To all whom it may concern:

Be it known that I, HERBERT H. MA C(?M- BER, a citizen of the United States, residlng at Kendallville, Noble county, Indiana, have invented a new and useful Windmotor, of which the following is a specification.

This invention relates to wind motors or windmills.

This invention has utility when embodied,

in features of construction and control of windmills, especially of the vertical or solid wheel type.

' Referring to the drawings: Figure 1 is a.

- ing 80f the upper extremity of the stem 3 into securing relation, thereby maintaining the frame 9'and its stem 3 together as a unit.

The windwheel comprises the central bear-ing or overhanging mounting cone 10 having theconceintric blade mountings 11, 12. Clips 13 on the inner circular mounting 11 engage the blades 1a to positively hold their inner ends, while the embracing members 15 slipped outwardly into snugly fit- Speeification of Letters Iatent.

ting locking relation as to the curved or dished blades 14 fix the angle of pitch of the blades as to the outer circular mounting 12 passing through the blades. The circular mountings 11, 12, are held in position by the radiating arms 16, 17, carried by the cone hub 10. The wheel as described, when built up of metal, may have its resistance to weather deterioration by a coating, as galvanizing. The outer portions of the blades, where the strains are greatest, are securely held by the plate members 15, resisting in their strongest, direction, thereby producing maximum of strength in a light structure and by a devicehaving no connection liable to weather weakening.

The windwheel is fast to the windwheel shaft 18 having secured thereto the pinions 19, 20, intermediate the bearings 21, 22, for the shaft 18 in the frame 9. While the windwheel is overhung, this transmission means from the windwheel shaft is abalancing thereof and a stiff construction in itself. Furthermore, it is to be noted the bearing 21 is long and within the load plane of the blades. The pinion 19 is in mesh with the crank 28 fast, difl'erences in alinement or wear, or from any other cause, may be taken up in the transmission and each crank carry its portion of the work (Figs. 5, 6).

Each crank wheel 23, 28, carries a wristpin 30 which may be radially adjusted as desired in the corresponding openings 31,

(Fig. 7) so that each of "the pitmen 32 in their straight upward extension may engage the common pivot pin 33, locked by the set screw 34. medially of the length of the pin 33. This screw 34 is carried by the walking beam 35 mounted by the ivot pin 36in the walking beam bracket 3 forming an upwindwheel shaft 18 in such a manner as to efiectively neutralize the windstrain tugs and pulls transmitted from the windwheel in the Wind shiftings and irregular work- I, wardly extending portion of the main frame 9, distrlbuting such work along the ings due to atmospheric conditions. While no the spaced bearings 21, 22, and their relatively long extent are material features in contributing to the life of the structure, the .two gears with connecting rods, walking beam and yoke driven thereby, for taking the drive from the shaft 18 are great fac tors in the efficiency of the mill in giving the mill steadiness of operation under the most trying conditions- On the pin 33 and disposed outside the walking beam 35 and between the pitmen 32 is the Y-yoke 38 forming a reciprocable member driven by the pit'men and guided by the walking beam. The upper arms of the Y are pivotally connected to the pin 33, while the lower stem has a seat 39 with lugs 40 rising/therefrom just above the openings 41 therethrough so that the U-bolt fastening means may firmly lock the angle pump rod 43 over the lugs 40 and against the seat 39. Accordingly in the lift movements of the Y-yoke 38, the load is .taken by the lugs 40, thereby removing shearing action from the U-bolt 42., As the pair of openings in the pump rod 43 are properly spaced to receive the lugs 40 andafford registry with the two openings in the yoke stem, the insertion of the U-bolt and locking it in position provides a tight connection .firm against any working loose (Figs. 5,

, In the main frame 9 adjacent the bearing 27 is the opening 44 (Fig. 3) with which engages the pin 45 for the upper hinge bracket 46 of the vane 47. In the main frame 9 and in line with the opening 44 and therebelow is the bracket 48 rigid with the main frame 9 (Figs. 1, 3). This bracket 48 afi'ords a seat for the lower end of the pivot pin45 through the opening 44. On this pin 45 adjacent the bracket 48 is the lower hinge bracket 49 for the Vane 47.

