Some Sort of Small Drill and Taps

[FireFlowerPower]

I have 2 old manual hand drills but I dont know what they would be used for.
by the looks of the base they clamped on to somthing.
The handles have a tap on one end and a flat screw driver head on the other.
As you can see from the images one still has the drill in it and can be set to drill to different depths.

I'm wondering what they would be used for.

Yep, what he said.

As was stated they look like small screw type arbor presses. The tap/screwdriver handle must have a purpose. Can you remove the "drill bit" and show us? Also tell us any markings that are on them. Look under the base. Also where did you obtain these? They may have a single special purpose.

ADDED: Here is a link on how to make a homeade screw press. Notice the similarities. http://www.vintageprojects.com/machine-shop/press.pdf

Here is a pic of the drill bit.
As for markings, theres nothing.

The one with out a drill bit does have a chuck for a drill bit to slide into.
I dont think there presses.

The machine in the first pics looks like it could be a type of drill press IF the shaft turns independently from the threaded pieces. The second one appears to be a type of press being the shaft is threaded and cannot move independent of the framework.

Yes its a drill bit allright. I guess they are very slow hand turning drills. The problem is that you show a high speed modern drill bit.

this pieces look like front end tools...
1st, reamer for kingpins, 2nd. press for installing.

I think you are right pippin! I was thinking ball joint press when I first saw them, but king pin sounds very much right. These are most likely homemade to hence no markings. I have always admired ingenuity.

I really don't think they are homemade, the frames are cast,
can't tell from the photos what metal they are,
but you can see the casting marks on the shoulders of the mystery tool in this photo.
I could be wrong, is making your own cast tools common?

Also I don't think the end of the handle is a tap, I think it is a thread cleaner.

 

[Bigcypresshunter]

Maybe it would help telling us how you obtained these.

Vintage bit sharpening jig?

Does it have a modern drill chuck? ...or the older brace type?

 

[FireFlowerPower]

I got it from my mother-in-law's old second-hand store that she now uses for storage.
She does not remember where she got it from.

Its not a modern drill chuck so it must be the brace type.

The only other info I think that might be usful is to tell you I'm in Oklahoma.
Maybe somthing to do with all the oil rigs in this area?

Does the drill chuck look like these? or is it just a set screw? Can you change bit sizes or only one size? I cant see in the pic. The type of drill chuck used on the old braces was invented I think around 1885. I dont know when they switched to the modern type. My Dad used old braces in the 1950's as a carpenter. So if its this type of drill chuck it would be 1890's-1950's. Someone was using a modern high speed drill bit.

Guessing also.
I think king pins were mostly a slip fit (before rust anyway).

I'm guessin' it's alot older and a device for making nuts, the old square style.
You might look into the chuck to see if what looks like a screw driver blade (on the tap) doesn't fit into a slot to prevent the tap from slipping during use.
Also the double collar looks as intended to apply pressure to the bit or tap while boring/tapping.
I agree the drill bit is modern, I've seen bits with the same 'screw driver' end as the tap. I think that may have been lost and replaced with the modern.
The other one looks like part of the tool that dowels the ends of spokes for wooden wagon and carriage wheels.

Not a bad guess. Or even for drilling and threading the end of a metal strap for a bolt.

I was thinking along the lines of a chain-breaker, as I have seen similar ones for motorcycles and drive chains on farm equipment . . . but the threading ability isn't needed there.

 

[JamesE]

Those I have repaired, reamed installed were a very good slip fit after ream, and held in with lock bolt that went in a notch on the side of the pin in a hole through the axle boss/bore. old chevy, old econolines, some others but it's a good 30 years.
A & T's I think used similar, but don't know. Might take a press or torch to get old ones out, not to put back in.
Not to imply that I know how every king pin ever made was assembled.

Def Not a frt end tool.
avg king pin dia. is 11/16 in & over upto 1 9/16 for off highway str8 axles.
neither of those tools are sturdy enough for reaming or pressing king pins.
I have done my share.
I would agree with the chain breaker for top tool & pin press for rejoining the chain 2nd pic.

I would have to agree with gold. Even though I havent worked on kingpins, I can see the supposed reamer drill looks to be only about a 1/4 inch diameter at most. Thats got to be way way too small. I didnt realize myself how small these things really are. Its easier to visualize with a known object in the picture.

I have an ATC chainbreaker and it fits in the palm of my hand but this may be an older larger version.

The lower:
How about olddddd (gunsmith tool?) hand held lathe with a tool on an extensoin rod holding, a bore reamer, or breech rim relief might be cut, threads seem to be to fine for a simple press.
I still like the upper one making nuts or threaded rod ends like were used as struts on old farm implements and corn cribs. Flatten the end of a rod on the anvil, secure it with the lower thumb screw, move the collar up and lock, and it will apply pressure to the bit or tap as the T handle is turned down.
Doesn't really seem sturdy enogh for working iron though. How about a primer or fuse extraction set for artillery.
It's still a cross between an elephant and a rhino to me!
