Such mirrors can be the only means for the operator of said vehicle to view his surroundings to the sides and to the rear of the vehicle while operating of said vehicles.

Description
2~39933 DESCRIPTIO~l OF TflE PRIOR ART
Side mounted rear view mirrors are extensively used on trucks and the like and an unrestricted view in such mirrors is essential for safe operation however, rain, calcium, snow and the like inhibit such unrestricted view. Various wiper arrangements for rear view mirrors have been proposed including the use of a laterally moveable wiper blade in conjunction with a side-mounted rear view mirror which moves in a oscillating reciprocating linear movement. However to the best of the present applicants knowledge, such wiper devices have been actuated with cumbersome drive motors and complicated linkages which are expensive to manufacture and excessive in weight.
Since these side mounted rear view mirrors are extensively in use it is desirable to have a wiper device easily adapted and mounted to these mirrors. It is further desirable to have said device as lightweight a~ possible as not to add undesired weight and strain to mirror supports. It furthermore should take advantage of the vehicles fluid pressure, such as compressed air, to power said wiper device not in an oscillating linear movement but more effectively in a two stroke per cycle reciprocating linear movement. Due to the fact that the reflective surface of the mirror assembly does not face the direct air flow when the vehicle is in motion. It should further be cost effectlve to manufacture, simple in design, ease of assembly and reliable in operation.
Summarv of the invention According to the invention, in its broader aspects and forming a primary objective thereof, a fluid pressure operated rear view mirror wiping device, of the such that may utilize its structural components for the support of the means to work reciprocating movement of the such re~uired to wipe a reflective surface of the such as rear view mirrors used on trucks and the like.
Another objective of the invention is to provide said invention with means to be adjustable and mountable to all conventional mirrors already installed and widely in use.
2 ~ 3 3 A further objective of the invention, in the inventors opinion, that unlike the wind shield the mirror would not require an oscillating reciprocating movement to clean the reflective surface but rather a two stroke, per cycle, reciprocating movement. Said cycle will become more apparent.
A more particular objective of the invention is to provide a fluid pressure operated, such as compressed air, rear view mirror wiping device such as contained in a stationary cylinder housing connected by means to the mirror housing, said cylinder housing containing a piston, having a piston rod slidably and sealed by means through one end of the cylinder head. Fluid supply means lead into the cylinder heads to provide fluid pressure to fluid drive surfaces between the piston and the cylinder housing. The piston having opposite fluid drive surfaces for driving said piston in a reciprocating cycle. Valve means control the reciprocating movement when arranged and connected by means to fluid pressure (such as in a trucks compressed air means) said valve normally in an open position supplies fluid pressure to the head & cylinder which drives the piston to the retracted, resting or off position. When said valve means are actuated, fluid pressure in the pressured side of the cylinder exhaust through the valve means and the supply fluid pressure is introduced to the opposite piston drive surfaces to drive said piston, piston rod, wiper arm and wiper arm means to the full extension or length of stroke. When valve means are returned to the original, resting or off position thus exhausting fluid pressure through the valve means and introducing fluid pressure to the opposite cylinder head and drive surfaces to drive said piston, piston rod, wiper arm, wiper arm means and wiper blade to the full retracted, resting or off position.
In carrying out these objectives the mechanism is simple in design, inexpensive to manufacture, reliable and rugged in operation.
The invention will be better understood and additional objectives and advantages will become apparent from the following description taken in connection with the accompanying drawings.
