BuzzSaw Gravity Wheel of 1909

Image:BuzzSaw Gravity Wheel - Small Front.jpg

The BuzzSaw "Directory:Gravity Motors" was invented around 1909 and built with heavy duty cast iron. Family members indicate that it ran by itself with overunity and generated free energy that could run a small saw mill. The wheel is referred to as BuzzSaw due to its saw blade like wheel design.

The gravity wheel has an inner wheel with 16 notches and an outer wheel with 8 notches for carrying weights. Weights would shift between the inner and outer wheel with a special gear ratio and weight pattern to obtain overunity. Springs and levers were said to have been incorporated that worked with the nubs on the end of the 12 weights.

The original inventor was said to have built many wooden models of this wheel, from small table-top to large versions (per family members). Once it was perfected, he built the cast iron version that you see today.

Synopsis : Several years have been invested by overunity gravity wheel enthusiast to find the solution but the "missing clue" has not yet been discovered. This is an Open Source design.


How it Works

The BuzzSaw gravity wheel has two wheels supported by an axle. There is an inner wheel and outer wheel, the inner having 16 gullets and the outer having 8. The inner red wheel is attached to and drives the axle. The outer wheel has 4 black spokes on the back and rotates freely on bearings on the axle. When in motion, the weights would freely fall from one wheel to the other.

The outer wheel has a cover that can be removed with screws to insert / remove weights. The original wheel had 12 weights but it is uncertain if all were used or not. The original wheel had a custom 42 tooth sprocket attached for a #60 chain.

It is uncertain at this time what the gear ratio was between the two wheels and how many weights were used. There could be an odd chain gear ratio between the wheels and an odd pattern of weights could have been used. It is also unknown for certain which of the two wheels was the driver.

The wheel was nicknamed "The Heathen" because it was built so heavy duty and difficult to work with when all 12 weights (174 lbs) were loaded.

The following are pictures of the original wheel that was obtained 19 years after the inventor died. It was sand blasted and painted the red and yellow colors. Only the 42 tooth sprocket is original, others being collected for various ratio attempts.

Key Clues & Facts From Family and Friends Functionality


October 2008:

Preston Stroud spoke with a grandson of the inventor before he passed. The grandson confirmed that he had seen the wheel work and that it was a very simple design and concept. He stated the sprocket teeth are the key to its working. He also stated that two of the sprockets were the same size (running between the wheel main shaft and jack shaft). Note that the gravity wheel was recovered with one custom made sprocket with 42 teeth. It was attached to the outer yellow wheel.

Family Comments / History

Built around 1909 from Cast Iron metal. Pieces were cast at different foundry's to avoid knowledge of complete machine.

Family members were told stories from their parents of seeing small wooden versions of the wheel running freely on the kitchen table. Then of larger wooden versions running in the shop.

Molds were found in the shop attic where the original wheel was cast and built

Family members recall seeing the wheel turn freely when they were a child and at the inventor's house playing. They also recall their parents talking about the wheel and seeing it run freely on its own.

Some family members recall the wheel running freely in the shop and driving a saw blade outside the shop using a belt.

Axle and Chain

Chain Size: #60

Axle Diameter: 1 5/16"

1/8" spacer is on the axle between the two hubs of the inner and outer wheel

Outer Yellow Wheel Facts

Outer yellow wheel turns freely on the axle

Outer wheel has 8 gullets / notches for carrying weights

Outer wheel has 4 black spokes on the back to attach it to the axle and runs on bearings.

Outer wheel has a cover that can be removed with screws or bolts so that the weights can be inserted or removed from the wheel.

Outer wheel is about 3 foot across on the outside and 2 foot on the inside.

One original 42 tooth sprocket came with the wheel. It was hand cast iron made soley for the hub of outside wheel

Gullet Spacing starting at a random tooty on the outside wheel: #1- 10" . #2- 9 3/4" . #3- 9 7/8" . #4- 9 7/8" . #5- 10" . #6- 9 3/4" . #- 7- 10" . #8- 10"

Inner Red Wheel facts

Inner red wheel is attached to and moves with the axle.

Inner wheel has 16 gullets / notches for carrying weights.

Inner wheel has 4 teeth that stick out towards the inside. They could have been used for an alignment / holding rod OR for holding a ring with levers & springs.

Gullet Spacing starting at random tooth on inside wheel numbered 1-16 point to point: #1- 5" . #2- 5" . #3- 5" . #4- 4 7/8" . #5- 4 7/8" . #6- 5" . #7- 5" . #8- 4 3/4" . #9- 5" . #10- 5" . #11- 4 7/8" . #12- 4 7/8" . #13- 5" . #14- 4 7/8" . #15- 4 7/8" . #16- 5" .

Weights Facts

12 weights came with the original cast iron wheel.

Each weight weighed 14.5 lbs for a potential total of 174 lbs in wights.

Each weight has a nub sticking out on the end.

One nub is slightly longer than the other. Short nub is 5/8" and long nub is 1". It is speculated that the longer nub on the weight could have been used by levers that worked with springs.

