CARL O. BRAGE, OF ST. JOSEPH, MISSOURI.

SPRING CONSTRUCTION.

Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed April 17, 1908. Serial No. 427,589.

To all wlimn it may concern:

Be it known that I, CARL O. BRAGE, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Spring Construction; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and trated in the accompanying drawings, in

which:

Figure 1 is a top view of said spring construction; Fig. is a sectional elevation of a spring and bands thereon; Fig. 3 is a perspective detail of the end of a band and a coil and edge wire seated in the fingers there of Fig. 4 is a perspective detail of such band,

broken away, showing one of its divided ends or lingers as seen from underneath be fore forming engagement with a coil oredge wire; Fig. 5 is a pers ective detail of a band, broken away at bet 1 ends, showing one of the valleys therein and a section of coil s'eated in said valley, and Fig. 6 is a clip adapted to form engagement with a band over such valley thereby holding the coil spring in position.

Similar letters refer to similar parts in the several views.

In the drawing A- A-are the springs,

B B-a plurality of metal bands arallcl with one another extending from em to end of the device and C (l -are a plurality of cross bands extending parallel with one another from side to side of the device.

I) is an edge wire which is set on a horizontal with the top coils of the springs; The end of bands B B-and cross bands 0 U-are stamped out longitudinally, as shown in Figs. 1, 3 and l, forming at each end digits or fingers F and ll II; the central finger, F, is first bent downward at its shank, at an acute angle, thence horizontally outward, thereby forming a seat f to receive the top coil of an outside spring A; the end of said finger is then bent upward and rearward around the outside and over edge wire D thus forming a c'las f to retain said edge wire and top coil 0 the spring in rigid contact. Fingers H H are each bent upward at their shanks at a corresponding acute angle, thence horizontally outward thus forming opposite seats It It for said top coil, the coil being thus seated from both top and bottom; the ends of said lingers are then bent downward and rearward around the outside and underneath edge wire I), thus forming clasps ll h to assist clasp f in holding the edge wire and coil spring, side by side, in immovable position. At all other points where the bands and to coils intersect, the bands are provided witi valleys forming seats I) b; these valleys are curved to correspond with the curve of-the top coils of the springs which they are adapted to receive. In order to prevent such coils springing out of said.

seats a clip K is provided having bifurcated.

clamp ends k k to clasp underneath the edges of the band at the outsides of the bottom of said seat I): the clip is thus held in rigid position on the band and the coil is held immovable in seat l).

'What I claim and desire to secure by Letters Patent, is 1- In a spring construction the combination with an edge wire, a plurality of spiral springs,

and .metal bands at the tops of said springs and intersecting each other at the center of each spring, of curvedvalleys adapted to receive the top coil of a spring at four opposite points, clips having bifurcated ends adapted to clasp underneath the edges of a band at the conjunction of the sides of the valley and band, to hold said coil of the spring in posi tion, a central linger at each end of each band iliLViDg an acute angle in which to seat from clamping it against the outer side of said coil in an exact horizontal with said coil and bend, substantially as. shownand set forth. 10

In testimony whereof, I afifnr my signature, in presence of two Witnesses.

CARL O. BRAGE. /Yitnesses H. C. VARNER, EVANGELINE O. Gmnows.

beneath the top coil of an outer. spring, the fiiiger tip clamping seid edge wire in position on a line precisely horizontal with the band, and fingers at the sides of said central finger having acute angles to seat .the edge Wire from shove, the finger tips around said wire
