To alli whom it may concern:

Be it known that I, DAvID LEONARD, a citizen ofthe United States, residing at St. Louis, 1n the county of Gratiot'and State of Michigan, have invented a new and useful Spring# Bed, of which the following is a specification'.

My Invention relates to improvements in spring beds, and to that general class employ- 1ng a series or body-portion of convolute springs. The objects of my invention are to construct a bed of this class wherein the resiliency of the' several springs composing said body portion are preserved, arev thoroughly braced, whereby only vertical oscillations can take place; wherein the strain is diffused equally over the surfaceof the bed; and, furthermore, to provide a convenient head and foot portion, the same being so constructed as to be resilient so as to afford ease and comfort and so that the head will be slightly elethe bed. Fig. 5 is a detail view to illustrate' the connectionv between the transverse tie- Wires andthe interlocking connection of they VV-shaped wires.

Like numerals lof reference indicate like parts in all the figures of the drawings.

In constructing my bed bottom I employ a series of longitudinal bars 1, in this instance to the extent of three, though more may be employed if desired, and connect the same by a Series of transverse bars 2, which in the present instance serve as slats and surmount the bars 1. All of the slats with the excep-` tion of those at the ends accommodate and support convolute'springs 3 of the ordinary type.

Extending in opposite longitudinal directions fromnthe uppercoils and connecting cach pair of convolute springs 3"are V-shaped nate wire meet and their eyes 5 interlock,

and they meshing with the adjacent V-shaped wires 4 combine therewith to fill in the rectangular space between each set of four coiled springs 4, so that as a'result an entire spring surface is produced, wherein the mattress or bedding is prevented' from sagging between the convolute springs and is thoroughly supported at all points, and any strain at any one point of the bed is diused equally over the neighboring springs; and finally it will be Seen that the convolute springs can only yield in a vertical direction. .The series of end convolute springs 3 are connected by short transverse tie-wires 7 whose ends are bent to form eyes 8 which engage the coils of the springs, and said tie-,wires also pass through the eyes 5 at the angles of the adjacent V-shaped wires 4. Along its outer edge the convolute springs composing the bank are connected by stringin g wires 10, the terminals of which are bent to form eyes for engaging the end springs of the series and are interlaced between these eyes' through thev intermediate springs, being clippedV as at 11 to the central springs of the series.

From the side rails 1 immediately in front and in rear of those transverse bars 2 adjacent to the end bars of the series rise pairs of upwardlyand outwardly'disposed'spring arms 12, the same supporting at their outer ends head and foot rails 13 and 14, respectively, the spring arms supporting the former being disposed above those that support the latter, whereby the head rail is some distance above the body or bank of springs and the foot-rail. The head and foot rails, like the convolute springs, have extending therefrom V-shaped wires 15, the said wires having their ends driven in and secured by staples 16 to the rails 13 and 14 and their angular [portions twisted to forni eyes 17 that yengage with -the adjacent and longitudinally aligning V- IOO Intermediate the series of cross-bars 2 there are secured tothe rails 1 at the sides of the frame staples 21, and longitudinal tie-Wires 22 are secured to the staples at the ends of the series, and between the same are interlaced through those con volute springs located at the sides of the bed-bottom, whereby the same are bracedand are limited in their vertical upward` vibrations. Similar staples 23 are located upon the ends of the rails 1 and alternate with staples 24 located upon the outer edges of the head and foot rails, limiting wires 25 being secured to the staples 23 and between the same extending through the staples 24, whereby the upward movements og the foot and head rails are likewise limite improved bed bottom and it will be seen that I employ in its make up the well known and advantageous convolute spring as the main portion thereof, forming a bank of the latter at such points of the bed as are subject to the greatest amount of strain and weight, and at these points thoroughly bracing the said springs so as to obviate any but a vertical oscillation upon their part; that I have assiduously avoided the formation of any openings v intermediate the springs, wherein it is possible for the mattress supported thereby to sag, become torn, or otherwise injured; that I have provided for a careful and uniform bracing of the entire bank of springs, whereby the strain to which any one or more may be subjected is diffused over the neighboring springs; and finally I have produced a head and foot portion, the former being elevated above the latter and the body portion of the bed and secured to the latter in such manner as to form a convenient support for the bedding and carry out the uniformity of the bottom as a whole and support the head at a point above the feet and body of the occupant.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

