Abstract: This invention relates to a filter paper dispenser so designed that with ease of attachment to a Spot Smoke Tester, a ready supply of clean, indexed, and calibrated filter paper is quickly available for smoke spot testing. SUBACKGROUND OF THE INVENTIONParticular difficulty has been found in the present method of spot testing the smoke content in the flu pipe of an oil burner. Namely, that the filter paper in common use today is in strip form and obtained by the technician tearing off a useable piece of paper from a serrated sheet to form a useable strip. Herein lies one of the difficulties. Usually the technician making the test has either serviced the oil burner or had made an inspection. As a result has hands are quite often covered by a quantity of soot, oil dust, and etc,. inherent with and generally found around an oil burner. Hence, the moment he selects a filter strip he imparts a print or smudge from his hands onto the filter paper even before he makes a test.
