"Vintage Machinery" entry for Du Bois & Beugler
Beugler went on to be a designer and patenter of barrel making machinery for E. & B. Holmes, Buffalo, NY.

Our invention consists of the taper bushing slit in two or more sections at the large end the full length of the hub in which it is to be used, leaving sufficient length on the same, not parted by the slitting, to form a nut or screw.

When the bushing is made with the screw on its end, a nut is fitted for the purpose of drawing the bushing into the hub by screwing it on the bushing against the end of the hub, thereby drawing the bushing into the hub, and contracting the bushing onto the shaft, and keying it firmly in the position desired.
