An Improvement or Improvements in Putting Belts or Bands on
Pulleys.
I JOSEPH HARKNESS of No. 5 Woodville Place Holyhead Road Handsworth in
the County of Stafford Mechanic do hereby declare the nature of this Invention to
be as follows :-
My invention has for its object to supersede the ordinary method of putting belts
or bands on pulleys and thereby to avoid the risk of accident to the operator which
is inseparable from the ordinary or hand method of putting belts or bands on pulleys.
By the use of my invention not only is the risk of accident to the operator avoided
but the belt or strap is guided to its proper position on the pulley with an ease and
certainty unattainable by the ordinary or hand method.
After the belt or band has been thrown off its pulley and when the pulley is at
rest 1 place the ascending side of the belt against the ascending side of the rim of
the pulley and I pass a light strap around the rim of the pulley and the belt so as to
strap the belt to the ascending side of the pulley in the position which the strapped
part of the belt should occupy when the pulley is in motion. The strap by which the
strapping of the belt to the pulley is effected is furnished with a buckle of the peculiar
construction hereinafter described whereby by the pulling of a cord or chain the bar
of the buckle can be withdrawn and the tongue of the buckle thereby liberated from
the hole in the strap. The unbuckling of the strap detaches it from the pulley and
belt and the strap falls from the pulley.
The buckle by which the belt is strapped to the pulley is made as follows. Instead
of making the bar of the buckle against which the tongue bears fixed as usual I make
the said bar separate and fix it temporarily in position by passing it through holes in
the sides of the buckle frame or by making the side of the buckle hook shaped. To
one end of the bar of the buckle I attach a cord or chain. When the strap having
the buckle described is in use the tongue of the buckle bearing against the detachable
bar holds it in place but by the pulling of the cord or chain the bar is withdrawn and
the strap is liberated.
My invention is used as follows:-The belt is strapped to the ascending side of the
stationary pulley in the manner herein before explained. When the pulley is about
to be put into motion the attendant takes hold of the cord or chain attached to the
end of the buckle bar and as soon as the pulley has turned so far that the strapped
part of the belt. has passed the highest point which it can attain the attendant pulls
the cord or chain and detaches the buckle bar. The strap and buckle fall and the
belt which had been fixed until it had passed its highest point is now free and in
position on its pulley.

An Improvement or Improvements in Putting Belts or Bands on
Pulleys.
I JOSEPH HARKNESS of No. 5 Woodville Place, Holyhead Road Handsworth in
the County of Stafford Mechanic do hereby declare the nature of my invention and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
My invention has for its object to supersede the ordinary method of putting belts,
or bands on pulleys and thereby to avoid the risk of accident to the operator which is.

