SPRING BED-BOTTOM.

Specification of Letters Patent.

Patented June 12, 1906.-

To all whom, it may concern:

Be it known that I, JOHN G. SMITH, a citizen of the United States, residing at Chicago Heights, county of Cook, State of Illinois, have invented a certain new and useful Spring Bed-Bottom, of which the following is such a full, clear, and eXact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention consists in part in the combination, with a frame, of a plurality of substantially parallel spring-wires provided with loops and one or more corrugated wires extending substantially at right angles to said affixed hereto.

first-named wires and loops thereof.

L '..My invention also consists in certain other novel features and details of construction, all of which Will be described in the following specification and pointed out in the claims In the' accompanying drawings, which illustrate some forms of spring bed-bottoms made in accordance with my invention, Figure 1 is a top plan view. Fig. 2 is an enlargedisometric projection of the corner of the frame shown in Fig. 1. Figs. 3 and 4 are an end view and a side view, respectively, of the parts shown in Fig. 2. Fig. 5 is a to lan view showing a modified form of be ottom. Fig. '6 is a cross-section ofthe form l Y of bed-bottom shown in Fig. 5. Fig. 7 is a cross-section of the frame of a bed-bottom,

` showing a still further modication. Figs.

8 and 9 are detailed views showing the manner of forming the wire fabric for the formation of the bed shown in Fig. 7; and Fig. 10 is a top plan view showing a bed similar to that shown in Fig. 7, but provided with a modified form of fabric and having one end folded up. Fig. 11 is a cross-section of the bed shown in Fi 10, both ends folded up. Fig. 12 is an enIarged view showing a detail of construction. Fig. 13 is a top plan view showing a modified form of spring bed-bottom. Fig.

. 14 is an enlarged view of the fabric shown in Fig. 13, and Figs. 15 and 16 are enlarged views showing modifications.

Like marks of reference refer to similar parts in the several views of the drawings.

Referring-first to Figs. 1 to 4, 15 represents end rails preferably formed of angle-iron.

passing through the ner-pieces 17. These pockets 1 9 are formed by side flanges 20, a top flange 21, and a bottom flange 22. may either be held in position simply by the tension of the wire fabric secured to the end The corner-pieces and siderails rails 15, as will be hereinafter described, or

the corner-pieces may-be shrunk upon the ends of the side rails, so as to be practically formed integral therewith. 23 represents lugs extending from the sides of the cornerpieces 17 Each of the corner-pieces 17 is also provided with a hooded projection for securing it to the head or foot piece of an ordinary iron bed. This projection is preferably made of a bolt 24,passing through the back of the corner-piece 17 and secured in position by means of a nut 25, so that it is both removable and adjustable. 13, Fig. 12, represents a portion of the head or foot piece of thebed. The

head or foot piece 18 is provided at each end with an inwardly-projecting portion 14, in'

which is formed a dovetailed opening 15. These openings 15 are usually about of the form shown in Fig. 12. They, however, vary tion would not fit the various sizes. Owing to the fact, however, that the projection 24 is adjust able, the-projection maybeused with any-sized opening, and the parts may bepermanently drawn together by turning the nut 25. The end rails 15 have formed in them at regular intervals openings 26 to receive the end of longitudinal spring-wires 27. These spring-Wires 27 have formed in them at regular intervals loops 28. The loops 28 are all .85 vconsiderably in size, so that a fixed projec" turned in the same direction, and the portions 29 between the loops are curved. These portions 29 may either be curved in the same direction as the loops, as shown in Figs. 1, 4,

IOO

and 5, or they may be curved in the opposite direction, as shown in Fig. 10. The direction in which the parts 29 are curved de ends upon whether a stiffer or more elastic abrio is desired. If a stiffer fabric is desired, the

parts 29 are curved in the same direction as the loops, as shown in Figs. 1, 4, and 5, While `if a more elastic fabric is desired they are .nnm A curved in the opposite direction,- as shown in Fi 10.-

designates corrugated transverse wires which ass through the loops 28 of the Wires 27. T ese corrugated wires are preferably two in number, as shown in Fig. 1 of the drawings, but more may be used, if desired. By the above described construction, 1n which longitudinal wires provided with loops are supported only at their ends and a few intermediate points, with unconnected loops between the supportin points, the bed will conform readily to the orm of the occupant. This is owing to the fact that the unconnected loo s between the supports can be depresse below the supported 1Lpoints of the fabric, while in all other wireabrio beds of which I am aware if any two oints in the length of the bed-bottom are epressed the portion of the fabric between said points will extend in a straight line. In forming the bed-bottom the wires 27 are placed in position with the loops vertical, as shown in Figs. 3 and 4, and the corrugated wires are passed through the loop and secured to the extreme side wires 27, after which the said wires 27 are twisted to bring the loops in a horizontal position, as shown in Fi 1. The tension of thewires 27 thus holds t e loops 28 firmly in engagement with the corrugations of the Wires 30, and thus prevents any lateral displacement of the wires 27. Y

In Figs. 5 and 6 I have shown a modificai tion which is similar to the bed shown in Fig.

