Patent number: 5706985Abstract: A combination cap and handle for use with a detachable humidifier reservoir tank. Extending through the cap is a tubular aperture containing a biased plunger that interacts with a base pin in the water receiving portion of the humidifier. The plunger is attached to a flap such that when the reservoir tank is placed into the body of the humidifier, the plunger and flap are urged into the reservoir tank, allowing the water in the reservoir to fill the humidifier. Extending radially from the plunger aperture on the external surface of the cap are raised handles. These handles allow for a mechanical advantage when the user wishes to remove the cap from the reservoir, or to transport the reservoir more easily both when full and when empty.Type: GrantFiled: June 6, 1995Date of Patent: January 13, 1998Assignee: Holmes Products Corp.Inventor: David L.

Patent number: 5658130Abstract: A window mounted oscillating fan. The fan has two blower modules each having a motor, fan blade, and diffuser. The diffuser is fixed in a stationary position relative to its fan blade. The window fan oscillates by pivoting all blower modules simultaneously through a single motorized oscillation mechanism. The blower units may be arranged to discharge air in parallel, or alternatively, in different directions. The blower units pivot about an axis inclined from the vertical, so that oscillation has a vertical component as well as horizontal. In different embodiments, the fans operate in tandem, facing the same direction at all times, or oscillate in different directions, thereby diffusing incoming air. The window fan has an air filter, and manual and automatic controls including a touch sensitive on-off switch, a thermostatic on-off switch, and a speed selector.Type: GrantFiled: December 15, 1995Date of Patent: August 19, 1997Assignee: Holmes Products Corp.Inventors: Andrew Goldstein, David Feer, Robert Barker

Patent number: 5655055Abstract: A portable forced air space heater having a three hundred sixty degree peripheral dispersion pattern. The heater has a tubular housing and a fan forcing air past a heating element upwardly within the housing. The air encounters a conical deflector which redirects the air to flow outwardly at the top of the housing. One or more movable baffles are selectively placed in the housing so as to obstruct discharge of air at various selected sections of the peripheral pattern of discharge. This feature prevents injurious or otherwise objectionable discharge of heat when the heater is placed close to another object. The baffles are arcuate, so that they cooperate with the tubular housing, and insulated to minimize propogation of heat to the obstructed portion of the discharge pattern. Baffles are removable from the heater, and are maneuvered for adjusting their position from outside the heater.Type: GrantFiled: October 13, 1995Date of Patent: August 5, 1997Assignee: Holmes Products Corp.Inventors: Andrew Goldstein, Lawrence M.
