Manufactured by The Challenge Tube Cleaner Co. - Lowell, Middlesex County MA
Assigned to George H. Allen - Lynn, Essex County MA

Abstract: The invention is an improvement upon that described in my application for Letters Patent of the United States, filed July 30, 1884, Serial No. 518,933 and it relates to various features of construction whereby clearance is provided the scraping-plates, whereby they are properly supported in action, whereby they are made easily removable, and whereby also they are caused to readily enter the flues. The flue-cleaner of said application has two heads, each conical in form or having conical ribs extending from two end plates, between which the scraping-plates are arranged, the end plates of the heads and scraping-plates being placed so closely together that there is no provision for a self-clearance of the plates and heads in use. My said cleaner also had cleaner-plates which could not be removed from the cleaner without detaching one of the heads. Claim: The flue-cleaner having the scraping-blades D, each of which has a backward-extending tongue or tail provided with the open-ended recess d', whereby the plate may be supported by the rod when in position and may be withdrawn laterally from the rod.

Abstract: My invention relates to that class of tube-scrapers where there are several scraping-edges held in contact with the periphery of the tube by springs, the whole device being fastened upon the end of a long rod, so that it may be thrust through the entire length of the boiler-tube, carrying the dust and soot before it. Claim: In a boiler-tube scraper, the combination of the pair of radially-grooved heads with pairs of scraping-sections supported by the said heads, a central spindle provided with apertures at right angles to its axis, and spiral springs supported in the said apertures, each of the said springs acting upon a pair of the said scraping-sections to force them in opposite directions.
