BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 503,540, dated August 15, 1893.

Application filed October 10, 1892. Serial No. 448.285- (No model.)

To coll whom t may concern.-

Be it known that I, CHARLES M. HUNT, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Bed- Bottoms; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has forits object to econoinize space in the matter of transportation and storage of woven-wire bed-bottoms, as well as to provide for the setting up of such bed-bottoms without the aid of a stretching machine; and it consists in certain peculiarities of construction and combination of parts constituting a knock-down device of that character, as will be hereinafter described with reference to the accompanying drawings and sub- "sequently claimed.

In the drawings: Figure l represents an inverted plan view of a bed-bottom constructed according to my invention and partly setup; Fig. 2, a similar view of the same complete; Fig. 3, a vertical longitudinal section taken on line 3-3 of the preceding figure; Figli, a plan view of the separable parts constituting the bed-bottom, and Fig. 5, the bedbottom rolled up for transportation or storage.

Referring by letter to the drawings,'A represents the side-rails, B the end-bars, C the woven-wire fabric and D the bindingstrips constituting my improved bed-bottom. The side-rails and end bars are provided with registering bolt openings, preferably arranged in pairs, those in said side-rails being also preferably countersunk at their lower ends to conceal nuts on bolts hereinafter described. At least one of side-rails consists of two sections hinged or otherwise flexibly connected in such a manner as to have the joint open outward, as best shown in Fig. l, and primarily fast to the under side of one of the sections is a stay-plate E that is designed to overlap and be fastened to the other of said sections when the aforesaid joint is closed, as clearly illustrated in Figs. 2 and 3. The woven-wire portion of the bed-bottom hasits ends held between the bars B and strips D, and for shipment or storage the side-rails are rolled up with the parts aforesaid, as shown in Fig. 5, whereby I economize considerable space, and am thus enabled to effect a saving in the matter of freight and warehouse charges.

To set up the bed-bottom the side-rails and end-bars are primarily united by pivots, such as the bolts F herein shown, and if both of said side-rails be jointed, one of them is first extended its full length and thus maintained, although it is perhaps preferable to have this side-rail in one piece. The parts being thus joined they are practically in the position shown in Fig. l, the w0ven-wire fabric being unstretched. To stretch the woven-wire fabric, the joint of the other side-rail is closed by pressure against the hinged sections, after which the hitherto free end of the relative stay-plate is made fast by nails, screws or other suitable means, and stay-bolts G are engaged with both side-rails and end-bars to prevent the same from having play on the pivots above specified.

Frein the foregoing it will be seen that each bed-bottom is provided with its own stretcher and therefore I do away with the necessity for stretching machines commonly employed in the manufacture of woven-wire bed-bottoms.

WVhile I have shown and described a stayplate for a jointed side-rail I do not wish to be understood as limiting myself thereto, but such a device is preferable as a means for bracing the joint of said side-rail. I also desire it understood that the stay-bolts may be omitted without departure from what I consider is the essential features of my invention.

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

l. In a bed bottom, arranged for folding and rolling, the combination of the wovenwire fabric C, secured to the end bars B, by

means of the binding strips D, the side rails A, connected with the end bars by pivot bolts F, passing through openings in the ends of said bars and rails, and one of said side rails being formed in two sections having a hinged or other iieXible connection, the joint ar- IOO ranged to open outwardly, and on the under side of one section a stay-plate E, provided with openings for` securing nails or screws, overlapping and attaching to said other Section, all as described.

2. In a bed bottom, capable of being folded and rolled up, in combination with the Woven-1 wire fabric C, secured to the end bars B, by the binding strips, the said binding strips D,` the said end bars pivotally connected withl the ends of the side rails, the pivot pins F, and the side rails A, one formed in two hinged sections, the perforated stay plate E, an'

ranged to connect said sections, and stay bolts G, passing -Jthrough the ends of the side rails and end bars, when the bed bottom is extended, all constructed, arranged and operating n
