New invention available for sale or license: Double Vice Grips:
Every handyman, metal fabrication shop worker, machinist, field or shop mechanic has experienced this at one time or another. You need to drill a hole in a small piece of steel. Without going to expensive and cumbersome holding devices that are secured to the drill press base, the vise-grip is the tool of choice. However, to securely hold a small item in place with one pair of vise-grips is a very dicey proposition. The torque created by the drill bit will almost always twist the material being drilled out of the grip of the vise-grips. This creates a situation that is both unsafe and inconvenient for the person trying to drill said hole.
The single vise-grip configuration to hold a work piece such as the one pictured will provide about 30 ft. lbs. of resistance to the torque caused by the drill bit before grip is lost. The Double Vise-Grip Configuration with the pin and receiver pictured will provide 130 ft. lbs. of resistance to the torque caused by the drill bit before grip is lost. This results in a much safer and easier way to get this type of work done. The vise-grips are coupled together only when needed for the extra holding power. At any other time the vise-grips function as they normally do (separately or together). Every handyman, machinist, field mechanic etc. has a couple of pairs of vise-grips. Why not have the extra gripping capabilities for virtually the same price, as the cost to manufacture the tool with this option is minimal.
Here's the main benefit of the Double Vise-Grips:
|1. Single set of locking pliers. 25 - 28 lbs. of torque must be applied before the grip on the disk is lost.|
|2. Two sets of locking pliers. 60 - 62 lbs. of torque must be applied before the grip on the disk is lost.||
|3. Two sets of locking pliers joined by a pin and receiver at the jaw pivot point. As a result, 130 - 135 lbs. of torque must be applied before the grip on the disk is lost.||
1. What is it?
A device designed to securely hold small items in place for the purpose of drilling or grinding.
2. Who would use it?
Handymen, machine shops, fabricating shops, field and shop mechanics, oil field operations, anywhere locking pliers are presently used, but with greatly increased holding power.
3. How will it be used?
It will be used in situations where an object must be securely, safely and movably controlled by a person rather than a machine.
4. How does it work?
By joining the locking pliers at the center pivoting jaw pin, the twisting force exerted on the object being held is transferred from one pair of locking pliers to the other. This causes one pair of locking pliers to pull on said object, and the other pair of locking pliers to push on same. A straight pull or push on a purchase such as this is much more effective than a grip that tries to prevent a twisting motion. The portable application of his tool, through the use of two locking pliers joined by a pin and receiver greatly increases the ability to get a firm and safe grip on any small object.
The inventor is looking to
license the Double Vice Grips
rather than manufacture it himself it himself.
