Improvements in and connected with Mechanism for Pasting the
Bottoms of Paper Bags, Pasting or Gumming Labels, and such
like.
I, WILLIAM CARTER, of 62, Bothwell Circus, Glasgow, Lithographic Printer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to a simple device for pasting down the folded parts at
the bottoms of paper bags, for pasting or gumming labels, and such like.
In carrying out the invention I construct a table of any suitable material and
fit thereon an oblong or other desired form of paste vessel having a movable front
gate. Working in guides along the bottom of this vessel is a flat tongue or blade
which, when necessary, can be shot forward out in front of the paste vessel and
then drawn back again within it by means of lever mechanism connected to a cross
shaft underneath the table which latter is acted upon by treadle or other mechanism
and by a spring or such like.
The arrangement is such that when it is desired to paste down the triangular
shaped folded-over-parts at the bottom of the bag, the tongue, with paste on
its_upper side, is shot forward under the action of the treadle or the like over the
bottom part of the bag and the triangular parts can then be easily folded over on
top of the tongue so as to take the paste therefrom, whereupon the tongue is with-
drawn, by relieving the treadle, and the triangular parts merely pressed tightly
down on the bottom of the bag by the fingers.
By raising or lowering the gate of the paste vessel the amount or thickness of
paste on the tongue can be regulated.
As it is necessary, in the case of glazed or thick paper bags, to keep them
pressed for some time in order to make the paste adhere firmly, I provide
at the front or other part of the table, a pressing board consisting of a strip of
wood or metal which at each end is held tightly against the underside of the table
by means of rubber or other springs or equivalent. This board has a guide way
in it. The table is also recessed or cut out to enable the newly pasted bags to be
inserted in the guide way and between the board and the table so as to be sub-
jected to pressure. The newly pasted bags are placed in the guide way one after
the other until they gradually fill it when they, one by one, as fresh bags are
inserted, tumble over at the end of the guide into a receptacle.
The parts of the mechanism are made removable so as to readily wash off paste
or dirt.
Two or more pasting devices can be arranged together on a single table or bench.
Receptacles for the bags to be pasted may be provided.
The invention is applicable also for pasting or gumming labels and such like.

I, WILLIAM CARTER, of 62, Bothwell Circus, Glasgow, Lithographic Printer,
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 a simple device for pasting down the folded parts at
the bottoms of paper bags, for pasting or gumming labels, and such like.
In carrying out the invention I construct a table of any suitable material and
fit thereon an oblong or other desired form of paste vessel having a movable front
gate. Working in guides along the bottom of this vessel is a tongue or blade
which, when necessary, can be shot forward out in front of the paste vessel and
then drawn back again within it by means of lever mechanism connected to a cross
shaft underneath the table which latter is acted upon by treadle or other mechanism
and by a spring or such like.
The arrangement is such that when it is desired to paste down the triangular
shaped folded-over-parts at the bottom of the bag, the tongue, with paste on
its upper side, is shot forward under the action of the treadle or the like over the
bottom part of the bag and the triangular parts can then be easily folded over on
top of the tongue so as to take the paste therefrom, whereupon the tongue is with-
drawn, by relieving the treadle, and the triangular parts merely pressed tightly
down on the bottom of the bag by the fingers.
By raising or lowering the gate of the paste vessel the amount or thickness of
paste on the tongue can be regulated.
As it is necessary, in the case of glazed or thick paper bags, to keep them
pressed for some time in order to make the paste adhere firmly, I provide,
at the front or other part of the table, a pressing board consisting of a strip of
wood or metal which is held tightly against the underside of the table
by means of rubber or other springs or equivalent. This board has a guide way
in it. The table is also recessed or cut out to enable the newly pasted bags to be
inserted in the guide way and between the board and the table so as to be sub-
jected to pressure. The newly pasted bags are placed in the guide way one after
the other until they gradually fill it when they, one by one, as fresh bags are
inserted, tumble over at the end of the guide into a receptacle.
