No. 620.664. Patented Mar. 7, I899.

SPECIFICATION forming part of Letters Patent No. 620,664, dated March 7, 1899.

Application filed April 15, 1898. Serial No. 677,701. (No model.)

T0 at whom it may concern.-

Be it known that I, LoUIs NIssIM, mechani cian, a subject of the Sultan of Turkey, residing at 12 Leadenhall street, in the city of London, England, have invented certain new and useful Improvements in Elastic Bands; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to elastic bands such as are usually made of India-rubber or similar extensible material for the purpose of holding papers or in general for embracing a greater or less number of loose articles loosely connected together.

The object of my invention is to make such bands of greater strength than hitherto, the same thickness of rubber or the like being provided.

My improved elastic bands are made of a corrugated form,the corrugations being either concentric or radial and of any suitable shape.

In the accompanying drawings, Figure 1 is a plan of a circular elastic band constructed in accordance with my invention. Fig. 2 is a section on the line 2 2, Fig. 1. Fig. 3 is a plan, and Fig. 4 an edge View, of a band having radial corrugations. Fig. 5 is a perspective View of a modified form. Fig. 6 is a perspective view of another modification, a portion of the band being broken away to show the section; and Fig. 7 is a plan of a fourth modification.

Referring now to Figs. 1 and 2,the band illustrated is somewhat similar to the ordinary elastic bands cut from a sheet of india-rubber. Said band is, however, corrugated, as shown at a. The corrugations are arranged concentrically, and the angles of said corrugations are right angles. It will be furthermore observed that the lowest points of the troughs of the corrugations on the upper side of the band are in the same plane as the highest points of the troughs of the corrugations on the under side. I do not, however, confine myself to the exact shape of corrugation shown in Fig. 2, as the crests may be rounded, if desired, and corrugations of different angles may be employed.

In Figs. 3 and 4 the band is shown as being corrugated radially, and in Fig. 5 such a radially-corrugated band is shown in its deformed position encircling a roll of papers, for example, the roll being, however, not shown in the figure. Such forms of corru gation may advantageously be used when the band is not required to be stretched to any great extent.

Fig. 6 is a view of a band out from a tube of elastic material, the corrugations being disposed concentrically in planes perpendicular to the axis, a portion of the band being broken out to show the section. It will be observed that Fig. 6 exhibits the form taken by a band such as shown in Fig. 1 when the same is stretched.

Fig. 7 is a band of round or square section suitable for securing together the ribs of um brellas, for example,being particularly adapted for this purpose, since the tops of said ribs lie in the troughs of the inner corrugations, as will be readily understood.

Bands or rings made according to my invention will resist tension to a greater de* gree than ordinary bands made of fiat rubber. Furthermore, in the case of bands made with concentric corrugations, such as shown in Figs. 1 and 6, if one part of the band breaks the break will in general extend no farther than through one corrugation,where-' as with an ordinary india-rubber band when once it has begun to split it stretches at the break and the fracture extends from edge to edge, thereby rendering the same useless.

What I claim is 1. An elastic band consisting of a perma= nently-closed corrugated ring.

2. An elastic band, consisting of a permanently-closed continuously-corrugated rubber ring.

3. An elastic band, consisting of an annular sheet of radially-corrugated rubber.

In witness whereof I have hereunto set my hand in presence of two witnesses.
