part of this specification.
Like figures of reference refer to like parts.
This invention relates to prepared fabric belting and to the process of producing the same.
One of the objects of this invention is to provide a fabric belt having one face more flexible than the other, and having the more flexible side treated to increase its friction against pulleys, while having the opposite side treated to prevent stretching.
Any form of apparatus may be used that is suitable for carrying out my process of treating the fabric belting to produce one having the qualities which fulfill the above object. But as an example of such suitable apparatus, use the one which forms the subject of my pending application Serial Number lei-7,608, filed, February 9, 1917, under the title Apparatus and process for manufacturing belting. in using this apparatus, it is not always necessary to use the solution tank, .inasmuch as part of my process includes the application of the different solutionsby means of a brush. The fabric belt can be treated without soaking the fabric belt in any particular solution, although the belt might be prepared by first soaking the belting in a suitable solution of materials, adapted to give the belt its frictional qualities without making the same stiff, and afterwards by applying a gum solution to one side of the belt by means of a brush, while the belt is held stretched and until such gum solution hardens or dries to produce a flexible, but permanent surface, held thereby against shrinking to retain the belt in a stretched condition.
ln order to illustrate the difference between a flexible friction surface, and the permanently stretched surface of such a belt, reference is made to the figures of the drawings, wherein Figure l is a sectional elevation of such a specially treated belt. Figure 2 is a perspective view of the saine belt showing, by dotted lines, the bending of the belt in either direction, by the same force used in one case as the other.
Referring to the drawings the reference numeral l designates a fabric belting treated in accordance with this invention, one side 2 being treated to prevent stretching and the` other side 3 treated to and friction qualities.
in practice the side 3 of the belting is first treated with a rubber solution which penetrates part way into the fabric. The other side 2 of the belting is then treated with a solution of gum in a suitable solvent, such as for example alcohol or acetone. lVhile this Vsolution is being applied and until it hardens the belting is held under tension. As a result the belting is rendered waterproof and remains permanently stretched unaffected by the usual changes of temperature and strain during use.
- In Fig. 2 the treated belting is shown in full lines in normal position. The dotted line position A shows how the belting under a given force will become concave to the gum treated side 2. The dotted line position B shows how the belting under an equal force will become concave to the rubber treated side 3. It will be noted that the curve in position A is much flatter than the curve in Yposition B, .thus indicating superior .oending of the side 3 of the belting, which, incidentally is the one treated to increase its friction qualities, and intended to bear against the pulley.
Fabric increase its flexibility belting, preferably of cotton, as et forth above has been found to be most pactical and an excellent substitute for a. leather belt.
, Having described my invention, I claim,
l. The process of treating an integral fabric belting consistingl in treating one side with a rubber solution which penetrates part way only into the fabric, treating the other sido with a solution of gum and holding the belting` so treated under tension until the gum solution has hardened.
2. An integral fabric belting treated on one side with a rubber solution which increases its flexibility and friction qualities, and on the other side with a. gum solution which positively determines its dimensions under all kinds of weather conditions.
