SPRING BED-BOTTOM.

SPECIFICATION forming 50 at whom, it may concern;

Be it known that 'I, JOHN MOILHONE, of St. Louis, in the county of St. Louis and State of Missouri, have invented a new and Improved Spring Bed-Bottom, of which the following is a full, clear, and exact description. The object of my invention is to provide an improved spring bed-bottom of simple and durable construction, and one combining a high degree of elasticity with a large surface support for the mattress, while allowing it to yield freely to the movements of the body.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a plan view of a portion of a bed-bottom embodying my improvements, and Fig. 2 is a sectional elevation of the same on the line 00 as, Fig. 1.

On any suitable base or frame of crossed or parallel bars or slats a, of the desired length, width, material, and strength, I attach by rivets or bend of the wires, or otherwise, the springs b, which I prefer to make in spiral conical shape, and secure them by their apices to the frame a, as shown. The main tie or lock of thesprings b consists of a bent wire, which may be of U form, or with rounded head or cross-bar; but I prefer to make the ties with side pieces or arms, 0, and a cross head or bar, d, bent horizontally rather sharply at the corners or angles 6, to form abetterlock with the loops or eyes of the springs to which the arms 0 connect, and of the springs with each other, the arms a being also quite sharply bent at about right angles with their plane, to carry the head (2 upward or downward therefrom about the thickness of the material of the wire, as will appear from Fig. 2. The free ends of tie-arms 0 may connect with the tops of the springs in any suitable manner, to have the c'rossheads d work freely in loops connected with thenext springs; but I have arranged the springs to make them in pairs, coiling each spring of a pair from opposite ends of the same wire and bending the middle of the wire to form the tie 0 cl, and also the close elongated loops f, in which loopsthe arms 0 of successive pairs of springs are passed,

and preferably before the last added pair of.

springs are secured at their apices to the. frame-slats a, which latter connection is made bility in use.

when the cross-head d of the tie is drawn quite to the ends of the loops f, as shown in Fig. 1. The arms 0 of the ties may vary in length, as desired, for arranging the springs closer together or farther apart one way of the bed, and the cross-heads (Z may also vary in length for spacing the springs the other way of the bed, the construction being thus adapted to different-sized beds and the degree of elasticity desired in a givensizeby arranging thesprings accordingly. I connect the springs between the ties c d by angular spring-wire ties 9,.which are preferably looped or bent-at the ends over connection of the ties with the springs, which compels the springs to mutually support each other, and leaves them free to return to normal position when the pressure is removed.

I extend or elongate the loops f more than is needed for the slip of the ties c d on each other, in order to form a more substantial rest or support for the bedding between the springs, and to provide by the loops at the margins of the bed for a better connection of any top edge binding-frame it may be desired to apply to the spring-bottom. I

\Vith this construction, arrangement, and combination of the parts, great elasticity of the bed-bottom is secured and maintained, and the parts may easily and cheaply be made and assembled, and are well calculated for dura- 9 I am aware that it is not new to make two springs of one piece of wire, the connecting portion being to form three loops, and to con nect the pairs by a double hook connected by a spring-loop; but

What I do claim as new and of my invention is- A one-piece bedbottom spring consisting of two conical coils', b b, and a tie formed of the elongated loops f f, the arms 0 c, bent ate, and Io the cross-head d, as shown and described.
