Does anyone have any specifications for the handle for the double barrel Bridgeport tire pump? I have a pump and the handle is missing. I have a lathe so I figured I could fabricate one if I had a design.
This is the type...
Thanks
Keith

Notice some of the original red paint is still on the base.

Here's mine:
If I had a drawing with some dimensions, or a sample to copy, I could make one.

A.J. “Art” Bell posted the link to the patents and there is another good photo on the thread at:

And a close up of the handle:
I’m sure someone will be able to give you better numbers to go off of. But until then, the illustration with the patent may help? While it does not show the dimensions of the handle, base, or tubes, you should be able to measure your tube and scale the measurements for the other parts. And of course it may or may not be the exact pump you have. And may or may not have the handle that was used during production. But looking at the photo of a couple of pumps it is similar.
Respectfully submitted,

Hi Keith, I've got one if you want me to take it off & mail it you so you can copy it or I can take some measurements for you.Let me know. Regards, Bob
Keith, you had better find another pump. The check valve area is broken.
Thanks for the illustration, Hap!
Is some one could provide me with some dimensions to go with it, I will be set!
I will also need dimensions of the metal pieces that go above and below the handle.

Larry is right about the broken casting. I guess you just want it for show with your car??
Hello Keith If you print this pic you should get actual size I have added the measurements ours is the early aeolus bridgeport pump it has pure brass tubes, the handle is stained very dark brown.
Hmmm...
No one told me the nuts are 1/4" x 24 thread.
Anybody have a couple?
Nuts are 1/4-28 standard SAE NF ( I just ran a thread chaser in mine)
Are the threads 1/4-24
Or are they 14-24
Not much difference between the two, but more than enough.
I found a piece of old shovel handle and based on the measurements and photos I created a handle. It still needs some sanding, but it's getting pretty close. It needs a little more massaging...
I found some #14-24 or 1/4-24 nuts in my Tveeten cabinet and made a couple of washers out of feet from discarded coil points.
I need to figure an outlet fitting. The thread looks smaller than 1/8 pipe. Since the piece is broken, the pump will not be functional, but want it to look presentable for show.

To expand on what Peter C S said, the number size machine screws are commonly available in 6, 8, and 10 sizes. Some people are familiar also with the number 4 size. Numbers 2, 3, and 5 are also used in some electronics applications, as are quite a few more small and odd sizes.
The number size also used to be commonly used into 12, 14, and rarely 16 sizes that I have seen. Ford used several number 12 and number 14 machine screws in the model T (starter Bendix cover for one, magneto magnet screws for another).
Post WWII, many of those early sizes started to really disappear. 14-24 and 1/4-24 are very close to the same, but not quite. 12-24 is also close to 1/4-24, just a bit smaller.
Common standard is 1/4-20 SAE (course) or 1/4-28 NF (fine). 1/4-24 is an old thread that you may find on some antiques. I know I have found a few.
Throw metric int the mix, and you have a real confusing mess. But also a few nuts and bolts that can be re-cut to make a nut that works well on an old odd thread shaft.
It is quite possible that you may find some pumps have one thread, and other pumps another thread count. You likely need to measure the pump you have to know what you need. The common standard today thread counts were not commonly applied until around 1910 on many things. Lots of companies were slow about adopting those standards, and some things continued to use old standards well into the 1930s. Ford himself, and his company, were early in adopting those standards. But some things, like tools may not have been held to those new standards for awhile at least.
One of the easiest ways to get an odd size nut, is to buy the odd tap from a tool supplier, and re-thread a standard close-to-size nut. Always try to enlarge the hole slightly if you have that option.
I don't have any links handy, but there are several tool suppliers that can provide odd thread count taps over the internet. Some special thread hardware can also be had.
Good luck!
Drive carefully, and enjoy, W2
Keith, the handle looks great! You are correct on the stem thread, it is 24 TPI, when I checked mine I just ran my 1/4-28 thread chaser into the nut and it zipped right through. I double checked with a thread pitch gauge and it's definitely 1/4-24, sorry about the bad info.
I'll paint the cast iron bottom Chev Orange. What about the cast iron top?
Hello Keith Ours has a red bottom and a gold top with pure brass barrels Cheers Colin
Keith, here are some photos of the top casting of my pump. It had orange paint on the lower base and brass plated steel tubes. I see no traces of paint on the top casting. I wiped it clean with solvent and scrubbed a little with a tooth brush. It may have been brass and nickel plated but I can't tell for sure. It looks like it has rusted where some sort of coating gave way,
Rich
Keith,
If you take the pump apart, you could probably weld some metal on and rebuild the outlet area. It does appear from the photos of others' pumps that the top was plated--brass or nickel. Might have depended upon the model run.
