The machine further providing support for a crowned screen media without using a crowned cross-member by providing stringers with differing vertical heights with the centermost stringer having the most height above a flat top cross-member. A plurality of crown straps coupled to a top surface of a cross-member, where the crown straps have a C-shaped portion at one end which has a portion thereof coupled to a top surface of a cross-member. ## Claims ### Claim 1 A vibrating screen system comprising: a pair of spaced apart parallel longitudinal side members; a plurality of cross-members having opposing ends, each of which are coupled to one of said pair of spaced apart parallel longitudinal side members; where each of said plurality of cross-members include sloped end portions; a screen media secured above said plurality of cross-members, which screen media is configured to only allow particles having smaller size than a predetermined size to pass therethrough; a cap plate which is disposed on said sloped end portions; and a plurality of spaced apart stringers which are made with different vertical height characteristics so as to provide support for said screen media in a crowned configuration. ### Claim 2 (depends on 1) The vibrating screen system of claim 1 wherein said different vertical height characteristics are arranged on a central flat portion so that smaller ones of said different vertical height characteristics are proximal to said sloped end portions. ### Claim 3 (depends on 2) The vibrating system of claim 2 further comprising a plurality of crown straps each disposed above and in registration with one of said plurality of cross-members. ### Claim 4 (depends on 3) The vibrating system of claim 3 wherein each of said plurality of crown straps is coupled to a top surface of one of said plurality of cross-members. ### Claim 5 (depends on 4) The vibrating system of claim 4 wherein each of said plurality of crown straps has a C-shaped end which is welded to a top surface of one of said plurality of cross-members. ### Claim 6 (depends on 5) The vibrating system of claim 5 wherein each of said plurality of crown straps has two C-shaped ends each of which is welded to a top surface of one of said plurality of cross-members. ### Claim 7 A vibrating screen system comprising: a pair of spaced apart parallel longitudinal side members; a plurality of cross-members having opposing ends, each of which are coupled to one of said pair of spaced apart parallel longitudinal side members; and a plurality of crown straps each disposed above and in registration with one of said plurality of cross-members. ### Claim 8 (depends on 7) The vibrating system of claim 7 wherein each of said plurality of crown straps is coupled to a top surface of one of said plurality of cross-members. ### Claim 9 (depends on 8) The vibrating system of claim 8 wherein each of said plurality of crown straps has a C-shaped end which is welded to a top surface of one of said plurality of cross-members. ### Claim 10 (depends on 9) The vibrating system of claim 9 wherein each of said plurality of crown straps has two C-shaped ends, each of which is welded to a top surface of one of said plurality of cross-members. ### Claim 11 (depends on 10) The vibrating system of claim 10 further comprising: a screen media secured above said plurality of cross-members, which screen media is configured to only allow particles having smaller size than a predetermined size to pass therethrough; and wherein each of said plurality of cross-members comprises a central flat portion. ### Claim 12 (depends on 11) The vibrating system of claim 11 further comprising: a plurality of spaced apart stringers disposed on said central flat portion; wherein said plurality of spaced apart stringers are made with different vertical height characteristics so as to provide support for said screen media in a crowned configuration; and wherein said different vertical height characteristics are arranged on said central flat portion so that smaller ones of said different vertical height characteristics are proximal to outside end portions of said plurality of cross-members. ### Claim 13 A vibrating screen system comprising: a pair of spaced apart parallel longitudinal side members; a plurality of cross-members having opposing ends, each of which are coupled to one of said pair of spaced apart parallel longitudinal side members; a screen media secured above said plurality of cross-members, which screen media is configured to only allow particles having smaller size than a predetermined size to pass therethrough; and a plurality of spaced apart stringers which are made with different vertical height characteristics so as to provide support for said screen media in a crowned configuration. ### Claim 14 (depends on 13) The vibrating screen system of claim 13 wherein said different vertical height characteristics are arranged on a central flat portion. ### Claim 15 (depends on 14) The vibrating system of claim 14 further comprising a plurality of crown straps each disposed above and in registration with one of said plurality of cross-members. ### Claim 16 (depends on 15) The vibrating system of claim 15 wherein each of said plurality of crown straps is coupled to a top surface of one of said plurality of cross-members. ### Claim 17 (depends on 16) The vibrating system of claim 16 wherein each of said plurality of crown straps has a C-shaped end which is welded to a top surface of one of said plurality of cross-members. ### Claim 18 (depends on 17) The vibrating system of claim 17 wherein each of said plurality of crown straps has two C-shaped ends each of which is welded to a top surface of one of said plurality of cross-members.
