ON SPHERE AND ROLLER MECHANISM FOR TRANSMITTING POWER. 489 



The bearing is first adjusted by means of the screw (d), which has 

 a large flat head, forcing the bush (a) in, and taking up all the slack on 

 the conical part of the bearing. The set screw (c) is next turned until it 

 takes all the end thrust on the shaft (6). The bush is now locked by 

 means of the set screw (p). This makes a very efficient though expensive 

 bearing.

Figs. 6 and 7 illustrate the manner in which an oil bath was applied 

 to the bearings of the driving-shaft in fig. 3. The shaft in question 

 works under a pressure of about 1,200 lbs., the size of the bearing being

3" diameter by 1;^" wide, the surface speed of the journal being about 

 150 feet per minute. Referring to the figure, s is the shaft, a the cast- 

 iron bearing, the surface of s is also cast iron. A light brass framing 

 with leather lining is attached to the bearing (a) by the flanges (b b b), 

 and makes a joint round the shaft at cccc. The chamber e contains the 

 oil. This bearing has worked continuously without heating, and gives 

 most satisfactory results, the only defect being a slight leakage of oil 

 round the flanges cccc, fig. 7 ; the amount is, however, very small. It 

 -was designed from data given by Mr. Beauchamp Tower in his account
