"IMPROVEMENTS IN APPARATUS FOR SUPPLYING GUM, GLUE, PASTE, COLORS, OR
VARNISH TO PAPER, VENEERS, SHEET METALS, WOVEN OR FELTED FABRICS, OR
FOR DAMPING THE SAME."
This Invention relates to improved apparatus for supplying gum, glue, paste, or
colors to the surface or surfaces of paper, veneers, sheet metals, woven fabrics, or
other surfaces requiring to be coated as aforesaid.
A machine constructed according to this my Invention comprises a roller partly
immersed and free to remove in gum, glue, or colouring matter contained in a
trough, and supplied from a reservoir having an air tight cap or stopper, and
provided with a sluice or valve controlled and adjusted by regulating and holding
screws, so as to regulate the supply to the trough; the pasting or coloring roller is
rasped or spiked around its diameter for purpose of drawing the paper or material
through or between the upper surface of the roller and a cover or cap thereon, and
the latter is by springs pressure adjusted that the degree of tension on the material
drawn through the machine in regulated. There is a guide plate for facilitating
the leading in to the machine, and on the other side of the roller is a delivery plate
having ribs and a recess, the ribs or ridges serve to guide the paper to its delivery
point, and avoids removal of the gum, glue, or color, and the recess affords free
access to the attendant on the machine to grip or lay hold of the paper or material
on its emerging when it is drawn through, and its frictional contact with the gum or

supplied to the roller, and ensure any superfluity being returned to the trough. The
reservoir and trough and machine containing the liquid are hinged or mounted so
as to be capable of being tilted, and returning the gum or color to the reservoir
and the sluice valve or stop tap put down or turned, securing the liquid in the
reservoir.
Such being the nature and object of this my said Invention I will now procced
to describe the particulars thereof, and in order that the Invention may be fully
understood I have hereunto annexed 3 Sheets of Drawings.
DESCRIPTION OF THE DRAWINGS.

page_text: trough and cistern; at Fig. 13 is shewn application of drying cylinder in connection
with the machine; Fig. 14 is a sectional elevation; Figs. 15 and 16 are elevation
and end view of scraper and presser roller; Figs. 17 and 18 are plan and section
of tension cover and gripper roller; Fig. 19 is elevation of roller, straight edge,
and guide for supplying gum at intervals of width of sheet (column gumming), and
the support for the paper; Fig. 20 shews form of scraper for this roller.
At i is a roller of brass or other suitable material, by preference spiked or
roughed, as at 1°, to ensure grip or bite on the paper. The said roller is mounted
and free to revolve on bearings 2 upon its studs or axles, over which roller is a
pressure or tension plate 3; the under surface thereof is about the same radius as
the diameter of the roller 1. At 4 is a vessel containing gum, water, paste, or
coloring matter, on the top of which is an air tight cap 5. The lower part of the
vessel 4 communicates with the trough 6, and supplies a uniform height or quantity
of gum or other liquid to the said trough. At 7 is a table or guide plate on which
the leading end of the paper or other material to be gummed, pasted, or otherwise
covered is placed, and passed to the upper part of the roller and of the tension
plate 3 (or an upper roller may be employed in lieu of the plate 3). The end of
the material soon as it protrudes on the other side of the roller and guide plate at
8 is seized by the attendant on the machine and pulled through, its surface being
coated with the adhesive or other liquid, and passes over the ridged delivery table
or platform 9 clear of the machine. The ridges 9 serve to guide the end of the
paper or other material in its exit, and prevents its end passing down to the
trough, and also does not rub off or remove the liquid as an even or flat surface
table would, and also prevent adhesion of the material to the exit platform 9. At
10, 10, are two hinged springs, which are free to turn on centre pins 11. These
springs, when upon the ridges of the cover plate 3 (see Figs. 3 & 4), exert pressure
upon the said cover, and so regulate the tension on the material being drawn
through the machine. At 12 is a rake or blade mounted in bearings 13, and
movable by means of the arm 14 that its edge may be so adjusted in relation to
the roller 1 as to determine what quantity of liquid the roller 1 shall take up,
and remove any superfluity therefrom, which will run down into the trough again.
The under side of the rake or blade is divided in hollows at the bottom, so as to
prevent the secretion of liquid between the blade and the trough after the machine
has been tilted (as hereinafter described). The arm 14 is secured in position to
which it has been placed by means of the slotted springs 15. At 16 is a slit or
slot which serves to receive the lugs on the cover 3. The trough 6 and vessel 4
may be hinged, as shewn at 17, so that on the whole being tilted the liquid will
run from the trough to the vessel 4 again, in which it is secured by means of the
screw valve 18 held to its seating or face of the aperture in the vessel 4 by means
of spring 19. The spindie 20 is jointed to the valve at 21. The joint facilitates
removal of the valve from its seat or facing, and for cleaning or other purposes.
At 22 is a guide nut or screw, through which the spindle 20 is passed, and on
which nut is a locking finger 25 which enters groove 24 formed in the cap 5, so
as to prevent the removal of the cap without first unlocking the cap. The screw 26
is for the purpose of raising and setting the valve 18.
Referring now to the machine designed for execution of large quantity of work,
and driven by gear, fly wheel, or pulley (or treadle), illustrated on Sheet No. 2.
At 27 is an elastic platform supported on pillars or spindles 28 having spiral
springs 29 thereon, which springs serve or tend to force the platform upwards to
the feed roller 30. This platform is further adjustable to roller 30 by means of
the screws 31, 32; at 33 are a number of sheets or labels to be gummed, 34 & 35
are draw rollers (draw filed or roughed on their periphery for the better gripping
the paper), these rollers draw and propel the sheets through the machine as
successively passed or fed thereto by the feed roller 30; at 36 is a gumming roller
partly immersed in gum contained in trough 37; at 38 is a strickle which removes
superfluous gum from the roller 36, the upper portion of the strickle 38 serves to

