Help identifying this press fictures?

I have a bunch of this spring fixtures for a press i just picked up.. does anyone know any info on these? Or a name for them? Can't seen to find them online. Thanks.

They don't look like a common catalog part. My guess is they were used as part strippers. In this particular case, I'd wager a nickel the round hole was clamped to a boss or a cylindrical part of the punch holder and the oblong hole is simply there to let the punch(es) through. When the press cycles open, the springs would shove the part off the punches. Is there a set-screw in one of the three sides you don't show in that photo?
Thing is, most dies have custom-made strippers. There are catalogs full of die springs (which you can use to make strippers), guides and guide bushings, and pre-made die sets. But not much in the way of pre-built strippers.
What kind of press do you have? Is it some sort of ironworker or punching bear? A open back inclined (OBI) press? A straight frame press?
Did it come with a bunch of unitized tooling (individual C-frame die sets)? Do these fixtures fit the unitized tooling?

It is a roper whitney kick press. I have for boxes of these stripers and the dies that go with them. I am not even sure if the would work for this specific machine. I got the kick press more fore metal shaping projects and these were included. I added some more photos. It does have a pat. Number

Patent no supplied......read the patent and you will know what they are for (maybe)

I tried to look it up on Google. Nothing came up for me.

I spent quite a few hours as a young teen inserting knurled-body SCRs into holes in heat sinks for a small motor control company outside Indianapolis, using a very similar kickpress. They are quite handy for jobs that fit.

They look like a stripper for a type of modular stamping die called a "Whistler".

Agreed. SB Whistler's website doesn't provide much detail (or a catalog). It looks like they have moved over to urethane-based strippers from metal spring strippers, but at at least one of the old photos on the Adjustable Dies page has a stripper with four metal springs like the boxes full the OP has.
So, strippers for modular dies.

In a former life I had the misfortune of trying to work on/change over one of these evil contraptions.

It quickly became the apprentice's job to do. As it taught them how NOT to design a stamping die.

Very cheaply made and very hard to work on.

Pretty much the "Yugo" of stamping die design and function.

It gets you from A to B put don't hit any potholes.

Thanks for the help guys. Very informative.

This is looks to be the patent: https://patentimages.storage.googleapis.com/c1/ed/ba/1ca453006ddae1/US1986036.pdf
Looks like the inventor was a Lawrence V Whistler of Kenmore New York, Assigned to SB Whistler and Sons.
