Abstract
Abstract Coffee filter selector apparatus includes a housing having a continuous length of adhesive material for contacting a coffee filter and for removing the contacted coffee filter from a stack of nested coffee filters. The adhesive material is manually wound from a supply reel over an idler wheel, which extends out of the housing and onto a takeup reel. The takeup reel includes outer peripheral notches for a ratcheting system and for allowing a predetermined linear length of adhesive to be advanced from the supply reel onto the takeup reel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
Apparatus for adhesively removing an element from a stack of elements, comprising, in combination: base means for supporting elements secured thereto; tape means secured to and movable on the base means, including a length of tape having an ashesive side for contacting the element and for adhering to the contacted elements, and takeup roller means secured to the length of tape for advancing the length of tape, including a takeup roller, and a takeup wheel secured to the takeup roller and movement of the takeup wheel causes movement of the takeup roller to advance the length of tape; and means for advancing the takeup roller means a predetermined distance to advance the length of tape, including a plurality of spaced apart notches on the takeup wheel, with the space between the notches corresponding to the predetermined distance which the length of tape advances, and means extending into a notch for limiting the movement of the takeup wheel.
