BACKGROUND OF THE INVENTION l Field of the Invention This invention relates to dispensers for rolls of flexible sheet material, such as rolls of toilet paper and paper toweling. Specifically, the invention concerns a dispenser for conventional rolls of flexible sheet material in which a roll is discharged automatically from a dispensing position after a predetermined amount of flexible sheet material has been removed therefrom.
2. Description of the Prior Art A conventional roll of flexible sheet material is generally understoodto be a roll of such material having a tubular core disposed internally thereof, with the ends of the core being coterminous with the ends of the roll. Toilet paper and paper toweling frequently are prepared for marketingv and consumer use in such rolls.
Many attempts have been made to provide a dispenser for conventional rolls of flexible sheet material in which a roll is automatically discharged from a dispensing position after a predetermined amount of material has been removed therefrom. Such dispensers have enjoyed varying degrees of success but have not been widely accepted, principally due to the following drawbacks. First, the prior dispensers of this type are relatively uneconomical to manufacture and maintain. This drawback is the result of employing rather complicated roll supporting and discharging mechanisms which require several machined parts.
A further drawback of the prior dispensers of this type is a lack of sturdiness. This defect permits a roll of flexible sheet material to be removed from a dispenser before the material has been substantially removed therefrom, and also permits a roll to become jammed in the roll supporting and discharging mechanism of the dispenser.
Primarily because of these drawbacks, dispensers for conventional flexible sheet material rolls which automatically discharge a roll after it has been substantially consumed have not been favored by either commercial or private consumers. However, the potential advantages of a dispenser of this type, both to users and custodial personnel, are obvious. Thus, a long-felt need has existed for a dispenser which is economical to manufacture and maintain, and which is rugged enough to withstand the abusive wear encountered in public washrooms.
SUMMARY OF THE INVENTION The dispenser of the present invention offers an optimum solution to the problems associated with the above-mentioned prior dispensers for conventional rolls of flexible sheet material.
Basically described, the dispenser of the invention comprises; a spindle adapted to be inserted through the bore of a conventional roll of flexible sheet material so that the roll is rotatably mounted on the spindle with the ends of the spindle extending axially outwardly beyond the ends of the roll; a pair of substantially horizontally opposed supporting members for engaging the endsof the spindle to thereby rotatably support the roll in a dispensing position between the members, the supporting members being disengageable from the spindle ends upon axial movement of the spindle; means associated with the supporting members for imparting axial movement to the spindle; and means associated with the supporting members for preventing the spindle from moving axially until a predetermined amount of flexible sheet material has been removed from the roll so that after the predetermined amount of material has been removed from the roll, the movement imparting means will move the spindle axially until the ends thereof become disengaged from thesupporting members, whereupon the spindle and the remaining portion of the roll will gravitate automatically from between the supporting members.
Preferably, the dispenser also includes means for storing a reserve roll of flexible sheet material so that after a first roll has been substantially consumed and has been discharged automatically from the dispensing position, the reserve roll will be moved automatically to the dispensing position. This feature extends the service interval of the dispenser, resulting in lower custodial expenses.
Moreover, the dispenser is ruggedly constructed and I is economical to manufacture and maintain, and thus is ideally suited for installation in both public and private washrooms.
With the foregoing in mind, it is an object of the present invention to provide a dispenser for conventional rolls of flexible sheet material in which a roll is automatically discharged from a dispensing position after a predetermined amount of the material has been removed from the roll.
It is also an object of the invention to provide such a dispenser which is economical to manufacture and maintain, and which embodies a rugged structure.
These and other objects of the invention will become apparent upon a considerationof the detailed description of a preferred embodiment thereof given in connection with the following drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT The flexible sheet material dispenser of the invention is designated in the drawings by reference numeral 10.
Dispenser is adapted to rotatably support, in a dispensing position, a conventional roll of flexible sheet material, such as toilet paper roll 12 (FIG. 2). Roll 12 has a tubular cardboard core 14 disposed internally thereof to provide the roll with internal support. Core 14 defines a cylindrical bore 16 extending axially through roll 12 and the ends of the core are coterminous with the ends of the roll.
The internal elements of dispenser 10 include a pair of opposed guide channels 56 and 58. Guide channel 56 is carried by left side plate 24 and comprises a pair of opposed runners 60 and 62 each having an outer flange 64 affixed to side plate 24, a web 66 extending inwardly from side plate 24, and, an inner flange 68. Inner flanges 68 of runners 60 and 62 are spaced apart in opposing relationship so that channel 56 has a substantially C-shaped cross-section, with the opening thereof defining a slot 70 which extends longitudinally of the channel.
