IMPACT-MOTOR.

SPECIFICATION forming part of Letters Patent No. 770,291, dated September 20, 1904.

Application filed July 15 1901. Renewed August 21, 1902. $eria1. No. 120,596. (No model.)

To 0Z7, whom it may concern:

Be it known that I, ERNsT HUBER, a citizen of the United States, and a residentof Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Impact-Motors, of which the following is a specification.

My invention relates to impact turbine-motors, and while in principle it is equally adapted for the utilization of both liquid and gaseous fluids it is especially valuable when used in connection with steam or other gaseous fluids the initial velocity of a jet of which is very high.

As motors of the type referred to have been heretofore constructed ithas been necessary in order to utilize a material portion of the available energy in a jet of steam to either run the motor at an enormously high velocity, as twenty-five thousand or thirty thousand revolutions per minute, or to so combine a series of motors or motor-wheel's that each will utilize a portion of the velocity of the steam. Motors built on either of these principles are necessarily difficult and expensive in construction, and practical efficiency can only be secured in motors which develop great power.

My invention has for an object to provide a turbine-motor by which substantially all of the available energy in a jet or jets of a fluid may be utilized without the necessity of operating the motor at an excessively high speed and without the necessity of compounding a series of motors in order to make the same practically efiicient.

Other objects of my invention are to provide a motor which may be constructed to efiiciently develop small powers as well as great ones, also one which is compact and simple and cheap and which may be constructed to run in either direction with equal etficiency and without an undesirable and expensive duplication of parts.

These and other objects of my invention will more fully appear from the following description.

My invention consists in the novel parts,

improvements, and combinations herein shown and described.

The accompanying drawings, which are referred to herein and form a part hereof, illustrate one embodiment of my invention and serve, in connection with the description herein, to explain the principles thereof and the best mode in which I have contemplated applying those principles.

In the drawings, Figure 1 is a side elevation of a motor constructedin accordance with my invention. Fig. 2 is a longitudinal section of the same, taken on the line 2 2, Fig. 3. Fig. 3 is a transverse section of the same, taken on the line 3 3, Fig. 2. Fig; 4 is an enlarged sectional view more clearly illustrating certain details of the construction, and Fig. 5 is a plan view of a portion of the device shown in Fig. 1.

My invention is based upon the practicallydemonstrated principle that an infinite number of successive infinitely smallimpacts produced by a jet of a gaseous substance at high velocity will under proper conditions represent in the aggregate substantially all of the available energy contained in the jet.

In carrying my invention into effect a wheel is provided having a multiplicity of minute impact-surfaces so combined as to form an annular mass, and means are provided for directing one or more jets of fluid into said mass of impact-surfaces at an oblique angle thereto, said annular mass having a number of impact-surfaces in the direction of the jet or jets.

Referring now to the drawings in detail, 1 represents a suitable casing. 2 represents a wheel, and 3 represents a shaft upon which the wheel is mounted, said shaft being journaled, preferably, by the ball-bearings 4 in the casing 1. In accordance with the embodiment of my invention shown the wheel 2 comprises an inner portion which preferably consists of a single casting having a hub portion 5 and a rim portion 6, upon which the annular mass of impact-surfaces 7, forming the outer portion, is mounted. This mass of impact-surfaces 7 may be formed in any suitable way.

Care should be taken, however, to give the mass of impact-surfaces as great permeability as is consistent with a suitable number of elements and the required strength and rigidity of the structure, the nature of the fluid to be used, and the initial velocity of a jet thereof being taken into consideration. I have found in practice that a mass of impact-surfaces having a suitable number of elements and a suitable degree of permeability may be formed by placing upon the periphery of the wheel a number of layers of a suitable reticulated material. The permeability of the mass is augmented by making the elements forming the impactsurfaces as compared with the spaces between them as small as is consistent with the strength required. It is to be observed that the number of impactsurfaces in a unit of space varies directly with the distance between the successive surfaces in either or both the circumferential or radial directions. With steam the best results have been produced by winding upon the periphery fifteen or twenty, more or less. convolutions of wire screen having a small gage of wire and a mesh of about twelve to the inch. Where wire screen is used, that having the meshes firmly secured together, as by being galvanized after it is woven, is preferable in order to prevent the elements of the mass from becoming oxidized and at the same time to more firmly secure the elements in position.

Provision should be made to prevent any deviation in the flow of fluid from a circumferential direction in the mass of impact-surfaces. This may be accomplished in any suitable way. In accordance with the construction shown the opposite sides of the ring 7 are closed to the lateral passage of fluid by dipping each of them to a suitable depthas say, one-eighth of an inch-in a bath of suitable soft metal, as indicated at 8 in the drawings. This construction further secures the elements of the mass together and prevents the same from being expanded and loosened upon the wheel under the influence of the centrifugul force. The mass or ring 7 may be further secured to the wheel as a whole by means of the flange-rings 9, which are secured to the opposite sides of the rim 6 and are provided near their outer edges with suitable recesses, in which fit projections 10, formed upon the opposite sides of the ring 7, preferably by being formed integrally with the soft metal 8. Where desired, the intermediate portions of the convolutions forming the ring 7 may be secured together at suitable intervals, as by the wire binding 11, (clearly shown in Figs. 2, 4:, and 5,) said binding 11 preferably being arranged in planes at right angles to the axis of the wheel in order to avoid as much as possible the clogging of the active portion of the ring 7. To facilitate the penetration of the fluid to the innermost layer or layers of the ring 7, the periphery 6 of the wheel may be provided with one or more annular grooves 12, which form escape-passages for such of the fluid as may pass through the ring.

