3,473,749 R0111. DISPENSING MEANS Donald E. Rogers, 975 Fairfax, Birmingham, Mich. 48009 Continuation of application Ser. No. 685,018, Nov. 22, 1967. This application Feb. 3, 1969, Ser. No. 800,338 Int. Cl. B6511 49/18 US. Cl. 242-5553 11 Claims ABSTRACT OF THE DISCLOSURE There is provided an improvement in dispensing means of the type wherein a roll of material is wound about a central core, such as toilet paper, paper towels or the like, and wherein such supply rolls are mounted in receptacles. The improvement includes a housing adapted to be received within the supply roll, the housing having a telescopically received end member with a pivot shaft extending outwardly thereform and receivable in the receptacle. A small motor is mountedin the housing and is rotatable therewith, the motor having a shaft extending outwardly therefrom and being receivable in the receptacle. Electric supply means, such as a battery, is also received in the housing and suitable electrical connections are made through the motor. Friction means mounted on the motor shaft and engageable with the receptacle maintain the motor shaft stationary so that the motor, power means and housing rotate therearound. A suitable lever is mounted for movement into engagement with contact rings on the motor to complete the electric circuit through the power supply means, thus actuating the motor and causing the entire assembly to rotate.

This application is a continuation of application Ser. No. 685,018 filed Nov. 22, 1967, and now abandoned.

This invention relates to dispensing means, and more particularly to a motor driven dispensing device for a supply roll of material of the type wound around a central core.

There are many instances where flexible materials of one kind or another are wound in the form of a coil or roll for dispensing as needed, such roll being mounted in a receptacle or holder for storage and use as necessary. Typical of such materials are paper towels and toilet paper, both of which are normally wound about a cardboard cylinder. The cylinder is received in a suitable receptacle or on a suitable spindle to permit dispensing of the paper as required by the user. It is generally the case that as the material is needed, the user pulls the free end thereof to unreel a suflicient amount from the supply roll and removes that amount from the roll.

Devices have been provided in the past to mechanically rotate such dispensing supply rolls, usually in the form of an electric motor, driving gears and the like, upon response to a closing of a switch or through other means of connecting the motor to a supply power circuit. Such past devices are, however, complicated and cumbersome, requiring a large number of parts in order to accomplish the intended purpose. The motor is normally mounted in some stationary position removed from the dispensing roll, and rollers, gears, levers or the like, must properly connect the power output from the motor to the dispensing roll. Consequently, numerous disadvantages appear, particularly in the number and arrangement of the parts and the size of the power supply necessary to create the intended rotation, along with the numerous points of wear and possible breakdown in such complicated devices. In addition, such devices are seldom adaptable to present dispensing roll receptacles,

ited States Patent f 3,473,749 Patented Oct. 21, 1969 requiring extensive and expensive construction when mounting such device for convenient use by the user.

The device in which this invention is embodied comprises, generally, a dispensing roll for a supply roll which has mounted therein an electric motor. The motor shaft extends outwardly therefrom, such shaft being receivable in a receptacle. At the opposite end of the spindle is a telescoping end member having an outwardly directed shaft portion, also receivable in the receptacle. A power supply means is further mounted in the housing and connectable to the motor where, upon actuation, the entire housing, motor, supply means and the like will rotate with the dispensing roll, causing the material to dispense from the supply roll. Suitable means are provided to maintain the motor shaft in a nonrotatable position so that the entire assembly will rotate therearound. A lever, or the like, may be mounted on the motor shaft and actuated to operate the power supply means, thus causing dispensing rotation.

A device so constructed is extremely simple to manufacture and produce and is easily adaptable for acceptance in various types of supply rolls. Since the entire assembly is self-contained, it may be easily designed as to be received in present supply roll receptacles, so as not to require remodeling or reconstruction at the location where such device is to be used. Very few parts are required, thus eliminating almost entirely the wear and breakdown problems. The overall result is an extremely economical device to positively rotate a supply roll in response to lever action, and one that may easily be mounted in existing facilities.

These and other advantages will become apparent from the following description, used to illustrate a preferred embodiment of the invention when taken with the accompanying drawings in which:

FIGURE 1 is an elevational view, with parts broken away and in section, of a dispensing device mounted in a receptacle and illustrating the position of the various parts;

FIGURE 2 is an end view of the device illustrated in FIGURE 1, taken substantially along the line 2-2 of FIGURE 1 and looking in the direction of the arrows; and

FIGURE 3 is a partial view similar to FIGURE 1 and showing certain of the parts in a second position of operation.

Referring more particularly to the drawings, where the showings are for the purpose of illustrating a preferred embodiment of the invention only and not for the purpose of limiting same, FIGURES 1 and 2 best show the device as used with a relatively small dispensing roll of material, such as toilet paper. It is the normal practice to provide a suitable wall 10 with an opening 12 to receive a roll of paper, such as illustrated by dashed and dotted lines 14. A receptacle, indicated generally by the numeral 16', is provided with an outwardly extending peripheral flange 18 which is received against the face of the wall 10 around the opening 12, the receptacle 16 being provided with pin receiving openings 20. The rearward portion 22 of the recetpacle 20 is arcuately formed and of suitable size to receive the supply roll 14. It is to be understood that the particular construction of the receptacle 16 and the mounting of the receptacle 16 in the wall 10 have no part of the present invention.

