Specification of Letters Patent.

Patented Mar. 31, 1914.

Application filed August 14, 1911. Serial No. 643,858.

To all whom it may concern Be it known that I, GEORGE J. GENEBACH, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Cushion- Springs, of which the following is a specification.

The present invention relates to cushion,

springs which may be employed in making vehicle seats, couches, beds, chairs and other articles requiring a light and flexible bottom or back portion, and it has among other things to provide a device of its class that will be light, flexible, durable, tasteful in appearance and economical to manufacture.

Another object of the invention is to provide a cushion having a top edge band or border wire and connecting springs formed in such manner that no rough projections and protruding ends will be exposed to injure a cushion or other top that may be affixed thereto.

Another object is to so form the top crossstays that the top of the cushion will present a uniformly even surface without resorting to the use of clips or other protruding rough or uneven attachments.

Another object is to provide means for the seating of springs upon the cross-stays whereby the springs will be prevented from chucking, creaking or being dislodged, and without the employment of clips or other devices to retain the springs on said stays.

Other objects and advantages will hereinafter appear and be more fully described in the following specification, shown in the accompanying drawing and pointed out in the appended claim.

In the drawing the figure represents a perspective view of a corner portion of my improved cushion spring.

In the drawing, A represents a top edge band or border wire, the same being made to conform in shape to the desired outside contour of a cushion and comprising a piece of wire electrically butt-welded to form an endless encircling band.

B represents a bottom supporting frame wire formed and constructed identically like the top edge band aforesaid, the top and bot tom frame wires within the cushion conforming to each other in the same general outline.

Crossing the sections A. and B from the opposite sides, equally spaced cross-stays 1 and 2 are placed, the stay 1 by preference being placed below the top section and against the under side thereof, and the stay 2 above the bottom frame section, as shown, and electrically welded at the contacting intersections. In forming the top and bottom edge wires A and B and also the cross wires 1 and 2, loops 3 are formed by bending the respective parts where the springs are to be located. A preferred mode of forming these loops is to curve the same inwardly on the top and bottom edge frame section and to arrange the loops on the cross stays opposite the loops on the frame sides in the same relative position and on the same plane. Upon these inwardly-disposed loops and between the top and bottom frame sections the springs l are fitted, the end coils of the respective springs being adapted to cross the sides of the loops to which they are electrically welded.

In forming the cross-stays and frame sections with the loops 3 engaging the springs, as aforesaid, there are manifold advantages in securing the springs within the cushion, among which is great rigidity of construction. The peculiar formation of the curved loops 3 and their relation with the end coil of the springs entirely eliminates all tendency to side thrust in the anchorage of the springs and at the same time prevents the springs from either upward or downward movement in their bearings through recoil from sudden jolt and rough usage, rendering the springs of great importance in automobile locomotion where fast driving and rough and uneven roads are to be contended with.

In the formation of a seat or cushion it would be evident that where both top and bottom cross stays are employed the stays on one side thereof could be arranged longitudinally and on the opposite side transverse or crosswise thereof with equally good results. In the construction of a seat or cushion where nothing but the bottom stay wires are employed, the same may be arranged either transverse or longitudinally thereof; in ordinary practice the stays are arranged crosswise of the seat through the narrowest dimension thereof for the purpose of affording a more firm and stable foundation to the respective springs.

From the foregoing description, taken in connection with the drawing, it is believed a more extended description will not be necessary.
