Paul M. Benjamin CENTRIFUGAL THRUST MOTOR CROSS-REFERENCE TO RELATED APPLICATION This application is a continuation in part of my copending application Ser. No. 836,815, filed June 26, I969, now abandoned.
BACKGROUND OF THE INVENTION This invention relates to a centrifugal thrust motor, and more particularly, to a motor whereby the energy of rotating masses is translated into a force in a direction transverse to the axis of the rotating weights. The force thus generated may be suitably controlled and used to propel a vehicle, or for other suitable purposes.
There have been many attempts to provide a satisfactory motor taking advantage of the fact that shifting weight exerts a force. The harnessing of this force has tended to be somewhat difficult. This invention provides a means for converting this rotational energy into translational energy, and in this manner, it provides a motor of economical construction and utility, and it overcomes several of the disadvantages of internal combustion engines. For example, there are a few moving parts, the fuel cost for the operation of the motor of this invention would be negligible, wear on the moving parts would be also very slight, and atmospheric pollution from the motor would be but a fraction of that caused by internal combustion engines.
Additionally, this invention has the advantage that the direction of force generated may be changed so that the force is exerted in the desired direction. This is of particular utility in a vehicle whereby the force generated could be exerted in the direction that the vehicle is turning.
It is therefore a primary object of this invention to provide a centrifugal thrust motor of simple yet reliable construction.
A further object of this invention is to provide a centrifugal thrust motor wherein a transverse force is generated by means of a plurality of rotating weights.
Still another object of this invention is to provide a centrifugal thrust motor wherein the direction of the force generated may be controlled and positioned in a beneficial manner.
Yet a further object of this invention is to provide a centrifugal thrust motor of relatively few moving parts.
Still another object of this invention isto provide a centrifugal thrust motor capable of generating a force in a reverse mode.
These and other objects and advantages of this invention will become more apparent to those skilled in the art as description proceeds when considered along with the accompanying drawings in which:
FIG. 1 is a top plan view of this invention in a neutral position;

FIG. 5 illustrates one of the weight members used in thisinvention;
FIG. 6 is a sectional view along lines 6-6 of FIG. 2 and viewed in the direction of the arrows;
FIG. 7 is a sectional view along lines 7-7 of FIG. 1 and viewed in the direction of the arrows;
FIG. 8 is a schematic view illustrating the application of two of the motors of this invention in a vehicle; and
FIG. 9 is a schematic view similar to that of FIG. 8, but showing only one of the motors of this invention as could be used in a vehicle.
DESCRIPTION OF THE INVENTION Referring more particularly to FIG. I, of the drawings, there is shown the motor of this invention generally designated I0. Mounted within the housing I0 for rotational movement and transverse shifting, is a shaft I2. The ends of the shaft I2 extend through elongate openings 14 in housing covers 16.
Rigidly secured to shaft 12 is a bracket I8 which supports arms 20 and 22 in such a manner that arms 20 and 22 may reciprocate within bracket 18. Mounted on arm 20 are a plurality of weights 24, and on arm 22 are a plurality of weights 26. On the other end of arm 20 is a weight 28, and on the other end of arm 22, is a weight 30. Weights 24 are supported for rotational movement on an axle 32 which is attached to arm 20, and weights 26 are likewise supported on axle 34. Weights 24 and 26 are substantially equal, and weights 28 and 30 are substantially equal.
Weights 24 and 26 are constrained to rotational and planetary movement only by means of members 36 and 38 which are integrally formed with the housing, and served to define a track 39 for weights 24 and 26.
As best seen in FIGS. 6 and 7, hydraulic cylinders 40 are provided. These cylinders are of ordinary construction and include pistons 42 and piston rods 44. The rods are connected to shaft 12 by means of coupling member 46. Shaft 12 is free to rotate within members 46. Ports 48 and 50 are porvided within cylinders 40 for admission of hydraulic fluid to either side of piston 42. The hydraulic fluid is supplied by any suitable source (not shown).
As best seen in FIGS. 6 and 7, the motor housing 10 is supported by means of journals 52 in such a manner that the housing may be rotated. A ring gear segment 54 is provided on the exterior of housing 10, and a worm gear 56 is in mesh with ring gear segment 54. Thus, rotationof worm gear 56 in a manner to be described later will cause rotation of housing 10.
Means (not shown) are provided for rotating shaft 12, and with it weights 24, 26, 28, and 30. Any suitable means such as a small internal combustion engine, electric motor or hydraulic motor may be used.
Although the invention thus far described has illustrated only two weight support arms, additional arms could be used with appropriate adjustments made to the invention described. Additionally, other weights could be added to arms 20 and 22.
OPERATION The operation of this invention will be described with respect to FIGS. 1, 2 and 3. In FIG. 1, weight 24 is shown to have rotational working length 58, which is equal to working length 60 of weight 26. Weight 28 has a working length 62 which is also equal to working length 64 of weight 30. Therefore, since weights 24 and 26 are equal, and weights 28 and 30 are equal, the force moment defined by weight 24 and working length 58 plus the moment defined by weight 30 and working length 64 is equal to the force moment of weight 26 and working length 60 plus the force moment of weight 28 and working length 62. The motor is said to be in a neutral position when these forces are equal.
When fluid pressure is admitted through ports 50 of hydraulic cylinder 40, pistons 42 are shifted to the right as seen in FIG. 6. This corresponds to the shift in the shaft 12 as seen in FIG. 2 and 6. Since the force generated by the rotating weights is a function of the mass of the weights, the working radius of the weights, and the angular velocity of the weights, and an imbalance of forces is set up in the mode of operation of FIG. 2. This imbalance of forces results in a vibration of the motor, and obviously, the vehicle in which it is mounted. However, by utilizing a suitable one-way clutch mechanism on the vehicle, the reverse force of the motor is braked, while the forward force is permitted to exert itself through the motor and vehicle frame so as to propel the vehicle. Suitable clutches are, for example, those as shown in US. Pat. Nos. 1,094,756 or 978,966 or 1,067,707.
In this manner, continued rotation of the shaft 12 while in the position shown in FIG. 2 will result in an intermittant force in the direction of arrow 66. As the rotational speed of shaft 12 increases, the intermittancy of the force will decrease and will tend to become a more uniform force. Also, by providing additional weights and corresponding arms, the force also would tend to become'more uniform.
With reference to FIGS. 8 and 9, the motor of this invention 10 is shown mounted within a suitable vehicle. The motor could be mounted in a stationary position as most conventional motors are mounted, however, in the preferred embodiment, housing support journals 52 are provided in order that motor 10 may be rotated. Worm gear 56 is connected by suitable linkage (not shown) to the steering mechanism of the vehicle. The connection is such that when the steering wheel is turned to turn the wheels of the vehicle to the left, for example, the motor 10 will also be turned to the left and the force generated by the motor will be in the direction in which the vehicle is aimed. FIG. 8 shows how an additional motor may be mounted in the rear of a vehicle with corresponding steering means for turning the rear wheels and the rear motor in the same direction. FIG. 9 is similar to FIG. 8, but includes only one motor.
It is to be understood that this motor may be adaptable for other uses such as an agitator or vibrator and so adapted to be mounted on a frame suitable for such purposes.
While this invention has been described in connection with different embodiments thereof, it will be understood that it is capable of further modification, and this application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the invention and including such departures from the present disclosure as common within known or customary practice in the art to which the invention pertains, and as may be applied to the essential features hereinbefore set forth and as fall within the scope of the invention or the limits of the appended claims.
