Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
187 words
A dispenser for at least two rolls of paper including a shell, a compartment for each of said rolls in said shell, a first window exposing one of said compartments, a second window exposing another of said compartments, a control member pivotally mounted on said shell, means yieldingly urging a control finger portion of said control member against the paper on a roll in one of said compartments said member including a latch finger extending into a central area between said windows, a door slidable between a first position closing the window of said other compartment and exposing the window of said one compartment, and a second position closing said window of said one compartment and exposing the window of said other compartment, said latch finger being positionable in engagement with said door to hold the same in said first position, said yielding means urging said member and latch finger into a position disengaging said latch finger from said door to permit said door to move to said second position in response to depletion of paper from said roll in said one compartment below a predetermined level.
Claim 2
Dependent Claim
187 words
A dispenser for at least two rolls of paper including a shell, a compartment for each of said rolls in said shell, a first window exposing one of said compartments, a second window exposing another of said compartments, a control member pivotally mounted on said shell, means yieldingly urging a control finger portion of said control member against the paper on a roll in one of said compartments said member including a latch finger extending into a central area between said windows, a door slidable between a first position closing the window of said other compartment and exposing the window of said one compartment, and a second position closing said window of said one compartment and exposing the window of said other compartment, said latch finger being positionable in engagement with said door to hold the same in said first position, said yielding means urging said member and latch finger into a position disengaging said latch finger from said door to permit said door to move to said second position in response to depletion of paper from said roll in said one compartment below a predetermined level.
Claim 3
Dependent Claim
47 words
The structure of claim 1 wherein said one compartment is beneath said other compartment and said latch finger engages a central underside of said door whereby said door moves by gravity to said second position in response to depletion of paper from said roll below said level.
Claim 4
Dependent Claim
83 words
The structure of claim 1 wherein said latch finger is pivotally mounted on said member and said latch finger and said door include camming surfaces whereby movement of said door from said second to said first position moves said latch finger portion in one direction out of its door-retaining position upon passage therebeyond of said door and movement of said door in response to said depletion of said paper moves said latch finger portion in the opposite direction out of its door-retaining position.
Claim 5
Dependent Claim
30 words
The structure of claim 3 wherein said latch finger is pivoted adjacent its rearmost end to said member, said latch finger returning to said retaining position in response to gravity.
Claim 6
Dependent Claim
43 words
The structure of claim 1 wherein said control member includes an arm portion disposed in substantially parallel relationship to a roll of paper in said one compartment, said latch finger portion being pivoted on and extending beyond said arm portion in parallel therewith.
Claim 7
Dependent Claim
27 words
The structure of claim 1 wherein said control member is pivoted about an axis normal to the axis of a roll of paper in said one compartment.
Claim 8
Dependent Claim
113 words
In a dispenser for rolls of paper, a shell, a compartment for each roll of paper in said shell, a door movable in said shell to cover one compartment and expose another compartment, a control member for said door, said control member having a portion engaging the paper on a roll in said one of said compartments to hold said member in a first position and means yieldingly urging said member into a second position in response to depletion of paper from said last-named roll below a predetermined level, and camming portions on said member and door whereby said door may be moved past said arm in one direction without displacing said member.
Claim 9
Dependent Claim
113 words
In a dispenser for rolls of paper, a shell, a compartment for each roll of paper in said shell, a door movable in said shell to cover one compartment and expose another compartment, a control member for said door, said control member having a portion engaging the paper on a roll in said one of said compartments to hold said member in a first position and means yieldingly urging said member into a second position in response to depletion of paper from said last-named roll below a predetermined level, and camming portions on said member and door whereby said door may be moved past said arm in one direction without displacing said member.
Claim 10
Dependent Claim
32 words
The structure of claim 7 wherein said member includes an arm portion extending in parallel with said last-named roll and a latch finger pivoted adjacent the distal end of said arm portion.
Claim 11
Dependent Claim
38 words
The structure of claim 8 wherein said member is pivoted about an axis normal to the axis of said last-named roll and said latch finger is pivoted about an axis normal to the axis of said last-named roll.
Claim 12
Dependent Claim
63 words
The structure of claim 8 wherein said arm portion and latch finger are held in a plane inclined with respect to the axis of said last-named roll and inclined upwardly toward said door in door-latching position, whereby said arm portion and latch finger move laterally and downwardly with respect to said door in response to said depletion of paper from said last-named roll.
Claim 13
Dependent Claim
72 words
The structure of claim 8 characterized by and including inclined, curved camming surfaces on said latch finger and said door, a first set of said camming surfaces being engageable in response to movement of said door in one direction past said latch, a second set of said camming surfaces being engageable to hold said door in one of said positions and relatively slidable during movement of said member toward said second position.
Claim 14
Dependent Claim
40 words
The structure of claim 7 characterized by and including an abutment ear carried by said control member and positioned for contact with a portion of said shell when said control member is moved against the action of said yielding means.
Claim 15
Dependent Claim
117 words
The structure of claim 7 wherein said door includes a horizontally positioned bottom flange, a pair of recesses positioned on opposite sides of the center of said flange and said control member includes a latch finger pivoted thereto and engaging said flange between said recesses when said door is in one position, said camming portions including a camming abutment carried by said door between said recesses and camming surfaces on said abutment and said latch finger whereby movement of said door toward said position cams said latch finger into alignment with one of said recesses and movement of said control member toward its second position moves said latch finger into alignment with the other of said recesses.
Claim 16
Dependent Claim
33 words
The structure of claim 13 wherein the portion of said latch finger engaging said central flange portion when said door is in said one position is downwardly inclined from said central flange portion.
Claim 17
Dependent Claim
60 words
The structure of claim 14 wherein said control member and latch finger are held in a position inclined with respect to said flange when said control member is held in its first position, whereby movement of said control member toward its second position moves said inclined latch finger surface in a downwardly inclined path toward alignment with said second recess.
