Breast pump, patent model, 1879. Patented by William Kennish of Philadelphia (U.S. patent 219738), this breast pump consists of a glass receiver with a hanging glass globe to catch the milk, and a rubber bulb to provide suction. The innovation was the addition of an internal valve and a valve at the bottom of the globe in such a way that continued compression and expansion of the large rubber bulb would cause milk to flow out of the valve at the base of the globe.