Paper roll 14 includes an inner cardboard cylinder 24, around which the paper is wound to form the roll 14. Thus, a leading edge, indicated by the numeral 26, is the outward terminal end of the paper wound around the roll. As the paper is needed, the entire roll 14 and cylinder 24 are rotated until a sufficient amount of paper is freed from the roll. It is to be understood that the formation of the paper roll has no part in the present invention, it being only necessary that the material be wound so as to have a hollow central core.

Received within the cardboard roll 24 is an open ended cylinder, or housing, indicated generally by the numeral 28, which may be of any suitable material and may have an outer friction surface 30 to engage the inner surface of the cardboard cylinder 24. By proper sizing of the housing 28, and by the suitability of the friction surface 30, the housing 28 can be caused to rotate and carry with it the supply roll 14. Within the housing 28 and adjacent one end thereof, is a transverse wall 32, the purpose for which will become hereinafter more apparent. Telescopically received in the adjacent end of the housing 28 is an end member, indicated generally by the numeral 34, having a cylindrical portion 36 slidably received within the housing 28 and closed by an end wall 38. Extending outwardly from end wall 38 is a pivot shaft 40 which is receivable in one of the openings 20 in the receptacle 16. A shoulder 41 on the shaft 40 limits the location of the shaft 40 in the receptacle 16. Disposed between the inner surface of the end wall 38 and the transverse wall 32 in the housing 28 is a spring 42 biasing the end member 34 in an outward direction.

Mounted in the opposite end of the housing 28 is a motor, indicated generally by the numeral 44, sufliciently sized to be closely received within the housing 28 for rotation therewith. A suitable friction surface, or resilient surface, in the form of a sleeve 46 may be disposed between the motor 44 and the inner surface of the housing 28 to absorb any vibrations or the like that might occur. Extending outwardly from motor 44 is a motor shaft 48 which extends into the pivot pin receiving opening 20 at the left-hand side of the receptacle, as viewed in FIG- URE 1. A groove 50 is formed in the motor shaft 48 adjacent the wall of the receptacle 16 and a friction washer 52 is received and retained in the groove 50 to maintain the shaft 48 in a non-rotating position. It will be apparent that the biasing force of the spring 42 will cause the washer 52 to bear against the side wall of receptacle 16.

Also disposed within the housing 28 and between the transverse wall 32 and the motor 44 is a power supply means, conveniently shown in the form of a small battery indicated generally by the numeral 54. Battery 54 includes a contact post 56 which engages a contact strip 58 mounted on the motor 44. The transverse wall 32, engaging the opposite end of the battery 54, terminates in a contact strip 60 which engages the motor 44. The transverse Wall 32 thus serves as both a holding means for the battery 54 and a portion of the electric circuit, which will become hereinafter more apparent.

At the outward end of the motor 44 are a pair of spaced and concentric contact rings 62 and 64, each of which is electrically connected to the contact strips 58 and 60 respectively, interiorly of the motor 44 and in any suitable fashion.

Mounted on motor shaft 48 is an operating lever, indicated generally by the numeral 66, and having an enlarged opening 68 to permit the lever to be rocked about the shaft 48 in a manner to be hereinafter more particularly described. Formed in the motor shaft 48 and on opposite sides of the lever hub or opening 68 are grooves 70 and 72, the groves received retaining rings 74 and 76 to position the lever 66. A spring 78, bearing between the lever 66 and one of the rteaining rings, as 76, normally maintains the lever 66 in the position shown in FIGURE 1. Lever 66 includes an operating flange 80 at one end thereof and a contact flange 82 at the opposite end thereof. Contact flange 82 is so formed as to engage the contact rings 62 and 64 on the motor 44, upon actuation of the lever, to complete the electrical circuit to the motor 44 and cause operation thereof.

It will now be apparent that with the housing assembly disposed within a supply roll, the entire assembly may be mounted in a receptacle by compressing the end member 34 against the spring 42 to provide clearance for the shafts 40 and 48 and mounting of the assembly in the receptacle 16. When properly positioned, release of the end member 34 causes the spring 42 to bias the device in position and causes the friction washer 52 to bear against the wall of the receptacle 16. When it is desired to dispense material from the roll 14, the operating flange of the lever 66 is moved toward the left, to the position illustrated in FIGURE 3, thus causing the contact flange 82 to engage the contact rings 62 and 64. This completes the electrical circuit from the battery 54 to the motor 44 and causes rotation of the motor 44, the housing 28 and the supply roll 14 about the motor shaft 48. When the desired amount of material is dispensed. release of the lever 66 breaks the circuit at the contact rings 62 and 64, thus removing the power supply from the motor 44 and ceasing further rotation in a dispensing direction. When the material is completely dispensed from the supply roll, the assembly may be removed from the recptacle 16 by depressing the end member 34 into the housing 28, thus permitting clearance for removal of the assembly from the receptacle 16. The cardboard cylinder 24 may then be removed from the housing 28 and a new supply roll disposed thereon.

Thus, a motor driven dispensing device is provided which is extremely simple in its operation, economical in its manufacture and design and may be easily mounted in present receptacles for operation in the desired manner. It will be readily apparent that the device is adaptable to other sizes and shapes of dispensing rolls and provides positive rotation of the roll when it is desired to dispense material therefrom. The relatively few number of parts avoid any replacement or wear problems to a great extent, and avoid the necessity of requiring a large assembly which must be separately mounted in a desired location to operate as intended.
