Be it known that I, Oliver Josolyne Ellis, a citizen of England, residing at Dartford, in the county of Kent, England, have invented a new and useful improvement in Air-Refrigerating Apparatus (for which I have made application for a patent in Great Britain, dated April 20, 1885, No. 4,882,) of which the following is a specification.

My invention relates to an arrangement of a steam-cylinder, an air-compressing pump, and a air-expanding cylinder and their valves in combination with coolers and with a condenser and an air and circulating pump, constituting altogether an air-refrigerating apparatus having certain peculiarities in the details of construction and arrangement whereby I secure simplicity consistently with efficiency and economy, as I will explain, referring to the accompanying drawings.
