projecting bodies 2i are also provided with bores
2S which lead inwardly from the rear ends of
the bodies 2l and connect with the rearward ends
of the cylinders 22 so as to provide ports 21 which
communicate through openings 2t with an in
ternal oil space or reservoir 23.
The front end of the oil space 29 is closed by a
radial wall 35 having a threaded counterbore Si
and a rearwardly -extending tubular portion'32,
the rearward portion of the tube 32 beingsup
ported by webs 33. At the rearward end of the 20
tube »32 there is a spider 34 having a cylindrical
wall in sliding engagement with the rearward
end of the tube 32. This spider is axially mov
able-and carries thereon cylindrical valve closures
,36 which slide in the bores 2t and have their for 25
ward ends 3l shaped so as to cooperate with the
channel ‘Il of arcuate cross-section in which the
roller 52 may roll.
In Fig. 1 the device is shown with its parts in
positions which they assume during operation.
The tubular member 40 is in rotation, and con
sequently the >weights 4S are swung outward, with
the result that the gear segments 44 have been
rotated in va direction to pull the bar 55 leftward
and thereby move the valve member-s 36 toward
theports ‘2T of the cylinders so as to restrict the
flow of liquid through the ports. At the same
time lthe cams5i) of the-counterweight meansare
rotated inward toward the axis a-aso as to
force the vsleeve 49 and the ñange 6| rightward,
thereby moving the roller.62 in rightward direc
tion so that the wobble plate 61 is swung into a
diagonal position. The nange 6l is in rotation
and the 'teeth V6|’ thereon engage the teeth l62'
formed at the inner side of the roller 52 to cause
it to roll around the groove 7l of the wobble
plate. Whether or not this rolling occurs and
the relative velocity ofthe roller on the shaft 63,
both depend upon whether or not the driven
member A is in rotation. For example, if the
driven member A is rotated at ythe same rate of
speed as the ñange 6l, the wobble plate vand the
shaft 63 will rotate in unison with the flange El
around the axisa-a. On the other hand, should
the driven member YA be stationary, the wobble
plate B5 willnot bein rotation around the axis
a~-a and the roller E2 will roll around the groove
ports »i3-‘l so that the flow of oil through the ports
2ï may be varied. The spider 34 has a counter
bore «38 in which a thrust bearing 3G operates
as Vwill be hereinafter described.

The rotatable member B includes a tubular body
¿ü which rotates in the bearings i8 and 2U, the
leftward end of »this tubular body directly en
gaging the inner part of the bearing 20 and
the rightward portion of the tubular body 4b 35
having axially slidable thereon a sleeve si, which
sleeve ¿i in turn-engages the inner race of the
bearing i5. The sleeve or tubular body ¿i6 is
splined at ¿i2 to receive the shaft Ii, and inter
mediate the ends thereof has diametrally dis
posed slots £3 through which gear segments lill of

65 ing of the flange -Si will in turn gradually
rightwardly shift the roller~t2 so that the 4wob
ble plate 66 will be first caused to oscillate
through a small angle and produce short re
ciprocations of the >pistons 23 which will be
gradually `increased ingkeeping with the increase
of wobble'imparted to .the wobble plate as the re
sult of the continued outward movement of the
counterweights `49. The wobble plate, when os
cillated, impar-ts torgue impulses to the project
ing ends~24 vof the pistons, f:through which these
2,408,574
torque impulses are ca'rriedtol the shell l2 and
the shaft I0 yof the ydriven member A. During
.thel'starting of the power transmitting' eñect,
the wobble plate'is‘oscillated at high velocity,
butthrough relatively small angles so that rela
tively >rapid torque impulses are transmitted from
the 'drive member Bto the driven member A, and
as the'counterweights 49 swing outwardly, .the
angular movement of the wobble plate is in-î
creased,"but, since the’drivenA member» A has
started to rotateand will normally continue to
accelerate, ythe speed of the flange 6I relative .to
the driven member A will decrease, and the ra
pidity of the torque impulses will likewise de
crease, but will be of'grea'ter strength vdue to the
increased angularity of the’wobble plate 66.
