Improved Apparatus for "Putting-on" the Driving Straps or Belts of
Revolving Pulleys.
We, HAROLD CLIFF, of 35, Coppice Street, Assistant Secretary, and TRAVIS
BURTON, of 34, Rutland Street, Draughtsman both of Oldham, in the County of
Lancaster, do hereby declare the nature of this invention to be as follows:-
ور
This invention relates to the construction of improved apparatus for "putting-
on the driving straps or belts on pulleys whilst revolving, thus avoiding all
danger of accidents.
The improved apparatus consists principally of a segmental pulley or guide
which is mounted loosely on the shafting alongside of the driving pulley, the
central boss of the said segmental pulley being held close to that of the driving
pulley, by means of a collar. The segmental pulley or guide is preferably made
about one quarter of the circle, the circumferential part of the same being pre-
ferably of the same diameter as the driving pulley, and their edges lying close
together, but in some cases the circumferential part or rim of the segmental pulley
may be of slightly larger diameter so as to overlap the circumference of the driv-
ing pulley. The circumferential part or rim of the guide pulley is connected to its
boss by a segmental plate or web, and it is tapered or inclined at its outer edge,
i.e., the edge furthest from the driving pulley alongside which the apparatus is
placed, and this inclined edge is provided with a flange projecting outwards.
The taper must be such that at the widest part the rim of the segmental guide
is at least the same width as the strap or belt which it is desired to put on, and
at the narrowest part it must be less than the width of the strap.
When the strap or belt is loose or off the driving pulley the segmental guide
hangs down out of the way but when it is required to be put on the revolving
Iriving pulley the workman, by means of a rod or other suitable instrument raises
p the segmental guide until the wide part or leading edge of its rim comes against
he inside of the strap. The strap will then tend to lie along the rim of the
egmental guide in such a manner that as the segmental guide is further raised
he portion of the width of the strap which overlays the tapering rim will come
contact with the surface of the driving pulley.
This will cause the segmental guide to commence revolving, and as it revolves
he inclined flange on the segmental guide will act against the edge of the strap
belt and push it sideways onto the revolving driving pulley, and when the
gmental guide has performed this work it will fall away from the strap and hang
osely on the shaft as before.

We, HAROLD CLIFF, of 35, Coppice Street, Assistant Secretary, and TRAVIS
BURTON, of 34, Rutland Street, Draughtsman both of Oldham, in the County of
Lancaster, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement -
"
This invention relates to the construction of improved apparatus for "putting-
on the driving straps or belts on pulleys whilst revolving, thus avoiding all
danger of accidents.
Our improved apparatus will be readily understood on reference to the sheet
of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a side elevation, Fig. 2 an edge view, and Fig. 3 a
plan view of a driving pulley with our improved apparatus shown as applied
thereto, a being the shaft, b the pulley and the driving belt, these figs. showing
the position of the apparatus when the belt c is off the pulley b and hanging loosely
over the shaft a.
Figs. 4, 5 and 6 are similar views showing the action of the apparatus when
"putting-on" the driving belt.
The improved apparatus consists principally of a segmental pulley or guide d
which is mounted loosely on the shaft a alongside of the driving pulley b the
central boss of the said segmental pulley & being held close to that of the driving
pulley by means of a collar e.
The segmental pulley or guide d is preferably made about one quarter of the
circle, the circumferential part of the same being preferably of the same diameter
as the driving pulley b, and their edges lying close together.
The circumferential part or rim of the guide pulley d is connected to its boss
by a segmental plate or web, and it is tapered or inclined at its outer edge i.e.
the edge furthest from the driving pulley 6 alongside which the apparatus is
placed, this inclined edge being provided with a flange f projecting outwards beyond
the circumferential part.
The taper must be such that at the widest part the rim of the segmental guide d
is, at least, the same width as the strap c which it is required to "put-on" and
at the narrowest part it must be less than the width of the said strap.
When the strap or belt c is loose or off the driving pulley, the segmental guide d
hangs down out of the way (see Figs. 1, 2 and 3) but when it is required to be
put on the revolving driving pulley b the workman, by means of a forked rod
or other suitable instrument g applied to the projection h (see Fig. 4) raises up
the segmental guide d until the wide part or leading edge of its rim comes against
the inside of the strap c. The strap will then tend to lie along the rim of the
segmental guide in such a manner that as the said guide is further raised the
portion of the strap which overlays the tapering rim will come in contact with the
driving pulley b.
This will cause the segmental guide d to commence revolving, and as it revolves
the inclined flange f, on such guide will act against the edge of the strap or
belt c and push it sideways onto the revolving driving pulley (see Figs. 4, 5
and 6) and when the said segmental guide has performed its work it will fall
away from the strap and hang loosely on the shaft as before.

page_text: 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;-
The improved apparatus for "
pulleys consisting of a segmental pulley or guide mounted loosely upon the shaft
putting-on" the driving straps of revolving
close to the pulley and provided with an inclined projecting flange which as the
said segmental pulley or guide is raised up acts against the edge of the driving
strap and puts it onto the driving pulley substantially as hereinbefore described
and illustrated by the drawings annexed.
