One-Piece Cuff Button: Two Faces and a V Shank Cut From One Brass Blank (Buchsbaum, 1923)
Samuel Buchsbaum of Chicago received US 1,444,023, dated 6 February 1923, for a cuff button made in one piece. A flat blank has two oval faces joined at their edges by a tongue. The tongue is bent into a V-shaped shank with a curved middle, and the faces lean in towards each other. Pockets between the shank and the faces hold the two ends of the cuff together. There is nothing to solder and nothing to come apart.
We cut it from brass sheet with a jeweller's saw, using a 1:1 template. All sizes are ours.

Cut a blank out of the paper and lay it on 0.8 mm brass sheet. Scribe round it. Saw just outside the line with a jeweller's saw, then file to the line, keeping the tongue an even 4 mm wide where it meets each face.

Grip each leg close to its face with the flat-nose pliers and fold the face back down outside the leg, so it hangs beside the leg and leans in a little, as in his Fig. 1. The narrow gap between leg and face is the pocket for the cuff. Check both faces sit level with each other.

Turn the button edgewise and pass one face through both buttonholes, turning it as it goes, as he describes. Each cuff end should sit in a pocket between a leg and its face, and the ends stay together. If it is too tight, open the faces out a little; if loose, press them in.

History and honest limits
**Samuel Buchsbaum** of Chicago, US 1,444,023, dated 6 February 1923, filed 22 August 1921. He claimed "a blank for cuff buttons comprising a sheet metal member having enlarged end members and a connecting tongue joining the adjacent edge portions of said end members". His were stamped; ours is sawn and filed. He also shows a form with square ends and a reinforced tongue (Figs. 5-6), not built here. He gives no sizes or metal: the brass, the 18 x 12 mm faces, the 4 x 18 mm tongue and the angles are ours.
