JOHN B. NORRIS, OF RICHMOND, VIRGINIA.

LUVBRICANT.

SPECIFICATION forming part of Letters Patent No. 267,920, dated- November 21, 18 82.

Application filed August 17,1sss. (No specimens.)

To all whom, itmag concern:

Be it known that LJOHNB. NORRIS, a citizen of the United States, residing at the city of Richmond, in the county of Henrico and State of Virginia, have invented and made a new and useful composition of matter to be used for lubricating machinery of all kinds, and for the purpose of preventing undue heat and for extinguishing fire; and I do hereby declare that the following is a full, clear, and exact description of the same, which will enable others practically skilled in the branch of art and mechanism to which the same is applicable to make and use the composition.

My invention has for its object the perfect and edective lubrication of all forms of machinery; also, to prevent expansion, softening, and wear and tear by extreme heat, and to keep the metal parts in their normal indurate condition of temper; also, to prevent corrosion and oxidation of metal surfaces, as well as to be used as a preventive of and as a general annihilator of combustion, more especially under certain conditions caused by great speed on railroads,where undue friction of parts occurs, usuallyin the use of new locomotives, en-

gines, cars, and trucks, that generally have.

rough journals and boxes, and require what is termed perfectly smooth set bearings.

In my Patent- No. 249,786, dated November 22, 1881, reference is made to the peculiar coating of car journals and boxes through the use and agency of crude unburned mica, owing to the larniuiferous or film property of the so-called mineral. In this my improved lubricant I'add to the mica finely-reduced wood -charcoal, or any other suitable refined carbon, and sal'soda, and from a series of very severe testiexperiments latelymade my improved lubricant seems to possess in its peculiar action what may be considered or termed an electrical magnetic or galvanic property or principle, or something similar thereto; for it has been discovered that the journals and boxes lately experimented with have a very smooth electroplating-like surface, in addition to the filling up of all inequalities or indentations of the axle and boxes, and because of the peculiarities of the carbon-'soda-mica combination the axle and boxes are never found to and of my Eureka lubricant eleven and onefourth pounds to run five thousand seven hundred and seventy-four miles, showing a most marked and important superiority of my improved lubricant.- This new composition of matter may be applied tojournals, axles, pistons, boxes, and steam-chests in the usual ordinary manner, with woolen or cotton waste or,

other fibrous packing, as required, and can be made more or less thick or thin, so as to be used in ordinary mechanical lubricating-cups or other receptacles, without the least possible difficulty or inconvenience, and alsomay be used, in a very thin or liquid condition, in suitable apparatus for suppression and complete extinguishment of combustion in cases of conflagrat-iou, thus possessing the twofold property of a lubricant and fire-annihilator; and, in addition to said purposes, it has been found that three of the substances of IIlly lubricant-via, carbon, sal-soda, and mica-wheu combined in themselves, apart from the other ingredients used, produce a powder-like substance which can be used for electrodes for electric light, and also for polishing metal surfaces, as well as for the packing of refrigerators, coolers, and packing-boxes.

I proceed herewith to give the following formula: Into a suitable wooden tank or vessel put eight (8) gallons ordinary paraffine-oil; put eight (8) gallons ordinary black-oil; put-four (4) gallons petroleum-residuum add t'hirty(30) pounds good clean thoroughly-reduced woodcharcoal or any other suitable= carbon;also twenty (20) pounds finely-reduced unburned crude mica. Next melt thirty (30) pounds good ordinary mutton-tallow, to which add live (5) pounds ordinary sal-soda,mixing well together all the foregoing substances. Into a separate mixing-vessel put six (6) pounds of clean beeftallow; add one and a half (1%) pound of concentrated lye, to which add eight (8) gallons of water. Then boil-thoroughly and'stir Well until the mixture assumes the consistency of ordinary honey. Then set this mixture aside to cool, and while cooling add five (5) pounds of ordinary sal-soda, thoroughly mixing and stirring the same, so as to prevent any settling or precipitation. Then proceed to combine all of the several ingredients by mixing them together in the mixing-machine, and then afterward run the Whole combined mass through an incorporating or reducing mill, from which the thoroughly-prepared lubricant will flow into suitable barrels, tubs. or tanks for storage and use. Larger quantities of the compound can be produced by increasing the amount of each ingredient, maintaining the same relative proportions as described in the foregoing formula, and observing the same manner or mode of mixingthe ingredients.

Another peculiar property of my improved lubricant is that changes of atmospheric temperature have little or no perceptible effect, for, alike in hot or cold weather, the compound remains of about the same uniform consistency-neither too thin or fluid to splatter or run, nor too thick, gummy, or sticky in its properties.

Having given the formula in full, with a 30 clear, exact description of the manner or mode of compounding my improved lubricant, and being aware that cannel-coal, mica, and salsoda have been heretofore used separately from each other as ingredients of different lubri- 5 cating compounds, I-d0 not therefore claim them in such condition; but

What I do claim, and desire to sew Letters Patent of the United States, i A lubricating compound composed of mica, I o charcoal, and sal-soda, in combination with I paraffine-oil, black-oil, petroleum-residuum, mutton and beef tallow, concentrated lye, and water, in or about the several proportions given substantially as set forth and described.

hi JOHN B. NORRIS.
