Patent number: 11795048Abstract: A leak stop assembly for an automatic shut-off fluid nozzle having a fluid flow path and a check valve with a through bore in the flow path. The assembly includes a bleeder seat that houses a length of the flow path proximate the check valve, a rubber plug, and a rigid cross-brace attached to the bleeder seat and holding the plug. Fluid flows around the check valve when open. The cross-brace positions the plug relative to the check valve through bore such that the plug seals against the check valve through bore when the check valve is closed.Type: GrantFiled: December 2, 2021Date of Patent: October 24, 2023Assignee: M. Carder Industries, Inc.Inventor: Randall Carder

Patent number: 11124409Abstract: An automatic shut-off fluid nozzle having a primary fluid path, a vacuum-actuated fluid shut-off assembly in the fluid path, said shut-off shutting off flow through the fluid path when the pressure chamber is subjected to a predetermined vacuum. The nozzle having a venturi port in said fluid path and connected to a vacuum channel, and a vacuum vent extending away from the vacuum channel, said vacuum vent communicating with a low vacuum environment. The nozzle further having a segregated fluid channel in the primary fluid path, the venturi port communicating with said segregated fluid channel, such that the flow of fluid past the venturi port creates a venturi vacuum in the vacuum channel. The vacuum exhausts the vacuum through the vent port when the vent port is in an open condition, and creates a vacuum in the vacuum-actuated fluid shut-off assembly when said vent port is in a closed condition.Type: GrantFiled: November 1, 2019Date of Patent: September 21, 2021Assignee: M.

Patent number: 7255142Abstract: A fuel nozzle guard, in some embodiments, comprises a static control material. When a consumer grabs the fuel nozzle, his or her hand will touch the static control material, thereby, safely dissipating any electrostatic charges at a controlled rate of discharge without a spark. The fuel nozzle guard, in some embodiments, slides onto the nozzle interfacing with the nozzle so that retaining edges secure the fuel nozzle guard to the nozzle, without removing the nozzle from its hose. The material, in some embodiments, lacks plastisol and allows labels to adhere directly to it.Type: GrantFiled: December 15, 2004Date of Patent: August 14, 2007Assignee: M. Carder Industries, Inc.Inventors: Mervin L. Carder, Sr., Mervin L. Carder, Jr., E. Leonard Poli

Patent number: 7255140Abstract: An automatic shut-off nozzle having an operating lever pivoted at its forward end to a plunger, a clip pivoted to the lever, the clip engaging a holding structure and holding the lever open when the plunger is elevated and the lever lifted, and at least one protrusion on the lever or the clip for mechanically forcing the clip out of engagement with the structure when the plunger drops.Type: GrantFiled: April 27, 2005Date of Patent: August 14, 2007Assignee: M. Carder Industries, Inc.Inventor: E. Leonard Poli

Patent number: 5141014Abstract: A breakaway coupling for joining two hoses includes a main body and an end body which are telescopically connected. A frangible link holds the two parts together. The link is inserted in a recess formed in a surface of the coupling which spans the junction of the bodies. The link is subject only to tensile forces and is formed to break at across the center of the link, where the two bodies abut each other. Each body includes a check valve. When the two bodies are connected, the valves urge against one another to open the valves. The urging of the valves against one another also exerts a tensile force on the link to hold it in its recess. A spacer separates the valves so that high pressure flow will not close the upstream valve.Type: GrantFiled: May 28, 1991Date of Patent: August 25, 1992Assignee: M. Carder Industries, Inc.Inventors: E. Leonard Poli, Mervin L. Carder

Patent number: 4487238Abstract: A fluid dispensing nozzle for gasoline or the like includes a valve seat, a poppet valve for controlling flow through the valve seat, a spring urging the poppet valve closed, a valve stem extending into the poppet valve, a handle engaging the valve stem for manually urging the poppet valve away from its seat and a high-level shut-off means for disabling the handle. The poppet valve assembly is constructed to lift one side of the poppet when the handle is initially lifted.Type: GrantFiled: September 9, 1982Date of Patent: December 11, 1984Assignee: M.
