UNITED STATES PATENT FRED WAIDNER, 0F MISHAWAKA, INDIANA.

HINGE FOR WlNDMlLL-RUDDERS.

SPECIFICATION forming part of Letters Patent No. 515,630, dated February 27, 1894.

Serial No. 475,997. (No model.)

To all whom it may con/cern:

Be it known that I, FRED WAIDNER, a citizen of the United States, residing at Mishawaka, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Hinges for Windmill- Rudders, of which the following is a specification. Y

This invention relates to that class of windmills in which the sails are turned in the direction of thewind by means of a vane or rudder and also where the wind wheel is pivoted in such a manner` that the pressure of the wind tends to swing the same out of play or edge to the breeze by means of a rudder when the wind `becomes too strong; the rudders or vanes heretofore used on wind-mills, were usually hinged to the revolving frame by a crooked hinge or a simple eye and hook, the lower hook usually made longer so that the end of the rudder would be slightly raised in throwing the mill out of gear so that the same would return to its natural position of its own accord when desired to throw the mill in gear. It has been demonstrated by practicable experience, that the so called crooked hinge does not work satisfactorily in a great many cases, in view of the fact that the exposure to the weather soon rusts the hinge, as well as the springs that are often used to cause the rudder to regain its natural position when the mill is thrown into gear, and therefore they soon become worthless; in order to remedy this matter, I have invented a hinge, the novel construction of which will be hereinafter more fully explained.

In the drawings,-Figure l, is a side view of a rudder attached to a standard by means of my hinge. Fig. 2, is a top view. Fig. 3, shows the position of rudder when mill is out of gear. Fig. 4, shows a top view of rudder and hinge when in position, as shown in Fig. 3. Fig. 5, is a view of adjustable connecting rod. Figs. 6, 7 and 8, shows slot in top beam of rudder, and nut and flat headed bolt with a round aperture, by means of which the connecting rod is aiiixed to the top beam of rudder. Fig. 9, shows a perspective view of a mill and rudder attached to same by means of my hinge.

Like letters of reference indicate corresponding parts in all the figures of the drawings.

A, in the drawings is the rudder.

B, is my improved hinge consisting of an L shaped plate c, having the slot d, and a small semi-circular projection e, extending laterally from the plate, the same havingan opening to receive the end of an adjustable connecting rod h, the other end of which is connected to the top beam of the rudder by means of a threaded bolt le, and nut 7o', the bolt having a dat head with an opening l, to receive the other end of the rod h, the dat head of the bolt 7e, is made so that the same can easily be inserted through a slot m, in the upper horizontal beam of the rudder, (see Figs. 7 and 8) and by means of the same and the rod h, the rudder can be adjusted to raise to any required height when the mill is thrown out of gear by the velocity of the wind, thus it will be seen that the higher the rudder is adjusted to raise in order to throw the mill out of gear, the greater the velocity of the wind must be to do so and vice versa; it will Y also be seen that the rudder can be so adjusted that when the wind becomes too strong it will throw the mill out of gear of its own accord and vice versa as soon as the wind modcrates.

n, is a plate with a laterally extension n having an opening for the reception of avertically extending arm o; secured to the lower horizontal beam of rudder fr, is a perpendicular extending arm secured to the upper horizontal beam ot' rudder and works within the slot d. Thus it will be seen that when the rudder is turned to the left from the position shown in Fig. 2, that it will canse the arm r, to slide toward the opposite end of slot d, thus causing the rudder to be raised as shown in Fig. 3, the angle of the rudder being such that it will return to its former position of its own accord as heretofore described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A hinge for wind-mill rudders consisting of a plate having a slot d, the lateral projection e, having an opening to receive the end of an adjustable rod h, which is connected at its other end to upper beam of rudder by a bolt zontal beam of ruddenall substantially as and f n for the purpose hereiny shown and described.

f In testimony that I claim the foregoing as my invention I have signed my name in the to presence of two subscribing Witnesses; f

FRED WAIDNER.