page_text: shield the draw rollers 34, 35, from contact with the gum, the strickle 38 is carried
at each end by bearings; 39, 40, is a tension cover, its edge 41 bears on the paper,
the roller 34 being carried by brackets attached to this cover; at 42 is a straight-
edge or scraper, see Figs. 11, 15, and 16, between the upper edge of which and the
roller 43 the paper is passed; this straightedge or scraper and the pressure roller
serve to level and smooth the gum and to determine the thickness of layer.
The
roller 43 is adjustable on its axis 44 in relation to the straightedge 42 by means of
the screws 45 on tension cover 40, that is to say, as the screws 45 are raised or
lowered so will the roller 43 be nearer to or further from the edge or angle of the
straightedge 42, thus determining to what degree the straightedge shall bear upon
the gummed surface of the paper, whilst the teeth like projections thereon form an
inclined guide and platform affording small surface contact between paper and
platform, and the spaces or openings between the teeth act as return passage ways
for the gum scraped off the papers or labels; 45ª is a gauge or guide for the
papers on their passage to the feed rollers.
The machine is geared and driven as follows:-At 40 is a hand wheel or driving
pulley mounted on the axis of the gumming roller 36; on the same axis is a spur
wheel 47 gearing with an intermediate stud wheel 48, the latter driving pinion 49
on axis of draw roller 35 and also stud wheel 50, the latter driving wheel 51 on
axis of feed roller 30; 53 is a catch in gear with wheel 48 for preventing the
machine being turned the wrong way. On the gum cistern 52 is a tap 54 for the
admission of air when the gum, by tilting the machine, is being returned to
the vessel 55, the interior of which has a divisional inclined plate, as shewn by
dotted lines, which facilitates the clearing of the trough 37.
Where sheets are to be gummed at intervals (column gumming) or along their
edges, such as book post wrappers, envelopes, and the like, the roller 36 is removed
and replaced by roller 56, shewn at Figs. 19, 20, the collars 57 are adjustable on
the spindle 58 and may be of any number or width according to the work required;
in connection with this roller is the scraper, of form shewn at Figs. 19 & 20, that
is to say, having supporting parts 59 for holding up the paper within the spaces
between the collars or of the end of one collar as the case may be.
At 60, Fig. 13, is the drying cylinder over which the papers as gummed are
drawn in the direction shewn by arrows, or the drying apparatus may consist of
endless sheet running through a hot chamber.
When gummed papers require large quantity of gum the cover 61, Fig. 14, is
substituted for the tension cover 40 of Fig. 11.
At 62 is a sluice valve employed for trapping or preventing the return of the
gum from the vessel 55 when the machine is not in use. At 63 are shewn screw
and nut for raising and lowering the said valve.
At 64 is a spring which keeps the sluice close up to the face of the seat of the
valve.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be or may be performed or
carried into practical effect, I would have it understood that what I claim as my
Invention is,-
Firstly. The construction and use in combination of the scraper 12, tension
plate 3, delivery table or platform 9, in manner herein described, and substantially
as shewn by Drawings.
Secondly. The combination of vessel 4 having an air tight cap 5 (screw sluice
valve 18, and trough 6, as herein described and illustrated by Drawings.
Thirdly. The construction and use in combination of the spring platform 27,
feed roller 30, and tension cover 40, as illustrated by Drawings (Sheet 2), and as
herein described.
Fourthly. The combination of the gripper rollers 34, 35, roller 36, and tension
cover 40, as described and illustrated by Drawings annexed.
Fifthly. The straightedge or scraper 42 in combination with the roller 43 (or

page_text: in combination with a fixed bar, the equivalent of 43), in manner herein described
and illustrated by Drawings.
In witness whereof, I, the said John James Allen, have hereunto set my
hand and seal, this Tenth day of November, in the Year of our Lord One
thousand eight hundred and eighty one.
