on surfaces such as aircraft wings fig1 b shows a universal adapter plate assembly 10 this assembly is fabricated by welding a tubular coupler 13 to a sheet of aluminum 2 inches wide by 8 inches long by 1 8 inches thick multiple holes are drilled in plate 73 to allow attachment to a wide broom head rubber squeegee or other device required by special situations fig1 a to 12f show a number of driver handle embodiments the main driver handle 60 shown in fig1 c is formed from 1 inch outside diameter aluminum pipe six feet long with a d handle to allow for secure grip especially when using the device in the pulling mode the diameter of the tubing allows an easy clearance fit into the tubular attachment 13 this handle form is the preferred handle for most applications the handle 60d shown in fig1 d has a simple grip and is used in a similar manner except it is lighter and considered to be for less severe duty applications the drive handle 60 may be bent as shown in fig1 a and 12b in fig1 a the handle is bent to form angle u03b8 of 30 degrees fig1 b shows a handle 60 set to an angle u03b8 of 45 degrees the handle shown in fig1 a is best suited for use on shallow pitched surfaces or in snow conditions requiring more directed thrust while the handle shown in fig1 b is more suited for elevated flat.
