Portions 32 and 34 are integrally joined at the upper extremity of one of the cross-sectional legs of portion 32 and one of the cross sectional extremities of portion 34.
  • each of the members also may include a lower flange 36 to facilitate attachment of the members to the respective side panels of cabinet 12.
  • Members 24 and 26 preferably are made from integral sheet metal blanks by stamping.
  • the supporting members are adapted to rotatably support a roll 38 of flexible sheet material, such as a roll of paper toweling, in a dispensing position therebetween.
  • Roll 38 is of the type described in Jespersen U.S. Pat. No. 3,438,589 with respect to the embodiment shown in FIGS. 1-4 of the patent.
  • the roll includes a centrally disposed core 40 onto which flexible sheet material, such as paper toweling, is wound.
  • Disposed adjacent the ends of roll 38 and inserted into the ends of core 40 are a pair of trunnions 42 and 44.
  • Trunnion 42 comprises an annular, outer, flange portion 46, an annular, inner, shaft portion 48 and an annular web 50 joining portions 46 and 48. Portions 46 and 48 and web 50 define a recess 52 opening axially outwardly from the adjacent end of roll 38.
  • trunnion 44 comprises an annular, outer, flange portion 54, an annular, inner, shaft portion 56 and an annular web 58 joining portions 54 and 56. Portions 54 and 56 and web 58 define a recess 60 opening axially outwardly from the adjacent end of roll 38.
  • Shaft portions 48 and 56 extend axially outwardly beyond the ends of roll 38, and are adapted to be rotatably engaged by supporting members 24 and 26, respectively.
  • shaft portion 48 is adapted to be engaged by the outer surface of the shorter cross-sectional leg of lower portion 30. This surface is inclined laterally downwardly and inwardly toward supporting member 26, as shown in FIG. 1, and defines a camming surface 62.
  • Camming surface 62 comprises a means for biasing roll 38 axially of the roll toward supporting member 26. This result is obtained due to the gravitational force acting on the roll. The gravitational forceproduces a reaction force which is applied to the roll by surface 62 and which includes a force component extending axially of the roll in the direction of member 26.
  • shaft portion 56 is adapted to be engaged by the inner surface of one of the crosssectional legs of portion 32.
  • This surface extends substantially laterally horizontally, as shown in FIG. I, and defines a bearing surface 64.
  • Surface 64 has a notch 66 therein which is of a greater width than the combined thickness of flange portion 54 and core 40.
  • notch 66 is spaced from one end of member 26 a distance less than the inside diameter offlange portion 54. However, the notch is ofa lesser width than the outside diameter of shaft portion 56. The purpose of notch 66 is described below.
  • Dispenser also includes means for urging roll 38 radially of the roll toward the end of member 26 proximate notch 66.
  • Such means are comprised by supporting members 24 and 26, including surfaces 62 and 64, respectively, being inclined longitudinally downwardly, as shown in FIGS. 2 and 3, with the end of member 26 proximate notch 66 being the lower end of that member.
  • the dispenser also includes means for preventing roll 38 and trunnions 42 and 44 from shifting axially of the roll until the flexible sheet material has been substantially exhausted from about the roll.
  • Such means is comprised by the outer extremity 63 of the upper cross-sectional leg of portion 32. As shown in FIG. 1, the left end of roll 38 abuts extremity 63 when the roll is disposed in the dispensing position.
  • flange portion 54 and core 40 are received within notch 66 and flange portion 54 is received beneath the upper cross sectional leg of portion 32, while the section of supporting member 26 between the notch and the proximate end of the supporting member is received within recess 60 below shaft portion 56, as shown in FIG. 4.
  • the axial shifting of the roll and trunnions results in shaft portion 48 becoming disengaged from supporting member 24, whereupon the roll and trunnions gravitate downwardly out of the dispensing position.
  • the distance between the end of member 26 proximate notch 66 and panel 20 is less than the outside diameter of flange portion 54, as shown in FIG. 4. Therefore, the trunnions are prevented from rolling off the lower ends of the supporting members so that the roll and trunnions may be discharged from the dispensing position only upon the abovedescribed axial shifting thereof.
