To all whom it may concern: I

Be it known that I, ADOLPH I-I. LIGHTER, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have made an Invention 'Appertaining to Spring Upholstered Cushions; and I do hereby declare the following tobe a full, clean and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use-the same, reference being had to the accompanying drawings, and to the characters of refer ence marked thereon,'which form apart of this specification. a V j My invention has for its object to provide an upholstered unit which can be readily placed in position with or relative to other units and readily removed therefrom. It

particularly has for its object to provide in an upholstered unit a spring frame for upholstering cushions, which may be readily formed, which has a supporting rigid part and wherein the shapeof the upholstered part may be maintained-and the cushion, as a whole, will maintain its designed shape notwithstanding the'ordinary use to which the cushion is subjected. Also by my in vention is provided a means'for readily attaching, or connecting, the upholstering part to the cushion frame,

The invention has for its object other features and advantages which will appear from the following description'and upon the examination of the drawings. a

The invention may be contained in cushioned structures of difi'erent forms. .To illustrate a practical applicationof the invention, I have selected a cushion containing the invention and shall describe ,it hereinafter. The structure selected is illustrated in the accompanying drawing in, which- Figure I is an end View of 'thecushion frame. n Fig. II is a fragmentary front elevation of the cushion" frame shown in Fig. 1, with the upholstery and padding removed 7 connection of the brace, rods to the frame;

, Fig. V is a detail of the'bas'ef frame; and

Fig. VI is a view showings modified arrangement of the braces.

7 1, in Eig. I, denotes the spring'sthat are,

supported on a rigid frame 2. They are connected thereto by any suitable meanssuch as by" striking up -ton'gues thee-"maybe suitable means.

clinched down around the lower coils or turns of the springs. The frame 2 is formed of a plurality of cross-bars 3 having raised central portions 4 that form ribs vfor' purposes of making the crossmembers orba-rs 3 strong and rigid. The cross bars3 are connected together by means of strips 5 of metal. The cross bars 3 may be secured to the strips 5 by spot-weldingor by any other the stripsfiare bound together by the bottom edge wire or rod 6 that. extends'all around the frame of the cushion. The ends of the barsand strlps are rolled over the rod or heavy wire 6 which, aifords a'means for,

readily clinching the bars andstrips in position ands means for readly connecting the bars and strips to the marginal wire 6.

i The cushion shown in the drawing is particularly designed for the back of an automobile upholstered seat. The top side or edge of the cushion is provided witha bar or large wire S that extends the lengthof the cushion and its ends 9 are turned inward near the ends of the cushion. A plurality of wires let extend from theupper strip to the. wire 8. Theyare secured by means of clips 15 to the wire 8 and. by means ofthe strips 16 to the strips 5, The strips'16 are secured to" the strips 5 bymeans of suitable rivets or by spot-welding. The strips 15 and the clips 15 form pivotal connections for the stay wires 14. hen, then. the upper edge of the cushion is pressed, the wires 14 extending from the .wire. 8 to the frame operate to push the wire 8 upwards and outwards and carry with it the cushioning material and thus prevent the cushioning material The ends of the bars 33nd i from sagging between the base marginal upwards."

w a The top 'marginal wire 17 is secured tothe Figs. III and IV are details showing the outside spiral springs 1' by meansg of, suitable ed to the rigid parrot theframe means of stay wires 18 and 19 which are conne'etedto the stripsf5 by means of the strips 16 and 20. "Thefstay'wires as" shown in the form illustrated inFig. III cross each other," that -is;, the" stay wires19 areeoaneaed by means asfrhe stri-ps lti and QO to the *upper str ip -5 pressed.

while the stay wires 18 are connected by means of the strips 20 to the lower strip 5. IVhen, therefore, the marginal wire 17 is pressed, the stay wires 18 and 19 will operate to spread the side portions of the marginal wire and thus prevent any of the upholstering cover from becoming so loose that any portion thereof will sag. Brace wire 30 is connected to lower stripy5 and marginal wire 1. by suitable fastening means, such as used for stay wire 14:, and is for the purpose of preventing the. deformation of the marginal wire 17 from being directly communicated to the continuation of marginal wire 17 that functions in the other half of the cushion (not shown). There are preferably only twostay wires30 located in the middle of the cushion. The tendency of the stay wires is to keep the upholstering portion neatly stretched over the top of the cushion notwithstanding any compression that may occur locally-on the cushion.

If desired, the staywircs may extend'fro'm the strips 5 located nearest the sides of the marginal wire17, that is to say, the wires 28' may be connected by 'means'ofthe strips 20 ton strip 5 andthe wires 29 may be connected to a strip 5 as shown in Fig. VI. In other words, the points of connection of'the ends of the wires l8-and 19 may be reversed andtheir ends may be connected'to the ends of'the strip'QO reverse'to that shown in Flg. Q ofthedrawings. In this way, the spreading effect of the wires 18 and 19 will be increased so as to stretch the cushion cover when any portion thereof is compressed. This change in connectionof the stay wires 18 and 19 is shown in Fig. VI.

I claim:

'1. In a back cushion, a base, a plurality of springs connected to said base, a top marginal wire extending around the springs, a pair of sets of stay wires connected to the base at points intermediatethe sides thereof and to points along the marginal wire that correspond to the top and bottom of the cushion, the stay wiresof each set' lying in the same plane, each set being connected to a side of the marginal wire opposed to the side of the marginal wire connected to the other set and adapted for spreading the sides 10f the marginal wire and-the upholstery of :the cushion, when said cushionis com- 2.
