Patent number: 11915259Abstract: A computerized system for transacting the purchase and sale of consumer motor fuels between motor fuel merchants and retail consumers through software on a mobile or desktop connected device for periods in the future through the simultaneous execution of multi-party, multi-layered contingent transactions and pricing algorithms to ensure that all inter-related motor fuel merchant transactions are simultaneously transacted upon a retail consumer purchase execution. Motor fuels include refined products such as gasoline and diesel fuel, renewable fuels (e.g. ethanol, biodiesel), natural gas (including liquefied natural gas), jet fuel and electricity.Type: GrantFiled: September 2, 2021Date of Patent: February 27, 2024Assignee: Gasmart, LLCInventors: Joseph H.

Patent number: 5386753Abstract: Cross cuts for forming the ends of a tab on a sheet, for example a glue tab on a corrugated paperboard container blank, are performed by independent rotary cutter units. Each cutter unit has a spirally convoluted blade which, as it rotates, cuts progressively inwards from an outside edge of the sheet towards an opposite outside edge. As the sheet is conveyed along, a downstream cutter unit cuts the leading end of the tab, and an upstream cutter unit cuts the trailing end. After each cut, the cutter remains at rest with its blade in an inoperative position out of the path of any oncoming sheet. A sensor senses the next oncoming sheet and initiates the cutting via a computer. These rotary cutters mitigate skewing of the sheets while being cut.Type: GrantFiled: May 14, 1993Date of Patent: February 7, 1995Assignee: Ward Holding Company, Inc.Inventors: Michael P. Baron, John R. Harrison, William F. Ward, Jr.

Patent number: 4958829Abstract: Apparatus, for example for processing sheets of corrugated paperboard in the production of container blanks, has a pair of feed rolls between which the sheets are fed while passing through the apparatus, and a pair of side frames in which the feed rolls are rotatably mounted one above the other. The upper of the feed rolls is journalled in bearings mounted eccentrically in bearing housings rotatable in holes in the side frames. Gearing is provided for adjustably rotating the bearing housings in the holes to move the upper feed roll respectively away from and towards the lower of the feed rolls. A pair of wedges act upon each bearing housing and are disposed in a cavity in each side frame below and communicating with the respective bearing housing. The wedges are moved towards each other by a screw bolt and/or a fluid cylinder to pre-load the bearing housings upwards in their holes.Type: GrantFiled: February 1, 1989Date of Patent: September 25, 1990Assignee: The Ward Machinery CompanyInventor: William F. Ward, Jr.

Patent number: 4878407Abstract: A method and apparatus for mounting a die, particularly a rigid cutting die, on a die cylinder includes having a bubble along a seal on the die to bridge any gaps between the die and the die cylinder when the die is initially positioned on the die cylinder. This bubble seal enables a vacuum to be applied between the initially positioned die and the die cylinder to pull the die down against and into conformity with the surface of the die cylinder, at the same time flattening the bubble seal. A key at a trailing edge of the die locates in an axial keyway in the die cylinder to circumferentially position the die; a bolt is then inserted at a leading edge of the die to establish axial location. During operation the die is held in position by the vacuum. Beam sensors and light reflectors may be incorporated to sense when a wrong die is present and shut down the apparatus.Type: GrantFiled: May 17, 1988Date of Patent: November 7, 1989Assignee: The Ward Machinery CompanyInventors: John R. Harrison, Gary L. Lehr, Dennis J. Parr, William F. Ward, Jr., Robert R. Wells

Patent number: 4643413Abstract: A sheet feeder for corrugated paperboard sheets utilizing timed intermittently rotatable belts against which either the top or bottom sheet, depending on the configuration chosen, of a stack is brought into contact to feed such sheet in synchronism with adjacent processing machinery and utilizing continuously applied negative atmospheric pressure to hold such sheet against the belts without the need for valving or otherwise breaking the suction pressure.Type: GrantFiled: March 7, 1984Date of Patent: February 17, 1987Assignee: The Ward Machinery CompanyInventors: William F. Ward, Sr., John B. West

