In my quest to fill in my Ellis style adjustable wrench collection I have discovered that there are possibly at least 6 different variations that Ellis manufactured over the years. 2 patents are attributed to the wrench, November 3, 1903 patent not located and May 17, 1904, patent 759,869 that depicts a leaf style spring and other differences in the wrench design. The wrenches are marked with the November 3, 1903 date. The different styles are non-swivel head, swivel head, flat or nut jaws, pipe jaws and 2 different swivel latch designs, neither match the patent drawing. The attached pictures are of 2, 8 inch versions that are part of my collection. One is the earlier design swivel latch and one with the later design latch. The later design has a screw in latch release handle as the earlier design the handle is part of the latch release paw part. The earlier swivel latch example has one of the sections broken out that locks the swivel head in position. I have 2 - 6 inch, 2 - 8 inch and 1 - 18 inch version in my collection. I am on the lookout for a 10 inch and a 12 inch version. I would be interested in hearing about any other variations that are out there.
