This invention relates to holders for rolls of sheet material, such as wax paper and paper toweling.

An object of the invention is to provide an inexpensive and efiicient holder for dispensing sheet material from a roll and of such character as to facilitate the withdrawal and severance of the material from the roll and to avoid waste of the material. 7

Another object of the invention is to provide a roll holder by which the roll will be automatically locked or braked when a piece of material is to be severed from the roll.

The invention further consists in the several features hereinafter described and claimed.

In that form of the invention shown in Figs. I to 6, l5 designates a sheet metal wall plate or back plate which is adapted to be secured to a supporting wall I6 by screws I! passing through key-hole slots 3 formed in the plate. The upper portion of the plate is bent forwardly and has a horizontally extending curled edge or bead l9.

A bail-like hanger formed of round wire has a horizontally extending shaft-like intermediate portion 2| pivotally confined in the bead l9 West Allis, Wis., a corof the wall plate, and has resilient depending arms 22 at opposite ends provided with curved or arched inturned projections 23 to loosely enter the opposite ends of a hollow roll 24 of sheet material, such as wax paper. In many instances, the roll 24 has a tubular core 25 on which the sheet material or Web is wound. The roll bears at its rear against the supporting wall It and is rotatably supported on the arched projections- 23, which engage the inner surface of the core at points spaced from the ends of the core, so that if the core ends should be damaged they will not interfere with the rotation of the roll. The hanger 2B is suspended in inclined position from the wall plate, the projections 23 being forward of the pivotal axis ofthe hanger.

A stirrup-shaped yoke or frame 26 of round wire has a horizontal intermediate cross bar portion 2? and arms 28- at opposite endsthereof, the arms having terminal loops or eyes 29 at their upper ends pivotally engaging about the shaft-like intermediate portion 2| of the hanger 20 adjacent the opposite ends of the bead E9 of the wall plate. The horizontal bar portion 2'5 of the frame 26 is spaced forwardly of the rollsupporting projections 23, and pivotally carries a sheet metal member 30 having a curled or folded intermediate portion 3| embracing the horizontal bar portion '27, the member 30 being thereby confined on the frame. The member 30 has a substantially fiat brake portion or shoe 32 bearing on the upper surface of the roll adjacent the front of the roll and has a cutting flange 33 extending substantially at right-angles to the brake portion 32, the cutting flange 33 having a serrated outer edge at. over which the outer or free endportion 35 of the paper web passes.

In order to protect the roll from dust, the pivoted frame 26 has mounted thereon a sheet metal panel 36 the opposite ends 37 of which are wrapped about the side arms of the frame, and the upper edge 38 of which is hooked to engage over the curled upper edge or bead Is I of the wall plate, Fig. 5. The lower edge of the panel 3% is spaced above the sheet metal cutting member 30 to admit the paper end 35 between them.

The roll 24 is applied to the holder by entering one end onto one of the hanger projections 23, and then springing the other projection so asto permit it to enter the other end of the roll. During this manipulation, the cutting frame 26,. 39, may be swung upwardly to the dotted line position seen in Fig. 1. The outer end 35' of the paper web is then passed through the space between the cutting member 30 and the lower edge of the panel 36, and the device is then ready for use.

When paper is to be dispensed from the roll the free end 35 of the paper web is drawn outwardly by hand in an approximately horizontal direction, as indicated by dotted lines in Fig. 1. During this withdrawal the roll will turn without excessive resistance. When the desired. length of paper is unwound from the roll, the paper end is swung downwardly to the approximately vertical position shown by full lines in Fig. l, or to the steeply sloping position shown by dotted lines in Fig. 1, and tension is applied to the paper end, whereupon the brake shoe 32 will press firmly against the roll 24 and prevent rotation of the roll. The paper may then be torn off along the serrated cutting edge 34, preferably starting at one side edge of the paper and progressing to the other edge. During the tensioning and cutting of the paper the roll also presses rearwardly against the supporting wall l6 which assists the braking action on the roll, although the roll would be adequately braked even if the engagement of the roll with the supporting wall were of frictionless character. The eccentric mounting of the roll on the hanger projections 23 aids the rearward urging of the roll against the supporting wall. When a succeeding portion of the paper is to be severed, the roll may be turned by hand through a part of a revolution so as to project the paper end forwardly of the cutting edge 34 and thus permit easy grasping by the fingers. As the roll becomes smaller, the rollsupporting hanger 20 and pivoted frame 26 swing rearwardly to steeper angles. The pivotal mounting of the member 30 on the cross bar 21 permits the brake shoe of this member to adjust itself to the surface of the roll as the roll becomes smaller.