  • panel 20 and extremity 63 serve as braking means for minimizing uncontrolled spinning of the roll.
  • the flexible sheet material is removed from about the top of roll 38, as shown in FIGS. 2 and 3.
  • the material passes between the front of the roll and panel 20, and downwardly out of the dispenser through the open bottom thereof.
  • the outwardly flared lower portion of panel 20 serves as a means for guiding the material from the dispenser and holds the material while it is being torn along the lower edge of such portion.
  • the framework of dispenser 10 also includes a pair of guide channels 68 and 70 positioned above supporting members 24 and 26, respectively.
  • the guide channels each have a substantially U-shaped transverse cross section for guiding the trunnions to the supporting members, to thereby guide the roll into the dispensing position between the supporting members.
  • guide channel 68 is adapted to engage shaft portion 48
  • guide channel 70 is adapted to engage shaft portion 56.
  • Shaft portions 48 and 56 have different diameters and channels 68 and 70 have different cross-sectional widths corresponding to the diameters of portions 48 and 56, respectively.
  • rolls 38 are inserted into the dispenser through the open bottom thereof.
  • the upper portions of the rear cross-sectional legs of channels 68 and 70 are cut away at 65 and 67, respectively, to permit a roll to be inserted between the channels fromthe rear thereof.
  • the channels are long enough to accommodate therebetween two unused rolls of relatively small diameter or a single unused roll of relatively large diameter, such as roll 38.
  • the lower portions of the rear cross-sectional legs of channels 68 and 70 are also cut away at 69 and 71, respectively, as shown in FIG. 1.
  • Supporting members 24 and 26 include restraining flanges 72 and 74, respectively, integrally formed at the upper ends of camming surface 62 and bearing surface 64, respectively, for preventing the trunnions from being pushed off the upper ends of the supporting members.
  • Lower portion 34 has a notch 76 therein, as shown in FIGS. 2 and 4, which cooperates with notch 66 to permit the roll and trunnions to be shifted axially of the roll toward supporting member 26 after the roll has been substantially consumed.
  • cabinet 12 may have a closed or partially closed bottom and an openable top, front or side panel to permit the insertion of rolls into the dispenser.
  • means other than camming surface 62 could be employed for biasing the roll and trunnions axially of the roll toward supporting member 26, such as a small spring afiixed to right side panel 16.
  • means other than the longitudinal downward inclination of the supporting members could be employed for urging the roll radially thereof toward the end of member 26 proximate notch 66, such as a small spring affixed to rear panel 14. Therefore, the scope of the invention is to be limited solely by the scope of the appended claims.
  • a framework including a pair of substantially horizontally opposed supporting members for rotatably engaging said trunnion shaft portions to position the roll for rotation about a substantially horizontal axis between said members to thereby rotatably support the roll in a dispensing position, one of said members defining a bearing surface engageable with the shaft portion of one of said trunnions and having a notch therein of a width greater than the thickness of the flange portion of said one trunnion, said notch being spaced from one end of said one member a distance less than the inside diameter of said one trunnion flange portion;
  • biasing means is comprised by a camming surface defined by said other supporting member and engageable with the shaft portion of said other trunnion, said camming surface being inclined downwardly and inwardly toward said one supporting member.
  • said framework further includes a cabinet enclosing said supporting members, said cabinet including a front panel; and wherein said means for preventing the trunnions from rolling off the lower ends of the members is comprised by said front panel being spaced outwardly from said one member end a distance less than the outside diameter of said one trunnion flange portion.
  • said framework further includes a pair of guide channels disposed above said supporting members and being engageable with said trunnion shaft portions upon the insertion of a roll into the device for guiding the trunnions to the supporting members'to thereby guide the roll to said dispensing position.
  • said means for preventing axial shifting of the roll and trunnions is comprised by a portion of said one supporting member, said one member portion being adapted to engage the end of the roll adjacent said one member when the roll is disposed in said dispensing position.
