Abstract
Abstract A vehicle-actuated air compressor and a system are disclosed for utilizing compressed air to operate an electrical generator to generate electricity. The vehicle-actuated air compressor includes an actuator, a cylinder, and a piston in the cylinder reciprocatable in response to actuation of the actuator by a vehicle for compressing air in the cylinder. The cylinder is provided with a first vent means for introducing air into the cylinder behind the piston during a forward stroke of the piston, a valve-controlled second vent means for introducing air into the cylinder on the other side of the piston during the reverse stroke thereof, and outlet means for supplying air compressed by the piston during the forward stroke thereof to a utilization device. In the system for generating electricity, the air compressor is combined with an electricity generator operated by compressed air to generate electricity, and at least one air storage unit coupled between the electricity generator and the outlet means of the cylinder for storing compressed air enroute to the generator. The air storage unit may be supplied with compressed air from other vehicle-actuated air compressors to provide a network for supplying compressed air to the air operated electricity generator. The vehicle may be land-borne or water-borne or both types may be used in one network.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
279 words
A vehicle-actuated air compressor comprising: actuator means operatively arranged for actuation in response to motion of a vehicle; a cylinder; a piston having forward and reverse strokes in said cylinder and operatively coupled to said actuator means for movement in response to actuation of said actuator means by vehicle motion for compressing air in said cylinder; first valve-controlled vent means for said cylinder communicating with one side of said piston for introducing air into said cylinder behind said piston during a forward stroke of said piston; second valve-controlled vent means for said cylinder communicating with the other side of said piston for introducing air into said cylinder on the other side of said piston during a reverse stroke thereof; first valve-controlled outlet means communicating with said other side of said piston for supplying air compressed by said piston during a forward stroke thereof to a utilization device; and second valve-controlled outlet means communicating with said one side of said piston for supplying air compressed by said piston during a reverse stroke thereof to said utilization device; said actuator means comprising: a body with a first slot therein extending longitudinally of the direction of vehicle motion; a lever slidable along said slot and projecting beyond said body for actuation by the vehicle to cause the lever to slide along said slot; and a flexible cable operatively connected between said lever and said piston to cause movement of said piston in response to movement of said lever; said slot having an offset at each end extending transverse to its length to permit movement of the lever out of the way of the vehicle as the latter moves past the air compressor.
Claim 2
Dependent Claim
279 words
A vehicle-actuated air compressor comprising: actuator means operatively arranged for actuation in response to motion of a vehicle; a cylinder; a piston having forward and reverse strokes in said cylinder and operatively coupled to said actuator means for movement in response to actuation of said actuator means by vehicle motion for compressing air in said cylinder; first valve-controlled vent means for said cylinder communicating with one side of said piston for introducing air into said cylinder behind said piston during a forward stroke of said piston; second valve-controlled vent means for said cylinder communicating with the other side of said piston for introducing air into said cylinder on the other side of said piston during a reverse stroke thereof; first valve-controlled outlet means communicating with said other side of said piston for supplying air compressed by said piston during a forward stroke thereof to a utilization device; and second valve-controlled outlet means communicating with said one side of said piston for supplying air compressed by said piston during a reverse stroke thereof to said utilization device; said actuator means comprising: a body with a first slot therein extending longitudinally of the direction of vehicle motion; a lever slidable along said slot and projecting beyond said body for actuation by the vehicle to cause the lever to slide along said slot; and a flexible cable operatively connected between said lever and said piston to cause movement of said piston in response to movement of said lever; said slot having an offset at each end extending transverse to its length to permit movement of the lever out of the way of the vehicle as the latter moves past the air compressor.
Claim 3
Dependent Claim
