I JOHN HOLROYD of Tomlinson Street Manchester in the County of Lancaster,
Engineer and Machinist do hereby declare the nature of this Invention to be as
follows:-
My Invention relates to apparatus adapted to be employed to coat one side of paper
or material with gum, paste or adhesive cement as for example the apparatus to which
my invention more particularly refers is suitable to be employed in the gumming or
pasting of paper labels. In the said apparatus a label to be gummed is fed forward
over a plate by means of a feed roller and is brought into contact with a revolving
cylinder which dips into the gum or cement and coats one side of the label as it passes
through the machine. In my improved apparatus I feed in the label by means of a
"rubber" covered roller which acts in conjunction with a yielding pressure plate
which is so supported or suspended as to tend to move into contact with the said
The
roller or is acted upon by a spring or by springs to obtain the same result.
said roller and the curved plates which partly cover the gumming roller are carried
by hinged arms the said plates connecting together the said arms so as to form a
frame which when loosened can be raised and turned over on its hinges to give clear
access to the gumming roller. The said presser plate is extended forward so as to
constitute the feed table of the machine and is provided with an adjustable gauge or
stop which serves as a guide when gumming paper or material for a limited distance
from the edge. In some cases this adjustable gauge may be dispensed with. I prefer
to form the lower receptacle or reservoir with a projecting feed hopper through which
the said receptacle can be supplied with gum or fluid cement without removing the
gumming roller or feed plates."

Improvements in Gumming or Pasting Apparatus for Labels and
Sheets of Material.
I JOHN HOLROYD of Tomlinson Street, Manchester, in the County of Lancaster,
Engineer and Machinist, 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 and accompanying drawings:
My Invention relates to apparatus adapted to be employed to coat one side of paper
or material with gum paste or adhesive cement as for example the apparatus to which
my invention more particularly refers is suitable to be employed in the gumming or
pasting of paper labels. In the said apparatus a label to be gummed is fed forward
over a plate by means of a feed roller and is brought into contact with a revolving
cylinder which dips into the gum or cement and coats one side of the label as it passes
through the machine. In my improved apparatus I feed in the label by means of a
"rubber" covered roller which acts in conjunction with a yielding pressure plate
which is so supported or suspended as to tend to move into contact with the said
roller or is acted upon by a spring or by springs to obtain the same result. The
said roller and the curved plates which partly cover the gumming roller are carried
by hinged arms the said plates connecting together the said arms so as to form a
frame which when loosened can be raised and turned over on its hinges to give clear
access to the gumming roller. The said presser plate is extended forward so as to
constitute the feed table of the machine and is provided with an adjustable gauge or
stop which serves as a guide when gumming paper or material for a limited distance i
from the edge. In some cases this adjustable gauge may be dispensed with. I prefer
to form the lower receptacle or reservoir with a projecting feed hopper through which
the said receptacle can be supplied with gum or fluid cement without removing the
gumming roller or feed plate.
In the accompanying drawings which are illustrative of my invention Fig. 15
represents an end view of the complete apparatus.
Fig. 2 is a cross section of the same.
Fig. 3 is a plan.
Fig. 4 is a front elevation.
In the said Figs. a is the said feed roller bis the presser plate c is the hinged a
frame and d is the adjustable gauge. The frame c is mounted upon screws e e which
are screwed into the ends of the trough fand serve as pivots or fulcra upon which the
frame turns when it is raised away from the gumming cylinder g. In the frame c
are formed bearings for the journals of the feed roller a. This roller is covered with
"rubber" so as to have a yielding surface and is rotated by means of a spur wheel h
which gears with a pinion i which is fixed upon one end of the roller shaft. Upon
the front of the trough f is mounted the feed and presser plate b. The manner in
which the said plate is mounted is indicated by Fig. 5. Upon the ends of the plate
are studs or projections which rest in recesses or seatings in the upper edge of the

page_text: trough and serve as fulcra. Owing to the positions of these fulcra the plate acts as a
lever the front portion of the plate forming the longer and heavier arm of the lever
and as a consequence the back or inner part of the plate bears upward with a yielding
pressure upon the feed roller a. To adjust the apparatus for use the hinged frame is
brought down until the feed roller presses to a suitable degree upon the plate b. The
frame is then secured by tightening screws k k at the ends of the trough. The curved
guiding and covering plates are attached to the hinged frame so that when the
latter is raised the gumming roller is freely exposed and can be lifted out of its place.
The adjustable gauge d can be adjusted in position upon the plate and be secured by
means of a screw m. This gauge serves as a guide when the apparatus is being used
in the gumming of paper or material for a limited distance from the edge. The
trough which serves as a base for the machine and also as a receptacle for the gum
or cement as is usual is formed or provided with a projecting feed hopper n. When
it is desirable to supply the trough with gum or paste or other fluid cement such
matter is poured into the hopper and passes through a hole or through holes into the
trough. When the apparatus is not in use the whole of the upper part is covered by
a removable lid not shown in the drawings whereby dust and dirt is excluded from
the rollers and trough.
I am aware of the existing patent No. 13,383 of 1885 granted to John James Allen,
and I make no claim in respect of the parts which form the subject matter of the
claims attached to the specification of the said patent.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :—
(1) The combination of the hinged frame carrying the feed the presser and the
gauge with the other parts of the machine the whole constituting a gumming or
pasting machine substantially as set forth and indicated.
(2) As means for feeding in the labels or paper or material in a gumming or
pasting machine the feed roller a acting in concert with the yielding presser plate b
substantially as set forth and indicated."
(3) The adjustable guage d for the purposes and substantially as described and
shown.
