Publication number: 20150202666Abstract: An apparatus for propelling a plurality of coil clad hoses simultaneously includes a plurality of modules. Each module includes a primary driven bull gear. A follower bull gear is rotatably fastened to a follower axle extending parallel to the drive axle and the follower bull gear meshes with the primary bull gear. A plurality of secondary bull gear/sprocket modules are fastened to each of the axles, each of the modules having a secondary bull gear having teeth extending to a first outer diameter and a sprocket gear having teeth extending a distance less than the first outer diameter. The secondary bull gear teeth of modules on the drive axle mesh with corresponding secondary bull gear teeth of modules on the follower axle to define between adjacent modules an opening width for receiving and passing therebetween a coil clad portion of a high pressure hose.Type: ApplicationFiled: March 27, 2015Publication date: July 23, 2015Inventor: Gerald P. Zink

Patent number: 9022057Abstract: A flow path switching valve is disclosed that can be operated remotely simply by turning flow on and off. A mid portion of the body has at least one passage therein leading from a central axial bore to one or more external ports each having a tractor nozzle. The valve outlet connects the axial bore to a cleaning nozzle. A poppet member is received in the central axial bore. In a first position, the poppet member directs fluid flow through the outlet to the cleaning nozzle connected to the outlet. The poppet member, when in a second position, closes the central axial bore through the outlet end of the valve body and permits fluid flow through the tractor nozzles. Selection of the different flow paths is made by simply reducing flow through the valve below a predetermined fluid flow threshold and then increasing the flow rate above the threshold.Type: GrantFiled: February 11, 2014Date of Patent: May 5, 2015Assignee: Stoneage, Inc.Inventor: Gerald P. Zink

Patent number: 9016613Abstract: A system for storing, rotating and feeding a high pressure hose. A first portion of the hose is disposable about the drum and a guide arm engages a second portion of the hose. An actuator assembly rotates a cage and the guide arm so that the guide arm rotates relative to the cage such that the hose is rotated. Relative rotation in one direction causes the first portion of the hose to uncoil from the drum and displace along the guide arm and causes a third portion of the high pressure hose in an output port to displace out of the output port away from the guide arm. Relative rotation in an opposite direction causes the second portion of the high pressure hose to coil about the drum and causes the third portion of the high pressure hose to displace into the housing.Type: GrantFiled: July 18, 2013Date of Patent: April 28, 2015Assignee: Stoneage, Inc.Inventor: Gerald P. Zink

Publication number: 20150000760Abstract: An apparatus for insertion in an enclosed space, including: a tube with: first and second substantially straight portions including first and second ends of the tube, respectively; and a curved portion connecting the first and second portions. The apparatus includes: a plurality of nested segments at least partially disposed within the first substantially straight portion of the tube and connected to the first substantially straight portion; and a first actuator engageable with the tube to displace the first and second substantially straight portions of the tube into and out of the enclosed space through an opening into the enclosed space. The tube is arranged to accept a hose passing through the tube, and a distal segment from the plurality of nested segments is connectable to the hose.Type: ApplicationFiled: September 12, 2014Publication date: January 1, 2015Inventor: Gerald P. Zink

Publication number: 20140352464Abstract: An apparatus is disclosed for propelling a coil clad hose through a passage through a housing. A first driven pair of bull gears sandwiching a rotatable drive sprocket is rotatably fixed to a first rotatable axle in the housing orthogonal to the passage. A second pair of bull gears sandwiching a second drive sprocket are all rotatably fastened to a second axle in the housing parallel to the first axle. The second pair of bull gears mesh with the first pair of spaced bull gears. Teeth on the drive sprockets engage part of the coil clad hose when the fluid hose is inserted into the passage. A slip clutch between the pairs of spaced bull gears and the drive sprocket on each of the axles adjusts frictional grip on the coil when one of the bull gears is driven to propel the hose through the passage.Type: ApplicationFiled: May 30, 2013Publication date: December 4, 2014Applicant: STONEAGE, INC.Inventor: Gerald P.

Patent number: 8887343Abstract: A system and method for propelling a hose, including: a system housing and a tractor element disposed in the housing. The tractor element includes: a tractor housing with a through-bore; and a protrusion extending into the through-bore. The system includes: a hose assembly including a substantially helical coil disposed about a hose; and an actuator for rotating the tractor housing with respect to the system housing. The tractor element is fixed in the system housing with respect to axial movement; and the hose assembly can be disposed in the through-bore so that the protrusion contacts a portion of the coil. As the tractor housing is rotated in a rotational direction: the protrusion exerts a displacement force on the coil; and the hose assembly reacts to the displacement force by displacing in an axial direction.Type: GrantFiled: March 12, 2010Date of Patent: November 18, 2014Assignee: Stoneage, Inc.Inventor: Gerald P.

Patent number: 8863775Abstract: A flow path switching valve is disclosed that can be operated remotely simply by turning flow on and off. The switching valve may be incorporated into the body of a high pressure nozzle. In one embodiment a mid portion of the valve body has at least one passage therein leading from a central axial bore to first and second external ports. A poppet member received in the central axial bore directs fluid flow in a first position to the first external ports. The poppet member, when in a second position, closes the central axial bore through the outlet end of the valve body and permits fluid flow through the second set of external ports. Selection of the different flow paths is made by simply reducing flow through the valve below a predetermined fluid flow threshold and then increasing the flow rate above the threshold.Type: GrantFiled: February 6, 2012Date of Patent: October 21, 2014Assignee: Stonage, Inc.Inventors: Gerald P. Zink, Neil C. O'Connor

Publication number: 20140151488Abstract: An apparatus for storing, rotating and feeding a high pressure hose, including: a first rotatable drum with a helical groove; a second rotatable drum; and at least one actuator for rotating the first and second drums. For rotation of the first and second drums in first and second opposite directions, respectively, a hose and a cable are coilable into the helical groove such that the hose is in compressive engagement with the cable and the first drum. For rotation of the first and second drums in the second and first directions, respectively, the hose is uncoilable from the first drum and displaceable beyond the apparatus and the cable is coilable about the second drum.Type: ApplicationFiled: February 5, 2014Publication date: June 5, 2014Applicant: STONEAGE, INC.Inventor: Gerald P.