It will b e observed that the V-shaped wires cross each other and that each terminal is connected to different springs of the same series, also that the point of interlocking of theV-shaped wires comes between cach pair of springs. Thus every space is bridged and covered up, and a bed-'bottom is provided having great advantages in point of elasticity and equable motion.

This completes the construction of my .Having described my invention, what I claim is- 1. In a bed bottom, the combination with a series of convolute springs, of pairs of oppor sitely disposed V-shaped wires connecting each pairA of convolute springs .and arranged in the space between the springs and terminating at their angles in eyes between the next adjacent pair of springs in longitudinal alignment, and interlocking with the eyes of those wires connected to those springs beyond the next adjacent pair, substantiallyas specifled. Y

2.v In a bed bottom, the combination with a bed frame comprising transverse bars, and a series of convolute springs supported thereon, of pairs of oppositely disposed V-shaped wires connecting each pair of convolute springs and terminating at their angles in eyes between the next adjacent pair of springs in longitudinal alignment and interlocking with the eyes of those wires connected to those springs beyond the next adjacent pair, .and short transverse wires connecting the springs and passed through convenient eyes of the V- shaped wires, substantially as specified.

3. In a bed bottom, the combination with a bed-frame comprising transverse bars, and a series of convolute springs supported thereon, of pairs of oppositely disposed V-shaped wires connecting each pair of convolute springs and terminating at their angles in eyes between the next adjacent pair of springs in longitudinal alignment and interlocking with the eyes of those wires connected to those springs beyond the next adjacent pair, string wires interlaced through the end springs, clipped to the central springs, and bent to engage the corner springs, substantially as specified.

4. In a bed bottom, the combination with a bed frame comprising transverse bars, and a series of convolute springs supported thereon, of pairs of oppositely disposed V-shaped wires connecting each pair of convolute springs and terminating at their angles in eyes between the next adjacent pair of springs in longitudinal alignment and interlocking with the eyes of those wires connected to those springs beyond the next adjacent pair, upwardly and outwardly disposed spring wires rising from. the rails, head and foot rails supported thereby, and V-shaped wires secured and disposed alternately to and from the end springs and head and foot rails and serving to connect the two, substantially as specified. t

5. The combination with the bed frame, the transverse bars and the series of convolute springs arranged on the bars, of the curved spring arms, the transverse head rail arranged in a higher plane than the bank of springs, the V-shaped wires engaging and connecting each pair of convolute springs on those transverse rails nearest the head rail and at their angles bent to form eyes secured to the said rail, a second series of V-shaped wires IOS IZO

arranged intermediate the said connected convolute springs having their terminals secured to the head rail, and V-shaped wires connecting in pairs the convolute springs on that bar adjacent toV those on the end bar and at their angles bent to form eyes engaging those V-shaped springs whose terminals are secured to the head rail, and transverse Wires 'connecting the end springs of the series and passing through the interlocking eyes of those V-shaped wires in line therewith,V substantially `as specified.

6. A tie and cross bridge for springs, consisting of pairs of V-shaped wires 4, oppowith a corresponding eye of an adjacent shaped wire, substantially as described.

7l- A tie and cross-bridge for springs, consisting of pairs of `V-shaped wires 4, oppositelydisposed and crossing each other, and located in the space between every four springs of the series, the ends of the wires connecting the springs of each pair of that series, the apex of each V-shaped wire being formed with an eye which is disposed between the opposite pair of springs and interlocked with the corresponding eye of an adjacent V-shaped wire, and short transverse tie-wires 7 connecting the springs and passingthrough each pair of 'interlocked eyes of the V-shaped wires, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
