Compound direct-action condensing engine; double-action steam pump and fire engine; 3-horse engine.
PATENT STEAM PUMPS. to raise in one continuous stream from 3,500 to 100,000 gallons, from 50 to 100 feet, in 10 hours or upwards.
Fig. 1. Constructed for feeding stationary boilers, for 7,000 gallons in 10 hours, and sizes upwards.
Fig. 2. Constructed for feeding marine and locomotive boilers, for 7,000 gallons in 10 hours, and sizes upwards.
Fig. 3. For the above purposes, and also as a water lift, to raise up to 100,000 gallons in 10 hours. Fig. 3, as exhibited, is made double-action as a stationary fire engine, delivering in a perfectly continuous stream 10,000 gallons 125 ft. high per hour. All these modifications have inlet and outlet air-vessels.
Fig. 6. A THREE-HORSE POWER PORTABLE ENGINE, upon an improved vertical-filled boiler of 4 horse-power, constructed of boiler plate welded and riveted, the interior being everywhere accessible by a man-hole for cleaning out. The boiler serves the purpose of foundation entirely.
Fig. 7. The same class of DIRECT-ACTION VERTICAL ENGINE, constructed from 1 to 25 horse-power. All the parts are direct-action and self-contained on one plate, and expansive motion for variable cut-off of steam is advantageously applied herein.
A PATENT HYDRAULIC RECIPROCATING ENGINE used as a motor, from 1 to 60 strokes per minute, for working bellows of organs, stone-sawing, and other reciprocating purposes. Two examples exhibited.
A NOMINAL 12-HORSE POWER HORIZONTAL COMPOUND ENGINE contained on one bed-plate and foundation, with one slide for varied degrees of expansion, working both the high and low pressure cylinder, with the least possible distance for the port steam to traverse, with the freest openings into and out of cylinders, and with the working parts of one engine balancing the other. Condensor and air pump are double-acting in direct action. This engine has no dead centre, and will work at a maximum speed.
Fig. 8. PATENT SELF-ACTING 2-CWT. STEAM HAMMER, without levers, valve motion, or stuffing box and for a variable stroke and intensity of blow.
A model of PATENT WATER CRANE worked by the pressure of Town's water or hydraulic pressure. This pillar crane will swing all round, and is of 3 powers, consuming water in proportion to weight raised only. These cranes are also made of 6 powers. For 3 powers the water is admitted on 1 and 2 and 2 + 1 = 3 area, and for 6 powers the areas are in the ratio of 1, 2, 3, from which any proportion up to 6 can be obtained.
