20110163185 | Quick Needle Pullback Mechanism To Clean The Needle Valves In Air Brushes - An air brush is provided with the quick needle pullback mechanism thereby allowing the user to apply quick flushes. This is composed of first pushing down on the trigger to open the air valve and then retracting the needle fully and allowing the needle to be pushed forward by the spring, effectively using the pressured air and paint to clean the nozzle. The distance of the pullback is regulated by a pre-set adjustment knob. A needle chuck and a needle lock perform the function of affixing to the needle, which regulates the paint or media flow. Under normal use, the pre-set adjustment knob defines the maximum paint output by stopping the needle from traveling backward farther than the preset position. When the user wishes to clean the nozzle, the pre-set adjustment knob may be dialed sufficiently back to allow the needle to be fully retracted by the quick pullback mechanism, thereby causing the nozzle to open up fully, allowing the extra paint to rush through the nozzle, and thereby cleaning the nozzle head area. | 07-07-2011 |
20120267416 | Safety Catch Mechanism for Nail Gun - A safety catch mechanism, comprising a safety catch that is captively attached to the barrel of a nail gun by matching tracks on both said safety catch and said barrel, facing each other, so that said safety catch is allowed to move only in the forward and backward directions along the barrel of the nail gun in the direction of the motion of the nails, is disclosed. A forward pushing means keeps the forward end of the safety catch beyond the muzzle of the nail gun in the initial secured position. As the safety catch is pushed back, the trigger of the nail gun is activated. | 10-25-2012 |
20130219666 | PLIANT REMOVEABLE AIRBRUSH GRIP - A grip for a handheld airbrush is described. The grip comprises pliant material piece having a first cylindrical passage that includes an open axial seam and a second cylindrical passage that is closed, where the second substantially cylindrical passage intersects the first substantially cylindrical open passage opposite the open axial seam. The pliant material piece fills area between ends of the first substantially cylindrical passage and of the second substantially cylindrical passage. The grip is installed with the second substantially cylindrical passage over the airbrush handle or stem and the first cylindrical passage around the cylindrical body with the airbrush toggle extending through the open axial seam. Depressed regions on opposite sides of the pliant material piece aid a user's grip. The grip may be employed with a secondary toggle grip for a toggle button of the airbrush. | 08-29-2013 |
20160059398 | VACUUM PISTON RETENTION FOR A COMBUSTION DRIVEN FASTENER HAND TOOL - A combustion driven fastener hand tool is disclosed having a piston driven by combustion within a chamber, the piston affixed to a driver for forcing a fastener. The piston forms a retention chamber having a lower internal pressure (“vacuum”) than that of the surrounding combustion chamber when the piston is disposed in the starting position for operation of the device. The lower internal pressure of the retention chamber (generated from a previous combustion cycle) momentarily holds the piston in place such that combustion behind the piston must first increase sufficiently to overcome holding force of the retention chamber before the piston moves. Requiring build up of combustion chamber pressure before piston motion greatly improves efficiency and power of the device. Use of the vacuum retention chamber is readily tunable with proper sizing of the chamber. | 03-03-2016 |
20160059399 | COMBUSTION DRIVEN FASTENER HAND TOOL - A combustion driven fastener hand tool is disclosed having an extruded front body component including two to three parallel bores. A first bore forms a cylinder for the piston which drives the fastener. A second bore forms a primary combustion chamber in which a fuel and air mixture is ignited and directed into the adjacent piston cylinder. A third bore (or alternately an attached component) forms a pathway for the fuel and air mixture to be directed into the primary combustion chamber. The combustion driven fastener hand tool includes numerous other features affording improvements over the prior art. | 03-03-2016 |
