`To all whom it may concern:

Be it known that We, EDWARD G. BUDD and JOSEPH A. WoLL, both citizens of the United States, and both residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, haveinvented certain new and useful Improvements in Cushions, of which the following is a specification.

This invention concerns cushions such as are used for the seats and backs of car-seats and the object of the inventionl is to improve the construction of cushions of this type to4 the ends that a structure possessing great strength and which can be manufactured at small cost is obtained. l

Our improved cushion comprises a frame which is formed of sheet-metal frame sections secured together at their ends, springs supported upon this frame and suitable covering material overlying and yieldingly sustained by these springs. tions of the frame preferably consists of two sheet-metal members having coacting flang`es at the edges by which they are secured together and formed to provide an open space between them, and these members are interlocked in such a way that relative movement- .thereof lengthwise of the frame sections is precluded. The covering material of the seat is secured direct-ly to this frame as by sewing or tackingit thereto, holes being provided in the frame for this purpose. In order that the upper edge of the cushion will readily yield to the pressure, lthe frame of the cushion does not extend up to the upper edge, but instead, a thin strip of metal is employed running around the entire upper edge of the cushion. This strip may be sustained in position by securing it to the ends of the flat springs commonly provided extending over and secured to the upper ends of the spiral springs. `To further prevent relative displacement of the parts this strip may be covered with a suitable textile material and the covering of the cushion sewed thereto.

The preferred embodiment of our invention is illustrated in the accompanying drawings, in which Figure 1 is a top view of a cushion broken away and sectioned in part, Fig. 2 is aseotion on line 2 2 of Fig. 1, Fig. 3 is a side Each of the sec-` view of the cushion broken away and sectioned in part, and Fig. 4 is a perspective view of one of the members of a frame section.

Referring to these drawings, the parts of the cushion are supported upon a rectangular metallicV frame consisting of side sections 1 and end sections 2. Each of these sections is formed of two members, the lower member 3 being provided with-flanges 4 at its edges and the upper member 5 with folds 6 coacting-with these flanges to secure the two parts together, the two parts being so formed intermediate their edges that an open space is provided between them, thus giving greater strength to the frame section as a whole. The two members 3 and 5 are interlocked in such a manner that movement thereof one on another lengthwise of the section is prevented; this may be readily effected by indenting the coacting flangesand folds as indicated at 7. The several frame sections may be secured together at their ends in any suitable manner; this is preferably done by providing overlapping portions at the ends as shown in Fig. 1 and collars lying within the frame sections at these points, into the ends of which the material of the overlapping portions is sunk. Extending between the side sections 1 of the frame are a plurality of channeled transverse rails or slats 8 secured at their ends, as by rivets, to the inwardly extending flange on the frame sections, and mounted upon these slats and upon the members of the frame are a plurality of spiral springs 9. Secured upon the upper ends of these springs and extending across the frame are a plurality of flat springs 10, each of which may, if desired, be covered by a strip of textile niaterial to prevent it from cutting the overlying covering. Lying directly above the cushion frame and extending around the -entire upper edge ofthe cushion is a strip 11 of thin flexible sheet-metal which is sustained in position by riveting it to the ends of all of the iiat springs 10. This strip 11 is preferably covered with canvas 12 or other fabric for a purpose hereinafter described.

Overlying the flat springs 10 and the edge strip 11 is a covering which may consist of a piece of heavy felt 13, a covering of coarse fabric 14 usually termed the f first canvas and an outer covering 15. W e will now describe the means which we employ for securlthe covering in position. Before assembling the parts of the frame-sections, we provide in the lower frame-'members 3 a series of openings, as shownat 16, Fig. 4, preferably staggered to avoid weakening the member along this line, -and also we provide a line of openings 17 in the4 vertical flange ofV the frame-sections formed by the outer flan e on the member 3 andthe corresponding fo d in the member 5. When the covering of the cushion is applied thereto, the first canvas 14 isidrawn down tight on all sides of the cushion and is sewed to the vertical flange of the frame through the openings provided therein as indicated at 18. If desired, the felt interposed between `the first canvas and the springs may be of the same size as the first canvas. and may be sewed to the frame in the same operation. .'VVhen this has been done,

the outer covering 15 is drawn down tight .over the first canvas and its edge carried under `the bottoni of the frame.' Tacks19 are then driven through the covering 15 and into the openings 16 in the frame to hold the covering in proper position. These tacks become wedged in the openings in the frame and are held firmly, but if desired provision may be made for turning the ends.v of the tacks over upon the insidegof the frame-section. 'The outer covering 15 of the cushion is often provided with a beadin 20 at the to edge of thecushion and in oriIer to insure all the parts being held in proper relation, we sew this beaded edge to the-first canvas 14 x and felt 13 or the coverin thereof as indicated at 21, and sew the fe t to the covering 12 ofthe flexible metallic strip 11, as indicated at 22. f A seat cushion constructed in this manner Y is of ample strength to withstand the severe usage to which it is subjected and the edge of the cushion as well as the top will yield to pressure; moreover the means described for securing the covering material tothe frame permits of quickly and securely assembling the arts at small expense.

' l aving 'now described our invention, what We claim as new therein and desire to secure by Letters Patent is as follows:

' .1. A rectangular metallic frame consisting .f

i of four frame-sections secured together, at

` their ends and each consisting of a plurality of sheet-metal strips secured together at their edges and bent longitudinally to provide open space between the sides of the section and a flange running lengthwise of the section, said flanges each having a series of o enings therethrough, slats extending across t e frame, spiral springs mounted on the frame, flat springs supported by said spiralsprings, a covering overlying said flat springs and asewing interlacedthrough the covering and the openings in said flanges to secure the fcvering to. the=fraine, substantially as set forth- 2. .In a cushion, a rectangular metallic frame having a flange -at the outer edge thereof substantially perpendicular to the plane of the frame and openings through said flange, springs supported on said frame, a covering overlying said s rings, and a sewing interlaced through sai covering and the openings in the flange of said frame for holdin the ed es of the covering firmly thereto, su stanti ly 'as set forth. 3.
