Barrel Staves as Springs for Play Auto
I made springs for a small foot-power automobile by using barrel staves joined together in the shape of pointed oval wagon springs. Two strong staves were nailed together at each end and braced with a block where they were nailed. Two of these springs were placed over the rear axle and one of them was set over the front axle extending in the direction of its length. The wooden springs made the automobile ride comfortably.—Charles Delbridge, St. Louis, Mo.
