COMPLETE SPECIFICATION.
A Machine or Apparatus for Manufacturing Ropes of Trapezoidal
Formation in Cross Section,
I, FRANZ EDWARD ALBERT GÜNTHER, of 16 and 17, Woorth, Halberstadt, in the
Kingdom of Prussia, German Empire, Merchant, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement;
This invention relates to a machine or apparatus for twisting or platting together
a number of strands for the manufacture of ropes of trapezoidal formation in cross
section, the object of such a rope being to render the same more particularly
adapted for use in connection with pulleys or wheels having a groove or grooves
of like or similar formation, formed therein, so that the said ropes when used
for driving the said pulleys or wheels may not twist or turn therein.
In order that my said invention may be fully understood, I hereinafter refer
to the accompanying drawings of which:-
Fig. 1 is a sectional elevation on line XX of Fig. 3 showing the toothed wheel
gearing.
Fig. 2 is a side elevation partly in section showing a bobbin in connection with
the toothed wheel gearing.
Fig. 3 is a section on line yy of Fig. 1, showing the guide plate in dotted
lines.
Fig. 4 is a plan representing the guide plate.
Fig. 5 is a section of a rope produced by the said machine or apparatus.
My invention consists of a guide plate A, in which is provided two circular
grooves B and B of a predetermined diameter, and two like grooves CC also
of predetermined diameter, the circumferential diameters of those CC being
preferably one third or thereabouts less than those B and B', and so arranged
that CC and B B¹ communicate with each other, while C communicates with B
and Cwith B', and within the said groove is placed the stems or spindles D of
six bobbins E, each of which said bobbins carries one of the six strands F of which
the rope is to be composed, and each of the said strands may consist of any number
of minor strands or cords F1 (Fig. 5).
The stems I) of the bobbins E extend below the said grooves in A, and engage
with semi-circular notches a in horizontal discs H and H¹, mounted upon vertical
spindles and J' in the centre of the grooves B and B¹, and like but smaller
discs K and K' mounted upon vertical spindles L and L' in the centre of the
grooves C and C, the said spindles being rotated by toothed wheels M and M'
(Fig. 1) fixed thereon and actuated by other toothed gearing, (not shewn) operated
by any available power. Upon the spindles J and J¹ are mounted sleeves N
and N1, and upon the spindles L and L' are like sleeves 0 and O¹, and upon the
lower ends of N and N are mounted toothed wheels P (Fig. 1) actuated by other
toothed wheels (not shewn) while upon the upper ends of N and N are mounted
toothed wheels R, with which engage pinion wheels G, mounted loosely upon the
stems 1), of certain of the bobbins E. In like manner upon the lower ends of the
E

page_text: sleeves 001 are mounted toothed wheels S in gear with P', while upon the upper
ends of OO are mounted toothed wheels R¹ (Fig. 1) which gear with pinions G
upon the stems D of certain others of the bobbins E.
In practice, the toothed wheels R R and the discs HH', K and K' rotate in the
direction of the arrows in Fig. 3, but not necessarily at the same speed, the speed of
these being such that the stems D, indicated by 1, 3, and 5, (Fig. 3) are caused to
traverse the grooves in the paths indicated by the double headed arrows Fig. 4,
and those indicated by 2, 4 and 6 (Fig. 3) are caused to traverse the grooves in the
paths indicated by the single headed arrows in Fig. 4, the semicircular notches a
always occurring, relatively to each other, in such a way as to throw the bobbins
into these paths, so that each bobbin in traversing its allotted path travels over a
larger area at one side of the machine than at the other, the strands upon the
said bobbins being thereby platted or twisted together, or in other words pass
round and about, and eventually become twisted or platted with each other, and
form a rope of trapezoidal formation in cross section, after the manner indicated
by Fig. 5.
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). The manufacture of ropes of trapezoidal formation in cross section, and the
here described machine or apparatus for producing the same, connected, com-
bined and operating substantially as herein set forth and shewn.
(2). The herein described machine or apparatus for producing twisted or platted
ropes of trapezoidal formation in cross section, the characteristic features of the
said machine consisting of two pairs of discs HH and KK¹, the former pair
being larger in diameter than the latter, whereby the bobbins E are caused to
traverse a larger path upon one side of the machine than upon the other substan-
tially as and for the purposes set forth.
(3) The herein described machine or apparatus for producing ropes of trape-
zoidal formation in cross section, consisting of the combination of a guide plate A,
in which is provided circular grooves BBC and C₁ forming guides for bobbins E,
each carrying a strand F, the said bobbins being adapted to engage with notches a
in discs if HK and K¹ mounted upon spindles JJ L and L', the said spindles
carrying sleeves N' N¹ O and 01 upon which are mounted toothed wheels R R¹,
in gear with pinions G, upon the stems D) of the said bobbins, the said
bobbins being caused by suitable gearing to traverse the said grooves in the
directions indicated by the arrows in Fig. 4, substantially as herein set forth and
shewn.
