PROVISIONAL SPECIFICATION.
An Improved Appliance for Spreading Oil Colour on the Furnishing
Pad used in the Printing of Linoleum, Floor-cloth, and the like
by Means of Hand-blocks.
We, EDWARD OSTLERE, of Forth Works, Linoleum and Floor-cloth Manufac-
turer, and GEORGE FREDERICK COOPER, of 4, Salisbury Street, Engineer, both
in Kirkcaldy, in the County of Fife, do hereby declare the nature of this inven-
tion to be as follows:-
In the printing of floor-cloth and the like fabrics by means of hand-blocks
with oil colour, a furnishing pad is employed for each colour, over which pad
the oil colour is distributed by means of brushes or rollers.
By bringing the printing block on to this pad, sufficient colour is trans-
ferred to its surface.
The present invention relates to the construction of an appliance whereby
the colour is mechanically spread over the surface of the pad by means of rollers
worked by the depressing of a treadle, so effecting a considerable saving of
labour as compared with the older method in which hand brushes or hand rollers
are used.
In one form of our invention we employ a pad and two rollers, the said
rollers being arranged horizontally one above the other and sliding in a guide
fork, running on rails at each side of the pad: a shallow colour trough parallel
to the axis of the rollers is also arranged at each or one end of the pad, and a
suitable system of levers and a treadle are provided.
When at rest the lower of the two rollers is partially immersed in the oil
colour contained in one of the troughs. On the treadle being depressed the
levers are actuated, causing the rollers, by means of the guide fork and suitable
bearing-wheels over the said rails, to traverse the surface of the pad, until at
the end of their course the lower roller dips into the colour contained in the
second trough.
On the treadle being released a counter-balance weight (or a suitable spring
arrangement) causes the rollers to traverse their course in the opposite direction.
In this way an even layer of colour is transferred to the surface of the pad,
its amount depending on the distance between the two rollers (regulated by the
bearing-wheels) and on the distance of the rollers from the surface of the pad
(regulated by rails).
In some cases we prefer to construct the lower of our said furnishing rollers
grooved at right angles to its axis of rotation, so that it can convey more colour
and thus give a more liberal supply to the surface of the pad.
The rollers may be of metal, wood, "printer's jube," or other suitable material.

Pad used in the Printing of Linoleum, Floorcloth, and the like by
Means of Hand-blocks.
We, EDWARD OSTLERE, of Forth Works, Kirkcaldy, in the County of Fife,
Linoleum and Floorcloth Manufacturer, and GEORGE FREDERICK COOPER, of
4, Salisbury Street, Kirkcaldy, in the County of Fife, 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:-
In the printing of floorcloth and the like fabrics by means of hand-blocks
with oil colour for each shade, a furnishing pad is employed, over which the
oil colour is as evenly as possible distributed by means of brushes or small
hand rollers. By bringing the printing blocks on to the surface of this pad,
sufficient colour is conveyed to them for the impression.
The present invention relates to the construction of an appliance whereby
the colour is mechanically spread over the surface of the pad by means of rollers
or a roller, of nearly the same length as the pad, worked by depressing a treadle
with the foot, or by means of a hand rail. In this way a considerable saving
of labour is effected, as compared with the older method in which hand brushes
or small hand rollers are used.
One form of our invention consists in an arrangement of a pad, with two
colour rollers one above the other, the said rollers sliding in the guide fork
of a slotted lever and running on bearing wheels over rails fixed at each side
of the pad a shallow trough for the colour, parallel to the horizontal axis of
the rollers, is also arranged at each or one end of the pad, and a suitable system
of levers and treadle are provided.
In another form of our invention we slightly vary the position of the said
rollers, and the treadle is preferably dispensed with, the rollers being actuated
by means of a suitable hand rail.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation, Fig. 2 an end elevation, and Fig. 3 a plan, of one
form of our invention; the top roller being removed in Fig. 3.
Fig. 4 is a side elevation, and Fig. 5 an end elevation, of another form of
our invention.
Fig. 6 is a side elevation (enlarged) of the roller arrangement in Figs. 4
and 5.
Fig. is a plan (in section) of Fig. 6.
Similar letters of reference are employed to indicate similar parts throughout
the several views.
A is the furnishing pad, which is carried on the table B mounted upon
wheels C.
D is the main furnishing roller with bearing wheels E E, F is the 'doctor'
roller with bearing wheels G G, and H H are the rails.
I is the forked or slotted lever, which is pivotted at J.
K is the treadle, connected by rod L to the lever I, and having counter-balance
weight M or springs N.
00 are the colour troughs.
PP are small pawls with buffer springs Q Q.
Referring to Figs. 1, 2, and 3, the operation of the apparatus is as follows:

