Dividend checks continue to get fatter in corporate America as more companies jack up their distribution rates.

Readers of the Income Investor newsletter can certainly appreciate that kind of thinking. Let's take a closer look at some of the companies that inched their payouts higher this past week.

We can start with Seadrill (Nasdaq: SDRL). The deep-sea drilling-rig operator juiced up its already meaty dividend after posting strong quarterly results. Seadrill's new quarterly rate of $0.82 a share pushes the stock's yield to 9.2%. Seadrill will also be kicking in with an extra $0.15-a-share distribution.

Seaspan's (NYSE: SSW) distributions also coasted higher. The owner and manager of containerships bumped its quarterly payouts 33% higher to $0.25 a share. The move pumps up the Hong Kong-based shipper's yield to an impressive 6.4%.

Coach (NYSE: COH) is also increasing its disbursements by a third. The handbag maker's new quarterly dividend will be $0.30 a share, well above its earlier rate of $0.225 a share.

Finally, we have Williams (NYSE: WMB) gushing money. The energy infrastructure giant is increasing its quarterly payout by 16% to $0.30 a share. Williams has made it a priority to return more money to its shareholders.
