OF SAME PLAGE.

IMPROVEMENTV IN STEAM-JET PUMPS.

Specification forming part of Letters Patent No. 57,035, dated August 7, 1866.

To all whom it may concern Be it known that I, CHARLES BARNES, of Cincinnati, Hamilton county, State of Ohio, have inveu ted certain new and useful Improvements in ASteam-Jet Water-Pumps; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had tofthe accompanying drawings, making part of this specification. My invention consists in a certain-construction of steamjet pump, in which the steam is made to issue through numerous orifices which collectively form the Asteamjet when in action, the peculiar construction of the pump admitting also of the passage ot' the water in a direct line from supply to dischargethus avoiding abrupt turns incident to the constructions hitherto given to this class of pumps. In the accompanying drawings, Figure 1 is an axial section of a pump embodying my invention. Fig. 2 is a cross-section, and Fig. 3 an exterior view, of the same.

A is the casing, provided with supply and 'discharge pipes B G, the Whole forming a continuous and direct passage for the Water. I) is the steam-jet tube, concentric with the casing A, and connected thereto by short tube E. `The jet-tube D receives steamvthrough a suitable pipe, F, and at the ends is provided with heads G and G', the latter having numerous apertures, d, which collectively form the jet or steam issue.

I have discovered by careful experiment that by the use of the divided jet a great saving ot' steam is effected, and the stream of A steam-jet water-pump constructed substantially as described, with jet-pertorations d and a direct Water-passage, A B C, as set forth, and for the purpose specified.

In testimony of which invention I hereunto set my hand.

, CHAS. BARNES.