Weight circumfrance: 14 1/2" round

Each weight is 3 3/8" wide without the nubs on the end.

Levers / Springs

It was stated that the front of the red inner wheel had a ring / circle attached with levers sticking out and springs attached. It is unknown if the springs / levers were used to help the weights transfer at high speeds or if they were key to making the wheel out of balance.

Weight Transfer Times

If the red inner wheel was the driver, wheel motion of weight transfer could flow from the outer wheel at 12 oclock to the inner wheel and from the inner wheel at 6 oclock to the outer.

If the outer yellow wheel was the driver, the weights would transfer from the outer yellow to the inner red wheel at 4:30 oclock and from the inner red to the outer yellow wheel at 10:30 oclock.

Comments from the Inventor's Children & Grand Children

The following are some memories from the inventor's children and grand-children:

"He remembers seeing the machine run! Out there on the farm, before he went off to war. He said it clattered loudly and was of the configuration that ... weights went up and transferred into a second, or inner wheel that apparently descended...I suppose grand father (inventor) tried to arrange the movement so that there was more weight coming down with gravity than was traveling upwards against gravity ...and beating out friction hopefully as well..."

"He went on to say that, as mentioned earlier, grandfather could not make it produce any practical work... He did feel that it would keep running but for how long or indefinitely, he did not elaborate.."

"My Aunt witnessed the machine running and that it shook the building. As I told you, my father told me the same."

"One aunt swears she and a girl friend saw it running and a cousin seems to recall that the two wheels were counter rotating. A total of three individuals claim they saw it in operation. Said to be very noisy with heavy vibration. Another said that it did not seem to produce much power."

"It was also stated that a number of wooden test wheels were constructed previous to the cast/forged iron model that now exist. One of these test models allegedly over run with acceleration that it flew apart putting a weight through the single board siding of the shed he was working in. They remember him using a timber levered against the axle to slow it down and stop it."

"Third party input claimed that the buyer of the property found a sealed off portion in the loft of the building, containing wooden parts and pieces of earlier test models. The disassembled wheel was eventually moved from the building and ended up leaning against an apple tree where Doc found it."

Comments from a Person Who Worked With the Inventor

The following are some comments from DockFeelSoGood, whos father worked on the wheel with the inventor. They may provide some insight on how it could have worked.

"you can stare at this thing all day long , go home and build one that looks just like it and it wont run BECAUSE you can't think in equal divisions of a 360 degree circle. That's where everyone makes their mistake"

"you have to balance the wheels, then when you add the weights it's deliberately thrown out of balance"

Something was said about a hammer hitting something to make the weights transfer quicker.

The front of the red inner wheel had a ring / circle attached with levers sticking out and springs attached. It is unknown if the springs / levers were used to help the weights transfer at high speeds or if they were key to making the wheel out of balance.

The levers he said it had on it for transfer had springs attached somehow

He draw a picture of the levers many years ago and it looked like a circle with some sausages attached. Like kielbasa sausages as springs.

The ring would have been attached to the outside of red wheel. Must of been some kind of kick levers with springs to help transfer

The ring on the red wheel was described as having spider legs. It was a 4 or 8 legged spider. I think he only drew 4 sausages / springs but it could have been more. I think up near end was a jointed piece. When the weight fell into a gullet / slot it stretched the spring on that lever.

A hammer was mentioned that drove something and thumped something on the frame

An uncle who worked for the inventor said as he remembered, it was 7 weights going down as 1 rose

In order for this thing to run, it has to fight for equilibrium, which it never can achieve. Recall my ole man said "One wheel has to fight with the other".

The hammer, "it looked like a regular blacksmith hammer" I recall it was somewhere in the 4 lbs range or a little above with a length of about 14 to 16", perhaps even 18. It was a light sledge with the handle sawed off

The blacksmith hammer , it [the head anyway] hung below the centerline of the axle, I took it that it slapped on the frame leg and was driven by a connecting rod of some sort. He explained that it made the weights "fly faster" in transfer from one wheel to other. It did not bash on the weights them selves. He surmised that it wouldn't be necessary until we had a controlled movement.

"the spider legs deal", he explained that it went on the side of the red wheel and was attached by them existing bolt holes (4 teeth on the inner red wheel). I would compare it to a clutch pressure plate attachment deal with fingers radiating outward to the edge of the red wheel a full 360 deg. There again, his impression was that it helped the weights transfer faster. There again we thought it unnecessary until we had controlled movement.

The spider legs / lever & springs - "it run with the motion of a horses head".

Something had a certain amount of slop built into it to let it oscillate back & forth". Dad said it could NOT be 100 % rigid.

Remote Viewing

On March 3, 2008, Brian from performed a remote viewing ofthe BuzzSaw Gravity wheel.

Brian thinks the inner red wheel is the driver. He thinks the wheel had 5 weights with 4 going down and 1 going up. Brian also thinks there is a circular spring that helped the wheel stay out of balance.

Below are the pictures from Brian's remote viewing:
