I, WALTER HAMILTON COE, of 166, Cranston Street, Providence, Rhode Island,
United States of America, 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:-
My invention relates to a machine for winding decorative films of metallic leaf in
connection with an accompanying strip of paper or other suitable material to form a
package roll, from which the metallic film is to be subsequently' unwound and
deposited upon the surface to be decorated, and it consists in the combination of
means for drawing the strip forward, with a pressing roller, a table for holding the
book of metallic films, and means for automatically causing the lapping contact of
the metallic films upon the strip.
It also consists in the combination of means for winding up the strip and film
into a package roll, with a bar of wax or other suitable material in contact with
which the strip is drawn to receive a coating adapted to secure the proper adhesion
of the film to the strip, and means for applying the film to the strip.
It also consists in the combination of means for drawing the strip forward, with a
pad for spreading crocus or other powder upon one side of the strip to prevent the
adhesion to the film thereto, and a bar of wax or other suitable material in. contact
with which the strip is drawn to receive a coating upon the opposite side of the
strip to secure the proper adhesion of the metallic film.
It also consists in the combination of a pressing roller, a table for supporting the
book of metallic films, and means for automatically lapping the films upon the strip,
with a roller held in stationary bearings and a roller held in movable bearings
adapted to hold the winding package in contact with the pressing roller.

In the accompanying drawings, A. represents the frame of the machine, the said"
frame being provided with the front legs aa and the rear legs a¹ a¹, which are;
secured to the bench B by means of the screws b.., The upper end of the frame A
is provided at its opposite sides with the open journal-bearings c, adapted to
receive the journals of the mandrel C, upon which is placed the paper-strip-
supply roll D, from which the paper strip is to be drawn in the operation of the
machine.
J
:
The front and rear portions of the frame A are connected by means of a rod d, 3
to which are pivoted the arms dd, which at their outer ends are rigidly connected
by means of the rod d², and loosely upon the rod d² is placed the cylindrical
receptacle for the crocus or other powder employed for providing the paper
strip with a surface non-adhesive to the film, the said cylindrical receptacle being.
provided with the central tube d³, arranged loosely upon the rod daud provided, 4
with the longitudinal wings d d. The periphery of the said receptacle is formed
of wire cloth or other foraminous material, through which the desired quantity of
powder may be made to pass upon the revolution of the said receptacle upon the
rod d².
..I
The narrow rubber band d, which is placed over the periphery of the powder- 4
receptacle E, serves by frictional contact with the periphery of the supply-roll D
to cause the proper revolution of the powder-receptacle E and the sprinkling of
the powder in suitable quantity upon the surface of the paper strip G, the wings d
serving to maintain the proper loose condition of the powder in the powder-
receptacle during the rotation of the same with the receptacle E. At the opposite 5
corners, of the upper portion of the frame A are pivoted the arms e e, which are
also pivoted to the opposite ends of the block F, preferably hollowed upon its
bearing-surface and provided with the attached woolen flap e, which serves to
properly distribute the powder previously sprinkled upon the surface of the paper
strip from the powder-receptacle E. The properly prepared and powdered paper 5
strip: G passes from the supply-roll D under the tie-rod f of the frame, thence over-
the pad H, by means of which any surplus of the powdering material-may be

page_text: removed to fall into a suitable receptacle, thence over the tie-rod ff and downward
to contact with the inner side of the cylindrical bar of wax I, the said bar of wax
being arranged at the side of the paper strip opposite to the powdered surface and
held upon a stationary rod, to the opposite ends of which are attached: the
arms 9 g, which arms are connected to each other by means of the rod and are
pivoted to the tie-rod f of the frame. The bar of wax I is made adjustable to
expose a greater or less surface of wax to the paper strip by means of the screw g²;
pivoted to the arm gl and passing loosely through a perforation in the inwardly-
extending ear g³ of the frame and provided with the milled nut gt, by means of
which the desired adjustment is effected. The oppositely powdered and waxed
paper strip thence passes to the periphery of the pressing-roller J, the powdered
surface of the paper strip being on the inner side in contact with the roller and
the waxed surface h¹ of the same being upon the outer side.
