operation of the levers 86 and I06 in the manner
above described is provided for.
The lever I 66 of the selector valve device is also
movable to a second position indicated by a dash
and dot line I61 for opening pipe I64 to the
atmosphere and for connecting pipe I63 to the
?uid pressure supply pipe I33. In this position
of lever I66 ?uid under pressure will then ?ow
to pressure chamber I6I and move the piston
I59 in the direction of the right hand. This
movement of the piston will operate the lever
I56 to shift the sleeve 10 longitudinally of the
sleeve 65 in the direction of the right-hand,
and with the lever 86 disposed in the same plane

in the position shown it opens pipe I19 to the
atmosphere and connects pipe I8I to the ?uid
pressure supply pipe I33 to thereby supply ?uid
to chamber I86 at one side of the'piston, I12.
Since at this time chamber I18 at the opposite
side of piston I68 is open to atmosphere, the
pressure in chamber I80 acting on piston I12
will shift the shaft 54 longitudinally relative to
the members 64 and 63 and sleeve 65 to the

lever 82 disposed in the same plane as lever 80,
as lever I66, as in neutral position of both of 30 as with both levers in their idling positions, the
said levers, the slot 16 in member 12 will be
aligned with the key 15 so that said key will enter
said slot and be moved into engagement with the
inner end thereof. In this position of key 15 a
portion of it will be disposed in each of the mem
bers 12 and 1! thereby securing the two levers
86 and I96 together for movement in unison.
With the two levers 86 and I66 thus secured to

operation of the two ?uid motors 5! and 29 and
thereby like positioning of the maneuvering
slot 69in member 64 will be aligned to receive
the key 68 so that the piston I69 will move the
shaft 54 to a position de?ned by contact between
said piston and the inner wall of the bore in
which it operates andin which the key 68 will
be disposed partly in‘ slot 69 in member 64 and
partly in the sleeve 65 thereby securing the lever

operation of said two valve control means, said
selector means being movable to a second posi
tion, and means responsive to movement of said
selector means to said second position to discon
