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 these past few days.

We can start with Pall (NYSE: PLL) standing tall.

The filtration specialist is boosting its quarterly rate 19% to $0.25 a share. Investors should be used to this by now. Pall has now come through with nine increases since 2004.

Lockheed Martin (LMT 1.71%) is also arming its shareholders with more money. The military contractor's firing up its dividend 15% to $0.15 a share every three months. If Pall's streak of hikes is impressive, you'll appreciate that Lockheed Martin has come through with ten consecutive years of double digit increases.

AZZ (AZZ -0.90%) is also on the move. The maker of specialty electrical equipment is increasing its quarterly disbursements by 12% to $0.14 a share. Why not? The announcement came at the same time that AZZ posted blowout quarterly results and raised its guidance. AZZ now expects to earn as much as $2.40 a share this fiscal year. It should have no problem covering its dividend.

Finally, we have Limoneira (LMNR 1.40%) doing what you're supposed to do when life gives you lemons. The harvester of lemons and other fruits is juicing up is quarterly payouts by 20% to $0.0375 a share.
