Friend Jerry and I are leaving Wednesday for the Northwest Vintage Speedsters 2014 Labour Day Endurance Run (driving the '24 Speedster 900 miles each way for the 200 mile event).
As usual a few days before leaving on a big trip we dream up some improvement to build and install on the car — this year it's a foot-feed throttle.
I know Langs and the others sell them, but there is no time to order and anyway it would be more fun to make our own setup.
I would really appreciate any photos and suggestions members could post about their foot throttles. I have some miscellaneous linkage bits and an old exhaust cutout pedal on hand as a starting point.
You have to use the correct terminology. Folks who grew up in the T era called it a foot feed. How do I know? I heard them call it that.
Yep... It would called a foot feed.
You're going backwards, Chris!
Foot feeds are evil. Ask Toyota.
Have a good trip.
Chris, this is one occasion where RHD is a blessing. Our foot feeds can be directly connected to a pedal with a solid rod straight to the carburettor.
I took a Texas T parts foot feed off the Tudor sedan I brought in from the USA. What an abortion of an idea, not enhanced by the clumsy installation. If I had to have a foot feed on a LHD car, it would be by cable rather than any linkage assembly. Much simpler and more easily fitted.
Hope this helps,
Allan from down under.
Model A gas pedal linkage is a good start. Seen it done.
The Red "C" period accessory accelerator looks possible to copy fairly easy: http://www.mtfca.com/discus/messages/179374/227116.html?1312347647
Here are some other threads on this topic:
A Williams accelerator would also be possible to adopt to most any carb setup, but I guess you'll have to fabricate the pedal too..
Thanks everyone for the info and links (and, of course, the vocabulary lesson and warning!) Now that I think of it, I may have a Model A *FOOT FEED* kicking around somewhere.
Here are three photos I snapped last summer when Dick & Trudy Retger's 'Round the World '15 touring was in Edmonton...
built this one from 5/16 rod
used Mdl A linkage rod,made a new rod coming thru engine,drilled end,installed 1/16 cable,for hand feed,the arm I bolted to carb I cut off Mdl A dist timing adv.
Chris, I have an original, here's some pics and a sketch w/dimensions:
Thanks, Ken — exactly what I was hoping for!
Love your profile pic by the way... what's the story behind it?
Ken and Chris,
That is the classic mechanism for the foot feed adaptation. Not shown is the flexible link (chain) that goes to the hand throttle lever which allows dual control.
Ken & Chris
This is the chain assembly that John was referring to, it allows you to use you'r hand throttle or the foot feed.
Just put another reverse pedal to the right of the brake pedal, that'll really mess up the heads of everybody at the car show that looks in to see the tree pedals.
Ken, on the part that gets the 90% bend that connects to the bolt of water inlet .
What is the TOTAL length of the 3/4 X 1/8 bar
Thank you, great pictures and sketch
Lorenzo, I guess I missed the up-down dimension on my sketch, sorry about that.
The up-down part is 3-1/8", works out to about 6-3/4" overall.
Ken ,I made one ,the hole for the pedal is not there yet I have to see what size pedal rod to use
Thank you Ken
