To all whom it may concern:

Be it known that I,'WARDER D. HUNT, av 'citizenof the-.United States of America, and a resident of Cincinnati, in the county of certain new and useful Improvements in Bed- This invention relates to certain improvements in spring bed-bottoms, and more esmattresses which are provided with a covering sheet of woven wire fabric extended across the top; and the object of the inventionis to provide a bed-bottom of this general having means of an improved nature for hold- The invention consists in certain novel features of;- th'e construction and combinations and arrangements of the several parts of the improved spring bedbottom or mattress whereby certain important advantages are strip provided with second bend.

' and Ifinal central crease or bend c -is then- .produced in the folded strip, vas shown in that a U form or hook shape is imparted to them, the free hooked edges of the binding or reinforcing strips projecting toward each other and underneath the woven-wire covering-sheet 7, so as to be in position to be engaged under the projecting parts or flanges 5 of the opposite end rails of the frame for hold. ing ,the said covering-sheet securely in placethereon, the tension'of the coiled-wire strands of which the covering-sheet is formed being4 sufficient to hold the hook-shaped bindings or reinforcing-strips engaged with the oppositely-directed parts or tianges 5 5 of the respective end rails, as will be readily understood. Each of the bindings or reinforces 6 6 along the end edges of the woven-wire covering-sheet is formed from an elongated strip or pieceof sheet metal, such as is shown in det-ail in Fig. 4, this strip havingv a central crease or bend produced in it, as shown at a. in Fig. 5 and indicated in dotted linesin Fig. '4, this central .bend or crease giving to the strip a V shape` in cross-section, as clearly shown in Fig. 5.- The end of the woven-wire covering-sheet 7 is then inserted'between the two plies 10 l0, produced by the central'bend a in said strip, after which the two plies 10 10 are pressed flat upon each other, as indicated in Fig. 6, the end of the woven-wire sheet being thereby flattened out and held between said plies 10. A second central crease or bend b is then produced in the folded strip 6, as indicated in Fig. 7, and the two plies 1l 1l, produced in the st'rip by said second bend orcrease, are also pressed fiat upon each other, as shown in Fig. 8, whereby it will be seen that the end of the woven-wire sheet 6 is securely held between the plies of the folded strip and the roughends of its strands are completely covered up, there being upon one side of the end portion of .the woven-wire sheet a single thickness of the sheet metal of which the binding-strip is formed vand on the other side of said sheet three thicknesses of Asuch sheet metal, produced by the bendingover or lapping of the folded metal strip over upon itself at that side. By this construction the reinforce is made of increased 'strength at the side at which' there are three thicknesses of' the sheet metal, as will .be evident. A third Figs. 2 and 9, and the two plies 12 12 thus v formed are caused to be'extended 'nparallel directions one above theother,so thata U form or hook-shape is imparted to the folded strip secured upon the end of the woven-wire sheet 7 by means'of its several bends. Owing to the several plies of which the completed bindinforce, which is formed, as above stated, of

three thicknesses of sheet-metal, is extended upon the outer or convex surface of the hookshaped folded strip, While the single thickness atthe other side of the strip is caused to extend insidefof the hook -shaped strip, as clearly shown in the drawings. The U-forrn or hook-shaped attaching means thus produced along the opposite ends of the woven` wire covering-sheet are adapted for ready engagement with the overhanging projections at the ends of the frame and formed of the horizontal upper flanges of the Z-bars of which the end rails of said frameare formed, and when said attaching means are engaged with said overhanging parts the resiliency of the coiled wires of which the strands of the woven-wire sheet 7 are formedV will serve to hold said sheet securely in position on the frame. Since the thicker and stronger side ofthe folded metal strip at the outer or convex side of the hook-shaped folded strip, it isevident that such thicker and strongorportion will serve to hold'the endof the Woven- Wire sheet securely and firmly upon the-metal or other frame ofl the bed-bottom and will serve to prevent the end of the woven-Wire sheet from being pulled out of engagement between the plies of the folded strip, as 'it would otherwise be liable todo if the weaker single-ply side of the folded strip were arranged outermost. Then the woven-wire covering-sheet has been attached to the end in some eases be desirable to Hatten out the ICO IIO

rails ofthe frame, as above set forth, it maya' coils of said sheet at the points where they overlie the horizontal upper flanges 5 5 of the .Z-shape end rails of the frame, es indicated at 8 in Fig. 2. The. central portion of aids sheet 7 between the flanges 5 is also supportedabove the planes of the side rails 1, so as to be free for vertical movement under downward strain.

From the above description 'of my improvements it will be seen that the improved bedbottom or mattress' is of an extremely simple and inexpensive nature andis especially well adapted for use, since the bindings or" reinforces at the ends of the woven-wire coveringsheet not onlycove'r the raw ends of the strands and prevent them fromfraying, but 'also form l avery strong and secure means for attaching' the woven-wirel covering-sheet to the frame and also impart a very finished appearance to the bed-bottom. It will also be obvious from'theabove description that the improved bed-bottom or mattress is capable oL very considerable modification without material departure from the principles and spiritof the invention, and for this reason I do not wish to limit myself to the employ` `and loweriianges, each end rail being held `with one of its fianges flush on the side rails and with its otherfiange abovesaid rails and directed away from the end of the frame anda covering-sheet having parts for engagement with' the'- oppositelydirected upper flanges of said" endy rails for the attachment of said sheet to the frame, substantially as set forth.' f
