A coffee filter dispenser to dispense individual coffee filters of the cup type from a stack, comprising a housing having a bottom wall, side walls, a rear wall and an open front wall, dimensioned to receive a stack of cup type coffee filters therein facing upside down. A friction bar is positioned to slide on tracks secured to the side walls, first in a rearward direction in which it makes initial contact with the uppermost filter in the stack to slightly raise and loosen it and then in the foreword direction to eject the loosened filter from the stack and from the dispenser. The friction bar is normally biased to its forward position by a pair of coil springs connected to respective end regions of the bar and to respective brackets extending forwardly from the forward edges of the side walls. A wire or thin cable connects the friction bar to a manually operated vertical slide mechanism adjacent the rear wall of the housing, which draws the friction bar rearwardly to initially loosen the top filter when the slide mechanism is pushed downwardly. When downward pressure on the slide mechanism is released, the springs snap the friction bar back in the forward direction to eject the initially loosed top filter with which it is in frictional engagement. A laterally extending spacer bar carried by the track members toward the rear of the housing is provided for the cable to travel over as it pulls the friction bar rearwardly, the spacer bar keeping the cable from pressing down on the stack of filters.
A coffee filter dispenser to dispense individual coffee filters of the cup type from a stack of such coffee filters comprising a chamber in which to receive a said stack of said coffee filters in a position wherein said cup type coffee filters in said stack are facing upside down, said chamber having a bottom wall on which to place said stack of cup type filters facing upside down, said stack having an uppermost cup type filter thereon facing upside down, said uppermost cup type filter having a bottom cup wall facing upwardly from said stack, initial loosening means positioned to engage said uppermost cup type filter in said stack to initially loosen said uppermost cup type filter from said stack, said initial loosening means being non-adherent, and ejection means positioned to engage and slidably eject said uppermost cup type filter from said stack after it has been initially loosened by said initial separating means.
A coffee filter dispenser to dispense individual coffee filters of the cup type from a stack of such coffee filters comprising a chamber in which to receive a said stack of said coffee filters in a position wherein said cup type coffee filters in said stack are facing upside down, said chamber having a bottom wall on which to place said stack of cup type filters facing upside down, said stack having an uppermost cup type filter thereon facing upside down, said uppermost cup type filter having a bottom cup wall facing upwardly from said stack, initial loosening means positioned to engage said uppermost cup type filter in said stack to initially loosen said uppermost cup type filter from said stack and ejection means positioned to engage and eject said uppermost cup type filter from said stack after it has been initially loosened by said initial separating means, wherein said initial loosening means includes a friction engaging member movable in a first direction to engage and initially loosen said uppermost cup type filter in said stack, said ejection means includes said friction engaging member movable in a second and different direction to engage and eject said initially loosened cup type filter from said stack, including operating means to move said friction engaging member in said first and second directions, wherein said operating means is manually operable and includes a handle for a user to manually grasp and move said friction engaging member in at least one of said first and second directions, wherein said operating means is normally biased toward at least one of said first and second positions and includes a biasing member to bias said operating means toward said one of said first and second directions, wherein said friction engaging member comprises an elongated rod positioned laterally across said chamber in position to frictionally engage a portion of said uppermost cup type filter in said stack, said chamber having a rearwardly facing wall and a forwardly facing open wall, said elongated rod being moved rearwardly in the direction of said rearwardly facing wall when moved in said first direction and being moved forwardly in the direction of said forwardly facing open wall when moved in said second direction, wherein said elongated rod includes a friction enhancing member positioned thereon for frictional engagement with a portion of said uppermost cup type filter in said stack, wherein said chamber includes first and second spaced apart side walls extending between said rearwardly facing wall thereof and said forwardly facing open wall thereof, a first track member along said first one of said side walls extending longitudinally between said rearwardly and forwardly facing walls of said chamber and facing inwardly thereof, a second track member along said second one of said side walls extending between said rearwardly and forwardly facing walls of said chamber and facing inwardly thereof toward said first track member, said laterally positioned elongated rod having each opposite end received in a respective one of said first and second track members for sliding movement therein in said first and second directions, wherein said operating means includes an operating mechanism positioned adjacent said rearwardly facing wall of said chamber and inwardly thereof, said operating mechanism including said handle, said handle extending through an opening in said rearwardly facing wall, said operating mechanism including a vertically extending guide bar, a slide member mounted for reciprocating movement on said vertically extending guide bar between an uppermost position and a lowermost position and movable in at least one direction therebetween by said handle, an elongated connecting line connected to said slide member at one end and connected at its other end to said laterally positioned elongated rod, said connecting line drawing said rod rearwardly in said first direction to initially loosen said uppermost cup type filter in said stack when said handle moves said slide member downwardly to its said lowermost position, said biasing member including a spring connected at one end to said laterally positioned elongated rod and connected at its other end to a bracket projecting forwardly of said chamber to bias said rod forwardly in said second direction to engage and eject said initially loosened uppermost cup type filter from said dispenser.
