MECHANISM FOR UTILIZING THE POWER OF ENGINES OR MOTORS.

SPECIFICATXON forming part of Letters Patent No. 697,175, dated April 8, 1902.

Application filed July'26. 1901. Serial No. 69,763. (No model.) l

To a/ZZ whom it may concern:

Beit known that l, HENRY lV. SCHLOMANN, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Mechanism for Utilizing the Power of Engines or Motors, of which the following is a specification.

My invention more especially relates to en gines or motors of the class driven by intermittent impulses acting in one direction only; and its object is to increase both the power and the smooth running of such motors; to which end my improvements consistin certain novel combinations and organizations of instrumentalities hereinafter described, and specified in the claims at the end of this speciication.

The accompanying drawings show so much of the apparatus as is necessary to illustrate my invention embodied in a single-acting gasengine.

Figure l is a side elevation; Fig. 2, a plan view, and Fig. 3 a modification.

The drawings show the prime motor 1, adapted for actuating an ordinary dynamo 2, connected by suitable conductors 3 3 with a series of incandescent lights 4.

Fig. 2 shows ordinary fly-wheels 9 9, mounted on a driving-shaft 8, actuated from the prime motor in the usual way. An independent or intermediate auxiliary balance-wheel 5, mounted on a suitable shaft between the driving-shaft and dynamo, is provided with a pulley 7 ,driven from the large pulley 6 on the driving-shaft. The usual preferred speed for this auxiliary balance-wheel is double that of the shaft S; but it can be run with good results at as high a speed as four times that of said shaft, or even faster, if desired. Fig. 3 shows this auxiliary balance-wheel as mounted directly on the shaft of the dynamo 2.

No matter how large or heavy the ily-wheels of ordinary engines may be made they cannot store power so that it can react and be given back to the engine to be transmitted to the load with the same efficiency as can be attained by a balance-wheel running at a higher speed located between the motor and its load or on the shaft carrying the load if such shaft is carried at a higher speed than the crank or driving shaft.

The auxiliary balance-wheel 5 is not necessarily of large diameter, but must be of great weight. The largest possible proportion of such weight is preferably put in its periphery, and its momentum being proportional to its velocity is much greater than that of the ordinary fly-wheel running at the speed of the crank-shaft. This organization reinforces and renders more uniform the motion of the large balance wheel or wheels. The ordinary fly-wheels have neither the impetus, centrifugal force, nor momentum requisite for such work. My im prove ments are adaptable to thermodynamic engines and motors, and especially adaptable to single-acting engines employed for electric lighting, for which purpose smooth uniform running is required.

The tendency of my improved organization is to maintain the full speed of the engine at the moment of the greatest pressure given by the impulse on the piston during its outstroke throughout the succeeding instroke or immediately-following revolutions or until the piston has received another impulse. The greater the number of revolutions the engine or motor makes to an impulse on the piston the greater will be its efficiency.

In the construction of my improved auxiliary balance-wheel the mass of weight should be so proportioned as to give the largest possible eficiency relatively to the character of the work to be done and the relative diameter of all pulleys should be such as to give the required speed for attaining the best efficiency. These details involve only the wellknown skill of the constructor.

The movement of the ordinary single-acting engines or motors as now built is apt to be uneven or irregular, owing to the character of the impulses, and double-acting engines are liable to the same defect in a lesser degrec. Such engines are therefore not well adapted to electric lighting, owing to the flicker or pulsation of the lights caused by this uneven movement. My improvements render the speed uniform and maintain a brilliancy and intensity of such lights with very slight if any change regardless of any class IDO or character of the prime motor employed. The power of the impulses received on the piston is distributed throughout the revolution of the crank and immediately succeeding such impulse and its succeeding revolutions or between the impulse received, thus maintaining a uniform speed, and as all the pressure on the pistons is thus utilized without increased consumption of fuel or gas the efficiency of the motor is largely increased.

Figs. l and 2 show the intermediate or independent auxiliary balance-wheel on an independent or separat-e shaft located between the ordinary balance-wheel shaft and its load and so driven from the driving-shaft as to run at a much higher speed than the engine or motor.

Fig. 3 shows the auxiliary balance-wheel mounted directly .on the shaft carrying the dynamo or load, which construction can only be used when said shaft runs at a considerably higher speed than the engine, which feature of increasedspeed is an essential feature of my invention, for in this manner the impulse or impact given to the piston by the initial and sudden -pressu-re thereon of the steam, compressed air, oil, or gas exploded in the cylinder is transmitted to the high-speed balance-wheel, yby reason of the centrifugal force and momentum of which it reacts on the motor and renders its motion uniform.

What I claim herein as own invention isl. vThe combination of a main fly-wheel, its shaft and an auxiliary balance-Wheel mountnew and as of my ed on a shaft separate from the main fly-Wheel shaft, but driven directly from it vat a higher speed, substantially as and for the purpose set forth.

2. The combination of a main fly-wheel, its shaft and an auxiliary balance-Wheel mounted on a shaft separate from the main Iiy-Wheel shaft, between said fly-wheel shaft and its load, and driven directly from the drivingshaft but at a higher rate of speed, substantially as and for the purpose set forth.

3. The combination substantially as hereinbefore set forth of a prime motor, its driving-shaft, a fly-Wheel thereon, an auxiliary balance wheel having a preponderance of weight in its periphery and mounted on an independent or separate shaft and means for driving said auxiliary balance-wheel at a rate of speed higher than that of the ily-wheel.

4. The combination substantially as hereinbefore set forth of a prime motor, its driving-shaft, a fly-Wheel thereon, an independent or separate shaft, a motor or generator driven therefrom, an auxiliary balance-wheel mounted thereon, and means for driving the auxiliary balance-wheel at a rate of speed higher than that of the fly-Wheel.

lSigned at New York, in the county of New York and State of New York, this 24th day of July, A. D. 1901.

HENRY W. SCHLOMANN.
