PROVISIONAL SPECIFICATION.
An Improved Construction of Winding Apparatus for Hauling or
Raising and Lowering Objects.
We, ADRIEN HALLIER and EUGENE LETELLIER, of No. 16 Rue Drouot,
Paris, France, Contractors, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to an improved construction of winding apparatus for
hauling or raising and lowering objects, more particularly applicable for the move-
ment of vehicles on inclines; it consists mainly of an arrangement of pullies placed
obliquely to the traction or hauling pullies and which are intended to enable a
sufficient amount of friction to be exercised upon the hauling cable or chain to
admit of the suppression of the drum on which the cable or chain is wound, in con-
structions in actual use.
For this purpose, the main horizontal shaft of the apparatus, which is driven by
suitable gearing from a motor engine or transmission shaft, carries at each end a
grooved winding pulley round which passes the hauling cable or chain, so as to be
alternately wound up by the one pulley and paid out by the other one.
Above these pullies are mounted two other grooved pullies placed in line with
each other and situated obliquely relatively to the winding pullies, in such manner
that the outer part of the periphery of the one oblique pulley is situated perpen-
dicularly or nearly so over the front part of the periphery of the one winding
pulley, while the outer part of the periphery of the other oblique pulley is situated
perpendicularly or nearly so over the rear part of the periphery of the other winding
pulley.
The hauling rope or chain passing up from the vehicle, cage, or other object,
is passed one or more times round the periphery of the first named winding pulley,
and is then led up and over the first named oblique pulley, from which it is then
led over the second oblique pulley, and from the latter it is passed down to the rear
side of the second winding pulley and after being coiled one or more times round
the latter, it passes away down the incline or shaft, to the other vehicle, cage or
other object.
By thus enabling the hauling rope or chain to be coiled one or more times
round the winding pullies, an amply sufficient frictional resistance to prevent
slipping is obtained, no matter how heavy the load may be.
In order to prevent as much as possible any frictional contact between the coils
of rope or chain on the winding pullies as it passes up to the oblique pullies, the
former are so placed relatively to the guide pullies on the two roads of the incline,
that the rope or chain passes from the winding pullies at a slight outward angle to
the guide pullies while they pass at a slight inward angle from the winding pullies
up to the oblique pullies, whereby the coils on the former are kept apart from each
other at the point where the rope or chain passes up to the oblique pullies.

An Improved Construction of Winding Apparatus for Hauling or
Raising and Lowering Objects.
We, ADRIEN HALLIER, and EUGENE LETELLIER, of No. 16 Rue Drouot,
Paris, France, Contractors, do hereby declare the nature of this invention and in
DQ973

page_text: what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
Our invention relates to an improved construction of winding apparatus for
hauling or raising and lowering objects, more particularly applicable for the move-
ment of vehicles on inclines; it consists mainly of an arrangement of pullies placed
obliquely to the traction or hauling pullies and which are intended to enable a
sufficient amount of friction to be exercised upon the hauling cable or chain to
admit of the suppression of the drum on which the cable or chain is wound in con-
structions in actual use.
The construction for this purpose will be readily understood on reference to the
accompanying drawing, in which
Fig. 1 shews an elevation, and Fig. 2 a plan.
Only those parts of the apparatus are shown that are necessary for explaining
the nature of the invention the other parts being of ordinary construction.
Rotary motion is transmitted in the ordinary manner to the shaft A and by the
pinion B on this shaft to the wheel C fixed on the shaft D on the ends of which
are fixed the pullies E F, round which pass respectively the ascending and
descending parts of the hauling chain or rope, which pass parallel to each along an
inclined railway or along the shaft of a lift.
Above the said pullies are arranged oblique bearers G between which are placed
two pullies H L so arranged that their grooves correspond approximately to those
of the pullies EF. The chain or rope coming from the carriage on the incline is
first coiled one or more times round the pulley E: it then passes up and over
pullies Hand L and descends from the latter again to pulley F round which
it is also passed one or more times, and then passes to the other carriage on
the incline.
->
By thus enabling the hauling rope or chain to be coiled one or more times
around the winding pullies E F, amply sufficient frictional resistance to slipping
is obtained, no matter how heavy the load may be. In order to prevent as
much as possible any frictional contact between the coils of rope or chain on
the pullies EF as it passes up to and down from the pullies H L, the pullies E F
are fixed at a slightly less distance apart from centre line to centre line, than the
distances between the centre lines of the two lines of rails, so that the rope or chain
passes at a slight outward angle from the hauling pullies to the vehicles, and are
thus quite clear of the parts of the rope or chain passing up to the pullies H L,
which parts may also be slightly inclined in the opposite direction, so as to increase
the said distance.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is :-
:-
In winding or hauling apparatus for inclined railways and similar purposes, the
combination with the winding or hauling pullies on which the hauling chain or rope
is coiled one or more times of two guide pullies placed obliquely to the plane of the
hauling pullies, over which guide pullies the chain or rope is made to pass on its
way from the one hauling pulley to the other, substantially as described with
reference to the drawings.
