Patent number: 8757574Abstract: A hose reel (10) is supported by a mounting bracket (12) which can be attached on a vertical or horizontal surface and allow for 180 degrees of motion to allow the hose reel (10) to automatically swivel in the direction the hose (14) is being pulled. The bracket mechanism (16) consists of integral mounting bosses (18) on the hose reel enclosures (20), a mounting bracket (12), a tube (22) and a constraint device (24) on the tube (22). The mounting bosses (18) on the hose reel enclosures (20) are designed to orient and constrain the mounting tube (22) to allow for the tube to be installed from either end of the hose reel. The constraining device (24) on the tube (22) locks into an integral opening (26) in the mounting bosses (18) to prevent tube (22) displacement in either direction.Type: GrantFiled: October 27, 2010Date of Patent: June 24, 2014Assignee: Graco Minnesota Inc.Inventors: Mark L. Bauck, Zaixing You, Lihui Gao, Xueshui Wu, Jin Tian

Patent number: 8568112Abstract: An air valving system for a reciprocating piston pump (5) which uses piston (10) actuated poppet assemblies (40) to control the main air valve (16) shift. The valve exhaust is vented (50) directly to atmosphere rather than through the main exhaust to ensure reliability. A ramped detent (32) prevents the air valve (16) from centering.Type: GrantFiled: July 26, 2006Date of Patent: October 29, 2013Assignee: Graco Minnesota Inc.Inventors: Mark L. Bauck, John F. Isais, Jr., Mark T. Weinberger, David M. Pittman, Michael E. Bloom

Patent number: 8312785Abstract: An oval gear set for use in a flow meter comprises first and second gears that are identical to each other and that are configured to engage at a fixed center-to-center distance such that the first and second gears mesh at all angular positions. Each gear of the oval gear set comprises a hub and a plurality of gear teeth. The hub comprises an oval body having a major axis and a minor axis extending through a center of the hub, and a root profile wall circumscribing the major and minor axes. The plurality of gear teeth extend from the root profile wall. Each of the gear teeth has a pair of contact surfaces with circular involute curve profiles.Type: GrantFiled: June 20, 2008Date of Patent: November 20, 2012Assignee: Graco Minnesota Inc.Inventors: David L. Breeser, Mark L. Bauck, John C. Holman

Patent number: 8215522Abstract: A hand-held flow metering device for dispensing a pressurized fluid comprises a valve, a flow meter, a trigger lever, a trigger release mechanism and meter electronics. The valve is connected to the pressurized fluid to regulate flow of the pressurized fluid through the device. The flow meter is disposed within the flow of pressurized fluid to measure volumetric flow of the pressurized fluid. The trigger lever is configured to be manually displaced to mechanically open the valve. The trigger release mechanism is connected to the trigger lever and is selectively actuated to mechanically prevent the trigger lever from opening the valve when the trigger lever is displaced. The meter electronics is connected to the flow meter and the trigger release mechanism to actuate the trigger release mechanism based on output of the flow meter.Type: GrantFiled: June 20, 2008Date of Patent: July 10, 2012Assignee: Graco Minnesota Inc.Inventors: David L. Breeser, Mark L. Bauck, John C. Holman

Publication number: 20120168549Abstract: An enclosed hose reel 10 consists of a spool and two enclosure halves 14 comprising the frame 16. The power spring 18 is contained in the spool 12. Tension on the power spring 18 is transmitted to the frame 16 via a shaft 20 with a spring 30 loaded ratchet 22. The ratchet mechanism 24 engages the frame 16 via protrusions 26 that fit into cutouts 28 within the enclosure 14. The protrusions and cutouts 28 are designed so that a clockwise rotation is allowed to increase the tension of the power spring 18.Type: ApplicationFiled: October 27, 2010Publication date: July 5, 2012Inventors: Mark L.

Publication number: 20090288403Abstract: The induction exhaust has an exhaust manifold 16 and a muffler 22. In the instant invention, warm ambient air is drawn into the muffler 22. Heat from this external source is conducted through the finned manifold 16 to melt ice that can form inside the manifold 16 during the exhaust cycle. The exhaust manifold 16 bolts to the side of the air motor air valve 14 and serves to direct, muffle and diffuse the air motor exhaust using a deflection plate, a diffraction plate and an expansion chamber is provided in the manifold to direct the exhaust out of the air valve and down the center of the muffler 22.Type: ApplicationFiled: July 25, 2007Publication date: November 26, 2009Inventors: David M.
