PROCESS OF CLEANING FURS, FABRICS, AND THE LIKE Filed March 10, 1928 jiwwzz aa Patented Feb. 18, 1930 UNITED STATES PATENT OFFICE BENJAMIN M. SA'VIT'I, OI MINNEAPOLIS, MINNESOTA PROCESS OI CLEANING IURS, FABRICS, AND THE LIKE Application filed March 10, 1928. Serial No. 260,794.
My invention relates to an improved process of cleaning furs, fabrics and similar articles and is especially well adapted for cleanin fur garments having fabric linings or fa ric garments having fur linings or for' cleaning rugs, robes and the like having fabric linings.
My improved process provides for the.
improved process, like characters indicate like parts throughout the several views.
Referring to the drawings: Fig. 1 is a view of a rotatable drum partly in elevation and partly in longitudinal central section;
Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1, on an enlarged scale; and
Fig. 3 is a transverse section taken on the line 33 of Fig. 1, on an enlarged scale.
In carrying out the improved process, there is used a flexible container or bag 4 of duck or other suitable material in which a garment or article w to be cleaned is placed as an entirety. For the sake of brevity, the article will hereinafter be referred to as a fur garment.
Also placed in this bag 4 with the garment w is a given quantity of a cleaning medium preferably sawdust g which has been previously saturated with a given quantity of cleaning fluid such as gasoline. The bag 4 is then tied and placed in a non-flexible container, as shown in the drawings, in the form of a drum 5 mounted to turn about a horizontal axis and having at one end a compartment 6 and at itsother end a compartment 7. That portion of the periphery of the shell of the drum 5 forming the compartment 6 is imperforate and that portion of said shell forming 4: is laced in the compartment 6. Access may had to the two com artments .6 and 7 through normally closed oor openings 8 in the heads of the drum 5.. This drum 5'is the compartment 7 is perforated. The bag rotated at the proper speed by'a driven belt,
not shown, which runs over a pulley 9 on one of the trunnions of said drum. I
The tumbling of the bag 4 in the com artment 6 produced by the rotation of the drum 5 causes the cleaning medium, to wit: the
treated sawdust y to thoroughl mix with 'the fur, enter all creases and olds in the fabric and be moved in all directions over the fur and fabric to roduce a scouring action on the fur and fa bric and thereby thoroughly clean the garment m.
The length of time the bag is tumbled in the compartment 6 depends upon the condition of the article to be cleaned. After the garment a; has been thoroughly cleaned, the
bag 4 is removed from the compartment 6 through the respective door opening 8 and the garment a: removed from the bag 4. Said garment is then placed in the compartment 7 and tumbled therein under the rotation of the drum 4 a sufficient length of time to shake and remove all. of the sawdust from the garment as and which sawdust is reoipitated through the perforated shell of t e compartment and onto the floor or into a box or receptacle placed under the compartment 7 to receive the same.
The above described process has, in actual usage, proven highly eflicient for the purpose had in view and the cost and work in cleaning articles of the class above referred to have been materially reduced.
It is, of course, understood, that various different kinds of cleaning fluids may be used in connection with sawdust or any other cleaning medium.
What I claim is: a
1, The process of .cleaning consisting in confining an article within a limited space. with a bath of sawdust saturated with a cleaning material, tumbling within a larger space said confined article and sawdust to cause distortion of the article and intimate contact thereofwith the sawdust, and in thereafter removing said article from the sawdust bath 95 and removing the adhering sawdust.
2. The process of. cleaning consisting in confinin an article within a limited space with, a: am of: sawdust saturatedflwith a cleaning'materiahtumbling within a larger 1 0 space said confined article and sawdust to cause distortion of the article and intimate contact thereof with the sawdust, and in thereafter removing said article from the sawdust bath and tumbling it in said larger space to remove the adhering sawdust.
