Description:
The specifications note German, French and Belgian patents. The specifications describe movable and fixed jaws, and various combinations of wrench, adz, hatchet, hammer, vise, and pipe-cutter assembled from the parts shown and described.

The basic wrench resembles Port's Nov. 30, 1875 patent no. 170,492.

GB-188304477 (Provisional, registered Sept. 19, 1883) may represent an attempt to secure a British patent for the tool. A further combination tool evolution which saw production as "PORT'S UNIVERSAL WRENCH" corresponds to British patent GB-189122707.