With the windwheel in gear, or for running, the vane is disposed at right angles thereto and slightly to one side of the wheel center (Fig. 6). The vane is yieldably held in this runningposition-by the governor. Mounted on the pin 45 just above the lower hinge bracket 48 is the outwardly extending arm 50 to the end of which is hooked the adjustable link 51 connected to the U-rod 52 having at its end remote from the frame 9 the hooks 53 extending over to engage a C01]. of the compression governor spring 54. The opposite end ofthe spring 54 1s engaged by the hooks 55 of U-rod 56 similar to the rod 52 but oppositely extending to be anchored by thelink 57 to the vane 47 (Figs. 1, 2).

To limit the swin of the vane away from the windwheel int rowing the windwheel into gear, there is the hook 58 on the frame 59 of the vane. The hook 60 engages th1s frame 59 as guided to position by the rod 61 slidin through the hook 58. The opposite end 0 the rod 61 is mounted by the P111 62 means on the arm 63 having the pivot pin 64 attachlng it to the boss 65 on the main frame 9. This arm 63 is yieldably held in position at right angles to the line of the windwheel shaft 18 (Fig. 6). The arm 63 has lateral extensions 66, 67, each carrying a bolt 68 surrounded by a compression spring 69, so that the heads of the bolts are yieldably thrust against the stops 70 on the frame 9 to form cushions in sudden lunges to which the arm may be subjected. Accordingly when the vane 47 swings the windwheel into gear, the cushion pocket 66 takes up the concussion thereby eliminating excessive strains from the vane, frame and entire windmill structure, a feature materially contributing to the elimination of breakage in the mill and lengthening the life of an easy running machine.

For pulling the vane 47 out of gear, the flexible line or connection 71 is connected to the frame member 59 of the vane and extends about the pulley 72 (Figs. 1, 6) on the arm 63, and thence over the pulley 73 to guide the line through the pump rod opening 74 .in the main frame 9. A swinging of the vane violently by pulling the line 71, or by the wind automatically acting upon the spring governor to throw the windwheel out of the wind, is taken care of to avoid concussion by the vane striking the stop 74 on the arm 63, and the arm yielding at its compression cushion 67.

n pulling the line 71 to bring the windwheel out of gear, the line 71beco1nes taut under the trigger 75 (Figs. 1, 7) to lift this trigger so that in the swinging out of gear of the vane 47, this trigger 75 strikes the end of the arm 76 pivoted on the rod 45. This arm 76 medially of its length has the lug 77 connected to which is the rod 78 having the compression spring 79 holding this rod into yieldable "connection ,with the bracket 80 of the brake shoe 81. This curved brake face 81 is mounted by the arms 82 to swing from the bearings 83 in the long bearing 21 of the main frame 9 (Figs. 3, 6). Accordingly when the overnor con trols the swinging of the windwheel out of the wind for slacking speed, this automatic action does not s'to the wheel necessarily, thereby checking the effective wind action upon the wheel and still permitting the desired service to be performed. This swinging out from governor action does not set the brake. The brake as shown is set only by the pulling of the line 71 which through the trigger 75 causes the arm 76 to yieldably force the brake shoe 81 to engage the inner face 84 of the wheel cone 10.

To preclude a locking of the wheel by this brake, the arm 76 has at its mounting end a lug 85 in the path of the lug 86 on the vane hinge bracket 46. When the vane 47 swings out of gear, the lug 86 moves away flfl r weenie from the lug 85 and thus in the automatic action or even in the manual throw off there is no driving connection between these lugs to effect the brake 81. However the setting of the brake 81 in the manual throw out of the mill, moves the arm 7 6 and likewise the lug 85, so with the brake 81 thus set, any moving of the vane hinge bracket 46 causes its lug 86 to act upon the lug 85 to swing the arm 76 back in following the trigger away from the wheel and thus positively withdraw the brake 81 through the rod 78.

In the structure as shown, oil cups are disposed above the various hearings to provide proper lubrication.
