Self- Propelling Machines. – We read in the Bath Gazette that some persons have lately been “astonishing the natives” of Bath, by traversing the streets at no very moderate pace, mounted on three-wheeled machines, that are a great improvement on the velocipede. Some of these vehicles are propelled by the rider rising up and down, by a motion similar to a horse exercise; from which they have obtained the name of “ups-and-downs.” An improvement has been made by a workman in Bath. His machine has three wheels, placed like those of a bath chair. The small front wheel is only used for guiding and it is turned by a handle that passes to the rider A pair of treadles are affixed to the axle-tree of the two larger wheels: by pressing down the treadles a few inches with each foot alternately, the machine is propelled. The rider is seated between the two larger wheels and proceeds with ease at the rate of six miles an hour, and, with exertion, will perform eight miles; it will also ascend slight hills. The inventor lately went on it from Bristol to Bath in an hour and a half. Its motive power is of much simplicity. When the velocipede was in use he invented some important improvements in it.