Patent number: 4596541Abstract: A method of slitting selected plies of multiply paperboard blanks by compressing narrow portions against an anvil surface (preferably soft) and cutting one or more plies along the compressed portions. The apparatus includes a cutting rule (straight or annular) with compression rules on each side to compress the blanks simultaneously with the cutting. The method and apparatus may be used in conjunction with conventional flat-bed or rotary diecutting.Type: GrantFiled: September 9, 1983Date of Patent: June 24, 1986Assignee: The Ward Machinery CompanyInventors: William F. Ward, Sr., Raymond S. Watson

Patent number: 4516628Abstract: An air heater for recovering energy from process exhaust gases and the like includes a heat exchanger disposed in the flow of exhaust gases, a blower for supplying an independent flow of air to be heated in the exchanger and the control system including dampers, driving mechanisms and thermostats for adjusting air flow in order to maintain substantially constant heated output air temperature. One of the dampers is disposed at the outlet of the blower and adjusts, by a thermostat an appropriate drive mechanism, the volume of air supplied by the blower based on outlet temperature. A pair of dampers are connected in oppositely acting (face and bypass) fashion and adjust the proportion of air passing through or bypassing the heat exchanger, again based on the temperature of the outlet air as sensed by a thermostat.Type: GrantFiled: September 30, 1982Date of Patent: May 14, 1985Inventor: William F. Ward

Patent number: 4500244Abstract: Apparatus for directing a flow of air between the bottom blank of a stack and a blank advancing beneath the stack, particularly for corrugated paperboard counter stacker machines, comprising an air supply means adjacent the trailing edge of the bottom blank adapted to direct the flow of air beneath the bottom blank and above the advancing blank to form a cushion of air therebetween for reducing sliding friction between such blanks.Type: GrantFiled: December 20, 1982Date of Patent: February 19, 1985Assignee: The Ward Machinery CompanyInventors: Louis M. Sardella, William F. Ward, Sr.

Patent number: 4474565Abstract: Improved blank-stripping apparatus for rotary die cutters of the type which have a die cutting roll, and an anvil roll for supporting paperboard blanks against a cutting rule on the die cutting roll, includes a rotary-cam-timed valve system pressure-actuating one or more pneumatic piston and cylinder assemblies within or adjacent the cutting rule for ejecting scrap radially from the cutting rule in synchronism with rotation of the die cutting roll; after scrap ejection the valve system vents pressure so that contact with a succeeding paperboard blank and/or spring bias easily retracts the plunger to position for pneumatic actuation in the succeeding cycle of operation.Type: GrantFiled: February 25, 1982Date of Patent: October 2, 1984Assignee: The Ward Machinery CompanyInventors: Raymond S. Watson, William F. Ward, Sr.

Patent number: 4280386Abstract: Rotary slitting apparatus for slitting paperboard material including a pair of coacting knife holders for mounting on parallel adjacent rotatable shafts, such holders having thin flexible annular slitting blades clamped thereon at a slight angle to a plane normal to the axis of the shafts so that the blades overlap slightly to provide scissors-action cutting of paperboard material passed between the heads.Type: GrantFiled: December 26, 1979Date of Patent: July 28, 1981Assignee: The Ward Machinery CompanyInventor: William F. Ward, Sr.

Patent number: 4240312Abstract: A method and apparatus for extending the useful life of resilient covers on anvil rolls of rotary die cutters by causing the die cutting rules to penetrate the covers at sequential incrementally small circumferentially spaced locations around the cover by adding to the speed of rotation of the anvil roll relative to the speed of the die holder roll. Lateral reciprocation of the anvil roll is translated to rotary motion by a gear and pivot lever arrangement, such rotary motion being added to the normal speed of the anvil roll.Type: GrantFiled: May 15, 1979Date of Patent: December 23, 1980Assignee: The Ward Machinery CompanyInventor: William F. Ward, Sr.
