20090107687 | FIRE-FIGHTING MONITOR - A fire-fighting monitor includes a first body having an internal passageway defining an inlet and an outlet, a coupler having an internal passageway defining an inlet and an outlet, the coupler being pivotally mounted to the body at the outlet of the body wherein the internal passageway of the coupler is in communication with the internal passageway of the body, and the coupler having at least one pivot axis. Further, the monitor includes a counterbalance device, which comprises an annular member mounted to the first body at the pivot axis. The counterbalance device further comprises a pivot member mounted to the coupler and a second unitary body mounted about the pivot member, with the second unitary body being adapted to engage and generate an interference with an inner surface of the annular member when the coupler is pivoted about the pivot axis in a first direction and adapted to release the interference with the inner surface of the annular member when the coupler is pivoted about said pivot axis in an opposed second direction from the first direction. | 04-30-2009 |
20090236446 | NOZZLE ASSEMBLY - A nozzle assembly includes a nozzle body with an inlet, an outlet, and a passageway extending from the inlet to the outlet, and with the passageway having a flow area and a fixed diameter at the outlet. A lever is supported at the nozzle body, and the nozzle assembly further includes an actuator, which is supported by the nozzle body and configured for varying the cross-section of the flow area through the outlet in response to the lever being moved relative to the nozzle body. | 09-24-2009 |
20090301735 | REMOTE CONTROLLED NOZZLE CHANGER - A fire fighting fluid delivery device includes a device body with an inlet, a discharge outlet, and a fluid passageway extending between the inlet and the discharge outlet. A movable member is mounted at the body and movable between at least two positions relative to the outlet. The movable member includes at least two spaced apart transverse openings, with each of the transverse openings for selectively aligning with the discharge outlet when the movable member is moved between the at least two positions. | 12-10-2009 |
20090321091 | FIRE-FIGHTING MONITOR WITH REMOTE CONTROL - A high pressure monitor includes an outlet body with a transverse passage, which extends through the body to form two inlets of the outlet body, and a second passage, which is in communication with the transverse passage and extends through the outlet body to form an outlet. The monitor further includes first and second bodies, with the outlet body mounted between the first and second bodies. Each of the first and second bodies has a transverse passage, which are in fluid communication with the inlets of the outlet body. A first swivel joint is provided between the outlet body and the first body. A second swivel joint is provided between the outlet body and the second body. Further, each of the swivel joints comprises a pressure balanced hydraulic fitting with seals and bearings, wherein the seals and bearings are oriented to reduce the axial pressure on the bearings from fluid flowing through the monitor. | 12-31-2009 |
20100038900 | SWIVEL CONNECTION FOR A FIREFIGHTING DEVICE - A fluid delivery device has a fluid delivery device body with an inlet, an outlet, and a passageway extending from the inlet to the outlet, with a first annular seal located at the inlet. An annular fluid connection member has a threaded portion adapted to threadably attached to a fluid supply conduit where an annular second seal is optionally located. An intermediate member is located downstream of the fluid connection member and engages the first seal. The intermediate member is rotatably mounted to the fluid delivery device body at the inlet and to the fluid connection member at a location upstream of the inlet. The fluid connection member, intermediate member, and fluid delivery device body are each independently rotatable with respect to one another. | 02-18-2010 |
20100274397 | FIREFIGHTING MONITOR AND CONTROL SYSTEM THEREFOR - A firefighting monitor system includes a monitor, a controller selectively generating signals to the monitor for controlling the monitor, and a computer. The computer is configured to receive input from a user relative to the monitor or the controller. The computer generates an output based on the input, and the output is transmitted to the controller for controlling the monitor or the controller in accordance with the output. | 10-28-2010 |
20130119167 | FIRE-FIGHTING MONITOR WITH REMOTE CONTROL - A high pressure monitor includes an outlet body with a transverse passage, which extends through the body to form two inlets of the outlet body, and a second passage, which is in communication with the transverse passage and extends through the outlet body to form an outlet. The monitor further includes first and second bodies, with the outlet body mounted between the first and second bodies. Each of the first and second bodies has a transverse passage, which are in fluid communication with the inlets of the outlet body. A first swivel joint is provided between the outlet body and the first body. A second swivel joint is provided between the outlet body and the second body. Further, each of the swivel joints comprises a pressure balanced hydraulic fitting with seals and bearings, wherein the seals and bearings are oriented to reduce the axial pressure on the bearings from fluid flowing through the monitor. | 05-16-2013 |
20140094976 | FIREFIGHTING MONITOR AND CONTROL SYSTEM THEREFOR - A firefighting monitor system includes a monitor, a controller selectively generating signals to the monitor for controlling the monitor, and a computer. The computer is configured to receive input from a user relative to the monitor or the controller. The computer generates an output based on the input, and the output is transmitted to the controller for controlling the monitor or the controller in accordance with the output. | 04-03-2014 |
20140209329 | MECHANICAL REMOTE MONITOR CONTROL - A system and method remotely mechanically controls the direction of fluid flow from a firefighting monitor. For example, a control handle mounted in the cabin of a vehicle can be operably mechanically coupled to a pivotable firefighting monitor mounted outside the vehicle (e.g., near the front) by an arrangement of cables. The handle and cables are arranged such that horizontal pivoting of the handle results in a corresponding horizontal pivot of the firefighting monitor, and vertical pivoting of the handle results in a corresponding vertical pivot of the firefighting monitor. The direct mechanical link between the handle and firefighting monitor ensures a rapid and reliable control over the monitor direction and orientation, while providing an intuitive and user friendly operational modality. | 07-31-2014 |
