Continuing with the subject of joints in barn looms – here are some pics from a few of my own.
I have looms with different styles of joints, and some that are exactly alike.
The joints, among other features help to identify a region or style of loom which can also help identify the looms purpose.
So, if we had a sense that a loom was of Irish or Scottish origin ( meaning that weavers who immigrated from those countries made their tools here ) we know that those trained in those countries often wove linen and / or coverlets and carpeting. Their looms would have had featureds designed for such. While joints alone won’t identify those origins, combined with other features often we can narrow down a group and from their, a place, date and type of textile made.
Some looms were for blankets, some for linen and so on. Most looms could weave anything, it was the weaver who specialized, but the tool more often than not reflected that in some way.
For your reference:
Here are photos of five of my own looms.
English style looms tend to have joints that are flush, Scandinavian style looms tend to have the slot and key style joint that extends beyond the frame. German and dutch looms tend to have joints that extend beyond the loom frame in varying degrees.
Extending very slightly.
This also shows an example of a tenon that was dovetailed as well.
I am not the final authority on this subject, and welcome comments and more info if any readers know something that differs from what I am offering.
Have a great weekend!
