COMPLETE SPECIFICATION.
Apparatus for Labelling or Covering Boxes and similar Objects.
I, FERDINAND EMIL JAGENBERG Manufacturer, of Reichsstrasse, Düsseldorf,
in the German Empire, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to machines for applying labels to boxes, and is illustrated
by the accompanying drawings, in which Fig. 1 is a side elevation, and Fig. 2.a
plan, of a labelling machine embodying my invention; while Figs. 3, 4, and 5
represent the principal parts on a larger scale.
The machine comprises in its construction an endless belt r, upon which the
rectangular boxes to be labelled are placed upright in a row, and which runs over
a pulley mounted on a horizontal shaft w. The latter may be set in motion by
a belt pulley, or by a crank.
The labels are placed upright in a guide channel m situated on one side of the
travelling band r.
The boxes are carried forward by the belt until the first abuts against a cross.
rail 9. This rail carries a slide s connected with a helical spring f and adapted to
be pressed forward (rectangularly to the belt r) by a cam a fixed on the said
driving shaft w.
The slide s carries a rectangular abutment a adapted to meet the foremost box,
so as to push the same aside and in front of the glue receptacle l. The latter
consists of a funnel provided at the bottom with an aperture, which has the same
height as the box. This aperture is kept closed by the box itself, which has been
pushed sideways and is held in front by the rail g. After the first box has been.
placed in front of the glue receptacle, the slides, again recedes and the second box
arrives before the abutment a and is also pushed aside.
By this lateral motion of the second box, the first box is pushed in front of the
guide channel m for the labels. This channel contains a sliding rod c actuated by
a helical spring b.
The said guide channel, together with the sliding rod, with which it is connected
at the back by an angle or flange k and a lug or standard k', is adapted to turn on
a horizontal axle d, so that the rear end of the guide channel may descend as.
shown by Fig. 4. This descent is, however, prevented by a spring e which tends
to keep the channel in a horizontal position, as represented .by Fig. 3.
In pushing the box sideways the rear end of the guide channel m is caused to
descend (Fig. 4) by means of a tooth w¹ mounted on the shaft w, said tooth coming
in contact with an arm h¹, which, when turning on its fulcrum, acts against the
front end of a bar h carrying at its rear end a hinged eyepiece i, through which
passes the sliding rod c mentioned above, and to which is attached the rear end of
the spring e.
As the channel m descends, the eye-piece i assumes an inclined position (Fig. 4)
and thereby clamps the sliding bar c, so as to draw the same backward until the
eye-piece abuts against the set screw o, screwed into the flange k.
As the arm h¹ pushes the rod h still further back, the latter, together with the
sliding rod c, descends at the rear end (Fig. 4).
Owing to the inclined position of the channel m, after the foremost label has

another box has been pushed sideways in front of the labels.
If now the tooth w¹ gets clear of the arm h, the spring e lifts the channel again,
and the spring b is again able to press the labels against the box, so that the
foremost label sticks to the glued face of the box. When the channel again
descends the remaining labels fall back, while the box to which the label has
just been applied, is pushed down sideways by the slides and the succeeding
boxes.
Instead of ordinary labels, other leaves or sheets may be glued or gummed on,
instead of rectangular boxes plain cards or plates may be thus provided with
labels.
Instead of an endless transporting band r, other known feed mechanisms may be
employed, and the liquid glue or gum may be replaced by other suitable adhesive
substances.
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
claim is
1. Apparatus for applying labels or other sheets to boxes, comprising in its
construction a transporting band adapted to carry the boxes, a slide (s) movable
transversely to the said band, a giue receptacle (1) provided with a suitable outlet,
and a guide channel (m) for the labels, the whole being arranged and adapted to
operate substantially as described.
2. In a labelling machine of the kind specified, a pivoted feed and guide
channel (m) adapted to descend at its rear end, after the foremost of the row of
labels contained in the said channel has been applied, and thereby to place the
remaining labels in a slanting position, substantially as described.
3. In a labelling machine of the type specified, the combination of a pivoted
feed channel m and sliding rod c, with the device for tilting the said chaunel and
withdrawing the slide, comprising a rod h adapted to be pushed back by the
driving shaft w, and a pivoted eye piece i situated on the sliding rod c, said eye-
piece being caused to assume a slanting position by the motion of the rod h and
thereby to clamp the rod c, so that the latter takes part in the motion of the rod h
until arrested by a set screw o, after which the rod h causes the channel to descend,
substantially as described.
