Abstract
Abstract An improved apparatus for cleaning large tanks or vessels, such as automotive and railway tank cars. A tiltable frame having a wash nozzle assembly pivotedly mounted thereon is pivotedly mounted above a fixed support frame. The tiltable frame has, fixedly mounted thereon, an air motor which is operatively connected to a first gear box which, in turn, is operatively connected to a second gear box. The first gear box is operatively connected to the wash nozzle assembly to move said assembly back and forth along the longitudinal axis of the tank or vessel to be cleaned. The second gear box is operatively connected to the fixed support frame to tilt the tiltable frame and thereby move the wash nozzle in both directions along the latitudinal axis of the tank or vessel to be cleaned.

Claim 3
Dependent Claim
52 words
An apparatus for cleaning tanks or vessels as recited in claim 1, wherein said mechanical means for continuously moving said spray means back and forth along the longitudinal axis of the tank or vessel to be cleaned is a gear box operatively connected to said spray means by a lever arm mechanism.
Claim 4
Independent Claim
123 words
An apparatus for cleaning tanks or vessels, comprising: (a) a fixed support frame; (b) a tiltable frame pivotedly mounted above said fixed support frame; (c) a wash nozzle assembly pivotedly mounted to said tiltable frame; (d) an air motor fixedly mounted to said tiltable frame; (e) a first gear box fixedly mounted to said tiltable frame; (f) a second gear box fixedly mounted to said tiltable frame; (g) means for operatively connecting said air motor and said first gear box; (h) means for operatively connecting said first gear box and said second gear box; (i) means for operatively connecting said first gear box and said wash nozzle assembly; and (j) means for operatively connecting said second gear box and said fixed support frame.
