this application September 22, 1944, Serial No. 555,300

516,310. Divided and 4 Claims.

This invention relates to a windmill and particularly to one having a novel folding tail vane and operating mechanism.

The present invention constitutes a division of my application Serial No. 516,310, filed December 30, 1943, for a Knee action windmill.

Further, as in said pending application, it is aimed to provide a structure which operates on the knee action principle and eliminates side thrust on the pump rod, without requiring the use of pitmans, rocker arms, yokes, rollers, slides, or the equivalent, with a View to conserving power and attaining a reduction in noise, friction and wear.-

Further, it is aimed to provide a structure of the present character in which less material will be required with lighter towers being used, and to provide a structure which is generally improved and is especially light, simple, compact, enclosed, accessible, streamlined, self-oiling, has rotatry motion and straight lift.

The more specific objects and advantages will in part be pointed out and otherwise become apparent from a consideration of the description following taken in connection with drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a View in elevation of the improved windmill;

Figure 2 is a view primarily in vertical section of said windmill;

Figure 3 is a vertical section taken on the line 3--5 of Figure 2; and

Figure 4 is a vertical section taken on the line 4-4 of Figure 2. 1

Referring specifically to the drawings wherein like reference characters designate like or similar parts throughout the different views, the body is designated 39 and has a bearing portion 45 provided with a depending lone furling pipe 41; a short pipe 42 surrounds pipe 4| and is of longer diameter and is journaled in the top of a suitable tower 42. Numeral 43 designates a suitable or conventional collar having inward projections 43a at its upper end shaped to fit into a spiral groove 4319 at the bottom of the short pipe and inward projections 430 at its bottom end shaped to fit into the spiral grooves 43d of the long pipe 4|. In a groove 41a of said collar 43 is a ring 411) pivotally attached at 410 to a forked furling arm or lever 41d to which the pull-out wire 416 is attached. Reference character 44 is a governing spring to keep the mill open in normal wind. Such furling mechanism or any equivalent in cluding spring 44 is preferably located inside of the tower 42 where it is protected from icy weather.

Body 39 has an extended bearing at 45 in which a shaft 46 is journaled and to which a wind wheel 41 is keyed or rigidly fastened. Also keyed to the shaft 46 within the body 39 is a pinion or gear wheel 48 which is enmeshed with a gear'wheel or pinion 49, having a smaller gear wheel or pinion 50 integral with it. Such gear wheel 50 is enmeshed with an annular gear or ring 5| having internal teeth, and which ring is secured in the body 39 by screws 52 or otherwise. Also enmeshed with the teeth of the internal ring gear 51 is a gear wheel 53 keyed to a shaft 54 journaled in and extending through a flywheel 55. A stub shaft in the form of a screw 56 is fastened to the flywheel and the gear wheel 49 is journaled thereon. Said flywheel 55 is surrounded by a bearing ring 51 secured by screws or the like 58 Within the body 39, and ball bearings or the equivalent B0 are interposed between the periphery of the flywheel 55 and the bearing rings 51. The gears are of such construction that they may be transposed to change the gear ratio if desired.

Keyed to the shaft 54 is a crank or knee mem-' ber El having an opening 62 therethrough through which the upper angular end 63 of a pump rod 64 passes.

The body 39 is adapted to be filled to the desired level with a lubricant through an opening covered by aplug 61.

One or more arms 65 may extend from the short pipe 42 and carry a vane 66.

In operation, the wheel 41 will rotate the shaft 46 so that through the gearing, the crank 6| will reciprocate the pump rod 64 in order to operate the pump.

It is to be understood that a side vane (not shown) may be employed to partly close the mill in high winds.

It will be clear that any type of furling device or brake and control therefor may be employed.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

1. A device of the class described having a body, a shaft journaled therein for rotation through the action of a wind wheel, a rod to actuate a pump or the like, a crank connected to said rod, gearing driven by said shaft and operatively connected to said crank, a tower, a wind vane, a tube journaled in said tower and connected to the wind vane, a tube depending from the body passing through and beyond the first-mentioned tube, said rod extending through the second-mentioned tube, a collar on the tubes, a lug and spiral groove connection between the collar and each of the tubes, a furling element,.

through the action of a wind wheel, a rod to actu-' ate a pump or the like, a crank connected to said rod, gearing driven by aid shaft and operatively connected to said crank, a tower having an enclosed upper portion, a wind vane, a tube connected to the wind vane andjournaled in said upper portion, a tube depending from the body passing through the first-mentioned tube, said rod extending through the second-mentioned tube, a collar withinthe enclosure, a lug and spiral groove connection between the collar and each of the tubes, a furling element, and a lever pivoted on the collar and fulcrumed on the tower and extending exteriorly of the enclosure for operation by the furling element, for rotating the tubes relatively to one another. 7

3. In a windmill, a tower, a tube journaled therein, a body mounted on the tube, a pump rod extending through the tube into the body, a wind wheel and pump rod, a wind vane, a sleeve connected to. the wind vane and journaled on the tube, said tube and'sleeve having oppositely directed spiral grooves, a collar mounted on the sleeve and tube and having lugs engaging said grooves, and remotely operated furling means for moving the collar in one direction relatively to the tube and sleeve for rotating the tube and sleeve relatively to one another to furl the wind vane.

4. In a windmill, a tower, a tube journaled therein, a body mounted on the tube, a pump rod extending through the tube into the body,

a Wind wheel and pump rod, a wind vane, a sleeve connected to the wind vane and journaled on the tube, said tube and sleeve having oppositely directed spiral grooves, a collar mounted on the sleeve and tube and having lugs engaging said grooves, and remotely operated furling means for moving the collar in one direction relatively to the tube and sleeve for rotating the tube and sleeve relatively to one another to fur] the wind vane, and a spring for urging the collar in the opposite direction to normally retain the wind vane in an operative position.
