page_text: LETTERS PATENT to Pieter Montauban von Swyndregt of the firm of
De Wed, Cool & Zoon of Kralingen near Rotterdam, in the Kingdom of
Holland for an Invention of "IMPROVEMENTS IN MACHINES FOR SHEARING
ROPES
"
PROVISIONÁL SPECIFICATION left by the said Pieter Montauban von
Swyndregt at the Office of the Commissioners of Patents on the 16th March
1883.
PIETER MONTAUBAN VON SWYNDREGT of the firm of De Wed. Cool & Zoon of
Kralingen near Rotterdam in the Kingdom of Holland "IMPROVEMENTS IN
MACHINES FOR SHEARING. ROPES
My invention relates to improvements in machines for shearing ropes by which
the fibres of hemp, tow or other material, whereof the rope is made, are cut away
in order to smoothen the surface of the rope.
A
A flat knife is supported at both extremities and one two or more helicoidal
knives are fixed on a rotating shaft in such a manner as to produce the effect of a
pair of scissors or shearing action by the mutual work of the rotating knife or
knives and of the fixed flat one. The latter may be provided with a device for
adjusting its inclination towards the shaft of the rotating knife or knives.
rotating or reciprocating brush serves to comb. the fibres of the rope in a suitable
direction for making them capable of being caught by the blades or knives and to
remove the superfluous fibres or shreds. The brush is advantageously provided
with a mechanism for adjusting it relative to the size of the rope which passes
between adjustable guides to keep it in its proper direction. The rope while
being sheared by the machine is caused to rotate slowly by any suitable means or
devices.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Pieter Montauban von Swyndregt in the Great Seal Patent
Office on the 15th September 1883.
PIETER MONTAUBAN VON SWYNDREGT of the firm of De Wed, Cool & Zoon of
Kralingen near Rotterdam in the Kingdom of Holland " IMPROVEMENTS IN
MACHINES FOR SHEARING ROPES
"
My invention relates to improvements in machines for shearing ropes, by which
the fibres of hemp, tow, or other material, whereof the rope is made, are cut away
in order to smoothen the surface of the rope.

page_text: A flat knife is supported at both extremities, and one, two, or more helicoidal
knives are fixed on a rotating shaft in such a manner as to produce the effect of a
pair of scissors or shearing action by the mutual work of the rotating knife or
knives and of the 'fixed flat one. The latter one may be provided with a device
for adjusting its inclination towards the shaft, of the rotating knife or knives. A
rotating or reciprocating brush serves to comb the fibres of the rope in a suitable
direction for making them capable of being caught by the blades or knives and to
remove the superfluous fibres or shreds. The brush is advantageously provided
with a mechanism for adjusting it relatively to the size of the rope, which passes
between adjustable guides to keep it in its proper direction. The rope while
being sheared by the machine is caused to rotate slowly by any suitable means or
devices.
In order to make my invention more clearly understood I will describe it with
reference to the accompanying Drawing, in which
Figure 1 is a front view partly in section of the machine, Figure 2 is a top view
also partly in section; Figure 3 is a side elevation and Figure 4 a vertical section
of the lower part of the machine illustrating the shape and position of the
knives; Figures 5 and 6 are detailed views of the mechanism for adjusting the
rotating brush.
Similar letters refer to similar parts throughout the several views.
The flat knife a is supported at both extremities of its edge by the frame. The
hand screw a¹ serves to adjust the knife a in any position desired relative to the
revolving surface of the rotating knives and the screws a² keep it therein.. Four
helicoidally curved knives b¹ are fastened to the rotating shaft b.
The rotating brush is fixed to the shaft d³ the bearings d' of which slide in the
notches d² of, the frame. The levers d pivoted at the bolts d serve to adjust
the position of the brush to which effect an immovable ratchet wheel. d' is connected
with the bolt d, a spring pawl or spring pawls attached to the levers d' engage
into the teeth of the wheels d'.
The fingers c which serve to guide the rope passing between them move on the
screw spindle c¹ provided with a right and left handed thread; the ratchet wheel c²
fixed to spindle c¹ keeps in combination with the spring-pawl ³ the spindle in the
required position. The adjustable guiding fingers also may be replaced by discs
provided with perforations of different diameter.
Having thus fully described my invention I wish to Claim and secure by Letters
Patent-
In a machine for shearing ropes the combination of the fixed knife u and the
rotating knives b¹ with the rotating brush & substantially as set forth.
In witness whereof I the said Peter Montauban von Swyndregt have hereunto
set my hand and seal this Ninth day of September in the year of our Lord
One thousand eight hundred and eighty three..
