3 Claims.

My invention relates to improvements in paper roll dispensers.

The invention as here shown is adapted for the use of oval paper rolls on dispensing devices of the bellow type in which a force of air is developed for lifting the free edge over the top of the roll and allowing it to come to rest hanging below the roll to provide easy access thereto.

The objects of the invention are to provide means for locking the paper roll in position upon the mandrel and to prevent the removal of said roll from the mandrel until it is unwound in the ordinary course of use.

Fig. 1 is a longitudinal sectional view of the invention taken on the line ll of Figure 2.

Fig. 2 is a transverse sectional view taken on the line 2 2 of Figure 1.

Fig. 3 is a plan view, on the line 3-3 of Fig. 1.

In the drawing like characters of reference indicate corresponding parts in each figure.

The numeral I, see Figure 3, indicates a base adapted to be secured to a Wall surface. From one side of the base I a bracket 2 extends which forms at its outer extremity an end Wall 3 of a mandrel generally indicated by the numeral 4.

The mandrel A is in the form of an oval cylinder having front and rear walls 6 and l and is fitted with a free end wall 8. The front wall 6 is provided with a finger opening 9 which is indicated in Figure 1 in dotted line and elsewhere in full line. Extending longitudinally of the mandrel 4 are leaf springs l i and I2.

The spring [I is provided at its outer end with a latch bolt is which normally extends through an appropriate aperture formed in the rear wall I and is provided adjacent its point of attachment with an aperture M which serves to weaken the spring at that point, so that when the latch bolt is moved into retracted position, a shown in dotted line in Figure 3, the maximum flexure will take place within the longitudinal length of the aperture. Coincidentally the change in the angle of the latch bolt I3 when being moved from normal position to retracted position will .be considerably less than that which would prevail if the entire overhang length of the spring were flexed equally.

The spring [2 is upturned at its free end to form a catch [5, the purpose of which will hereinafter appear. Hingedly mounted from the side of the base is a keeper l6 having a tongue I! which normally projects through an appropriate opening I 8 in the end wall 8 of the mandrel. The tongue I1 is provided with a slot I9 into which the catch N3 of the spring 12 is adapted to enter to prevent the withdrawal of the tongue I! from the mandrel 4. It will be noted that the free end of the tongue I! when in normal position, see Figure 3, bears upon the free end of the spring II to prevent the latch bolt 13 fro being thrust back into the mandrel.

The paper roll 20 which is indicated in Figures 2 and 3 in dotted line, is provided with an aperture 2!, see Figure 3, along its normal line of perforation, not shown.

In fitting a paper roll to the dispenser, the keeper i6 is thrown back and the paper roll started onto the free end of the mandrel 4, the latch tongue i3 is pressed back to the position shown in dotted line in Figure 3 and the roll pushed further onto the mandrel until the latch tongue is projected into its aperture 2|, which looks the paper roll in position with the roll covering the finger opening. When the keeper I6 is moved into position its tongue becomes engaged by the catch l5 of the spring l2, thus looking the keeper in normal position and the latch bolt [3 in normal or extended position in the aperture 2| of the paper roll 20.

bracket extending from the base, a mandrel adapted to receive a paper roll, said mandrel being connected at one end to the bracket, a keeper having a tongue at one end, a latch bolt normally projecting outwardly through a side of the mandrel, said latch bolt being mounted upon a leaf spring, said leaf spring being attached to a part of the mandrel, said tongue being adapted to enter the mandrel and engage the spring to prevent the retraction of the latch bolt, and

means 'to prevent the withdrawal of the tongue H from themandrel.

2. A paper roll dispenser comprising a base, a bracket extending from the base, a mandrel adapted to receive a paper roll, said mandrel being connected at one end to the bracket, a.

keeper having a tongue at one end, a latch bolt normally projecting outwardly through a side of the mandrel, said latch bolt being mounted upon a leaf spring, said leaf spring being at-;

tached. to a part of the mandrel, said tongue being adapted to enter the mandrel and engage extending longitudinally within the mandrel, one of said springs being provided with a latch bolt and being adapted to normally extend said latch bolt outwardly through a side of the mandrel, said tongue having a slot and being adapted to enter the mandrel and overlie one end'of the latch bolt, said second spring having a catch at its free end adapted to enter the slot of the tongue.
