UNITED STATES WILLIAM H. MALLORY, OF BRIDGEPORT, ASSIGNOR TO HIMSELF, NELSON PATENT OFFICE.

H. DOWNES, AND ROBT. N. BASSETT, OF DERBY, CONNECTICUT.

SPRING FOR UPHOLSTERING PURPOSES.

To all whom 'it may concern:

Beit known that I, WM. H. MALLORY, of Bridgeport, in the `county of Fairfield and State of Connecticut, have invented a new and useful Improvement in Upholstering-Springs;

and I do hereby declare the following, whenV taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full clear, and exact description ofthe same,and which said drawings constitute part of this specification, and represent, 1n-

Figure l a top view, and in Fig.2 aside view, ofthe spring and the manner of forming the same.

My invention is designed as asubstitute for the ordinary upholstering coil-spring; and it consists in forming the springfrom hat orrolled steel wire.

To enable others skilled in the art to construct and use my improved spring, l will proceed to fully describe the same as illustrated in the accompanying drawings.

I first form a hoop from hat or rolled steel wire of sufficient strength, (according to the purpose for which itis to be used,) as denoted in black,Figs.1 and 2. I nextjoin the two opposite sides of the hoop, as denoted in red,by a llexible connection, A, which forms two loops, B B. I then join the two loops, as denotedin blue, Figs. 1 and 2, by a flexible connection, C, like or similar to the connection A. This completes my spring, and is to be inserted inupholstering, or wherever similar springs are required, set in the position as denoted inblue, Fig. 2, and otherwise treated `as the ordinary coil-spring. V I

The advantages of my improved spring are that the sprin gis more elastic, of greater range, is cheaper of construction, and will not set 7 like the ordinary coil-spring.- t

I have described my spring as made of flat steel wire, instead of which the wire may be rolled, corrugated, or concavo-convex, and the wire may or may not be covered.

I have described my spring as applied to upholstering purposes, yet it is not limited in its use, as itmay be applied to any purposes where its form will permit its being used, as carriages, Src., it simply being required `to make the springs of sucient strength for the purpose to which they are to be applied. Therefore, without confining myself to the particularform of the wire or to the purpose for which my spring may be used,

What I claim as new and useful, and desire to secure by Letters Patent, is A spring for upholstering and other purposes, constructed substantially as herein set forth.

WILLIAM H. MALLORY.
