JOHN JAMES ALLEN of Halifax in the County of York Insurance Broker
"IMPROVEMENTS IN APPARATUS FOR FEEDING AND FOR GUMMING, VARNISHING,
COLORING, SIZING, PASTING AND OILING SHEETS OF PAPER AND LABELS."
This Invention relates to further Improvements in apparatus for purpose
aforesaid for which Letters Patent N° 2096. A.D. 1881 were granted to me.
Firstly to improved apparatus for cleaning the rollers or parts employed from
superfluous gum or other liquid deposited thereon.
Secondly to improved apparatus for supporting and guiding the endless bands or
sheets which carry the paper or labels.
Thirdly To improved apparatus for gumming, sizing, varnishing or coloring
sheets on both surfaces.
Fourthly. To improved apparatus for feeding and guiding gummed or pasted
labels to bottles
Fifthly To improved apparatus for removing the sheets from the gumming
roller
Apparatus for cleaning and removing waste or superfluous gum varnish or colour
comprises a roller working in close contact with the gumming varnishing or
coloring roller to the roller first referred to is applied a "doctor" or "doctors
angled from the centre of its length or parallel to the roller and having a trough
or receiver in connection therewith An endless sheet of woven fabric (or of india
rubber) is passed over guide rollers so as to cause the fabric (or rubber) to bear
upon and against the roller and cleanse and dry the same. In some casses I slightly
corrugate or chase the circumferential surface and employ a cleaning brush in lieu
of the woven fabric or in addition thereto. Another construction comprises a
contract roller partly enclosed or received within a trough the latter containing a
pad or pads of fibre or sponge which bear on and clean and dry the contact roller.
And another modification is to cover the contact roller with flannel or woven
fabric and remove the gum or other liquid gathered thereby through the agency of
a presser edge or knife bearing on the covering of the contact roller aforesaid.

For the purpose of introducing the paper to the rollers which supply thereto the
gum color or other liquid and to secure the requisite strength and close contact
between the feeding instrument and the said roller or rollers I employ a "saddle
or wedge shaped guide over one end of which the endless sheet carrying the paper
to be operated upon is passed the saddle being introduced close to the gumming or
coloring roller or where two rollers are used, the saddle is introduced close to the
nip of the two, so securing short distance of delivery and at the same time giving
a firm and rigid support to the endless sheet which a roller of small diameter would
not afford
For the purpose of supplying gummed labels direct to bottles the labels as
gummed or pasted pass to an endless cloth or endless band over and above which
band is a revolving roller and guage which answers the purpose of a rest and also
to revolve (in case of cilindrical bottles) bottles which are placed on the endless
band so that the labels are by the said band carried under and applied to the
bottles the latter are removed as the labels are applied thereto
The instrument employed for guiding and turning the sheets as gummed from
the gumming roller comprises a comb or row of projecting teeth in combination
with which is a brush or lines of bristles the latter smoth the.gum on the paper and
give finish and smothness to the work.
