Vacuum loading machine

A vacuum loading machine which comprises:

• a body including
• a chassis and
• a tank on the chassis for holding material;
• means for creating a vacuum in the tank;
• a hose through which material is sucked into the tank by the vacuum;
• a boom assembly supporting the hose and providing a conduit through which material from the hose is sucked into the tank, the boom assembly being capable of being extended longitudinally, the boom assembly pivoted to be capable of vertical movement;
• valve means within the boom assembly for closing the conduit through the boom assembly;
• a first fluid cylinder on the boom assembly actuatable to extend and retract the boom assembly;
• a second fluid cylinder on the boom assembly actuatable to cause the valve means to close the conduit;
• a third fluid cylinder on the boom assembly actuatable to raise and lower the boom assembly;
• fluid supply on the body;
• a swivel assembly for mounting the boom assembly on top of the body and for rotating the boom assembly 360.degree. with respect to the body, the swivel assembly including multiple fluid passage means through the swivel assembly to permit fluid to pass to the first, second and third fluid cylinders on the boom assembly from the fluid supply and control means on the body during the entire 360.degree. rotation of the boom assembly.

A liquid dispensing machine comprising:

• a body including
• a chassis and
• a tank on the chassis for containing a supply of liquid;
• a hose connected to the tank for dispensing the liquid;
• a hose reel assembly for supporting the hose, the hose reel assembly being mounted on the body;
• means for swinging the hose reel assembly outwardly away from the body and inwardly back toward the body, the swinging means comprising:
• an actuator having one end attached to the body, the actuator producing a range of movement and being securely locked in place when not moving, and
• a linkage assembly having one end attached to the other end of the actuator and having the other end attached to the hose reel assembly, the linkage assembly extending the range of movement provided by the actuator.