And in order that my said invention may be properly understood I have here-
unto appended two explanatory sheets of drawings, whereon,
Fig. 1 is an end view of the apparatus.
Fig. 2 is a plan.
Fig. 3 is a detail view.
Fig. 4 is a part section on the line - Fig 2.
Fig. 4 is a detail view.
Fig. 5 is a plan view and Fig. 6 an end view to an enlarged scale of the paste
vessel.
Referring to the drawings whereon the same reference letters wherever
repeated indicate the same parts.
a is the table of the machine and, as shown, it is supported upon suitable
standards b, b¹. c is the paste vessel which is secured removably by screws c¹ to
a plate d let into the table a (see particularly Figs. 5 and 6). ³ are flanges at the
bottom of the paste vessel. The paste vessel is made with vertical guides c³, c³,
in which is movably fitted a front gate 5. This gate can be adjusted to any

page_text: lesired position in the guides c³, c, so as to regulate the outflow of the paste and
e is the movable
when adjusted can be clamped in position by the screw co.
ongue or blade which, as shown, may be of triangular shape. This tongue can
lide back and forward along the bottom of the paste vessel. In Fig. 5 the full
ines show the tongue in its back position whilst the dotted lines el indicate its
but or forward position.
The mechanism for actuating the tongue e consists of a double bell-crank
lever f which is fulcrumed at fi to a downwardly projecting arm 9 attached to
the underside of the plate d. The upper ends of the double bell-crank lever f are
forked as shown at få Attached to the short arm of the lever f is a wire or band h
which extends downwards to a treadle i. j is a spring which brings back the
lever after each depression of the treadle 2.
k is an opening cut in the table a.
The tongue e is connected to the bell crank f by means of a swivelling double
armed link el. e², e², are the arms of the link. 2 is a stop on the plate d.
The mechanism for pressing the paper bags after being pasted consists of the
board which is provided with a guard plate 11 at one side. As shown clearly at
Figs 1, 2 and 3 the board is pressed upwards against the bottom of the table
by means of a spiral spring m. This spring, at its upper end, is fitted in a recess
in the bottom of the board 1, and, at its lower end, is held in place by means of a
pin n which is secured within a slot o in a bracket p attached to the underside of
the table (see Fig. 4). The pin n is clamped in position within the slot o by means
of the screw q.
The detail view Fig. 4 shows the pin and method of its attach-
ment to the bracket p clearly. In this view n¹ is a square made on the lower
end of the pin so as to prevent it turning round in the slot o.
attached to the side of the board for the purpose of depressing it easily. As
will be seen the end 13 of the board 7 is slightly curved at its upper side, and, as
will also be seen, the table is recessed at a¹ and the side a² of the recess is curved
and faced with brass or other metal.
r is a block
s is a plate fitted on the table a and having an upturned edge s¹. The bag
bottoms, after being pasted, are pressed and flattened on this plate s.
t is a receptacle for the bags, labels, etc., to be pasted.
If desired a paster with its accessories can be fitted at each end of the table a.
The arrow at Fig. 3, indicates the direction in which the bags after being
pasted are inserted in the presser and the arrow u indicates the direction taken
by the bags as they tumble over the inclined end 3 of the presser board.
For different sizes of bags different sized tongues and gates with corresponding
openings would be employed.
The bottoms of tea bags, labels, etc., can be very speedily pasted with this
apparatus.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
consider novel and desire to claim is :-
1. A pasting device comprising, in combination, a paste vessel, a gate in the
vessel, a reciprocating tongue or its equivalent at the bottom of the vessel, and
means for reciprocating the tongue, substantially as set forth.
2. The device for pressing the bags after being pasted, substantially as herein-
before described with reference to the drawings annexed.
3. The general arrangement and combination of parts of the pasting machine,
substantially as hereinbefore described and shown on the drawings annexed.
Dated this 3rd day of February 1898.
