April 4, 1961 J. YANIELLO ROLL PAPER DISPENSER Filed May 22, 1959 that! INVENTOR. nvous re A4 4 J. W4/V/6L 4 0 a on theiine 33 of Figure l; and

States This invention relates to an improved tear-01f type of dispenser for roll paper, suchas paper towels and the like.

The primary object of the invention is to provide an inexpensive and generally superior device of the kind indicated in which rolls of such as paper towels can be more quickly and easily installed in a secure and protected manner, and wherein the tearing oft of lengths of paper can have no opening effects on components of the device.

Another object of the invention is to provide a device of the Character indicated above which has, in conjunction with its roll-carrying shaft, simple combined means which serves the dual purposes of securing the shaft in place in the device and of fr'ictionally holding, the roll adjacent unwanted free rotation in the device, the said combined meansbeing adjustable to provide different degrees of such frictional holding of the roll.

A further object of the invention is to provide adcompact device of the character indicated above which has means for removably mounting the same on any desired surface, such as in the home, office, or automobile, and which is of uncomplex construction and composed of a small number of simple and easily assembled parts.

' Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for puratent clining and forwardly projecting tearing flange 32 fixed along its depressed forward edge 24. I The flange 32 has a free edge 34 which isformed as a tearing edge and is indented by a central notch 36 which enables grasping and pulling paper left resting upon the flange 32 by the tearing oh of a length of paper along the edge 34.

Fixed on and extending along the elevated rear edge 22 of the lower casing section 14 and projecting radially therefrom is a retaining rib 38 having in its rear side a longitudinal detent slot or groove 40. At locations near to and spaced upwardly and rearwardly from the tearing flange 32 the outer sides of the end walls 18 and-2t have fixed thereon pins 42 and 44, respectively, which are eccentric with respect to the longitudinal axis of the casing 12 and-located on a diameter thereof.

On and preferably integral with the first lower section end wall 18, as seen in Figure 4, is an axial tubular boss 7 4-6 which extends axially outwardly therefrom, and has a closed outer end 48, and an axial bore 50 which opens through the end wall 18 and defines a shaft bearing socket. On and preferably integral with and extending axially outwardly from the second end wall 20 of the lower section 14, is an axial tubular bearing 52 having external screw threads 54. g i

A paper roll shaft 56 extends non-rotatably through the lower casing section 14 and'comprises a smaller diameter cylindrical main portion 58 having a free end 6% to engage conformably in the bearing bore 50 ofthe boss 46, and a relatively short, larger diameter endlpor'tion 62 which extends rotatably and slidably through the bearing 52. The outer end of the enlarged shaft portion 62 has on its outer end a further enlarged knurled cap nut 64 whose internal threads 66 are threadably and removably engaged on the threads 54 of the bearing 52. The meeting of the inward end of the enlarged shaft portion 62 which the main shaft portion 58 defines a shoulder 68, and a relatively large diameterwasher 76 is slidably circum-t posed on the main shaft portion 58 to 'bear against the poses of illustration only,a specific form of'the invention is set forth in detail."

In the drawings: Figure 1 is a perspective view of a device of the invention mounted on a vertical support surface;

t Figure 2 is an exploded perspective viewjof said device; Figure '3 is an enlarged vertical transverse section taken a Figure' 4 is a longitudinal section; taken an thexline 4-4 of Figure 3. g

Referring'in detail to the drawings, wherein, like nuinerals designate likeparts throughout'the several/views,

the illustrated-device 10 comprises,a horizontallyelon- Y gated cylindrical casing 12 which is composed of a rela tively stationary, semi-cylindrical'lower section 14, and a semi-cylindrical, rnovableupper cover-section 16. '1 As shown in ,Figure'3,-the sectionsare separated from each other at points in a planewhich is angled forwardly and downwardly with respect to'the' horizontal; v t 'The lower, relatively stationary casing sectiong14 has fixed circular disc first and second end walls 18- and 20,

respectively; which-have upper halves whichfex tend above the elevated rear longitudinal edge 22 and the depressed forward longitudinaledge l24 of the section 14, and having .fre'earcuate edges 26' upon which the upper sectioni'lfi, '1 rests at its ends; For mounting the device on the surface v section '1 with the hook ml snapped into the retaining I ribgroove ltl'for holding the coversection 16 in clo sed I and secured relation to the lower section 14', Thecover shoulder 68.

As can be seen from Figure 4, aLpaper roll P, of a length to be'accommodated in the lower casing section 14 between its first and second end walls 18 and 2t), and circumposed on the main shaft portion 58, is adapted to be slightly compressed endwise between the first end Wall-18 and the'washer'fli by threading the cap nut 64 inwardly on the bearing 52, until the desired degree of frictional resistance to vagrant rotation of the paper roll in the casing has been; obtained. Theflthreading of the cap nut-64 on the tubular bearing 52 also serves .to assemble the. shaft 56 in the lower casing section 14.

t The upper, movable cover section 16 is devoid of end walls and has on and extending along its elevated rear edge 22 an outstanding and rearwardly' extending hook flange 74 terminating in a resilient hook gageable behind the retaining rib 38 of thelowercasing section 16 is mounted on the lower section M'byfradially [inwardly projecting arms 78, which have holes -80 at their'inward ends, which are located on adiameter of the of a'd esired support, such as a wall28,' the lower section 14 is provided along awhorizontal line spaced below' its elevated rear edge 22, with'mounting means, such as suitably secured longitudinally s'pacedtsuction cups 3);0.v l

The lower section a 14 further comprises a forwardlydeg;

casing 12 and which are snapped over the pins'42, l4v on v the lower casing section end walls 18 and 2t) and which "are also located on a diameter ofthe' casing 12. As an alternative to the hook flange hook 76 being resilient, the same can be rigid and the 'coverlsectionmade suificiently resilient'to' afford the hook the'needed resilient anditensioned engagement with the retaining rib 38 and its detent groove 4!}. I t a As seen'in Figure 3', the depressed forward long'ituedge 82 of the cover section 16"is slightly spaced 76, which is-en upwardly from the tearing flange 32 of the lower section 14, so as to provide a paper guiding exit slot 84, and a fixed paper confining flange 86 on and along the edge 82 extends forwardly therefrom, coextensively with and is parallel Spaced above the tearing flange 32, and has a free edge 88 spaced slightly rearwardly from the tearing edge 34, so as not to interfere with tearing of paper along the edge 34. Removal of the upper casing section or cover section 16, for insertion and removal of a paper roll P in the casing 12, involves forcing the cover section forwardly sufficiently to disengage the hook '76 of the hook flange from the retaining rib 38, as is permitted by the engagement of the arm 78 on the pins 42, 44 and the spacing of the flanges 36, 32, and then snapping the arms 78 off the pins; and these operations are reversed for installing and securing the cover section 16 in place. I

As is apparent from Figure 2, a paper roll P is installed in the casing 12 with the paper coming oif the underside of the roll and passed directly to and through the exit slot 84. Paper is simply pulled off the roll P to the desired length beyond the tearing edge 34 and then pulled downwardly against and along the edge 34 to provide the desired length of dispensed paper. Alternately, the pulled out paper can be pulled upwardly instead, along the free edge 88 of the paper confining flange 86 and torn off along the free edge 88 thereof.

It is believed obvious from the structural formations of the device, as described above, that the same or any of them are susceptible to being made of either metal or molded plastic, or of composition materials.

Although there has been shown and described herein a preferred form of the invention, it is to be understood that the change or changes in the structure of and in the relative arrangements of components thereof are cntemplated as being within the scope of the invention as defined by the claims appended hereto.
