The patent document describes a Holder for Driving-Reins invented by Albert Mendenhall of Oskaloosa, Iowa.
The patent number is 637,811, and it was granted on November 28, 1899.
Purpose of the Invention
The object of the invention is to provide a simple, strong, durable, and efficient device that can be detachably fastened to the top edge of the dasher (dashboard) of a buggy or carriage. Its primary function is to allow a person in the vehicle to readily detachably fasten driving-reins thereto, preventing them from falling to the ground where they could be trampled, soiled, or cause accidents.
Key Components and Operation
The holder is essentially a spring-actuated clamp designed to grip the reins against a fixed surface.
The Frame (A)
- It has a longitudinal slot in its bottom part that allows it to straddle the top edge of a dasher.
- It is secured to the dasher using set-screws (b).
- One end has an integral vertical extension (C) with a vertical slot (g) and a stop (o).
- The other end has an inclined extension (A’) that serves as a guide for easily slipping the reins in and out.
The Clamp (D)
- The clamp holds the reins against the top face of the frame.
- It is pivotally connected to the vertical extension (C) of the frame by a screw-bolt (f).
- The screw-bolt extends through a bore in the clamp and the vertical slot (g) in the frame, allowing the clamp’s height to be adjusted to suit different rein thicknesses.
The Spring Mechanism
- A coil-spring (m) is placed on a nut (h) on the screw-bolt.
- The spring engages an extension (D’) on the clamp.
- The outer end of the spring is adjustably connected to the part C by being inserted into one of a plurality of holes (n). Changing the hole regulates the tension of the spring.
- The spring’s tension is what normally forces the clamp down onto the reins, securely fastening them.
