COMPLETE SPECIFICATION.
Improved Machine for Securing in Position the Bottoms of Paste-
board Boxes and the like.
I, MORITZ HEINEMANN of Bielefeld, Prussia, in the Empire of Germany,
Manufacturer, 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 refers to machines for securing in position the bottoms of paste-
board boxes and the like by means of a strip of gummed paper or serrated sheet
metal that is pressed upon the adjacent or meeting edges of the bottom and the
paste-board sides of a box by a roll or rolls of suitable shape. My improvements
particularly relate to the means for supporting the round or oval paste board
ring which constitutes the sides of the box, and for rotating the latter together
with, or upon, said supporting means, for the purpose of effecting the union of
the bottom and the ring in a quick and reliable manner by very simple
mechanisms.
In order to make my invention more clear, I refer to the accompanying
drawing, in which similar letters denote similar parts throughout the different
views and in which :-
Figure 1 is a side elevation, partly in section of my improved machine.
Figure 2 is a front elevation of the same, the foot of the frame being broken
away.
Figure 3 is a rear elevation of the machine.
Figure 4 shows portions of the principal working parts of the machine together
with the united paste board parts on an enlarged scale.
Figure 5 shows a modified construction of said working parts.
Figure 6 represents another form of construction, and
Figure 7 a third modification.
Referring to Figures 1 to 4 g designates the frame of the machine, the upper
horizontal arm g2 of which consists of two parallel parts holding between which is
pivoted a radially adjustable arm r, carrying at its end, a grooved roll p, p¹.
A spring 2, carried by the framing presses said arm against the end of a screw t,
supported in the downwardly extending front end of the arm g, and is provided
with an adjusting hand wheel t¹. The roll p with its groove p¹ (which latter is
angular or V-shaped in section) may thus be raised or lowered by turning the
screw t or the hand wheel t', respectively, in one or the other direction. The paste
board ring 2, which is to be provided with a bottom b, is supported by a rotating
horizontal shaft q, having a necked or reduced end q', turning in suitable bearings
in the frame g, and furnished at its rearwardly projecting end with a toothed
wheel g. This shaft or cylindrical support y may, if desired, be furnished with an
additional support in the form of the bracket g¹.
When a bottom is to be secured to a paste board ring, which constitute the sides
of a round or oval box, the arm r, is first moved away from the support q, by
turning the screw t, t' outwardly and allowing the spring t to act on the underside
of the said arm. The paste board ring is then placed upon the said support and
the bottom b, placed against the edge of the ring z. The arm r, is again lowered
so as to bring the roll p down upon the two parts in question and clamp one to the
other by means of its groove p¹. One end of the strip of gunmed paper or

page_text: serrated sheet metal is then put under the roll p, or into the groove p¹, and there
fixed by slightly turning the roll p by hand so as to press said end upon the
parts m, and z, and thus to commence the union of said parts.
The support g, is now rotated by any suitable mechanism placed in connection
with the cog-wheel q2, but I wish it to be understood that I do not confine myself
to operating the support q, by cog-wheels or any sort of toothed gearing, as it is
evident that wheels or ropes may as well be employed, and that a treadle or like
gear may be used as the driving power.
The cylindrical support g, whilst thus being rotated carries round with it the
paste-board ring and also, through the medium of the grooved roll p, p', (which in
its turn is rotated from the paste board ring z) the bottom b.
The box parts b and z may be guided and held in proper contact, by any suitable
means, and means may also be provided for guiding the strip of paper or sheet
metal onto the adjacent edges of the sides and bottom of the box and for
supporting these last named parts. In Figure 4, m' designates such a strip that
has already been fixed to the bottom b, and the ring 2, and has connected the
said two parts securely together. The strip m, may be employed in pieces of
suitable lengths, just as required for the circumference of the round or oval box,
or it may be drawn off a roll up which a continuous length has been wound.
It is not essential that the support g, should have a horizontal position, but it
may, if desired, be arranged vertically, as shown in Figure 5. The mechanism
for operating the parts p, and q is in all material respects exactly the same as
before described.
In the second modification shown in Figure 6, the support q, is formed by
a roll, whose periphery is wedge shaped in cross section. The wedge fills up the
groove pl, of the roll p, at the point of contact of said parts 9 and p. The
manner of operation in this form of construction is just the same as before
described.
It has been shown in Figure 6 that the support 9 may well be replaced by
a roll, and it is shown in Figure 7 that the roll p may well be replaced by a roller
arranged above, and parallel to, the support q. The outer end of the roller pis
furnished with a collar p³, that takes over the rim of the bottom in exactly the
same way as is the case with the lower half of the groove in the roll p Figures 1
and 4.
I wish it finally to be understood that the paste board ring z, and bottom
need not necessarily be rotated by the support g, or its equivalent, but may equally
well be rotated from the roll p, in which event the said roll is driven by any
suitable mechanism..
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
In a machine for securing in position the bottoms of paste-board boxes and the
like, the combination with a rotatable support for the paste-board ring constituting
the sides of a box, of rotatable means adapted to take over the adjacent edges of
said ring and the bottom to be secured thereto and means for rotating the said
paste-board ring with its bottom, substantially as described.
Dated this 14th day of May 1896.
