ARTHUR M. SOREY, OF OKLAHOMA, OKLAHOMA.

BED-SPRING.

To all whom it may concern:

Be it known that I, ARTHUR M. SoREY, a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Bed- Springs, of which the following is a specification.

My invention relates to steel wire springs, more especially of that type known as the helical bed springs in which a series of them interlocked or attached constitute a support for mattresses and the like; of which the specification follows.

The objects of my invention are; first, to provide a single helical or conical spiral spring which shall substantially retain its place and position when in series supporting a mattress or the like; second, that no wire ends project to contact with the mattress or other matter. I accomplish these objects by the mechanism illustrated in the accompanying drawings, forming a part of this specification, in which:

Figure 1 is a perspective view of one complete spring in place and a portion of another adjacent one showing the method of attaching the upper ends; Fig. 2 is a view in perspective of the lower end of foot of the spring showing its construction and attachment to the supporting wires.

Similar letters refer to similar parts in the several views.

The upper or first convolution of the spring is designated by 1 to complete which the wire is bent inward, as at 2 Fig. 1; the wire is cut forming the stem 4 which is bent outward in line, or nearly in line with the radius of the spring, forming an inwardly extending U which is bent partially around the wire 1 forming the loop-clamp 3 to hold said Wire securely in position. To secure in position the first spring of a series the loop-clamp 3 is extended to form a terminal stem or tying wire 4 which is bent tightly around. the upper frame wire or rod a, as shown at 5 in Fig. 1.

To prepare each spring for tying or locking with the next one of the series the upper wire 1 has a slight downward off-set (6) and the guy-wire 7 has a lateral U- shaped ofi-set 8, and to tie the springs together the stem or tying wire 4 is passed through the loop 8, (which said U-shaped off-set forms in connection with wire 1) and is bent around the first convolution wire Specification of Letters Patent.

Application filed October 11, 1909.

Patented Dec. 6, 1910. Serial No. 522,077.

1 and the guy-wire 7 and has its end pointing downward and toward the preceding spring, see 4 and 4 Fig. 1.

To secure each connected series of springs from lateral movement the guy-Wires extend crosswise and have their ends firmly attached to the upper frame Wire or rod (1, as at 7, Fig. 1.

To secure the foot of each of the series of springs the supporting wires 65 and e have their ends firmly attached to the bottom frame wire or rod Z); the said supporting wires cross each other at right angles, and near their intersections the said wires have slight upward and downward curved bends or off-sets c and cl to form seats for the bottom or foot convolution f of the spring and the intersection cooperating, locking, curved bends or off-sets a forming seats for the supporting wires (Z and c.

The lower end portion of the spring, near its free end or terminal is formed into an upward curved bend or ofi-set f ridin in the seat cl and a greater downward ofi -set f, the object being to prevent the unwinding or other displacement of the lower portion of the spring by the lower convolution f fitting in said off-sets and passing under the wire 6 and over the wire d the foot of the spring is maintained securely in position. See Figs. 1 and 2. The lower end of the spring f is turned upward Within the spring to avoid contacting with other objects.

In assembling, having placed the support ing wires (Z and 6 place the foot or lower convolution f of the spring in its proper place and secure the end of the tie stem 4 to the upper frame wire or rod 64, see Fig. 1. To place the succeeding springs of the series pass the end 4 of the tying or looking stem 4: down through the loop 8 and around the guy-wire 7 and the upper convolution wire 1, as at 4, thus completing the knot securing the top of the springs together after which the lower end or foot of the spring is adjusted by being slightly and temporarily uncoiled and interwoven with the supporting wires cl and e, as shown in Figs. 1 and 2.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is The combination with upper and lower frame-wires, and with intersecting springsupporting wires connected to said lower frame-Wires, said spring-supporting Wires having, at their intersections, cooperating, interlocking, curved bends and, near their intersections, upward and downward curved bends, forming seats, of helical springs, each having a foot portion, comprising a convolution, riding at its intersection with the spring-supporting Wires, in said seats, whereby it is locked against accidental displacement, ,said convolution, near its free end or terminal, having an upward curved bend riding in one of said seats, and a downward bend, forming a lock against unwindmg, sald termlnal being turned upward, the

upper portion of said helical spring having 15 a clamp-loop lockingly engaging a convolution of said spring, said loop-clamp having an extension forming a terminal-tying-stem. In testimony whereof I aflix my signature in presence of two witnesses.
