UNITED @TATEd PAEENT THOMAS W. HENNING, OF SAN ANGELO, TEXAS.

'WINDIVLI-LL.

To all whom it may concern Be it known that T, THOMAS W. HENNING, a citizen of the United States, residing at San Angelo, in the county of Tom Green and State of Texas, have invented new and useful Improvements in Windmills, of which the following is a specification.

This invention has relation to wind mills and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide in a wind mill structure a rotor mounted for horizontal rotation and which includes a vertically disposed j ournaled shaft suitably mounted in a frame. A hub'portion is fixed. to the shaft and arms radiate from the said hub portion. The arms are arranged in upper and lower sets and the outer ends of corresponding members of the sets are connected together by uprights. Vanes are pivot ally mounted between corresponding members of the sets of arms and are arranged to swing and describe approximately one quarter of a circle. Plates are mounted upon the arms and are adapted to limit the outward swinging of the vanes with relation to the arms and the said vanes carry at their upper and lower ends pins adapted to engage the edge portions of said plates. These pins are also adapted to engage the sides of the arms or sockets provided therein whereby the inward swinging movement of the vanes is limited. The free edge portion of one vane is adapted to slightly overlap the pivoted edge portion of the adjacent vane and this arrangement is preserved through out each set of vanes. Therefore when the outer most vane of a set of vanes moves to a closed position it encounters the side portion of the next vane and starts the last mentioned vane toward a closed position and as the last mentioned vane closes it encounters the next adjacent vane and operates in a similar manner upon the same. When the vanes begin to move to an open position the innermost vane starts first and as it begins to move in an outward direction in relation to the arm it swings the next adjacent vane which in turn swings the outermost vane in the opposite direction from that just above described.

In the accompanying drawing :Figure 1 is a side elevation of the wind mill. Fig. 2 is a horizontal sectional view of the same. Fig. 3 is a perspective view of a portion of Specification of letters Patent.

the same. Fig. 4 is a detailed top plan View of a portion of the same.

The mill comprises a frame 1 which may be of any type or form and constructed of iron or wood as desired. A shaft 2 is vertically disposed and suitably journaled in the frame 1. This shaft may be connected with other shaft sections if desired, or a wheel 3 may be applied directly to the shaft 2 for the purpose of transmitting rotary movement from the said shaft to other movable parts not shown. A hub block 4 is mounted upon the intermediate portion of the shaft 2 and is secured thereto by means of set screws or other suitable devices. Arms 5 radiate from the upper and lower end of the hub block f and the corresponding members of the two sets of arms are located in the same vertical plane or approximately so. The corresponding members of the two sets of arms are connected together at their outer ends by uprights 6. It is to be understood that any number of arms 5 may be employed to carry out the principles involved in the invention.

Vanes 7 are located between the members of the corresponding pairs of arms 5 and are mounted shafts 8 which are journaled in the arms. The vanes 7 are provided at their upper and lower ends with pins 9 which project beyond the end portions of the said vanes and which when the vanes are swung toward the arms are adapted to enter notches 10 provided in the side edges of the arms. Plates 11 are fixed to the arms 5 and are provided with end portions 12 which project into the paths of movement of the pins 9. The end portions 19. of the plates 11 limit the swinging movement of the vanes in one direction and the arms 5 limit the swinging movement of the vanes in an opposite direction. These vanes are arranged in sets and the outermost members of each. set are so positioned that they slightly overlap the adjacent edge portions of the inner members when the vanes are closed with relation to the arms Consequently when the outermost vane closes its free edge portion encounters the next adjacent vane and starts to close the same. The action of the wind finally closes all of the vanes and as the vanes begin to open the swinging move ment of the innermost vane initially starts the swinging movement of the next adjacent vane and so on throughout the set of vanes.

The operation of the mill is as follows: WVhen the wind is blowing the action of the Wind will close one set of vanes in the path of movement of the wind and open a set of vanes at the opposite side of the shaft from the set of vanes which has been closed. Consequently the shaft and arms are rotated and each time that a set of vanes is presented toward the wind they are closed and as they turn around the shaft they gradually open and are again closed. This maintains the rotor in a state of rotation and the operation will continue so long as the Wind continues to move or blow. If desired any suitable form of brake mechanism may be applied to the shaft 1 but as such attachments are common eXpedients it is thought that further reference to these means is unnecessary.

Having thus described the invention What is claimed as new is In a wind mill ihaving a rotor provided With parallel arms having at their side edges sockets, vanes pivoted between the arms and adapted to overlap each other at their edge portions, plates attached to the arms adjacent the sockets and having end portions standing out at right angles to the arms and adapted to receive between them the free edge portions of the varies, and pins carried by the vanes and adapted to engage the outstanding end portions of the plates when the vanes are in one position and adapted to enter the sockets when the vanes are in another position, whereby the swinging movement of the vanes is limited approximately to one quarter of a circle.

In testlmony whereof I affix my signature 1n presence of two wltnesses.
