PROVISIONAL SPECIFICATION.
Apparatus for Making Paper Cases for Enclosing Cigarettes or other
Articles.
We, RICHARD DALTON of No. 2 Carnarvon Road, Redland, Bristol of the City and
County of Bristol, Commercial Traveller and HENRY HERBERT WILLS of the firm of
W. D. & H. O. Wills of the City and County of Bristol, Tobacco Manufacturers do
hereby declare the nature of this invention to be as follows:
:--
The object of my invention is to provide a simple machine which will rapidly
and efficiently manufacture cases for enclosing cigarettes or other articles.
According to my invention I carry on an endless band plates or blocks to suit the
size of the interior of the case to be made. This band travels in proximity to a
feeding device by which the paper blanks are fed either by hand in separate pieces or
from a roll or continuous supply cut into proper lengths by a cutter provided on
the machine. The inner end of each blank is received between the plate and the
band, its proper position being ensured by a stop. As the band moves round each
blank is folded over the block by coming against a guide or folder in proximity
thereto. By the further movement of the band the blanks are passed between other
folders which fold down the side portions there being in proximity to these latter
folders a pasting or cementing device by which paste or cement is applied to the
folded edges.
As the cases thus formed and cemented are carried still further
they pass between surfaces or spring rollers preferably heated, so that the edges are
held in place till the cement is dried sufficiently to enable the cases to retain their
form. On the still further movement of the band the formed cases on their blocks are
acted upon by takers-off preferably consisting of discs or rollers rotating at a higher
speed than that at which the band travels, so that they grip the case and remove it
from the block, which block then travels forward to receive another blank and
so on. The band may have any convenient number of these blocks upon it.

We RICHARD DALTON of No. 2 Carnarvon Road, Redland, of the City and County
of Bristol, Commercial Traveller and HENRY HERBERT WILLS of the firm of W. D.
and H. O. Wills of the City and County of Bristol Tobacco Manufacturers 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 :-
The object of this invention is to provide a simple machine which will rapidly and

are fed either by land in separate pieces or from a roll or continuous supply cut into
proper lengths by a cutter provided on the machine so that the inner end of each
blank is situated between one of the said plates or blocks and the band, the proper
position of the blank being ensured by a stop. As the band moves round, each blank
is folded over its block by coming against a guide or folder in proximity thereto.
By the further movement of the band the blanks and blocks are passed between other

