I, CHARLES WILLIAM BURTON, Junior, of 68, Rue des Marais, Paris, in the
Republic of France, Engineer, do hereby declare the nature of this invention to
be as follows:-
-
This invention relates to a new system of disconnecting friction clutch by the aid
of which a progressive and elastic entrainment is produced in an assured manner
which is applicable to all mechanical appliances.
My invention will be well understood by the following description, by referring
to the specimen drawing annexed in which:
―
Figure 1 represents the device in longitudinal section.
Figure 2 shows the same in transverse section.
In these two figures the same letters of reference designate the same parts as can
be seen in the drawing my system of disconnecting and connecting consists of:—a
boss K keyed on the motive axle of transmission, a ring G arranged within the
interior of the boss K so as to remain loose or be driven by the "throwing into
gear" screws E which are operated by the hand gear D controlled by the levers B
and the movable sleeve A.
A spring H is fixed by one of its extremities to the ring G and the other to a
driving band J adapted to pull upon the external cover L and vice versa.
The putting into gear is effected by means of the pressure exerted by the screws E
on the loose ring G which produce a tractive force upon the spring H, which trans-
mits it to the draw band J of which the special form (different widths) permits
its enrolment upon and makes it act as a brake upon the boss K.
The combined effort of traction and entrainment produces the movement of
rotation of L.
For disconnecting it is only necessary to unscrew the screws E and give liberty
to the ring G.
The same effect of putting into gear is produced as is well understood when the
shaft turns constantly in the casing L.
This latter is designed to receive, an ordinary pulley, a grooved pulley, a cog
wheel or other transmitting device which it is desired can be rendered at will
either loose or fixed.
The same effect is produced when the device is adapted to couple two shafts the
one fixed to the boss K and the other to the casing L.

varied without departing at all from the essence of my invention.

An Improved Disconnecting Friction Clutch.
I, CHARLES WILLIAM BURTON, Junior, of 68, Rue des Marais, Paris, in the
Republic of France, 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:-
This invention relates to a new system of disconnecting and connecting friction
clutches, by the aid of which a progressive and elastic entrainment is produced
in an assured manner which is applicable to all mechanical appliances.
My invention will be well understood by the following description, by referring
to the drawing filed with the Provisional Specification in which:-
Figure 1 represents the device in longitudinal section.
Figure 2 shows the same in transverse section.
In these two figures the same letters of reference designate the same parts.
As can be seen in the drawing my system of disconnecting and connecting,
consists of: -
A grooved boss K, keyed on the motive axle of transmission; a ring G arranged
within the groove of the boss K, so as to remain loose or be driven by the boss,
when forced into frictional contact with it';
The "throwing into gear" screws E, which are operated by the gear D, controlled
by the levers B and the movable sleeve A;
A spring H, fixed by one of its extremities to the ring G, and the other end
is merged into a gripping draw band J, adapted to pull upon the external drum L.
The putting into gear is effected by means of the pressure exerted by the screws E
on the loose ring G, which produces a tractive force upon the spring H, which in
turn transmits it to the draw band J, of which the special form (of varying width)
permits its enrolment upon, and makes it act as a brake band upon, the boss K.
The combined effort of traction and brake band action produces the movement
of rotation of the drum L and the driven part of the shaft to which it is keyed.
For disconnecting, it is only necessary to unscrew the screws E and give liberty
to the ring G.
The same effect of putting into gear is produced, as is well understood, when the
shaft turns loosely in the drum L, in which case this latter may be designed, as to
its periphery, as an ordinary pulley, a grooved pulley, a cog wheel or other trans-
mitting device, which it may be desired to render at will either loose upon or driven
by the shaft.
Or the same effect is produced when the device is adapted to couple two shafts
(as shown) the one part keyed to the boss casing K and the other to the drum L.
The forms, details, accessories, materials, and dimensions of my device can be
varied without departing at all from the essence of my invention.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I declare that what I
claim is:-
The system of disconnecting and throwing into gear by friction, progressively
and elastically;-characterised by the combination of a grooved boss K, keyed on

page_text: to the motor axle; a ring G arranged with the groove of the said boss K, and
mounted loose on the said boss; an external drum L keyed to a driven shaft, or
running on an axle as a pulley or gearing, connected by means of a spring H and
draw band to the ring G; throwing-into-gear screws E, which, exerting a pressure
on the ring G produces the frictional connection between this ring and the boss K;
substantially as described and for the purpose specified, in reference to the drawing
referred to herein.
