Two more dividend aristocrats raised their distributions last week, bringing the total number of raisers in the elite index to 30. This is quite impressive, given the fact that there are almost 5 more months to go before the year is out and that there are only 51 components in it.

Dover Corporation (NYSE: ), manufactures industrial products and components, as well as provides related services and consumables in the United States and internationally, increased its quarterly dividend by 4% to 26 cents per share. Dover Corporation is a dividend aristocrat, which has increased its quarterly dividend in each of the past fifty-four consecutive years. The stock currently yields 2.90%.

Leggett & Platt (NYSE: ), which designs and produces a range of engineered components and products worldwide, increased its quarterly dividend by 4% to 26 cents per share. Leggett & Platt is a dividend aristocrat, which has increased its quarterly dividend in each of the past 38 years. The stock currently yields 5.80%. The company has been unable to cover its dividend payment in 2007 and 2008, so this move is definitely a surprising one from this High-Yield dividend stock at risk. On the positive side, over the past two years the company had a $1.42 and $1.16 in cash flow per share, which still barely leaves any funds for other activities. Another positive fact is that the company has announced that as long as cash flows from operations exceed $300 million, which is enough for capex and distributions, dividends are safe.

Aqua America (NYSE: ), which operates regulated utilities that provide water or wastewater services in the United States, increased its quarterly dividend by 7.4% to 14.50 cents per share.
