Publication number: 20070034389Abstract: A novel aerial boom system for use atop a vehicle and having linear movement sensors associated with hydraulic cylinders for moving lower and upper booms such that a microprocessor associated with the system can determine the instantaneous position of each boom and coordinate movement of the booms with respect to each other and with the vehicle to prevent undesired contact and to gradually decelerate boom movement as the boom approaches its limits to avoid shock from sudden stop of boom movement. When the novel system is used with a fire fighting vehicle, two variably spaced, independently controllable, fluid discharge nozzles can be used to fight one or two separate and distinct fires simultaneously. A piercing nozzle can be associated with the outer end of the upper boom that is independently controllable in both the vertical plane and in the horizontal direction to enable piercing of a wall independent of boom movement to assist penetration.Type: ApplicationFiled: August 10, 2005Publication date: February 15, 2007Applicant: Crash Rescue Equipment Service, Inc.Inventors: Robert Relyea, Grady North

Publication number: 20060032939Abstract: A management system for controlling the dispensing of a fire fighting agent from a container in which a control device is used to select a desired rate of discharge of a fire fighting retarding agent from a container. The system includes a display in visual proximity to a user of the control device for visually indicating the selected flow rate of the fire retarding agent from the container. In addition, the system includes a visual display for indicating the time remaining, preferably in minutes and seconds, for the fire retarding agent in the container to be substantially completely expended. Alternatively, a synthesized voice may announce the time remaining at predetermined intervals such as every 5 seconds. Finally, a visual display, preferably in the form of a bar graph, gives the real time physical level of the fire retarding agent remaining in the container at any given time.Type: ApplicationFiled: August 10, 2005Publication date: February 16, 2006Applicant: Crash Rescue Equipment Service, Inc.Inventors: Robert Relyea, Grady North

Patent number: 5899276Abstract: A forward-mounted fluid-dispensing boom on a fire-fighting vehicle that can move between a retracted position and a fully extended position directly in front of the vehicle.Type: GrantFiled: September 10, 1997Date of Patent: May 4, 1999Assignee: Crash Rescue Equipment Service, Inc.Inventors: Robert G. Relyea, Grady C. North

Patent number: 5839664Abstract: A fluid discharge nozzle assembly that has both a piercing nozzle for fighting fires behind a wall member and a foam/spray nozzle for applying fire-retardant fluid to an open fire. The piercing nozzle is movable only in a vertical plane. The foam spray nozzle is movable in both the vertical plane with the piercing nozzle and in a direction perpendicular to the vertical plane so that, when the piercing nozzle is to be used, the foam/spray nozzle is movable to a position perpendicular to the longitudinal axis of the piercing nozzle to provide maximum clearance of the piercing nozzle during use of the piercing nozzle.Type: GrantFiled: July 31, 1996Date of Patent: November 24, 1998Assignee: Crash Rescue Equipment Service, Inc,Inventor: Robert G. Relyea

Patent number: 5788158Abstract: An automatic levelling device for a fluid nozzle pivotally mounted on the outer end of an aerial boom such that, irrespective of the vertical position of the boom, the nozzle will remain in a horizontal plane. Either manually operated control of the fluid nozzle vertical position or automatic control that maintains the fluid nozzle in a horizontal plane can be selected by a switch.Type: GrantFiled: July 31, 1996Date of Patent: August 4, 1998Assignee: Crash Rescue Equipment Service, Inc.Inventor: Robert G. Relyea

Patent number: 5301756Abstract: An aerial boom system for a fire-fighting vehicle which has a hollow piercing nozzle on the outer end thereof for passing through the wall of a structure such as an aircraft fuselage to the interior of the structure where a fire-retardant material may be injected. The nozzle may pierce the fuselage from a remote distance because of the extensible boom. It has thereon a torque limiter to protect the nozzle assembly when forces are applied to the nozzle assembly in a direction transverse to the piercing direction.Type: GrantFiled: February 8, 1993Date of Patent: April 12, 1994Assignee: Crash Rescue Equipment Service, Inc.Inventors: Robert G. Relyea, Edward V. Garnett

Patent number: 5211245Abstract: An aerial lift for use with a vehicle for positioning the nozzle on the outer end of an upper boom coupled at its inner end to the outer end of a lower boom with selectively raising and lowering the lower boom in a plane from and above the horizontal and rotating the lower boom about a vertical axis, and independently articulating the upper boom about its inner end with respect to the lower boom such that the upper boom is selectively movable above and below the horizontal plane.Type: GrantFiled: July 1, 1991Date of Patent: May 18, 1993Assignee: Crash Rescue Equipment Service, Inc.Inventors: Robert G. Relyea, Edward V. Garnett