The fluid may be directed into the ring 7 by one or more jets, which should have such an angle with relation to the ring as to cause the fluid in the jet to enter the ring and yield the maximum effect. These jets may be formed in any suitable manner.

In accordance with the construction shown a fluid-supply chamber 13 is formed for a portion of the distance around the circumference of the wheel and an exhaust-chamber 14 is formed around a succeeding portion of the circumference of the wheel. A partition is formed between the fluid-supply chamber and the wheel, in which partition a series of jetforming passages 15 are provided. The passages 15 are preferably tapered, so asto make them successively smaller in cross-section as they approach the wheel, and, as shown, they are formed on lines which are substantially tangential to the inner surface of the ring 7. For convenience of construction the partition between the fluid-supply chamber and the wheel is formed of a series of members 16, removably secured to the casing and between the opposing ends of which the passages 15 are formed. The-size and number of the jets 15 may be varied between widelimits; but care should be taken not to place them so closely together that the steam discharged from one passage will interfere with that discharged from another passage, and the combined area of the passages should not be so great, taking into consideration the nature of the fluid being used and the variations in the velocity and the volume of the stream thereof produced by the mass of impact-surfaces, as to create an objectionable back pressure between the jets and the exhaust. In order to prevent the escape of the fluid around the circumference of the wheel, the inner surface of the partition should be brought as close as possible to the surface of the ring 7, and in order to give the fluid suflicient time to expend its velocity upon the impact-surfaces before it reaches the 'exhaust-chamber the last one of the jets 15 should be located at some distance from the beginning of the exhaust-chamber. To this end the last section 17 of the partition is made considerably longer than the other sections. Rings 17 a may be arranged between the partition and the flange-rings 9 to prevent leakage.

With the mass of impact-surfaces constructed in the manner described it will be noted that there will be an equal number of impactsurfaces facing in opposite directions. In order, therefore, to drive the wheel in opposite directions, it is only necessary to provide an additional set'of jet-forming passages pointing in the opposite direction with relation to the circumference of the wheel from that in IOU which the first set 'of jet-forming passages point. This may be conveniently done by providing a second fluid-supply chamber 13 and a second set of partition members 16 17 on the opposite side of the wheel from those before described. In this case the partition member 18, which is located between the fluid-supply chambers 13, has its opposite ends beveled in opposite directions, as shown, and its upper surface is arranged in contact with the wall 19, which separates the chamber 13. The fluid is supplied to the chambers 13 by supply-pipes 20, in which suitable controlling-valves 21 are located. When the motor is being driven in one direction, the fluid-supply chamber 13 which is not in use may, if desired, be made to form a part of the exhaust-chamber, the fluid carried by the mass of impact-surfaces being in this way given more time to free itself. To this end a passage 22 is provided between each of the fluid-supply chambers 13 and the exhaustchambers 14:, said passages being controlled by suitable valves 23. In order to facilitate the operation of reversing the motor, the Valves 21 and 23 may be suitably connected to operate in unison. In accordance with the construction shown these valves are connected to a common operating mechanism which consists of a segment-frame 24, which is pivoted at a central point to a stud 25 and is provided with a pair of segment-arms 26, each of which meshes with gears 27, carried by the valves 23, and with a segment 28, which meshes with gears 29, carried by the valves 21. The segment-frame may be provided with a suitable operating-handle, as 30.

For the purpose of regulating the power of the motor any suitable means may be provided. Preferably, however, the power is regulated by cutting off one or more of the jet-forming passages 15, as in this way they quantity of the fluid discharged into the mass of impact-surfaces is varied without diminish-- ing its velocity. In accordance with the con struction shown a slide valve or gate 31 is arranged in each of the fluid-supply chambers 13. As shown, each of the valves 31 is provided with a series of openings 32, which are adapted to establish communication between the supply-chamber and a corresponding series of the passages 15. As shown, the openings are successively longer from one end of struction shown an ordinary form of centrifugal governor 33 is provlded, the same being driven from the main shaft 3 of the motor by any suitable means, as the bevel-gears 34. The governor 33 is connected to one arm of the angle-lever 35, the opposite arm of which is connected to a bar 36, mounted to slide horizontally in suitable bearings 37 near the top of the casing. The bar 36 is provided at each end with a rack, each of which is adapted to drive a pinion 38, said pinions being mounted on the short transverse shafts 39, which extend through the casing 2 and are provided at opposite sides of the fluid-supply chambers.