page_text: folders which fold down the side portions, there being in proximity to these latter
folders a pasting or cementing device by which paste or cement is applied to the
folded edges.
As the cases thus formed and cemented are carried upon their blocks
still further they pass between bands spring rollers or equivalent devices (preferably
heated) so that the edges are held in place till the cement is dried sufficiently to
enable the cases to retain their form. On the still further movement of the band
the formed cases are removed from their blocks which may be done by hand or
by mechanical takers-off preferably consisting of discs or rollers rotating at a higher
speed than that at which the band travels so that they remove the case from the block,
which block then travels forward to receive another blank and so on.
The band may
carry any convenient number of these blocks.
And in order that the said invention may be fully understood we now proceed to
describe the best means with which we are acquainted of carrying the same into
practical effect and for that purpose shall refer to the several figures on the
annexed sheets of drawings the same letters of reference indicating corresponding
parts in all the figures.
Figure 1 is a side sectional elevation and Figure 2 is a plan of an apparatus con-
structed according to this invention and Figures 3, 4, 5 and 6 are sections taken
respectively along the lines 1-2, 3-4, 5-6 and 7-8, Figure 1, these sectional
views being drawn to a larger scale to more clearly illustrate the mechanism for folding
and connecting the sides of the cases.
دو
A is the main frame of the apparatus carrying in bearings B the main driving
shaft C which may be driven from any suitable prime mover by a strap passing round
the pulley D. On the shaft ( is a pinion E gearing with a spur wheel F on a stud G
and transmitting motion through a spur wheel G2 to a shaft H. On the shaft H is
mounted a drum or pulley H2 having a groove in its periphery for the reception of an
endless steel band I the said band also passing round a similar drum or pulley H³ on a
shaft G3 at the opposite end of the apparatus. At suitable intervals along this endless
band I are loosely connected plates K upon which the paper cases are formed. The paper
blanks (one of which is shewn in Fig. 1") to form the cases are fed singly by hand or
otherwise into a hopper L which conducts the blanks into position between the plates or
formers K and the endless band as shewn at M Figure 1, each blank as the band
travels round the drum H³ being held between the said band and the "formers with
a portion projecting in front of the "former" sufficiently long to form one side and
the bottom of the case. As the blank held by the
" former moves forward, the end
of the overhanging portion of the blank is raised which may be done by causing it
to rest on a projection from the band just in advance of the forward edge of the
block but preferably by projections on the underside of the band I acting on
levers N so as to cause the end of the overhanging portion of the blank to be raised above
a stationary rod or bar P as shewn by dotted lines in Figure 1 so that as the "former"
passes beneath the said bar or rod the projecting portion of the blank is folded
along the line 1-2 Fig. 1" onto the top of the "former." The former" with the
blank thus folded thereonto passes thence beneath a roller Q which holds the blank
securely on the " former while projections a from opposite sides of a trough or
passage S through which the "former" next passes, press inwards the projecting
portions 3 of the blank, on the front or advancing end of the " former," to form the
corners of the bottom of the case.
"
"
"
"
At the mouth or entrance to the trough or passage S are inclines R as shewn in
Figure 3 which as the "former with the blank thereon advances turn up the pro-
jecting edges 4 of that portion of the blank which is situated between the former
and the band I. The overhanging edges 5 of the top portion of the blank are then
pasted by coming into contact with discs T (shewn in Figure 4) rotating in a
trough V containing paste or other suitable cement or adhesive material. These discs
receive motion from the main shaft C through the pulley U and driving band U²
and as they revolve in the paste or the like they are continually coated with a filo
thereof which they transfer to the under surface of the overhanging edges 5 of
the upper portion of the blank as they move in contact therewith. The former "

with the partly formed case thereon moving forward, the projecting pasted edges of
the upper portion of the blank are turned down or folded over the turned up edges 4
of the lower portion of the said blank, by inclined surfaces W formed on a piece
or cover X (see Figure 5) of the passage or trough S. This trough or passage is
heated from below by means of a gas burner Y as shewn, or by any other convenient
means so that as the "formers" with the cases thereon pass through this passage
the paste by which the parts are connected are thoroughly dried, and to ensure
the pasted parts being held in contact while passing through the trough or passage,
endless bands Z are arranged to travel edgewise on opposite sides of the trough and
are pressed against the sides of the cases on the formers by plungers acted
on by springs as shewn in Figure 6. The bands Z are carried on pulleys c c²
which are driven by a gut or band d passing round pulleys e on the frame A and
pulleys connected with the pulleys c². To prevent adhesion in case of any paste
or gum having escaped to the surface of the bands Z it is preferred to drive the
said bands at a speed slightly different from that at which the cases and blocks
are travelling. The "formers" with the cases thereon as they pass from the trough
or passage S pass round the drum H2 and enter thence between two discs
on a shaft h. These discs are faced with or have attached to their inner sides,
surfaces of india rubber or equivalent material against which the edges of the cases
are caused to bear when passing between them and as these discs are caused to
travel or rotate at a considerably greater speed than the band I they drag the
cases off the "formers' as they pass between them and deposit them into a
receptacle placed in position below to receive them a stationary spring blade / being
arranged between the discs to detach the cases therefrom. Fig. 1b shews in per-
spective a finished case. The discs g may be driven at the required speed from any
suitable part of the machine or from any other available source; in the drawing they
are shewn as being driven from the shaft H by a gut or band i passing round a
pulley k on the said shaft and round a cone pulley k² on the shaft carrying the discs.
m are scrapers for removing any paste that may get onto the bands Z. n is a grooved
roller situated between the discs g to guide the band I between the said discs to ensure
the cases being removed from the "formers."
