Abstract
A Expandable Jet Scraper Cup (EJSC) is a resilient member that is attached to a vessel allowing the vessel to pass through restrictions and is used for scraping the interior of a cylindrical object like a pipeline or used to propel a vessel through a pipeline. The EJSC
is a disk-like resilient member 1 that is mounted on the body of a vessel. The EJSC is used to propel a vessel through a pipeline for cleaning or other activities.
The outside diameter of the EJSC is normally larger than the internal diameter of the pipe which causes the outer lip 2 to be compressed providing a seal as the vessel travels along the pipeline. As the vessel travels the outer lip 2 wears and eventually the Edison's outer lip 2 is no longer in contact with the internal pipe wall. Traditional cup design has focused on keeping the scraper lip 2 in close contact with the pipe wall so that a good seal is maintained and no fluid bypasses the vessel. When the scraper lip 2 is in close contact with the pipe wall it will also scrape debris such as wax off the interior of the pipe wall.
In scraping wax off the pipewall, the wax is pushed in front of the vessel causing the wax to build up and slide under the scraper lip and as a result, an even layer of wax may be deposited along the length of the pipeline. The EJSC is designed to allow a calibrated amount of fluid to bypass the EJSC lip 2 so that wax scraped off the pipewall is jetted away. The EJSC is also designed to allow the pipeline operator to take advantage of the resiliency of the scraper cup and expand it laterally as the scraper wears down. Presently once a scraper cup is worn and does not provide an interference fit with the pipe wall it is discarded or refurbished. Refurbishment costs are about two thirds of a new cup. The EJSC can also be refurbished.
The structure of the EJSC is radically different than existing scraper cups as it is designed to allow fluid to bypass between the cup lip and the pipewall jetting away wax and debris and cap be expanded. The jetting and expansion can be used individually or together.

Description
Expandable Jetting Scraper Cup The present invention relates to a scraper cup used to transport pipeline vessels through a pipeline and to clean the interior of a pipeline to ensuring that wax or other debris is not redeposited on the pipe wall.
There are a number of scraper cups on the market, which focus on keeping a tight seal .
between the scraper cup and the pipewall. 'The tight seal is to prevent fluid from passing the scraper cup and to have enough pressure to continue to scrape material ofTthe interior wall of the pipe even after the scraper cup has been worn from traveling down the pipe.
It is the object of the present invention to provide a scraper cup that will allow a calibrated amount of fluid to bypass the scraper cup lip regardless of wear, jet debris scraped off the wall ofthe pipe and ahead of the cleaning vessel so that material will not be able to buildup in front of the vessel and slide back under the lip of the scraper cup.
The design of existing scraper cups allows a percentage of the debris scraped of the wall of the pipe to be forced under the lip of the scraper cup and redepositeded on the pipe wall.
The EJSC is placed on a vessel body using opening 4 and fastened to the body through holes 3. One or more EJSC can be attached to a vessel body, The lip 2 of the EJSC is slotted S so that fluid can bypass lip 2 and jet away any material that has built up in front of EJSC. The slots can be a uniform depth 5 or with an increasing depth 6 as the slot extends to the lip 2 of the EJSC. The slots can either be at 90 degrees to the face of the lip or at an angle to lip 2 to facilitate rotation of the vessel in the pipeline.
Rotation of the vessel in the pipeline will ensure that cup wear is even around the circumference ofthe cup.
The EJSC can be attached to the vessel body 14 using attachment flanges 15 and bolts 16.
The bolting holes are elongated 3 so that as the EJSC is expanded latterly the body of the ESJC is free to move latterly. The EJSC can be expanded in a number of different ways such as:
Example 1 After the lip 2 of ESJC 8 has been worn so that there not suffccient contact with the pipe wall 1.8 an insert ring 6 that is placed between vessel body 14 and EJSC 8.
The process of tightening the fasting bolts 1.6 expands the EJSC 8 latterly to its original diameter over ring 6 and ring 6 is positioned 17 so that the EJSC 8 is held in place and the lip 2 is now in contact 13 with the pipe wall 18.
Example Z Insert rings 7 and 19 are placed between flanges 15 and EJSC 9 when using EJSC 9 for the first time. Once E1SC 9 has worn so that lip 2 is not in contact with the pipe wall 18 rings 7 and 19 are removed. The process of tightening the fasting bolts 16 straightens EJSC 9 so that E1SC 9 is expanded latterly to its original diameter and lip 2 is now in contact 13 with the pipe wall 18.
Example 3 EJSC 10 is manufactured with an expanded body 11. Insert rings 20 and 21 are placed between flanges I S and EJSC 10 is used for the first time. Once has worn so that lip 2 is no longer in contact with the pipe wall 18 rings 20 and 21 are removed. The process of tightening bolts 16 cause EJSC 10 to expand latterly to its original diameter causing lip 2 to come in contact with the pipe wall 18.
