A pleating machine () is provided which allows extremely rapid, uniform pleating of flexible, tubular bodies (), thereby eliminating the arduous and time-consuming task of manual pleating. The machine () includes an upper, stationary, female tubular jaw () and a lower, reciprocal, male tubular pleating jaw () which are oriented in superposed, substantially axial alignment, along with a drive assembly () serving to vertically reciprocate lower jaw (). An elongated rod-type body support () extends downwardly through the upper jaw () and presents a pleating surface (), so that upon reciprocation of lower jaw (), the jaw lugs () successively engage the body () to form pleats (). The pleats () are retained by keeper structure including inwardly extending female jaw segments () and weighted slide () mounted on support ().

An improved crew oxygen mask and stowage assembly combination ( ) is provided including a stowage box ( ) equipped with a door ( ), with a crew mask assembly ( ) made up of a mask ( ), gas-conveying tubing ( ) and valve unit ( ). The box ( ) also includes a valve-controlling switch lever ( ) for selective gas-on or gas-off operation of valve unit ( ). In normal conditions, the mask ( ) and tubing ( ) are stowed within box ( ) with lever ( ) oriented in the gas-on position, so that the tubing ( ) is pressurized and mask ( ) may be quickly pulled from the box ( ) and used. After such use, the switch lever ( ) is shifted to the gas-off position, causing the tubing ( ) to be depressurized; this allows easy restowage of the tubing ( ) and mask ( ) within the box ( ). However, when door ( ) is closed, the switch lever ( ) is cammed back to the gas-on position, thereby repressurizing tubing ( ) and returning the combination ( ) to a full-ready condition.