1, eXce t. that in place of the side rails 18 side rais 35 are provided, which are in the same plane as the rails 15, and the side rails 15 are hinged or pivoted at 36, so that the bed may be folded. In order to allow the sides of the bed to be .folded down, the transverse wires 30 are provided with hinges or joints 37. In this form of bed the bottom is supported by any suitable means, such as legs 38, (shown in Fig. 6,) and the sides of the frame may be supported by any suitable means, such as the curved guides 39.

In Fi s. 7, 8, and 9 I have illustrated a form of ed in which the bed is folded transversely in place of longitudinally, as shown in Figs. 5 and 6. In this construction the side rails 35 are provided with hinges or pivots 40, so that the ends of the bed may be folded up, as shown in Fig. 7. The end rails 15 also preferably carry head and foot pieces 41. The ends of the frame may be supported by means of folding feet 42. In this construction in (place of the corrugated wires 30 being jointe or hinged it is necessary to oint or hinge the looped wires 27. This may be done elther as shown in Fi 8 by hinging the parts of the strand 27 on t e transverse wire 30, or it may be done, as shown in Fi 9, by hinging one of the wires 27 to the sai transverse Wire 30 and hinging the other of the wiresto the first-named wire 27 In either case the frame, together with the wire fabric, can fold transversely. In making this form of bed-bottom it is necessary to twist the wires 27 in one direction at one end and in the opposite direction at the other end in order to hold the loops 28 in engagement with the corrugations of the wires 30 by the torsionof the said wires 27, and owing to this the loops Iwill not lie in a horizontal plane, but will be disposed spirally around the wire, as shown in Figs. 8 and 9.

In Figs. 1() and 11 Ihave shown a bed similar to that shown in Fig. 7, in which, however, neither the longitudinal wires 27 nor the cross-wires 30 are ivoted or hinged. In this construction the ongitudinal wires will be bent, as shown in Fig. 11, when the bed is folded up. As the bends, however, are not sharp, the longitudinal wires will not be injured.

My bed-bottom, while very simple in construction and cheaply manufactured, is very durable and has many desirable qualities. Owing to the formation of the curved portions 29 between the loops 28, especially when curved in a direction opposite to the loo as shown in Fig. 10, the bottom will yield to a short distance -with very little resistance; but after these arts have become substantially straightened) and, the loops 28 must be drawn together to allow the wires to yield further the resistanceis very greatly increased. In case the wires 27- become stretched by use it is only necessary to place through the loops 28 some small implement, such as a nail or stiff piece of wire, and partially rotate the same in a vertical plane parallel with the wire. This will stretch the loops 28 apart and take up any slack in the wire. My wire fabric also has a great advantage in folding beds, such as shown in Figs. 5 and 6, as the corrugated transverse wires 30 hold the longitudinal Wires in position so as to form sharp corners where the fabricliis bent and also to hold the vertical Vparts of the fabric after it is folded rigidly in position, so that the said vertical parts act very much in the same manner as would a vertical solid portion.

In Fig. 13 I have shown a still further modification, in which the longitudinal wires 27 are arranged with the loops 28 in a vertical position in place of in a horizontal position, as in structures hereinbefore described. In this construction-in place of using one cross-wire 3() at each point where it is desired to connect the longitudinal wires I use two of the said cross-wires passing through ad'acent loops and connect these cross-wires by links 45, which firmly hold the cross-wires together, and consequently prevent lateral movement of the longitudinal wires. The ends of these cross-wires 30 are hooked around the loops 28 at 46. When the frame of the bed is hinged, as shown in Fig. 13, the

IOO

IIO

cross-wires 30 are separated at the point where the fabric is to bend, and the adjacent strands 27' may either be connected by links 47, as shown in Figs. 13 and 14, or the adjoining cross-wires 30 may be hooked around ghe loops 28 of the same strand, as shown in Fig. 15 I have shown a modification in which the loop 28 in place of being circular is elongated inthe direction of. the Wire. With this construction there is less tendency to bend the loop at its lower portion, and conseuently this construction is used when it is desired to have the strand bear a greater load than is possible with the loop made circular.
