TIE FOR UPI-IOLSTERY SPRINGS.

.- Application filed August 30, 1923. Serial No. 660,119.

To all whom it may concern:

Be it known that I, THEODORE HAUSER, a citizen of the United States,residing at Cassopolis, in the county of Cass and State of Michigan, have invented certain new and useful Improvements in Ties for Upholstery Springs, of which the following is a specification.

The invention relates to ties for upholstery springs, and has for its object to provide a device of this character which may be easily and quickly applied toadjacent springs for effectively securing the springs together and at the same time flex with the springs when weight is applied thereon.

Also to provide a tie of this character which will eliminate the use of a separate or independent means for securing the tie to the springs.

A further object is to provide a tie for upholstery springs comprising an elongated strip of metal having spaced U-shaped bends adapted to receive opposite sides of convolutions of the springs, and to be securely clamped on the convolutions by a tool after the tie has been placed in position. The U- shaped bends grip the convolutions and prevent lateral displacement of the springs in relation to the tie.

A further object is to provide an upholstery spring tie formed from a single piece of material provided with portions adapted to grip the convolutions of the springs thereby obviating the use of other securing means for the tie, and at the same time reducing the cost of assembling the springs to a minimum and allowing the tie to be applied by unskilled labor.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is a side elevation of adjacent upholstery springs showing the tie applied thereto.

Figure 2 is a horizontal sectional view taken on line 22 of Figure 1.

Figure 3 is a detail perspective View of a portion of the tie.

Referring to the drawing the numeral 1 designates adjacent upholstery springs of conventional. form, 'which upholstery springs are equally spaced from each other and may be of any number desired according to the type of furniture on which the springs are used. It is now the practice to provide ties wherein separate means, for instance wire, is used to secure the ties to the convolutions 2 of the springs. To obviate this difficulty the ties 3 are provided, which ties are formed from elongated strips of sheet metal which extend across the convolutions 2, and are provided with U-shaped bends 4. spaced apart according to the diameter of the convolutions 2 and the spacing between the springs 1, whereby when the opposite sides of the convolutions 2 are disposed in the U-shaped bends 4, the springs will be in normal spaced relation to each other. After the convolutions 2 have been placed in the bends 41, a clamping tool is applied to the bends 4 adjacent their inner ends, and the U-shaped bends securely clamped on the convolutions 2, thereby positively securing the convolutions 2 and the springs in spaced relation to each other. It will be noted that during the clamping operation, owing to the width of the ties and its grip on the convolutions 2 lateral displacement or movement of the ties is prevented as such movement can occur only by the tie turning as a whole on a center coincident with the center of the springs, which turning movement cannot occur because of the connection of the tie with other springs. The ties 3 have sufficient flexibility to give with the springs when weight is applied thereto, but sufficiently rigid to prevent opening of the clamped U-shaped portions 4 when weight is applied on the springs.

From the above it will be seen that an upholstery spring tie is provided, which will positively hold the springs tied together and that the tie will not become laterally displaced on the convolutions 2. It will also be seen that the use of other means, such for instance as twisted. wire to secure the ties to the convolutions 2 is obviated and that the ties may be quickly applied by unskilled labor and at a minimum cost.

The invention having been set forth what is claimed as new and useful is 1. The combination with adjacent end convolutions of adjacent upholstery springs, of a tie for said springs, said tie comprising an elongated metallicstrip extending across the end convolutions, said metallic strip be ing provided with ofiset bends in: which the opposite sides of the convolutions are received and clamped, said offset bends forming means whereby the strip is secured: to. the convolutions and the strip outwardly spaced from the convolutions" 2. The combination with adjacent end convolutions of adjacent upholstery'springs, of a tie for said springs, said tie comprising an elongated metallic strip extending across the convoluti'ons, said strip being provided with U-shaped bends for the reception; of, opposite' sides of; the conyolutions,

said bends forming means whereby upon aclamping action being applied to the oppo site; sides thereof the convolutions may be securely clamped to the tie and the strip 7 THEODORE HAUSER.
