This invention relates to speed changing fluid '
power transmission and clutch devices and has for
one of its objects to improve generally upon such
devices.
More specifically, another object is to produce a
device of its kind of simple yet practical and
durable construction, which is easy to manufac
ture, easy to control and operate, durable and
long lasting, and operable without failures com
mon to many devices of this character hereto
fore produced and in present-day use.
Other objects and advantages to be attained
` will hereinafter more fully appear in the follow
innerface portions of said cylinder heads 5 and
6 concentrically with the axis of the driven shaft
I. The fitting of the endV portions of the cylinder
9 in said annular grooves 9’ is made relatively
tight so as to permit rotation of the cylinder 9 in
said grooves 9', yet the fitting isV substantially
leak-tight.
YA plurality of partition and abutment cylinders
I0 (four in number,ras shown) are provided `and
arranged and adapted to rotate and roll between
the inner cylinder 3 and outer shell 4, in a manner
and for a purpose to be presently more fully de
scribed, said cylinders I0 being located to work in

port 30. By` this particular provision, actuation
of the'lever 28 in one direction imparts a longi
tudinal movement of the iiexible rods 22 inward
ly and accordingly moves the arms I9 of the disc
or sector elements I8 in the direction to corre
spondingly rotate the valve ring I5 in the direc
tion to open the ports i 5’ thereof into communi
cation with the ports I5 in the cylinder head 5,
at which time the outer shell 4 of thedevice is
stationary or the device is idling, that is tosay,
if the outer shell 4 is rotating no rotative move
ment is imparted to the inner cylinder 3 and
its attached driven shaft I.
Movement of the operating lever 28 in the oppo
site direction imparts a partial rotation of the
valve ring I5 in the direction opposite to that
in which i-t has just been operated, that is to say,
in the direction >to close the ports I6 in the cylin
der head 45. By the provision for the manual
operation of the valve ring I5, just 'above de
scribed, the valve ring remains in its operated
position until reversely operated.
An example of a mechanical provision for con
ltrolling and operating the valve ring I5 is illus
trated in Figure 7. In this illustration, the mech
anism connecting directly with the valve ring it
self and extending through the hub portion 8’
of the housing or casing 8 and including the

the device are iilled with a non-compressible ñluid
and the chamber 3'I within the end housing or
casing 8, constituting a reserve supplyy cham~
ber, is filled substantially to near the top there- ‘
of, or at least to a level abovethe uppermost port
I5’ in the valve ring I5. The relatively small air
space in the chamber >3'I is to contain suñicient
air to permit expansion of the fluid under .heat
but in any case the level of the fluid in said chain
ber 31 must be high enough to cover the upper
most ports I5' in said valve ring I5 so that no>
appreciable amount of air, if any, is admitted into
the chambers 36 within the cylindrical shell 4
of the device.
.
With the chambers 36 and 31 thus filled and
with the valve ports I5’ open to full communica
tion with the ports I6 in the cylinder head 5, the
driven shaft 2 and its attached inner cylinder
3 are rotatable freely Without any eifect on the
outer cylindrical shell 4 and driving shaft I.
However, if the valve ring I5 is turned so as to
close or partially close the ports I6 in the cyl
inder head 5 the fluid is confined in the respective
chambers 36 and being so confined with the cyl
inders I0 in certain positions relative to the ribs
I á on the outer shell 4 and those I I’ on the inner
cylinder 3, and the rounded edge portions of said
ribs II and II’ in wiping contact with the inner
and outer faces of the intermediate sleeve 9, there
