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 UPS (NYSE: UPS).

With its U-P-S name -- and ticker symbol -- no one should be surprised when the parcel delivery giant "ups" its dividend. UPS is boosting its quarterly disbursements by nearly 10% to $0.57 a share. UPS has more than doubled its rate since 2004, and more than tripled its rate since 1999.

Harley-Davidson (NYSE: HOG) is also revving up. The leading motorcycle maker is improving its payouts by 24%. Harley-Davidson shareholders will now be receiving $0.155 a share every three months. The move pushes the stock's yield to 1.3%.

3M (NYSE: MMM) is keeping its impressive dividend streaking going. Investors may want to scribble on a Post-it that 3M's new quarterly distributions of $0.59 a share is 7% ahead of its previous rate. More importantly, 3M has now jacked up its payouts for 54 consecutive years.

Finally, we have Western Union (NYSE: WU) showing investors the money. The global payment services behemoth is giving its quarterly disbursements a 25% upgrade to $0.10 a share. It's not the only way that Western Union is returning money to its shareowners. The company also repurchased $800 million worth of stock last year.
