Improvements in Wrapping Machines.
I, IRA RUSSELL HUTCHINSON, 204, Illinois Street, Chicago, Illinois, 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 :-
This invention relates to certain new and useful improvements in machines for
wrapping caramels in paper, and also for wrapping other articles of merchandise,
such as soap, yeast, etc., etc., and with such object in view my invention consists of
the peculiarities hereinafter fully described and more particularly pointed out in
the several claims.
In the accompanying drawings forming a part of this Specification and on which
like reference letters indicate corresponding parts:

FRAME.
The letter A represents a suitable frame, preferably rectangular and of metal,
O which stands upon legs B and a base C.
PAPER AND PAPER-FEeder.
To the rear beam E of the frame are attached brackets F which carry_a
roller G, on which is wound the endless strip or ribbon of wrapping paper H.

A reciprocating plunger 24 is guided between the ribs 25 on the plate 22, an
adjustable strip 26, pressed by screws 27 being employed to effect the close fit
against the plunger. This plunger is reciprocated by a bell-crank lever 28,
actuated by a cam presently to be described, returned to normal position by a
spring 29, and connected to the plunger by a stud 30 which slides in the bell-crank
lever to compensate for the arc described by the lever. When the plunger
advances toward the wrapper channel it advances the caramel or article under the
detent 32, which insures it against dislocation on account of the jarring of the
machine. As the plunger recedes from under the hopper the caramels or other
articles settle down, and the lower one opposes the plunger. A second movement
of the plunger toward the wrapper-channel advances such caramel or article in
that direction until it meets with the one under the detent 32. When the plunger
returns it leaves the second caramel or article where the first last stood. A third
movement, advances a third caramel against the second, and the second advances
the first upon the flaps p and pl. A second detent 32 depends in the pathway
of the plunger and operates upon the second caramel the same as detent 31 upon
the first caramel.

page_text: and by reason of the contour of the cam 6 the flap remains down until the
plunger makes a second descent, which it then does, incidentally pressing the
Haps firmly down, and pressing the projecting euds of the upper side of the paper
down against the ends of the caramel, to make the product shown in Fig. 8.
This
done, the plunger raises and the double flap t³ descends and folds the paper to
make the product shown in Fig. 9. This flap returning, the double flap
descends, folding the other edges of the paper and making the product shown in
Fig. 10. This done, the latter flap raises and the plunger makes a third descent.
and presses the caramel down into the spout 1, m', a second caramel having in the
meantime, and just before the third descent of the plunger, been projected upon
the supporting-flaps so as to come down with the plunger in its third descent and
act to assist in ejecting the first caramel. This ejection of it forms the product.
shown in Fig. 11, which completes the folding steps or processes. As the caramels.
accumulate in the discharge spout they are forced out. These same operations are
rapidly repeated and the wrapped articles are ejected from the machine as rapidly
as to amount almost to a stream, as ascertained in the practical operation of this.
machine, which has been exhaustively tested.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. In a wrapping machine, the following instrumentalities: The wrapping
channel, supporting flaps across said channel, wrapping mechanism consisting
essentially of a plunger and a double set of flaps, one set being above the other,
article feeding mechanism consisting of a hopper, and a reciprocating plunger
traveling across the bottom of the hopper and adapted to feed the articles upon
the supporting flaps, and suitable devices to prevent the return of the articles when
the plunger moves back.
2nd. In a wrapping machine, the following instrumentalities: A wrapping
channel, supporting flaps across the channel, wrapping mechanism consisting
essentially of a recessed plunger and a double set of flaps, one set being above the
other, article feeding mechanism consisting of a hopper and a reciprocating plunger
traveling across the bottom of the hopper and adapted to feed the articles upon
the supporting flaps, and one or more detents to engage with the articles to prevent
their dislodgement.
3rd. In a wrapping machine, the combination with a wrapping channel, of two
associated flaps mounted at the opposite sides of the said channel, respectively, and
operating mechanism for said flaps arranged and combined with one flap to turn it
down to fold over one edge of the paper about the article and then to turn the flap
back, and with the other flap to turn it down to fold the other edge of the paper
over the article and to delay this flap in a down position, and a reciprocating
notched plunger which descends and folds the upper projections of the paper down
against the ends of the article then ascends, after which the delayed flap through
its mechanism is turned up.
4th. In a wrapping machine, the combination with a wrapping channel, a plunger
provided with a central recess, two upper folding flaps and two double lower folding
flaps, all operating within said channel, of a series of cams and intermediate
mechanism whereby the plunger is given one descent, one of the upper flaps is
turned down and back, the other upper flap is turned down and held, the plunger
is given a second descent, such delayed flap is turned back, one of the double lower
flaps is turned down and back, and the other is turned down and back.
5th. In a wrapping machine, the combination with a wrapping channel, of
an upper set of flaps and a lower set of double flaps, the flaps of each set being
arranged upon the opposite sides of the said channel, and mechanism for operating
the said flaps so that one flap of the upper set shall turn down and back, and the
other turn down and be delayed and then turned back after such delay, one of the
lower set shall turn down and back and then the other shall turn down and back,

page_text: and a recessed plunger, and mechanien to operate it to cause it to descend and
ascend prior to the movement of the first of the upper flaps, and then make a
second descent and ascent after the second flap has been turned down.
6th. In a wrapping machine, the combination with a wrapping channel, a
recessed plunger for making the first end folds, working within the channel, yielding
supporting flaps standing normally across the channel, a feeding plunger operating
to feed the articles upon said supporting flaps and then withdraw, and two sets of
folding flaps, the upper set consisting of two flaps and the lower set of two double
flaps, one set being above the other set, and mechanism for operating the wrapping
plunger, the feeding plunger, and both sets of flaps at the proper time, substantially
as described.
