  • a nozzle housing 16 is mounted on the housing 10 for rotation about a horizontal axis, and the housing carries a pair of eccentrically directed nozzles 18.
  • the combined action of the reactive thrust of the water streams issuing from the nozzles 18 and the drive action of a turbine in the flow stream of the tank cleaning machine cause the nozzle housing 16 to rotate about the horizontal axis in the direction indicated by the arrows in FIG. 1, and this rotation is accompanied by rotation of the intermediate housing 14 about a vertical axis as indicated by the second set of arrows in FIG. 1.
  • the main stationary housing It ⁇ includes an upper portion 20, and intermediate aperture portion 22 and a lower portion 24.

  • a bevel gear 52 is mounted on the inner end of nozzle housing 16 by means of a pair of snap rings 54 with the bevel gear 52 in mesh with the bevel gear 26 so that as the intermediate housing 14 rotates about the vertical axis, the nozzle housing 16 rotates about the horizontal axis.
  • the bevel gears 26 and 52 have a large number of teeth, but the numbers of teeth on the two gears differ by one so that the spread pattern delivered by the nozzles 18 is non-repetitive for any extremely large number of revolutions of the nozzle housing 16.
  • the bevel gear 52 is freely rotatable with respect to the nozzle housing 16 and is provided with a fluid clutch which permits the nozzle housing 16 to be rotated manually prior to the time hydraulic pressure is applied to the device but provides a susbtantially rigid connection between the nozzle housing 16 and the bevel the gear 52 when hydraulic pressure is applied to the interior of the machine.
  • a generally conical depression 56 is provided in one face of the bevel gear 52, and a piston 58 with a conical end 60 thereon engages the depression 56 to lock the nozzle housing 16- to the bevel gear 52.

  • a spur pinion gear 78 is mounted on the lower end of the turbine shaft 74 by means of a pin 80, and the gear train includes the following gears which are driven sequentially from the pinion 78: spur gears 82 and 84 on shaft 86; spur gears 88 and 90 on shaft 92; spur gears 93 and 94 on shaft 96; and spur gear 98 on shaft 100.
  • These spur gears are connected to the shafts by pins as indicated in FIGS. 2 and 3, and suitable bushingsare provided for mounting the s'hafts in the gear box as illustrated in FIG. 2.
  • the various spur gears rotate in the directions indicated by the arrows in FIG. 3.

  • the ring gear 104 may rotate freely in the housing 14 except for the fact that a shear pin 110 interconnects the ring gear and the rotary housing 14. This shear pin provides protection against shock damage to the spur gears 78-102, since the shear pin will fail and free the ring gear 104 for rotation if the shear pin is subjected to excess shearing forces.
  • bearing and sealing means 112 is provided at the upper end of the shaft 74 where the shaft enters the central chamber between the stationary housing and the gear box 13, and bearing and sealing means 116 is provided on the shaft 74 where the shaft passes from the central chamber 114 into the gear box 13.
  • the upper bearing and sealing means 112 includes a steel disc 118 on the lower side of the turbine 72, a Teflon disc 120 immediately :below the disc 118, a steel disc 122 immediately below the Teflon disc 120, and a Teflon sleeve 124 fitted into the top of the opening in the bottom portion 24 of the stationary housing 10 with the Teflon sleeve 124 having a downwardly facing shoulder engaging the housing portion 24 and an upwardly facing shoulder engaging the steel disc 122.
  • the disc 122 is free to rotate with respect to the disc 120 and the sleeve 124 and the shaft 74 so that the thrust forces set up by the water pressure on the turbine 72 are distributed over both of the opposite faces of the disc 122 while the speed of relative rotation between the disc 122 and each of the discs 120 and 124 is approximately one-half of the speed of relative rotation between the turbine 72 and the stationary housing 10.
  • a similar arrangement is provided for the lower hearing and sealing means 116.
  • a Teflon sleeve 126 similar to the sleeve 124, is mounted in a raised boss 128 on the top of the gear box 13, and a similar Teflon sleeve 130 is attached to the shaft 74 by a pin 132 with a steel washer 134 provided between the sleeves 126 and 130 rotatable with respect to both of the sleeves 128 and 130 and with respect to the shaft 74.
  • a conventional sealing means 136 is also provided below the sleeve 126 around the shaft 74.
  • a plurality of fluid discharge ports 138 are provided at the bottom of the interior chamber 114. These discharge ports 138 are rectangular in shape and serve as screw driver slots to facilitate removal of the gear box 13 from the stationary housing.

Thus, the lower bearing and sealing means 116 is positioned substantially above the bottom of the chamber 114 and has a diameter substantially exceeding the diameter of the shaft 74.
  • the sealing means 116 tends to throw [fluids off of the shaft 74 by centrifugal force, and these fluids seep out of the bottom discharge ports 138 without coming in contact with the access openings to the gear box 13 around the shaft 74. In this manner, the lower sealing and bearing means 116 and the discharge port 1338 help prevent the ingress of corrosive cleaning fluids to the gear box 13.
  • a circular plate 140 is attached to the bottom of the gear box 13 by means of bolts 142, and a radial arm 144 is attached to the center of the plate 140 by means of a pivot pin 146 at the vertical axis of the machine so that the radial arm may be swung around the vertical axis of the machine.
