Abstract
Abstract A method of and apparatus for cleaning drums of the type having a bung opening in the cover which employs a tank having a plurality of nozzle pipes positioned in the tank. The nozzle pipes are stationary or in a fixed position, one for each drum to be cleaned. The drums are supported so that their bung openings are facing and in alignment with the nozzle pipes. The drums are moved over the stationary nozzle pipes and retracted. During the reciprocable movement of the drums a cleaning solution is sprayed against the interior surfaces of the drums.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
24 words
A method as set forth in claim 1 comprising oscillating the nozzle pipes about their respective longitudinal axes during the movement of the drums.
Claim 2
Dependent Claim
134 words
Apparatus for cleaning drums of the type including a cOver having a bung opening, the apparatus comprising a tank, a plurality of stationary, vertically extending nozzle pipes positioned in the tank in longitudinally spaced relation, a drum support for a plurality of drums mounted for reciprocable movement into and out of the tank in a plane parallel to the longitudinal axes of the nozzle pipes, the drum support comprising a pair of longitudinally spaced end plates, first and second longitudinally extending, transversely spaced support members secured to the end plates, the transverse spacing of the support members being less than the diameter of a drum, and means for imparting reciprocable movement in a vertical plane to the drum support to permit spraying the interior surfaces of the drums during the movement of the drums.
Claim 3
Dependent Claim
55 words
Apparatus as set forth in claim 3, wherein the first support member is at a lower level than the second support member, and a third longitudinally extending support member secured to the end plates, the third member being positioned rearward of the first support member and at a higher level than the second support member.
Claim 4
Dependent Claim
19 words
Apparatus as set forth in claim 3 including means for oscillating the nozzle pipes about their respective longitudinal axes.
Claim 5
Dependent Claim
21 words
Apparatus as set forth in claim 3 including guide means for each nozzle pipe secured to one of said support members.
Claim 6
Dependent Claim
20 words
Apparatus as set forth in claim 6 including guide means for each nozzle pipe secured to the first support member.
Claim 7
Dependent Claim
25 words
Apparatus as set forth in claim 3 including a stationary frame extending into and above the tank, the end plates being positioned adjacent the frame.
Claim 8
Dependent Claim
40 words
Apparatus as set forth in claim 8, wherein the frame comprises a vertically extending I-beam located at each corner of the tank, and cooperable means connected to the end plates and provided by the I-beams for guiding the drum support.
Claim 9
Dependent Claim
170 words
Apparatus for cleaning drums of the type including a cover having a bung opening, the apparatus comprising a tank, a plurality of stationary, vertically extending nozzle pipes positioned in the tank in longitudinally spaced relation, a main pipe in flow communication with the nozzle pipes, a pump exterior of the tank in communication with the main pipe, a return pipe in communication with the bottom of the tank and the pump, a drum support for a plurality of drums mounted for reciprocable movement into and out of the tank in a plane parallel to the longitudinal axes of the nozzle pipes, the drum support comprising a pair of longitudinally spaced end plates, first and second longitudinally extending, transversely spaced support members secured to the end plates, the transverse spacing of the support members being less than the diameter of a drum, and means for imparting reciprocable movement in a vertical plane to the drum support to permit spraying the interior surfaces of the drums during the movement of the drums.
Claim 10
Dependent Claim
55 words
Apparatus as set forth in claim 10, wherein the first support member is at a lower level than the second support member, and a third longitudinally extending support member secured to the end plates, the third member being positioned rearward of the first support member and at a higher level than the second support member.
Claim 11
Dependent Claim
19 words
Apparatus as set forth in claim 10 including means for oscillating the nozzle pipes about their respective longitudinal axes.
Claim 12
Dependent Claim
21 words
Apparatus as set forth in claim 10 including guide means for each nozzle pipe secured to one of said support members.
Claim 13
Dependent Claim
20 words
Apparatus as set forth in claim 13 including guide means for each nozzle pipe secured to the first support member.
Claim 14
Dependent Claim
25 words
Apparatus as set forth in claim 10 including a stationary frame extending into and above the tank, the end plates being positioned adjacent the frame.
Claim 15
Dependent Claim
40 words
Apparatus as set forth in claim 15, wherein the frame comprises a vertically extending I-beam located at each corner of the tank, and cooperable means connected to the end plates and provided by the I-beams for guiding the drum suppoRt.
