vice and Fig. 4 is a cross-sectional 4 view of slide form- 

 ing portion of tripping device. 



The operation of the current motor is as follows: 

 The current coming in the direction of the arrows A 

 (shown in Fig. 1) strikes the blade 7 at an angle. 

 This resolves the force into two components, one in the 

 direction of the swinging pendulum 8, which is re- 

 ceived by the pin 2, and the other at right angles to 

 the said pendulum, which causes the same to swing in 

 the direction indicated by the arrow B until the 

 slide 3 comes in contact with the bumper 4. The 

 bumperhead 5, striking against the said slide 3, carried 

 upon the pendulum 8, allows the said pendulum 8 to 

 swing underneath the slide 3 until the said pendulum 

 strikes against the limiting portion 1 of the said slide.

This movement swings the T-9 to the opposite side of 

 the pendulum 8, it being held in position by spring 10, 

 thereby maintaining in its changed position until the 

 pendulum again swings to the opposite bumper when 

 the operation repeats itself. Upon the slide striking 

 the bumpers and the T-9 being thrown over to the 

 other side of the pendulum, the links 11, 11, attached 

 to the other end of the T member 9, cause the blade 

 to swing in the opposite direction and to a reversed 

 position to that it had prior to the time when the 

 slide strikes the bumper; this always presents the 

 blade to the stream in such an angular position that 

 the force of the stream will be resolved into such com- 

 i ponents as will cause the blade and pendulum to swing 

 back and forth. The swinging motion is communi- 

 cated to pumping mechanism or other machinery by 



means of the connecting rod 12 connected to the pen- 

 dulum by the pivotecf member 13. All parts of this 

 machine are above water, thereby making it an easy 

 task to oil and keep in repair. It can be successfully 

 operated in shallow as well as deep water. It adjusts 



itself to the stage of water in the stream. This appa- 

 ratus is much less expensive than the other two de- 

 scribed devices; the device is manufactured by the 



t CHAW*"-' BUCKET 



Current Motor and Irrigation Company, S'pokane, 

 Wash. 



Besides the above described devices, there are many 

 others in use for lifting water, but they are very closely 

 constructed to one of the three named above.
