COMPLETE SPECIFICATION.
Improvements in Machines for Applying a Coating of Gum, Paste,
or other Liquid to Paper and other Flexible Substances and
Cardboard.
I JOHN JAMES ALLEN of 3 George Street, Halifax in the county of York,
Managing Director of the Allen Machine Company Limited, 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 machines to be employed for applying a coating of gum,
paste, or other liquid, to paper, or other flexible substances, and to cardboard, thereby
dispensing with the use of brushes and avoiding the waste and labour which occurs
with hand gumming.
gum
My improved machine for gumming paper, and the like flexible substances is
constructed with a gumming roller revolving in a trough containing paste or gum,
with an adjustable strickle plate or scraper (for removing the excess of from
the roller) with feed rollers and guides, for guiding and feeding the paper to the
gumming roller, with a tension cover which presses the paper on to the gumming
roller, as it passes between, and thereby insures the covering of the whole surface with
gum or other liquid, fingers are provided to lift the paper from the gumming roller,
from which it passes over the finishing roller.
When cardboard or similar inflexible substances is required to be gummed, the
tension bar is removed, and the tension roller and the top feed roller are raised, and
adjusted to the required height so that the cardboard can be fed horizontally through
the machine, and operated upon as described.

Fig. 3 is a cross section of Fig. 1, through the line A. B.
Fig. 4 is a cross section of Fig. 1 with tension bar removed, and tension roller
raised for gumming card board, or other stiff material.
C is the frame of the machine having a trough D, with lid D¹, by the extension
of the trough at one end D2, provision is made for a continuous supply of liquid to
the trough from an airtight cistern. E is the gumming roller, revolving within the
trough D which contains paste or gum; F is the adjustable cover, to which is attached
the strickle plate F¹, which regulates the layer of liquid, and keeps down all superfluities
in the trough.
G and G are the feed rollers, the top feed roller G, (having its bearings in the
slots G2) is self adjustable, and will take any thickness of paper or cardboard.
Hare the guides carried upon the tension cover in slot HI, adjusted by thumb-
screws H². J is the tension cover, which extends the whole length of the gumming
roller, and keeps the paper, down upon the periphery of the gumming roller.
K is the tension roller carried on the pivotted arms K', and adjustable as to its
height by means of the projections L', on each of the brackets L, and adjusting screws M,
with radial slots K2 on the underside of each of the pivotted arms K³, pins N bearing
in the slots K secure the tension roller in position when adjusted.
For taking the paper off the gumming roller, there are a series of fingers or take
offs P, the ends of which enter slight grooves formed at intervals around the periphery
of the gumming roller, to insure the fingers getting under the paper, the paper then
passes to the finishing roller R, over which it is quickly drawn and finished, a
strickle R and trough R2 are provided for removing and catching the froth from the
finishing-roller.
"The adjustable cover is formed with angle ends S, bearing against similar angles S',
on the frame C, and has also two angular slots S2 in which are adjustable studs S³.
The strickle plate is adjusted by the screwed spindle T with collar 'T', and-milled
head T, the collar working in the slot U of the bracket U', attached to the frame C,
the spindle. being tapped into the cover, plate, so that on turning the spindle one way
or the other, the cover plate advances or recedes nearer to or further from the
gumming roller, so: regulating by its strickle. F¹, the thickness of the layer of guin
upon the roller.'
E is the handle upon the end of the spindle of the gumming roller for operating
the various rollers by means of the gear wheel 1, driving in turns the gear wheels 2.

Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
.
1. The combination of a trough D for holding gum, a gumming roller' E revolving
therein, the strickle F, and adjustable cover plate Fwith groove for guides H,
the feeding rollers Gand G¹, in front of the gumming roller, the top feed roller
being self adjustable, the regulating guides H, the tension roller K, adjustable as to
its height, by means of the pivotted levers Kand screws, the .taking off. fingers.P,
and receptacle R2, with strickle R₁ for removing and catching the froth from the
finishing roller for the purposes substantially as shown and described.
}
2. The combination of the trough D for holding gum, the gumming roller E and
the frame C of the machine having angles S corresponding with the angles S of the
slotted cover plate F, for the purpose of adjusting the position of the strickle F¹
to the gumming roller, by means of the screwed spindle T carried in a bracket U',
attached to the machine frame. C, for, the purposes substantially as shown and
described.
33. The combination with the gumming roller E oft the fingers, or take öffs!P, and
finishing roller R, substantially as shown and described.
4. The combination of the trough ID for holding gum, the gumming roller E,
baving a self adjustable feed roller Gabove it; the adjustable tension; roller. K.mounted

page_text: upon the pivotted arms K' and finishing roller R for feeding and gumming cardboard
or other similar stiff substances, substantially as shown and described.
5. The combination of the gumming roller E, the tension cover J, the take offs P,
and the finishing roller R, substantially as shown and described.
6. The combination of the gumming roller E, the cover plate F, with angles S for
adjustment, and the finishing roller R, substantially as shown and described.
