Not every company is slashing its dividend these days. Some of the market's better performers are easing up on their purse strings and sending more money out to their shareholders. So let's take a closer look at some of the companies that inched their payouts higher this past week.

We can start with Robbins & Myers (NYSE:RBN). The global equipment supplier for the chemical, energy, industrial, and pharmaceutical markets is boosting its quarterly dividend by 6% to $0.0425 a share. This is now the fourth year in a row that Robbins & Myers has upgraded its disbursements.

American Financial Group (NYSE:AFG) is also coming through with a 6% increase in its quarterly payouts. The insurer's new rate is $0.1375 a share.

Banks can be generous, too. The quarterly distributions at Bank of the Ozarks (NASDAQ:OZRK) are rising 8% to $0.14 a share. The move is a welcome surprise, since analysts see the Arkansas-based bank posting lower earnings on Thursday.

Finally, we have Calumet Specialty Products Partners (NASDAQ:CLMT) on the move. The hydrocarbon specialist's new payout of $0.455 a share may be just a marginal uptick from its previous $0.45 quarterly rate, but Calumet is still inching in the right direction.

Some of these moves may not seem like much, but there are plenty of companies that haven't been able to support even their current dividends lately.
