US Patent:

6382869, May 7, 2002

Filed:

Dec 9, 1999

Appl. No.:

09/458165

Inventors:

Harry D. Dickinson - Valencia CA 91355

International Classification:

E01F 1302

US Classification:

404 6, 49 9, 49 34

Abstract:

An above-grade trafficway barrier adapted to arrest heavy vehicles, with an obstruction member extending between opposite sides of the trafficway, and controlled by its known mass deposed upon the grade level and preferably by spaced inertia blocks deposed at opposite sides of the trafficway, the known mass not to exceed the strength of the obstruction member and coupling thereof regardless of the vehicle mass. Impact force being gradually applied and dissipated by the known mass through a lever system with simultaneous roll, turn and sliding movements of said spaced masses; whereby the obstruction member is not subjected to greater force exerted by the impacting vehicle.

Appl. No.:

7/065558

Inventors:

Harry D. Dickinson - Glendale CA

International Classification:

E01F 1300

US Classification:

404 6

Abstract:

A semaphore type trafficway barrier for arresting vehicles, and comprised of spaced posts at opposite sides of the trafficway, one a pivot post disposed on a vertical axis and with a yieldable mounting rotatable plate on the post to carry a beam to swing between an open ineffective position to a closed effective position as well as to yield to impact, and characterized by a cable anchored to the pivot post and carried by the beam with an end engaged over a bit on the other post at the opposite side of the trafficway.

Filed:

Mar 6, 1981

Appl. No.:

6/241025

Inventors:

Harry D. Dickinson - Glendale CA

International Classification:

E01F 1300

US Classification:

404 6

Abstract:

A motorized traffic-way controller wherein a retractile curb barrier and locking lift means operate by motor drive means that is recycled by closing a mode switch through cam controlled "stop" and "go" switches responsive to the position of a motor drive means at the side of the traffic-way, the preferred installation being above grade and comprised of low profile modules with retractile curb configurations that project as tire barriers, the modules and drive means being adapted to coupled engagement one with the other when assembled.

Filed:

Feb 27, 1998

Appl. No.:

9/032301

Inventors:

Harry D. Dickinson - Valencia CA

International Classification:

E01F 1312

US Classification:

404 6

Abstract:

A vehicle trafficway controller characterized by a person friendly driver intimidating wrong-way traffic condition for causing vehicle tire tread damage, having a vertically extensible tire tread piercing member shiftably carried by a frame and with a retractile tread piercing point, and a movable person protective cover isolating said point when in said person friendly driver intimidating wrong-way traffic condition, and exposing said tire tread piercing point to a tire tread rolling thereover, the tire tread piercing member being frangible and/or extended and retracted.

Filed:

Apr 25, 1983

Appl. No.:

6/488106

Inventors:

Harry D. Dickinson - Glendale CA

International Classification:

E01F 1300

US Classification:

404 6

Abstract:

A vehicle traffic-way controller of retractile barrier configuration wherein activation and control is by hydraulics in the form of a pressure source applied from a motor driven pump and directed by a valve to opposite ends of a double acting cylinder and piston actuator to extend and retract the barrier, there being switch control with positive positioning of the barrier and with impact absorbing protection for the hydraulics and structure.

Appl. No.:

6/840389

Inventors:

Harry D. Dickinson - Glendale CA

International Classification:

E01F 1300

US Classification:

404 6

Abstract:

A bollard type trafficway barrier for arresting vehicles, comprised of a cast in place foundation and a bollard replaceable therein with a spring for lifting the bollard that is directionally oriented with respect to traffic so as to withstand great impacts, and with access for replacement of the bollard, with retraction by manual depression and extension by instantaneous release of potential energy stored in said spring, the bollard being locked in both the retracted and extended conditions, and installation being flush with the grade when retracted and the bollard being released manually or power controlled from a remote location by a vehicle sensor.

Appl. No.:

5/916207

Inventors:

Harry D. Dickinson - Glendale CA

International Classification:

E01F 1300

US Classification:

404 6

Abstract:

A visible traffic controller permitting one-way and preventing wrong-way flow of vehicle traffic, and including a safety feature for the prevention of serious bodily injury to persons who might accidentally encounter the same, and comprising retractile barrier blades operated to functional position by noninjurious levers raised by soft spring action to be encountered by a vehicle tire in both the one-way and wrong-way directions of flow, and operable by a vehicle moving in the later direction to damage its tires.

Appl. No.:

6/160945

Inventors:

Harry D. Dickinson - Glendale CA

International Classification:

G08G 102
E01F 1100

US Classification:

340127

Abstract:

A motorized traffic-way controller wherein a retractile tire barrier and opening gate barrier are coordinated to operate in unison by a motor drive that is recycled by closing a mode switch through cam controlled "stop" and "go" switches responsive to the position of the motor drive, the installation being above grade with low profile modules having retractile tooth configurations that projects for tire damage, and with a signal barrier supported by a drive unit at the side of the traffic-way and in the form of an arm that is lifted when the tooth configuration is retracted, the modules and drive unit being adapted to coupled engagement one with the other when assembled.
