such matter. ‘An object‘ of the present int/‘en;tion is’ to provide a construction in which the’
glass is movable and the wiper is stationaryg-thus
obviating the necessity for a'reciprocable'or ‘other,
10 movable member to sweep acrossth'e surfalc‘eof
the glass; which member, especially in conneee
tion with a windshield, tends to confuse-the driver
and obstructs his vision.

It is also any object to secure a' better and
15 more positive cleaning action over a more e’xtended area and to provide ‘an arrangement
whereby substantially the entire area 7 off’ the‘
windshield glass may be wiped‘c'lea‘niand maintained in that condition.

member to sweep the entire surface of the movable glass, said member being mounted for hand
25 manipulation where the glass is rotated, so that
said member may be shifted out of contact therewith when rotation is discontinued, or may be
manipulated to sweep across the glass when the
glass is held stationary; and also to provide
30 an arrangement of drive for the glass whereby
the glass framing may be'pivotally mounted to
swing to open position for the purpose of ventilation.

from the outside face of each glass diskli, a
wiper 9 is provided for each of these glass disks,
the wiper being preferably mounted at the lower
side of each disk and held in a ?xed position 25
against the surface of the disk. Each of these
wipers 9 is pivotally attached at I 0 to the upper
end of a rod II which is secured at its lower
end by a head l2 to the forward end of a shaft

below each of the openings 2 which are closed
by the disks 6 and on the inner end of this
shaft I3 is a handle M by means of which the
shaft may be turned to swing the Wiper about
