PAPER DISPENSER Filed March 22, 1965 INUENTOZS ye ATMJMZZPM ATTOQNEYS United States Patent Filed Mar. 22, 1965, Ser. No. 441,434 6 Claims. (Cl. 242-55.53)

This invention relates to a paper dispenser.

The rear wall of a cabinet is designed to provide a mount and the remainder of the cabinet is pivoted to arms which project forwardly from the rear wall. One of these arms is formed to provide a fulcrumed support for a channel-shaped mandrel swingably mounted thereon. The other arm provides a seat to and from engagement with which the free end of the mandrel swings.

The mandrel has friction brake means projecting from its open bottom to resist the rotation around the mandrel and brake means of the core of an elongated roll of paper to be dispensed. In lieu of an elongated core, the mandrel and brake means may provide support for two shorter cores placed end to end and adapted, for example, to enable one roll of toilet paper to be in service while another one is held on the same mandrel in reserve.

In the drawings:

FIG. 1 is a view in perspective of a dispenser supported in a position for use.

FIG. 2 is a view in perspective showing the front of the cabinet dropped down and the mandrel swung up to a position for the reception or interchange of roll cores.

FIG. 3 is a view similar to FIG. 2 showing the mandrel having its free end swung into interlocking engagement with an arm which provides a seat therefor.

FIG. 4 is a view taken in vertical section through the cabinet and the mandrel.

FIG. 5 is a fragmentary detail view taken in section on line 5-5 of FIG. 4.

The cabinet back 6 is intended to be mounted in any appropriate manner from a wall. It has forwardly projecting arms at 8 and 10 which are preferably provided with embossed channels at 12 and 14 for reinforcement.

The arm 8 has ears at 16 and 18 which support a pintle 20 upon which a channel-shaped mandrel 22 is pivoted to swing between the position shown in FIG. 2 and that illustrated in FIGS. 3 and 4. The fixed arm 10 of the cabinet has an upward projection at 24 which is made to fit the free end portion 26 of the channelshaped mandrel 22 so that when the mandrel is in the operative position illustrated in FIG. 3 the free end 26 of the mandrel will embrace the projection 24 to be positively positioned thereby.

A portion of the cabinet which comprises end walls 28 and 30, front wall 32 and top wall 34 is pivoted for movement between the positions in which these parts are respectively illustrated in FIGS. 1 and 2. Conveniently, the rivets shown at 36 pivot the movable portions of the cabinet to the fixed portion thereof by pivotally connecting the end wall 28 with the arm 8 and the end wall 30 with the arm 10. A lock 38 may be used to iconnect the top wall 34 with the rear wall 6 of the cabinet when the parts are closed as shown in FIG. 1.

A feature of the invention consists in the provision of at least one offset stop member 40 embossed inwardly of the end wall. As illustrated, the stop member 40 is formed on the end wall 30 in a position such that when the movable portion of the cabinet is swung to its closed position as shown in FIGS. 1 and 4, the stop boss 40 overlies the free end portion 26 of the mandrel 22 thereby locking the mandrel securely to the supporting projection 24 provided therefor on the end of arm 10. The fact that the mandrel is closely confined between the boss 40 and the illustrated in FIGS. 4 and 5.

At an intermediate point the mandrel 22 is desirably provided with a rib 42 which is transverse with regard to the mandrel and serves to separate the core 44 of paper roll 46 from the core 48 of the reserve paper roll 50. This rib is shallow and when a single elongated roll is placed on the mandrel, its core readily spans the rib 42.

In order to provide a certain measure of resistance to prevent overrun of a roll from which the wound web is being withdrawn, it is preferred to equip the mandrel 22 with a brake which may be a spring or springs which act on the respective cores. Thus, as shown in FIGS. 2 and 4, I may provide a clock spring brake at 60 which has suflicient length in general parallelism with the mandrel to engage both the cores 44 and 48. Resilience is provided by forming the brake spring in the shape of a Very wide U, its leg 62 being riveted to the mandrel at 64 and its leg 66 having a finger 68 which projects longitudinally of the mandrel and is freely reciprocable through a guide strip 70 with which the mandrel is provided. The generally horizontal intermediate portion of the brake spring 60 is preferably rounded in transverse section as indicated by the shading in FIG. 2 and also curved at its ends as shown in FIG. 4. It preferably engages the core or cores with sufficient pressure to provide light braking action without impairing such rotation as is required during normal withdrawal of paper from the roll wound on the respective core.

We claim:

1. In a dispenser the combination with a wall mounting comprising spaced forwardly extending supporting arms having upward projections, of a channel-shaped mandrel extending from one arm to the other for support of a core on which a web is wound, the channel of the mandrel embracing the upward projections of both arms, said mandrel having pivotal connection with one of said projections and having a free end portion swingable upwardly and downwardly about said pivotal connection and releasably engageable with the projection of the other arm.

2. A combination according to claim 1 in which the mandrel is long enough to receive a plurality of such cores and has a transverse core-positioning rib for spacing two cores from each other.

3. In a dispenser the combination with spaced supporting arms having upward projections, of a channelshaped mandrel extending from one arm to the other for support of a core on which .a web is wound, said mandrel having pivotal connection with one of said projections and having a free end portion releasably engageable with the projection of the other arm, a cabinet comprising a back wall with which the respective arms are connected and a swingable cabinet portion comprising end walls pivoted to the respective arms, one of said end walls having a stop means adapted in one position of the last mentioned end wall to overlie the free end portion of the mandrel when the latter is engaged with the last mentioned projection.

4. In a dispenser the combination with spaced supporting arms having upward projections, of a channelshaped mandrel extending from one arm to the other for support of a core on which a web is wound, said mandrel having pivotal connection with one of said projections and having a free end portion releasably engageable with the projection of the other arm, the channel-shaped mandrel opening downwardly and has spaced side flanges, and an elongated spring mounted and guided between said flanges and having a connection at one end with the mandrel and a portion resiliently yieldable with regard to the mandrel and spaced below the mandrel projection 24 is very clearly 3 sufiiciently to engage the core of a paper roll encircling the mandrel.

5. A dispenser according to claim 3 in which the spring means comprises a spring strip connected at one end within the channel-shaped mandrel and having a leg portion extending to a level below the mandrel, and a brake portion extending along the mandrel, and another leg portion extending from the brake portion into the channel of the mandrel, and guide means within the channel-shaped mandrel and with which the last mentioned leg portion has means providing interlock.

6. A dispenser comprising a rear wall adapted to be mounted for the support of the dispenser, cabinet portions pivoted to the rear wall and including end, top and front wall components, the rear wall having forwardly projecting arms, pintle means engaged with the end Wall components and with said arms, upward projections on said arms, a mandrel for paper roll cores and comprising an inverted channel having pintle means connecting it with one of said projections and having a free end portion into which the other of said projections is normally fitted during operative use of the mandrel as a means of positioning said free end portion thereof, the

mandrel being adapted to be encircled by at least one paper roll core, brake means carried by the mandrel and including portions within the channel thereof and other portions projecting beneath the channel and adapted for engagement with the core of an encircling paper roll, the mandrel having a free end portion pivotally movable about said pintle means to a position for removal and replacement of such cores, and interlocking means comprising parts of the mandrel and of the movable portion of the cabinet for holding the free end of the mandrel engaged with the extension fitted therein when said movable cabinet portion is in its normally closed position.
