Secureci to the front membe 1% and t jofthe eiid members 16 of; the wi 'e frame 13 is a truss member 18 and a strut 19. Any simple form me 'eonneefilig means may he employed for fastening the truss member, stm'it and wire frame together, and Ethanvenience I have illustrated metal clips 20 see Fig. 4 which are passed around the members at the place where they meet and elfe bent 1mm ipigiitly thereon to firmly clip the several niembef's togethelz If desired {Pile piii'te maybe Weldefltogether.

Preferably the, truss member 18 comprises a Piece Of wit-e01 'i'odbe t a1; its middle point, a, igito two oblique braces, or truss members 21 and at 'b, jb; (-whioh are PUSH-3S1 iii. e1mediate said middlebend meats ends) the v v ii'e or is iniio othe obliq fie b 'a ces o truss inembefs 22,1;hat r111 "to; t e

Connecting the iiii ddle bend, a, of the biuss member 18 with theffroni member 14; of thewi e flange, is he sis-17 1 1 w ene' ei e bf Sa .efimieze we eeiee M23 1 with the front member 14, and said end portions are secured to the front member 14 and the strut 18 by clips 20. Other clips 20 secure the intermediate bends b, b, of the truss member to the front-frame member 14.

Adjacent the front member 14 and slightly to the rear thereof is a supplemental front frame member 23 which runs parallel with the front frame member 14 and extends to the end frame members 16, where its end portions are bent parallel to said end frame members 16 and are secured thereto by clips 20. Intermediate its ends the frame member 28 is provided with U bends 24 which extend to the front frame member 14 and space said frame member 23 away from the front frame member 14. The U bends 24 of the frame member 23 are secured to the front frame member '14 by clips 20. The front row of springs may be secured to the frame member 23 or to the front frame member 14, depending upon the location of the front row of springs, since it sometimes happens that the front row, instead of being located in position to be secured to the front member 14 is located back of it and for this reason a supplemental front frame member 23 is employed to which the front row of springs may be secured. The overhang occasioned by the front frame member 14 is sometimes required to provide a wire frame of the proper dimensions to fit a cushion of a given size and as the coiled springs are usually made r of a standard size, it sometimes happens that when nested together, as shown in Fig. 1, the front springs do not extend to the extreme front edge of the frame, in which case they are clipped or otherwise fastened to the frame member 23.

It will be observed that the front member 14, of the wire frame is reinforced by the truss-like member whereby it will maintain its straight line effect although subjected to considerable usage. Moreover, the end frame members 16 are braced and thereby prevented from bulging outward or from being drawn inward. Moreover because of the shape of the truss member 18, persons may sit on either side of the middle of the cushion without being annoyed by the presence of any truss member and when the front edge portion of the cushion is depressed, (as it is when being sat upon) there is no bar or rod located behind the front portion of the cushion which would be swung upward and become noticeable to those sitting upon the cushion.

In the modified or alternative form illus trated in Fig. 5 the supplemental front frame member 23 is carried back parallel with the end frame member 16 and secured to the back frame member 15*. The oblique members 22 of the truss are carried over the supplemental frame member 23 and secured to the end frame member 16 by the clips or otherwise and then bent back to the supplemental frame member 23 and secured thereto by clips or otherwise. This arrangement provides for an overhang at each end of the wire frame and also provides for an additional brace at each end of the device.

More or less variation of the exact details of construction is possible without departing from the spirit of this invention; I desire, therefore, not to limit myself to the exact form of the construction shown and described, but intend, in the following claims, to! point out all of the invention disclosed herein.

I claim as new, and desire to secure by Letters Patent:

1. A seat cushion frame comprising a substantially rectangular frame having front, back and two end frame members, a truss member located within the margin of said frame and having oblique end portions running in straight lines from said end frame members to the front frame member and other oblique portions running from the front frame member to a point midway between the end frame members and behind the front frame member, a strut extending from the front frame member to the middle of the truss member, and means for securing together the frame, truss and strut, at the several places where they meet, said oblique portions and strut forming the sole brace connections between the front and end frame members. i

2. A seat cushion frame comprising a substantially rectangular wire frame having front, back and two end frame members, a wire truss-like member located within the margin of the frame and having oblique end portions running in straight lines from the end frame members to the front frame member and other oblique portions running from said front frame member to a point midway between the end frame members and located back of the front frame member, a strut extending between the front frame member and middle portion of the truss-like member, and metal clips secured around the frame, truss member and strut at the places where they meet, said oblique portions and strut forming the sole brace connections between the front and end frame members.

3. A seat cushion frame comprising a substantially rectangular wire frame having front, back and two end frame members, a supplemental frame member extending parallel with the front frame member and secured to said front frame member and to the end frame members, a truss-like member contained within the margin of the frame and having oblique end portions extending in straight lines from the end framemem bers to the front frame member and other oblique portions extending from the front frame member to a point midway between the end frame members and located back of the front frame member, a strut extending between the front frame member and the middle portion of the truss-like member, and metal clips for securing the frame, trusslike member and strut together at the places where they meet, said oblique portions and strut forming the sole brace connections between the front and end frame members.

4. A seat cushion frame comprising a rectangular Wire frame, a truss member composed, throughout, of a single rod having oblique portions extending between the front and ends of the frame, a strut, extending between the front of the frame andtruss, and fastening means for securing together said frame, truss member and strut, said oblique portions and strut forming the sole brace connections between the front and ends of the frame.

5. A seat cushion frame comprising a rectangular Wire frame having front, back and end members, a supplemental frame member paralleling said front and end frame members, and a single piece truss member having oblique portions connected with said front and end frame members, the ends of said truss member connecting said end frame members with said supplemental frame members and bracing said supplemental frame members.
