Description
Patented Nov. 29, 1932 UNITED STATES PATENT OFFICE LUBRICANT N Drawing.
This invention relates to a new and improved lubricant for railway track curves and locomotive or car wheel flanges. This class of lubricant is frequently termed flange oil by the railway trade.
Flange oil must adhere or stick tenaciously to metal track, or rail, even in the presence of steam, but it must be fluid enough to flow freely from the oiler.
1G I have found that the residuum produced by fractional distillation under approximately atmospheric pressure, in a pipe still equipped with an efl'icient fractio-nating tower, has the property of adhering very tea naciously to metal. The viscosity of this residual petroleum oil, which may range from about 1000 to about 6000 Furol viscosity at 122 F., is so high that said oil cannot be used alone as a flange oil.
I have also found that the product known as pressure tar, which is the residuum produced when petroleum products are cracked while subjected to heat and pressure, has the property of adhering tenaciously to metals. However, the viscosity of this product which may range from about to about 100 Furol viscosity at 122 F., is too low to be used alone as a flange oil.
I have discovered, however, that an ideal lubricant or flange oil with a Furol viscosity at 122 F. of 200 to 37 5 can be produced by blending the residuum from the pipe still distillation with pressure tar.
Usually it requires 20 to percent of pressure tar and to 60 percent of pipe still residuum to produce an oil which flows as desired. This invention, however, is not limited to the above percentages.
As an example of one form of this inven- 40 tion, I have made an excellent flange oil by blending said residuums to produce a product with 43 percent pressure tar and 57 percent of said pipe still residuum. An analysis of these two residuums is as follows:
Application filed January 25, 1930. Serial No. 423,558.
The blending of the foregoing products produced a flange oil with the following properties Gravity 13.6 Furol viscosity at 122 F. 249. L Sediment (A. S. T. M. method) 0.06% Flash (Cleveland open) 295 F. Fire (Cleveland open) 400 F.
It is understood that this invention is not limited to the foregoing specific example.
I claim:
1. A flange oil comprising a high viscosity residuum resulting from fractional distillation under approximately atmospheric pressure mixed with a low viscosity residuum resulting from a cracking operation.
2. A flange oil having a Furol viscosity between 200 and 37 5 at 122 F., said oil comprising more than 50 percent of a residuum having a F urol viscosity of more than 1000 at 122 F., and less than 50 percent of pressure tar having a Furol viscosity of less than 100 at 122 F.
3. An adhesive lubricant of the character described having a Furol viscosity between '5 200 and 375 at122 F., said lubricant comprising an adhesive residuum resulting from a cracking operation and having a Furol viscosity between 20 and 100 at 122 F. mixed with an adhesive residuum resulting from so fractional distillation under approximately atmospheric pressure and having a Furol viscosity between 1000 and 6000 at 122 F.
4. An adhesive flange oil of the character described having a Furol viscosity between 200 and 37 5 at 122 F., said oil comprising an adhesive residuum having a Furol viscosity between 20 and at 122 F. mixed with an adhesive residuum having Furol viscosity between 1000 and 6000 at 122 F.
5. An adhesive flange oil of the character described having a Furol viscosity of about 249 at 122 F., said oilcomprising an adhesive pressure tar having a Furol viscosity of about 30 at 122 F. mixed with an adhesive pipe-still residuum having a Furol viscosity of about 1875 at 122 F.
In testimony that I claim the foregoing I hereunto aflix my signature.
HARRY T. BENNETT.
