My invention relates to improvements in spring bed bottoms.
The object of my invention is to provide a novel spring bed bottom, which is simple, cheap to make, strong, durable, not likely to get out of order, in which the springs are ield firmly together, which assembles the Jrings with minimum space between them, and which affords a firm support for the margins oi a pad adapted to be mounted thereon, or for fabric enveloping the spring structure.
The novel features of myinvention are hereinafter fully described and claimed.
In the accompanying drawing illustrative of my invention,
Fig. l is a plan view of my improved bed bottom.
Fig. 2 is an end elevation of the same.
Similar characters of reference designate similar parts in the different views.
1 designates spiral springs of the double cone type disposed in longitudinal rows the springs in alternate rows being in transverse alinement with each other and in staggered relation to the springs in the other rows.
The end coils at the top and bottom of each spring 1 are of substantially circular form. The top and bottom coils of one end spring of each row are each provided at the side next to the adjacent end of the bed bottom with a straight transversely extending portion 2 forming chord portion of the coil, as the chord of an arc.
The top and bottom coils of the other end spring of each row are each provided with a peripherally projecting U shaped offset 3, the str h-t transverse portion of which extends ti a iisversely of the bed bottom.
The alternate springs at each end of the bed bottom have chord portions 2 transversely alined with each other, the other springs at said end having offsets 3 transversely alined with each other and with said chord portions 2 at said end.
Transverse helicals l respectively encircle the sets of chord portions 2 and the offsets 3, and by engaging the springs hold them from relative lateral movement.

spring wire.
The springs 1 have their upper and lower coils similarly arranged and formed and connected by helicals in a similar manner, when springs of the double cone type, as shown, are employed. I
Various modifications of my invention, within the scope of the appended claims,
may be made without departing from the spirit of my invention.
What I claim is 1. A bed bottom having parallel longitudinal rows of spiral springs, alternate springs at one end of the bed bottom being transversely alined with each other and in staggered relation to the other springs at said end, said alternate springs having respectively chord portions transversely alined with each other, said other springs having respectively peripherally projecting ohfsets transversely alined with each other and with said chord portions, and a helical encircling said chord portions and said ollsets and engaging and holding said end springs from relative lateral movement.
2. A bed bottom having parallel longitudinal rows of spiral springs, the end springs of each row having respectively at opposite ends of the bed bottom a chord portion and a peripherally projecting offset, alternate rows having their end springs in staggered relation transversely to the end springs of the other rows, the chord portions at one end of the bed bottom being in alternate rows and transversely alined with each other, and the offsets at said end of the bed bottom being transversely alined' with each other and with said chord portions at said end and in alternate relationship thereto, and two helicals respectively encircling the chord portions and offsets at opposite ends of said bed bottom, and engaging and holding the end springs of said rows from relative lateral movement.
3. A bed bottom having parallel longi tudinal rows of spiral springs alternate springs at each end or" the bed bottom having respectively chord portions transversely alined with each other, the other springs at said end having respectively offsets transversely alined with each other and with said chord portions at said end, springs of alternate rows being transversely alined with each other and in staggeredrelation to the springs of the other rows, two helicals respectively encircling the chord portions and offsets at opposite ends of said bed bottom, and longitudinal helicals respectively encircling and engaging the outer sides of the springs of the outer rows and the adjacent sides of adjacent springs in adjacent rows, said two helicals respectively holding said end springs from relative lateral movement, and said other helicals holding said springs from relative longitudinal movement.
In testimony whereof I aflix my signature.
