This is a "What Is It?" Question

09/08/2011 8:15 AM

A friend found this in his uncles garage and he had worked at SD Warren paper co. maybe in the 1940's which may or may not pertain. It is an aluminum or pot metal box with a tapered cover made of wood that has 8 rows of holes with 102 per row. At each end there is a screw with a plate atached that moves back and forth about 3 inches. The over all length is 25 5/16 by 1 1/4 deep by 1 5/8 wide, the body has M639A stamped on one side and what looks like KM CO. on the other the plates on the screws have M639B stamped on them. In a couple of the holes there was a material that looks like old leather or some fiber like material. It looks like some type of press. Thanks for any input. Brian

Looks like a paper press to me that's used to squeeze out process moisture in a testbed paper product....

Whatever it is, don't let PlbMak know about it!

Estimating the diameter of the screw as being quite small; around 1/8", I would rule out the "press" idea. I think there are other parts missing. Other than that, I don't have a clue.

It may be used with air to "float" paper into or out of a machine. The screws would be a simple way to adjust air flow/pressure??????

Do a flame test on both parts or even scrapings. If it was leather you will smell it. If it was printing ink or a petroleum based product it should have a different smell. That way you can narrow your search.

My tip would be food processing with parts missing. Handling it would help. A lot of work has gone into it and the maker had other customers.

Not long and we will know, Ky.

PROCESS & QUALITY CONTROL LAB INSTRUMENT

In a paper mill where wood is used to make the pulp, by mechanical shredding and biochemical reaction a mixture of fibers is made. I keep it as simple as this to not have to describe the complete process.

To know when the "soup" is ready to pour and to spread it over the felt before pressing and calander, a know "spoonful" of material was poured into the box with the sliders on max distance, the cover was mounted and depending on the procedure in down- or up position a quality inspection was done:

1. the water content as C.Moosie pointed out.

2. The fine'ess of the pulp - the finer, the more holes were filled to the top when vertical

3. The strength of the mix what is supposed to become paper. This is related to the length of the "spaghetti" showing up.

The "leather" is dry paper pulp that hasn't been removed. It is different from the paper sheet because of the hole diameter that is bigger than the thickness of paper.

SD Warren bought our company in 1976.

To get rid of the excess of water. The system works only in a pretty small range of densities. (slurry like)

This looks like a paper machine suction box. A vacuum would normally be applied to the box to remove water from a pulp slurry mixture on an endless screen that would pass over the box. The adjustable plates are to allow for different widths of paper and not loose vacuum on the box at the edges.
