Abstract

A two roll tissue dispenser includes mandrels, each supported by an arm having a sleeve portion pivoted on a common axis. Projections on the adjacent ends of the sleeves inter-engage to cause movement of the arm which supports the mandrel in an upper storage position to a lower dispensing position when the mandrel for the lower roll is pushed rearwardly from the dispensing position to an exhausted spool position.

Claims

1. In a toilet paper dispenser having wall means defining a housing and a dispensing opening, the improvement comprising:

(1) first and second mandrels;

(2) support means for supporting the mandrels from a common pivot; and

(3) engagement means on the support means to cause movement of the second mandrel from a storage position to a free swinging position so that the second mandrel can swing about the pivot by gravity to a lower dispensing position upon movement of the first mandrel from a dispensing position to an exhausted core storage position, the engagement means not being engaged when the second mandrel is in its free swinging position.

2. The improvement of claim 1 wherein:

the support means comprises an arm for each mandrel and a sleeve connected to each arm for rotatably supporting said arms on the pivot; and

the engagement means comprises axial projections on adjacent ends of the sleeves which are engageable to cause movement of the arm for the second mandrel in response to movement of the arm for the first mandrel during shifting thereof from its dispensing position to its storage position.

3. The improvement of claim 1 wherein:

the housing comprises (a) a cover including a front wall, top wall and side walls, and (b) a rear wall having upstanding side flanges;

the side walls of the cover are pivotally connected to the upstanding side flanges of the rear wall;

the common pivot comprises a rod connected between the side flanges of the rear wall, and the first and second mandrels and the support means for supporting the mandrels are carried by the rod; and

fresh rolls of toilet paper are loaded axially onto the mandrels over the side flanges of the rear wall upon displacement of the cover therefrom.

4. The improvement of claim 2 including latch means to hold the second mandrel in its storage position comprising a spring element secured to the housing and engageable with a recess in the arm for the second mandrel, the latch means being overcome by manual manipulation of the first mandrel for movement thereof from its dispensing position.
