Improvements in or relating to Rope or Band Driving Gear.
I, HENRY CALDWELL of 9 West Bank Street, Hinsford, Atherton near
Manchester, in the County of Lancaster, Smith, do hereby declare the nature of
my said invention to be as follows:-
:-
This invention consists of improvements in or relating to rope or band driving gear
and has for its object that of removing a band or rope from a fast driving
pulley to a loose pulley and vice-versa for the purpose of stopping and driving
machinery. This I effect by constructing each pulley with an outside cylindrical
side flange and the inside with toothed or serrated flanges, the latter in both
pulleys being disposed against or in close proximity to each other. The band
or rope is slid from one pulley to the other by a suitable fork. As the band or
rope is travelling-to rotate the shaft on which it is secured--the fork is moved,
thus placing the former in contact with the toothed or serrated flanges which
lifts or passes the band or rope into the groove on the loose pulley to stop the
machine to which it may be applied. To enable the rope or band to be removed
from or replaced on from the pulleys one of the flanges of the upper or other
driving pulley is provided with concaved or other indentations sufficiently large
to receive the diameter of the rope or band.

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:-

DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of my invention for improvements in or relating to
rope or band driving gear-Fig. 2 an end elevation of Fig. 1-Fig. 3 an enlarged
end view of my improved pulley-Fig. 4 a front view looking on left hand side
of Fig. 3 Fig. 5 a front view looking on right hand side of Fig. 3-Fig. 6 a
plan of fork arrangement for removing rope or band from fast pulley to loose
pulley and vice-versa.
A is a fast hand or rope driving pulley; B driving shaft; C fast pulley; E out-
side flanges; H inside toothed or serrated flanges: I loose pulley; O fast pulley;
K driven shaft; L band or rone, and M. the fork arrangement for moving the
band or rope from the pulley I to the pulley and vice-versa.
Each pulley is provided with a side flange E and a toothed or serrated flange H.
In placing two of these pulleys together side by side, as shown in Fig. 2, the side
flanges E form the outside flanges, and the toothed or serrated flanges H the
inside ones.
The flanges E are provided with four (or more or less) indenta-
tions P. and the flanges H with eight (or more or less) indentations R as shown
in the drawings. The flanges H are always constructed or provided with double
the number of indentations to those in the flanges E, the number being as desired
or required according to the size or diameter of the pulleys. The band or rope L
is moved or slid from the fast pulley O to the loose pulley I and vice-versa by the
fork arrangement consisting of the pulleys S mounted on the centres T secured
to the sliding bar M mounted in the fixing or fixings W secured to the machine
being operated or to any other convenient position according to what the driving
gear is intended to actuate.
This invention operates in the following manner:-When the band or rope L
is intended to rotate the shaft K by means of the fast pulley. O mounted thereon
the fork-bar M carrying the centres T is moved in the direction indicated by
the () arrow, by which action the band or rope L is placed in contact
with the toothed or serrated flanges H which lifts or passes the band or rope L
into the groove of the pulley 0, by which the shaft K will be rotated, thus
actuating the machine or its equivalent it may be attached to. The indenta-4
tions P and R are constructed of varying sizes according to the diameter of the
band or rope employed. In case the shaft B is driven from a counter or other
shaft the fast pulley C may be employed, the latter being operated by a rope or
band from any convenient position.
If desired this invention may be employed for driving either up or down, or 4
on an angle, or horizontally, or diagonally as desired or required.
If desired the loose pulley I may be dispensed with and the fast pulleys A and O
employed alone when the driving is constant.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I 5
claim is:-
:-
1. The construction, combination and arrangement of the fast and loose
pulleys composing my improvements in or relating to rope or band driving gear,
the said pulleys being provided with indentations, and operating either un.

page_text: down, horizontally, or diagonally as desired or required, substantially as herein-
before described and as illustrated in the annexed drawings.
2. The use and consideration of the band or rope pulleys provided with
indentations substantially as described for the purposes set forth.
