YVILSON I-I. STRIOKLER, OF DODGE CITY, KANSAS.

LUBRICANT.

SPECIFICATION forming part of Letters Patent No. 476,574, dated June 7, 1892.

Application tiled April 6, 1891. Serial No. 387,723. (No specimens.)

T 0 all whom it may concern:

Be it. known that 1, WILSON H. STRIOKLER, a citizen of the United States, residing" at Dodge City, in the county of Ford and State of Kansas, have invented a new and useful Improvement in Lubricants and Steam-Packing for Steam-Engines, Journals, Bearings, Steam-Chests, Boilers, Steam and Hot-Air Pipes, and in general such parts of machinery as are exposed to friction orthe effects of heat; and I do hereby declare the following to be a full, clear, and exact description of the invent.ion,such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention consists in the application of the minerals asbestus, soapstone,and mica in combination tothe purpose of a lubricant and packing for machinery, and the mode in which I prefer to practice my invention is as follows:

The asbestns, soapstone, and mica are pulverized in a mill or by any other suitable means, and in this pulverized condition, preferabl y in about equal quantities, (more or less,) are mixed with oil and applied to the part to be lubricated. The pulverized asbestus, while overcoming the effects of heat and friction, also holds the pulverized soapstone and mica in suspension in the oil,thereby materially bettering its form and quality as a lubricant, and, being fibrous and expansive, makes a tight and most eifective packing. The laminated surfaces of the mica take up and hold in contact the oil, as well as the pulverized asbestus and soapstone. No matter how finely pulverized, the mica possesses a large surface of contact for the adhesion of these substances. Soapstone is not a necessary ingredient of my composition; butI prefer ordinarily to use it, as it imparts a desirable quality to the lubricant. W'hen used as a steampacking for engines, boilers, steam and hotair pipes, &c., it is mixed with cotton or any suitable fibrous material. In this manner it is used as a packing or sheathing for all parts of machinery conveying steam or heat.

I am aware that mica, soapstone, oil, and asbestos have heretofore been used separately and in combinations as lubricants, and I therefore lay no claim to the use of these substances or any of them separately, but only to the particular combinations hereinafter claimed, which I am not aware have heretofore been used or patented and which I have discovered possess peculiar advantages.

\Vhat I claim as my invention, and desire to secure by Letters Patent of the United States, is

A composition of pulverized asbestos, soapstone, mica, and oil, substantially as described. In testimony whereof I affix my signature in presence of two witnesses.