page_text: tained in one of the troughs O. On the treadle K being depressed, the rod L
is actuated, causing the rollers D and F, by means of the forked or slotted
lever I and bearing wheels E and G, to run along the rails H H and so traverse
the surface of the pad A, until at the end of their course the said roller D dips
into the colour contained in the second trough O. The pawls P P, together
with their springs QQ, prevent unnecessary jar of the rollers D F at each end
of their course. On the foot being removed from the treadle K, the weight M
or the spring arrangement N (or both) causes the rollers to traverse their course
in the opposite direction. In this way an even layer of colour is transferred
to the surface of the pad A, its amount depending on the distance between
the rollers D and F (which is regulated by the bearing wheels E and G), and
on the distance of the roller D from the surface of the pad A (determined by
the rails HH).
The
Referring to Figs. 4, 5, 6, and 7: in this the treadle arrangement is dispensed
with, and a hand rail R, fixed at the top of the lever I, is substituted.
'doctor' roller F is removed from the slotted lever I and is placed in front
of the main furnishing roller D, its bearing wheels G G being replaced by
links S S (connecting it with the main roller D) and by eccentrically mounted
cam or cams T riding on the rails H H and having a short movement (limited
in both directions by the radial slot T¹) about its pivot. The set screw U allows
of the roller F being fixed, and the distance between the pad A and the said
'doctor' roller F may be regulated by an adjusting bolt and nut V in a slot W.
Only one colour trough O is employed.
The operation is as follows: The furnishing roller D is brought by means of
the hand rail R to one end of the pad A, and is made to dip into the trough O
containing the colour. It is then brought forward over the surface of the
pad A, to which it transfers the colour. During the forward motion the cam T
takes its backward position in the slot T¹ and raises the 'doctor' roller F
sufficiently above the surface of the pad so as to miss the colour on the said
pad, or not materially interfere with the amount of same. After traversing
the pad the roller is returned to its original position, the pawl P with its
spring serving as a buffer; during this return motion the cam T takes its
forward position in the slot T¹ and so causes the 'doctor' roller F to approach
nearer to the surface of the pad A, thereby distributing the colour evenly on
the said pad.
In this way the quantity of colour transferred to the pad A by the roller D
is regulated and evenly distributed, so that the printing block when brought
on to the surface of the pad acquires a uniform layer of colour.
We do not restrict ourselves to the employment of the fixed roller 'doctor.'
as a blunt knife 'doctor' may be used in its place, although we find that the
arrangement described gives the best results.
Neither do we restrict ourselves to the hand rail method of propulsion (which
is applicable to both forms of the invention), as the roller may be also effec-
tively actuated by the treadle and levers as before described.
Still on account
of cheapness and simplicity we prefer to use the hand rail.
The rollers in both forms of the invention may be constructed of metal, wood,
or other suitable material.
Sometimes it is found necessary to make the main furnishing roller grooved,
so that it may give a more liberal supply of colour to the pad.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
(1) In the printing of linoleum, floorcloth, and like fabrics by means of
hand-blocks, the method of and apparatus for spreading the oil colour on the
furnishing pad, substantially as shown and described.
(2) In the printing of linoleum, floorcloth, and like fabrics by means of

page_text: hand-blocks, the mechanism consisting of a furnishing pad A, a furnishing
roller D) with bearing wheels E, a slotted lever I hinged at the bottom of the
table B, an upper horizontal roller F with bearing wheels G, the side rails H,
and the colour trough or troughs 0, such mechanism being actuated either by
a simple hand rail R or by a treadle arrangement K, substantially as shown
and described.
(3) In the printing of linoleum, floorcloth, and like fabrics by means of
hand-blocks, the mechanism consisting of a furnishing pad A. a furnishing
roller D with bearing wheels E, a slotted or forked lever I hinged at the bottom
of the table B, the side rails H, a fixed roller (or knife) doctor F with link
attachments S and cams T, and the colour trough O, such mechanism being
actuated either by a simple hand rail R or by a treadle arrangement K, sub-
stantially as shown and described.
