after which the relatively rotatable parts of the
transmission rotate in unison.
It is an object of the invention toprovide a
transmission which is relatively simple and com

A lfurther object of the invention is to pro

means for applying the offsetting force to the
wobble plate in such manner that excess pressure
will not be exerted betweenthe socket of the
wobble plate and the ball, whereby the wobble

A further object of the invention is to provide

end plate 20 having a shaft element 2| which
projects through an opening 22 in the end plate
I9 and through a seal 23 carried by the end plate
I9 to prevent leakage of~oil from the interior
of the hollow body member I I, around the project
ing shaft element 2|. This shaft element 2| pro
vides a means for connecting the body I9 to the
part to be driven.
The first body member I0 has a plurality of cyl
inders 24 disposed in positions to face the leitward
ends thereof, these cylinders 24 being disposed
around the axis of rotation of the members IB '
and Il and lying on axes which extend along
the axis of rotation. The axes of the cylinders
24 are most conveniently >made parallel to the
axis of rotation of the members Ill and_ I I, but
it will be recognized that some angularity be
tween the axes of the cylinders 24 and the axis of
rotation A-A may be permitted. Pistons 25 are
tracted position as shown in full lines, the dogs 42
may be encircled by a ring 43 which may be
shifted rightward from the position in which it is
shown, thereby locking the weights 39 against
outward movement. The locking ring 43 is con
nected by pins 44 with a ring 45 axially shifta-ble
on the shaft member I5. Being externally posi
tioned with relation to the body member II, the
ring 45 may be engaged at any time and shifted
rightward so as to lock the centrifugal governor
against operation, such locking being desirable
’during any operation of the engine for checking
its ignition, tune up, etc.
The inner or rightward ends of the cylinders
2,4 communicate with the interior of the device
,through ports 43 placed so that they connect
with the portions of the cylinders lying at mini
mum radial distances from the axis of rotation
A-A. These ports 46, being so positioned, enable

to as being supported in non-rotative relation to
the body member I0.
'
A sleeve 35 is slidable upon theshaft 33 and at '
its rightward end has an arm 36 from which an
engager 31 projects toward the swingably sup
ported body 3|. vThe engager 31 is spaced from
the axis A-A a distance only slightly less than
the radial distance between the axis A-A and
the axes of the pistons 25. The sleeve 35 sup
ports pins 38 on which governor weights 39 are
swingable from the retracted positions in which
they are shown in full lines to the extended posi
tions shown by broken lines 39a. Y Levers or dogs
40 carried by the inner ends of the governor
weights 39 engage a groove 4I in the shaft 33, so
that when the governor weights 39 swing outward
toward the positions 39a thereof, the sleeve 35
will be shifted rightward, the engagement mem
ber 31 then forcing the operating member 3| into
a diagonal position such as indicated by broken
lines Bla. Then, if the driving body member I I is
the rear ends thereof are connected to an axial
ly movable member 54 against which the spring
52 presses. The rightward end of the spring 52
engages a nut 55 supported by a screw 56 within
a recess 51 in the shaft element 2|. The nut 55
has notches 58 at the rightward end thereof
which may be engaged by a tool inserted through
an opening 59 in the wall of the member 2|,
whereby the nut 55 may be rotated on the screw
56 to adjust the compression in the spring 52,
This opening 59 is normally closed by a plate 69,
of cylindric form and having an opening 6I
which may be brought into registry with the
opening 59 by rotation of the plate 69.
The operation of the device is as follows.
When the body member | I is rotated at low
speeds, such as the idling speed of the engine by
which it is driven, springs 62', connecting the
governor weights 39, will hold these weights in
retracted position, and the engager 31 will be re
65 tracted into a position such as shown in full
lines in Fig. l, so that the operating member 3|
may assume a position normal to the axis A-A.
The wobble plate 21 will atthis time be in a po
