Abstract
Abstract An apparatus and method for removing material from a surface so that the removed material will not escape into the ambient environment are disclosed. The present invention includes a coagulant-applying mechanism for spraying a coating of coagulant on the material to be removed. Also included is a cutter head assembly which is moved along the surface for scraping the material therefrom. So that the scraped, coagulated material may be safely withdrawn to a storage receptacle, the present invention also includes a mechanism which withdraws the loosened, coagulated particles from the cutter head assembly. The system of the present invention incorporating these elements also includes a sampling container for extracting and storing a portion of the subject material for examination thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
186 words
A system for removing a substance, comprising: sampling means for sampling the substance to obtain a portion for testing the composition thereof, said sampling means including: a first open-ended container having an aperture extending through the side wall thereof; a second open-ended container engaged within said first container for slidable extension through the open end thereof, said second container having a latch-receiving member disposed thereon in alignment with the aperture of said first container; latch means extending through the aperture of said first container in releasable abutment with the latch-receiving member of said second container for preventing said second container from slidably extending from said first container when said latch means abuts the latch-receiving member; and closure means for closing the open end of said first container; coagulent applying means for applying a coating of a coagulant to the substance to be removed when the sampled portion is a predetermined type of substance; scraping means, associated with said coagulant applying means, for scraping the surface to loosen the substance therefrom; and means, associated with said scraping means, for withdrawing the loosened substance from the scraped surface.
Claim 2
Independent Claim
186 words
A system for removing a substance, comprising: sampling means for sampling the substance to obtain a portion for testing the composition thereof, said sampling means including: a first open-ended container having an aperture extending through the side wall thereof; a second open-ended container engaged within said first container for slidable extension through the open end thereof, said second container having a latch-receiving member disposed thereon in alignment with the aperture of said first container; latch means extending through the aperture of said first container in releasable abutment with the latch-receiving member of said second container for preventing said second container from slidably extending from said first container when said latch means abuts the latch-receiving member; and closure means for closing the open end of said first container; coagulent applying means for applying a coating of a coagulant to the substance to be removed when the sampled portion is a predetermined type of substance; scraping means, associated with said coagulant applying means, for scraping the surface to loosen the substance therefrom; and means, associated with said scraping means, for withdrawing the loosened substance from the scraped surface.
Claim 3
Dependent Claim
113 words
A substance sampling apparatus, comprising: a first open-ended container having an aperture extending through the wall thereof; a second open-ended container having a cutting means adjacent said open end engaged within said first container for slidable extension through the open end thereof, said second container having a latch-receiving member disposed thereon in alignment with the aperture of said first container; latch means extending through the aperture of said first container in releasable abutment with the latch-receiving member of said second container for preventing said second container from slidably extending from said first container when said latch means abuts the latch-receiving member; and closure means for closing the open end of said first container.
Claim 4
Dependent Claim
113 words
A substance sampling apparatus, comprising: a first open-ended container having an aperture extending through the wall thereof; a second open-ended container having a cutting means adjacent said open end engaged within said first container for slidable extension through the open end thereof, said second container having a latch-receiving member disposed thereon in alignment with the aperture of said first container; latch means extending through the aperture of said first container in releasable abutment with the latch-receiving member of said second container for preventing said second container from slidably extending from said first container when said latch means abuts the latch-receiving member; and closure means for closing the open end of said first container.
Claim 5
Independent Claim
182 words
A system for removing asbestos, comprising: sampling means for sampling a substance to obtain a portion for testing to determine if the substance is asbestos, said sampling means including: a first open-ended container having an aperture extending through a side wall thereof; a second open-ended container disposed within said first container for slidable extension through the open end of said first container, said second container having a latch-receiving member disposed thereon; latch means extending through the aperture of said first container in releasable association with the latch-receiving member of said second container for preventing said second container from slidably extending from said first container when said latch means is releasably associated with the latch-receiving member; and closure means for closing the open end of said first container; coagulant applying means for applying a coating of a coagulant to the substance to be removed when the sampled portion is asbestos; scraping means, associated with said coagulant applying means, for scraping the surface to loosen the substance therefrom; and means, associated with said scraping means, for withdrawing the loosened substance from the scraped surface.
Claim 6
Independent Claim
182 words
A system for removing asbestos, comprising: sampling means for sampling a substance to obtain a portion for testing to determine if the substance is asbestos, said sampling means including: a first open-ended container having an aperture extending through a side wall thereof; a second open-ended container disposed within said first container for slidable extension through the open end of said first container, said second container having a latch-receiving member disposed thereon; latch means extending through the aperture of said first container in releasable association with the latch-receiving member of said second container for preventing said second container from slidably extending from said first container when said latch means is releasably associated with the latch-receiving member; and closure means for closing the open end of said first container; coagulant applying means for applying a coating of a coagulant to the substance to be removed when the sampled portion is asbestos; scraping means, associated with said coagulant applying means, for scraping the surface to loosen the substance therefrom; and means, associated with said scraping means, for withdrawing the loosened substance from the scraped surface.
