PROVISIONAL
ATION.
Improvements in the Construction of Friction Clutches for
Driving Shafts, Wheels, Pulleys, or other Rotating Parts of
Machinery.
I, JOHN WILD, of Falcon Iron Works, Oldham, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows :-
In my improved clutch I make an annular carrier in which a number of shoes
are fitted which shoes may be forced ontward by means of screws or inclined
planes actuated by levers so as to come in close contact with a suitable preparation
secured upon the wheel pulley or other object with which it is desired connection
shall be made.
In order to compensate for the wear that may occur in the shoes and their con-
nections the said screws may be fitted with separate nuts which may be secured to
the carrier in any convenient way and which may be revolved separately and
independently so as to force the screws together with their shoes further outwards
as wear takes place.
Or the shoes themselves may form the nuts and when it is desired to take up the
wear the levers may be loosened and the screws (which are carried by suitable
bearings) revolved, so as to force the shoes outwards as far as desired when the
levers may be refixed upon the screws.
COMPLETE SPECIFICATION.
Improvements in the Construction of Friction Clutches for
Driving Shafts, Wheels, Pulleys, or other Rotating Parts of
Machinery.
I, JOHN WILD, of Falcon Iron Works, Oldham, in the County of Lancaster,
Engineer, 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 :-
In my improved clutch I make an annular carrier A A A in which any number
of shoes B B B are fitted which shoes may be forced outward by means of
screws CCC or inclined planes actuated by levers D D D (which may be con-
nected to the grooved collar or plate E as shown) so as to come in close contact
with a suitably prepared surface F secured upon or forming part of the wheel
pulley or other object with which it is desired connection shall be made.
In order to compensate for the wear that may occur in the shoes B B B and
their connections the said screws C C C are fitted with separate nuts G G G
which may be secured to the annular carrier by set screws H H H or in any
other convenient way.
As will be seen the nuts G G G may after loosing the
set screws HHH be turned separately and independently so as to force the
screws CCC together with their shoes B B B further outward as wear takes
place or the shoes themselves may form the nuts so that when the screws are
turned by means of the levers the shoes will be forced outward so as to come in
contact with the preparation on the wheel pulley or other object with which it
is desired connection shall be made and the wear may be taken up by loosing the
lever and then turning the screw so as to put the shoe in the desired position and
then refixing the lever.
It must be distinctly understood however that I do not confine myself to this
particular arrangement. Other arrangements may be made to suit various require-
ments

page_text: 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
claim is :-
:-
1. A friction clutch having an annular carrier titted with shoes substantially and
for the purpose described and illustrated by the accompanying drawings.
2. A friction clutch having an annular carrier fitted with shoes and loose nuts
which may be secured by set screws substantially and for the purpose described and
illustrated by the accompanying drawings.
3. A friction clutch having an annular carrier fitted with loose shoes and nuts
secured by set screws or other suitable means and screws actuated by levers
substantially and for the purpose described and illustrated by the accompanying
drawings.
