Patented July 20, 1943 PAPER ROLL DISPENSER Lester Morton White, Vancouver, British Columbia, Canada, assignor to Morton White & 00., Vancouver, .British, Columbia, Canada I Application October 6, 1941, Serial No. 413,742

4 Claims.- (ol.

My invention relates to improvements inpaper roll dispensers.- The inventionisparticularly adapted for use in dispensers of toilet tissue where a jet of air is relied upon to'throw the free end of the paper] strip over the roll to dispose it in a convenient position for. gripping and severance. I 7

The objects of the invention are to provide means to prevent theremoval of the paper roll as a unit from the mandrel of the dispenser; to

prevent the fitting of a roll of paper to the dispenser, which is different from that provided therefor, and to provide means for locking the roll in position upon the mandrel which will 'not interfere with the efficient functioning of the over the roll.

Fig. 1 is a longitudinal view of the invention with a part of the front wall of the mandrel removed.

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

Fig. 3 is a plan view looking down upon the paper roll locking mechanism.

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

The numeral I indicates generally a support, see Figure 3, which is adapted for attachment to a wall and is provided with an air jet 2. through which is forced a stream of air for displacing the free end of a paper strip from the paper roll 3 indicated in dotted line in Figures 2 and 3.

Extending from the support I is a plate or bracket 4 upon which an oval shaped hollow mandrel 5 is carried. The mandrel is provided with front and rear walls 6 and 1 respectively ancla free end wall 8. The front wall 6 is provided with a finger opening ldsee Figure 3, and shown also in dotted line in Figure 1. The back wall I is provided with horizontal slots II and I2 and the free end wall 8 is provided with a tongue slot l3.

The free end wall 8 has mounted upon it a shelf l5 which supports a paper roll lock mechanism enerally indicated by the numeral [1, which consists of a rocker l8 mounted upon a pivot pin [9. The rocker i8 is provided with a latch bolt at one end and a stop 2| at its opposite end. Intermediate the length of the rocker 13 an aperture 22 is formed at one end of which a clip 23 is struck from a portion of the rocker material. A clip 24 which is preferably struck from the material of the shelf I5 projects upwards through the aperture 22 to the same height and facing in the opposite direction to the clip 23. .These' two clips 23-and 24 are engaged by the free endsof a hairpin spring 25 which is held in position by the pivot pin l9, so that the spring. serves to urge the latch bolt 29 through the rearwall I. and to retract the stop 2| into the body ofth e mandrel 5, as shown in full line in Figure 3.

The shelf i5 is slotted as at 28' and the rocker I8 is provided with a: corresponding end slot 29, both of which slots are in, register when the rocker is in normal position as shown.

, Hingedly m'ountedfon a pivot' 30 from the support I is a clasp 3 having an inturned tongue 32 which is provided .on its under edge with a slot 33 and is bevelled" at its inner end as at 34. The bevel 34 of the tongue serves to de-v press a curvedlatch spring 36 when the tongue enters the slots 28 and 29 and allow its free end to enter the slot 33 and prevent the withdrawal of the tongue and the removal of the clasp 3| from engagement with the free end of the mandrel 5.

The paper roll 3 shown in Figures 2 and 3 entirely in dotted line is perforated in the usual manner along the line 4|, see Figure'Z', to provide for easy severance into strips and is provided with a horizontal slot as at 42, see Figure 3, to receive the latch bolt 20. When one roll of paper has been used, the cardboard core, not shown, upon which such paper is wound is torn off the mandrel 5, thus giving access to the finger opening IE1. By thrusting a finger through the opening It and depressing the spring.36

to release the tongue 32 the clasp 3| may be swung away from the free end wall 8 of the mandrel for the mounting of a new roll. When applying a new roll, it is fitted over the end of the mandrel and thrust endwise into engagement with the bevel of the latch bolt 20, thus swinging the rocker it about its pivot to the position shown in dotted line in Figure 3 and thrusting the latch bolt inwardly through the slot ll. Simultaneously with the entry of the latch bolt 28 into the mandrel, the stop 2| will be projected outwardly through the slot l2. If the paper roll is provided with a slot 42 disposed as shown, as soon as the entering end of the roll reaches the stop 2| the latch bolt 20 will be free to enter the paper slot 42, since the inner end of said slot will then be in register with the latch bolt. When the paper roll is properly disposed as shown the clasp may be returned to position with its tongue 32 extending through the end wall slot I3 and into the slots 28 and 29, thus locking the clasp against Withdrawal and the rocker l8 against movement from its normal position.

The paper roll prevents access to the spring 36 by covering the finger opening l0, thus preventing both the removal of the clasp or the removal of the paper roll.

Should n at empt b d o a n mproperly slotted paper roll to the device, it will be prevented by the stop 2| from being thrust to the inner end of the mandrel and since the slots 28 and 29 will be out of register due to the rocker I8 being in the dotted line position, the clasp 3| cannot be closed or latched in position.

It will be obvious that if it is desired to dis-. pense with the clasp 3| the ring 36 would be extended to enter the slot 29 and so lock the latch bolt 20 in extended position.

What I claim as my invention is:
