1901 Monarch cushion frame roadster

[dnc1]

Perhaps a small nylon or rubber bush, similar to a motorcycle shock absorber would use?

Not being sure what surfaces the ''rubber plug'' may encounter ...
a top washer and a bottom washer may provide a bit o' mercy
to the plug while it is being asked to do a job of dampening.

We are asking that a rubber plug accept that it's new job of
''dampening''. And if it does ... it's girth is under force of constant
change (ouch) ... the very least we could do is to provide somewhat
of a protective ceiling and floor for the little plug ...

Without top ands bottom washers ... that little plug may run into
surfaces that are uneven ... that may influence the function / life
of the plug itself.

Consider a technology that does not always consider all .that it could ......

There MAY have been cushion-frame machines built without benefit
of a ''hinge-feature'' of sorts. That is ... a cushion frame fitted without
a way for the rear triangle to ''flex''.

Oh --- those poor chainstays.

But not on your machine !! It has been fitted not only with a rear shock-
absorbing device .. but also a built-in technology to keep that rear triangle
in unstressed geometry ... as it is being used.

These last three illustrations were originally provided by CABE member... @fordsnake. Thank you, Carlton.

Yes that makes a great deal of sense. I thought that maybe they were original equipment but they would certainly stabilize a rubber or neoprene plug.
In addition to the leaf spring the lower stays also pivot. It works beautifully and smoothly without a squeak!
Thanks for posting the original literature!

Doood ... I don't care who's peepin' that machine ...

Thanks Patric!

There’s only one bike that I won’t ride and it’s the National Racer. If I ever find a replacement set of those very delicate racing spokes for it, it would be ridden at least one time!

What size are those spokes? If I could find some I'd gladly donate them just to see that National taken on the track!
That's another beauty too.

Thanks.
They are like 19 gauge, just on the front wheel.
Often mistaken for piano wire.

Wow, that is thin.
I know people custom make spokes for veteran machines over here. I'm guessing there may be 'Wheelmen' members over your side of the pond who do similar stuff.
Nipples would have to be custom-made too.
You could always build up a racing wheelset with spokes of a different size. A fun, sometimes frustrating, but ultimately rewarding and satisfying experience.
I'll be building a set for my National soon, admittedly not as rare a beast as yours (it's a 1911 Model 132) but I'm so looking forward to riding it, hopefully this year too!

I had to extend and make room for the belt drive for my Hygenic Cushion Frame
for my 1903 Model 35, E R Thomas motorcyle
Had a guy make me new springs for the extra length and my weight. all he needed to know was out side dynamiter length and travel.
and only charged me $35.00.

I’m in for a pair of springs....

 

[David Brown]

Paul It is that rear cushion fork the piece you got from me?Spring look just like the ones I had made. Only I would think your is longer. You can use that spring on Pierce bikes also just work the threaded bung out of top and bottom of the Pierce spring and with a little work put the bung in the new spring
