Abstract: In a computer, keyboard, and flat-screen monitor support assembly a base is adapted to support a desktop-type computer housing thereon. A keyboard support tray pivotally is mounted to the base and extends outwardly therefrom. An upstanding support arm having a first end, and a second end, is attached to the base at one and to a flat-screen monitor at an opposite end. The opposite end of the support arm is spaced above the base to allow various differently sized computer housings to be positioned under the flat-screen monitor.

Abstract: An escapement mechanism for advancing a leading one of a row of gravity biased objects supported on a guide comprises a leading stop bracket and a trailing stop bracket pivotally mounted in fixed relation to one another and a piston and cylinder assembly, which pivots the two brackets. The brackets are angularly displaced relative to one another such that at one time, one stop bracket is in the path of the objects to back them up and the other stop is out of the path of said objects. The objects back up against the leading stop bracket and then the piston and cylinder assembly simultaneously pivots the trailing stop bracket into the path of the object immediately behind the leading object and pivots the leading stop bracket out of the path of the leading object to allow the leading object to advance by gravity beyond the escapement mechanism.
