(Fig. 5)
The nozzle is shown in Fig. 5. It can be made of iron or brass. The inside gradually tapers from 3/4 to 3/16 in. It has a 3/4-in. pipe thread and is screwed into the hole in the case from the inside and is secured with a lock nut. Enough additional threaded portion is left protruding to allow the supply pipe to be connected.
When assembling the motor, fasten the wheel to the shaft with the two setscrews, and place a metal washer, E, on each side of the wheel. Place the wheel in the casing and screw the cover plate in place. A thin rubber gasket should be placed between the cover and the casing to provide a water-tight joint.
The Motor as It is Coupled to Drive the Dynamo, and the Water Connections (Fig. 6)
The general arrangement of the plant is shown in Fig. 6. The motor and dynamo are mounted on a heavy wood base, which in turn is firmly bolted to a concrete foundation. Level up the two machines by the use of thin washers on the bolts between the base and machine. A heavy sleeve and setscrews are used to connect the two shafts. The connection to the water supply is made with 3/4-in. pipe, with a globe valve in it to regulate the flow of water. Any dynamo of about 100-watt output can be used.
Paper Shades for Electric-Light Globes
The appearance of an electric-light globe can be very prettily improved by making a shade of crêpe paper of any desired color for each one. Canary-colored crêpe produces a soft, mellow effect. Pale blue, yellow, red and, in fact, all the colors can be used, making a very pleasing variety.
