Prussia, Germany, for an Invention of "IMPROVED APPARATUS FOR STOPPING,
NIPPING OR HOLDING CABLES OR ROPES

PROVISIONAL SPECIFICATION left by the said Franz Carl Guilleaume at
the Office of the Commissioners of Patents on the 7th August 1883.
FRANZ CARL GUILLEAUME of Cologne in the kingdom of Prussia, Germany
"IMPROVED APPARATUS FOR STOPPING, NIPPING OR HOLDING CABLES OR ROPES
"
My invention has reference to apparatus for stopping, nipping or holding cables
or ropes, so as to control their motion when running off a drum or otherwise set in
motion According to my present invention, I construct such apparatus of a fixed
frame having a curved and grooved surface against which is situated the similarly
curved and grooved surface of a loose pulley, both curved surfaces being formed
according to the Archemedian spiral.
The cable or rope being passed through the channel formed by the opposite
grooves of the framing and pulley, it can either be allowed to run freely through
the same, or its motion can be checked to any desired extent by turning the pulley
more or less on its axis in the framing, either by means of a hand lever inserted
into pockets or recesses on the pulley, or by a capstan wheel, or by gearing. The
axis of the pulley is by preference formed as a large hollow boss passing through a
corresponding hollow boss on the framing and secured therein by a ring shaped disc
screwed to its outer end. The two ends of the curved and grooved surface of the
framing are formed with an outward curvature so as to lead the rope easily to and
from the before mentioned channel.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Franz Carl Guilleaume in the Patent Office on the 31st January

page_text: motion. According to my present invention, I construct such apparatus of a fixed
frame having a curved and grooved surface, against which is situated the similarly
. curved and grooved surface of a loose pulley, both curved surfaces being formed
according to the Archemedian spiral.
The cable or rope being passed through the channel formed by the opposite &
grooves of the framing, and pulley, it can either be allowed to run freely through
the same, or its motion can be checked to any desired extent by turning the pulley
more or less on its axis in the framing, either by means of a hand lever inserted
into pockets or recesses on the pulley, or by a capstan wheel or by gearing. The
axis of the pulley is by preference formed as a large hollow boss passing through a 1
corresponding hollow boss on the framing, and secured therein by a ring shaped disc
screwed to its outer end. The two ends of the curved and grooved surface of the
framing are formed with an outward curvature, so as to lead the rope easily to and
from the before-mentioned channel
DESCRIPTION OF THE DRAWINGS
Figs. 1, 2 and 3 of the accompanying drawings shew respectively a front view,
a cross section, and a sectional plan of oue form of my above described improved
apparatus for stopping, nipping or holding cables.or ropes, the apparatus being
arranged in a vertical position. The fixed shell or frame A having the curved and
grooved surface-w-carries-in-the-central cylindrical aperture n the hollow boss Z
of the pulley B, which is provided on its periphery with a grooved surface formed-
according to the Archemedian spiral, the grooved surface w of the frame being
_formed with a corresponding spiral curvature, its ends being curved outwards, as
shewn, so as to afford an easy entrance and exit to the rope as it passes to and
from the apparatus. The pulley or drum B has sockets or pockets formed on its
face for the reception of hand levers H by means of which it may be turned in one
direction or the other, whereby the rope passing between the two spiral grooves
will either be allowed to run freely through the same, or be held or uipped with
greater or less force, so as to check or stop the passage of the rope. Fig. 4 shews a
plan of a horizontal arrangement of the apparatus which is otherwise constructed
in precisely the same manner as above described, the parts being indicated by the
same letters of reference.
Having thus described the nature of this invention and in what manner the same
is to be performed, I claim :—
The construction of apparatus for stopping, nipping or holding cables or ropes
wherein the fixed and moveable grooves between which the cable or rope passes,
are formed according to the Archemedian spiral.
In Witness whereof I the said Franz Carl Guilleaume have hereunto set my
hand and seal this twenty second day of January in the year of our Lord one
thousand eight hundred and eighty-four.