The pressing roller. J is secured upon a shaft i by means of the set-screw, held
in a hub at the forward end of the roller, the opposite end of the shaft i passing
through the loose sleeve 22, upon the outer end of which is secured the gear 13,
which engages with the teeth of the rack it, by means of which the gear 3 may be
actuated in opposite directions, the said rack it being jointed to the arm 25, which
is secured to the loosely-journaled bar 20, provided with the outwardly-extending
hand-lever K, by means of which the machine is operated, the said hand-lever.
being held in its upward position by means of the spiral spring 17, securel at its
upper end to the under side of the bench B. To the inner end of the sleeve i², at
the inner side of the frame A, is secured the gear 28, which engages with the rack-
teeth of the sliding bed L, the said sliding bed being supported between the
parallel sides of the frame A upon the parallel ways ¹. The downward and
upward movement of the haud-lever K by the operator of the machine will cause a
rocking, movement of the sleeve 2 and the gear and a corresponding reciprocating
movement of the sliding-bed L.
The sliding bed L carries the table M upon which the book of prepared
decorative films is to be placed in proper position for the attachment of the films
singly and properly lapping each other upon the waxed side of the paper strip, the
said table M being provided with the downwardly extending lugs 22, to which are
pivoted the bell-crank levers j³, which levers are loosely held upon the stationary
bearing-rods jo, held in the downwardly-extending lugs 777 of the sliding bed L.
The said bell-crank levers are connected with each other, so as to move in
unison, by means of the connecting-link 8, to the rearward side of which is secured
the spiral spring, (shown in Figs. 11 and 12,) the opposite end of the said spiral
spring being secured to the loose bell-crank lever k, which is held together
with the loose bell-crank lever ³, upon the stationary bearing rod j. At the rear-
ward side of the forwardly-projecting horizontal arm of the bell-crank lever k is
secured the stud k, which engages with the upper surface of the latch-cam k*, the
said latch-cam being pivoted to the inner side of the frame at the point 95 and held
by a suitable stop in its normal position, as shown in Figs. 5 and 6, and adapted to
be raised at its outer end upon the engagement of the stud with the incline k² at
the backward movement of the sliding bed L. The pressing-roller J is operated
intermittently by means of the ratchet-wheel n, which is secured to the rearward
end of the said pressing-roller and the spring-actuated ratchet-catch n¹, the
notches 2 of the ratchet-wheel being so arranged that upon the downward
movement of the hand-lever K by the operator of the machine the pressing-roller J
will be turned so that the periphery of the said roller will be moved forward for a
space equal to the length of one of the sheets of decorative film less the distance
required for the lapping contact of the edges of the said sheets upon the paper
strip G.:
When the operator of the machine depresses the hand-lever K, the sliding bed L
and the table M will be carried forward under the pressing-roller J until the stud k¹
engages with the. incline at the outer end of the latch-cam k, thus causing the
said stud to rise to the top of the said latch-cam, thereby causing the angular

page_text: movement of the bell-crank lever k, which through the spiral spring, connected
with the link j, serves to lift the book of films held upon the table M to contact
with the paper strip. G at the under side of the pressing-roller J. At the back of
the pressing-roller J and at a certain distance therefrom is placed the stationary
roller N, provided at its forward end with a gear m; which is connected with the
gear m¹ upon the forward end of the pressing-roller J by means of the intermediate
gear m². The movable roller N¹ is journaled in the opposite arms m³ m, which are
rigidly secured to the rod m³, the said rod being loosely journaled in the sides of
the frame A, so that the roller N¹ may have an up-and-down novement in the arc of
a circle whose center is in the axis of the rod m5. To the outer end of the arm m
is attached the cord mo, which passes over the pulley m', and to the pendent end of
the cord m is attached. the weight m³, by means of which a portion of the weight
of the movable roller N¹ may be balanced, so as to secure the required degree of
pressure upon the package-roll O, which is held for winding revolution between
the said roller N¹, the stationary roller N, and the pressing-roller J. The peripheries
of the rollers N and N¹ are preferably made to move at a slightly greater rate of
speed than that of the periphery of the pressing-roller J in order to wind the
package-roll O tightly. The movable roller N is provided at its forward end with
the gear mo which is connected with the gear m¹ upon the forward end of the
pressing-roller J by means of the intermediate gear me, held upon the rod m³, which
forms the pivoting-point of the movable roller..
