mFLUlD-VISCOSITY MOTOR OR TURBINE.

SPECIFICATION forming part of Letters Batent'No. 760,776, dated Ma 24, 19o4. Application filed September 9,1903. Serial No. 172,501. (No model.)

To all who/'12 it may concern: I

Be it known that I, BEN J. CAMPBELL, acitizen of the United States,-residing at Danville, Pittsylvania county, Virginia, have invented new and useful Improvements in Fluid-Via cosity Motors or Turbines, of which the following is a specification.

My invention. relates to a reversible fluid on rotating cylinder and left-hand spirals on inner surface of outer or fixed cylinder, or vice versa, by frusta of cones with spirals cut as above, or bydisks with plane surfaces perpendicular to axis of rotation in close working fit,

, on which suitable grooves are cut-eccentrically outward in nearly opposite directions,crossing the radius at anacute angle, preferably about slxty-five degrees, right-hand grooves'cuttmg the radius at any point at about an angle of sixty-five degrees on rotating member and similar left-hand grooves on fixed member, or vice versa. It may now be seen thatfluid under pressure admittedfat any point, as one end of cylinder, cone, or near axis of revolving disks, will tend to flow'through the spirals of grooves to points of lower pressure, making practically two' sheets of fluid flowing in contact in nearly'opposite directions at very great speed relative to each other, inducing between the surfaces a stress which tends to produce relative motion of the parts. To reverse the rotation, it is but necessary to reverse the points of admission and exhaust. Anotheraction ofthe-flow of fluid along the grooves which'augments the viscosity stress between the parts resembles somewhat the impact and reaction of the compound turbine. It is caused bythe fluid tending to flow through the shortest path to pointsof lower pressure,

' of the motor. cut in opposite directions,as right-hand spirals leaving one set of grooves at points where hollows of other grooves cross, impinging at nearly a right angle on grooves on opposite member. Thus an action and reaction is set up, thereby adding materially to thedevelopment of power.

As shown by the accompanying drawings, the preferable form of my invention is the 'slightly-cone-shaped disk revolving between mission and exhaust for each of the elements Referring to the drawings, Figure 1 represents a longitudinal section ofan engine of the reversible compound type, showing the reversing-valve and exhaust-port. Fig. 2 is an end view of the engine, showing a halfsection along the line 0 0 and representation of the grooves on the rotatable and fixed members.

Let 1 1 indicate the rotatable members,

' slightly-conical disks suitably fixed rigidly to shaftQ, as by key 41, with means for longitudinal adjustment, as by annular piece 42,

carrying stud 43, said shaft 2 running in suitable bearings, an'd stuffing-boxes 3 3, carried byend casings 4 5, with collars46 4:7 limiting its thrust; 7 7, the stationary members, conforming in shape to and adapted to inclose between themsaid rotatable members, all of which are inclosed within the end casings 4 5 and cylindrical casing 6; 33, the reversingvalve in position for the normal or direction of motion of greatest power, which serves its purpose as follows: Steam or the actuating fluid enters through the admission-port 27 at 14,

thence'througli the open annular chamber 35 'to central part of motor, thence along the grooves between the fixed and rotatable member into concentric chamber 34:, back to center of wheel on opposite side of rotatable Fig. 3 is a bottom view of the reversing-valve, showing in greaterdetail its demember, into annular chamber 36, then to valve at 16, thence to annular chamber 37 as shown by the arrows, thence through holes 32 and outward on both sides of rotatable member into chamber 39, into valve at 18, thence to center of wheel through holes or ports 19 to all sides of rotatable members in that set. Thus through the motor exhausting at 11 in reverse position the actuating fluid enters through admission-port 27 at 21 into chamber 36, thence through grooves of first unit or member into annular chamber 35, into valve at 22, thence through port shown by dotted lines to 23, into concentric chamber 39, thence toward center, into annular chamber 37, into valve at 24;, thence to 25, thence toward center of third system of units, into annular chamber 38, to valve at 26, thence out at exhaust-port 11. v

13 isshaft of valve in suitable stuffing-box and bearing 12, to which a lever 40 or other suitable means. is attached for turning the valve one half-revolution in reversing.

13 represents packingrings, of suitable metal or other material, which may be used to give longitudinal adjustment to the fixed members. The dotted lines 10 show the manner in which grooves cross each other. 9

shows the right-hand grooves on one sideof the fixed members; 8, the left-hand grooves on adjacent surfaces on rotatable members.

The preferable shape of the groove is semieircularor segmental, though a V-shaped groove could be used.

It is to be noted that the grooves 28 in the fixed members do not extend quite to the end of the grooves 29 of the rotating members, thus imparting to the latter itsremaining energy of motion and the reaction of the exhaust.

It is apparent that the fluid acts on the entire surfaces, there being no retarding-friction, which is so wasteful of energy at speeds of revolution common to the turbine.

In a motor or an .engine where it is not desirablethat it be reversible the'reversingvalve may be dispensed with entirely, thus somewhat simplifying. its construction. this case steam can enter at any point of casing intoannular chamber 35, fiow outwardly betweenthe plates into concentric chamber 3 1, thence'back' to center,-then to center of second wheel and out between the members into chamber 39, which could beprovided at any point or points around with holes allowing it to flow directly into next annular chamber, thus through the engine to suitable exhaust, which may be at any convenient point on casing..

The construction as here outlined shows some axial thrust, which for marine or verti cal engines would be desirable to balance the thrust of the propeller or the weight of shaft, dynamo, 620., but easily admits of construction that is balanced as to axial thrust.

A suitable governor may be attached to shaft 2, regulating the supply of fluid admitted through port 27.

It is apparent that changes from the construction herein disclosed may be made. Therefore I do not wish to be understood as limiting myself to the precise form of construction shown and described, but desire the liberty of making such changes as may fairly come within the'spirit and scope of my invention.
