1 Claim. (Ci. era-55.2

This invention relates to means for supporting rolls of paper or other wound material subject to controlled rotation whereby desired sections thereof may be drawn on and detached.

This invention has for an object to provide a arms hinged thereto, said arms carrying. journals to engage and mount the ends of the roll of paper or the like thereby to support the roll subject to rotation; said bracket arms being of such novel structure as to tensionally press against the roll ends so as to induce friction sufficient to prevent accumulation of momentum when the roll is rotated, thereby preventing undesired unreeling of the paper or the like therefrom in excess of the amount thereof drawn ofi for use; said arms being provided with stop means to abut the base when the arms are erected to service positions, whereby said stop means serve to both limit the swinging movement of the arms to an extent determinative of their erect service positions, as well as to provide purchase points whereby a desired tension of the arms may be attained.

The invention has for a further object to pro vide a fixture for the purposes stated which is collapsible to a compact comparatively fiat condition for storage and packing in quantity for shipment.

Other objects of this invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.

An illustrative embodiment of this invention is shown in the accompanying drawing, in which:

Fig. 1 is a top plan view of the paper roll mounting fixture in collapsed condition; Fig. 2 is a side elevation of the same, with the roll supporting arms erected preparatory to mounting a paper roll thereon; Fig. 3 is a transverse vertical section, taken on line 3-3 in Fig. 2; Fig. 4 is in part a side elevation and in part a longitudinal vertical section of the mounting fixture having a paper roll operatively supported thereby; and Fig. 5 is an end elevation of Fig. 4.

Similar characters of reference are employed in the above-described views, to indicate corresponding parts.

Referring tothe drawing, the novel paper roll supporting fixture comprises a base I0 stamped out of sheet metal, the same having a downwardly or rearwardly directed peripheral flange H skirting the same. Adjacent to each end of the base It! is a depressed seating portion I2 of less width than the base, and bordering opposite sides of saiddepressed portions, are raised hollow bearingmembers 13 which are stamped out of the base material. At least one of each pair of bearing members ;!3 is outwardly open to provide entrance ways M for the insertion of transverse hinge pins I 5.

Hingedly connected with the base in. adjacent to the ends thereof, are erectible bracket arms.

These bracket arms each comprise an integral structure formed from a sheet metal plate to provide a body l6 terminating at its upper end in a presser member I! preferably of circular periphery. Pressed out of each presser member is an inwardly directed journal boss l8 arranged to project from the inner face thereof. Said body I 6 terminates at its lower end in an inwardly and downwardly off-setting foot-piece I9 of reduced width, the same having at its extremity a transverse tubular hingingeye 20. Said body I6 is further provided for downward extension in the plane thereof adjacent to its foot-piece I9 and at opposite sides of the latter, with stop projections 2!, the same having their free ends opposed to the base H), at points outwardly of the hinged connection of the bracket arm therewith, when said arm is upswung to erect operative position. The bracket arms are assembled with the base H) by disposing their hinging eyes 2i] respectively in the depressed seating portions i2 between and in alignment with the opposed members of a pair of said bearing members I3; being then hingedly connected with the base by inserting a hinge pin l5 through the bearing members l3 and hingingeye 20 thus aligned.

Formed in the base H] are depressed slotted seats 22 through which fastening screws or the like may be passed to secure the fixture in afiixed relation to a wall or other desired supporting surface.

As shown in Fig. 1, the bracket arms may be down folded upon the base l0, thus collapsing the fixture and reducing its bulk to facilitate storing, packing for distribution, etc.

In the use of the device, the base I0 is immovably fastened to a wall or other selected supporting surface, and th bracket arms are upswung to operative erected relation to the base I 0, as shown in Fig. 2. To mount a roll ofpaper 23, which is usually wound upon a tubular core 24, the roll is inserted between the erected bracket arms. Initially the bracket arms, when erected, incline somewhat toward each other, as shown in Fig. 2, so that the distance between the pressed members I1 is somewhat less than the length of the roll ofpaper 23. The bodies l6 of the bracket arms, being made of springy sheet metal, will flex outwardly after the stop projections 2| abut the base l0. As a consequence of this the bracket arms will yield outwardly so as to permit insertion of theroll 23 therebetween with the journal bosses l8 respectively entered in the ends of the tubular core 24 of the roll, whereby the latter is subject to rotation on and about the journal bosses to permit sections of the roll content to be drawn off and detached therefrom. The rearward flexing of the bracket arms, when stopped by the abutment of thestop projections 21 with the base l0, stores sufiicient tension therein to cause the presser members H, which surround the journal bosses l 8, to yieldingly thrust against the ends of the roll, so as to exert a braking friction thereon, this braking friction will not impede rotation of the roll when pulling away sections of paper desired to be detached therefrom, but will, however, ofier enough resistance to rotation to overcome accumulation of momentum when the roll is rotated, and will thus prevent the roll from spinning and. reeling off of more paper than is desired at any given time.

It will be obvious from the above description that not only does the instant invention provide a very efiicient supporting and dispensing means for rolls of paper and like material, but also provides a structure for such service which is mechanically simple and inexpensive to produce, since it comprises but three sheet metal stampings, viz. the two bracket arms and the base, and but two additional parts, viz. the pivoting hinge pins.

I am aware that som changes could be made in the described structure, and many apparently widely different embodiments of this invention could be made without departing from the scope of the invention as defined in the following claim. It is therefore intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

I claim:

In a fixture for the purposes described, a base and spaced bracket arms hingedly connected with said base, each bracket arm comprising a sheet metal structure provided by a tensionally flexible body having at its free end a presser member provided with a roll engaging journal boss projecting from its inner face, said body having at its opposite end portion an inwardly curved extension of reduced width, said extension terminating in a hinge eye by which it is pivotally connected with the base, and said body having at each side and in the plane thereof stop elements projecting beyond the juncture of said curved extension therewith toward said base, said stop elements being adapted to engage the base top to limit the pivotal movement of the body, whereby flexing movement of the latter and its extension beyond stopped position will store energy therein sufficient to frictionally engag the presser member thereof with a roll end rotatably mounted on its journal boss.
