Claim 1
Independent Claim
263 words
A machine for cleaning the outer surface of a trunk pipeline, comprising, a frame movable along the pipeline to he cleaned, means mounted on said frame for moving said frame along the pipeline to be cleaned, at least one working member mounted on said frame and having a housing and a rim, the housing of said working member comprising of a clamp open from below and mounted on said frame, and two brackets, each of which is mounted on one of the ends of said clamp and adapted to be moved down and turn away from the pipeline being cleaned when the machine is dismantled and upward and back to the normal position when the machine is mounted, support rollers mounted in the clamp and in the brackets of the housing of said working member along a circumference coaxial to the pipeline to be cleaned so that the axes of rotation of said support rollers are parallel to the axis of the pipeline to be cleaned, the rim of said working member being mounted in the housing thereof, between the clamp and the brackets, on said support rollers, and carrying tools for cleaning the surface of the pipeline as said ring-shaped rim rotates around said pipeline and the frame moves simultaneously along the pipeline, said rim comprising two half-rings to facilitate installation of said rim on the pipeline and dismantling thereof, a drive to rotate said rim around the pipeline, in the form of a sleeve-and-roller chain secured to the outer surface of said rim, and means for rotating said sleeve and-roller chain.
Claim 2
Dependent Claim

A machine for cleaning the outer surface of a trunk pipeline, comprising, a frame movable along the pipeline to he cleaned, means mounted on said frame for moving said frame along the pipeline to be cleaned, at least one working member mounted on said frame and having a housing and a rim, the housing of said working member comprising of a clamp open from below and mounted on said frame, and two brackets, each of which is mounted on one of the ends of said clamp and adapted to be moved down and turn away from the pipeline being cleaned when the machine is dismantled and upward and back to the normal position when the machine is mounted, support rollers mounted in the clamp and in the brackets of the housing of said working member along a circumference coaxial to the pipeline to be cleaned so that the axes of rotation of said support rollers are parallel to the axis of the pipeline to be cleaned, the rim of said working member being mounted in the housing thereof, between the clamp and the brackets, on said support rollers, and carrying tools for cleaning the surface of the pipeline as said ring-shaped rim rotates around said pipeline and the frame moves simultaneously along the pipeline, said rim comprising two half-rings to facilitate installation of said rim on the pipeline and dismantling thereof, a drive to rotate said rim around the pipeline, in the form of a sleeve-and-roller chain secured to the outer surface of said rim, and means for rotating said sleeve and-roller chain.
Claim 3
Dependent Claim
123 words
A machine as claimed in claim 1 wherein the clamp of the housing of said working member comprises a crosspiece fixedly attached to the frame and carrying the upper support rollers, and two side portions, each of which is attached to one of the ends of said crosspiece, each of said brackets being movable up and down and turned by means of a bar mounted in a guide provided in a respective side portion of said clamp, each of the brackets being rigidly attached to the lower end of a corresponding bar, whose upper end is connected to a screw pro-vided in the crosspiece coaxially to said bar for effecting axial movement of said bar and turning said bar around its own axis.
Claim 4
Dependent Claim
98 words
A machine as claimed in claim 1, wherein the outer surface of each of the half-rings of the rim of the working member is provided with a semi circular groove of a rectangular cross-section to receive therein a respective portion of the sleeve-and-roller chain of the rim rotation drive, the ends of said portion of the sleeve-and-roller chain being attached to the rim half-ring at a distance equal to half of the link pitch of said chain from the plane in which the rim half-rings are joined so that the chain is continuous when the rim is closed.
Claim 5
Dependent Claim
23 words
A machine as claimed in claim 3, wherein each of the rim half rings is split along the outer wall of the groove.
