US Patent:

41250621, Nov 14, 1978

Filed:

Jul 22, 1977

Appl. No.:

5/817987

Inventors:

Marion L. Eakes - Greensboro NC

Assignee:

M. L. Eakes Co. - Greensboro NC

International Classification:

F23J 1100

US Classification:

98115LH

Abstract:

Contaminated exhaust gases being generated at a work table or work station having one or more open sides adjacent the area above the work table, and normally tending to rise into the atmosphere surrounding the work station, are collected in an exhaust hood which includes an inlet extending parallel to and generally above each of the open sides. A first portion of such exhaust gases collected are passed on to be filtered in conventional pollution abatement equipment; however, a second portion of the contaminated exhaust gases are rerouted, in some cases mixed with fresh outside air, and introduced through an air nozzle directed at the aforementioned inlet to the exhaust hood to improve the exhaust gas collecting, as well as reducing the requisite capacity of the filtration equipment and reducing the intake of make up air from the room surrounding the work table.

Filed:

Appl. No.:

5/943791

Inventors:

Marion L. Eakes - Greensboro NC

International Classification:

F21C 1508
F23J 1100

US Classification:

98115LH

Abstract:

Gases such as contaminated exhaust or stale air are induced toward a suction orifice by means of an air nozzle spaced from the orifice and pointing generally in the direction thereof to generate a Venturi effect on the gases at considerable distances from the suction orifice. An auxiliary plate extending generally parallel to and spaced slightly from the exposed wall of the air nozzle has one edge thereof positioned at a point farther away from the suction orifice than the outlet of the air nozzle, so that a secondary Venturi is generated and the capture point of the gases being collected is effectively moved further away from the suction orifice thereby improving the collection effect of the orifice.

Appl. No.:

5/645997

Inventors:

Marion L. Eakes - Greensboro NC

Assignee:

Marion L. Eakes Co. - Greensboro NC

International Classification:

F23J 1100

US Classification:

98115LH

Abstract:

A textile or other industrial machine, of the type where one or a plurality of operations generate a gaseous discharge at a work station, is provided with at least one wall leaving at least one open side and includes an exhaust hood on the top which communicates with the air space above the work station. A first fan communicates with the exhaust hood to withdraw smoke, fumes, vapors and steam from the air space and deliver it to the outside. A second fan draws in fresh, unconditioned outside air and delivers it to a delivery nozzle extending along the front edge of a work table in said work station. An air curtain is thus formed between the delivery nozzle and the aforementioned exhaust hood, whereby the smoke, fumes, vapors and steam are confined within the air space above the work table until withdrawn through the exhaust hood. Further the delivery nozzle provides a surce of fresh air to replace the air withdrawn so that the conditioned air in the workroom surrounding the textile machine is substantially unaffected. In a preferred embodiment, a portion of the exhausted air is recirculated through the air space above the work table prior to being treated by some type of cleaning apparatus, so that the volume of air per unit time passing through the cleaning operation is reduced.