page_text: inseparable from the ordinary or hand method of putting belts or bands on pulleys.
By the use of my invention not only is the risk of accident to the operator avoided
but the belt or strap is guided to its proper position on the pulley with an ease and
certainty unattainable by the ordinary or hand method.
After the belt or band has been thrown off its pulley and when the pulley is at
rest 1 place the ascending side of the belt against the ascending side of the rim of the
pulley and I pass a light strap around the rim of the pulley and the belt so as to strap
the belt to the ascending side of the pulley in the position which the strapped part of
the belt should occupy when the pulley is in motion. The strap by which the strapping
of the belt to the pulley is effected is furnished with a buckle of the peculiar construc-
tion hereinafter described whereby by the pulling of a cord or chain the bar of the
buckle can be withdrawn and the tongue of the buckle thereby liberated from the
hole in the strap. The unbuckling of the strap detaches it from the pulley and belt
and the strap falls from the pulley.
The buckle by which the belt is strapped to the pulley is made as follows. Instead
of making the bar of the buckle against which the tongue bears fixed as usual I make
the said bar separate and fix it temporarily in position by passing it through the sides
of the buckle frame which are hook shaped. To one end of the bar of the bucklo
I attach a cord or chain. When the strap having the buckle described is in use the
tongue of the buckle bearing against the detachable bar holds it in place but by the
pulling of the cord or chain the bar is withdrawn and the strap is liberated.
My invention is used as follows:-The belt is strapped to the ascending side of the
stationary pulley in the manner herein before explained. When the pulley is about
to be put into motion the attendant takes hold of the cord or chain attached to the
end of the buckle bar and as soon as the pulley has turned so far that the strapped
part of the belt has passed the highest point which it can attain the attendant pulls
the cord or chain and detaches the buckle bar. The strap and buckle fall and the
belt which had been fixed until it had passed its highest point is now free and in
position on its pulley.
Figure 1 of the accompanying Drawing represents in perspective a belt or band
in the act of being put on a pulley by the use of my invention and Figure 2 represents
in perspective the opposite side of the pulley after the belt or band has been put on
the pulley and the strap by which the belt was strapped to the pulley released;
Figure 3 represents in side elevation and Figure 4 in plan, drawn to a larger scale,
the strap and appliances connected therewith by which the band is strapped to and
released from the pulley, the ends of the strap being represented fastened by the
buckle, and Figure 5 represents a plan of the same after the strap has been unfastened
by the withdrawal of the detachable bar of the buckle.
The same letters of reference indicate the same parts in the several Figures of the
Drawing.
The light strap by which the belt or band is strapped to the pulley is marked a and
the buckle fixed to one end of the said strap is marked bbb3; 6b being the sido
plates and the tongue of the buckle. The side plates bare hooked at 63 for
receiving the detachable bar c of the buckle, the said bar c being connected by the
chain d to the buckle end of the strap a the end of the chain d being provided with
a corde of such a length as to be within reach of the attendant for withdrawing the
detachable bar. For example when the band is to be put on an overhead pulley the
length of the cord e when the strap a is fixed to the pulley should be sufficient to
nearly reach the ground or floor.
When the detachable bar c is engaged with the hooked parts 68 68 of the buckle
and the perforated end of the strap a has been engaged with the tongue & the latter
bears on the bar c and the two ends of the strap are buckled or fastened together as
represented in Figures 1, 3 and 4. In order to unfasten or disconnect the ends of
the strap a the detachable bar c is withdrawn from the buckle frame by pulling the
chain and cord d, e; the bearing for the buckle tongue 6 being thus removed the
perforated end the strap readily rises from off the said buckle tongue and the two
ends of the strap are disconnected as illustrated in Figures 2 and 5.

page_text: In putting the belt on the pulley I proceed in the manner illustrated in Figure 1,
that is to say, the pulley being stationary 1 strap the belt or band g to the
ascending side of the said pulley by means of the light strap a and appliances
herein before described, the cord e in connection with the detachable bar c being
passed over to the descending side of the pulley at which side it is held by the
attendant.
The pulley being set in motion und rotating in the direction of the arrows, the
strapped belt or band g is carried with it on its ascending side and as soon as the
pulley has turned so far that the strapped part of the belt 9 has passed the highest
point which it can attain the attendant pulls the chain and cord de thereby with-
drawing the bar c of the buckle. The ends of the strap a being thus unfastened the
said strap falls from the pulley as illustrated in Figure 2. The belt g which had
been fixed on the pulley until it had passed its highest point is now free and in
position on the said pulley as represented in the said Figure 2.
Although I have represented in the accompanying Drawing the ends of the strap
by which the band is strapped to the pulley fastened by a buckle having a detachable
bar by the withdrawal of which the ends of the strap can be rapidly unfastened at
the proper time for releasing the band from the pulley yet other equivalent mechanical
arrangements for fastening and releasing the ends of the strap may be employed with
the same or nearly the same effect. For example the ends of the strap may be passed
through and fastened to the frame of a lever buckle or grip of the kind commonly
used for fastening braces or other equivalent fastening, the said lever grip or lever
buckle or fastening being taken out of action by pulling the chain or cord attached
to the lever grip or holding part of the fastening. I prefer however to use the
arrangement of parts herein before described and represented in the accompanying
Drawing which arrangement I have found to answer well in practice.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed 1 declare that I claim
as my invention :-
The method of and appliances for putting belts or bands on pulleys herein before
described and illustrated in the accompanying Drawing; that is to say, temporarily
fixing the belt or band against the ascending side of the stationary pulley by the use
of a strap so that on the rotating of the pulley the strapped part of the belt or band
is carried with it and placed on the pulley, the ends of the said strap being so buckled
or fastened together that by the use of a detachable bar in connection with the
buckle frame or by a gripping lover or other equivalent fastening operated by the
attendant the ends of the strap can be readily unfastened or released when the belt
or band strapped to the pulley has reached its highest point so as thereby
to release the said belt or band from the pulley substantially as described and
illustrated.
