Improvements in
in Rope and Analogous Driving Gear.
I RUDOLF HORNSTEINER of Zizkov, Prague in the Kingdom of Bohemia,
Manufacturer, do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The object of my invention is to construct improved apparatus for rope and
analogous driving gear, having all the pullies which serve for tension and guidance
mounted in or upon one frame, so as to form an independent tension apparatus.
In carrying out my invention I construct suitable frames consisting of one or more
bar or parallel bars, for supporting the bearings of the pulleys, and adjusting their
position thereupon.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings, illustrating my invention, in
which similar letters of reference indicate corresponding parts.
Fig. 1 is a front view; Fig. 2 a side view; Fig. 3 a section on the line II of
Fig. 1, shewing my method of fixing the pulley T in position upon the bar A by means
of the guide D, which grips the bar A, as shown.
Fig. 4 is an elevation and Fig. 5 a section on the line II II of Fig. 4, in which A is,
the bar, D is the guide which is fixed in position upon the bar A, and is held by
bolts bb pressed by spiral springs s; the ends of the bolts b are cut diagonally, so as
to grip the bar A and the position of the guide D is adjustable. The pulley T is fitted
to D in a similar manner to that shown in Fig. 3.
Fig. 6 is an elevation (partly in section) Fig. 7 is a side view, and Fig. 8 is a
section on the line III III of Fig. 6. In these Figures A and B are the supports to
H is a moveable
which the guide D is held by the bolts d d, and spiral springs v. v.
attachment covering a gap which is opened (when necessary) for the insertion of the
rope.

page_text: Fig. 9 is an elevation showing one of my methods of fitting the pulleys E. C. T. to
a vertical frame.
Fig. 10 is an elevation and Fig. 11 a side view, showing another method of
_mounting the pulley T in a frame D.
Fig. 12 is a section, Fig. 13 a plan, partly in section, and Fig. 14 a side view
showing a method of mounting a pulley upon two bars. Fig. 15 shows the method
of mounting two pulleys in a similar frame and Fig. 16 is a sectional elevation of a
single pulley, similarly mounted.
Fig. 18 is an elevation partly in section, Fig. 19 is an end elevation and Fig. 17 is
a section on the line IV IV of Fig. 18. Figs. 20 and 21 are elevations of a.frame
formed of angle iron bars fitted with a guide pulley E and two supporting
pulleys C C¹.
Figs. 22 and 23 are similar views showing the two supporting pulleys C C¹
mounted on the same axle as the guide pulley E.
Fig. 24 is an elevation showing another form of mounting the guide pulleys, the
object being to shorten the length of the frame.
Fig. 25 is an explanatory diagram of the block pulleys shown in Fig. 24 in
horizontal section.
Figs. 26 and 27 are diagrams showing another method of mounting pulleys with an
adjustable and elastic support.
Fig. 28 is a perspective diagram illustrating a method of applying my invention to
a series of driving and transmission pulleys.
The rope or band used in the transmission of power from one pulley to another,
requires a certain constant state of tension. I effect this by means of the pulley T (or
by several of such pulleys) the support D of which is guided upon one or two.(or
between two) vertical bars A and B. Owing to the circumstance that the rope
or band varies in length continually from various causes, counter pulleys CC1 C2 are
fitted to take up the slack. These counter pulleys as well as the guide pulley E., I fit
to the same frame A and B (or simply to A only, as shown in Figs. 1 to 5). The
frame consists, mainly of one or two planed or rough vertical bars; when two are
used they are connected together by straps or bolts at each end. These frames may
be fixed in any locality where required, their speciality being that they support the
ordinary pulleys as well as the tension pulleys.
Both elasticity and adjustability are provided for by bolts and spiral springs as
shown in the several figures.
In figures 17. 18 and 19, the support D is guided between the bars A. f B, being
secured by the bolts d and spiral springs v. The bar is pressed by the springs s and
bolts & against the guide B.
The elastic support may also be obtained by the method shown in Figs. 26 and 27
by means of keys K, which keeps the several parts of the frame together, being
pressed by the spring s in one direction, while the springs and bolts d press them in
the other direction against and upon the guide bars A and B.
I wish it to be understood that the frame need not be exactly vertical, and it may
assume any convenient position; but in this case the slack is taken up by either a
weight or spring.
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 method of mounting the support D carrying the tension pulley or pulleys T
in a single frame of one or two planed or unplaned vertical bar or bars A B carrying
the guide pulley E and the counter pulley or pulleys C, substantially as hereinbefore
described and illustrated by the drawings.
2. The method of mounting the support D carrying the tension pulley or pulleys T
as aforesaid, in combination with pins 6 (Figs. 4 and 5) or keys K or bolts d (Fig. 27)
and springs and substantially as hereinbefore described and illustrated by the
drawings.

page_text: 3. In mounting pulleys as aforesaid, the application and use of the gap and covering
plate H for conveniently inserting and removing the rope, substantially as hereinbefore
described and illustrated by Fig. 6 of the Drawings.
4. The general construction, combination and arrangement of the several and
respective parts together forming my improvements in means and appliances for
adjusting the tension in rope and analogous driving gear, substantially as hereinbefore
described and illustrated by the drawings.
