JACOB HAUSER AND JOHN WHITTAKER, OF BOSTON, MASSACHUSETTS.

STEAM AND AIR ENGINE.

SPECIFICATION forming part of Letters Patent No. 89,148, dated January 3, 1893.

Application filed March 24, 1892- Serial No. 426,262- (No model.

Be it known that we, JACOB HAUSER, a citizen of the Republic of Switzerland, and JOHN WHITTAKER, a citizen of the United States, both residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Steam and Air Engines, of which the following is a specification.

This invention relates to engines in which both steam and air are employed simultaneously, and it consists in the construction and auxiliary to the cylinder of the engine which.

transmits the power.

In the accompanying drawings, in which similar letters of reference indicate like parts;

Figure 1 is an elevation illustrating our invention. Fig. 2 is a longitudinal vertical section of the compressor-cylinder.

A represents a driving mechanism or engine placed upon a suitable bed a, and B is the compressor-cylinder set upon the same bed, the Whole constituting a compressor. The outer shell of this cylinder (see Fig. 2) is lettered B and is provided with the air-inlet C, the water induction pipe D provided with the check-valve D, and the outlet E for both water and air. Within the outer shell is an inner shell. or cylinder F provided with the inlet-valves d and g on opposite sides of the piston, and outlet-valves b and e placed on opposite sides of the piston. h is the pistonrod which is driven by theengine A and pro-.

vided with the piston h within the cylinder F. As the piston is vibrated the water and air enter the cylinder-B and pass down by means of the space between the two cylinders and enter the cylinder F through the valves dand g alternately, the water being con-' ducted downward by the partition is. Thence the piston forces the mixed water and air out of the cylinder F through the valves 12 and e alternately into the upper portion of the space between the cylinders and out through the port E. Thence the water and air are conducted through the'pipe -1 into the receiver I, thence through the pipe J into the heater L, and thence the expanded a r and steam are conducted through the pipe N, provided with the box N for catching the condensed drippings, into the auxiliary cylinder P provided with an ordinary exhaust P. This cylinder is connected by a pistonrod R with the cylinder S connected with the engine T which transmits the power. The pipe S leads from the cylinder S to the boiler. As will readily be understood, while the wa ter is being converted into steam during its passage from the receiver to the auxiliar cylinder, the air is being quickly expand by heat, and, by means of the piston-rod It, acts as a powerful auxiliary to the steam in running the engine.

Havingthus fully described our invention what we claim and desire to secure by Letters Patent is;

In a device of the character described, the combination of the following elements, v1z., the com pressor-cylinder consisting essentially of the outer shell B provided with the water induction pipe D, air induction opening 0 and outlet E for discharging both water and air, and the inner shell F provided with the inlet-valves d g and outlet-valves b e, said inner shell being adapted to receive a piston, as h, and being connected with the outer shell by the partition is; a receiver, as I, connected
