Specification of Letters .Patent.

Patented June 2, 191 1.

Original application filed November 16, 1912, Serial No. 731,660. Divided and this application filed. April 1 b all whom it may concern Be it known that I, SETH \VHEELER, a c1t1- zen of the United States of America, and a resident of Castleton, county of Bensselaer, and State of New York, have invented certain new and useful Improvements in Holdersfor Paper-Rolls, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

My invention relates to improvements in holders or fixtures for paper rolls.

One object of my invention is to provlde a simple and durable fixture of this character that shall be adapted to support a roll of paper having a smooth cylindrical opening with or without the usual tubular core and shall be arranged to prevent the removal of the roll except by unwinding the paper.

Other objects will be set forth hereinafter. I will describe my invention in the following specification, and point out the novel features thereof in appended clanns.

Referring to the drawings: Figure 1 1s a partially sectional plan View of a fixture arranged and constructed in accordance with my invention, a roll of paper belng shown in broken lines, except for a small portion which is shown in section. Fig. 2 is an end elevation of the fixture and roll shown in Fig. 1. Fig. 3 is a plan view of one of the holding members which forms a part of the fixture of Figs. 1 and 2. The washer which forms a part of the holder is shown in Flg. it. A modified holding structure is shown in Figs. 5 and 6 which correspond respectively to Figs. 3 and 1. Fig. 7 shows the holder of Figs. 5 and6 as applied to a roll of paper. Another modification of my invention is shown in Fig. 8 which corresponds to Fig. 1. One of the holding members of this fixture is shown in Fig. 9.

Like characters of reference designate corresponding parts in all the figures.

Referring particularly to Figs. 1 to 4 of the drawings, the holding fixture comprises a base 10 which may be affixed to a wall or other suitable support. From it projects near one of its ends, an arm 11 preferably of spring sheet metal which is rigidly affixed to the base at 12. Near the other end of the base is a similarly shaped arm 13 but this is slidably connected with the base so that it may be moved away from and to- Serial No. 764,034.

ward the arm 11. Any suitable arrangement may be employed, such for example as that shown in the drawings. The lower part of the arm 13 passes through a slot 14. in the base and is bent over at right angles to form a tongue 15, which fits between the sides of the base and is guided laterally thereby. Under the tongue is a plate 16 which is riveted to the base at 17 and is held away from the under surface thereof a distance corresponding with the thickness of the tongue. The arm 13 is thus perma nently connected with the base 10, but may be moved along the base and in relation to the other arm 11 a distance limited by the length of the slot 1 1. A holding member 20 is supported by the arm 11 and comprises a pm or rivet 21, which extends loosely through a hole in the arm 11. Secured to the inner end of the pin is a flat disk 22 and a spherically curved disk 23 of thin sheet metal having a saw-toothed edge. A similar holding member 25 is supported by the arm 13. It however comprises a screw 26 which extends loosely through a hole in the arm and takes the place of the rivet 21 of the holding member 20. A wing nut 27 is mounted on the screw beyond the arm and is adapted to draw the screw outwardly, thereby setting the teeth of the disk 23 into the upper roll as hereinafter explained. The threaded shank of the screw is flattened on one side and the hole in the arm through which it passes is formed to fit the shank loosely but to prevent it from turning (see dotted lines in Fig. 2). The end of the shank is preferably upset to prevent the re moval of the thumb nut.

The fixture of my present invention is particularly adapted for use with rolls of paper, which either have no central core or are provided with a core having a smooth inserted in the fixture by first moving the roll 13 outwardly as far as it can go and then forcing the engaging members 20 and 25 into opposite ends of the roll or its core. This can be done easily because the disks 23 are convex inwardly and are constructed of thin sheet steel or equivalent material. The arm 13 may then be moved inwardly toward the arm 11 until the distance between the two arms is approximately equal to the longitudinal dimension of the roll. By tightcylindrical bore. A roll of this kind may be ening the thumb nut 27, both of the disks 23 are more or less flattened and the teeth :on their peripheries set into the inner layers of the paper or into the core. At the same 5 time the arm 13 is drawn against the adjacent end of the paper roll making a triotional hold which may be nicely adjusted to produce a desired tension upon the paper when it is withdrawn from the roll as such withdrawal has a tendency to rotate the roll relative to the fixture.

The fixture of my present invention may be utilized for holding rolls of relatively stiff paper which are practically inflexible,

15 since the disks 23 will yield and there is no occasion for the roll or the core to yield. The roll of paper can obviously not be removed when once it is placed upon the fix ture except by unwinding the paper.

The modified structure shown in Figs. 5, 6, and 7 differs from the structure shown in the previous figures in that each of the disks 23 is provided with radial slots or saw cuts 23 which increase the flexibility of the disk. 25 The arrangement of parts and the operation of the fixture is the same as that already described.

Referring particularly to Figs. 8 and 9, the fixture here shown comprises a base 30 having a pair of outwardly extending rigid arms 31 and 32, and holding members 33 and 34. The member 33 is preferably cylindrical and extends laterally inwardly from the arm 32, to which it is secured near its outer end. 35 The member 3% comprises a body 35 which has the general form of a triangular prism with rounded edges, and a plurality of. springs 36 which are riveted or otherwise secured to the body. The body 35 is mount- 40 ed on and secured to a. screw 38 which extends through a suitable hole in the arm 31 and is engaged by a thumb nut 39. The springs 36 are secured to the body near its inner end and flare outwardly to a diameter which corresponds substantially to the inside diameter of the core of the paper roll to be supported. Unlike the rolls shown in Figs. 1 to 7 inclusive the roll A0 of Fig. 8 is provided with a core A1 having an end restriction 42, one end of the core being formed into a funnel-shape and inset to provide an annular shoulder 43. The distance between the arms 31 and 32 is somewhat greater than the longitudinal dimension of the roll and consequently the roll may be placed between them with the cylindrical projection extending into the smooth end of the core 41. The body 35 of the holder may then be forced into the restricted end or" the core and the wing nut finally tightened to draw the roll against the inner surface of the arm 31. The springs 36 are compressed as the body is forced inwardly, but they expand as soon as the body passes the restricted portion of the core. They thus engage the shoulder 43 and prevent the removal of the roll. The friction between the end of the paper roll and the arm 31 may be adjusted as desired to retard the unwinding of the roll.

Structural variations may be effected without departing from the spirit of my invention and I only intend to be limited by the appended claims.

What I claim is:

1. A paper fixture comprising a base having outwardly extending arms, means adapted to be inserted in the central cylindrical opening of a roll of paper and to be expanded therein to prevent the removal of said roll except by unwinding and means adjustably secured to the arm and adapted to exert an outward pull on the expansible means.

2. A paper fixture comprising a supporting bracket having an outwardly extending arm, a spherically curved resilient disk adapted to be inserted in a cylindrical opening in a roll of paper, and means adjustably secured to the arm for expanding the spherically curved disk in order to prevent its removal from the roll of paper.

3. A paper fixture comprising a supporting bracket having an outwardly extending arm, a spherically curved resilient disk having a saw-toothed periphery, a bolt on which the spherically curved disk is supported extending through said arm, and an adjusting nut for expanding the disk to force the teeth into engagement with the roll and to prevent the removal of the roll except by unwinding.

In testimony whereof, I have hereunto set my hand this 25th day of April, 1913, in the presence of two subscribing witnesses.
