Tripod Traverse Stop Clamp for Machine Gun Sweep Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traverse stop devices for machine gun tripods are cumbersome and time-consuming to install, lacking definitive stopping positions, which complicates the restriction of pivot sweep angle during firing.
Innovation Solution
A traverse stop clamp with an open ring member, shift member, handle, spring pin, and locking nut is designed to be easily adjustable and lockable on the traverse bar of a tripod, allowing quick and secure position adjustments without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional traverse stop devices are used, then the sweep angle can be restricted, but the installation becomes cumbersome and time-consuming
Solution Approach 1:
The traverse stop device is divided into separate modular components: a clamp body, an adjustment mechanism with screw and nut, and a stop member. This segmentation allows for easier installation and adjustment compared to conventional monolithic devices, reducing installation time while maintaining reliable sweep angle restriction.
Solution Approach 2:
The device incorporates an adjustable mechanism that allows the stop member position to be dynamically changed along the traverse bar. The screw and nut adjustment system enables quick repositioning of the stop member to different angular positions, making the device adaptable to various sweep angle requirements without time-consuming reinstallation.
2Reliability
If conventional traverse stop devices are used, then the sweep angle can be restricted, but definitive stopping positions cannot be achieved
Solution Approach 1:
The device replaces imprecise mechanical stop methods (such as hose clamps or duct tape) with a precision adjustment mechanism. The screw and nut system provides controlled, measurable adjustments, while the stop member engages with the traverse bar at precise angular positions, achieving definitive stopping positions with high accuracy.
Solution Approach 2:
The adjustment mechanism is designed to be self-adjusting and self-locking. The screw and nut combination allows the operator to easily position the stop member at desired angles, and the mechanism maintains the position without external intervention, ensuring consistent and accurate stopping positions throughout operation.
3Reliability
If conventional traverse stop devices are used, then the sweep angle can be restricted, but the installation is cumbersome
Solution Approach 1:
The device is constructed from modular segments that can be independently assembled on the traverse bar. The clamp body, adjustment mechanism, and stop member are separate components that can be installed in a systematic sequence, reducing the complexity and effort required compared to conventional integrated devices.
Solution Approach 2:
The adjustable design allows the device to be quickly configured for different applications. The screw and nut mechanism enables easy repositioning of the stop member without requiring disassembly or complex manipulation, making the device simple to operate and install while maintaining reliable sweep angle restriction.

AI summary
A traverse stop clamp is provided for restricting sweep of a machine gun mounted on a tripod. The stop clamp is installable on a traverse bar connecting to rear legs of the tripod, the traverse bar having an inverse U-shape cross-section that form edges at ends of the U-shape. The stop clamp includes an open ring member, a shift member, a handle, a spring pin and a locking nut. The open ring member has a C-shaped ring with an interrupted circumferential outer periphery and an inner periphery with channels for receiving the edges of the traverse bar. The outer periphery has first and second ring ends separated by an adjustable gap. The open ring member further includes first and second tabs disposed to extend radially outward from the first and second ends. These first and second tabs respectively have first and second through-holes. The shift member has a tang and a shaft at respectively first and second shifter ends. The receiver has a third through-hole, and the shaft has a threaded terminus. The tang and shaft pass respectively through the first and second through-holes. The handle has a lever and a clevis head with coaxial fourth through-holes. The head has a cam separating a lock clevis face and a release clevis face. The lock clevis face engages the tang in response to the lever being adjacent the outer periphery. The release clevis face engages the tang in response to pulling the lever away from the outer periphery. The handle pivots at the fourth-through-holes to widen the gap between the tabs. The spring pin passes through the fourth and third through-holes to connect the tang and the clevis head pivotably together. The threaded lock nut attaches to the threaded terminus to engage the second tab.
