Description
UNITED STATES PATENT OFFICE.
, DENNIS O. GATELY, OF NEWTOWN, CONNECTICUT Specification forming part of Letters Patent No. 26,489, dated December 20, 1859.
To all whom it may concern:
Be it known that I, DENNIS O. GATELY, of Newtown, in the county of Fairfield and State of Connecticut, have invented a new and use ful process of making machine belts or bands made in part or wholly of indie-rubber or gutta-percha; and I do hereby declare that the following description forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said invention, by which it may be distinguished from all others of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent.
The present invention consists in a new method of manufacturing a machine belting or banding for which I have made separate application for Letters Patent, the said belting or banding being composed whollyor in part of india-rubber or gutta-percha, and having a smooth and finished friction surface. The method. of producing this smooth friction-surface forms the subject of my improvement for which I wish to receive Letters Patent, and I will now proceed to describe the process in detail.
I take a strip or sheet of paper or cloth and give it a smooth, polished, or enameled surface in any manner, the best mode being by applying coats of anysuitable composition for producing the desired result. The composition I prefer is made of the following ingredients: French or pipe clay, soapstone-dust or black lead and any suitable water-proof glue or enameling-liquid, combined in any suitable proportions, and applied/to the sheet I or strip of paper or cloth witha brush or in any proper manner, and then dried or hardened by artificial heat or otherwise. The belt or band, being made up in any proper mode previous to vulcanization, is then rolled up with the strip or sheet having its surface covered with the enameling composition, as hereinbefore explained, soapstone-dust or black lead being sprinkled upon the strip or sheet or upon the belt to prevent their adhering to each other. The belt or band, while thus tightly wound up between the layers of the enameled strip or sheet, is then vulcanized by placing the whole in a steam heater or by subjecting it to a dry heat, or in any proper manner. By thus compressing the belt or band during the curing process between the layers of the enameled strip or sheet of paper or cloth the desired .efiect of imparting a smooth and finished friction-surface to'the belt or band is successfully attained.
It will be obvious that the winding or rollin g up of the belt or band can be eifected either by hand or by machinery. I
There are of course many substances other than those I have named which may be used for making the smoothing .or enameling composition for the cloth or paper-the ordinary patent leather or enameled leather or cloth composition, for instanceit being only necessary to use such a coating or compound upon the sheet or strip of paper orclothas will impart the desired smoothness to the surface of the belt or band.
The belt or band, instead of being rolled up with the strip or sheet of cloth or paper, may be placed in any position which will bring the friction-surface of the belt or band in contact with the smooth surface of the cloth or paper.
In preparing the composition above named I prefer to use glue which has been rendered water-proof; but this is not indispensable. I also prefer to use a composition which will be but slightly 'afiected by the steam or heat used in the vulcanizing process, as thus I am enabled to use the same cloth or paper more than once; but this is not indispensable.
The surface of the cloth or paper can be polished, if desired, and in many cases this produces the best efi'ect. If one side of the paper or clothis smooth and polished, or is covered with the smooth composition, one side of the belt only, when it is rolled up, is made smooth. If
both sides are made smooth and polished or covered, as above specified, then both sides of the belt are smooth and polished also.
I do not claim the use of cloth covered with an ordinary thin sizing-like cambric, for instance-as that does not prevent the impression of the threads of the cloth 'upon the surface of the belt; but
What 1 do claim as my invention, and de- 7 sire to have secured to me by Letters Patent,
The method herein described of manufacturing belts or bands of indie-rubber or guttepercha, the same consisting in placing them in contact with sheets or strips of paper or cloth having a smooth, enameled, or polished surface, substantially (LS set forth, and then beating them, as described.
DENNIS O. GATELY.
