or other powder, and around which is a series of rollers for distributing
the powder and brushing the sheets of paper or other material, the
sheets are delivered to a fly frame and laid on a table with the printeḍ
side upwards; the ends of the drum fit into recesses in the side frames
to prevent the powder falling between them, and the feeding roller is
provided with a doctor the position of which can be adjusted to supply
more or less powder to the paper or other material, the brushing rollers
are all geared up with wheels and revolve in the contrary direction to
that of the drum, and troughs are applied to the rollers to catch the
superfluous powder that they may use it up over again, a brush is
applied to the last roller that it may effectively clean the sheet, and the
rollers work in eccentric bushes to facilitate the adjustment.

(amongst others) that we, the said James Salmon and John Brownhill,

page_text: our executors or administrators, by an instrument in writing under our, -
or their, or one of our or their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office, within six calendar months next and
immediately after the date of the said Letters Patent..
NOW KNOW YE, that we, the said James Salmon and John Brownhill,
do hereby declare the nature of our said 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) :-
Our Invention consists of an improved combination of machinery for
applying the bronzing or other powder to the sheets of paper or other
materials for distributing the powder and brushing the sheets of paper
or other materials, and for delivering them on to a table with the printed
side upwards.
And in order that our Invention may be fully understood and readily
carried into operation we will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.
Fig. 1 is an elevation of our improved machinery; Fig. 2 is a transverse
section, and Fig. 3 an end view of the same; Figs. 4, 5, and 6 are
detached views of parts of the same.
a, a, are the two side frames of the machine to which are fixed the
bearings for the axle of the drum b which is driven by the pinion c³,
on the driving shaft c, the said pinion gearing into the carrier
pinion which drives the wheel 1 fixed to the axle of the drum b. The
pinion c³ on the shaft c gears into the wheel & loose on the axle of the
drum b, and this wheel revolves about three times faster than the drum,
but in the contrary direction. Above the drum 6 is the hopper d,.
containing the bronzing or other powder, the hopper consists of an.
inclined metal or other plate at the bottom of which is the feeding
roller e which is covered with plush or other suitable material, this roller
has an intermittent motion imparted to it by one or more pins
projecting from the wheel b', and these pins act on the two arms ƒ of.
the catch lever f¹, to which is jointed the catch f, which takes into the .
teeth of a small ratchet wheel fixed to the axle of the feeding roller e. ·

page_text: •
By this arrangement every revolution of the wheel 6' imparts a partial
rotary motion to the feeding roller and brings forward a portion of the
bronzing or other powder, and the amount of rotary motion can be
reduced by withdrawing a pin 6* from the wheel b'. Every time the catch
lever has been acted upon it is brought back to its original position
by the weighted arm f³. Below the feeding roller e is the distributor g,
consisting of a vibrating board covered with plush or other suitable
material by which the powder brought forward by the feeding roller is
distributed evenly over and rubbed on the prepared surface of the paper
or other material passing around the drum. The distributor is moved
to-and-fro by a grooved cam 9¹ on the shaft 92, a stud projecting from
the distributing board taking into the groove of the cam, the board is
supported on links g³, as shewn best in Fig. 3. Under the distributor g is
the roller, which is covered with leather, cloth, or other suitable
material, and below the roller h are three or other convenient number
of rollers marked i, j, and k, which are covered with plush or other
suitable material, these rollers are all set so as to act lightly on the
surface of the paper or other material passing over the drum, and they
revolve rapidly in the contrary direction to the drum at their points of
contact, being driven by the wheel 6 gearing into pinions as shewn by
dotted lines in Fig. 1. The superfluous powder is scraped off the surface
of the rollers i, j, and k, by thin blades of metal or other agents, as
shewn in Fig. 2, and the powder that escapes or is scraped off falls into
the tray 1, fitting in the bottom of the chamber in which the drum
revolves.
After the bronzing or other powder has been applied to the paper or
other material and distributed evenly over its surface and well rubbed
by the machinery above described, the paper or other material is cleaned
by the two rollers m and n, both of which are covered with long plush
or other suitable material; both these rollers are driven rapidly in
the directions of the arrows upon them, the roller' m by the pinion c³
on the driving shaft c gearing into the pinion m³, to which is fixed the
friction pulley m³, which gives motion to a small pulley covered with
india-rubber or other suitable material on the axle of the roller m; and
the roller n is driven in the same manner by the wheel b³, gearing into
the pinion n', and by the friction pulley n³ driving a small pulley on
the axle of the roller n. These rollers m and n are provided with thin
blades of metal or other agents to keep their surfaces clean, and they

