JAMES M. COCHRAN, OF GOBER, TEXAS.

WIND-MOTOR.

SPECIFICATION forming part of Letters Patent No. '715,98 5, dated December 16, 1902.

Application filed May 14, 1902. Serial No. 107,305. (No model.) 4

To all whom, it mctyxcorwern:

Be it known that I, JAMES M. COCHRAN, a citizen of the United States, residing at Gober, in the county ofvFann'in and State of Texas, have invented new and useful Improvements in Vind-Motors, of which the following isa specification. l

This invention relates to certain new and usefulimprovements in windrnotors; 'and the l the top platform 3.

object thereof isto provide a new and improved wind-motor which is simple and durable in its construction, very effective and powerful in operation, and constructed in such a manner as to transmit the force of a series of wind-wheels to a common shaft for driving pumps or other machines; and to this end the invention consists of the novel combination and arrangement of parts hereinafter more' specifically described, illustrated in' the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views.

Figure 1 is an elevation of my improved wind-motor. Fig. 2 is a vertical sectional elevation thereof. Fig. 3 is a horizontal section on the line 3 3 of Fig. 2. Fig. 4 is a horizontal section on the line 4:4c of Fig. 2. Fig. 5 is an elevation of the derrick-frame, showing the tailpiece or vane connected thereto. Fig. 6 is a top plan View of the derrick-frame and the tailpiece or vane.

Referring to the drawings by reference-numerals, 1 denotes the base of the supportingframe; the latter consisting of the said base 1 and the inclined standards 2, preferably four in number (only two shown) and which are connected togetherattheir upper end by The standards 2 may bew connected together' and braced by the crosspieces 4, although any form of brace-rods or cross-pieces may be employed, if desired. Mounted upon the platform 3, aswell as being secured thereto, is a plate 5, which pro jects over the platform and is provided with openings to receive the upper end of the guyropes 6. The upper ends of these ropes 6 are secured to the plate 5 in any suitable manner, and the ropes extend to the ground and are secured thereto by means of the pegs 7. By the employment of the guy-ropes G the supporting-frame is securely held at all times in an upright position. Mounted upon the plate '5 is a bolster-block 8, the function of which latter extending into the supporting-frame in a horizontal manner, supportedalso in the bearings 12 and provided with a bevel-gear.

13, which when motion is imparted thereto rotates the machine-shaft, operating thereby the pump or other suitable machine.

Arranged below the base 1 of the supporting-frame is a receptacle or tank 15, which has its bottom formed with a squared recess to receive the squared lower end 16 of the stationary derrick-rod 17, the latter extending from end to end ofthe wind-motor and having its upper end squared, as at 16', and carrying thereon the cap 18, provided with the outwardly-extending arms 19, which are supported by the inclined braces 20, secured in` any suitablemanner to the cap 18. To the arms 19 are connected the upper end of the guy-ropes 21, while the lower ends of these ropes are secured to the ground in any suitable manner, and these ropes are adapted to retain the upper portion of the wind-motor in an upright position.

The reference-numeral 22 denotes the derrick-frame, which is constructed of four or more vertical standards 23, secured at their upper ends to the top plate 24 and at their lower ends connected to diagonally-extending cross-sills 25 26, arranged one above the other, and which are providedfwith a centrally-arranged opening, for the purpose hereinafter described. The cross-sillV 26 has secured to its lower face a circular bearing 27, which operates upon the bolster 8 and is formedl with a centrally-arranged opening registering with he opening of the cross-sill 26.

The reference-numeral 28 denotes a series of vertically-extending inclined brace-rods,

which are connected at their lower ends to the cross-sills 25 and 26 and at their upper ends secured to the standards 23. The sides of the derrick-frame 22 have connected thereto a series of diagonally-extending brace-rods 31, which cross eachother at their center, as shown in Fig. 5. These rods impart strength and rigidity to the frame for the reason that they are secured in any suitable manner to the standards 23. The derrick-frame 22 has secured thereto an upper and lower pair of horizontally-extending supporting-rods 32 33. One rod of each pair is secured to the front and the other rod to the rear of the frame. Each pair of rods is connected together as well as braced apart by means of the diagonally-extending stay-rods 34, which are also arranged in pairs. The rods 32 are connected together at their outer ends by means of the cross-pieces 35, and the rods 33 are connected together at their outer ends by means of the cross-rods 36. Each pair of supporting-rods 32 33 is adapted to support the wind-wheels and gearing for operating the power-shaft, to be hereinafter described.

Mounted upon the derrick-rods 17 and extending to the lower edge of the squared upper end of said rod 17 is the inner power-shaft 37, which is preferably constructed of a hollow pipe and carries near its upper end the bevel-gear 38, adapted to mesh with the bevel-gears 39 40, carried on the inner end of the shafts 41 42, respectively. Secured to the derrick-rod 17 is a series of thimbles 43, suitably spaced apart, which form bearings for the inner power-shaft 37.