The forward end of the shaft i is provided with the eccentric-pin m³, which
extends outwardly into the slot n of the ratchet-lever n5, the said ratchet-lever
being pivoted upon the stud no, secured to the frame A and carrying at its outer
end the spring-actuated ratchet-catch 7, which engages with the teeth of the
ratchet-wheel n³, turning loosely upon the stud n6; and upon the outer side of
the ratchet-wheel is secured the cam no, which serves to actuate the hammer o of the
bell P, the said ratchet-wheel being prevented from retrograde movement by means
of the gravitating pawl o', and 'the ringing of the bell P will serve to give notice to
the operator of the proper filling of the package-roll O. At the rear of the machine
is placed the mirror Q, which may be set at the proper angle to reflect the under side
of the strip and film to the eye of the operator, so that upon the occurrence of any
imperfection in the attachment of the film to the surface of the paper strip G the.
operator of the machine, may readily detect the same and make suitable correction
thereto without being obliged to stoop and look under the strip and film at each
operation of the machine, aud the application of the said reflecting-mirror to the
machine for the necessary inspection of the condition of the film, whereby a great
saving in time is effected, constitutes an important feature of the invention.
at
In the operation of the machine, the book of films, such as now in use for
holding metallic films for gilding and decorating, is to be clamped upon the
table M so that the back of the said book will rest upon the table at about the
line in Fig. 4, the backwardly-thrown opened leaves of the said book being
suitably clamped to the table by means of the spring-button s, which is pivoted
upon the screw 8¹, so as to be moved to the required position. Then as the
hand-lever K is depressed by the operator the sliding bed L will be carried forward:
under the pressing-roller J, so that the stud k will engage with the incline
the outer end. of the latch-cam k, thus causing the upward movement of the
table, with the attached book of films, until the top film.of the book strikes against
the previously waxed under surface of the paper strip G, the said book of films
being then held against the said paper strip on the pressing-roller J, with a yielding
pressure, the said yielding pressure being caused by the resilience of the spring ;
which serves to maintain the table M in its elevated position under the pressing-
roller. The said top film of the book of films will be carried forward in contact
with the paper strip and pressed thereon until the stud arrives at the pivoted
end of the latch-cam and drops therefrom, thus releasing the table M and
allowing it to drop to its former position upon the sliding bed L, the rapidity.
of the downward movement of the said table, being checked by means of the

page_text: spiral spring 5, which is attached at one end to the connecting link j8 and at the
other end to the downwardly-extending pin ke, which is secured to the underside
of the sliding bed, the said spring thus serving to prevent the rattling noise
which would be otherwise caused by the falling movement of the table M. As
soon as the table M has dropped to the supporting-surface of the sliding bed L,
the upward movement of the hand-lever K will cause the backward movement of
the sliding bed L and the table M, the stud passing back under the latch-cam k*,
which latch-cam will be lifted by the stud; and then fall to its normal position
after the passage of the said stud beyond the outer end of the said latch-cam, so
that upon the return movement of the said stud it will again be raised by the
incline at the outer end of the latch-cam. While the table is in its extreme
backward position, as shown in Figs. 2 and 4, the operator turns another leaf of
the book of films, thus exposing a new film, which will be properly applied to the
paper strip G and lapped with the edge of the previously-applied film upon the
succeeding depression of the hand-lever K, by means of which the exposed film
will be first brought to the required point and then raised to contact with the paper
strip, as before, with its forward edge lapped to the proper extent upon the
rearward edge of the previously-applied film, and this operation will be continued
until all the leaves of the said book of films have been turned and the exposed
films attached to the under side of the paper strip G upon the pressing-roller J.
The said lapped and attached films and the paper strip are wound into a
package-roll O upon the core v, which is preferably made of wood or other similar
light material, and while the machine is being operated as above described the
paper strip G is being supplied with the crocus or other powder upon one of its
sides and with the wax or other adhesive material upon the other, preparatory
to the attachment of the films, and upon the attachment of the proper number of
sheets of film upon the paper strip G the automatic ringing of the bell P will
notify the operator that the package-roll has been properly completed and requires
removal from the machine, which removal may be readily effected by raising the
movable roller N¹.
When an imperfection in the laying of the film upon the paper strip G is shown
by means of the reflection in the mirror Q, the said imperfection may be readily
repaired by the operator before it enters the package-roll O, and by means of the
mirror the condition of each successively-attached sheet of film upon the paper
strip at the under side of the pressing-roller J can be readily determined without
obliging the operator to look under the pressing-roller at each operation of the
machine.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
