Patent number: 6804988Abstract: The present invention comprises an automated machine for testing the physical properties of spherical objects. Preferably, the apparatus comprises a firing mechanism that includes an inner and outer barrel. An object inside the firing mechanism is propelled towards a striking surface that faces the firing mechanism. Two sensors located at predetermined points between the firing mechanism and the striking surface measure the inbound and outbound velocity of the object. A computing device then uses an algorithm to determine the COR of a given set of objects. An angular device uses gravity to direct the objects to a retrieval chute, which uses a tubing system to direct the objects for re-testing or collection.Type: GrantFiled: May 5, 2003Date of Patent: October 19, 2004Assignee: Acushnet CompanyInventors: Michael P.