The reference-numerals 44, 45, 46, 47, and 48 denote a series of spindles which are supported on the rods 32 by means of the bearings 49, and each of the said spindles, with the exception of the spindle 46, carries on its inner end a bevel-gear 50, adapted to mesh with the bevelgears 5l, mounted upon the shafts 4l 42. The spindle 46 carries a gear 46', which meshes directly with the gear 38.

The shafts 41 42 are supported at their outer ends by means of the bearings 52, carried by the cross-rod 35, and further supported by the bearing-braces 53, arranged between the rods 32, as well as being secured thereto, as at 54.

The reference-numeral 55 denotes a windwheel of any preferred form of construction and which is suitably secured to the spindles 45. The wheel 55 has its blades set at an angle, as shown, so as to rotate the same in the direction of the arrow.

The reference-numeral 56 denotes a windwheel arranged and operating in the same manner as the wheel 55.

The reference-numerals 57, 58, and 59 denote wind-wheels which are secured to the spindles 46, 47, and 48, respectively; but the blades of the said wind-wheels are set at a different angle from that, as shown by the wind-wheels 55 56, so as to cause the operation of the gear 38 in connection with the wheels 55 56 in the direction as indicated by the arrow. l have shown five Wind-wheels carried by the rods 32, and three of the wheels are arranged in advance of the others; but it is evident that as many wheels can be employed having their blades set at such an angle so that the proper meshing of the gears will be obtained to drive the gear 38 in a direction as indicated by the arrow and revolve the inner power-shaft 37, which carries on its lower end a gear 60, meshing with the gear 13 on the machine power-shaft. By this arrangement half of the power of my improved wind-motor is applied through the medium of the inner power-shaft to the machine-shaft.

The reference-numeral 61 denotes bearingplates secured within the derrick-frame 22 to prevent the inner power-shaft from wabbling.

The reference-numeral 62 denotes the outer power-shaft, which surrounds a portion of the inner power-shaft 37 and extends partly in the lower portion of the derrick-frame and also extends through the bar 9, as well as being supported by the collar 9', carried by the outer power-shaft and engaging the said bar. The outer power-shaft carries a gear-wheel 63, adapted to mesh with the gear 13 on the machine-shaft 11. Interposed between the inner and outer power-shafts is a series of bearing-thimbles 67, the latter suitably secured to the inner power-shaft.

The reference-numeral 68 denotes a bevelgear connected to the upper end of the outer power-shaft G2. The latter is adapted to rotate in an opposite direction to that of the inner shaft 37. The gear 68, which rotates in the direction of the arrow, Fig. 4, is adapted to mesh with the gears 69 70, carried by the shaft 7l 72, respectively. The latter are arranged between the rods 32 and are supported by the bearing-braces 73, secured to the inner face of the rods 33, as at 74, and are also supported at their outer ends by the bearings 75, mounted upon the cross-rods 36. The shafts 71 72 carry the bevel-gears 76,which are adapted to mesh with the bevel-gears 77 on the inner ends of the spindles 78, 79, 80, and 81. These spindles are supported in the bearings 82, carried by one of the rods 33.

The reference-numeral 83 denotes a spindle supported in the bearing 84, carried by one of the rods 33, and is provided on its inner end with a gear 85, meshing directly with the gear 68.

The reference-numeral 86 denotes a windwheel of any preferred form of construction and is secured to the spindle 78. The wheel 86 has its blade set at an angle, as shown, so as to rotate the same in the direction of the arrow.

The reference-numeral 87 denotes a windwheel arranged and operating in the same manner as the wheel 86.

The reference-numerals 88 89 90 denote wind-wheels, which are secured to the spindles 83, 80, and 8l,respectively; but the blades thereof are set at a different angle from that IOC IIO

as shown by the wind-wheels 86 87, so as to cause the operation of the gear 68, in conneci tion with the wheels 86 S7, in the direction as indicated by the arrow, Fig. 4. I have shown five wheels carried bythe rods 33, and three of which are arranged in advance of the other two; but it is evident that as many wheels can be employed with their blades set at such an angle so that the proper meshing of the gears will be obtained to drive the gear 68 in the direction as indicated by the arrow in Fig. 4 and revolve the outer shaft 62 in a direction opposite to that of the inner power-shaft 37 and imparting thereby motion to the machine-shaft 11, in connection with the inner power-shaft. By gearing the lower end of the outer shaft 62 in the manner set forth and although the outer shaft revolves in an opposite directionv to that of the inner shaft the machine-shaft will always be rotated in one direction. The outer shaft takes up the other half of the power of the wind-motor and transmits it to the machine-shaft 11, similar to that of the inner power-shaft 37. 1f desirable, instead of providing the wind-motor with two series of Wind-wheels four can be employed; but two of the series should be connected to I the inner power-shaft in the manner set forth and two'should be connected to the outer power-shaft. This could be obtained by increasing the height of the two shafts and snpplying additional gearing. Although such a construction is not shown, it is obvious that the same can be done. If desirable, the bars 32 33 could loe dispensed with and one or'more wheels employed for each of the powershafts-that is to say, one or more near the upper end of the derrick-frame for the inner power-shaft and one or more near the lower end of the derrick-frame for the outer powershaft, the gears upon the spindles carrying the wind-wheels gearing directly with the gears 38 68 of the inner and outer powershafts, respectively. The wind-wheels are connected to their spindles, so that they are both rotated together.

