US Patent:

41663012, Sep 4, 1979

Filed:

May 26, 1978

Appl. No.:

5/909969

Inventors:

Eugene D. Smith - Bakersfield CA

International Classification:

B08B 902

US Classification:

15 88

Abstract:

Apparatus for cleaning the inside and outside walls of a pipe. The apparatus includes a frame, rail means mounted on the frame, and a carriage mounted on the rail means. Derrick means is cantilevered from the carriage means and carries a stinger to be inserted into a pipe supported on the frame. The stinger carries cleaning means for the inside of the pipe. The carriage also carries cleaning means for cleaning the outside of the pipe. The pipe is rotatably supported on the frame and is rotated while the carriage is moved so as to move the pair of pipe cleaning means along the inside and outside walls of the tube to clean them. Fluid can be injected through the stinger to assist the cleaning of the inside of the pipe.

Abstract:

A turbine wheel in the cavity of a turbine housing is driven by liquid, ordinarily water, introduced into the housing through a conduit which can draw the liquid from a reservoir. The turbine wheel is rotatable on a shaft which is attached to the housing and extends downward through the housing to a position below the housing where a brush is rotatable on the shaft. The brush is driven by the turbine through an arrangement of gears. Openings through the turbine housing are positioned to permit the water passing through the housing to flow downward in a 360. degree. circle around the exterior of the brush. The turbine functions as an air pump drawing air into the housing which aids in forcing the water out the exit openings so that less water volume and pressure is required to force the water out in the 360. degree. circle than would otherwise be necessary. The water with the air falls upon the surface which is to be brushed, so that when the brush device is moved along the surface, the brush rotates on the wet layer on the surface to produce the cleaning action.

Inventors:

Eugene D. Smith - Bakersfield CA

International Classification:

G01M 328

US Classification:

73 491

Abstract:

A pressure tester for pipes including a frame supporting a pair of threaded pipe attachments which can be threaded to the threaded ends of a pipe and are provided with means for injecting liquid under pressure to ascertain the integrity of the pipe under pressure. One of the pipe attachments is axially and pivotally movable relative to the frame and another is vertically and pivotally movable relative to the frame. A tilt elevator can raise one end to tilt the pipe during the filling operation. A vent valve is provided to exhaust air from the pipe so that it can be completely filled with water. Other pipe handling components are also described.
