Lincoln F. Brown invented what device for use with horses?

• A. The bridle bit
• B. The saddle horn
• C. The horseshoe
• D. The carriage whip

Answer: (A)

Understanding how riders guide horses hinges on a device that sits in the horse’s mouth and, together with the reins, translates rider signals into controlled movement. The bit is that device. It’s designed to interact with the horse’s mouth to convey cues like stop, turn, or go, making it a direct tool for guiding the animal. If Lincoln F. Brown is credited with inventing a horse-related device, this one is the best fit because it’s specifically a signaling/control instrument used in riding, rather than protective gear or tools used for other purposes. The saddle horn is part of the saddle, not a signaling device. The horseshoe protects the hoof, not guides movement. The carriage whip is used to urge motion but isn’t a mouth-based device, and it isn’t tied to a single inventor in the same way. So the bridle bit best matches the idea of a device for use with horses credited to this inventor.
