This is an early 'three boxer' wood telephone, manufactured by Charles Williams, a contract manufacturer of telegraph equipment who helped Alexander Graham Bell produce his early phones. The upper box holds the magneto
for signalling the operator, the lower box holds the (probably liquid) batteries, and the middle-box is the 'Blake transmitter,' the highest tech transmitter available at that time.
