Figure 3, throughout a distance sufficient to move
the piston 43 to the right far enough to unseat
the diaphragm ¿i2 from the seats 38 and 39. This
movement of the head 5| also causes the float 51

The major portion of the water thus delivered

of such movement is limitedby a coil spring 15
which is under compression between the lug 12

adjustment of the screw 19 the degree of com
pression of the spring 15 can be regulated, thereby
making possible variation oi the distance through
which the rocking head 5I can rotate in response
to downward movement of the iioat 51. In this
