Improvements in Paper Twine Machines.
I, GEORGE LOOMIS BROWNELL, of Worcester, in the County of Worcester,
and State of Massachusetts, United States of America, 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:
My invention relates to a machine for forming a cord, or twine, from a flat
strip, or ribbon of paper, either with, or without a central core of metallic wire.
In the following description reference is made to the following figures in the
accompanying drawings, which represent such portions of the mechanism, as is
necessary to illustrate the nature of my present invention and in which :-
Figure 1 represents in side elevation a view of the operating mechanism, by
which the paper strip is formed into a twine, or cord, having a central core of wire,
a portion only of the supporting frame-work being represented.
Figure 2 represents a front view of the twine forming mechanism, shown in side
view in Figure 1.
Figure 3 shows a top view of the device for moistening the paper strip, or
ribbon.
Figure 4 is a perspective view of the forming tube and also of the concentric
cylinder, around which the paper strip is wound.
Figure 5 is a central, sectional view of the forming tube showing the relative
position of the cylinder, upon which the paper strip is wound and
Figure 6 represents the same view shown in Figure 5, with the addition of the
paper strip showing the crimping and twisting operation, as the paper is carried
through the forming tube.
In the drawings, A denotes a portion of the supporting frame-work; B denotes a
trough containing the roll of paper ribbon, from which the cord, or twine is to be
made and forming a pocket, which in the mechanism represented in the accom-
panying drawings, is arranged to support the coil B¹ of
paper ribbon.
Attached to and depending from the frame-work of the machine, is a plate C to
which is attached the forming tube D, having a bore D' throughout the greater
portion of its length, the circumference of which is equal to the width of the paper
strip, or ribbon. At the upper end of the forming tube, the bore is reduced in
diameter, forming an outlet D and within the larger bore D¹, I place the cylinder E
around which the paper strip, or ribbon is spirally wound, as it enters the forming
tube D; the cylinder E being of less diameter than the bore D', so as to provide
an annular chamber F to receive the strip of paper. The cylinder E is provided
with a concentric hole E' extending throughout its entire length, through which
the wire passes to form the core of the paper twine. The concentric hole E', is
coincident with the outlet D' aud also with the axis of rotation of the flyer frame J.
The cylinder E is supported in a yoke G in which it is capable of a vertical
adjustment by means of a set screw G¹. To the ends of the yoke G, I attach
cords G which are carried over pulleys Gaud support at their opposite ends
counter-weights G, by which the yoke G is held against the pins G projecting
from the face of the plate C. It is desirable that the upper end of the cylinder E,
should be maintained at such a distance from the contracted outlet D', as will allow
the paper wound around the cylinder E and within the annular chamber F, to be
properly crimped and twisted, without clogging the passage through the forming.
tube.
The annular chamber F, and the outlet D2 are connected by the short section
having inclined, or tapered sides H, against which the paper tube is drawn, as it

page_text: leaves the annular chamber F and enters the outlet D³, thereby reducing its
diameter and longitudinally crimping its surface as represented at I, Fig. 6.
As the paper tube is delivered from the outlet D2, it is conducted to twisting and
winding mechanism, which may be of any known form of construction, that shown
in the accompanying drawings consisting of a rotating flyer frame J, carrying scored
drums J, J, and a concentric winding spool K. This portion, of the mechanism,
however, forms no part of my present invention, it having been shown and described
in the Patent granted to me, in Great Britain, said Patent being numbered 4674
of 1891; but the twisting and winding mechanism employed in any of the known
machines for making cord, or twine can be employed for the purpose.
Upon a bracket L is a water-trough L' supporting a roll L, partially immersed
in the water and a weighted roll L', between which rolls, the paper strip is con-
ducted from the coil B₁ to the cylinder E. The paper strip, or ribbon is carried
beneath the staple M, which is placed at one side of the cylinder E and slightly
inclined, so as to deliver the paper at an angle with the axis of the cylinder E as
represented in Figures 2 and 6. around which the paper strip is wound in spiral
coils, which are inclosed within the annular chamber F.
At the lower part of the machine is a spool support N, held upon a rotating
spindle N¹ placed directly beneath the flyer frame J, with its axis coincident with
the axis of the flyer frame and preferably rotated at the same rate of speed as the
flyer frame J. Upon the spool N, is wound the wire O, which is conducted through
the upper and hollow end of the spindle N₁, entering the spindle by the hole a and
passing through the hole E', in the cylinder E, forms a core around which the
strip of paper is compressed and twisted by the mechanism already described.
I do not, however, confine myself to any special mechanism for carrying or
delivering the metallic wire O to the mechanism by which the paper twine is
formed.
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 :
First. The forming tube D provided with a cylindrical bore D¹, an outlet D'
with its axis coincident with the axis of said bore, but with its diameter reduced and
having the inclined, or tapered sides H uniting said bore and said outlet, sub-
stantially as described..
Second. The combination with a forming tube D, provided with a cylindrical
bore D and an outlet D³, of a cylinder E held within said tube and forming an
annular chamber F, substantially as described.
Third. The combination with twisting and winding mechanism, by which the
paper strip, or ribbon is twisted and drawn through the forming tube, of a forming
tube D having a cylindrical bore D' and an outlet D2, with its axis coincident with
the axis of said bore, and a cylinder F held concentrically within said tube, the
axis of said cylinder F being coincident with the axis of rotation of the twisting
mechanism, substantially as described.
Fourth. The combination with a forming tube D, provided with a cylindrical
bore D' and an outlet D³, of a cylinder E held concentrically within said tube,
forming the annular chamber F, said cylinder being provided with a central hole E'
extending throughout its length, substantially as described.
Fifth. The combination with mechanism by which a paper strip, or ribbon is
drawn through a forming tube and twisting mechanism by which said paper strip,
or ribbon is twisted, of a forming tube D, a cylinder E held concentrically within
said forming tube and having a central hole E' extending its entire length and
mechanism for holding and rotating the wire which is carried through said centrul
hole to form the core of the twisted cord, or twine, substantially as described.
Sixth. The combination with mechanism for twisting the paper cord, or twine,
and drawing the same through the forming tube, of a forming tube having a bore D'
and a contracted outlet D2, a cylinder held concentrically within said tube and forming

page_text: an annular chamber and means by which said cylinder is adjustably supported
within said forming tube, whereby the position of said cylinder is varied with
reference to the contracted outlet of the forming tube, substantially as described.
