3077 1 ' Folding Lever Key, steel throughout. 1/6 each, black ; 2/3 each, nickel-plated. 



This key is principally sent out with hired cylinders. When the lever is extended, an increased power is 

 obtained for opening the valve. When closed an ordinary T handle is formed, thus giving reduced leverage for 

 closing the valve, thereby preventing injury to the valve seating. The construction also prevents the valve 

 spindle being turned the wrong way in opening or closing the valve.

 round the valve spindle. Cylinder owners should possess one, but it is not supplied with hired cylinders.
