Abstract:
A acceleration resolver for use in an acceleration recorder to record the magnitude of acceleration said resolver experiences, said resolver comprising a housing, spindles extending orthogonally through said housing, disks having central apertures and eccentric apertures, said disks having markings about said central apertures, said spindles coaxially aligned with said central apertures, coil springs disposed around said housing, said coil springs having one end engaging said eccentric aperture and the other end fixedly connected to said housing, and an elongated indicator having one end movably connected to said housing and an intermediate portion extending over said disk above said markings and the other end located in said central aperture, said elongated indicator under spring tension against said disks, whereby acceleration applied to said impact recorder produces proportional rotation of said housing and said elongated indicator, and said spring tension between said indicator and said disk fixing said indicator at the limit of rotation.
