Memo’ ans-Awe ‘ ,BY Patent'ed Sept. 10, 1946 1 2,407,404 .,UNITED STAT-'ESPATENT OFFICE PAD HOLDING AND FEEDING DEVICE Murray Dessaur, Bronx, N. Y., assignor to Murray . Dessaur and Richard D. Gale ‘ Application October 23, 1944, Serial No; 559,972 1 Claim. , , The present invention is directed to an abrasive composition, particularly to the type consisting essentially of steel or similar Wool, usually im pregnate-d with a soap or other detergent. Steel wool of this character has been in com mon use for a considerable time for various pur poses. (Cl. 15-209) 1 . 1 In particular, it has been used for the and such pads be. fed to the work in the quantity and when desired. It is still further among the objects of the pres sent invention to provide a'cleaning device of the character described, which will be convenient for use ~by'the operatorrwithout any danger of splin ters entering lthe ?ngers, and which may be ?rmly held and effectively used by the operator with cleaning of pots and pans where particles of food have become strongly adherent to the utensils in out undue strain on, the muscles of the hand. the process of cooking. Such steel wool, usually 10 ' In practicing the present invention there ‘is in the form of pads,.was effective for the desired provided one or more pads of steel wool prefer purpose but there were a number of disadvantages ably impregnated with a soap or similar composi inherent in the use thereof. It was necessary to tion. The pads are usually cylindrical in form. grasp the pad with the ?ngers, and in the abrad ing action, slivers of metal often entered the ?ngers and caused discomfort and infections. Also, because of the relatively small size and non rigid character of the pad, it was di?icult to hold the same and only the ?nger tips could be used for this purpose. rIlhis made the abrading operation quite di?icult and tiresome. Another di?iculty which was encountered is the fact that a pad of this character wore out rather rapidly and frequent replacements were necessary. There has also been proposed a device for po-l ishing or cleaning surfaces which consisted of a brush mounted on a suitable holder. Means were provided for adjusting the’ extent to which the bristles projected from the holder in order to provide varying lengths of bristles for contact with the surface to be cleaned and polished. Such There is also provided a holder having a cylin drical opening therein into which one or more of such pads is adapted to ?t. This member may be considered as a container for such pads. It is open at both ends, the pads being at one end of the container. At the other end there is provided internal threads and a plunger ‘similarly threaded is introduced into said end. The plungerlhasa' head serving as a support for the hand of the operator in using ithe device. It also serves as a means for rotating the plunger relative to the container to feed additional por tions of the pad out of the end of the container as the pad gradually wears in use. The invention is'more speci?cally ‘disclosed in the accompanying drawing constituting a part cleaning pots and pans, particularly since the hereof, and in which like reference characters in. dicate like parts and in which, Fig. 1 is a transverse cross-sectional View taken through the axis or ,center line of the device, some bristles of a brush are not capable of accomplish- I parts being shown in elevation; a device is not at all suitable for the purpose of ing the desired cleansing operation thereon. Also, the holder was of such a character and extent that it would contact with the interior of the utensils and would interfere with the cleansing, particularly in the corners thereof. The present invention is intended and adapted to overcome the difficulties and disadvantages of the prior art, it being among the objects thereof to provide a steel wool pad combined with a hold ing device such as to allow ready and. convenient cleansing of kitchen utensils or other articles. It is also among the objects of the present in vention to provide a structure of a pad and mounting therefor, such that the life of the pad Fig. 2 is a top plan view thereof; and Fig. ,3 is a view from below showing the end of a pad in position for use. The hollow container I, here shown as cylin drical in form, is provided with threads 2 near the upper end thereof, said threads terminating at 3 just short of the itop end 4 thereof. The base of the threads is approximately in align ment with the inner surface of container I. Said threads terminate at point 5, a substantial dis tance below the top end 4 in order to provide a sufficient number of threads for strength, con venience and stability in the device. The lower portion 6 of container I tapers towards the lower end 1 1thereof so that the thickness at end 1 is is greatly extended without any decrease in the 50 less than the thickness of the body of container 1. effectiveness thereof. This insures that there will be no interference It is further among the objects of the present ‘invention to