Abstract

Abstract My invention relates to means for maintaining the interior of a tape player cabinet free of dust and other like deleterious material, and comprises a hollow suction nozzle having a forward end with an outside rectangular contour to closely conform to, and fit within, the rectangular opening in the tape player cabinet. The nozzle has an exterior shoulder for abutment with the exterior face of the cabinet margining the rectangular opening to limit insertion of the nozzle forward end an amount short of interference with the operating mechanism within the cabinet. A rubber ring stretched around the nozzle may be moved to seal the rectangular opening. A small transverse hole is formed in the nozzle and is used to control the amount of suction produced within the nozzle by a conventional suction cleaner.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 136 words
Means for maintaining the interior of a tape player cabinet free of dust and other like deleterious material, said cabinet having a rectangular opening of definite dimensions through with a conventional tape cartridge is inserted, comprising: a hollow suction nozzle having a forward end with an outside rectangular contour conforming to said rectangular opening and dimensioned to closely but freely fit within said rectangular opening, said nozzle having a rear end adapted to be connected to a suction hose of a vacuum cleaner, and an exterior shoulder on said nozzle spaced rearward of its forward end a predetermined amount so that abutment of said shoulder with the exterior face of said cabinet margining said rectangular opening limits insertion of said forward end into said cabinet an amount short of interference with operating mechanism within said cabinet.
Claim 2
Dependent Claim 136 words
Means for maintaining the interior of a tape player cabinet free of dust and other like deleterious material, said cabinet having a rectangular opening of definite dimensions through with a conventional tape cartridge is inserted, comprising: a hollow suction nozzle having a forward end with an outside rectangular contour conforming to said rectangular opening and dimensioned to closely but freely fit within said rectangular opening, said nozzle having a rear end adapted to be connected to a suction hose of a vacuum cleaner, and an exterior shoulder on said nozzle spaced rearward of its forward end a predetermined amount so that abutment of said shoulder with the exterior face of said cabinet margining said rectangular opening limits insertion of said forward end into said cabinet an amount short of interference with operating mechanism within said cabinet.
Claim 3
Dependent Claim 58 words
The construction according to claim 1 and further including an endless resilient member disposed transversely of said nozzle and resiliently engaging the same, said member being free to move longitudinally of said nozzle and being adapted for movement to abutment with said cabinet face and seal around said rectangular opening when said nozzle is inserted within the latter.
Claim 4
Dependent Claim 43 words
The construction according to claim 2 wherein said nozzle has an intermediate portion tapering from a smaller size at said shoulder to a larger size at said rear end, said tapering intermediate portion restricting movement of said resilient member over said rear end.
Claim 5
Dependent Claim 29 words
The construction according to claim 3 wherein said nozzle is formed with a small opening in said intermediate portion to communicate the interior of said nozzle with the atmosphere.
Claim 6
