  • Patent number: 5246286
    Abstract: A tool cabinet is formed without the use of fasteners or weldments by providing back and side panel sections in an integral unit having top and bottom flanges, and separate top and bottom panel sections having attachment flanges adapted to be interfitted with the flanges on the back and side panel unit to form an open-front housing. Three continuous loop frame members are spaced apart front-to-back inside the housing and are adhesively secured to the top, bottom and side panel sections and support drawer assemblies mounted in a front opening. A lock bar guide is adhesively secured to the back panel section and receives a lock bar which is inserted through a notch in the bottom panel section after the housing has been assembled. Adhesive or frictional interengagement may also be used to secure together the flanges of the panel sections. An internal framework comprising a single, wide loop frame member with spaced-apart ribs is also disclosed.

  • Patent number: 4750440
    Abstract: A hoe-opener assembly having a "float" feature is disclosed. The present invention ties operation of several hoe openers to a common framework so that uniform depth control can be maintained. The hoe-opener assembly of the present invention is drawn behind an agricultural implement having a tool bar, and comprises a vertically movable framework. A frame lift-and-lower arrangement is provided for adjusting the spacing of the framework relative to the ground. The hoe-opener assembly includes a plurality of spring-biased hoe openers, each pivotally carried for limited pivotal movement by the framework at spaced intervals along the length thereof. A biasing-spring arrangement in operative association with each hoe-opener is provided whereby each hoe opener is substantially fixed against independent movement, relative to the framework.
