I ARTHUR SYDNEY BOWLEY of Elm Lodge Mitcham in the county of Surrey
Merchant do hereby declare the nature of this invention to be as follows:--
The object of my invention is to provide a very simple and cheap and yet an
extremely sure and efficient clutch for use whereever the same is required to cause
one shaft or other appliance to revolve with another only when the latter is revolved
in the one direction.
To carry out this object I secure concentrically on the one shaft or other appliance
a ring the inner periphery whereof may be plane or grooved or V shaped or otherwise.
On the other shaft or appliance 1 secure a spiral shaped cam the outer edge or
periphery whereof preferably corresponds with the inner periphery of the ring and
between these two peripheries are placed a number of rollers or cones or balls or
other similar appliances suitable for use with the particular forms of the peripheries
which rollers or other appliances are of such different sizes or diameters as duly to fill
the space between the spiral periphery or edge of the cam and the inner periphery
of the concentric ring. At or near the shoulder or elbow that must obviously be
formed by this spiral edge of the cam can be fitted an adjustable stop behind which
is a spring to force and keep all the rollers or other appliances close together.
When this cam is revolved in the one direction it is obvious that the rollers or
other appliances will be jammed tightly between the spiral edge of the cam and
the inner periphery of the concentric ring whereby this ring will be revolved
therewith but when the cam is revolved in the other direction it is also obvious
that the rollers or other appliances will be allowed to run freely and the ring will not
be revolved therewith.

I ARTHUR SYDNEY BOWLEY of Elm Lodge Mitcham in the county of Surrey
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:-
The object of my invention is to provide a simple and cheap and yet efficient
clutch for use where ever the same is required to cause one shaft or other appliance
to revolve with another only when the latter is revolved in the one direction.
In order the more clearly to explain this my invention and in what manner the
same is to be performed I refer to the accompanying drawings in which I have
shewn so much of my apparatus as is necessary for the clear comprehension thereof.
Figure 1 is an elevation of the apparatus shewing the working parts and Figure 2
is a transverse section of the same taken at a. b. in Figure 1.
To carry out the object of my invention I secure concentrically the ring A-the
inner periphery E whereof may be plane or grooved or V shaped or otherwise on
the one shaft or other appliance F. On the other shaft or appliance D I secure the
spiral cam C the outer edge or periphery G preferably corresponds with the inner
periphery E of the ring A and between these two peripheries G and E are placed
a number of rollers B. or cones or balls or similar appliances suitable for use with the
particular forms of the peripheries G and E which rollers or other appliances are of
such different sizes or diameters duly to fill the space between the spiral periphery
or edge G of the cams C and the inner periphery or edge E of the concentric ring A.
At or near the shoulder or elbow H can be fitted an adjustable stop behind which is
a spring to force and keep all the rollers or other appliances close up together.
When the cam is revolved in the one direction it is obvious that the rollers or
other appliances will be jammed tightly between the spiral edge G and the inner
periphery E of the concentric ring A whereby this ring A will be revolved therewith,
but when the cam C is revolved in the other direction it is also obvious that the
rollers B or other appliances will be allowed to run freely and the ring A will not be
revolved therewith.
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. The combination of the Cam C the rollers B and the surfaces E and G.
"
2. The "clutch substantially as herein before described and shewn in the
accompanying drawings.
