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.

Let's start with Comtech (Nasdaq: CMTL). The provider of telecommunications solutions when the terrestrial infrastructure either isn't there or economically feasible is coming through loud and clear with a 10% boost to its rate. Investors will now be receiving $0.275 a share every three months. Comtech has also recently repurchased 1.5 million shares.

Atlantic Tele-Networks (Nasdaq: ATNI) is also reaching out. Like Comtech, the Massachusetts-based company delivers telco connectivity to underserved markets. Atlantic's quarterly distributions are climbing 5% to $0.23 a share. Investors should be used to this by now since Atlantic Tele-Networks has now juiced up its payments for 13 consecutive years.

Accenture (NYSE: ACN) is also feeling more generous. The consulting giant's new semi-annual rate of $0.675 a share is a 50% improvement. Accenture is also kicking in with a meaty $5 billion share repurchase authorization, returning money to shareowners from both ends.

Finally, we have Clarcor (NYSE: CLC). The filtration specialist is increasing its quarterly payout by 14% to $0.12 a share. Clarcor has now bumped its rate higher in each of the past 29 years.
