Abstract
Abstract An indicating shipping accelerometer having a transparent tube within which an inertial mass moves indicators relative to a scale affixed to the transparent tube to give an indication of the maximum shock incurred in either direction of its longitudinal axis. Springs on either side of the inertial mass maintain the inertial mass in its initial position. The unit may be reset for reuse by inserting a wire through the endcaps and repositioning the indicators.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
108 words
An indicating shipping accelerometer comprision: (a) a transparent tube which serves as a housing; (b) a ball which serves as an inertial mass within said housing capable of being longitudinally displaced within said housing; (c) a spring on both sides of said inertial mass, to urge said inertial mass into an undisturbed position; (d) an indication means which is visibly disposed within said housings, and which is displaced by said inertial mass, and which retains the maximum displacement of the inertial mass; (e) a scale which is used to measure the displacement of the indicating means within the housing; (f) end-caps which close the ends of said housing.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
46 words
An indicating shipping accelerometer according to claim 1 further comprising a strip of double sided adhesive tape, one side of which is secured to the indicating shipping accelerometer and the other side of which can be used to secure the indicating shipping accelerometer to another surface.
