LUBRICANT.
No mrawing.
The present invention relates to improvements in lubricants, and more partlcularly to lubricants adapted for use in bearings running at high temperatures, for example, roller-mill bearings, railway car bearings (hot boxes) and the like. Such lubricants are particularly adapted for use -in heated journal boxes, in the manner described in my co-pending application Serial No. 542, 492, filed of even date herewith.
in preparing a lubricant in accordance with the present invention, a fatty compound, preferably an oil or fat is employed asa base for the lubricant. For example, stearic acid, tallow, linseed oil, soya bean oil and the like, either alone or in admixture with resin, have been found to be suitable. The fatty compound is admixed with from to 25% of sulfur (preferably to and the mixture heated to a temperature in excess of 430 F. the preferred temperature employed depending to some extent upon the character of fatty compound used and is characterized by its high viscosity at high tempef ayures (above 49 seconds Saybolt at 300 temperature'in excess of 430 F., and preferably 450 to 460 F., has been found satis factory, whereas with linseed oil it has been founddesirable to carry the temperature of themixture to 610 F. or higher. A chemical reaction takes place between the fatty acid compound and the sulfur, resulting in the formation of a material having a relatively high viscosity at high temperatures such as prevail in hot bearings and hot boxes. The reaction product of the fatty acid compound with from 5 to of sulfurmay suitably be admixed with resin, petrolatum, graphite, lamp-black, or other modifying constituents.
For example, a mixture of 12 parts tallow, 4 parts sulfur, 2 parts resin and 9 parts graphite'wel'e heated to 430 F. to cause retemperature of the mixture being carried ultimately to 560 F. to complete'the reaction. The mixture, although solid at ordinary temperatures, provides excellent lubrication for hot boxes, ordinaryrailroad packing waste, for example, being saturated with the compound and packed into the hot boxes,
the cars involved immediately continuing their run. Excellent lubrication for the hot scribed may be omitted, if desired.
Thus, in the-\case of tallow, a
' air for 10 hours at 480 F.
Application filed March a, 1922. Serial No. 542,493.
The resin in the composition above de- 'lhe graphite, which may be replaced by lampbla'ck or other suitable" material, aids in smoothing the journal and bearing and to that extentassists in reducing friction. It
may likewise be omitted, if desired.
Linseed oil is preferred to tallow in preparing a lubricant in accordance with the present invention, since the resulting material remains liquid when cooled, has ahigher flash point, and wets or adheres better to the bearing surfaces. Other fatty acid compounds, such as soya bean oil, cottonseed oil, corn oil, and the like, may be em loyed.
The compounds formed in accor ance with the present invention are characterized in part by their high viscosity at high temperatures. For example, a lubricant containing 95% tallow and 5% of sulfur, heated to 500 F. to completion of reaction, which occurs in 20 to 30 minutes, has ahas a viscosity of 64 seconds at 300 F. and i 50 seconds at 400 F.. A compound of tallow; 75% and sulfur 25%, prepared by heating at 475 F., has a viscosity of 94 seconds at 300 F and 54 seconds at 400 F.
The viscosity of fatty compounds of the drying or semi-drying type may be raised by blowin subsequent to the incorporation of the sul ur. For example, linseed oil may be blown with air after it has been caused to react with 5 to 25%of sulfur, the blowing being carried out in the usual manner of linseed oil blowing; for-example, with A compound of linseed oil and sulfur 10%, heated for 15 minutes at 560 F., has a viscosity of 180 seconds at 300 F., 94'seconds at 400 action between the sulfur and the tallow, the
and 87seconds at 450 F. A compound of linseed oil 80% and sulfur 20% heated to 640 F. to completion of reaction, say 15 to 20 minutes, has a viscosity of 170 seconds at 300 F. and 79' seconds at 400 F.
The lubricant compound in accordance withthe present invention may, in use, be admixed with suitable mineral oil lubricants, such as heavy cylinder oils. Cylinder oils. suitable for this purpose have been prepared having fiash points of 57 5 to 610 ,F., and 184 to 350 seconds Saybolt viscosity at 212 F. Mixtures of the sulfur-combined fatty compound lubricants of the present invention with such cylinder oil have a higher load-bearing capacity over a wide range of tem raturcs than either constituent alone. Sue mixt-ures ma contain from 10 to of the sulfur-com ined lubricant.
From 10 to 40% of carbon in the form of graphite, lamp black, carbon black, or the like, is preferably added to the lubricant before use, for the purpose hereinbefore set forth.
