Springs on the Chains of a Porch Swing
Two coil springs of medium strength placed in the chains of a porch swing will make it ride easier and also take up any unpleasant jars and rattles occasioned when a person sits heavily in the swing. If the swing is provided with a four-chain suspension, the springs should be used on the two rear chains to get the best results.—Contributed by E. K. Marshall, Oak Park, Illinois.
Homemade Water Meter
Where it is necessary to measure water in large quantities the meter illustrated will serve the purpose as well as an expensive one, and can be made cheaply. The vessel, or bucket, for measuring the water is made diamond-shaped, as shown in Fig. 1, with a partition in the center to make two pockets of a triangular shape, each holding 2 qt., or any amount of sufficient size to take care of the flow of water.
