CHARLES TENNANT LEE, OF BOSTON, AND CHARLES N. WAITE, OE MED- FORD, ASSIGNORS OF ONE-HALF TO THE GOULD & WATSON COMPANY,
OF BOSTON, MASSACHUSETTS.
ELECTRICAL NON-CONDUCTOR.
SPECIFICATION forming part of Letters Patent No. 386,925, dated July 81, 1883.
(No model.)
To all whom it may concern.-
Be it known that we, CHARLES TENNANT LEE,ofBoston,county ofSuffolk,and CHARLES N. \VAITE, of Medford, county of Middlesex, State of Massachusetts, have invented certain new and useful Improvements in Electrical Non Conductors, of which the following is a specification, reference being had to the drawing accompanying and forming apart hereof, in which is shown a sectional view of a piece of our non-conductor enlarged.
Non conductors 'for electrical purposes which can be produced in thin flexible sheets of large size are, so far as known to us, expensive and difficult to obtain.
The chief object of our invention is the production at slight cost of a non-conductor having a high degree of resistance, and which, when desired, may be produced in thin fiexible sheets of any required size; and it consists in a sheet composed of a layer or layers of fabric coated or filled with an insulating materialsueh as mica in a comminnted statewhich is attached thereto by an adhesive substance, such as glue, British gum. or the like.
In the drawing, a to represent the threads of the fabric, and b the mass of insulating material, the whole being very much enlarged for the purposes of illustration. We prefer to use a coarsely woven cotton cloth of fine thread, known as cheese cloth, when thin sheets of the non-conductor are desired; but, as will be obvious,when thinness of the sheet is not essential, a thicker and more closelywoven fabric may be used.
The mica may be applied in various ways to the fabric; but we prefer to apply it by saturating the fabric in glue size, then running the sized fabric th rough the comminuted mica, so as to thoroughly cover it with the same, and then passing the fabric through a pail-of rolls such as are commonly in use in a friction starch-mangle, and thus forcing the mica scalesinto and through the sized fabric. When the fabricis dried, a sheet of material is obtained having the non-conducting qualities of a continuous unbroken layer or sheet of mica.
As will be obvious, if a non-conductoris desired which shall be impervious to moisture, this result may be obtained by coating the sheets with shellac or other resinous varnish.
\Vhat we claim is A non -conductor consisting of a sheet or layer of textile fabric saturated or filled and covered with a compound composed of com lninuted mica and an adhesive material, as glue, substantially as set forth.
