J. A. WULFTANGE METAL BINDING Fed Aug. 27. 1921 Patented Feb. 26, 1924.
v"rss METAL BINDING.
Application filed August 27, 1921.
To all whom, t may concern.'
Be it known that I, JOHN A. IVULFTANGE, residing at Hamilton, Butler County, Ohio,
a citizen of the United States, have invented certain new and useful Improvements in Metal Bindings, of which the following is a specification.
This invention relates to bindings for metallic receptacles and the like and is particularly adapted for use in connection with the manufacture of wire cloth receptacles and other articles suoli as sieves, corn poppers, etc.
It has been the experience of most every one who has used receptacles and other articles such as are constructed of wire cloth that the bindings 'along the edge frequently break away, come loose from the body portion of the receptacle and expose the hands of the user to the raw edge of the wire body portion. In devices where thewire body portion is soldered to the binding, the wire will break away at the edge of the solder after continued use.
The primary object of this invention is to provide an improved binding for the edge of a metallic receptacle or other article wherein a reinforcing binding strip Ais secured to the edge of the body portion of the receptacle by folding or rolling the two together, thus producing an edge which will be secure and which will permit flexibility of the body portion.
Referring to the drawing wherein a preferred form of this invention is illustrated.
Figure 1 is a perspective view of the top portion of a wire cloth receptacle.
Figure 2 is an enlarged fragmental cross sectional view of the edge of the structure shown in Figure 1.
Like reference characters refer to like parts on both figures of the drawing.
10 designates the body portion of the receptacle which is illustrated as being of wire cloth. 11 designates a metal binding strip for the receptacle. The binding strip is shown as being in two parts. The particular number of parts, however. is not essential. At the points where the ends of the binding come together, they are over-lapped as Shown at 12 (Fig. 1).
The body portion 10 in the completed binding extends up and turns over as at 13 Vwith the folded or rolled portion 14 of the Serial No. 495,968.
metal binding strip. The inner edge 15, of the binding strip 11, presses tightly against the body portion 10 and holds the latter firmly against the unrolled portion of the strip 11. The folded or rolled portion 13 of the body portion 10, being confined within the roll 14 of the binding strip, tends to further hold the strip 11 rigid with the body portion 10.
During the process of manufacture, the binding strip is held firmly against the body portion while the upper raw edge of the body portion and the corresponding edge of the strip are folded or rolled over by suitable machinery orv tools.
If desired, the rolled edge may be flattened against the unrolled portion of the strip 11. This, however, is unnecessary and would cause the binding to lose some of its stiffness.
It will thus be seen that I have provided a binding for receptacles which will protect the edge, hold it firmly against being detached and yet will permit a great amount of misuse due to the fact that the body portion when bent outwardly would turn against the curved under and inner portion of the roll. This would permit of an even bending instead of a breaking as might be the case if the parts were soldered.
While I have described my invention in detail, I desire to have it understood that modification and changes may be made without departing from the spirit of the invention and within the scope of the appended claims.
Having described my invention, what I1 claim is 1. A metallic receptacle having a wire cloth body portion, an edge portion comprising in addition to the edge of the wire cloth, a metal strip, the metal strip and the wire of the wire cloth edge being bent together and on themselves substantially 360o to form a stiffening edge for the receptacle, the edge of the bent portion of the strip being in engagement with the wire cloth, whereby a tendency of the cloth to withdraw causes a binding of the same between two portions of' the strip.
2. In combination, wire cloth, a metal strip at its edge, the outer edgesof the metal strip and the wire cloth being ,bent together, with the metal strip on the outside, and having an iinpinging portion exerting a biting engagement with the body portion.
3. An article having a Wire cloth body, a
metal strip at the edge of the Wire cloth, the
5 edges of the metal strip and the Wire cloth being folded together, the met-a1 strip being folded on the outside of the folded portion of the body, the edge of the foldedV portion Y of the strip turning inward so that it presses the side of the body portionfthereby producing a biting engagement therebetween.
In testimony Whereofl hereunto zi-tix my signature.
