Abstract

Abstract A method of abrading fabric garments in a washing machine. The garments are placed in the washing compartment of a washing machine and the machine is filled with sufficient hot water to cover the garments. The garments are thoroughly soaked, and then the compartment is drained of sufficient water to enable the compartment to accept a predetermined amount of small sized abrasive particles to uniformly abrade the garments. The abrasive particles are added to the compartment and agitated until the garments are uniformly abraded. Next the compartment is drained of substantially all of the water and abrasive with the drainage fluid passing through a filter or trap capable of separating the abrasive from the water; rinsing and redraining are accomplished, and the sand removed from the filter for reuse in subsequent abrading operations.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 128 words
A method of abrading garments in a conventional household or commercial automatic washing machine which comprises the steps of: a. placing said garments in a receptacle of said machine capable of agitation of said garments within said receptacle; b. adding a predetermined amount of abrasive particles to said receptacle, said particles being less than 2 millimeters in diameter, said predetermined amount of particles sufficient to uniformly abrade said garments; c. further adding to said receptacle a first liquid sufficient to circulate said abrasive particles within said receptacle; d. agitating of said garments until said garments are uniformly abraded; e. draining said receptacle through said machine's conventional drainage system of substantially all of said first liquid and said abrasive particles; f. removing said uniformly abraded garments from said receptacle.
Claim 2
Independent Claim 128 words
A method of abrading garments in a conventional household or commercial automatic washing machine which comprises the steps of: a. placing said garments in a receptacle of said machine capable of agitation of said garments within said receptacle; b. adding a predetermined amount of abrasive particles to said receptacle, said particles being less than 2 millimeters in diameter, said predetermined amount of particles sufficient to uniformly abrade said garments; c. further adding to said receptacle a first liquid sufficient to circulate said abrasive particles within said receptacle; d. agitating of said garments until said garments are uniformly abraded; e. draining said receptacle through said machine's conventional drainage system of substantially all of said first liquid and said abrasive particles; f. removing said uniformly abraded garments from said receptacle.
Claim 3
Dependent Claim 24 words
The method of claim 1 wherein said draining step is accomplished through a filter means capable of separating said first liquid from said particles.
Claim 4
Dependent Claim 88 words
The method of claim 2 further comprising the following steps prior to said removing step of at least a first filling said receptacle with a second liquid sufficient to cover said abraded garments; at least a second agitating of said receptacle until said abraded garments are thoroughly rinsed with said second liquid; at least a second draining of said receptacle of substantially all of said second liquid and substantially all of any residual amount of said particles; said second draining step to be accomplished through said filter means.
Claim 5
Dependent Claim 24 words
The method of claim 2 further comprising the steps of collecting said abrasive particles from said filter means for reuse in subsequent abrading operations.
Claim 6
Dependent Claim 13 words
The method of claim 1 wherein said first liquid contains a cleaning medium.
Claim 7
Dependent Claim 15 words
The method of claim 1 wherein said small sized abrasive particles are pumice sand particles.
Claim 8
Dependent Claim 18 words
The method of claim 1 wherein said predetermined amount of abrasive particles is packaged in a soluble membrane.
Claim 9
Independent Claim 158 words
A method of abrading garments in a conventional household or commercial automatic washing machine which comprises the steps of: a. placing said garments in a receptacle of said machine capable of agitation of said garments within said receptacle; b. adding to said receptacle a sufficient amount of a first liquid to thoroughly soak said garments; c. a first agitation of said garments within said receptacle; d. further adding to said receptacle a predetermined amount of abrasive particles, said particles being less than 2 millimeters in diameter, said predetermined amount of particles sufficient to uniformly abrade said garments; e. a second agitation of said garments until said garments are uniformly abraded; f. draining said receptacle of substantially all of said first liquid and said abrasive particles; said draining step is accomplished through said machine's conventional drainage system and a filter means capable of separating said first liquid from said particles; g. removing said uniformly abraded garments from said receptacle.
Claim 10
Independent Claim 158 words
A method of abrading garments in a conventional household or commercial automatic washing machine which comprises the steps of: a. placing said garments in a receptacle of said machine capable of agitation of said garments within said receptacle; b. adding to said receptacle a sufficient amount of a first liquid to thoroughly soak said garments; c. a first agitation of said garments within said receptacle; d. further adding to said receptacle a predetermined amount of abrasive particles, said particles being less than 2 millimeters in diameter, said predetermined amount of particles sufficient to uniformly abrade said garments; e. a second agitation of said garments until said garments are uniformly abraded; f. draining said receptacle of substantially all of said first liquid and said abrasive particles; said draining step is accomplished through said machine's conventional drainage system and a filter means capable of separating said first liquid from said particles; g. removing said uniformly abraded garments from said receptacle.
Claim 11
Independent Claim 254 words
A method of abrading fabric garments in a washing machine which comprises the steps of a. placing said garments in an agitating compartment of said machine; b. filling said compartment with sufficient hot water to cover said garments; c. soaking and agitating said garments in said water in said compartment until said garments are thoroughly soaked; d. draining sufficient water from said compartment to enable said compartment to accept a predetermined amount of pumice sand and soap to uniformly abrade and clean said garments, said sand having a particle size less than 2 millimeters in diameter; e. adding said sand and said soap to said compartment; f. agitating said garments, said water, said sand and said soap in said compartment until said garments are uniformly abraded and cleaned; g. draining said compartment of substantially all of said water, said sand, and said soap; said draining step to be accomplished through said machine's conventional drainage system and a filter means capable of separating said sand from said water and said soap; h. refilling said compartment with cold rinse water sufficient to cover said abraded and cleaned garments; i. agitating said rinse water and said abraded and cleaned garments until garments have been throughly rinsed; j. redraining said compartment of substantially all of said rinse water, said redraining step to be accomplished through said drainage system and said filter means; k. removing of said abraded and cleaned garments from said compartment; and l. collecting said sand from said filter means for reuse in subsequent abrading operations.
