A tag that was on this said it was an old roofing tool, is it?




Is this used in repairing bike tires?



What the heck is this thing? While turning it goes one way then reverses itself...




Another what the heck for me.

The C clamp thing is for tire patching, It clamped the patch which was attached to a metal piece with a material that you lit with a match,  The heat vulcanized the patch to the tube with heat.  Called Hot Patch.
The crank thing is for seating in engine valves. There was a suction cup on the end of the shaft that you placed on the top of the valve, you placed some valve seating compound under the valve face and with the valve in place in the seat you could crank the gizmo and it would lap the valve to the seat.
The other had clamp is for valve springs.  Hope some this makes some sence to you.

On the first one, is there a hole in the square end of that?   It looks like the result of a design excercise and 15 minutes at the forge.    We used to hot patch inner tubes, light the sulphur mixture, let it cook off, then wait til it was cool to remove the clamp.  Where did  you find all these goodies?

The Valve spring compressor is for side valve engines ( flathead).It looks to be from late twentys to mid 30's. Chrysler used side valve engines up to 1960.
The valve grinder could have had a flat steel blade held in with a cotter pin , used on valves with a slot in head.It also could have used a suction cup.
Looks to be from late 30's

No hole, its a solid piece of steel. This stuff was in my box from the rt.11 crawl.

The first thing looks like a hand made clinch block for clinching horseshoe nails when shoeing the dang beasts.

How bout the 3rd pic anyone ever use one of them?
When you turn the handle it spins clockwise for a second then counter-clockwise
then back to clockwise and keeps on switching directions. I thought it was some
kind of hand cranked drill but the changing directions has me all screwed up.

I just found info on it and would have never guessed valve grinder.

Looks very much like a clinch block.  It's especially like the form issued to farriers and artificers during the Civil War.

Your Valve lapper should be labeled, mine is (The name is drawing a blank at the moment)

So did Rambler, up into the mid 60s.  Amazing to think about, now - a nice engine, if you're not concerned about emissions.  But emissions controls pretty well killed flathead engines - too hard to do on that engine type.

They are a bit more sophisticated than just that.

Have another close look at the action to see that the reverse is less than the forward sweep so that there is rotation to the lapping.

Your right, tinkered with it awhile ago, but still don't see any writing on it.
