Here's an excellently designed set of accessory brake shoes. I have been running these for several years on our 1915 roadster and they work great. They give even pressure over the full surface of the brake drums.

Tell us how you find the original patents so quickly?
I tried searching the USPTO site and am lucky if I can find anything closely related and finally gave up.
For example can you find the original patent for the Trembler Coil?

Hi Ron
I just stumble around looking thru a few hundred patents
until I find one that looks like its somewhat believable.

Well really I start with “Goof-le” Patent Search to see if
they got the spelling close enough to find something easily
(or at all), and if that’s a no show, I go to the USPTO site
try to figure out what the guy assigned to research the patent
had for lunch so I can guess at the classification he hid the dam
thing in and if that doesn’t turn up any . . . .

I guess what I’m trying to say is the easy ones I do with Google,
and the rest require a high degree of stubbornness (I call that
“positive thinking") and some outside the box thinking as well.

If your browser (or add on) supports .gif files you can an idea of a
USPTO patent search with the short search I setup on this page . .

Click on the patent number (16 on the list), and then click on
“Images” in the center of the page.

Art
Ps. I see Google strikes again – Your listing above shows the patent
was issued 44 years before it was applied for. Nobody’s perfect <@^@>

Looks like a forerunner of the Model A brake. Works on the same principle except that the A is a little more developed.

It appears the patent records were scanned and used an optical character recognition program. Many of the dates, pattentee name and titles are misspelled.

I agree with that Ron - scanning and ocr'ing 7 million
patents is bound to have a few errors. Great idea though.

David
Here is the patent filed in Great Britain for your 2005 photo.
I finally figured out that the pat number in your photo was
111598 and not 10598 as it first appeared.

Patent Number GB111598
Application Date Feb 27, 1917
Complete Accepted Dec 6, 1917

Thanks Art!

I agree with Royce - some of the vendors should do these.

I also agree these would be an excellent candidate for reproducing. None of the other shoes you can now buy for your T have as much drum contact when applied as these puppies do. As we all know, going in a model T is never the problem, it's the stopping that counts! Any extra stopping power you have on board is a BIG plus. I would buy a set for each of my three other T's if they were offered for sale.

Me too. Looks like they would be much better than the cast iron ones that are available now. Dave

So, help me get my mind wrapped around these, because they look like a great idea. Are these for really positive hand-brake action, or would these be rigged up as a service brake somehow??

I have always been leery of the cast iron shoes, but I thought the vendors now sell lined shoes for small drums. No?

Yes, you can now get lined shoes for the small drums, but these adjustable would make them work better as an emergence brake in case of failure in the service brake.