The reference-numeral 91 denotes a tailpiece or vane which is constructed of any suitable material, preferably sheet metal, and it is connected at its edges by means of the cord or wire 92 to a reinforcing-frame consisting of al pair of rods 93 94 of suitable material bent to conform to the shape of the tailpiece. The upper ends of the rods 93 94 eX- tend upon and are secured to the top plate 24 of the derrick-frame, as at 95 96. The lower ends of the rods 93 94 are bent at an angle, as at 97 98, and then bent to embrace the sides of the derrick-frame 22, as at 99 100, and suitably secured to the derrick-frarne by means of the bolts 101. The tailpiece or Vane 91 is also braced and secured to the rods 33 by means of the stay-rods 102, connected at their outer ends to the tailpiece 9 1 and at their inner ends to the said rods. This manner of constructing and `securing the tailpiece in position rigidly connects the same to thederrick-frame, so that 'when the wind strikes the tailpiece the derrick-frame will suitably revolve upon the bearing-piece 27 and around the outer and inner shafts and derrick-rod, owing to the fact that the powershafts extend through the top of the baseframe, bolster, bearing-piece,and cross-pieces 25 26 of the derrick-frame, while the derrickrod extends entirely through the frame and has its upper end, which engages in the cap 18,squared to prevent its turning. Arranged between the lower end of the cap and derrick-frame is a suitable Washer 103. Suitable lnbricating material or water is placed in the tank 15 to prevent the lower end ofthe inner shaft 37 from becoming heated.

The operation of the device is as follows: The wind revolving the wheels 55, 56, 57, 58, and 69 rotates the spindles 44, 45, 46, 47, and 48, the spindles 44, 45, 47, and 48 transmitting motion by means of the meshing of the gears 50 with the gears 51 on the shafts 41 42, the latter rotating the gears 39 and 40, which meshing with the gear 38 will impart motion to the inner power-shaft 37. The gear 46' upon the spindle 46 when it is rotated by the wheel 57 will assist in imparting motion to the gear 38 upon the inner powershaft 37. The latter when rotated will cause the operation of the machine-shaft 11, owing to the meshing of the gear 60, carried by the shaft 37,with the gear 13, carried by the shaft 11. Consequently the power obtained from the upper series of wind-wheels will be transmitted through the medium of the gearing therefor and shaft 37 to the machine-shaft 1l. Simultaneously with the operation of the upper series of wind-wheels the lower series thereof will also be revolved by the wind. The operation of` this lower series is as follows: The wheels 86, 87, 88, 89, and 90 when revolved by the wind will cause the operation of the spindles 78, 79, 80, 81, and 83, the spindles 78, 79, 80, and 81, transmitting motion by means of the meshing of the gears 77, carried on the end of the spindles,with the gears 76, carried by the shafts 71 72. The rotation of the shafts 71 72 will impart motion to the gears 69 70, which meshing, with the gear 68 upon the outer power-shaft will canse the same to revolve in an opposite direction to that of the inner power-shaft. The windwheel 38, revolving the spindle 83, will also assist in imparting motion to the gear 68, owing to the gear 85, carried on the inner end of the spindle 83, meshing with the gear 68. The lower series of wind-wheels are geared to the outer power-shaft 62, so that it will rotate in an Vopposite direction to that of the inner power-shaft 37. Vhen motion is imparted to the outer power-shaft 62, the gearwheel 63, carried on the lower end thereof, meshing with the gear 13 upon the main shaft 11, will transmit the power obtained from the lower series of wind-wheels to the machineshaft, therebyv operating the same. The

outer power-shaft is geared to the machine- IOO IIO

shaft in such a manner as to cause the same to rotate in the saine direction as is given it by the gearing carried by the inner powershaft. The inner and outer shafts are employed, so as to obtain the power from both sets of wind-wheels, and these shafts are made to revolve in opposite directions, so as to balance the torsion or twist of the powershafts, so troublesome in all wind motors. The guy-ropes 6 for the supporting-frame are adapted, as before stated, to retain it in an upright position, and the guy-ropes 2l, secured with the cap, are, as before stated, employed to retain the upper portion of the wind-motor in an upright position. The cap is mounted upon the derrick-rod a suitable distance from the derrick-frame, so that it will not interfere in any manner with the operation, or rather the rotating, of the said frame caused by the tailpiece or vane 91. The cross pieces or braces 34: between the rods 22 33 are employed to suitably keep them apart, as well as to prevent the collapsing thereof, and, furthermore, supporting them, as well as the wind-wheels. The derrick-frame is braced in the manner as set forth to withstand the force of the wind, and it is thought the many advantages of my improved wind-motor for obtaining power from a series of wind-wheels and' transferring the power to a common shaft for operating pumps or other machines can be readily understood from the foregoing description, taken in connection with the accompanying drawings, and it will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.
