SETI-I WHEELER, OF CASTLETON, NEW YORK.

OVAL ROLL AND CORE THEREFOR.

To all whom 'it may concern:

Be it known that I, SE'rH lWHEELER, a citizen of the United States, and a resident of Castleton, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Oval Rolls and Cores Therefor, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in oval rolls and cores therefor of the character adapted to be employed in a certain class of oscillating or rotating fixture employed in toilet rooms, and the objects of my invention are first, to compel the mounting of the roll in the proper relative position in the fixture; second, to facilitate the mounting of the roll in position; and third, to improve and simplify the construction of the core and reduce the cost of manufacture thereof.

To these ends my invention consists first, in a core provided with a substantially Hat opening from end to end thereof disposed eccentrically width-wise with respect thereto, one of the side edges of the opening being arranged in part or in whole at a different angle to the axis of the core than the other; and second, in a core constructed of two flat sheets in contact throughout except where they are offset to form the opening, the two sheets being provided with interlocking portions adjacent the opening, to secure them together.

In order that my invention may be thoroughly understood, I .will now proceed to describe an embodiment thereof, having reference to the accompanying drawings illustrating the same, and will then point out the novel features in claims.

In the drawings: Figure 1 is a view in central transverse section through an oval roll provided with a core constructed in accordance with my invention. Fig. 2 is a face view of the core removed from the roll. Fig. 3 is a view in central transverse section through a core upon an enlarged scale. Fig. 4i is a face view of the blank from which the core is constructed, showing the same before it has been folded to form the core. Fig. 5 is a View of a modified form of the core.

Specification of Letters Patent.

Application led March 4, 1910.

Patented Oct. 11, 1910. serial No. 547,203.

The oval roll in its entirety comprises a core 10 and a strip of paper 11 wound thereon. The core is substantially fiat so that the roll assumes the form of a substantially fiat oval. The roll is intended to be supported eccentrically in a fixture provided for the purpose, and for the purpose of mounting it in the fixture the core is provided with an opening 12 extending longitudinally therethrough from end to end, the said opening being made of a size and shape to fit a rotating or oscillating supporting plate with which the fixture is provided. This opening 12 is located eccentrieally width-wise of the core so that the roll will always tend to hang in a predetermined relative position. In order to compel the mounting ofthe roll in the proper position with respect to the hanger, I first taper the opening width-wise, the tapered form being designed to correspond with a similar taper of the supporting plate; and second, I dispose the longitudinal edge either in whole or in part, at one side of the opening at a different angle with respect to the axis of the core to that of the other edge, the same also being designed to correspond to the form and shape of the hanger. The tapered form of the opening will insure the roll being inserted in the hanger at the proper end, while the relative angularity of the edges will compel the roll being placed in position upon the hanger the right way up. Heretofore it has been necessary to give the attendants explicit instructions as to how to mount the rolls in the fixtures. These instructions were sometimes followed and sometimes not, but in either case delay or confusion, or both, was the result. By my present invention the roll must be mounted properly in the hanger for it cannot be mounted in any but the desired position.

The usual and preferred form of the core opening is that shown in Fig. 2 in which one edge 13 of the opening is parallel with the axis of the-core, while the other edge 14 is oblique thereto. It will, of course, be understood that this may be departed from, the essential feature being the difference in angularity with respect to the axis of the roll between the edges 13 and 14. It will also be understood that it is not necessary that the difference of angularity extend clear from one end of the core to the other. In Fig. 5 I have shown a modification in which one edge 13 is parallel with the axis of the core throughout, while the other edge has an oblique portion 14 and a portion 15 parallel with the portion 13. This form is advantageous for some purposes,-for instance, this form of core could be employed either with a xture having the usual flat parallel sided supporting member, or with a supporting member specially designed with one edge oblique either in part or throughout.

The core is constructed of two sheets 16-17 of cardboard or other desired material, the two sheets being preferably formed from a single strip bent in the middle, as at 18, (see Fig. t). Intermediate the side edges of the strip the sheets have coinplementary offset portions which, when brought together, form the longitudinal opening 12. One of the edges, 16, is conveniently provided with tongues 19 cut from the blank, and the other sheet 17 with complementary slits or openings 20. lVhen the strip is bent at 18 to bring the two sheets 16-17 together the tongues 19 may be inserted through the slots 20, as will be well understood by reference to the enlarged sectional view Fig. 3. This causes an interlocking between the two sheets and obviates the use of an adhesive material between them to secure them together. rIhis not only simplies and reduces the cost of manufacture, but I ind that it facilitates the mounting of the roll in position. Where a core is made of two sheets glued together except at the offset portions by which the core opening is formed, it is often exceedingly diflicult to get the roll started into place, this being for the reason that the core is apt to get slightly crushed and the offset portions forced together, thus practically closing the opening. In my present invention it is quite a simple matter to spread the two portions of the core slightly apart to start the roll in place so that even should the two elements be crushed quite flat they can still be quickly and readily inserted into place, the supporting member spreading the offset portions apart without any difficulty once the roll has been started into position.

What I claim is:

1. An oval roll comprising a substantially lat core having a longitudinal substantially flat opening therethrough disposed eccentrically width-wise thereof, the side edges of the opening being inclined the one toward the other, and a strip of paper, wound around the said core.

2. An oval roll comprising a substantially flat core "having a longitudinal substantially Hat opening therethrough disposed eccentrically width-wise of the core, portions of the side edges of the said opening being out of parallel, and a strip of paper, wound around the said core.

3. A core for oval rolls having a substantially flat longitudinal tapered opening therethrough, the axis of the taper being oblique to the axis of the core.

LI. A core for oval rolls having a substantially iiat longitudinal opening therethrough, one of the side edges of the opening being substantially parallel with the axis of the core and the other oblique with respect thereto.

5. A core for oval rolls having a substantially hat longitudinal tapered opening therethrough, the axis of the taper being oblique to the axis of the core, and the said opening being disposed eccentrically width-wise of the core.

6. A core for oval rolls having a substantially flat longitudinal opening therethrough, one of the side edges of the opening being substantially parallel with the axis of the core and the other oblique with respect thereto, the said opening being disposed eccentrically width-wise of the core.

7. A core for oval rolls comprising two pieces of sheet material arranged face to face and having complementary offset portions to constitute a longitudinal substantially fiat opening therethrough, the oHset shoulders at the opposite sides of the said longitudinal opening having transverse openings therethrough in one of the pieces, the other said pieces having tongues constituting extensions of the said shouldered portions which are received within the said transverse openings whereby to interlock the two pieces together.

8. A core for oval rolls composed of a single strip of cardboard folded in the center to form two flat sheets the faces of which are in contact throughout the maj or portion thereof and having complementary offset portions to constitute a longitudinal substantially flat opening therethrough substantially parallel with the folded portion of the strip, the offset shoulders at the opposite sides of the said longitudinal opening having transverse openings therethrough in one of the sheets, the other said sheet having tongues constituting extensions of the said shouldered portions which are received within the said transverse openings whereby to interlock the two sheets together.

9. A core for oval rolls composed of a single strip of cardboard folded in the center to form two flat sheets the faces of which are in contact throughout the major portion thereof and having complementary odset portions to constitute a longitudinal substantially flat opening therethrough, the offset shoulders at the opposite sides of the said longitudinal opening having transverse openings therethrough in one of the sheets, the

said strip and nearer the said folded edge other said sheet having tongues constituting than to the opposite edges thereof.
