Abstract
A shipping strap assembly protects the isolator mechanism of a vibratory screening machine against exceeding its elastic limits. The isolator mechanism is pivotally connected between shafts on the machine frame and the machine basket. The protective assembly includes a distally narrowing boss on at least one of the shafts. A rigid strap has two apertures, one contoured to receive and ride on the boss and the other contoured to receive the other shaft, spaced to maintain the distance between the shaft axes within an elastic limit of the isolator mechanism. The narrowing boss provides leeway for easy manual alignment of the mechanism shafts with the strap apertures, and the narrowing boss and contour of the other aperture facilitate restoration toward its normal load length, of an elastically distorted mechanism.
