UNITED sTATEs PATENT oEEIcE.
EVEREST A. IEAYLIS, OF MADERA, MEXICO.
PROTECTIVE COVERING FOR CON CENTRATOR-TABLES AND METHOD OF APPLYING .THE
' SAME.
Application led Aug-ast 15, 1910. Serial No. 577,131.
Specicaton of Letters Patent.
Patented Sept To all rwhom t may concern.'
Be it -known that I, yEvEREs'r A. BAYLIs, a citizen ofthe United States, residing at Madera, in the State of Chihuahua, Republic of MeX'ico, have invented certain new and useful Improvements in vIrotective lCoverings for Concentrator-Tables and Methods of Applying the Same; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to concentrator tables such as are used in connection with the cyanid process of extracting the .metallic content from ores.
The invention especially relates to a protective covering for such tables and the method of applying the same to the tables.
It is well; known in the art that concentrator tables for use with the cyanid process must have a protective covering of some sort and heretofore it has been customary to cover' such tables with linoleum. This material has proven defective as a covering because of the fact that when first applied it is more or less wavy and the tables cannot bev used immediately. It is also defective in that the material from which the linoleum is made, being linseed oil, is acted upon by the cyanid so that it is softened and roughened and is also acted upon by any lime that may be contained in the material passing over the table with the result that deposits of lime scale (calcium carbonate) are made, thus forming lumps and making thesurface of the table uneven.
'The principal object o f the present 1nvention is the provision of a protective cover for cyanid tables which will not be acted upon by either cyanid or strong lime solutions.
is .a v.section throng tables composed of canvas palnted and ap plied in a novel manner.
lathe accompanying drawings a portion of.
Figure 1 a cyanid `rest the riflies 14.
At 15 is the third and inal coat of paint which is applied over the riiiles and the second coat of paint between the riiiies. The paint which is used is a peculiar paint commonly called throughout the United States 1). & B. paint and this paint has the peculiar properties of resisting the actions of acid, alkali, heat, cold, and is especially powerful in resisting the action of potassium cyanid.
The method of applying this cover is as follows A strip of canvas of suitable size, preferably number 10 duck, is cut out to the proper size to fit the table. One side of this canvas is then painted with the 1). & B. paint. This canvas is then applied to the table with the painted side down, stretched tightly and tacked. By having this single coat of painton the canvas the latter may be made to lie very snugly on the table and the. stretching process 1s much facilitated. After the canvas has thus been stretched a second coat of P. & B. paint is Tapplied:
The riflies are then nailed on the table and a 'third coat of 1). & B. is applied to cover the riiies and that portion of the canvas between said riiles. When the third coat of paint has dried the table is ready for use. The P. & B. paint herein referred to is that described in the United States Letters Patent #384,995 granted September 14, 1886, and comprising a compound of bisuld of carbon and maltha.
Having thus described the invention, what is claimed as new, is :M
1. The combination with a. concentrator table; of' a cover therefor comprising canvas painted on one side with 1). & B.
,paint and stretched over and secured to said table, the painted side being undermost, a second coat of said paint covering thev upper side of said canvas, riilles secured to said table on top of said cover, and a third coat of said paint covering said rifHcs and cover.
2. The process of preparing a concentrator table which consists in coating a canvas cover with a paint capa-ble of resisting the actions of potassium cyanid and alkaline solutions, applying the canvas to the table with the painted side down, stretching and securing the canvas to the table, applying a second coat of the same paint to the stretched, canvas, securing l'i'les on top of said cover, and nally applying a third/coat of the same paint.
In testimony whereof, I aX my signature, in presence of two Witnsses.
