I, ALFRED SMITH, of Hackney, in the County of Middlesex, Engineor, do
hereby declare the nature of tho said Invention for "IMPROVEMENTS IN
MACHINERY FOR APPLYING PASTE AND OTHER LIQUID, ADHESIVE MATERIAL, COLOR,
AND PAINT TO PAPER AND OTHER SUBSTANCES," to be as follows:-
The object of the first part of my Invention is the arrangement of
machinery for applying paste or other material as aforesaid to paper and
other substances, over which the brush is made to travel, while the substance
is stationary. At the top of the inside of each sido of the frame of the
machine I place a continuous grooved rack, in which works a toothed wheel
on each end of a circular brush, the hairs of which are fixed at an angle
extending outwards in opposite directions from the centre. To this brush is
fixed one end of a connecting rod, and to this same end of the connecting
rod is also fixed, by brackets or otherwise, a paste box and brush suspended
over, the hairs of which work into the hairs of the circular brush before
mentioned. This paste box and brush are made in the following manner :-
I take a wooden box of the required size, in the bottom of which I bore a
number of conical holes, and turn a number of hollow cones to fit the same ;*
round. these hollow cones I fix the hairs of the paste brush, and then fasten
them in the holes in the bottom of the box before mentioned; the box being
filled with paste or other liquid or semi-liquid material, it flows through the

page_text: holes at the bottom on to the hairs of the brush, and the circular brush
revolving supplies itself with paste by coming in contact with the hairs of
the pasto brush suspended above it. The other end of the connecting rod
before mentioned is fastened to ono end of a lever by a stud, upon which it
works free; the other end of the lever is fastened to the bottom of the frame
of the machine, and is allowed to work free on a stud. This lover receives a
reciprocating motion from a connecting rod, fixed at one end to a crank on
the driving shaft of-the machine, the other end being fixed at any convenient
place ou the lever according to the length of stroke required. I cause the
table on which the work is pasted to descend as it accumulates by means of
a rod striking a ratchet wheel which turns a screw to which the table is
fixed.
The machine being now ready for work, and the paper and cloth being
placed in order, the workman proceeds as follows:-A sheet of paper is
placed on the table of the machine, motion is given to it, and the wheel
brush is pulled along the top of the paper on the table, the brush being made
to revolvo as it travels by pinions fixed on its ends, which gear into the rack.
When the brush has gone over the sheet to be pasted, the connecting rod
attached to the brush strikes against an inclined plane, which works upon a
fulcrum at its highest part, and the brush is raised from the paper by being
drawn up this inclined plane. When the brush is at the height required,
the inclined plane shifts its position and becomes a horizontal plane, the
brush then returns in the top of the grooved rack, and during its return 'the
tablo is lowered as much as is wanted by tho ratchet or other means, and
.the workman places another sheet of paper on the table as before, when the
brush again comes into operation, and so on. Sometimes I dispenso with
the upper portion of the rack, and then the revolving brush acts both in 'tho
forward and return strokes.
My Invention consists, secondly, in arrangements of parts of machinery
whereby the paper or substance to be pasted, colored, or painted is made to
travel under a brush and supply box similar to 'those before described. The
brush is free to revolve only, without travelling over the paper or other sub-
stance, as in the former case. I take an endless tablo composed of slats
hinged or otherwise held together. This table is caused to travel by means
of a polygonal drum driven by a main driving wheel, and to carry the
substance to be pasted, colored, or painted under the rovolving brush.
My Invention consists, thirdly, in fitting a brush with supply box as before
än such manner that it may describe circles, and spread the paste or other
material evenly on the papor or other substanco under operation. I connect

page_text: a rod to the box, and centro it upon a stud in a fixed rail above. I unite an
eccentric or crank to the top of the rod, and by driving the crank I obtain a
circular motion in the brush.
I do not confine myself to the use of brushes filled with hair as before
described, as brushes filled with hair in the ordinary manner may be used.
