ABSTRACT:
A vibratory stress relief apparatus is provided and has a resiliently supported base and an adjustable rate vibratory member on the base. A housing having a support plate and spaced side walls is resiliently supported on the base. A casting rests in the housing with a closure secured to the support plate in spaced relation to the casting. Shims are provided for positioning the closure a predetermined distance from the casting whereby the vibratory member will vibrate the housing and the casting and will hammer and rattle the casting between the closure and the support plate to relieve stresses in the casting and to clean sand and other impurities from the internal and external surfaces of the casting.
