SPRING BED-BOTTOM.

Specification of Letters Patent.

Patented July so, 1907.

Application filed June 4,1907. Serial No. 377,210.

To all whom it may concern:

Be it known that HANSON M. FILLYAW and RUFUS B. HUMPHREY, citizens of the United States, residing at Lumberton, in the county of Robeson and State of North Carolina, have invented a new and useful Spring Bed-Bottom, of which the following is a speciiication.

The invention relates to improvements in spring bed bottoms.

The object of the present invention is to improve the construction of spring bed bottoms, more especially the manner of mounting the spring on the supporting frame, and the means for connecting the spring to maintain the same in an upright position, and to provide a spring bed bottom of great strength and durability capable of being easily constructed and adapted to afford the desired resiliency.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacriicing any of the advantages of the invention.

In the drawing:Figure 1 is a plan view of a portion of a spring bed bottom, constructed in accordance with this invention. Fig. 2 is a detail longitudinal sectional view, taken substantially on the line .t,.t of Fig. 1. Fig. 3 is atransverse sectional view, taken substantially on the line yy of Figv 1. Fig. 4 is a detail perspective view of one of the bottom connecting de vices. Fig. 5 is a similar view of one of the top con necting devices.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

The spring bed bottom is provided with inverted conical springs 1., constructed in pairs and arranged in longitudinal and transverse rows, as clearly illustrated in Fig. 1 of the accompanying drawing, and they are mounted upon a supporting frame, which is composed of sections 2, connected at the ends by centrally arranged hinges 3 to permit the bed bottom to fold. The members of each pair of springs are connected at the top at 4, and they are arranged transversely of the bed bottom. The terminals 5 of the wire, of which each set of springs is constructed, are located at the center of the bottoms of the springs, and they are bent downwardly to provide projecting lugs, which are embedded in the bars 6 of the supporting frame The bars 6 are disposed longitudinally of the bed bottom, and are connected with upper and lower end bars 7 and 8. The upper end bars 7 are supported by approximately triangular blocks 9, arranged in pairs at the ends of the hinged sections of the supporting frame, but the latter may be constructed in any other preferred manner, as will be readily understood.

The springs are retained on the bars by means of transverse connecting devices 10, which retain the projecting terminals 5 in engagement with the bars 6. Each connecting device is constructed of a single piece of wire, or other suitable material, and it is disposed transversely of the bed bottom and extends across the lower faces of a pair of the bars 6. The connecting device 10 is provided with upwardly extending arms 11, located at the side edges of the bars 6 and having terminal eyes 12 to receive the bottom coils of the springs at the opposite sides thereof. The bottom connecting devices 10 positively retain the springs in proper position on the bars of the supporting frame.

The springs at the ends of the longitudinal rows are connected with the end bars by longitudinal stays 13, provided at their inner terminals with hooks 14 and having their outer terminals 15 secured to the upper end bars 7. The end bars are provided with inclined perforations through which the outer terminals of the stays 13 are passed, and the ends of the wire are bent around the stays. The outer ends of the longitudinal stays 13 may be secured to the end bars in any other suitable manner.

The springs are connected between the transverse end rows by means of approximately V-shaped stays or connecting devices 16, consisting of short longitudinally disposed sides or members 1.7 and long diagonally arranged sides or members 18. The short longitudinally disposed side or member connects two adjacent springs of the longitudinal rows, and the diago nally arranged side or member extends from one of the springs of the longitudinal row to the diametrically opposite spring of the next longitudinal row. The sides or members 17 and 18 are provided with terminal hooks 19 and 20, which engage thetop coils of the two members of a pair or set of springs, and the V-shaped stay or connecting device is provided at its apex with a hook 21, formed by bending the doubled wire, and adapted to engage the top coil of one of the springs. Each V-shaped stay or connecting device consists of a single piece of wire, or other suitable material, and it is detachably interlocked with the spring. The hooks at the apex and at the outer terminals of the sides or members may, if desired, be partially closed to positively confine the top coil of the springs in them. The stays maintain the springs in an upright position, and at the same time permit them to yield and afford the desired resiliency or cushioning action.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is

1. In a spring bed bottom, the combination with spaced bars, of coiled springs provided at their bottoms with depending projecting terininals embedded in the bars, and a connecting device located beneath the bars and extending across the lower faces of the same and provided at the relative outer edges of the said bars with upwardly extending arms having terminal eyes receiving the bottom coils of the springs, whereby the latter are retained on the bars and are maintained in engagement with the same.

2. In a spring bed bottom, the combination with coiled springs arranged in longitudinal and transverse rows, of intermediate substantially Y-shaped top connecting devices each consisting of a short longitudinally disposed arm connecting two of the springs of a longitudinal row, and a long diagonally arranged arm extending from a spring of one longitudinal row to the diagonally opposite spring of bus with hooks for engaging the top coils of the said springs.

In testimony, that we claim the foregoing as our own, we have hereto atfixed our signature in the presence of two witnesses.
