PATENT f Application september 28, 1f9s3,seria1,N0. '691,394 In Canada January 23, 1933 2 Claims.

The invention relates to improvements in windwheel governors and an object of the invention is to provide a governor which will maintain the speed of rotation of the windwheel within a selected speed range and which is arranged so that one can easily adjust it as desired to vary such speed range.

A lfurther object of the invention is to provide a. Windwheel having the blades thereof mounted for radial out movement under the action of cen- '20 insuring that the blades will shift radially an equal amount and simultaneously.

A further object is to construct all parts in a simple, durable and inexpensive manner and so that the various working parts can be effectively lubricated and such that the various parts are easily accessible for repair, inspection or adjusting purposes.

With the above more important objects in view, the invention consists essentially in the arrangement' and construction of parts hereinafter more particularly described, reference being had to the accompanying drawing, in which:-

Fig. 1 is a side elevation of a windwheel equipped with my invention.

Fig. 2 is an enlarged detailed vertical sectional view centrally through the governor.

Fig. 3 is a front view of the parts, the cone and cover plate having been removed.

Fig. 4 is a perspective view of the inner end of the sleeve and showing the spiral slot therein.

Fig. 5 is a perspective view of part of the vane or blade.

Fig. 6 is a perspective view of the inner end of 45 the sleeve and associated parts.

In the drawing like characters of reference indicate corresponding parts in the several figures.

The windwheel stand or trestle 1 has the platform 2 thereof supporting an electric generator 3 50 which is mounted in any suitable manner on the table so that it can turn around its vertical axis under the influence of the tail 4 which is attached to the generator by a bar 5. The generator driving shaft is indicated at 6.

The above parts are of ordinary construction and a further detailed description is accordingly not considered necessary.

The forward end of the motor shaft is tapered and frictionally receives the hub lof a disc 8, the disc being supplied vWith a rim 9 Vwhich carries a front inturned flange 10. ,A .-nut 11 is screw threaded on .the forward endr of `the shaft and holds the hub in place andthe arrangement is such that the hub turns with the shaft,

A cone shaped deflector12 isA provided, the vdeflector having the base thereof supplied with an out vturned flange which is fastened by bolts 12V to the flange v10. To the base of `the deector, I secure permanently in-any well known manne-r a closure plate 13 which hasA the central part thereof forwardly `bulged in the manner Abest shown in Figure 2 inorder toaccommodate cer-1 tain internal parts later described. The disc, rim and closure plate form a casing which contains certain operating parts and which can be filled with oil to lubricate such parts.

To the rim 9, I permanently fasten a plurality of equi-spaced, radially disposed, similar sleeves 14 which actually project centrally through the rim and are grouped in diametrically opposing pairs, there being four sleeves herein shown although the number could be increased or diminished without departing from the spirit of the invention.

In each sleeve, I mount rotatably a spindle 15 Which has the inner end thereof provided with a pin 16, the pin having the projecting ends thereof slidably received in similar spiralling slots 17 formed in opposite sides of the sleeve. On each sleeve, I mount two washers 18 and 19, the washer 18 in each instance engaging the ends of the pin which protrude beyond the slots (see Figure 6).

The motor shaft is longitudinally bored and in the bore 20 I force tightly the rear end of an extension shaft 21 which rotates with the motor shaft. The forward end of the extension shaft receives slidably a sleeve 22 which is provided with pairs of lugs 22. To each pair of lugs I connect by a pivot pin 23 the forward end of a link 24 which has the rear end thereof forked to span the washer 19 and to which it is attached by pivot pins 25.

According to the above arrangement, it will be apparent that the forward end of the extension shaft 21 is connected by the links to the several washers carried by the sleeves 14. On each spindle, I mount slidably a further Washer 26 and between the washer 26 and that 19, I place a coiled spring 27, the spring being mounted on the sleeve. l The several washers 26 are connected together by 110 similar tie rods 28, suitable turn buckles 29 being inserted in the rods so that the same can be adjusted. It will be apparent that the tie rods hold the washers 26 against out movement and accordingly the springs operate to hold the pins 16 normally at the inner ends of the slots 17.

To the spindles 15, 5I secure in any suitable manner similary blades `30the blades being all posi,-

tioned on the spindles so that they have their` least pitch to the wind when the pins'16 are at the inner ends of vthe slots 17. Actually I have shown a plate 31 securely fastened as by welding to the spindle, the blade channeled to receive the spindle and the plate fastened as byscrews-32 to the back of the blade. This allows of the ready removal of the blades When required.

According to the construction provided, it will be seen that up to the time that the pressure of the springs is overcome, there Will be no turning crease in the wind velocity, the turningl of the bladesbeing effected by the pins in the slots.

HWitli this type ofgovernor, Il am able to cause the wheel to rotate Within a limiting speed range for known wind velocities andaccordingly, am able to limit the current delivered by the generator. The sleeve 22, the extension shaftand the links insure that the several spindles will move out and in together and while they are not necessary to the operation of the device, they are desirable.

What I claim as my invention is:-

l. In a windwheel, in combination, a rotatably mounted closed casing, a plurality of radially disposed sleeves permanently secured to the Wall of the casing, a blade carrying spindle rotatably mounted in each sleeve and endwise shiftable under the action of centrifugal'force, pins carried by the inner ends of the spindles and slidably received within spiralling slots provided in the sleeves and adapted to rotate the spindles to increase the pitch of the blades as the spindles move out under the action of centrifugal force, a

Washer slidably mounted on each sleeve Within the casing,l adjustable tie rods connecting the washers together, a second washer on each sleeve engaging the pin and a spring interposed between the first and last washer.

2. In a windwheel, in combination, a rotatably mounted closed casing, a plurality of radially disposed sleeves permanently secured to' the wall of the casing, a blade 'carrying spindleV rotatably mounted in each sleeve and endwise shiftable under the action of centrifugal force, pins carried by the inner ends of the spindles and slidably re-` ceived Within spiralling slots provided in the sleeves and adapted to rotate the Aspindles to increase the pitch of the blades as thespindles move out under the action of centrifugal force, ra Washer slidably mounted on each sleeve within the casing, adjustable tie rods connecting the Washers together, a second washer on each vsleeve soA engaging the pin, a spring'interposed between the first and lastwasher and means coupling the j.,

several spindles together so that JOSEPH W. YOUNGBERG.r
