(Cl. 170-46) 1 This invention relates to a windmill and par- ‘ ticularly to one having a novel folding tail vane and operating mechanism. The present invention constitutes a division of 2 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 pin aimed to provide a structure which operates on ion 50 integral with it. Such gear wheel 50 is the knee action principle and eliminates side thrust on the pump rod, without requiring the use 10 enmeshed with an annular gear or ring 5| having internal teeth, and which ring is secured in the of pitmans, rocker arms, yokes, rollers, slides, or body 39 by screws 52 or otherwise. Also en the equivalent, with a View to conserving power meshed with the teeth of the internal ring gear and attaining a reduction in noise, friction and 51 is a gear wheel 53 keyed to a shaft 54 journaled wear. in and extending through a ?ywheel 55.

Numeral 43 designates a suitable or they fall within the spirit and scope of the inven conventional collar having inward projections 43a at its upper end shaped to ?t into a spiral =' tion. I claim as my invention: groove 4319 at the bottom of the short pipe and 1. A device of the class described having a inward projections 430 at its bottom end shaped to fit into the spiral grooves 43d of the long pipe body, a shaft journaled therein for rotation 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 at tached. Reference character 44 is a governing to said rod, gearing driven by said shaft and operatively connected to said crank, a tower, a spring to keep the mill open in normal wind. Such furling mechanism or any equivalent in— through the action of a wind wheel, a rod to actuate a pump or the like, a crank connected wind vane, a tube journaled in said tower and connected to the wind vane, a tube depending cluding spring 44 is preferably located inside of 55 from the body passing through and beyond the 3 2,407,816 4 ?rst-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,. and a lever to actuate the collar for operation by the furling element for rotating the ?rst men tioned tube relatively to the last mentioned tube. 2. 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 actu-' ate a pump or the like, a crank connected to said rod, gearing driven by said shaft and operatively extending through the tube into the body, a wind wheel and pump rod, a wind vane, a sleeve con nected to. the wind vane and journaled on the tube, said tube and'sleeve having oppositely, di rected spiral grooves, a collar mounted on the sleeve and tube and having lugs engaging said grooves, and remotely operatedifurling 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.
