US Patent:

41035224, Aug 1, 1978

Filed:

Mar 25, 1977

Appl. No.:

5/781501

Inventors:

George M. Gibson - Riverdale NY

International Classification:

D06F 1710

US Classification:

68133

Abstract:

A spiral outwardly facing surface, driving surface, of a dasher forces wash almost radially outwardly with little tendency for the wash to be whirled with the dasher. Therefore, the dasher can be driven unidirectionally by apparatus that is much simpler and more economical than the gearing used for reciprocating motion in conventional washing machines. Preferably, the height of the spiral surface is low, the change in rate of curvature is gradual, and a line normal to the tangent of the outer portion of the spiral is nearly radial to propel clothes radially while the dasher is being rotated at a speed within the range of speed normally used for drying by spinning. The use of the spinning rate further simplifies the rotative driving apparatus.

International Classification:

D06F 1710

US Classification:

68133

Abstract:

A spiral gyrator to be driven unidirectionally at a rate within the normal range for drying by spinning has a spiral strip about a base and upwardly on a central, upright post. The direction of the spiral is reversed for a turn near the top of the post. The first part of the spiral strip farthest from the center on the base has a plurality of spaced slots through it for creating radial jets of washing fluid to move wash rapidly in a pulsating manner. The rotative driving apparatus for the gyrator is simplified, and the reverse turn of the spiral strip near the top of the post prevents wash from being forced over the top of the post while the rotation of the gyrator is reversed and the tub of the washing machine is accelerating to a spinning rate.

International Classification:

B66B 100

US Classification:

187 49

Abstract:

Between floors or landings the elevator car door may be opened allowing passengers to open the hall door. To prevent this from occurring, a stop apparatus is attached to the car door and hall door. This apparatus allows the car door to only be opened to a certain minimum acceptable distance when the car is above a predetermined distance above the landing.
