2. A dispenser for filter paper comprising a housing for enclosing a roll of strip material, said housing having bottom and wall portions and a removable top portion, a slot in said wall portion, means connected to said wall portion adjacent said slot for attaching said housing to a smoke tester, and a cutting edge on said attaching means, said edge being parallel to said slot and spaced from said housing.
1. A dispenser for filter paper comprising a housing for enclosing a roll of strip material, the housing having two parallel end walls, two parallel side walls, a bottom portion integrally connecting said walls, and a removable top, one of said end walls having a slot running from said bottom portion to said removable top, ring like bracket means attached to said one of said end walls adjacent the slot for encircling a portion of a smoke tester, and a serrated cutting edge on said bracket means, said edge being parallel to said slot and spaced from said housing.

Particular difficulty has been found The With reference to FIG. 1, the dispenser is easily attached to a standard spot tester with two set screws 1 which are pre-assembled to the support bracket 6. A one time alignment of the paper slot 5 with a standard spot smoke tester is necessary and easily achieved. The dispenser can 4 is pre-loaded with approximately 15 (more or less) feet of paper 7 providing a sufficient supply for many tests. The filter paper 7 is moved and handled only on the edge protruding from the spot tester, its movement being in increments as determined by the numbers on the paper 7. After a test is complete the strip can be pulled out for overall inspection and the gray density of the test spot 9 can be compared with reference repeating gray scale #8 and separated from the remainder of the roll within the container 4 by using the serrated cutting edge 11 within the container 4 by using the cutting edge 11. The advantage of the test spot 9 under an indexing number 10 is apparent as each test is ready for identification, even though the paper might be dropped or become disorentated.
