Improvements in Apparatus for Placing Belts onto Pullies.
I, GEORGE HENRY HUGHES, of 99, Warwick Street, Free Holl, Oldham, in the
County of Lancashire, 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 :-
The object of my invention is to provide means whereby belts can be placed onto
pullies more readily and selfactingly, either from the bottom or the top and
which are capable of adjustment so as to suit various diameter of pullies and can
be used on each side thereof.
And in order that my invention. may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Figs. 1. & 3. are side elevations and Figs. 2. & 4. back views of my improved
apparatus for placing belts onto pullies applied.
Referring to the Figs. generally my invention consists, in the use of a radial arm or
arms a capable of being lengthened and shortened, placed on the shaft against the
side of the pulley furnished between the same with one or more anti-friction
rollers d, din conjunction with a slip or guide e, such radial arın or arms a being
operated either by a handle ff' or chain.
In carrying out my invention, Figs. 1. & 2. represents a portable apparatus for
placing belts onto pullies constructed according to my invention and showing it applied
to put on the belt from below.
For placing narrow belts the apparatus may be formed with one radial arm a only
and for broad belts, preferably with two radial arms a suitably connected together at
convenient distance apart from each other, by means of rods h, & h².
The inner ends of the arm or arms a form an open bearing a' and serve to receive
the shaft and are provided with an anti-friction roller d', the outer end or ends a²
being also furnished with anti-friction rollers d, on which the belt A, on being placed
onto the pulley c runs.
The inner end or ends of the radial arm or arms a are formed respectively with a
shank a which is arranged to slide and be adjusted on the outer end or ends a² of the
arm or arms a by means of thumb-screws i so as to lengthen the arm or arms a radially
according to the diameter of the pulley, onto which the belt is to be placed.
At the back of the anti-friction roller or rollers d, is fixed on the rod h, to depend
therefrom, the slip or guide e, the lower end of which is V shaped and serves to conduct
the belt onto the pulley c.
To the rod is also secured a handloff, by means of which the apparatus is
placed onto the shaft against the side of the pulley e and a collar m, fixed on the
shaft and by means of which it is operated.
This handle is formed hollow and in two parts which are connected together
by means of a hinge-joint k, which latter can be broken, as shown in the drawing, for
the purpose of facilitating the manipulation of the apparatus, by withdrawing a
bolt , which passes through the respective ends and can be retained in position, by
means of thumb-screws .
To facilitate the use of the apparatus for placing belts onto pallies from above, 1
employ on the rods & h², at the back of the apparatus, a segment i, on which the
handle is permitted to slide & can be fixed in a position opposite to that indicated
in the drawing, by means of the thumb-screw, the inner ends of the arm or arms a
being reversed for the said purpose.
In order to prevent the apparatus from leaving the shaft b, I may employ a rod, the
lower end of which is hinged to the handle part f¹, and the upper end of which is fork

page_text: like and bears against a rod fixed in the lower jaw of the inner end of the radial arm or
arms a, which fork, on the handle part being raised slides across the shaft 6, thus locking
the apparatus thereto; or I preferably employ a double acting locking lever / pivoted
to the arm or arms a, one end of which locking lever l, is formed with two claws l',
which by means of a chain attached to the opposite end 12 of the lever can be
brought to bear against the shaft b either in placing the belt A onto the pulley c from
below or above, and retained in its position by placing the chain 13 onto the hook l* on
the hinge k.
The working of the apparatus is as follows:-
The apparatus by means of the handle ƒ ƒ (which in the first instance is locked) is
placed between the belt A and onto the shaft b, between a collar m fixed onto the
latter, and the side of the pulley c.
The hinge-joint of the handle, f' is then broken, by withdrawing the bolt k', the
belt A running on the anti-friction roller or rollers d, d and bearing against one side
of the shaped slip or guide e, is then caused by the latter and the rotation of the
pulley c to be removed from the apparatus onto the pulley c, on the apparatus, by
means of the handle f,, being moved radially in the direction of the arrow.
Figs. 3. & 4. illustrate a stationary apparatus for placing belts onto pullies
constructed in accordance with my improvements.
The radial arm or arms a (which may be also formed, to be lengthened if deemed
necessary) are formed on a boss a' which is fitted onto the shaft & between the pulley c
and the collar m.
The outer ends of the arm or arms a are respectively provided with one or more
anti-friction rollers d in conjunction with a V shaped slip or guide e, suitably attached
to the apparatus.
The opposite side of the boss a' is formed with a lever n and provided with a rod g
or chain, by means of which the apparatus is operated and the placing of the belt
effected similarly as is the case in the portable apparatus.
When desired to place the belt from above onto the pulley c, the apparatus, by means
of the rod g or chain, is simply turned on the shaft 6 in the opposite direction, than
what is required when placing it from below.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
"In apparatus for placing belts onto pullies."
1st. The general arrangement and combination of parts, operated substantially as
and for the purpose specified.
2nd. Formning the arm or arms a in two parts a¹ & a³, so as to be radialy adjustable
and capable of being lengthened and shortened to suit various diameter of pullies,
substantially as set forth.
3rd. The use and application of the slip or guide e, substantially as and for the
purpose specified.
4th. The application to the handle of the apparatus of the hinge k and bolt k¹,
substantially as and for the purpose specified.
5th. The use of a radial arm or arms a, furnished at its free end or between the ends
thereof with anti-friction roller or rollers d d', in conjunction with a slip or guide e,
operated by means of a handle f, f¹, or a rod 9, substantially as and for the purpose
specified.
