Patent for a new and improved device for weaning calves. This design is "to be attached to the central cartilage of the calf's nose . . . with sharp points that come against the cow's bag when the calf attempts to suck; and the invention consists in attaching the parts . . . together like a pivot, forming a part of one of the points and adapting them to be held closed by means of a small screw, whereby the device is rendered very cheap, yet effective and reliable" (lines 15-25).
