GOVERNOR Filed Sept. 28, 1937 2 Sheets-Sheet 2 Inventor Attorneys Patented Aug. 9, 1938 UNITED STATES PATENT OFFICE 2 Claims.
This invention appertains to new and useful improvements in governors for wind motors such as windmills and the like.
The principal object of the invention is to provide a governor for automatically regulating the speed of the wind driven propeller.
Another important object of the invention is to provide a governor structure which will be simpleacting and substantially fool-proof.
Other important objects and advantages of the invention will become apparent to the reader of the following specification.
In the drawings:-
Figure 1 represents a side elevational view of the assembly.
Fig. 2- is a front elevational View of the propeller and governor.
Fig. 3 is a fragmentary longitudinal sectional View showing the governor.
Fig. 4 is a fragmentary plan view of one of the weight members.
Fig. 5 is a fragmentary perspective view of one of the weight members.
Fig. 6 is a cross sectional view, taken substantially on the line 6-45 of Fig. 3.
Referring to the drawings, wherein like num erals designate like parts, it can be seen that numeral 5 denotes the usual skeleton tower for supporting the generator t which is driven by the wind propeller I, the propeller being located on the shaft 8.
As is clearly shown in Fig. 2, the propeller I is provided with the hub 9 and to this hub is secured the governor mechanism generally re- J ferred to by numeral I0.
This governor mechanism consists of the elongated barrel I I provided with ball bearing mounts I2 in the opposite ends thereof and through these ball bearing mounts are disposed the cylindricalshaped weight members I3l3.
The outer ends of these weight members I3 are bifurcated as at It for receiving the broad paddle blades I5 which are secured to the bifurcated portion by suitable securing means IS.
The inner ends of these weight members I 3 are reduced as denoted by numeral I1 and then twisted to a screw form I8. The barrel II adjacent each end thereof is provided with a pair of closely spaced pins I9I9 disposed therethrough transversely and between each pair of pins I8I9 is disposed the adjacent screw form I8. 7
At the intermediate portion of the barrel I I an anchoring pin 20 is located and from this pin in opposite directions extend the coiled extensible springs 2I2I, each of which connects at its outer end to the adjacent end of the corresponding screw form I8 as is clearly shown in Fig. 3.
On the inner end portion of each of the weight members I3, that is inwardly of its screw form I8, is located a stop pin 22 between which and the corresponding ball bearing mount I2 a coiled compressible spring 23 is located and in convoluting position on the corresponding weight member l3.
It can now be seen that as the barrel II is rotated by the propeller I, and speed increases, the weight members I3 move outwardly due to centrifugal force and as they do so the same rotate due to the disposition of the screw forms I8 between the pins I9-I9. This action causes rotation of the blade-like paddles I5 so that they will move or rotate from a position on a plane with the propeller I to the other extreme as shown in Figs. 1 and 2, that is at right angles to the plane of the propeller l and this, of course, acts as a retarding means for the propeller.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is Y 1. Retarding means for rotary structures comprising a barrel secured toa rotary structure toproject laterally therefrom, a shaft longitudinally disposed in the barrel and projecting at one end from the free end of the barrel and being slidably disposed therein, a paddle on the outer end of the shaft, said shaft provided with a spiral formation at its inner end, an anchor in the barrel, an extensible coiled spring in the barrel having one end connected to the anchor and its opposite end to the spiral formation, a coiled compressible spring on the shaft having one end connected to the inner end portion of the shaft and its outer end abutting the adjacent end portion of the barrel.
2. Retarding means for rotary structures comprising a barrel secured to a rotary structure to project laterally therefrom, a shaft longitudinally extending from the outer end of the barrel and journally supported therein, a paddle on the outer end of the shaft, said shaft being longitudinally slidable in response to centrifugal force, spring means for retracting the shaft when relieved of centrifugal force, and means for causing rotation of the shaft as it slides in the barrel, said means for causing rotation of the shaft consisting of a pair of closely spaced pin members disposed across the interior of the barrel, said means for causing rotation of the shaft further including a spiral formation on the inner end of the shaft ridably disposed between the pin members.