page_text: effectually remove any loose particles of powder and prepare the paper
before it is released from the drum about three-fourths of the circum-
ference of the drum, and all the parts above described are boxed up to
prevent the escape of the powder into the room by the top lid o, side o¹,
inner cover o*, bottom o³, and front o³, or in any other convenient manner.
The feeding table p, on which the printed or prepared sheets of paper
or other material to be operated upon are laid, is placed by preference in
a slightly inclined position, as shewn in Fig. 1, and the attendant pre-
sents each sheet separately to the drum; the edge of the sheet is stopped
and kept square by the fingers p¹, fixed to a shaft; these fingers are
raised and lowered by the cam 65 fixed to the wheel b', as shewn by
dotted lines in Fig. 2, the cam acting on the bowl of the lever p², fixed
to the shaft of the fingers. The drum bis provided with a gripper con-
sisting of the axle supported in the ends of the drum, this axle has
two or more fingers ¹ fixed to it, and a disc to which is hinged the
rod, provided with a spring acting expansively. The gripper is shewn
closed in Fig. 2, and is supposed to have just caught hold of the edge of
the sheet of paper presented to it, and as soon as the gripper has hold
of the paper the fingers p', which before had been down are raised by the
cam b³. As the drum revolves it presents the surface of the paper
first to receive the powder that drops from the hopper d, then to the
action of the distributor g, then to the action of the rubbing rollers h, i,
j, and k, and then to the cleaning rollers m and n; after passing the
last-named roller the gripper must be opened to release the paper, and
this is effected by the lower notch in the disc coming in contact
with a stud b projecting from one of the frame sides as shewn by dots.
in Fig. 2, and the end of the paper so released is then carried by the
tapes over the pulleys t, the transfer of the paper from the drum to
the tapes being facilitated by the fingers p³ fixed to the under side of
the feeding table. The paper after being carried over the pulleys t drops
edgewise on the fly frame, from which it is transferred to the table v',
with the ornamented side upwards. The pulleys t¹ placed under the
pulleys are covered with india-rubber and hold the paper against the
drum when the gripper has been opened to release the edge. The tapes s
pass over the drum b, pulleys t, and guide pulleys s¹, and act in the
same manner as the tapes of ordinary printing machines, or the
paper or other material may be removed from the drum by other means.
The fly frame v is worked up and down by the cam 67 fixed to the axle
of the drum ; this cam acts on one end of the link u', the other end of
.

page_text: which is jointed to the elbow lever u²; this elbow lever is fixed on the
axle us of the fly frame. The cam 67 raises the fly frame gradually into
the position shewn in dots in Fig. 2, and the fly frame is lowered
quickly by the spring rod u*, which is jointed to the vertical arm of the
elbow lever u³.
As it is of the utmost importance that the rollers by which the
bronzing or other powder is acted upon should be adjusted with great
accuracy, we make the axles of these rollers revolve in eccentric bushes,
one of which is shewn detached in Figs. 4 and 5, the eccentric bush
fits in a corresponding hole in the frame side, and the flange of the
bush is provided with a segmental slot in which is a set screw.
By
moving the eccentric bush partly round the surface of the rubbing or
cleaning roller can be set nearer to or further from the surface of the
paper or other material, and in order to prevent the escape of the powder
into the bearing we recess the bearing, as shewn in Fig. 5, to the
enlarged diameter of the axle. The rollers m and n revolve also in
eccentric bushes, as shewn in Fig. 1, and to the flange of each bush is
fixed a lever, the ends of which are drawn towards each other by an
india-rubber or other spring, by this means the friction pulleys by which
the rollers m and n are driven, are held in contact. The ends of the drum
b, one of which is shewn detached in Fig. 6, are provided with projecting
flanges, taking into annular recesses in the side frames a, the object of
which is to prevent the escape of the bronzing or other powder.
Having thus stated the nature of our Invention and described the
manner of performing the same, we wish to remark that we do not
intend to limit ourselves to the details given, as the number of rubbing
and cleaning rollers, and the position of the same and other parts, may
be varied, and we declare that what we claim is,-
First. The general combination and arrangement of the parts forming
a machine for bronzing or otherwise ornamenting paper and other
materials, as shewn and described.
Secondly. The machinery shewn and described for working the gripper.
Thirdly. The eccentric bushes shewn and described for supporting the
axles of the rubbing and cleaning rollers.
Fourthly. Recessing the bearings of the axles of the rubbing and
cleaning rollers. .

page_text: And lastly, making the ends of the drum with projecting flanges,
fitting into annular recesses in the frame sides, as shewn and described.
In witness whereof; we, the said James Salmon and John Brown-
hill, have hereto set our hands and seals this Ninth day of
January, One thousand eight hundred and seventy-three.
