To all whom it may concern: 7

Be it known that I, FRANK H. HAMPTON, a citizen of the United States of America, and a resident of Pullman, county of Cook, State of Illinois, have invented certain new and useful Improvements in Cushion Edges, of which the following is a specification.

The main objects of this invention are to provide an improved form of cushion edge adapted to form afirm sup ort for the edges of the cushioned surfaces of a spring cushion while at the same time being sufficiently flexible to yield differently at different points when the pressure thereon is unequally distributed; to provide an improved arrangement of the edge pad with respect to the spring structure; to provide an improved form of fastening clip for connecting the edge which clips may be fastened at either strai ht or curved edges of a cushion and may e made of,either wire or flat material; to provide an edge pad and fastening means which require no special base to rest upon, but may be fastened directly to the upper convolution of a coiled spring; and to rovide an improved construction for one ion edge pads whereby the pad will return to its normal shape after distort-ion. These objects are accomplished by the device shown in the accompanying drawings, in which- Figure l is a section, artly broken away,

odying this inveng. 2 is a section taken on the line 2-2 of Fig. 1 and illustrating the edge pad securing means as viewed from the bottom, the edge ad being also artly broken away to show .t e jointed, resi ient reinforcement of the core. Fig. 3 is a corresponding View showing a modified form of the fastening clip and the means for securin it to the s ring frame. Fig. 4 is a side e evation of the parts shown in Fig. 3, the edge pad and cushion bein shown in section, and the line 3-3 indicating the plane from which Fig. 3 is viewed. Fig. 5 is a sectional detail indicating the method of folding and sewing the sheet of canvaswhich forms the casing of the edge pad.

In the form shown .in the drawings, the edge pad consists of a casing 1, re erably of canvas, filled with a stufiing 2 of felt, sawdust, hair, or other yielding material. The casing is preferably formed by folding a sheet of canvas upon itself at 3, as shown in pad ,to the spring structure,

bent to form a part 12 which Fig. 5, and sewing the two parts together at e 4 along a line parallel with the fold 3 and spaced therefrom a suflicient distance to provide an edge pad of the desired diameter when the same is stuffed. The sheet of canvas is of suflicient width to provide comparatively wide flaps 5 and 6.

The spring frame may be of any usual construction. In the form shown in Fig. 1', the frame comprises a plurality of coiled springs 7 of the usual helicoidal shape mounted upon a base 8. The edge pad extends around theotop of the spring frame and is fastened to each of the springs in the outer row by means of a clip 9. The clips 9 are secured to the upper convolution of the correspondin springs and are also fastened to a border p ate 10 which extends along the edge of the frame and is riveted to each of the clips 9, thus serving to bind together the upper ends of the sprin s 7 and also to support the stuffin 11 of t e cushion adjacent to the edge pa The fastening cli s, in the form in which they are shown in igs. 1 and 2, ,consist of single strips of sheet metal. Each strip is encircles the edge pad. At another place it is bent to form a hook 13, which engages the outer part of the upper convolution of the spring and the inner end of the clip, and at its inner end it is split to form the narrow Q'ues 14 which are wrapped around the w. f the upper convolution of the spring. The part 12 of the clip is of such length that its end will engage the seam t'of the casing and hold sald seam at a position close to the top of the spring frame when the flap 5 is pulled tightly over the top of the edge pad and secured to the bottom frame 8.

In assembling a cushionof this form, the clips and border plate 10 are first fastened to the tops of the springs, the hooks l3 and tongues 14 being at this time closed around the wire of the springs so as to firmly hold the clips and border plate in position, the parts 12, however, being left in an open position,,as indicated by the dotted lines in Fig. 1,-so as to permit the insertion of the edge pad. After the edge pad is inserted into position, the parts 12 are bent down to the position shown by full lines by means of a suitable tool. The flap 6 is laid along the upper surface of the frame, and the flap 12 is drawn over the top of the edge pad and tacked or otherwise secured to the bottom of the frame. After the padding 11 is placed in position, it is covered by a sheet of fabric 15 which is sewed to the flap 5 at 16. This is covered by the outer covering of the cushion, not shown in the drawings.

In the modification shown in Figs. 3 and a, the fastening clip 17 is formed of wire in stead of sheet metal, and the hook-shaped bends 18 serve to secure the border wire 19 to the upper convolutions of the spring. In this form the connection between the clip 17 and the spring is reinforced by a second clip 20, and the clip 20 is riveted to the border plate 10 between the two parts of the clip 17 When the clip is formed of wire, it is preferably doubled, as shown, the middle part 21 of the wire being shaped so as to have a broad bearing alon the seam of the pad, (See Figs. 3 and 41% With the form of fastening means which is herein shown, the edge pad is securely held in position while being at the same time free to yield under unequally distributed local pressure which deflects some of the springs 7 more than others. The edge pad is, however, so supported that it always returns to its normal position and maintains the shape of the cushion. As the clips are widely spaced, the edge pad is free to bend between adjacent clips, and it may yield either horizontally or vertically.

In order to insure that the parts of the pad always maintain perfect alinement with each other when not under strain, the core thereof is reinforced by a resilient inner core 22 of metal. This inner core preferably comprises a series of sections or links hinged together, the links being of such length-and being so placed that their joints 23 are adjacent to the clips 9. Thus the edge pad is free to yield with the cushion springs under local pressure, but always assumes its normal shape when the pressure is removed. The links 22 are embedded in the pad material so that they do not come into direct contact with the casing of the pad. In the form shown, the links 22 are each formed from a single piece of resilient wire looped at each end to engage the adjacent links.
