Wells seems always using one device to sign the different time and place. In Time Machine, we are let to know how 'machine' brought its character into another dimension of time and place. In 'When The Sleeper Wakes' he uses 'Sleeper' to sign how the past is differed to the future. Both processes of time travelling are based on the vision of future-the idea of utopia- by using one device to make a process of defined ideology of time and place.