The holder will accommodate rolls of relatively small diameter, such as wax paper rolls, as well as rolls of considerably larger diameter, such as paper toweling rolls, and will also accommodate rolls having core openings of widely different diameters. In addition, rolls which vary somewhat in length can be used on the holder.

When the holder is packed for shipment, storage or sale, it may be folded to the compact condition indicated in Fig. 4 and placed in a, suitable container or package 39.

The modified form of holder shown in Figs. '7 and 8 has a wall plate I similar to the wall plate l5 of Fig. 1, but extended downwardly and having its lower portion bent to form a forwardly projecting V-shaped bead or rib 4D with a narrow roll-engaging edge against which the rear portion of the roll 24 bears with a braking effect, the rib extending parallel to the roll and having a roll-indenting action when the roll is urged rearwardly. The roll-supporting hanger 20 is the same as that of Fig. 1, and is pivotally mounted in the same manner. The distance between the shaft portion of the hanger and the roll-engaging ends thereof is approximately the same as the distance between said shaft portion and the rib 40, and the rib extends behind the lower portion of the hanger. The holder has an open stirrup-shaped wire frame 26 provided with side arms 28 having looped or eyed ends 29 pivotally mounted on the shaft portion of the roll-supporting hanger. The frame 26 has a horizontal cross bar 21 which extends parallel to the roll and directly engages the roll. The upper edge of the cross bar 21 is pinched and serrated at 34' to form a paper-cutting edge, as best seen in Fig. 8. In this holder the rib 40 has a roll-braln'ng action which is in addition to that of the cross bar 21'. The operation of the holder of Figs. 7 and 8 is substantially the same as that of Fig. 1 except for the braking action of the wall plate rib 40.

The modified form of holder shown in Figs. 9 and 10 has a wall plate I5" extended downwardly to form a bearing surface for the roll. The roll-supporting hanger 20 is the same as that of Fig. 1 and is pivotally mounted in the same manner. The holder has a swingable open frame 26" consisting or a stirrup-shaped sheet metal strap, the bent arm-forming portions 28" of which have apertured ends 29" to pivot on the shaft portion of the rollsupporting hanger. The frame 26" has a horizontal cross bar portion 21" which directly engages the roll. The upper edge 35" of the cross bar, Fig. 10, is serrated to form a paper-cutting edge, and the lower edge 32 is serrated to form a braking surface engageable with the roll, although the latter edge may be left plain, if desired. The operation of the holder of Figs 9 and 10 is substantially the same as that of Fig. 1.

The holder of Figs. 11 and 12 is the same as that of Fig. 1 except that the panel 36 and the braking and cutting member 30 are omitted from the stirrup-shaped brake frame 26. This construction is suitable for use with a roll 24 of sheet material, such as paper toweling, which is provided at intervals with lines of weakening 42. The cross bar 21 bears directly on the roll and the paper end 35 passes over the bar and presses down thereon to exert a braking action on the roll when the paper end is tensioned downwardly, thus causing the paper to tear at the line of weakening 42. The operation of the holder of Figs. 11 and 12 is similar to that of Fig.1 except that the tearing line is determined by the line of weakening 42 rather than by the bar 21.

The structures disclosed in the present application and in my copending application for Roll holder, Serial No. 215,592, filed June 24,1938, have features in common, but the claimed subject-matter of the present application embraces features which are not disclosed in the said copending application.

What I claim as new and desire to secure by Letters Patent is:

A roll paper holder, comprising means for rotatably supporting a roll of paper, a pivotally supported member having a wire cross bar adapted to extend across the roll, and a sheet metal strip folded longitudinally about said cross bar and having a bearing portion extending more than around said cross bar and thereby pivotally secured thereon, said strip having a paper-severing edge and having a portion bearing on said roll to prevent rotation of said strip on said cross bar.

2. A roll paper holder, comprising means for rotatably supporting a roll of paper, and a swingably mounted frame having a cross portion with opposite edges one of which is serrated and adapted to rest on said roll to exert a braking action thereon and the other of which is adapted to receive thereover the free end of the paper of said roll for severing the paper.
