Combining bridge rectifier outputs for higher combined Voltage

[SkrillBill]

Working on designing a very basic powersupply (4 outputs; 3 fixed 1 variable) out of some voltage regulators.
Supply will be 1Primary/2Secondary transformer. 115-120v@60hz/ 16v on each secondary. Secondaries are each fed into a rectifier. One rectifier will feed the 5 and 12v regulators, but i need the combined output for the 24 and variable. What is the proper way to tie the outputs of the rectifiers together? Here is the schematic (digikey scheme-it):

Thank you
