Patent number: 11919758Abstract: A double action hydraulic jack has a primary hydraulic pump in fluidic communication with the hydraulic fluid reservoir and with the lift cylinder. The hydraulic jack has an auxiliary hydraulic pump also in fluidic communication with the hydraulic fluid reservoir and the lift cylinder. The auxiliary hydraulic pump operates at light-load conditions to drive the jack ram upwards at a rate at least three times faster than at heavy lift-load conditions with only the primary hydraulic pump in operation.Type: GrantFiled: May 25, 2022Date of Patent: March 5, 2024Assignee: Gaither Tool Company, Inc.Inventor: Daniel Kunau

Publication number: 20210364091Abstract: A pneumatically operated gas valve mounted on a vessel containing pressurized gas. The gas valve includes a piston positioned in a cylinder with one closed end so that the piston seats against a gas outlet to close the gas valve. A control reservoir is formed in the cylinder between the piston and the closed end of the cylinder. Upon filling vessel, some of the pressurized gas enters the control reservoir to provide a control pressure behind the piston. Actuating the control mechanism vents the control reservoir, resulting in the gas valve opening rapidly to release the pressurized gas in the vessel through an exhaust port of the gas valve.Type: ApplicationFiled: August 3, 2021Publication date: November 25, 2021Applicant: Gaither Tool Company, Inc.Inventor: Daniel Kunau

Patent number: 10800215Abstract: A nozzle for seating a tubeless tire on a rim using pressurized gas includes a coupling neck configured to accept the pressurized gas from a pressurized tank, a choke point adapter connected to the coupling neck and a nozzle body configured with a nozzle output. Pressurized air introduced into the coupling neck pass through the nozzle and exits the nozzle output in a burst of the pressurized gas that is directed between the tubeless tire and the rim to inflate the tire. The choke point adapter has a chokepoint surface with a chokepoint angle of sufficient angle to aid in reducing the recoil of the tubeless tire seating device.Type: GrantFiled: October 13, 2015Date of Patent: October 13, 2020Inventor: Daniel Kunau

Patent number: 10800216Abstract: A tool for seating a tubeless tire on a rim using pressurized gas includes a cylindrical pressure tank with a nozzle affixed to it, and a rapid opening gas valve. The nozzle includes a jet configured to receive pressurized gas from the cylindrical pressure vessel into a chamber of the nozzle. As the stream of gas enters the chamber, the Venturi effect causes air to enter the chamber through air intake ports and the stream of gas and air from the air intake ports is blown out of the outlet of the nozzle. The tire is seated on the rim by positioning the system so that the air from the nozzle rapidly blows into the tire between the bead of the tire and the rim upon the valve being opened.Type: GrantFiled: May 16, 2017Date of Patent: October 13, 2020Assignee: Gaither Tool Company, Inc.Inventor: Daniel Kunau

Publication number: 20170002910Abstract: Methods and systems are provided for making and using a differential locking gear for locking a differential gear assembly that a first side gear connected to a first axel and a second side gear connected to a second axel. The differential locking gear has a first side with teeth configured to simultaneously mesh with first side gear teeth of the first side gear. The differential locking gear also has a second side with teeth configured to simultaneously mesh with second side gear teeth of the second side gear. The teeth of the differential locking gear that simultaneously mesh with the first and second side gears causes the first and second side gears to rotate in unison, thus locking the differential gear assembly.Type: ApplicationFiled: September 22, 2015Publication date: January 5, 2017Inventor: Daniel Kunau

Patent number: 9423196Abstract: A projectile launching device includes a barrel with a bore through the barrel, and a breach end opposite of a muzzle end. A feed mechanism, with a chamber to hold a projectile, is positioned at the breach end of the barrel. The feed mechanism is moveable between a first position with the chamber and the barrel unaligned, and a second position with the chamber and the barrel aligned. A receiver is positioned on an opposite side of the feed mechanism from the barrel. The receiver includes a gas duct to convey gas into the chamber to fire the projectile. A sleeve is slidingly coupled to the receiver and is adapted to forcibly slide into a position in contact with the feed mechanism, in response to pressure from the gas conveyed through the gas duct, to seal a first gap between the receiver and the feed mechanism.Type: GrantFiled: November 11, 2015Date of Patent: August 23, 2016Inventor: Daniel Kunau

Patent number: 9212860Abstract: An improve firearm rifling is provided in which the trailing edge face of the land is significantly longer than the rifling land top surface. The trailing edge angle between the trailing edge face and the level of the groove floor surface is a much smaller angle than conventional rifling land trailing edge angle, while the leading edge angle of the disclosed embodiments may be akin to a conventional rifling leading edge angle. Due to this, the present embodiments provide a rifling land profile that is nonsymmetrical, with the trailing edge face being at a much lower angle than the leading edge face which is configured in a more upright orientation.Type: GrantFiled: February 28, 2014Date of Patent: December 15, 2015Inventor: Daniel Kunau
