## Title
Horizontal centrifugal device for moisture removal from a rug

## Abstract

A device for removing moisture from a rug or other item, such as a tent or a tarp, etc. in a short time while preventing compression of the rug or the item and the resultant crushing of fringe comprising a shaft disposed on a horizontal axis having a large diameter with a rotatable smaller diameter inner tube therein, the smaller diameter inner tube having apertures therethrough, the smaller diameter inner tube being open at both ends, the inner tube being driven to rotate, and fluid removal means connected to the larger diameter tube for removal of fluid from the device, whereby when a wet rug is loaded into the smaller diameter inner tube, and rotated the moisture in the rug is spun from the rug through the apertures into the larger diameter outer tube and the moisture is drained from the device. A wet item can be loaded from either end and the item can be unloaded from either end after the moisture has been removed.

## Background
REFERENCE TO RELATED APPLICATION
This application claims the benefit of provisional patent application No. 61/002,333, filed Nov. 8, 2007.


BACKGROUND OF THE INVENTION
The field of the invention pertains to rugs, such as oriental rugs and area rugs, and, in particular, to a device for removing water from large items, i.e., rugs that are wet from washing.
Compression wringers, mechanical vacuums, and drip drying on poles are techniques that can be used for rugs that are wet from washing.
For example, a wet rug is compressed or squeezed in an attempt to remove moisture from the wet rug. A vacuum can be used to vacuum moisture from the rug as the rug lays flat. The wet rug is suspended on poles to allow the moisture to drip from the rug.
A rug that is still wet is quite heavy and difficult to position on poles. Another problem is that when a wet rug is hung on poles the moisture will drip on the floor and puddle, creating additional humidity as well as potential injury problems from slipping. When a wet rug is vacuumed to remove moisture the underside remains wet and would need to be elevated for drying in order to prevent fungal growth.
Elevating a very wet rug causes unwanted, unremoved soil to gravitate (migrate) to the ends of the vertical drying rug on pole, thus creating an additional step to process the soiled/discolored fringes.
A problem with compressing or squeezing a wet rug is that when a rug is compressed the fringe is also compressed requiring time and effort to straighten the fringe. Moreover, another step of combing/detailing may be required to straighten the fringe. Additionally, the fringe can be damaged if mechanical combing is required.
A need existed for a device that allows the removal of most of the water from a large rug without crushing or compressing the rug or creating discomfort to the operator/person performing the rug cleaning services. A need existed to remove moisture form a wet rug without crushing the rug and hence crushing the fringe of the rug. There existed no dual port device for loading rolled wet rugs. There existed no 14′′-20′′ cylinder driven by a drive system that allows for loading a wet rolled rug.
A need existed for a device to evacuate water quickly (along with soluble soil) out at the closest exit (the pile yarn). This is in contrast to other systems that require water and soil to be squeezed through the entire rug, or water to migrate throughout the length of the rug.
SUMMARY OF THE INVENTION
The invention is a device for removing moisture from a wet rug or other item, such as a tent or a tarp, etc. in a short time while preventing compression of the rug or the item and the resultant crushing of fringe. The invention comprises a shaft having a large diameter with a rotatable smaller diameter inner tube therein, the smaller diameter inner tube having apertures therethrough, the smaller diameter inner tube being open at both ends, the inner tube being driven to rotate, and fluid removal means connected to the larger diameter tube for removal of fluid from the device. The device is horizontal and low to the floor.
When a wet rug is loaded into the smaller diameter inner tube, and rotated the moisture in the rug is spun from the rug through the apertures into the larger diameter outer tube and the moisture is drained from the device. The tube can have an epoxy finish to aid loading and unloading. A wet rug can be loaded from either end and the rug can be unloaded from either end after the moisture has been removed. The dual ports allow for positioning the machine in various locations. The device solves the need for removing moisture from a wet rug or items.
The drive system for rotating the smaller diameter tube employs drive wheels (of compound polymer polyurethane composite), bearings and drive system (motor) to rotate the smaller diameter tube at a high RPM (750-1200 RPMs).
In operation, the wet rug or other item is loaded from either open end of the device into the inner tube of the device. The device is powered and the inner tube starts rotating. As the inner tube rotates with the wet rug therein, the moisture is spun by centrifugal force to the outside of the inner tube. The moisture leaves the inner tube through apertures in the tube. The moisture is forced by centrifugal force into the larger diameter shaft. The larger diameter shaft is sealed but has a drain system for removal of accumulated fluid from within the shaft.
The rotation of the inner tube is caused by a motor driving roller wheels for turning the inner tube. A drive belt connects with the motor with the drive wheels. Roller wheels act as bearings for the inner tube and move the inner tube smoothly. Dynamic braking of the inner tube is caused by stopping the drive motor.
Thus, the wet rug or other item contained within the device has most of the moisture removed from it by being placed in the device and being rotated for a few minutes.
Loading the rug is also facilitated by open ends. Removing the rug from the device is facilitated because open ends allowing pass through of the rug. The horizontal orientation of the device further facilitates loading and removal of the rug or item. A pusher or puller can be employed for loading or unloading the rug or other item.
