Sheets of Paper and other Materials.
I OREL DIGHTON ORVIS of St George's Club, Hanover Square in the County of
Middlesex, Engineer, 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 chief object of this invention is to produce a simple and effective apparatus for
applying a solution of glue or other adhesive substance to the sheets of paper used in
the manufacture of paper boxes, but the invention is also applicable to applying these
substances to paper and other material generally.
In the accompanying drawings I have shewn at Fig. 1 a side elevation of my
improved apparatus. Fig. 2 is a plan view of the same, and Fig. 3 is a right hand
end view.
A is a frame of any suitable construction supporting a platform or table B, and the
gumming or pasting mechanism. C is an endless band to receive the gummed paper
as it issues from the gumming apparatus, and carry it forward within reach of the
workers, who sit on either side of a table D, above which the band C is arranged
to work.
The table or platform B, which may be of any suitable length and width, I prefer
to form with a semicircular recess in which the attendant (usually a female) may sit,
so as to be within convenient reach of the gumming apparatus. The sheets, pieces,
or lengths of paper or other material of the several colours required for, say, one form
of box, will be piled up on the sides of the table, the attendant's duty being to watch
the workers and feed into the gumming machine such pieces of the paper as may be
at the moment required. In some cases, several forms of boxes may be in course of
manufacture at one time, which may require many different colored papers, and I
then provide a supplementary table or tables, which will be arranged and secured
above the table B in any convenient manner.
The gumming or pasting apparatus consists of a pair of feed rollers a
mounted in bearings in side plates E firmly secured to the frame A.
a,
which are
These side

page_text: plates E also serve to carry other rollers and paris of the gumming apparatus. In
rear of the rollers a a is a funnel shaped guide b, which supports the paper between
the feed rollers and the gumming or mucilage roller.-e is the mucilage roller, which
I prefer to form of iron covered with brass, and turn down perfectly true. Imme-
diately below the roller c, and longitudinally of the same, is arranged a perforated
pipe d, to which air is conveyed by the vertical pipe d' from any suitable blowing
apparatus.
The object of this air blast is to press the paper or other material up against the
mucilage roller c. By the side of, and in close proximity to the roller c, is mounted
a rod or bar e, on which are strung and fixed by clamping screws, a series of stripper
fingers the points of which rest in contact with the roller e, and serve to strip off the
paper which has been coated with adhesive material, and guide it onto the endless
and C, which passes round a roller y arranged in close proximity to, but below the
roller Cz and is driven therefrom. As the air blast is likely to cause the front edge of
the paper to curl up and prevent its lying flat on the band C, thereby rendering the
paper liable to buckle, and interfering with its forward motion, I provide a pin
roller h, which will seize the edge of the paper, and hold it down onto the band against
the action of the blast.-A second set of stripper fingers will be arranged and
clamped upon a second rod or bar el in rear of the pin roller, to strip the paper off
the pins, and the paper will then move forward, lying flat on the band, and unaffected
by the air blast.
The endless band C passes round a second roller g at the opposite end of the
table D, and suitably carried in a rocking support, to which a suitable tension
apparatus, as g, is applied, in order to give the requisite amount of tension to
the band.
Motion is communicated to the roller through a pulley mounted on the axle
thereof, from any prime mover, and from the roller c to the other moving parts, by
suitable gearing (in the drawing, band pulleys are shown), care being taken that all
the moving parts shall have the same surface speed.
The adhesive material is contained in a fountain or trough i carried by the side
plates E, or in any other convenient manner. The bottom of this trough may be
made moveable by means of adjusting screws, for the purpose of regulating the flow
of the material therefrom onto the roller c, according to requirements. I may, how-
ever, remark that I do not intend to confine myself to any particular form of fountain,
as any well known and suitable fountain arrangement may be employed.
Under ordinary circumstances, the air blast will be cold, but I may, for some
purposes, use a hot blast, which will have the effect of hastening the drying of the
adhesive material. The heating of the air may be effected in any suitable manner,
but it forms no part of my present invention.
Means will be provided within reach of the attendant at the table B, for shifting the
driving belt onto a loose pulley mounted on the axle of the roller c, so as to stop the
apparatus as desired, and also to shut off the air blast.
In some cases, it may be desirable to collect, and more or less compress the air in
a suitable vessel, in which case the vessel may be carried by the frame A. I may,
however, remark that this forms no part of my invention, and is not necesssary to
ensure the proper working of the apparatus above described.
In place of the endless band, I may in some cases substitute a roller, which, in
combination with the pin roller, will forward the gummed sheet of paper onto a table,
or even onto an endless band.
I use the air blast to keep the paper up to, and in contact with the mucilage roller c,
in preference to a pressure roller, as being more simple; for unless mounted in a
rocking frame, whereby it could be raised and lowered as required, the pressure roller
would be running in contact with the mucilage roller, and so apply the adhesive
material on both sides of the paper.
The object of the funnel guide is to catch any adhesive material dropping from
the fountain, and to convey the paper well up to the mucilage roller before it can be

page_text: acted upon by the blast, the tendency of which will thus be to blow the paper up to
and onto the roller c.
By the use of my improved apparatus, the gumming operation will be effected more
efficiently and evenly than by hand, and in less time, while all waste will be avoided,
as the adhesive material will be applied only as and when the paper is required.
Several different kinds and forms of boxes can also be manufactured at one time,
without any other change in the apparatus than an additional table or shelf on which
to place the different sorts of papers.
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 :-
--
1st. An apparatus for applying an adhesive substance to the surface of paper or
other materials, constructed, arranged and operating substantially as herein shown and
described.
2nd. In apparatus for applying adhesive substance to paper and other materials,
the use of an air blast for pressing the paper against the surface of a roller charged

combination with a mucilage roller, and means for pressing the paper against said
roller, of stripper fingers as and for the purpose set forth.
4th. An apparatus for applying adhesive substance to paper and other materials,

means for stripping the paper off said roller, of the pin roller, a second set of
stripper fingers, and an endless band or equivalent forwarding mechanism as hercin
described.
5th. In apparatus for applying adhesive substance to paper and other materials, the
combination with a mucilage roller, and means for pressing the paper against said
