  • Patent number: 4042985
    Abstract: In an electrically or manually operated automatic bed making device, rollers are rotatably positioned at spaced opposite first and second ends of a mattress on a bed spring. A bed sheet and a bedspread are removably affixed to each other to form an endless loop and the loop is mounted on the rollers in a manner whereby part of the loop is on the upper surface of the mattress and part of the loop is beneath the bed spring. A pillow is removably affixed to the bed sheet. A blanket is removably affixed to the bed sheet. A motive device drivingly coupled to the rollers selectively rotates the rollers to selectively move the bedspread or the combined sheet, pillow and blanket onto the upper surface of the mattress and simultaneously move the combined sheet, pillow and blanket or the bedspread beneath the bed spring thereby selectively dressing the bed for non-use and preparing it for use.
