CUSHION -SPRIN G STRUCTURE.

Specification of Letters Patent.

Patented July 2, 1918.

Application filed February 5, 1918. Serial No. 76,251. Y

'1. '0 all whom it may concern:

Be it known that I, WILLIAM J. KELLY, of Clinton, in the county of Clinton and State of Iowa, have invented certain new and useful Improvements in Cushion-Spring Structures; and 1 do hereby declare that the following is a full, clear, and exact description thereof, which 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 reference numerals marked thereon, which form part of this specification.

My present invention relates to cushion spring structures or structures wherein coiled springs are utilized to give the necessary size, shape and especially resiliency to cushions of various sorts.

Heretofore various means have been adopted to prevent the coiled springs brought to.- gether in such structure from making a nOiSe as the springs worked and particularly means have been sought to prevent such noise and incidentally assist in holding the individual springs in place where no metallic frame work has been used to keep the springs in position. A common form has been 7 to inclose the springs or a string of springs in a pocket or series of'pockets. These various ways of preventing noise and of covering the springs have had serious disadvantages such as ineffectiveness in accomplishing the main purpose sought, lack of durability, interference with the handling, grouping and securing of the springs in the structure and high cost of construction.

To overcome these disadvantages and to produce an improved cushion spring structure is the main purpose of this invention.

A further purpose is to provide a novel, effective, convenient and durable form of protected cushion springs.

A still further purpose is to provide an article of the classdescribed which is very economical in cost of production and which is economical and convenient in handling at its various stages and particularly in grouping into the various shapes and sizes of cushions.

A further purpose is to provide an article of the class described wherein the coil ,springs are covered or protected at all points lock without possibility of making any noise or finding an unprotected surface.

Yet another purpose of my invention is to produce an article of the class described of such construction that the covering over the coil springs may be readily placed thereon by machinery or by relatively simple machine processes instead of requiring individual hand work upon the units of the structure.

Further purposes and advantages of my invention will appear from the specification and claim herein.

Figure 1 shows a perspective view of a cushion seat of a construction embodying my invention, a corner of the cushion covering being broken away to show the arrangement and construction of the coiled springs.

Fig. 2 is a vertical sectional view of two adjacent springs on a larger scale.

Referring to the drawings, it will be seen that my invention is illustrated in connection with a common form of spiral springs 4 having top and bottom coils 5 and 6.respectively substantially parallel with each other and connected by the usual spiral or slanting coils 7. It will be obvious, however, that various other forms of coiled springs may be used besides the cylindrical coils shown in the drawings.

These springs are covered with a layer of loose cotton 8 or other fiber of cushioning or sound-deadening quality. This layer of loose material is held upon the surface of the springs 4 by glue 9 or some other suitable strong durable adhesive. Any convenient form of applying the lue to the surface of the springs 4 may used such as spraying the springs with the glue in liquid form or preferably dipping the springs bodily into liquid glue or other adhesive. Then while the glue or other adhesive is wet or active upon the springs the layerof loose cotton or other fiber 8 is applied to the surfaces of the springs in any desired way. Preferably as shown in the drawings the layer of loose fiber 8 will be applied to every surface. of the springs 4, that is not only to the outside surface where the springs naturally rub against each other when brought together in a cushion and the upper and lower surface of the various coils of the spring where they come together when the individual springs contract or when adjahave the layer of also to the inward facing coils. It will'be obvious that cotton or similar loose material of a fibrous nature-applied to the springs as by glue will be held thereon' not only by the strength of the glue acting upon the immediate particle of material but that the fibers of the material will be glued somewhat to each other about the circumference of the wire of the springs and so help to securely hold the material upon the springs against any abrasive action of the s rings when in action. When loose soundeadening material of less fibrous nature than cottonis used its particles will also more or.

less adhere to each other with-the assistance of the glue about the surface of the wire. It will be seen that in this product ,I have produced an article which effectively covers the entire outer surface of the springs and which adjacent springs can -be placed thereon readily by machine processes and at little expense and with the use of materi ls that are inexpensive.

The coiled springs for use in this struc ture may be secured to each other either in 86 astring as suggested in Fig. 2 or in a more or less regularly arranged mass such as suggestedin Fig. 1 by any suitable means such as clips 10 encircling the nearest portions of and preferably as suggested applied to the upper and lower coils 5 and a 6 so-as to maintain as regular a surface as possible at the top and bottom of the, cushion or other structure being formed. The mass of such springs may be then inclosed within a covering 11 for an ordinary cushion I or used in a variety of ways well known in the art.

What I claim as new and desireto secure by Letters Patent is:

In a cushion spring structure a spiral spring covered with loose fiber held thereon by an adhesive. h In witness whereof I have afiixedmy siga nature, this 25th day of January, 1916.
