HUNT, OF NORTH VANCOUVER, BRITISH COLUMBIA, CANADA, AssieNon '10 INTERNATIONAL AIREX L'rn, OF VANCOUVER, BRITISH COLUMBIA, CANADA PAPER ROL Application. filed November 4,1927. SerialNo. 231,065

My invention relates to improvements in paper rolls, which is particularly adapted for use with toilet paper dispensing devices where the roll is adapted to be applied to a form which is supported at one end. The

' per roll perforated transversely in any suitable manner and provided with a transverse slot extending inwards from one marginal edge and having means adapted to co-oper ate with a tongue upon the paper dispensing device to hold the roll against endwise re moval therefrom, as will be more fully described in the following specification, in which V Fig. 1 is a' general view of a paper dispensing device fitted with a roll paper looking tongue.

Fig. 2 is a fractional plan View of a paper roll showing the invention.

Fig. 3 is a view showing the application of the paper roll into engaging contact with the locking tongue of the dispensing device.

Fig. 4 is a fractional view showing a modified form of locking slot.

Fig. 5 is a fractional view showing the engagement between the locking tongue and the modified form of slot shown in Figure 4.

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

The numeral 1 indicates generally a paper dispensing device of any suitable kind having a base panel 2 and a side panel 3 from which an oval form 4 extends laterally for the purpose of supporting the perforated paper roll. Extending from the side panel 3 and in contact with the form 4 is a looking tongue generally indicated by the numeral 5 which is preferably formed from a strip of sheet material having a shank 6 terminating at its outer end in a hook shaped member 7 having a bill 8 extending towards the side panel 3 and-at an appreciabledistance to one side of the longitudinal axis of the shank 6.

The numeral 9 indicates generally a paper roll perforated transversely as at 10 in any suitable manner in order that the roll may be freely tornprogressively into separate lengths or sheets. elongated slot 11 of lesser'width than the hook shaped member 7 of the locking tongue 5 is cut through the several layers at one side only of the roll and is provided at its inner end with a key portion 12; the outer side 13 of which is disposed at a right angle to the longitudinal axis of the 'slot' 11.

In the modification shown in Figures 4 and 5inlieu of providing a key portion to the slot 11 I form an incision 14- at'a right angle to the slotand to one side thereof. I

Having thus described the several parts of my invention I will now briefly explain its use. A

7 When placing a paper roll, such as is shown in Figures 2 and 3, upon the form 4 of the paper dispenser 1, the slot 11 of the roll is so disposed as to register with the locking tongue 5 and the roll moved upon the form in the direction of the side panel 3. As the tongue enters the slot 11 the shank 6 will bear against one side thereof and the bill of the hook shaped member 7 will engage the other side and in so doing will cause the several layers forming the roll to curl upwards as shown in Figure 3, thus facilitating the entry of the locking tongue and the disposition of the hill 8 within the key portion 12 of the slot. When the roll is pushed into its ultimate position in substantial contact with the side wall 3 of the dispenser, that portion of the layers of paper which was displaced by the passage of the bill 8 into the slot resumes its normal position. Should any attempt be made to withdraw the roll from the form, the bill 8 of the tongue 5 would engage the outer side 13 of the key portion 12 to prevent its removal therefrom.

Where a roll is used similar to that shown At one end of the roll an in Figures 4 and 5, the procedure would be 14 and a permanent slight displacement of the layers of paper on the other side of the incision would be produced.

What I claim as my invention is:

1. In a paper roll adapted for mounting on a paper dispensing device, :said roll :having an open ended slot .iextending transversely thereof and means adjacent the inner end of the slot capable of being engaged by a part of the dispensing device "on "attempt being madetowithdrawthe rollth'erefrom.

2. In a paper roll, said roll having a transverse slot extending inwardly from one side edge thereof, said slotwbeing widerrat its'inner end than at its outer end. 7
