Cleaning system

Abstract

A cleaning system has a high velocity fan held within an air-directing casing movably mounted between the lower ends of an inverted U-shaped yoke. The blade configuration of the fan assures that air is directed outwardly in a narrow beam. The system rotates about a vertical extendable support tube and the casing and fan oscillate about a horizontal axis through a vertical angle which can extend from horizontal to near-vertical in the upper and lower direction. A crank arm connects to the U-shaped yoke and to one end of a crank rod which connects to the fan casing. Rotation of the crank arm displaces the crank rod so that the casing and fan oscillate about the horizontal axis. The crank arm is adjustable in length by spaced apart holes. The length of the crank rod is adjustable by using a two piece crank rod with the free end of each crank rod piece being adjustably secured to a connecting rod. The newly designed crank rod having additional spaced apart holes provides additional adjustability features.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to universally mounted fans and more particularly to an improved construction for such fan use in textile mills, laundries or any other operation where removing lint from ceilings, walls, floors and machinery is desired. [0003] 2. Description of the Prior Art [0004] Lint accumulation in textile mills and laundries on machinery, ceilings and walls is to be avoided wherever possible. Air blasts and traveling cleaners have been extensively used for this purpose, and some cleaners have been specifically designed for sweeping floor and aisle areas. [0005] Air blast fans have, for the most part, been effective in keeping lint collection off machinery, ceilings and floors especially when they are placed in groups with other fans, however they are limited to an area or pattern where cleaning takes place because of the structure on which they are positioned. They can be programmed to cut off whe...

AI Technical Summary

Benefits of technology

"The present invention is a cleaning system with a high velocity fan that is held within an air-directing casing and moves in a horizontal beam. The system is designed to be adjustable to change the length of the crank rod, which connects the fan to the yoke. This allows for consistent adjustment of the entire structure without replacing parts. The crank arm has additional adjustability features, and one or more extendable sway braces can be used to adjust the support tube, sway braces, and crank rod. The new crank arm has additional adjustability settings. The invention also includes a two-piece crank rod with an adjustable connecting rod, adjustable support rod and sway braces, and a new crank arm with adjustable settings. The technical effects of the invention include improved efficiency and time savings, consistent adjustment of the entire structure, and greater flexibility in adjusting the crank rod length."

Problems solved by technology

Air blast fans have, for the most part, been effective in keeping lint collection off machinery, ceilings and floors especially when they are placed in groups with other fans, however they are limited to an area or pattern where cleaning takes place because of the structure on which they are positioned.

However when a more deliberate, different pattern is desired, the crank rod will need to be changed to a different length thus requiring major down and maintenance on the fan.
