Y '0 (all whom it may concern.

Be it known that I, RUDOLPH J. Vnnovnrn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Belting and the biles engines, sewing" machines, etc., al- I though, it willpresently appear that the usefulness of the invention is by no means limited to this particular service.

The leather belting herein particularly referred to is usuallymade in sizes of approximately three-eighths of an inch in width and one-fourth of an inch in thickness; and the belting of the present invention is well adapted for use in these sizes in particular.

One of the objects of the present invention is to provide a belting of this general class and size which shall possess a relatively high tensile strength and which will be extremely flexible.

Another object of the invention is to provide a belt of such form that it can be made from what is known as chrome leather as distinguished from other leathers, such as oak leather, etc. In this connection, I will state that chrome leather possesses a very high tensile strength, but is very expensive and diflicult to obtain in the thickness which would ordinarily be needed for belting for these purposes. By the use of the features of the present invention, however, it is possible to make use of chrome leather in relatively thin strips which can be obtained at a relative low cost in the market.

As a matter of convenience, I have illustrated in the drawing a strip of leather belting embodying the features of the present invention, wherein- Fig. 1 shows a perspective view of a strip of belting embodying the features of the present invention; and

Fig, 2 is a cross section taken on the line 2-2 of Fig. 1, and on enlarged scale.

In practicing the present invention, I prefor to take a strip of chrome leather which is relatively thin and of double the width which it is intended to orovide in the completed belting. I then fold this strip along its center line so as to double the thickness and halve the width of the belt; and then I prefer to stitch the belting along the center line of the folded strip. This stitching serves to retain the strip properly folded when the belting is new while at the same time allowing the two halves of the folded strip to move relatively so that the belting itself is very flexible and in fact much more flexible that would be a solid strip of belting of the same over all dimensions.

In connection with the use of chrome leather for this purpose, I wish to point out that sheets of chrome leather of full thiclmessare rather diflicult to secure and are very expensive. In fact, for these reasons, it would be practically impossible to produce belting commercially of th same hereinbefore mentioned dimensions if it were-necessary to out said belting from a sheet of chrome leather of full thickness. Nevertheless, so called split sheets of chrome leather may be had in commercial quantities and at relatively low cost, when the thickness is in the neighborhood of oneeighth of an inch which is appropriate for the manufacture of the belting embodying the present invention. Split sheets of chrome leather possess practically double the tensile strength of ordinary oak leather; the chrome leather is not affected by heat nearly as much as is the case with oak leather; and furthermore, the chrome leather is practically impervious to the action of water and oil. It will thus be seen that by using a belting made of mate-rial of practically one-half the thickness of the completed belting, and folded in the manner hereinbefore explained, not only possesses inherently certain very desirable quantities, but also makes it possible to use chrome leather with all of the advantages and benefits which attend the use of this.

particular material.

In making the belting of the present invention, I prefer to use the flesh side of the split hide, since: this part of the hide is the strongest, but I do not limit myself to the use of this portion of the hide, except as I may do so in the claims. Furthermore,

it is evident that in some cases it may be found desirable to fold the strip more than once, thereby producing more than two thicknesses of the leather in the belting. Also in some cases two or more independent strips of split leather may be set together face to face and then sewed together instead of folding a single strip which is ordinarily of a suflicient width to provide all of the thickness. I therefore contemplate the use of two or more thicln'iesses of split chrome leather either folded or severed from each other, and intend to cover these features of the invention broadly, except as I otherwise limit myself in the claims.

I claim:

1,. As a new article of manufacture, a strip of leather belting comprising a strip of split" chrome leather from the flesh side and of substantially one-half the thickness and substantially double the width of the desired thickness and width respectively of the completed belting, said strip being folded along its central line, and the line of stitchin extending along the central line of the foldec belting, whereby there is produced a strip of belting possessing the advantages from the use of split chrome leatl'ie'r from the flesh side, and whereby the strip of completed belting possesses great flexibility, strength and pulling power, substantially as described.

2. As a new article of manufacture, a strip of leather belting comprisinga strip of chrome leather from the flesh side of substantially one-half the thickness and substantially double the width of the desired dimensions of the completed belting, said strip being folded along its central line, and the line of stitchingextending along the folded strip a substantial distance from the edges thereof, whereby there is produced a strip of belting possessing the ad vantages and benefits from the'use of chrome leather from the flesh side, and whereby said strip of belting ossesses great flexibility,

strength, and pul ing power, substantially as described.

3. As a new article of manufacture, a

strip of leather belting comprising a plurality of thicknesses from the flesh side of split chrome leather laid together face to face and joined together by a line of stitching extending lengthwise of the belting, whereby there is produced a strip of belting possessing the advantages and benefits from the use of split chrome leather from the flesh side, and whereby said strip of belting possesses great flexibility, strength, and pulling power, substantially as described.

at. As a new article of manufacture, a strip of leather belting comprising a plurality of thicknesses of chrome leather set together face to face and joined together by a line of stitching extending lengthwise of the belting, whereby there is produced a strip of beltingpossessing the advantages and benefits from the use of chrome leather, and whereby said strip of belting possesses great flexibility and strength, substantially as described.
