Dividend-paying companies are an oasis in the desert of underperforming stocks. They offer solid payouts today and the promise of capital gains tomorrow. According to a study by Ibbotson, reinvested dividends made up about 40% of total stock returns from 1926 to 2006. In fact, dividend investing is so appealing that superinvestor Warren Buffett has made it a significant component of his portfolio.

When searching for great dividend stocks, it makes a lot of sense to start with companies that have been playing the dividend game the longest. Standard & Poor's has culled the dividend winners from the also-rans in a list it calls the "dividend aristocrats."

Let's examine the top dividend aristocrats by yield in the Capital Goods industry. For context, I've also included their five-year annualized dividend growth rate.
