Improved Oscillating Engine.
The accompanying illustration represents an improved oscillating engine designed for small boats, elevators, or in other situations where power is required and there is but little room in which to develop it.
The principal improvement is in the valve gear, by which a common slide valve is used, with or without link motion. The motion of the valve is not affected by the oscillating of the cylinder. The valve has lap and lead and can be set to cut off the same as common slide valve engines.
These engines are designed, with a long stroke in proportion with the bore, to reduce friction on moving parts; at the same time those parts are made as large as possible to make them durable.
The engraving is from a photograph of one with 4 inch bore, 16 inch stroke (link motion), which ran 200 revolutions per minute and reversed instantly backwards and forwards, while standing on blocks on the shop floor without bolting down.
These engines are built by the patentee, J. F. Kingsley, Owego, Tioga County, N. Y. |
