Abstract
Loaded article carriers of the basket style are tested by engaging the handle of the carrier with hanger means secured to a suitable gauge mounted on a ram which is driven upwardly by motive means in such manner as to cause the articles to engage a fixedly mounted stop plate and thereby to simulate a gradually increasing load on all critical parts of the carrier the magnitude of which is indicated by the gauge.

Apparatus for testing a loaded basket style article carrier having an article receiving basket section depending from a handle section and a plurality of articles disposed in said basket section, said apparatus comprising a frame, stop plate means affixed to said frame and having aperture means for receiving the carrier handle with the carrier basket section and the articles therebelow, ram structure movably mounted on said frame, gauge means mounted on said ram structure, coupling means engageable with the carrier handle and with said gauge means, and motive means arranged to react between said frame and said ram structure and operable to impart relative movement thereto so as to cause the articles in the carrier to engage said stop plate means thereby to impart a simulated gradually increasing loading force to the carrier handle and basket sections the magnitude of which is indicated by said gauge means.
Apparatus for testing a loaded basket style article carrier having an article receiving basket section depending from a handle section and a plurality of articles disposed in said basket section, said apparatus comprising a frame, stop plate means affixed to said frame and having aperture means for receiving the carrier handle with the carrier basket section and the articles therebelow, ram structure movably mounted on said frame, means including coupling means engageable with the carrier handle for interconnecting the carrier handle with said ram structure, and motive means arranged to react between said frame and said ram structure and operable to impart relative movement thereto so as to cause the articles in the carrier to engage said stop plate means thereby to impart a simulated gradually increasing loading force to the carrier handle and basket sections.
A method of testing the mechanical strength of a basket style article carrier having bottom, side and end walls and a handle secured to the carrier end walls, the method comprising loading the carrier with articles, restraining the articles in such manner as to prevent movement thereof in a direction away from the carrier bottom wall, imparting a gradually increasing force to the carrier handle in a direction away from the carrier bottom wall until the carrier fails mechanically.
