Be My Valentine

A guy walks into a post office one day to see a middle-aged, balding man standing at the counter methodically placing "Love" stamps on bright pink envelopes with hearts all over them. He then takes out a perfume bottle and starts spraying scent all over them.
His curiosity getting the better of him, he goes up to the balding man and asks him what he is doing. The man says, "I'm sending out 1,000 Valentine cards signed, 'Guess who?'"
"But why?" asks the man.
"I'm a divorce lawyer," the man replies.

Carpet power-loom

In 1869, William and John W. Murkland were issued a patent for their invention of a carpet power-loom (No. 97,106) as "an improvement in power-loom for weaving in-grain carpet" or other figured fabrics. By making several simplifications to reduce complexity of the machinery, their design reduced the number of cams and levers involved in operating the loom. As a result, less power was required to maintain the motion of the machine. Having fewer parts also reduced maintenance and repair costs.
