Specification of Letters Patent.
Patented Jan. i2, i915.
Original application led December 14, 1908,'Sera1 No. 467,352. Divided and this application filed December 27, 1909.
To all whom it may concern.'
Be it known that we, LYNDE BRADLEY and HARRY L. BRADLEY, citizens of the United States of America,v and residents of Milwaukee, county of Milwaukee, and State of Visconsin, have invented a new and useful Improvement in the Process of lainlng Containers, of which the following 1s a specification.
Uury invention pertains to a process of ap-A plying an insulated lining to the interlor Walls of containers, vessels, etc., and relates especially to the process ofl placing such linings on the insulated resistor tubes or containers shown in our application filed December 14, 1908, Serial Number 467,352, of which this application is a division.
rlhe object of our invention is to provide an insulated lining possessing maximum heat resisting and wear resisting qual1fications.
In resistor containers or retainers no device has been known heretofore which combines maximum qualifications as to electrical insulation, heat-resisting and wear-resisting properties.
In the drawing which accompanies and forms a part of this specification-Figure l illustrates a form of resistor or container tube such as is adapted to use in our invention disclosed in theapplication referred to above.
Referring to Fig. 1, a metal tube 2 is lined with the insulating lining 24, attached to the wall of the tube by a layer of cement 25, as hereinafter described; the cement layer 25 being also an insulator, preferably.
`While we shall describe the process for applying the insulating lining to one form of container or retainer, it is understood that the process may be used with containers, vessels, etc., of any shape or form. The process of lining such a tube as that shown in the figure is as follows: A metal tube or container is coated on the interior with glass or porcelainl enamel, similar to that used on cooking utensils. This enamel is a composition resembling glass and variously known as porcelain enamel, vitreous enamel and glass enamel, and is in common use throughoutthe arts. The method of applying the coating of enamel to the interior of the tube is well understood in the arts and need not be described here. `This enamel lining has about the same coefficient of ex- Seral No. 535,223.
' pansion -as the metal wall of the tube, and
has the furtherA characteristic that when heated to a high temperature it becomes plastic and permits a kcertain slight relative movement between the surfaces of the re fractory lining, later applied, and the metal container, which it cements together.
Upon the completion of the enameling process the tubes are placed in a. machine designed to rotate or spin them with great rapidity upon their longitudinal axes. One end of the tube is then closed with a rubber stopper and a mixture of silica cement, potters clay and water is poured into each tube. The silica cement employed in this mixture is a material well known in the arts and is used for lining Bessemer converters. It is composed of ground ganister rock and lire clay. rl'he potters clay we use is preferably dark potters clay of the grade known as stoneware clay. We have found that a mixture of the following proportions is effective, although this is largely a matter of judgment, skill and experience, and will vary with the characteristics of the different batches of material used: Water, nine parts; potters clay, eight parts; silica cement, five parts by weight. The clays are dried separately at ordinary temperatures, ground to pass a Z0-mesh, and sifted. The wateris placed in the mixing vessel; then the potters clay, and thoroughly mixed; then the silica cement. The mixture is stirred thoroughly, then allowed to stand about fifteen minutes and again stirred thoroughly and used. A predetermined amount of the clay mixture having been poured into the tube, the remaining open end of the tube is closed lby a cap and the tube is rocked endwise to spread the cement fluid in pouring through the entire length of the tube. The tube is then locked in the horizontal position and rotated rapidly; the centrifugal action is such that the solid particles of the mixture are spread evenly aro-und and along the inner wall of the tube, most of the water remaining on the exposed surface. This rotating process consists of whirling the tubes for a period, then draining for a period and again whirling and draining until the coating of cement and clay has a characteristic degree of solidity and moisture, which is largely a matter of personal judgment and skill on the part of the operator. The tubes are then allowed to dry slowly ina vertical position, heat or forced air currents being used with caution, if desired. They are then raised to a temperature of about 80 degrees centigrade; this temperature causes the clay compound to assume a permanent condition and also causes the glass enamel to soften sufliciently to adhere to the clay coating, thus acting as a medium for binding the refractory lining of the metal tube.
The clay lining ifleft in this form would not have suicient mechanical strength to withstand the service for which it is lintended, therefore it is hardened by being saturated with'a solution of silicate of soda; this saturation is accomplished by filling the tubes with a solution of about 1400 specific gravity for twelve hours. The tubes are then cleared. with a small rubber vessel or squeegee, 'or rinsed with water and are. ready for a iinal baking.
For final baking a small receptacle containing one ounce of water is placed within each tube. A cap is placed on the top of the tube and they are put into an oven which previously has been raised to as high a temperature as will permit the operator to place the tubes in it with the hands unprotected. It is then raised to a temperature of about 400 degrees centigrade, and allowed to Vremain so for av period of about two hours. This baking with moisture is for the purpose of permitting the drying to proceed from that wall 'of the clay lining which is nearestv the glass enamel. When cool the tubes are inspected and any crystals of silicate of soda which may be found'on the surface of the clay wall are ground away; such tubes as pass inspection are then ready for service and may serve for containing any resistor, n
whether compressible or not.
Having fully described our invention, what we claim as new and desire to secure by United States Letters Patent is- 1. The process of making an insulationlined container which consists of lining a tubular metal container with enamel which becomes plastic when heated; then lining said container with a coating of refractory clay; then heating the container, thus lined, until the enamel softens and adheres to the clay lining; and then impregnating the clay lining with a solution of silicate of soda, and
then drying it.
2. The process of making aninsulationlined container which consists of lining a tubular metal container with an enamel which becomes plastic' with heat; then placing in the container, so lined, a plastic mixture of refractory clay and water; then spinning the tube on its aXis to distribute the clay mixtureA evenly `upon the wall of the tube; then drying said claynlining; and then heating the tube, so lined` to cause said cement lining to adhere to said clay lining.
3. The process-of making an insulationlined container which consists of lining a tubular metal container with an enamel which becomes plastic with heat; then placing in the container, so lined, a plastic mixture ofrefractory clay and water; then spinning the tube to distribute the claymixture evenly upon the wall of the tube; then drying said clay lining: then heating the tube, so lined, to cause said cement liningto adhere to said clay lining, and'subsequently impregnating the clay lining with a solution of silicate of soda to harden-it.
4. The process of making an insulationlined container .which vconsists of placing a quantity 'of refractory clay` in a plastic state, in a tubular container: then spinning said tube on its axis ata high rate of speed to distribute the plastic clay evenlyupon the inner walls of the tube, 4and then baking A the tube, so lined, to cause said clay lining to set in permanent form.
5. The process of making an insulationlined container which consists of placing` a. quantity of refractory clay, in a plastic state, in a tubular container: then spinning said tube on its axis at a high rate of speed to distribute the plastic clav evenlv upon the inner walls of the tube: then baking the tube, so lined, to cause said clay lining to set in permanent form; then impregnating said clay lining with a solution of silicate of soda, and finally drying it.
