Welcome to the forum Sara,
To me, it looks like an adjustable router template guide, but not sure how those small pieces in the corners might effect the cut. Maybe a door template guide?

I ran across the following. Are the corner pieces removable? It looks to have been designed to automatically square itself up no matter what size you make it.

I'm recalling some old time cabinets that had a groove cut in a shape like that. This would allow you to do that on any size drawer front, for example. Can't find anything else about this jig. If the corner pieces come out, or are replaceable with other shapes.

I found this pix. We need a real old-timer for this.

It's hard to tell what the dimensions are, but it's possible that assuming the router rides against the inner rails, with a round ~6" base plate, it might not contact the corner pieces when going around the corner.

This was all I was able to find on this item

That looks pretty close, @pal

It looks like one, possibly 2 of the inside corner pieces have been damaged. It also looks like they are part of the large corner piece because that would be the only way to make this fully adjustable.

Depending on how the large corner pieces are built there might be a way to remove the damaged portion of the corner pieces and mount new inside corners for the router collar to ride on during use. This would also lend itself to making special pieces for the inside corners so you would not be held to the rounded corners like it was designed.

Reading through the patent gave me sore eyes, but it boils down to what I thought it might be. Here is the meat and potatoes of the patent application:

"This invention relates to a routing template and more particularly to a routing template for use in routing various design configurations in flat panels such as cabinet doors and drawer fronts or the like.

In custom cabinet work, it has been a problem to provide a simple routing template which may readily be securely engaged with flat panel or flat panels of various sizes for the purpose of routing various ornamental designs therein.

Heretofore, various templates have been made for routing designs in panels of a given size, but it has necessary to tool up templates on a custom basis for each given panel, and thus, it has been prohibitive for cabinet makers or other craftsmen to provide rounded ornamental in various panels of various sizes due to the cost of such custom work."

One of the features of this device is that it can be affixed to the panel so it doesn't move while routing the groove. You fit it to one corner of the workpiece, then slide the opposite side to the opposite corner, then pull the other sides so they fit the corners. It stays parallel no matter what size rectangle the piece is. As someone mentioned, the rounded corner pieces are so the router base fits. The small pieces in the corners seem to be fixed.

A very long time ago, far far away, I remember having or seeing a dresser with drawers with this kind of groove, in fact, the same shape. Looked for a picture of the result, but can't find one. It's a little like doing an inlay, in fact you could probably do that with the right bit.

I can visualise what that template will produce and how it will work, it's a pity some pieces are damaged but you could probably get them repaired, depending on the size it's a template for either drawer fronts or doors, possibly both if big enough, it should give a raised panel outline, edges can be to any specification, eg roundover or bevelled, the size of the raised panel will depend on the guide plate or bearing guide in the router, the initial cut will be like "levelling" the piece, further decoration is up to the user

I'm from the UK and it resembles a variable jig guide made by a UK company called Trend, however the Trend guide does not have corner pieces like that, their guide is completely flat on top, depending on the radius of the curve, which I'll presume are removable and interchangeable with others then it's probably an adjustable template guide for round cornered squares or rectangles, by interchangeable I mean they can be replaced by larger or smaller pieces

Without the little corner pieces, it would probably come in handy for making router table holes. My mom had kitchen cabinets with veneered particle board doors. They had a routed design like in the pic. The design was painted black and kinda tinted along its edges. They looked quite nice considering the material used. I wonder if that rig was for something like that.

My mistake, I hadn't noticed the internal corner pieces, however they do appear to be removable, it also appears that as in my previous post on this subject that the external corner pieces can be moved and replaced as required

It seems to me that the bigger curves are just to allow for the baseplate of the router to get by. A bushing or bearing would ride on the interior of the adjustable rectangle but the baseplate would ride on the bars. The little corner inserts could make a shape like the drawing I posted. The thumbscrews in the large curves are the locks.

I see where you're coming from on the internal corners, I'd also say that the external ones could give a different shape depending on the size of the router baseplate, from the photos shown it also appears that the outside corners can be adjusted, any basic rectangle/square template will give you the shape with rounded corners, but utilising the external corners shown would allow some adjustment in the corner radius, unless the external shapes are just there as reinforcement and for no other purpose, thanks TenGees your idea is food for thought, I'm off to work at the Edinburgh Fringe soon so probably will not be able to comment or view a lot of things on the forum
