Patent number: 8060978Abstract: A road sweeper includes a blower housing having an opening, a hopper having an opening, and the openings being in axial alignment when the hopper and blower housing are each in a sweeping position thereof. The blower housing is biased for tilting movement from its sweeping position to an inclined dump position upon relative movement of the hopper to preclude abrasion, wear and damage to an O-ring seal disposed between the openings. The blower housing can also be moved to a third repair position in which components thereof are accessible from the cab side of the sweeper.Type: GrantFiled: August 8, 2005Date of Patent: November 22, 2011Assignee: TYMCO, Inc.Inventors: Gary B. Young, James C. Crow

Patent number: 7488042Abstract: A dump hopper for a road sweeper includes a dump door, a debris guide chute, and an actuating mechanism for pivoting the dump door and debris chute between travel and dumping positions. The dump door is sandwiched between a hopper and the guide chute in the travel position and seals a debris discharge opening of the hopper. A pair of fluid cylinders are pivotally connected to the dump door and the guide chute and cooperate with cam and cam followers to hold the dump door in sealed relationship to the debris discharge opening until the debris guide chute has been fully deployed.Type: GrantFiled: January 18, 2007Date of Patent: February 10, 2009Assignee: Tymco Inc.Inventor: Gary B.

Patent number: 6161250Abstract: A closed-loop Regenerative.RTM. air sweeper is provided which constitutes an improvement of that disclosed in U.S. Pat. No. 3,512,206. The sweeper of the latter patent is provided as an integral portion thereof, whereas a conversion, a "dustless" mechanism having first and second chambers into the first chamber of which is directed a portion of the air stream from a pressure conduit associated with a pickup head of the sweeper. Particles of debris are separated by cyclone separators and thereafter by membrane filters after which substantially clean air is discharged to atmosphere. Air entrained particles separated by the cyclone separators and the cartridge filters are returned to a vacuum side of the pickup head thereby maintaining substantially closed-loop air flow of the sweeper. Clean air is controllably exhausted to atmosphere by flue vanes which can be selectively moved under pressure differential sensing means associated with the cyclone separator.Type: GrantFiled: August 16, 1999Date of Patent: December 19, 2000Assignee: Tymco, Inc.Inventors: Gary B. Young, Joseph Dvorsky

Patent number: 5564147Abstract: A pick-up head is formed by a housing which defines a broom chamber rearward of an associated air pressure chamber and its associated blast orifice. The broom is rotated in a direction to impel debris from a surface in the same direction as air emitted from the blast orifice toward an associated air suction chamber. Due to the latter arrangement, debris which is "tacky" which is "stuck" onto the surface, or which is too heavy to be moved into the suction air stream by the blast air alone is impelled at a relatively high entrainment velocity toward and into the air suction stream which continues the movement of this debris for eventual discharge into an associated hopper.Type: GrantFiled: June 7, 1995Date of Patent: October 15, 1996Assignee: Tymco, Inc.Inventor: Gary B. Young

Patent number: 5188577Abstract: An exercising apparatus for full body exercise has a base member adapted to rest upon a floor and a support frame extending upwardly therefrom. The support frame has a pair of foot pedals pivotally attached thereto about midway of each foot pedal. A cross member attached to the upper end of the support frame has a pair of independently articulated pivotal arm handles rotatably attached to the cross-member. A pair of adjustable compressed spring tension devices are attached between each foot pedal and the upper cross member. A pair of actuating rods are pivotally attached respectively between each foot pedal and each arm handle, so that movement of either the arm handle or the foot pedal actuates the other member. Each of the two foot pedal-arm handle combinations is independently actuated, and not dependent on the other for movement.Type: GrantFiled: July 13, 1992Date of Patent: February 23, 1993Inventors: Gary B. Young, Jack N. Young, Steven R. Young, Franklin E. Young

Patent number: 4773121Abstract: A high-speed pick-up head includes an air pressure chamber and an air suction chamber respectively associated with an elongated blast orifice and a suction orifice. The chambers are arranged in side-by-side relationship generally normal to the direction of vehicle/pick-up head travel and have opposite first and second ends. Each chamber defines an elongated volume corresponding in length generally to the orifice associated therewith with each volume decreasing in cross-sectional area toward its closed end. Respective air inlets and air outlets of the pressure and suction chambers are opposite each other and the blast orifice can be changed in size and/or shape, preferably diverging in a direction away from the pressure chamber air inlet to maintain maximum air velocity/flow which blasts or blows sand or similar dense debris from airport runways for subsequent removal/separation at extremely high efficiencies.Type: GrantFiled: February 27, 1987Date of Patent: September 27, 1988Assignee: TYMCO, Inc.Inventor: Gary B.
