CUSHIONlNc-BODY.

srEcIFIeATIoN forming part of Letters Patent No. 659,266, dated october-9, ieoo.

Application tiled February v12, 1900. Serial No. 4,987. (No model.)

To @ZZ whom t may connerie:

Be it known that I, ROBERT IsAAO STEWART, residing at Xenia, in the county of Green and State of Ohio, have made certain new and useful Improvements in Cushioning-Bodies, of which the following is a specification.

My invention is an improvement in cushioning-bodies formed of corrugated sheets and adapted for use in egg-crates and in packing bottles and other fragile articles and which may be used for any other purpose desired. The invention relates particularly to constructing such corrugated sheet so the corrugations will be held or maintained in the desired form, and particularly so such sheets when formed of a plurality of layers will not be subject to have the layers separate in such manner as to open the sheet.

The invention consists in the improvements hereinafter described and claimed.

In the drawings, Figure 1 is a face view of a sheet in which one edge of the corrugated sheet is bent back upon itself in acurved form, forming, practically, a circular roll at the edge of the sheet. Fig. 2 is an edge view of the sheet shown in Fig. l, and Fig. 3 is a detail section on about line 3 3 of Fig. 1. Fig. 4 is a face view, and Fig. an edge view, of a corrugated sheet in which the sheet is bent back upon itself in the form of an angular fold. Fig. 6 is a face View, and Fig. 7 an edge view, of a corrugated sheet in which the edge is maintained by a bend in the form of a crimp, the sheet being bent transversely of the corrugations, but the bend not extending to such an extent as to return the sheet upon itself, as indicated in Figs. 2 and 4. Fig. 8 is a face view of a corrugated sheet in which the corrugations are held together by means of keys formed by punching portions of the corrugations through the sheet from one side to the other. Fig. 9 is a detail sectional view on about line 9 9 of Fig. 8, and Fig. 10 is an edge view of the cor-` rugated sheet shown in Fig. 8 and looking at the end of the corrugation.

My invention is especially applicable to cushioning bodies in which the corrugated sheet is composed of a plurality of layers of paper itted face to face and corrugated jointly, because in such construction it is not only desired to maintain the corrugationsgin the form in which they are 1nade;jbut it is also desired to prevent the sheets orlayers from separating at the edges of thecushionin g-body or elsewhere throughout such body. It is for this reason that I preface what I; am about to describe with the statement Y that my invention is speciallyadapted or kapplicable to such forms of cushioning-bodies ;,but I do not wish it understood that I limit myself to such duplexform of corrugated sheet, as the invention has a broader application to corrugated sheets generally.

My invention, as presently described, seeks to eect the desired end without the necessity of any separate fastening means, or, in other words, I aim to maintain the corrugated sheet in the desired form by a construction of the sheet itself. Another broad linderlying feature of my invention is the fact that I secure the corrugated sheet in the desired form by deliecting a portion of such sheet laterally to the plane thereof. Withk this understanding of the broad principles of my invention I will proceed to describe the constructions illustrated in the drawings.

In Fig. l the corrugated sheet A is-composed of a plurality of layers A', and the sheet has its edge at A2 bent back upon itself in curved form to such an extent as to produce practically a circular roll at the edge of the corrugated sheet and at the end of the corrugations, the roll A2 extending transversely of the corrugations, as shown in the drawings.

In Fig. 4 the corrugated sheet B has its edge B transversely of the corrugation bent back upon itself in 'the form of an angular fold. This construction is similar to that shown in Fig. l in that the corrugated sheet is held in form by bending the edge thereof laterally to the plane of the sheet.

In Fig. 6 the corrugated sheet C is shown as maintained by a bend Cin the form. of a crimp,such bend being extended transversely ofthe corrugations, but not to such an extent as to return the sheet upon itself, as is indicated in Figs. 2 and 5.

In the construction shown in Figs. 8, 9, and l0 the corrugated sheet D is held in the desired form by punching portions D through IOO the sheet from one side to the other, so they will operate as keys to prevent the corrugations from opening, and thus serve to maintain the corrugations in the desired form.

Itis obvious from the foregoing that the several features of the different forms illustrated are so related that they fulfil the requirements of the broad principles involved in my invention, as the several constructions operate to maintain the corrugated sheet in the desired form without the use of separate fastening means and also attain sueh end by deiiecting or bending a portion or portions of the corrugated sheet laterally to the plane thereof.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A cushioning-body composed of a series of layers corrugated jointly and forming a flexible corrugated sheet and bent back upon itself at its edge transversely to the length of the corrugations substantially as set forth.

2. A cushioning-body composed of a iieXible Corrugated sheet bent back upon itself at its edge transversely to the corrugations substantially as set forth.

3. A cushioning-body composed of a ilexible corrugated sheet provided with a portion deiiected laterally to the plane of such sheet whereby the corrugations will be heldin form independently of any separate fastening means substantially as set forth.

4. A cushioning-body comprising a plurality of layers of paper corrugated jointly forming a flexible corrugated packing-body and bent transversely of said corrugations whereby the layers are locked together in the corrugated form substantially as set forth.

5. A cushioning-body composed of a plurality of sheets or layers corrugated jointly forming a cushioning-body, said layers and corrugations being held in form independently of separate fastening means substantially as set forth.
