TIE FOR COIL SPR-II\TG$.

Application filed December 31, 1923. Serial No. 683,602.

To all whom it vim-y] concern:

Be it known that 1, JOHN W. Rionannson, a citizen of the United States, and resident of Strattord, in the county of Fairiield and State of Connecticut, have invented certain new and useful ln'iprovements in Ties for Coil Spings, of which the following is a specification.

This invention relatesto a coil spring provided with a binding wire to prevent distortion during tempering. Coil springs are used in large quantities for tire pressure gages, scales, valves. etc., and it is necessary that such springs be of uniform strength and resiliency.- An object of this invention is to make a tie for separately and uniformly binding each side oi he coil, and more specifically with a single wire in such manner as to keep the binding wires on opposite sides of the coil in their proper spaced relation. a V

Figure 1 of the drawings is a cross section of the wire on a coil spring.

Figure 2 is a section on the line 22 of Figure 1.

The coil spring 10, before being tempered, is bound by'the wire 11 preferably of soft iron to prevent distortion of the spring or any of its convolutions in order to insure uniform strength and resiliency in a number or the springs. The single wire 11 has two portions or binding means, 12 and 13, e3:- tending along opposite sides of the coil and each separately and uniformly binding the spring. As will be seen from Figure 1, the binding wire is made in a single piece having its

end holding portions

14 and 15 bent inwardly to lie against the insideot the coil.

The opposite ends of the

portions

12 and 13 are similarly bent inwardly as shown at 16 and 17. The connecting portion 18 maintains'thc

parts

12 and 13 in their proper spaced relation and prevents the convolutions getting out of shape or

part

12 or 13 slipping with respect to the other part. The wire is of generally W shape. One end o the spring may be bent to form a supporting hook 1.9 as is customary.

Among the advantages of this invention may be included the simplification of construction whereby a. single wire is used in place of the two wires in the prior art. A further advantage resides the use of the connecting part 18 for maintaining the

portions

12 and 13 on opposite sides of the coil in their proper relation and preventing one sliding out of position with respect to the other in the event Off its becoming accidentally loosened. Another advantage is the economy in binding wire since it talies less material to bind the spring according to this invention than under the old way. An other advantage resides in the avoidance of a number of twists in the wire for under this invention only a single bend is made in any portion'of the binding wire.

I claim:

1. The combination with a coil spring, of a binding means on opposite sides thereof. each of said means comprising a longitudinal member extending over both ends of the coil and projecting into the same, and means to preserve the spaced relation of said bindin means.

2. The combination with a coil spring, of a single binding wire extending around the same and having portions thereof inserted into the coil spring from opposite ends.

3. The combination with a coil spring, of

a single binding wire having portions er:- tending along the 001i in different spaced portions thereof and bent over each end oi the coil to retain the spring compr ed.

4-. The combination with a coil sp .g, oi a binding wire having portions extending along opposite sides of the same and another portion bent over an end 01 the coil and connecting said portions on opposite sides of the spring to prevent the same from slipping oil.

5. The combination with a coil spring, ot a binding wire applied thereon in the eral shape of a. W and having the sides oi said W elongated and bent over.

6. The combination with a coil spring, oi multiple spaced binding means extending longitudinally of the spring and having end holding portions bent around each end oi the coil, the bent end holding portions ere tending only part way longitudinally of the coil.

Signed at Bridgeport, in the county o't Fairtield and State of Conn, this 22d day of December, A. D. 1923.
