by the automatic action from the drum when the frame, F or B, is not to move along
the guide bench, A. The pin, 30, on the drum, D, corresponds to a similar pin on
the drum of my former machine described in the earlier Specification No. 8881
of 1884, hereinbefore referred to, and like the former pin, also causes a brake to act
on the drum and stop its motion, and brings about the shifting of the driving belt on
to the loose pulley. In the machine shown in the drawings of my present Specifica-
tion the belt-shifting fork, 31, is below the pulleys, 32, (figure, 2) on a horizontally
sliding bar, 31 which is connected by a rod, 34, to a lever, 35, on the shaft, 24,
hereinbefore referred to.
The printing rollers, R, S, are carried by bearing blocks, 36, which are adjustable
in guides in the frames, F, B, and are provided with the usual color-supplying
apparatus, which, however is not shown in the drawings. The rollers are driven
by bevil wheels, 37, on their spindles, these bevil wheels having in gear with thom,
bevil wheels on a series of nearly vertical shafts, 38, which are themselves driven by
bovil wheels, 39, from a single shaft, 40, on each frame, F, B The nearly vertical
shafts, 38, are held in spherical hearings, 41, 42, and are made telescopic to accom
modate any adjustment movement of the printing rollers, the parts of each tele-
scopic combination being made to turn together by being square or by means of a
groove and feather. Each shaft, 40, has its inner end carried by a bracket, 43,
formed on or fixed to the frame, F. B, and this bracket is also fitted with bearings
for a tube, 44, geared to the shaft, 40, by bevil wheels, 45, and for a clutch tube, 46,
which can be engaged with the tube, 44, and which is made to rotate by a shaft, 47,
by means of a groove and key. The shaft, 47, passes through both tubes, 44, 46,
or they are carried along it when the frames, F, B, are moved along the bench, A.
The clutch tube, 46, is engaged and disengaged by means of a bellerank lever, 48,
connected by a rod, 49, to a hand lever, 50. The shaft, 47, for driving the
printing rollers, extends from end to end of the machine, and at one end is geared
by means of a pinion, 51, with a spurwheel, 52, loose on a shaft, 53, which at its
inner end has fast on it a pinion, 54, for gearing with a ring of internal teeth on the
end of the drum, this gearing being indicated by dotted circles in figure, 1. For
engaging the spurwheel, 52, with the shaft, 53, a clutch, 55, is provided with
studs on its face to enter holes in a plate, 56, formed in the same piece with or fixed
to the wheel, 52. The clutch, 55, is movable by a bellerank lever, 57, connected by a
rod, 8, to a lever on a short shaft having on it a hand lever, 59.
The machine is by preference driven by a special engine, which is not shown, but
which, directly or through gearing, gives motion to a shaft, 60, not shown in figure, 3.
This shaft, 60, by means of gearing which is not shown drives the drum, D, a pinion
acting on the ring of internal teeth hereinbefore referred to. The shaft, 60, has also
on it a pulley, 61, figure, 2, which by means of a belt and pulleys, 62, drives a short
shaft, 63, and this by means of a pinion. 64, and spurwheel, 65, drives the screw
shaft, provided for moving the frames, F, B, along the bench, A, as hereinbefore
explained. To prevent abrupt shock when the screw shaft, (, becomes engaged with
the half nuts, E, of the frames, F, B, the shaft, C. is allowed end play in its bearings
this play being controlled by helical springs, 66, figure, 3. placed on it on opposite
sides of a bearing each spring being between a collar fixed on the shaft and a loose
collar in contact with the bearing.
The filling rollers, It, are made by preference of comparatively short lengths, the
border rollers, S, being however still shorter; and the lengths are arranged so that
the widths most generally required in the trade can be conveniently made up by
printing side by side various numbers of widths each equal to the length of the
rollers.

page_text: 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 :-
1. The improved combination of parts forming as a whole the machine for printing
floorcloths and similar fabrics, substantially as herein before described.
2.-The combined gearing, engaging devices, and automatic appliances connected
with the movements of the frames carrying the printing rollers substantially as
bereinbefore described.
3. The combination with the larga drum of two printing-roller frames one with
ordinary rollers and the other with overhung border rollers, substantially as herein-
before described.
4.-The combination of the gearing for driving the printing rollers comprising
telescopic shafts in spherical bearings to accommodate the adjusting movements of
the rollers, substantially as hereinbefore described.
