1. Field of the Invention
This invention relates to a liquid agitating apparatus having a reciprocating armature motor that imparts a vibratory motion to a liquid, such as a solvent, in a chamber to clean matter from objects such as paint brushes.
2. Description of the Related Art
In the past, the cleaning of brushes has been difficult. One soaked them in a solvent to soften the paint and then attempted to work the paint out of the bristles by hand. This method did not always satisfactorily clean the brush and it was somewhat damaging to the hands.
U.S. Pat. No. 2,896,649 to H. C. Faidley on July 28, 1959 describes an apparatus for cleaning by ultra-sonic vibrations having an ultra-sonic unit encased in a plaster of paris container, placing a solution in a solution container above the plaster container and pulsating the solution to clean items in a basket.
U.S. Pat. No. 3,399,869 to W. J. Loria, et al., on Sept. 3, 1968 show an electromagnet that pulsates and periodically allows a perforated plate to be expelled from and drawn back to the bottom of a container so as to create air bubbles through the holes in the plate as a solution passes through the holes.
U.S. Pat. No. 3,596,883 to K. H. Brech on Aug. 3, 1971 describes an ultrasonic cleaning apparatus that has a plurality of electroacoustic transducers attached to a container to cause cavitation of a liquid in the container.
