To all whom it may concern Be it known thatl, /VILLIAMLEWIS, a citizen of the United States, and resident of lltica, in the county of Oneida, in the State of New York, have invented new and useful Improvements in SprmgScats for Cha1rs,. Set-tees, Bed-Couches, 620., ct which the following, taken in connection with the accompanying drawings is a full, clear, and exact description.

This invention relates to certain improvements in spring seats for chairs, settees, bed-couches, and similar upholstered furniture and refers more particularly to the supporting bars for the springs and to the manner of attaching springs thereto.

The main object is to construct a spring support of relatively thin sheet metal capable of carrying the load for which it is intended without bending or sagging and also capable of forming a relatively broad bea ring for the adjacent ends of the springs.

Another object is to enable the springs to be easily and quickly attached and held to its supporting bar against relative shifting movement.

Other objects and uses will be brought out in the following description.

In the drawings-Figures 1 and 2-- are respectively a top plan and a side elevation of one of my improved spring supporting bars and springs mounted thereon. Figs. 3- and l are enlarged horizontal and vertical sectional views taken respectively on lines 33 and l l Fig. 2, a portion of the bar being shown in Fig. 3 to show the manner of attaching the adjacent end of the spring thereto. Figs. -5- and -6- are horizontal and vertical sectional views similar to Figs. 3- and 'lrespectively showing a modified means of attaching the springs to the bars.

Each spring support consists of a thin sheet metal. bar 1 preferably of steel, having relatively short fiat ends 2 disposed in the same horizontal plane and a relatively long intermediate portion 3 depressed some distance below the plane of the ends 2 and parallel therewith, said depressed portion being V-shape in cross section and having its upper longitudinal edges flaring outwardly and spaced some distance apart in the same horizontal plane to form a relatively broad bearing for the adjacent portions of coil springs i Specification of Lette'rslatent.

which are mounted thereon. In this in stance the opposite ends of the depressed V- shape portions 8 of the bar are united to the ends ':2 by integralofis'et portions which are also flat and of the same width and thickness as the ends, said intermediate portion 3- being provided with a series of, in this instance three transverse apertures 6 through both sides just below its outwardly flaring upper edges for receiving the adjacent ends of a corresponding number of springs -4. These springs are preferably conical and arranged with their larger ends uppermost and substantially in the same horizontal plane while the ends of their smaller convolutions are passed through their corresponding apertures 6 in such manner that the next adjacent superposed convolution rests upon the opposite upwardly flaring edges of the l-shape portion 3 of the bar, thus forming a relatively broad four point bearing for each spring. These broad bearings prevent relative rocking movement of the adjacent ends of the springs upon the bars thereby producing a more stable spring seat by preventing displacement of the springs. Furthermore by passing the ends of the lower convolutions through apertures in. the depressed portion -3- of the bar just below the upwardly flaring edges, prevents displacement of the springs lengthwise of the bar and in some instances the extremities of the lower convolutions, after being insorted through their respective apertures, may be bent laterally to form offsets 7- for holding the springs against lateral dis placement.

The description thus far given applies to the construction shown in Figs. 1 to 4: inclusive but in Figs. --5 and 6 I have shown a slightly modified means of attaching the springs consisting in providing the lhape portion of the bar with two transverse apertures 6 for receiving the lower convolution of each spring in which case the lower end of each spring is left helical and is passed through the apertures by turning the spring.

.ln each of these forms of my invention, it will be noted that the convolution of each spring next above that which is passed through the apertures in the bar, rests upon the upper edges of said bar and has a relatively broad four point bearing thereon around the outside of the aperture or apertures to better support the spring against relative rocking movement on the bar.

hat I claim is: In a spring seat, a spring supporting bar having relatively short flat ends and a relatively long straight intermediate portion V- shape in cross section and having its longitudinal edges flaring upwardly and out Wardly and spaced some distance apart, said V-shape portion having transverse openings through opposite sides thereof near its longitudinal edges and coil springs having their lower convolutions passed through said openings and their next adjacent convolutions resting upon the upper longitudinal edges of the V-shape portion of the bar.

In Witness whereof I have hereunto set my hand this 4th day of August, 1914.
