Discussion about the Lockridge Device

[hiwater]

Because according to my search, the Brush Assembly that is shown on Bedini's Video Lockridge Replication does NOT look like the original Dynamo type but a MODIFIED Assembly from a Delco-Remy STARTER Brush from those times.

Yes that exactly what they are. Modified to fit their use in that machine, In the dvd they talk about the old style delco , which had the 

better style of brushes and brush holders in that they could have used. Those brush assemblies you talk about are still in use today for the older vehicles.

NOTE-- I dont have a phone that i can use to do what you are asking. But my daughter does. Ill try to get her to take a picture and figure out how to get it posted. In the mean time ill look on the net to see if i can find a picture of the brushes and holders in the delco case.

I Looked on line for some pictures. The only thing I can come up with is searching for DELCO STARTER-GENERATOR REPAIR.

These brush assemblies in the videos are the same as in the 6-12 volt delco generators we are talking about. In the S/G the brushes are wider to accomodate 2 commutator bars for starting. Hpoe this helps for now. Hiwater.

@hiwater,

Please, if you have a Delco Remy Old type Dynamo, can you share here the ORIGINAL Brushes ASSEMBLY IMAGES (Brush plus Mounts, housings and Springs) that came with those Dynamos?

Because according to my search, the Brush Assembly that is shown on Bedini's Video Lockridge Replication does NOT look like the original Dynamo type but a MODIFIED Assembly from a Delco-Remy STARTER Brush from those times.

This type of Brush Assembly Design allows for us to be able to ADJUST FREELY, without any limitations.

While the Brush Assembly type that MOUNTS on Upper Caps (like my FORD Dynamo) do NOT have that adjustment freedom.

Note that the brushes used on this Lockridge replication had a HOLE from factory where a bolt mounts it on rocking arm, while spring mounts on the rotating pin.
If you search for Delco Remy Starter Brushes, it shows exactly these types with a hole, there are square or plain rectangular, but ALL have a hole.

Look below at the Replacement Parts for a Delco-Remy Starter from those times (All Delco-Remy Starters come in a set of FOUR Brushes)

That last image above is a: "BRUSH HOLDER" REPLACEMENT for a Delco Remy Starter, as it is also the SWIVEL or ROCKER ARM, where Brush is mounted with an 8/32 Bolt, and PIN passes through base hole, it is NOT Metal but INSULATED MATERIAL....Now compare it with First image here from Bedini's video...of course, this is a new replacement part, NOT the original.

Now, on Image below is the "Delco-Remy Starter Repair Kit" we can see all separated parts, and of course, on this Starters, Two Brushes were Positive (Insulated by Plastic Brush Holder (Black)) as the other two were to Negative Ground, so, TWO of the Brush Holders were made of Metal, plus we also see two thick wire Jumpers...one for negative brushes and other for positive.
We can also see on the Right next to the Pins, the Back Mounting Plates, only comes two, we need FOUR.

We can see now a better view of how this Lockridge Device REPLICATION was BUILT...using components from other devices, like Starters...

Thanks @hiwater for your help!

Isn't 8/32 the same as 1/4?

Hi Prajna,

In the U.S. a 8/32 bolt means a bolt with a size of 8 and a thread pitch of 32 threads per inch.

On image above is the KEY about understanding the Motor-Generator Differences, related to EMF and Currents on Both Systems.

Both Machines are Rotating on the SAME DIRECTION, and Upper Brushes are Positive for both Machines.

1- On Dynamo as Generator: EMF and Currents travel on the SAME Direction, both going to the Upper Positive Brush.

2- On Dynamo as Motor: EMF and Currents are OPPOSED, as Currents travel AWAY from upper Positive Brush.

From above data collected from an old book...we can realize that CURRENTS on Both Systems (Motor-Generator) MUST RUN ON THE SAME DIRECTION, when working together on the same Armature Circuit, in order for our Device to work as we want to.
If Currents are OPPOSITE on Both Systems SHARING the SAME ARMATURE, they will just CANCEL to a big ZERO.

Anyways, that is just the way I see it...

Hello All,

Ok, so I quoted myself on my prior post, basically to bring up the image above from the Hawkins Book Vol 2...

And I "FUSED" BOTH Systems into one CAD IMAGE, using the same, exact spec's as shown on the Book Image...:

For better understanding all Flow Circular Arrows have a STARTING DOT and an end Arrow, showing the FLOW DIRECTION.

All the Circular Red Arrows are CURRENTS FLOWS, for Dynamo (Generator) and for Motor.

The Black Circular Arrows means EMF DIRECTION.

As we see on Book Image, the EMF for BOTH SYSTEMS follow the same direction, or from Low (Negative) Brushes to High (Positive Brushes).

So, on my image -to simplify things- I have set EMF starting on BOTH Negative Brushes (Low) and traveling to BOTH Positive Brushes (High)

While on the Dynamo, the Currents flow from Low Brush to High (Positive Brush) or the SAME EMF DIRECTION.

On the Motor, EMF also goes on the same direction as Dynamo (Bigger Circular Arrows on Book) BUT Currents flow from Low (Negative Brush) to High or Positive Brush.

Please, analyze this Image carefully...because all we need to achieve our goal, is that BOTH SYSTEM CURRENTS, FLOW ON THE SAME DIRECTION...

IMHO, the way I see it, is that when we jump the Two Upper Positive Brushes (A & D), currents flow FROM DYNAMO POSITIVE BRUSH (D) TO MOTOR POSITIVE BRUSH (A)...?

WHILE, when we Jump BOTH Lower Negative Brushes (C & B) then Currents flow from MOTOR NEGATIVE BRUSH (B) TO DYNAMO NEGATIVE BRUSH C...

And WITH Both Jumpers we are creating a CURRENT FLOW which starts on Positive Dynamo Brush D, going to Positive Motor Brush A, to then go from Motor Negative Brush B and ENDING on Dynamo Negative Brush C...

Or what it would look like...(So you could see it "visually") the image below:

And of course, the center red arrows -that CROSS- in reality travel through armature coil windings like shown by the Red Circular Flows for Currents.

Am I right or wrong?
