Abstract

A device for driving a train of containers through a pipeline in which a housing rests through trunnions on wheel trucks which support disks taking the pressure of the gas flow passing through the pipeline. The housing has an elastic sealing means closing the gap between the internal surface of the pipeline and the external surface of the housing.

Claims

1. A device for driving a train of containers through a pipeline under the action of gas pressure comprising in combination:

a cylindrical housing having end walls;

a trunnion located on each of the end walls of said housing;

a wheel truck on which said cylindrical housing bears through each of said trunnions;

disks mounted on each of said wheel trucks for closing the cross section of said pipeline to take the pressure of a gas flow passing through the pipeline, said disks having an outer diameter less than the inner diameter of said pipeline; and

an elastic sealing means arranged on said housing adjacent each end thereof for closing the gap between the external diameter of said housing and internal diameter of said pipeline, said sealing means including at least one annular holder secured on said housing, a plurality of adjacent rings disposed on said holder, a plurality of filaments of wear resistant elastic threads secured on each ring and extEnding radially therefrom for engaging the internal diameter of the pipeline and elastic gaskets mounted on said holder between said rings providing a seal between said radially extending threads of the adjacent rings.

2. A device for driving a train of containers through a pipeline under the action of gas pressure comprising in combination:

a cylindrical housing having end walls;

a trunnion located on each end wall;

a wheel truck on which said cylindrical housing bears through each of said trunnions;

disks mounted on each of said wheel trucks for closing the cross section of the pipe line to take the pressure of a gas flow passing through the pipeline, said disks having an outer diameter less than the inner diameter of the pipeline; and

an elastic sealing means arranged on the housing for closing the gap between the external diameter of the housing and the internal diameter of the pipe line, said sealing means including a plurality of axially spaced rows of radially extending wear resistant elastic filaments adjacent each end wall of the housing for engaging the internal diameter of the pipe line; and

elastic gaskets mounted on the housing between the adjacent axially spaced rows of filaments providing a seal between the adjacent elastic filaments.
