The purpose of this ar- 55 rangement has been previously mentioned, and it can be seen in Figure 1 that the paper after being fed out tends to curl as indicated at 40. The paper is thus spaced as at 4| away from the front wall 2 so that its lower edge portion can be easily grasped. If the web 36 came off of that side of the roll which is nearest the back wall 42 of the cabinet, the curl after exit would be in a direction opposite to that shown at 40, in which case the bottom edge 45 of the paper would be against the outer surface of the wall 2 so that it would be difficult to grasp.

An important feature of this invention is the provision of means on the roll, and on a mount or support therefor, which prevents wrong placement of the roll on the support. Referring to Figure 2, one form of the invention comprises a support made of sheet metal and having arms 5|, 52, bent up from a connecting portion 50. Each arm is pivoted as at 53 to a corresponding plate l1, so that the support can be swung outwardly to a point accessible for loading, see dot and dash lines of Figure 1. The inward movement of the frame is limited by stop pins 55.

Referring now to.Figures 2, 3 and 7 the roll 35 has a core 60' of paper which is preferably hollow, and one end of the core has secured thereto a series of coupling projections. The projections are formed by suitably slitting the end of a metal tube GI, and said projections are indicated at 62 and in this instance there are four. Portions 64 of the metal at points between the projections are bent around the end of the core as clamps, thus securing the tube 5| in the core 60. On the arm 5| is a disc 66 rotatably held on pin 61 suitably riveted to the arm. This disc has what may be termed recesses, 68, 69 arranged in pairs diametrically related to one another. These recesses are herein constituted by openings and notches. In Figure 4 the recesses 68 are constituted by openings, which extend entirely through the disc and the recesses 59 are constituted by notching the edge of the disc. In Figure 10 these recesses are formed by punching openings 10 in the disc 66.

On the arm 52, see Figure 7, is a projection 15 which is formed from a plate by punching to provide fingers 16 which are bent to form the hollow square shown in Figure 8. This element 15 is pivoted to the arm 52 as at 11, and the corners l8 loosely engage the inner surface of the core 60. By means of the elements 56 and 15 the core and the supply roll upon it are ro tatably mounted, and it is seen that itis impossible to mount the roll unless the respective elements of the mounting means are in the exact cooperative relation shown. Although the speciflc mounting means is claimed, there is no intention to limit the invention entirely to the construction because I believe myself the first to provide means for preventing wrong placement of the roll for the purpose disclosed.

In Figure 9 the element 66 only differs from that of the element 66 in that recesses are all made by punching openings in the disc. It is to be understood that there may be only two of these recesses instead of four as shown in Figures 4, and 10, respectively. In this case also the arms 5|, 52 are separately pivoted as at to the plates I1 and the arm 52 has a plug 8| pivoted as at 82 and having a flange 83 which engages the edge or end of the core 60.

It is noted that the arms 5| and 52 are housed in recesses 84 of the plates I 1'. As shown in Figure 10 the bottom portion 85 of the recess formsa stop for limiting the inward movement of the arm, and the forward portion 86 of the bottom of the recess forms a stop for limiting the outward movement.

Whatever the construction of the cooperative means carried respectively by the support and core, it is understood that broadly they are so constructed that mounting can be accomplished only in one way, that is, when the roll is placed as has been previously described.

Various changes in the construction can be made without departing from the broad idea of forced proper placement to prevent less accessible positioning of the paper after feed-out.

I claimas my invention:

1. A paper cabinet having a front wall having a delivery opening, a pair of feed rolls with which the paper has substantially only a line contact, means by which the paper is guided after leaving said feed rolls, and a supply roll, said feed rolls, guiding means and supply roll being so related that that face of the paper which was inside when on the roll faces toward the user and away from said front wall of the cabinet after passing through the delivery opening, whereby the curling tendency'of the paper resultant from its original roll formation is utilized to maintain the projected portion of the paper spaced from the wall to facilitate grasping, said supply roll having a core, and means for detachably mounting said core, said means being so formed that cooperation for mounting cannot take place unless the supply roll is related to said feed rolls and guiding means in the manner aforesaid.