provide a structure of pad and hold with the operation of the pad in the rubbing or ing device which embodies a magazine so that a A head 8 of any desired form, here shown as abrading operation. plurality of pads may be introduced into the same, 55 cylindrical, has the sides 9 provided with longi 2,407,404 3 tudinal rib portions for the purpose of providing means for a ?rm grasping of the device by the operator. Depending from the lower \face In of head 8 is a plunger l l formed with screw threads along substantially its entire length, said threads cooperating with threaded portion 2 of container I. The lower face l2 of plunger H is slightly . rounded and is smooth. It contacts with pad I13 of steel wool impregnated with a suitable soap. The lower face I4 of pad I3 contacts with a‘simi lar pad [5 in the lower end of container l. The lower face it of pad I5 is lcaused to extend a short distance beyond end 1 of container I. Usu ally thedistance between the end 5 of the threads and end 7 of the container is such that when plunger ll is in its upper position, all pads are 4. container 1 need not be cylindrical in form as the outer surface may be of any shape. Also, it may be provided on the outer surface with rough ened portions or knurling to facilitate the holding of the device. The integral opening need not be cylindrical in form, although the threaded por tion 2 is necessarily cylindrical. The pads may be of a shape to conform with the opening in the lower part of container |. Any suitable material may be used for both the container and the plunger and it has been found that certain plastic substances are eminently suitable for the purpose. Such materials are sanitary, have su?icient strength for the purpose, are easily formed into the desired con?gurations, and are highly deco rative. If desired, metal may be used for the sev eral parts or other substances such as compressed conveniently contained in the device. ‘ In the operation of the device for cleaning pur ?brous materials. These and other changes in the details of the poses, the position of the several parts is approxi mately that shown in Fig. l. The head 8 is 20 practice of the invention may be made within the ' spirit thereof and the invention is to be broadly grasped in the palm of the hand, the depressed construed and not to be limited except by the potion is allowing a‘ better ?t thereof in the hand. The ?ngers of the operator are closed around the character of the claim appended hereto. container 1, thus giving a ?rm hold on the device. I claim: A pad holding and feeding device comprising It may then be used for the cleansing operation an elongated hollow cylindrical container open at without any undue fatigue being caused to the both ends, the inner surface thereof at the upper operator. As the end It of pad i5 wears down, end only being threaded, an externally threaded head 8 is turned to cause plunger H to move downwardly in container l and thus present plunger cooperating with said threaded surface, fresh portions of the pad Hi to the work. When , the diameter of said plunger being uniform pad I5 is approximately consumed, pad 13 had throughout its length except the lower end there moved down so that its lower face 14 is near the end ‘I of container I. Plunger II is then removed by backing off from threads 2. A new pad is in— troduced into the top 4 of container I and pressed down by the plunger which is then threaded into the container until lower end [4 of pad l3>extends beyond end ‘I of the container. The device is then again ready for use. There is usually provided in head 8 a transverse cylindrical opening IT. A handle I8 is ?tted therein. This handle may be used for hanging the device over a kitchen sink or other convenient place. This may be conveniently done because there is no absorption of liquid by the pads and there is no dripping of liquid therefrom when the device is hung up. Although I have described the invention setting forth a single embodiment thereof, it will be ap parent to those skilled in the art that many vari ations in the details of construction may be made within the spirit of the invention. For instance, of which is slightly less in diameter so as not to contact with said threaded surface, a head on the top of said plunger of larger diameter than the threaded portion of said plunger, the inside sur face of the lower end of said container and the outside surface of said lower end of said plunger both being smooth, a plurality of steel wool pads in said lower end of said container and placed in end to end contact, the diameter of said pads being equal to that of said lower end of said con tainer, the inner end of the inner pad contacting the lower end of said plunger and the outer end of the outer pad protruding outward from the lower end of said container, said plunger having longitudinal and rotational movement relative to said container to cause the lowermost pad to protrude from the lower end of the container as the steel wool extending from the container is consumed.
