WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex, Patent
Agent. "IMPROVEMENTS IN MACHINES FOR APPLYING GROUND COLOR TO PAPER
HANGINGS AND OTHER MATERIALS." [A communication from abroad by Thomas
Smith, of West New Brighton, in the County of Richmond, State of New York,
United States of America.]
The object of this Invention is to apply the ground color to paper hangings and
other materials rapidly and uniformly.
The Invention consists in a grounding machine in which the rotary brushes that
distribute the color receive a longitudinal movement by eccentrics and levers to
ensure a uniform application of the color to the paper; it also consists in attaching
the fulcrum studs of the levers to the bearings of the brushes, so that the brushes
can be adjusted without disarranging the connection between the said levers and
brushes, as will be hereinafter fully described.
The frame of the machine has bearings in its upper part to receive a shaft to
which is attached a large cylinder around which the paper is passed to be colored.
A roller receives the coloring matter from a vat, in which vat the lower part of
the said roller revolves. The journals of the roller revolve in bearings attached to
the lower forward part of the frame. In bearings attached to the forward part of
the frame revolves a cylindrical brush in such a position that it will be in contact
with the roller to receive color, and in contact with the lower forward part of the
cylinder to apply the color to the paper passing around the said cylinder.

page_text: Beneath the middle part of the cylinder is placed a second cylindrical brush in
such a position as to be in contact with the paper passing around the said cylinder.
The journals of the brush revolve and slide in bearings placed in vertical slots in
arms or hangers formed upon or attached to the frame. The bearings are raised
and lowered to take up the wear, and to adjust the brush to bear with any desired
pressure against the paper by set screws passing in through the lower ends of the
hangers and resting against the lower sides of the said bearings. The bearings are
secured in any position into which they may be adjusted by set screws passing in
through a side of the hangers, and resting against the side of the said bearings.
Beneath the rear lower part of the cylinder before mentioned is placed a third
cylindrical brush in such a position as to bear against the paper passing around
the said cylinder. The journals of this brush revolve and slide in bearings attached
to the frame. The bearings of the color roller and the first and third brushes are
slotted vertically to receive the bolts that secure the said bearings to the frame
so that the brushes can be raised and lowered to take up the wear, and to cause
them to bear against the paper with any desired pressure.
The driving shaft, to which motion may be given from any convenient power,
revolves in bearings attached to the top of the frame. To the end of the shaft is
attached a beveled gear wheel, the teeth of which mesh into the teeth of a beveled
gear wheel attached to the end of a longitudinal shaft, which also revolves in
bearings at the top of the frame, and to the said shaft is attached a gear wheel,
the teeth of which mesh into the teeth of a large gear wheel attached to a shaft
that carries the paper cylinder. To the other end of the longitudinal shaft is
attached a pulley around which passes a belt, which belt also passes around pulleys
attached to the journals of the brushes. The belt between the pulleys is carried
upward and passed over guide pulleys pivoted to the frame. With this construction
each of the pulleys is placed in a loop of the belt, so that the longitudinal movement
of the brushes will not throw the belt off its pulleys. This construction also gives
the belt a longer bearing upon the pulleys so that the brushes will be revolved
with certainty. To the driving shaft is also attached a pulley around which passes
a belt which also passes around a pulley attached to the end of a shaft revolving
in bearings at the lower part of the frame, and to the said shaft are attached or
upon it are formed two eccentrics, with which are connected by eccentric straps or
other suitable means the ends of eccentric bars, whose other ends are pivoted to
the lower ends of levers, the upper ends of which are forked and rest between two
flanges formed upon or attached to the ends of the journals of the brushes. The
friction between the forked ends of the levers and the flanges of the brush journals
is lessened by small wheels or rollers placed upon pins attached to the said ends.
The levers are pivoted to supports attached to the bearings in which the journals
of the second and third brushes revolve so that the adjustment of the said bearings
will not affect the connection between the levers and the flanged journals of the
brushes. With this construction the color distributing brushes will receive a
longitudinal vibratory movement while being rotated, so that the color will be
evenly distributed over the paper.

WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex, Patent
Agent. "IMPROVEMENTS IN MACHINES FOR APPLYING GROUND COLOR TO PAPER
HANGINGS AND OTHER MATERIALS." A communication from abroad by Thomas
Smith, of West New Brighton, in the County of Richmond, State of New York,
United States of America.
The object of this Invention is to apply the ground color to paper hangings and
other materials rapidly and uniformly. The Invention consists in a grounding
machine in which the rotary brushes that distribute the color receive a longi-
tudinal movement by eccentrics and levers to ensure a uniform application of the
color to the paper; it also consists in attaching the fulcrum studs of the levers to
the bearings of the brushes so that the brushes can be adjusted without
disarranging the connection between the said levers and brushes, as will be
hereinafter fully described.
In the accompanying Drawings Figure 1 is a front elevation of the improved
machine; Figure 2 is a sectional side elevation of the same taken through the
line, Figure 1; Figure 3 is an elevation of one side of the machine; Figure 4
is an elevation of the other side of the machine. Similar letters of reference indicate
corresponding parts.
A represents the frame of the machine which has bearings in its upper part to
receive a shaft B to which is attached a large cylinder C around which the paper
is passed to be colored; D is a roller which receives the coloring matter from a vat,
in which vat the lower part of the said roller D revolves. The color vat is not
shown in the Drawings, as there is nothing new in its construction. The journals
of the roller D revolve in bearings E attached to the lower forward part of the
frame A. In bearings E attached to the forward part of the frame A revolves a
cylindrical brush F in such a position that it will be in contact with the roller D
to receive color, and in contact with the lower forward part of the cylinder C to
apply the color to the paper passing around the said cylinder C. Beneath the
middle part of the cylinder C is placed a second cylindrical brush G in such a
position as to be in contact with the paper passing around the said cylinder C.
The journals of the brush G revolve and slide in bearings H placed in vertical
slots in arms or hangers I formed upon or attached to the frame A. The bearings H
are raised and lowered to take up the wear and to adjust the brush to bear with
any desired pressure against the paper by set screws J passing in through the
lower ends of the hangers I and resting against the lower sides of the said
bearings H. The bearings H are secured in any position into which they may be
adjusted by set screws K passing in through a side of the hangers I and resting
against the side of the said bearings H. Beneath the rear lower part of the
cylinder C is placed a third cylindrical brush L in such a position as to bear against
the paper passing around the said cylinder C. The journals of the brush L revolve
and slide in bearings E attached to the frame A. The bearings E of the roller D
and the brushes F, L, are slotted vertically to receive the bolts that secure the said
bearings Ę to the frame A, so that the brushes F, L, can be raised and lowered to
take up the wear and to cause them to bear against the paper with any desired
pressure. M is the driving shaft, to which motion may be given from any
convenient power, and which revolves in bearings attached to the top of the
frame A. To the end of the shaft M is attached a bevelled gear wheel N, the
teeth of which mesh into the teeth of a bevelled gear wheel O attached to

page_text: the end of a shaft P. The shaft P revolves in bearings at the top of the frame A,
and to the said shaft is attached a gear wheel Q, the teeth of which mesh into the
teeth of a large gear wheel R attached to the shaft B that carries the cylinder ˚C.
To the other end of the shaft P is attached a pulley S around which passes a
belt T. The belt T also passes around pulleys U, V, W, attached to the
journals of the brushes F; G, L. The belt T between the pulleys U, V, W, is
carried upward and passed over guide pulleys X, Y, pivoted to the frame A. With
this construction each of the pulleys .U, V, W, is placed in a loop of the belt T so
that the longitudinal movement of the brushes will not throw the belt off its
pulleys. This. construction also gives the belt T a longer bearing upon the
pulleys U, V, W, so that the brushes will be revolved with certainty. To the
driving shaft M is also attached a pulley Z. around which passes a belt a, which
also passes around a pulley b attached to the end of a shaft c revolving in bearings
attached to the lower part of the frame A, and to the said shaft are attached, or
upon it are formed, two eccentrics d with which are connected by eccentric straps
or other suitable means the ends of bars e. The other ends of the eccentric bars e
are pivoted to the lower ends of levers f, the upper ends of which are forked and
rest between two flanges formed upon or attached to the ends of the journals of
the brushes G, L. The friction between the forked ends of the levers f and the
flanges of the brush journals is lessened by small wheels or rollers placed upon
pins attached to the said ends. The levers ƒ are pivoted to supports g attached
to the bearings E, H, in which the journals of the brushes L, G, revolve, so that
the adjustment of the said bearings E, H, will not affect the connection between
the levers and the flanged journals of the brushes L, G. With this construction
the color distributing brushes G, L, will receive a longitudinal vibratory
movement while being rotated, so that the color will be evenly distributed over
the paper.
Having described the nature of the said Invention and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
hereinbefore in part recited Letters Patent is,
1st.. In a grounding machine, the combination with the color distributing
brushes G, L, of the levers f and eccentrics d, substantially as herein shown and
described, whereby a longitudinal movement is given to the said rotary brushes, as
set forth.
2nd. In a grounding machine, the combination with the bearings E, H, of the
studs g attached to the said bearings, substantially as herein shown and described,
whereby the brushes can be adjusted without changing the relative positions of the
levers and brushes, as set forth.
In witness whereof, I, the said William Clark, have hereunto set my hand
and seal, this Fifteenth day of February, A.D. 1882.
