  • Self-aligning drawer slide tab
    Patent number: 4119377
    Abstract: A drawer slide having a pair of parallel slide members, one of the slide members having a roller at the end opposite the roller of the one member.The slide members are channel-shaped and oppositely arranged, with the roller of one slide member received in the channel of the other slide member, the rollers carrying each respective slide member. A resilient tab is lanced out of one of the slide members adjacent an end. When the slides are installed in a drawer or cabinet, one slide member is attached to the side of a drawer while the other slide member is attached to an adjacent part of the desk or cabinet drawer opening. The tab is turned inwardly of the slide member opposite the slide member having a roller at that end. The free end of the tab is at the free end of the slide member from which it is lanced out; and, when the slide members are retracted, the tab frictionally and yieldingly engages a part of the adjacent roller to take up any play between the two slide members.
