IiEETAFa-WOQI: UTENSIL.

Application filed September 14, 1922. Seriai Ho. 588,232.

To all whom it may concern:

Be it known that we, JOHN J. MORIARTY,

a subject of the King of Great Britain, and

ALAN W. WENTZ, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Metal-Wool Utensils, of which the following is a specification.

This lnvention relates to utensils for scouring and the method of making same, and especially relates to utensils of this character in which metal wool is employed as the scouring agent.

The object of the invention is to provide a simple and effective holder or back for the metal wool of a character which will 'have sufficient ri idity to maintain the utensil in substantially original shape and which will provide a convenient means for grasping the utensil without the necessity of bringing the hand of the user in direct contact with the metal wool.

' A further object of the invention is to provide a binder for the metal wool of a character which will retain the wool in compressed state during use.

In the accompanying drawings: Fig. 1 is a perspective view of embodying the improvements.

Fig. 2 is a sectional view of the same.' Fig. 3 is a section of aportion of the dies employed in the manufacture of the utensil. v

Fig. v4 is a side-view of the press which receives the dies with the dies shown in position therein. v

For the scouring agent of our improved .a utensil utensil we preferably employ metal wool 40 mixed withan adhesive material, as indicated at 1, the metal wool being preferably commercial steel wool and theadhesive material rubber cement or other suitable .rubbercom ound. For the back or holder we refera ly employ a rubber compound 2; he rubber compound which forms the back in a plastic state together with the .hesive mingled therewith.

Wool are placed in layers of suitable thickness in the opening 3 of the femalememher 4 of a die and, compressed by the projection 5 of the male die member 6. The die members are equipped with a plurality of apertures and projections so that a plurality of utensils may be madeat a single operation of the press which is shown in Fig. 4, the die members being placed between the stationary head 7 and the inovable platen '8, which platen is connected with the piston 9 of a cylinder 10, the piston being operated by hydraulic power, 6 compressed air or other suitable means. The head and platen are of a hollow character to receive steam for yulcanizing the product in the dies.

In compressing the mass a certain proportion of the rubber compound will permeate the steel wool mass so as to act as an adhesive element. and the mass of wool is also preferably first dipped in rubber cement or other soft plastic rubber compound.

Aftercompression the articles are vulcanized in a suitable vulcanizer and as a're-' suit a back for the wool is secured with suflicient rigidity to hold the mass of metal wool in its original shape after vulcanization for scouring purposes, the wool itself being held in a compact mass by the ad- The back also furnishes the means whereby the utensil may be grasped by the user.

Having thus' described our invention, we claim:

In. a utensil of the character described, a mass of metal wool, an adhesive element of rubber compound intermingled with said wool, a back for said mass of wool and adhesive element formed of rubber compound, said back, wool and adhesive element being held in a compact mass by vulcanization.

In testimony whereof, we have hereunto set our hands this 13th day of September, 0

JOHN J. MORIARTY. ALAN W. WE-NTZ.
