Engineer. "NEW OR IMPROVED MACHINERY OR APPARATUS FOR MAKING ROPES
OF STRAW AND OTHER SIMILAR MATERIALS." (A communication from Christian
Söeborg and Laust Petersen, of Röskilde, in the Kingdom of Denmark.)
This Invention has for object the making of ropes of straw and other similar
materials.
The straw or material to be twisted into rope is placed in a box and the spun
material or rope is wound around a reel or drum. The spinning apparatus situate
between the box and reel or drum is arranged as follows:-Suitable feed boxes are
provided of a form tapering towards one end; material to be spun having been
placed in these feed boxes is caused to pass out through tubular guides of a tapering
form, thence through hollow axles, each carrying a driven pinion and a suitable
frame provided with a pair of grooved or channelled wheels or rolls; one wheel or
roll of each pair is pressed towards the other wheel or roll of the same pair by a
spring, so as to press against the material to be spun, which passes between the
grooved or channelled wheels or rolls, and is thereby spun or twisted as the hollow
axles are rotated by suitable gear in connection with the pinions already referred
to. The material passed between each pair of grooved or channelled wheels or
rolls forms a comparatively small rope; the two ropes are afterwards combined by
twisting into one rope, for which purpose they are caused to pass through a pair of
converging tubular guides to a third hollow axle or tubular device driven by
suitable gearing, and having a lateral opening through which the rope is caused to

page_text: pass to, and between ribbed or fluted rolls driven by suitable gear and which draw
the rope_through_the_lateral opening in the last mentioned hollow axle or tubular
device, concentrically with which is arranged a fixed spur wheel, with which is
-geared-a-spur-wheel-on-the-axis-of-one-of-the ribbed or fluted rolls, which axis is
carried by a revolving frame. Thus_as_the_frame revolves and carries the ribbed or
fluted rolls_with_it_one_of_them_is_rotated, and by suitable gear drives the other.
The said roll axis is prolonged and caused to slowly drive a drum, or nut threaded
-on-the-axis-of-the-reel,-so-as-to-cause-the-reel-to-advance-slowly-along.its.axis.as
the rope is wound around the reel, to which it is conducted through suitable guides.
Means-are- provided for adjusting the pressure of one ribbed or fluted roll in the
direction of the other, so as to squeeze the rope more or less tightly between the
pair.

HEINRICH CHRISTIAN PETERSEN, of Copenhagen, in the Kingdom of Denmark,
Engineer. "NEW OR IMPROVED MACHINERY OR APPARATUS FOR MAKING ROPES
OF STRAW AND OTHER SIMILAR MATERIALS." (A communication from Christian
Söeborg and Laust Petersen, of Röskilde, in the Kingdom of Denmark.)
Fig. 1 shews in side elevation a machine, according to this Invention, for making
ropes of straw and other similar materials; Fig. 2 is an end view, and Fig. 3 a
plan of the machine; Figs. 4 and 5 are detail views. The straw or material to be
twisted into rope is placed in a box a, and the spun material or rope is wound
around a reel or drum b. The spinning apparatus is situate between the box and
reel or drum, and is arranged as follows:-c, c', are feed boxes of a form tapering
towards the reel or drum; material to be spun having been placed in these feed
boxes in suitable quantities is caused to pass out through tubular guides d, d', of a
tapering form, thence through hollow axles e, e¹, each carrying a driven pinion f, ƒ¹³,
and a suitable frame g, g', provided with a pair of grooved or channelled wheels or
rolls h, h, h, h; one wheel or roll of each pair is pressed towards the other wheel
or roll of the same pair by springs i, as illustrated in Figs. 4 and 5, so as to press
against the material to be spun, which passes between the grooved or channelled
wheels or rolls (at x, x, Fig. 5), and is thereby spun or twisted as the hollow
axles e, e', and frames g, gl, are rotated by suitable gear k, l, m, in connection with
the pinions f, f¹, already referred to. The shaft m¹ may be driven by hand, as
shewn, or be provided with fast and loose pulleys and a belt-shifter, and be driven
by steam or other power. The material passed between each pair of grooved or
channelled wheels or rolls forms a comparatively small rope; the two ropes are
afterwards combined, by twisting, into one rope, for which purpose they are caused
to pass through a pair of converging tubular guides n, n¹, to a third hollow axle or
tubular device o forming one end of the drum or reel axle, and which is driven by
the spur wheel p and pinion q, and has a lateral opening o' through which the rope
is caused to pass to, and between ribbed or fluted rolls r, r', driven as presently
described. These ribbed or fluted rolls draw the rope through the lateral opening o¹
in the said hollow axle or tubular device o. Concentrically with this hollow axle
is arranged a fixed spur wheel t that does not rotate with the axle, and with such
fixed wheel is geared a spur wheel u on the axis of one (1) of the ribbed or
fluted rolls, which axis is carried by a compound fly-frame F keyed on and
revolving with the axle o. Thus, as the frame F revolves and carries the ribbed or
fluted rolls r,, with it, the one r¹ is rotated; its axis 2 has fixed on it a toothed-
wheel in gear with a similar wheel fixed on the axis of the other ribbed or
fluted roll r, which is thus simultaneously revolved, but rotates the opposite way
tor. In order to wind the rope regularly on the reel and obtain a measurement
of the length of the rope, advancing motion is imparted to the reel along its axle
as follows:-The roll axis 2 is prolonged as shewn and fitted with a band-wheel v,
which, by a belt or band v¹, drives slowly a drum or nut D forming the reel nave,
which is formed with an internal screw thread fitting an external thread cut on
the axle o, so as to cause the reel to advance slowly along its axle as the rope R is
wound around the reel, to which it is conducted through suitable eyes or guides y.
z is a spring for adjusting the pressure of one ribbed or fluted roll in the direction
of the other, so as to squeeze the rope between the pair 7, r². To obviate irregu-
larity in working consequent upon inequality in the supply of the material the fly
frame F is provided with an adjustable counterweight F'.
Having described the nature of the said Invention, and explained in what
manner the same is to be performed or carried into practical effect, I hereby declare

page_text: that what I consider to be novel and original, and therefore claim as secured to me
-under-the-Letters Patent hereinbefore-in-part recited is,--
1. The arrangement in combination of the feed boxes c, c', tubular guides d, d¹
-hollow-axles-e,-e¹, frames g, g, grooved or channelled wheels or rolls h, k, h¹, h, and
their operating-gear, substantially-as-and for the purpose described.
--2--The-arrangement in combination of the hollow axle or tubular device o
operated as described, the fly frame F, fixed toothed wheel t, toothed wheel u, and
ribbed or fluted rolls, all-operating-together-substantially-as-and-for_the
purpose described.
3. The method of causing the reel or drum to move along its axle as rope from
between the ribbed or fluted rolls r, r, is wound upon it, substantially as and for
the purpose described.
4. The improved machine constructed, arranged, and operating substantially as
shewn in and described with reference to the accompanying Drawings, for making
rope of straw and other similar material.
In witness whereof, I, the said Heinrich Christian Petersen, have hereunto set
my hand and seal, this Thirteenth day of December, in the year of our
Lord One thousand eight hundred and seventy nine.
