IMPROVEMENTS IN MACHINES FOR SHEARING ROPES
Year: 1884

page_text: I, PIETER MONTAUBAN: VAN.SWYNDREGT, of the firm of De Wed, Cool & Zoon;
of Kralingen near Rotterdam, in the Kingdom of Holland, Rope Manufacturer, do
hereby declare the nature of my invention for "IMPROVEMENTS IN MACHINES FOR
SHEARING ROPES" to be as follows:-
My invention relates to improvements in machines for shearing or clipping ropes,
and more especially to such inachines as are described in my Patent No 1405, of
March 16th, A.D. 1883; and the objects of my improvements are first, to cause the
principal parts of the machine as described in the said Patent No 1405 of 1883 to
rotate around their axes and, simultaneously, around the rope; instead of the rope
being rotated while passing the inachine; second, to provide suitable means for
such rotary motion; and third, to adjust the working parts of such machine
correspondingly with the thickness of the ropes to be sheared.
t
The shearing mechanism, composed of a stationary flat knife and revolving
helicoidal knives, and the brush roller of the same shape as they are described in
my said former Patent, are enclosed within a cylinder, through the centre of which
passes the rope to be 'sheared and which is turned by a belt or strap comuiunicating
the rotary motion of a pulley driven by hand or machinery. The cylinder is
provided with hollow pivots for passing the rope, and such pivots are running in
suitable bearings fixed to the frame or stand of the machine.
A fixed disc or pulley having a notch or groove in.its circumference, is contrally
placed in front of the rotating cylinder containing the clipping mechanism and the
revolving brush, and an endless strap laid in the groove or notch of said disc passes
over slantly placed guiding rollers to the pulleys of the brushi roller and the shaft
whereon the helicoidal knives are fastened thus transmitting the rotary motion of
the cylinder to the said brush and helicoidal knives.
In order to allow the shearing device and the brush roller to be adjusted
according to the thickness of the ropes to be sheared, the flat knife and the shaft
with the helicoidal knives are resting in a frame pivoted inside the cylinder, and
for the brush roller another frame is arranged in the like manner.
The free ends'
of such-pivoted frames are connected by means of links to a sliding nut, which is
moved forwards or backwards in radial direction towards the axis of the cylinder,'
by turning the screw spindle passing through the centre of such nut,

I, PIETER MONTAUBAN VAN SWYNDREGT, of the firm of De Wed, Cool & Zoon,
of Kralingen, near Rotterdam, in the kingdom of Holland, Rope Manufacturer, do
hereby declare the nature of my invention for "IMPROVEMENTS IN MACHINES FOR
SHEARING ROPES," 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 improvements in machines for shearing or clipping ropes,
and more especially to such machines as are described in my patent, N° 1405, of
March 16th, A.D. 1883; and the objects of my improvements are; first, to cause
the principal parts of the machine, as described in the said patent, N° 1405 of 1883,
to rotate around their axes, and, simultaneously, around the rope; instead of the
rope being rotated while passing the machine; second, to provide suitable means
for such rotary motion; and third, to adjust the working parts of such machine"
correspondingly with the thickness of the ropes to be sheared.
I attain these objects by the mechanism illustrated in the accompanying drawings,
in which,
Figure 1 is a side elevation, partly in section, of my improved machine; figs 2.
and 3 are cross sections at the lines A B and C D in Fig. 1 respectively. Fig 4 is
a side elevation of a part of the cylinder, wherein the shearing device is enclosed;
Fig 5 and 6 shew details.
Similar letters refer to similar parts throughout the several views.
The shearing or clipping mechanism,-composed of a stationary flat knife a, and
revolving helicoidal knives b, and the brush roller c, of the same shape as they are
described in any said former patent, are enclosed within a cylinder d, through the
centre of which passes the rope to be sheared, and which is turned by a belt or
strap running upon the grooved pulley f, and transmitting the rotary motion of a
pulley driven by hand or machinery. The cylinder d is provided with hollow.
pivots d' for passing the rope, and such pivots, d', are running. in suitable bearings g.
fixed to the frame or stand of the machine.
A fixed disc or pulley h, having a notch or groove in its circumference, is centrally
placed in front of the rotating cylinder d.containing the clipping mechanism and
the revolving brush; an endless strap laid in the groove or notch of said disk h
passes over the slantly placed guiding rollers i to the pulley c¹ of the brush roller c,
and to the pulley b¹ fixed to the shaft b' whereon the helicoidal. knives bare
fastened, thus transmitting the rotary motion of the cylinder d to the said brush c
and helicoidal knives b.
In order to allow the shearing device and the brush, roller o to be adjusted
according to the thickness of the ropes to be sheared, the flat knife a and the
shaft 62 with the helicoidal knives 6 are resting in a frame k pivoted inside the
cylinder d, and for the brush roller c another frame is arranged in the like
manner. The free ends of such pivoted frames / and are connected by means of
links m to a sliding nut n which is moved forwards or backwards in radial
direction towards the axis of the cylinder by turning the screw spindle o passing
through the centre of such nut,

page_text: 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
1. In machines for shearing ropes, the combination of the rotating cylinder d,
with the brush roller c, and the shearing device, substantially as described.
2. In machines for shearing ropes, the combination of the rotating cylinder d,
the brush roller c, and the shearing device with the fixed disk or pulley h, and
rollers i, for guiding the belt or strap laid around the disk h, and the pulleys b',
and c, substantially as set forth.
3. In machines for shearing ropes, the combination of the frames 1, and k, with,
the links
m, the nut n, and the screw spindle o, substantially as and for the purpose
specified.