Similarly, guide channel 58 is carried by right side plate 26 and comprises a pair of opposed runners 72 and 74 each having an outer flange 76 affixed to side plate 26, a web 78 extending inwardly from side plate 26, and an inner flange 80. Inner flanges 80 are spaced apart in opposing relationship so that guide channel 58 also has a substantially C-shaped cross-section, with the opening thereof defining a slot 82 whichextends longitudinally of the channel.
Operatively communicating with guide channels 56 and 58 are a pair of substantially horizontally opposed supporting members 84 and'86, respectively. Supporting members 84 and 86 engage spindle end portions 50 and 52, respectively, to thereby rotatably support roll 12 in a dispensing position within the dispenser.
Supporting member 84 comprises a pair of brackets 88 (FIG. 4 which are affixed to. inner flanges 68 or runners 60 and 62, within guide channel 56. The upper edges of brackets 88 define a bearing surface 89 comprising two bearing surface sections 90 on which spindle end portion 50 is slideable axially of the spindle.
Supporting member 86 comprises a rib 94 formed in right end plate 26. The upper surface of rib 94 defines a camming surface 94 which is inclined downwardly and inwardly toward supporting member 84. Camming surface 96 engages spindle end portion 52. Due to the inclination of camming surface 96 and the force of gravity acting continuously on spindle42 and roll 12, the camming surface urges the spindle and roll axially of the spindle toward supporting member 84.
The abutment of the inner edge of channel 56 with the end of roll 12 nearest thereto also serves to brake the rotation of the roll and prevent uncontrolled spinning thereof. Also, a flat spring (not shown) may be attached to right side plate 26 which bears against the other end of roll 12 to provide additional'means for urging theroll axially'of spindle 42 towards supporting member 84 and braking the rotation of the roll.
To permit the roll and spindle to move axially of the spindle after the roll has been substantially consumed, the inner edge of channel 56 defines an outwardly extending recess 98 within which core 14 and any remaining portion of roll 12 are accommodable. Recess 98 commences slightlyabove core 14, with the upper extremity thereof being defined by arcuate edges 100 formed in inner flanges 68 of runners 60 and 62. After roll 12 has been substantially consumed, axial movement is imparted to spindle 42 by camming surface 96,
and the spindle, core 14 and the remaining portion of roll 12 move axially of the spindle toward supporting members 84 with core 14 and the remaining portion of the roll being accommodated within recess 98. When this occurs spindle end portion 50 slides axially off of bearing surface 89 and spindle end portion 52 slides inwardly and downwardly off' of camming surface 96 (FIG. 3). The spindle, core and remaining portion of the roll then gravitate downwardly from between supporting members 84 and 86, with intermediate spindle portion 48 moving along slot 82.
Preferably, guide channels 56 and 58 are long enough to accommodate at least two rolls therebetween simultaneously with a first roll being disposed in the dispensing position between supporting members 84 and 86 and a second roll being disposed above the first roll in a reserve position (FIGS. 1,2 and 6). Thus, after the first roll has been discharged automatically from the dispensing position, the second roll will move downwardly automatically between the guide channels until the end portions of the spindle on which the second roll is mounted have engaged supporting members 84 and 86. This feature is particularly advantageous for public washroom installations, where the dispensers are serviced at regularly established intervals. The provision of a reserve roll in each dispenser reduces the frequency with which the dispensers must be serviced and therefore increases the service interval, with a resulting decrease in custodial expenses.
When the dispenser is serviced, the spindles 42 which have been automatically discharged from between supporting members 84 and 86 are removed from between the lower ends of guide channels 56 and 58, and the cores 14 and remaining roll portions mounted thereon removed from the spindles. Fresh rolls 12 are then mounted on the spindles and the spindles reinserted into the upper ends of the guide channels to provide a fresh supply of toilet paper for the dispenser.
As will be apparent, dispenser is not only economical to manufacture and maintain, having no machined parts and only one moving part, i.e., spindle 42 and, but also embodies a rugged structure which is able to withstand the abusive wear encountered in public washrooms. The dispenser is thus ideally suited for installation in both public and private washrooms.
While the foregoing constitutes a detailed description of a preferred embodiment of the invention, it is recognized that various modifications thereof will occur to those skilled in the art. Therefore, the scope of the invention is to be limited by the scope of the appended claims.
