International Classification:

B01D 46/00

US Classification:

55529, 55498, 55DIG 28, 123 4165, 123198 E, 292 15, 292253, 2923366, 292359, 411 81, 411352, 411353, 411427, 411435, 411970

Abstract:

The invention has a captive tooless fastener for securing the engine intake air filter. The tooless fastener comprises shaft and associated bodies. The body has two arms oriented about 180 degrees apart. The shaft is threaded through a sealing washer and an aperture in a closed end cap of the air filter. The shaft is expanded so it cannot be removed from the end cap. The body's threaded inner diameter mates with a threaded portion of a central shaft in an air filter housing. The body's arms are rotated to screw the fastener and the shaft of the housing together. When tightened, the sealing washer closes the aperture. To remove the air filter, the fastener is unscrewed from the shaft of the housing and in the shaft floats in the aperture. A person in the field can remove the air filter by inserting fingers under the arms and pulling.

Appl. No.:

13/433029

Inventors:

Kenneth S. Schultz - Evanston IL, US
William F. Crowe - Harvard IL, US
Roy E. Greenlees - Lake Forest IL, US

International Classification:

E04H 4/16

US Classification:

21016719

Abstract:

A removable skimmer net assembly that securely sits within the mouth of any conventional pool skimmer to passively collect floating debris from the surface of the water. The skimmer net assembly includes a removable pool net and a skimmer mount having a telescoping column and a T-shaped net orientation connector. The telescoping column secures the mount within the mouth of the pool skimmer in either a vertical or horizontal orientation. The net orientation connector allows the removable net to be properly positioned within the pool regardless of the orientation of the telescoping column or the style of skimmer. The removable pool net is connected to the skimmer mount by a dove-tail joint that allows the net to be easily disconnected from the mount for cleaning or when the pool is in use.

Assignee:

United Air Filter, Inc. - Cicero IL

International Classification:

F02B 7700

US Classification:

553851

Abstract:

An engine filter assembly for cleaning cooling air for an internal-combustion engine for use in high-debris environment such as in roofing-removing machines includes a protective element housing attached to the machine at a remote position. The protective element housing houses a two-stage air filter having a cylindrical-shaped filter element with an outer pre-filter covering. An air inlet housing on the engine is connected to the protective element housing by a flexible coupling link. A shield protects the engine from direct contact with loose or air-born materials during the operation of the machine. A thermal sensing device reads the temperature of the engine and automatically shuts down the engine if the temperature elevates beyond specification, reducing the chance of engine failure.

Abstract:

An engine filter assembly for cleaning cooling air for an internal-combustion engine for use in high-debris environment such as in roofing-removing machines includes a filter housing attached to the machine at a remote position. The filter housing houses a two-stage air filter that consists of a cylindrical-shaped filter element with an outer pre-filter covering. Both the carburetor air inlet and a fan housing leading to the cooling fan on the engine are connected to the filter housing by tubing. A shield protects the engine from direct contact with loose or air-borne materials during the operation of the machine. A thermal sensing device reads the temperature of the engine and automatically shuts down the engine if the temperature rises beyond specification, reducing the chance of engine failure.
