This invention relates to improvements in ro
tary sleeve valve engines and has for one of its
primary objects to provide a sleeve valve having
,
gear l3 mounted on a shaft |4 driven in any
- suitable manner by the engine.
The two sleeve‘ valves I and 2 have their axes
offset and parallel as is indicated by the respec
a combined reciprocating and oscillating move
tive dot and dash lines l5 and IS in Figure 2
ment with respect to the cylinder and sleeve axes
‘which also shows the sleeve valves to have ring
and an improved ef?cient and simple means for
gears l1 and I8 meshing with ring gears l9 and '
imparting combined movement to the sleeve valve
20 carried by shaft Hi. This shaft I0 has its axes
for insuring a sufficient movement and sliding
offset but parallel with axes l5 and IE to rotate
contact ofthe sleeve valve and its ports therein
with the cylinder in all directions to e?ect a 10 gears l1 and I8 and the sleeve valves I and 2
accordingly in the same direction, while permit

To this end it is'proposed to so arrange the

Each oflthe opposed sleeve valves is provided
with an integral helical driven ring gear and
a correspondingly helical integral cam groove. A

On the outer side of helical
gears I1 and H3 in the sleeve valves | and 2 are
pair of circular concentric ‘driving ring gears 20 formed helical groove guideways 2| and 22 of a‘

Gears I9 and 20 are keyed to collars 23 and
sleeve valves. The cam grooves are such that
ries two circular concentric discs to separately
engage the two helical cam grooves on the sleeve
the discs engaging them cause the two opposed
sleeve valves tobe moved in thevsame linear di
rection back and forth as ‘one moves outwardly
whilezthe other moves inwardly as the driving
gears keep in mesh with the helical driven gears
to rotate the valves.
'
With the foregoing and other objects in view,
the invention resides in the combination of parts
and in the details of construction hereinafter set
forth in the following speci?cation and appendedv
claims; certain embodiments thereof being illus
trated in the accompanying drawing, in which:
Figure 1 is a fragmentary view partly in longi
tudinal section and partly in side elevation of the
opposed sleeve valve ‘construction and actuating
means for, rotation and reciprocation; and
Figure 2 is a schematic view in perspective of
the two opposed offset-sleeve valves and the gear
train for rotating them.
.
.
Referring morev particularly to the drawing, the
two opposed sleeve valves | and 2 are provided
‘with conventional ports 3 and 4 and mounted
for rotational and reciprocatory movement in
24 which are keyed to bushings 25 and 26 receiv
ing wedge pins 2"! and 28 screw threaded in hol
low shaft I0 and retained by suitable snap rings
,29 and 30. Also secured to collars 23 and 24
are tapered 'discs 3| and 32. _Accordingly, as
shaft I0 is rotated the two gears l9 and 20 and
- the two groove guideways 2! and 22 are driven in
the same direction as each other.
However, as
explained in connection with Figure 2, the axes of
the sleeve valves land 2 are offset and the shaft
I0 is oilset to bring gears |9 and 20 in engage
ment with gears I1 and | 8 on opposite sides of
40 top center thereof to impart a rotation to gears‘
I‘! and H3 in the same direction.‘ Discs 3| and
32 are driven ‘in unison with gears I9 and 20 and
engage the helical groovev guideways 2| and 22
of the sleeve valves, Discs 3| and 32 rotate in
constant planes parallel to gears l9 and 20 which
are at right angles to the axes of the shaft Hi
and the sleeves l and 2, whereas spiral groove
.guideways 2| and 22 and. spiral gears l1 and I9,
while rotating in planes parallel to each other,
50 are oblique to the axes of rotation'of the sleeves
| and 2, discs 3| and 32 and gears l9 and 2|).
Due to the fact that the helix of guideway 2| is
equal in pitch to that of guideway 22, disc 3|
ing 9 is va hollow rotatable shaft l0, there being
forces sleeve valve | to be reciproeated to the
