Pivotally Linked Speed Loader for Revolver Cylinders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Revolvers require frequent reloading due to their limited shot capacity, and existing speed-loading devices either require excessive force, are bulky and expensive, or fail to facilitate simultaneous and accurate loading of cartridges into multiple chambers with one hand.
Innovation Solution
A speed-loading mechanism with pivotally linked cartridge housings that can be stored linearly and collapsed into a circular configuration for quick, simultaneous reloading of all cartridges into a revolver's cylinder, utilizing retaining springs and release buttons for easy one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If strip type loading devices are used to enable linear storage and one-handed operation, then ease of operation is improved, but a large amount of force must be exerted to rotate adjacent links causing loading difficulty
Solution Approach 1:
The device transitions from a static linear configuration to a dynamic circular configuration during operation. The links are designed to pivot and rotate automatically when the device is collapsed into its circular form, eliminating the need for manual rotation of individual links during loading. This dynamic transformation resolves the contradiction by making the device easy to operate with one hand while eliminating the excessive force requirement.
Solution Approach 2:
The device collapses from a linear arrangement into a circular configuration that matches the curvature of the revolver cylinder chambers. This curved/spherical arrangement allows the cartridge engaging portions to align naturally with the chambers, eliminating lateral force components that would otherwise cause incorrect seating or ejection of cartridges. The circular form factor enables simultaneous loading without requiring excessive rotational force.
2Quantity of substance
If strip type loaders with offset axes are used to secure cartridges, then cartridge storage is enabled, but lateral force components cause cartridges to sit incorrectly or eject from chambers
Solution Approach 1:
The device is designed to collapse into a circular configuration where the cartridge engaging portions are arranged in a circle that matches the chamber arrangement in the revolver cylinder. This eliminates offset axes and lateral force components, ensuring cartridges are inserted straight into the chambers without causing them to sit incorrectly or eject. The circular geometry ensures proper alignment and reliable cartridge seating.
3Productivity
If solid cylindrical cartridge loaders are used to enable simultaneous loading of all rounds, then productivity is improved, but the devices are expensive and bulky
Solution Approach 1:
The device is segmented into multiple individual links, each designed to hold and release a single cartridge. These segmented links are connected in a chain that can be collapsed into a circular form. This segmentation allows the device to achieve simultaneous loading capability like solid cylindrical loaders while maintaining a simpler, more compact structure that is less expensive to manufacture and easier to store when not in use.
Solution Approach 2:
The device uses dynamic linkages that allow the segmented structure to transform from a linear storage configuration to a circular loading configuration. This dynamic capability enables the device to achieve simultaneous loading of all rounds like solid cylindrical loaders, but with the added benefit of being collapsible and easier to conceal carry, thereby reducing device complexity and cost.
4Ease of operation
If strip loaders are designed to allow cartridge release during link rotation, then cartridge loading is enabled, but the inability to automatically assume and lock into rolled configuration prevents accurate matching with revolver chambers
Solution Approach 1:
The device automatically assumes a circular configuration when collapsed, where the cartridge engaging portions are precisely positioned to match the chamber arrangement in the revolver cylinder. This geometric design ensures accurate alignment without requiring manual adjustment or complex locking mechanisms. The circular form factor inherently provides the precise measurement and alignment needed for accurate cartridge insertion into each chamber.
Solution Approach 2:
The device is designed to automatically assume and lock into its circular configuration through its own structural design, without requiring external tools or complex mechanisms. The links self-align and self-lock into the correct positions when the device is collapsed, ensuring precise alignment with the revolver chambers. This self-service mechanism maintains ease of operation while achieving high measurement precision for accurate cartridge placement.

AI summary
A speed loader for a revolver having a series of pivotally linked cartridge housings which are collapsible into a secured circular arrangement having an equivalent number of cartridge housings and matching the number of cylinders in a revolver. When in the collapsed position the speed loader allows for simultaneous re-loading of all cylinders with one hand. The cartridge housings are pivotally linked such that they are extendible into a straight line for safe and secure storage in a pocket.
