,To'. all 107mm it'may'c onca-rni it known that- I, James F;- Gauss afreside'nt of .Pittsbur 11, int 1e county of Allegheny and State Q Pennsylvania, have inrented anew and useful Improvement in Methods of Lubrrcatlng Bearings, of which the following is a specification.

The object of the inve'ntionis to provide the necessary su )ply of lubricant in a nian ner which absolutely pret'ents any dirt, dust or grit entering the bearings with-thelubrican't, or, .inother words, preventing the 15,

' portation, handling: or storage. or in sup-l lubricant itself, ,in any stage of its transplying the same to the bearing, from coming putting the" lubricant up; 'Fig. -2"-is. a'sec'w in contact witl dirt or grit. I 1

The invention comprises the process steps for supplying the lubricant scribed and claimed.

- In the accompanying draw'ing, 'F igur e 1' is a sectional view showing one manner of tiona. .view through a suitable grease "cup for receiving the package of lubricant; and F1 3 15B s1m1lar'y1ew'show1ng the man-.

Greases are usually put up in cans or other large receptacles, .or, infthecase of fairly solid greases, they are put up. n the form rOf small cylinders 'orcandles. The latter accumulate more or less dirt, soth'at when placed in the grease cup, this'idir'tis :fedinto the hearing.

Whenput up in cans or other large recep- 'tacles, thegrease must be put into the cup some crudenianner, which. generally re-. sults'. in more orless dlrt or dustentering with'the grease, The consequence 1s ihatthe bearings-are unnecessarily worn on account ot'the dirt and dust entering with the grease. According to my invention, the gre'ase or dther lubricant. indicated at 1 is put 'up at the; factory in small packages suitable for 3 entering .the grease .cup' without breaking ----the-same, by being'inclosed in a suitable.
