Claim 1
Independent Claim
216 words
A remote-control truck mirror comprising, an air-actuated cylinder, piston and rod means carried by said cylinder providing a means for rotating said mirror, arm means carried by said mirror for connecting said mirror to said rod means, first internally threaded cap sleeve means carried by said cylinder for closing off one end of said cylinder and a second internally threaded cap carried by said cylinder for closing off the opposite end of said cylinder, said second cap having a central hole permitting longitudinal movement of said rod means, mounting bracket means carried by said cylinder for holding it in position on a truck cab, spring means carried within said cylinder in compression between said piston and said second cap means providing return means for said mirror to its normal position, regulator valve and control valve means located remote from the mirror in the truck cab, an air line for carrying air from said valve means to said air-actuated cylinder for moving said piston toward said second cap against the action of said spring means, and an air vent valve including aligned openings in said cylinder and said first cap sleeve means to permit escape of air and allow the piston and thus the mirror to be returned to its normal position by action of said spring.

Claim 3
Dependent Claim
117 words
The combination according to claim 1, wherein said mirror is vertically mounted between a pair of outwardly extending rods, the rods being secured to brackets which are fastened to the cab wall of the truck, said rods being secured to said brackets by bolt and nut fasteners, and said mirror is provided with centraL pins at each end, said pins being received in said rods and held in place pivotably by suitable nut fasteners, and one end of said mirror frame is provided with an offset and extending arm, said arm being freely carried upon an upright pin projecting from said piston rod, said pin being threaded at its outer extremity and receiving a suitable nut fastener.
Claim 4
Dependent Claim
99 words
The combination according to claim 2, wherein said piston rod travel inwards of said cylinder is limited by means of a stop adjustment nut threadingly carried upon the extending portion of said piston rod, and said stop adjustment nut allows said mirror to return to its normal position after being actuated, said nut being secured in a desired position by means of a setscrew threaded into said adjustment nut, said piston rod being slideably received in an externally threaded bushing, said bushing being threaded into said second cap of said cylinder and said bushing receiving a pair of locknuts.
