This isn’t latch-hooking, but the Argyll Ali piqued my interest when I saw it.

Made of metal with blue painted wooden handle, the Argyll Ali is often called an "egg whisk" because turning the handle action causes the needle to rise and fall. This curiosity resembles an old-fashioned egg beater or hand drill, but with a rising and falling rug punch needle in place of a whisk/beater. A thin strips of fabric or wool from a ball was threaded through the eye in the needle. The rug backing was placed on a traditional rug frame and the rug-maker wound the handle while moving the Argyll Ali across the backing. When the handle was turned, the needle rose and fell, piercing the backing fabric and leaving a loop beneath the fabric when the needle was withdrawn.

While I couldn’t find patent information specifically for the “Argyll Ali” brand, I found information about "egg whisk" style rug punches in general.
