COIL SPRING CONNEC'IER Filed May 21, 1930 LEO WA 0065 INVENTOR ATTORNEY Patented Dec. 1, 1931 UNITED STATES LEO w. LODGE, or BROOKLYN, N. Y.

COIL SPRING CONNECTER Application filed Kay 21, 1930. Serial No. 454,386.

This invention relates to springs as ued for bed bottoms, upholstery, cushions and the like, and more particularly to novel and valuable means for connecting the coils forming the spring frame together in abutting relation whereby to securely hold the coil springs in place without detracting from the cushioning efi'ect thereof.

The primary object of the invention is to provide novel and improved means whereby the abutting coil springs may be connected to each other and also to tie rods or Wires which are arranged to extend tangentially of the upper and lower coils of the individual springs.

Another object of the invention is to provide a novel and efficient clip device,this clip device having means whereby to securely grip the tie rod and other portions which are adapted to securely hold the coils of abutting springs tightly in place between the clip device and the tie wire securing means within the clip.

Still other objects are to simplify and improve the construction of spring frames and the like and to reduce the cost of the manufacture thereof, while at the same time eliminating the disadvantages of prior constructions wherein tie rods have been provided to extend transversely of the coils to the detriment of the efliciency of the spring frame.

Other objects and advantages of the invention will be hereinafter specifically pointed out or will become apparent as the specification proceeds. I

With the above indicated objects in view, the invention resides in certain novel constructions and combinations and arrangements of parts, clearly described in the following specification and fully illustrated in the accompanying drawings, which latter show embodiments of the invention as at present preferred.

In the drawings:

Fig. 1 is a top plan view showing the present coil spring connecter applied to a plurality of coil springs;

Fig. 2 is a longitudinal sectional 'view through the assembled springs shown in Fig. 1, substantially on the line 22 of Fig. 1;

Fig. 3. is a perspective view showing the first step in constructing the clip device forming part of the present invention, preparatory to securing the same to the tie wire;

Fig. 4 is a perspective view illustrating the clip secured to the tie wire; and

Fig. 5 is a perspective detail view illustrating the clip, with tie wire secured thereto, clenched about abutting coils of a pair of coil springs.

As shown in the drawings, a plurality of coil springs 10, 11, 12 and 13, of any suitable number, are adapted to be secured together in abutting relation. For this purpose I provide a novel clip device 14. This clip device, as will be better seenin Fig. 3, initiates as a relatively small metal plate 15 stamped from a suitable sheet of steel or the like. This plate 15 is provided with a pair of tongues 16 which are struck up from slots 17. A tie rod 18 is then placed transversely across the slots 17 and the tongues 16 when thus struck downward serving to tightly wedge the tie rods in place against movement relative to the plate 15.

The side portions 19 and 20 of the plate 15 are then struck upward as seen at 19 in Fig. 4. The tie wire 18 with a suitable series of clip devices applied thereto in spaced relation is then applied to the abutting coils 21 and 22 of the adjacent coil springs 10 and 12, and 11 and 13 respectively, and the upper portions 23 and 24 of the side portions 19 and 20 are then struck downward in meeting relation as seen in Fig. 5, whereby these upper portions 24 and 23 in combination with the side portions 19 and 20, securely hold the upper coils 21 and 22 together between said clip portions and the tongue portions 16 which secure the clip upon the tie rod 18.

The adjacent lower coils 21' of the springs 10 and 11 are secured to. the corresponding lower coils of the abuting springs 12 and 13 respectively, in the same manner.

It will be understood that the tie wires 18 are all arranged parallel to each other and in super-imposed relation, each tie wire being connected tangentially of the coils of the spring members so that no tie wire crosses the coils themselves. Thus the spring is rendered more efficient for its cushioning purposes and the coils are securely joined to each other at two opposite points. The tie wires and clip devices constructed as described provide a very rigid form of securing device for the coil springs so that no additional securing means are required as for instance at the meeting portions 2") which are located in the transverse plane of the coil springs.

The construction of the present clip device enables the clip to exert a strong squeezing pressure transverse to the thickness of the tie wire 18 so that all the parts are tightly clenched together, due to sharp metal edges which dig into other metal surfaces, thus positively prevent-ing any subsequent relative movement between the clips 14 and the tie wires 18.

The herein above described construct-ion admits of considerable modification without departing from the invention; therefore, it is the wish not to be limited to the precise arrangements shown and described, which are as aforesaid, by way of illustration merely. In other words, the scope of protection contemplated is to be taken solely from the appended claims, interpreted as broadly as is consistent with the prior art.

What is claimed as new is:

1. A coil spring assembly including a plurality of coil springs and a connector therefor including a tie rod and a clip device comprising a metal plate having tongue portions struck up from the body of the plate, said tongues adapted to tightly clench a tie rod across the slotted portions of said plate beneath said tongues, said plate including other portions upwardly and inwardly bent to securely clench a pair of coils of a pair of abutting coil springs against said tongues and above said tie rod, whereby said tie rod extends tangentially of said spring coils and said'clip device securely holds said tie rod and coils together against relative dislodge-- ment.

2. A coil spring assembly including a plurality of coil springs and a connecter thereforv including a tie rod and a clip device comprising a metal plate having a tongue portion struck up from the body of the plate, said tongue adapted to tightly clench a tie rod across the slotted portion of said plate beneath said tongue, said plate including opposite side portions andinwardly bent meeting portions, said side portions and meeting portions being adapted to securely clench a pair of coils of a pair of abutting coil springs against said tongue and above said tie rod, whereby said tie rod extends tangentially of said spring coils and said clip device securely holds said tie rod and coils together against relative dislodgement. I

3. A coil spring assembly including a plurality of coil springs and a connecter therefor including a tie rod and a clip device comprising a metal plate having tongue portions struck up from the body of the plate, said tongues adapted to tightly clench a tie rod across the slotted portions of said plate beneath said tongues, said plate including upwardly extending opposite side portions, said opposite side portions including inwardly bent meeting portions substantially parallel with the body portion of said plate, said side portions and meeting portions being adapted to securely clench a pair of coils of a pairof abutting coil springs against said tongues and above said tie rod, whereby said tie rod extends tangentially of said spring coils and said clip device securely holds said tie rod and coils together against relative dislodgement.

4. A coil spring assembly including a plurality of coil springs and a connecter therefor including a tie rod and a clip device comprising a metal plate having a pair of tongue portions struck up from the body of the plate, said tongues adapted to tightly clench a tie rod across the slotted portions of said plate beneath said tongues to prevent relative axial movement thereof, said plate including upwardly extending opposite side portions, said opposite side portions including inwardly bent meeting portions substantially parallel with the body portion of said plate, said side portions and meeting portions being adapted to securely clench a pair of coils of a pair of abutting coil springs against said tongues and above said tie rod, whereby said tie rod extends tangentially of said spring coils and said clip device securely holds said tie rod and coils together against relative dislodgement.

In testimony whereof I hereby aflix my signature.

LEO W. LODGE.
