SPECIFICATION forming' part of ietters Patent No. 400,195, dated. March 26, 1889.

Application iiled May 31, 1888. Serial No. 275,567. (Model.)

To all wiz/0m t may concern:

Be it known that I, GUSTAV DIETERT, a citizen of the United States, residing at Kerrville, Kerr county, Texas, have invented certain new and useful Improvements in 'Windmills, of which the following is a full speciiication.

My improvements are designed more particularly for use in connection with that class of wind motors known as the vertical wheel g and the said improvements consist in certain features of novelty, which will now be described, with reference to the accompanying drawings, and then more specifically pointed out in the claims hereto annexed.

In said drawings, Figure I is a side elevation of a windmill, showing a portion of the wheel and also a portion of the tail, and the trelliswork or tower omitted. Fig. In is a detail view of the ball-and-socket joint hereinafter referred to. Fig. Ib is a sectional view taken on the line b b, Fig. I, Fig. II is a plan View of the same. Fig. III is a detail view,partly in vertical section, showing the crown of the tower with the wheel-support fitted thereon, portions broken away. Fig. IV is a detail view looking in the direction of the arrow in Fig. Il, the arms for supporting the wheel being broken away.

1 represents a portion of the wind-wheel upon the shaft 2which latter is journaled in suitable bearings or boxes, 3, carried by the two arms 4;. These armsare preferably cast integral with the sleeve or collar 5, which, together with said arms, forms the wheel-support.

6 is the part which will be hereinafter designated the crown of the tower, which may be secured in any suitable manner to the top of the trelliswork of which the tower is formed. Projecting upwardly and axially from this crown 6 is a tenon 0r journal, 7, around which the collar or sleeve 5 is adapted to revolve, the latter resting upon a shoulder or flange, 8, on said crown. Formed around this tenon is a peripheral groove or channel, 9, in which engages a set-screw or pin, 10, driven through the collar or sleeve 5 for preventing the latter from being lifted vertically from said tenon, but at the same time permitting its free revolution thereon. Passing vertically through the tenon and 'crown 6 is a hollow shaft, 11, which at its lower end is suitably stepped'in a bearing or step, (not shown,) and at its upper end is provided with a beveled gear, 12, adapted to be engaged by a similar gear, 13, mounted upon the wheel-shaft 2.

The tail or rudder 14 is provided with a stem, 15, which latter is planted in a stock or socket, 16, hinged to an arm, 17, the latter being secured to or made integral with the collar or sleeve 5, or with one of the arms 4, as shown in dotted lines in Fig. I. These two parts. V16 and 17 are hinged together by means of a ball-and-socket joint of the usual and well-known construction, the arm 17 bearing the ball 18, while the stock 16 carries the socket 19, the latter being made in two sections, as shown in dotted lines in Fig. I and in full lines inFigs. I Ib, and provided with a lateral groove, 21, for the passage of the arm 17 as the rudder turns, and the lower section being provided with a vertical notch or groove, 20, in order to permit the tail or rudder to be folded downward in a vertical position when the same is to be removed or when it is desired to have the mill remain inoperative. Secured around this stem 15 is a ring or collar, 21, which is provided at both sides with rings 22 for the attachment of cords 23 24, the former passing around the pulley 25, which is mounted in an approximately horizontal position in the recessed end of an arm, 26, and thence over a pulley, 27, which is mounted vertically and directly over the hollow shaft l1 in the bifurcated end of the arm 28. The cord after passing over this latter pulley descends through the hollow shaft within the reach of the operator, whereby he may be enabled by drawing upon said cord to pull the tail or rudder toward the wind, andconsequently throw the wind-wheel out of the wind or with its edge toward the same. The arms 26 and `2S are preferably made integral with a bracket, 29, secured by any suitable means to the side of the collar or sleeve 5.

The tail is maintained in the wind by means of a weight, 30, which is mounted upon one arm of an angle-lever, 31, and held at any desired position on said arm by means of a setscrew, 32, it being prevented from slipping from said arm by an ordinary stop or pin, 33,


inserted through the end of the latter. The other arm of this angle-lever is connected by means ot' the cord 2i to the other of' said rings 22, and the lever is pivoted by means of a bolt, 34-, to a plate, This plate is prefer ably cast integral with two converging arms, Sti, which l'orni a bracket, they being secured at their d iverging ends to the revoluble sleeve or collar by means of; the bolts 37, as shown.

'3y the construction thus described it will be seen that the weight 23() may be placed `upon the anglewltiver to hold the tail to the wind as lon as the latter remains ai a certain velocity; but when the velocity increases the weight will be overcon'le and the wheel and tail or rudder will change position relative to one another.

In order that l may regulate the angle ol the wi 11d-wheel to the wind, I provide the stock or socket llt with an cutwardly-projecting arni, 3S, which it is preferable to make in tegral with the stock, and which is provided at its inner end with the long set-screw The end oi this set-screw is adapted to abutagainst the side ot' the arm i when the wind decreases and the weight 3() returns the rudder to its normal position, and it will be seen that by adjusting this screw the normal position ot' the rudder relatively to the windwheel maybe varied to a considerable degree, and thus prevent the wheel from turning broadside to the wind whenever the pressure ci the latter becomes less than that of the weight 30. rlhe tail is prevented from taking a downward turn by means of a stay-rod, iti, which is secured to a hook, Lt1, on the yoke or brace 49, that projects from one journal box or bearing to the other over the wheel 13, and thus braces the arms 4, and this rod is secured at its lower end to an rrln, 43, which vis preferably made integral with the ring or collar 2l on the stem 15. The purpose of this' arln 13 is to prevent the rudder revolving transversely to a horizontal position, as it is readily seen that if the rod 4x0 were attached directly to the stem, or even to a link in the collar thereon, the leverage would not be suticient to keep the stock in which the rudder is mounted from revolving on the ball of the joint.

Having thus described my inventiomwhat I claim as new therein, and desire to secure by Letters Patent, is

l. The combination, with the revolublc wheel-support, having the yoke 42, and the tail or rudder having a stem, of a ball-andsocket joint, by which said stem is secured to said wheel-support, a collar or ring, 21,011 said stem, and a rigid arm projecting upwardly i from said ring and connected with said yoke, substantially as set forth.

2. In a windmill, the combination, with the stem 15, the collar 5, the arm 17, secured thereto, and the ball 18 on said arm, of the stock 16, receiving said stem, the socket it), made integral with stock 16, receiving said ball, and the arm 3S, made integral, with said. stock and carrying a setscrew, as set forth.
