Abstract

A paper roll support made up of two roll members spaced from each other a distance less than the diameter of a roll of paper to be supported. Each roll is rotatable about an axis parallel to the other. Each roll has a pulley attached to one end and a belt is placed around the pulleys. The roll of paper can be supported on top of the two rolls with its central axis parallel to the central axis of the rolls with the free end of the paper on the roll extending down between the two rolls so that the roll of paper is carried on the rolls on roller bearings. The roll of paper rotates the two rollers as the paper is unrolled from the roll. The paper can be rolled up by pulling an endless belt that passes over pulleys connected to the rollers.

Primary Examiner-Edward .1. McCarthy [5 7] ABSTRACT A paper roll support made up of two roll members spaced from each other a distance less than the diameter of a roll of paper to be supported. Each roll is rotatable about an axis parallel to the other. Each roll has a pulley attached to one end and a belt is placed around the pulleys. The roll of paper can be supported on top of the two rolls with its central axis parallel to the central axis of the rolls with the free end of the paper on the,,roll extending down between the two rolls so that the roll of paper is carried on the rolls on roller bearings. The roll of paper rotates the two rollers as the paper is unrolled from the roll. The paper can be rolled up by pulling an endless belt that passes over pulleys connected to the rollers.

[FIGT ROLL SHEET SUPPORT REFERENCE TO PENDING APPLICATION This application is a continuation-in-part of and now abandoned patent application, Ser. No. 355,805, filed Apr. 30, 1973.

GENERAL STATEMENT OF INVENTION In decorating rooms for Displays and Backgrounds for Photography it is also desirable to be able to pull down a large sheet of paper from the ceiling 107 inches wide or larger. It is then often desirable to be able to roll up the sheet of paper after it has been used. Applicant has discovered that it is possible to handle large rolls of paper; for example, a roll weighing several hundred pounds, by supporting the roll on two rollers spaced from each other a distance less than the paper roll diameter and on parallel axes and to reroll this roll of paper simply by pulling on a belt, cord or chain around a pulley attached to each end of the roll.

OBJECTS OF THE INVENTION It is an object of the invention to provide an improved paper support apparatus.

Another object of the invention is to provide a paper support apparatus that is simple in construction, economical to manufacture, and simple and efficient to use. 7

Another object of the invention is to provide an improved paper support roll device for supporting and dispensing decorative paper and the like.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claim, it being understood that changes may be made in the fonn, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

GENERAL DESCRIPTION OF THE DRAWINGS FIG. 1 is an end view of the paper roll support according to the invention.

FIG. 2 is a front view of the support shown in FIG. 1.

FIG. 3 is an end view of another embodiment of the invention.

FIG. 4 is a front view of the embodiment shown in FIG. 3.

FIG. 5 is an isometric view showing the paper roll supported according to the invention.

FIG. 6 is a side view of the bracket supporting the rolls.

FIG. 7 is a front view of the bracket supporting the rolls.

DETAILED DESCRIPTION OF THE DRAWINGS Now with more particular reference to the drawings, the paper roll 21 is shown supported on the two spaced rollers 10 and 11. The rollers 10 and 11 have plugs in each end with an axle extending on each plug. These axles are received in bearing openings in

brackets

16 and 17. A pulley 18 is fixed to the shaft 12 and a pulley 19 is fixed to the axle 13. The pulleys may be of the V- belt type and an endless belt 20 passes around

pulleys

18 and 19 and has a substantial slack portion extending below said pulleys. When the operator pulls on the end 22 of the roll 21, the roll 21 will rotate the rollers 10 and 11 so that the rollers free wheel and, therefore, freely unroll the paper. If the operator desires to reroll the paper, he merely pulls on one end of the belt 20 and this rotates the rollers through

pulleys

18 and 19 and rerolls the paper.

In the embodiment of the invention shown in FIGS. 3 and 4, the rolls and 111 are shown supported on

axles

112, 113, 114 and 115 respectively. The ends of these shafts or axles are received in

brackets

116 and 117 and the rollers 110 and 111 are freely rotatable thereon. The rollers 110 and 111 can be rotated in either direction by means of the endless belt 120, which passes around the

pulleys

118 and 119 and around the idler pulley 121. Idler pulley 121 maintains a greater length of belt 120 in contact with rollers 110 and 111. Thus, a greater length of the belt 120 engages the

pulleys

118 and 119 than in the embodiments shown in FIGS. 1 and 2. This is important in large roll operation.

Referring to FIGS. v5 and 6, they show two spaced brackets 216 supporting two spaced

rolls

210 and 21 1. The

rolls

210 and 211 have axle members at each end which are shown in FIG. 5 supported in

slots

214 and 215 in flanges 216. I

Each of the flanges 216 is made of a platelike member bent at right angles forming the plate portion 222 and the flange 223. The rollers each have a pulley, such as pulley 18 andpulley 19 in FIG. 1 and FIG. 2, which are engaged by a continuous cord 228.

The brackets can be used to support two rollers vertically, as shown in FIGS. 6 and 7, by supporting the flange 223 on a ceiling and allowing the platelike portion 222 to extend downward. The roll of paper 224 would be supported on the

rollers

210 and 211 which have axles entending axially outward and engage the

slots

230 and 231.

Slots

230 and 231 are disposed at an angle of approximately 30 to the horizontal and they both extend downward toward the end 233 from the

sides

234 and 235 and terminate at equally spaced distance from the end 233.

When the plates 216 are attached to a wall as in FIG. 1, they may be attached thereto by

suitable screws

236 and 237. The flanges can likewise be supported on the ceiling by

screws

238 and 239.

When the brackets 216 are supported to a wall as shown in FIG. 5, the axles of the

rollers

210 and 211 are received in

slots

214 and 215. Slot 214 extends from side 235 at approximately midpoint between the flange and the end 233 to a point approximately equal to the center line of the plate 216. The slot 215 extends from the end 233 toward the center and toward the flange 223 and terminates approximately the center of the plates 216. Thus the brackets can be used to support the rollers from the ceiling or from a wall. By operating the cord 228, the roll of paper 221 can be rolled or unrolled.

The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
