Definitions

• I,GEoRGEW.F1sHEE1NG a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Spring Bed-Bottoms, of which the following is a specication'.
• My invention relates to an improvement in spring bed-bottoms, and relates particularly to those bed-bottoms in which are used double conical spiral springs, and is designed to obviate the necessity of any hook arrangement to connect said springs.
• Figure 1 is a plan view, looking at the top, of a .spring bed-bottom, showing my invention.
• Fig. 2 is a perspective view ol' a small section containing two spirals.
• the slats A, secured to the end blocks, B, constitute thebed-'rame, to which the springs -are secured.
• the springs c of the double spring G are inserted in and stapled to the slats A at the point s.
• the springs b are pressed through the space e of the adjacent spring, so as to interlock the top spire ot' the spring a. with the t'op spire ot the spring b at the point a'.
• the ends of the wire which forms the springs b are inserted in and secured to the slats A at a point distant from the point of insertion s of the spring a equal to the distance across the top or largest spire of said springs.
• each series ot springs are connected with the end blocks, B, by means of a chain or wire,f, interlocking with the said springs, and firmly stapled to top of the end blocks, B.
