Three US Machine Tool Safety Patents

Flesh-Sensing Safety Technology

US Patent 8,082,825 introduces "flesh-sensing" safety for dangerous machine tools. The technology provides an improved health and safety system that includes blade guard, proximity detector, emergency motor braking, anti-kickback, adapters, plus sawdust extraction. View Patent

Black Box Plug & Play Device

US Patent 8,336,432 for the "Black Box" compatible with millions of existing dangerous machine tools to monitor machine tool safety operations and bring the tool to a rapid stop in less than one second. The machine will not be damaged and may be restarted immediately after the operator has learned of an unsafe operation. View Patent

Data Logging 5G – IoT

US Patent 10,684,601 advances the above technologies into the realm of 5G IoT - Machine control and data logging station for monitoring both safety features and machine tool utilization history without requiring any human intervention. View Patent

Whirlwind Tool Patented Safety Technology

Black Box Flesh Sensing Safety Device

Black Box Flesh Sensing Saw Safety Stop

Senses when fingers are in danger and STOPS the saw blade in 1/8 OF A SECOND!

Developed by veteran woodworker David Butler, the patented Whirlwind Tool BLACK BOX table saw emergency blade brake is a simple bolt-on/removable device which can be easily and inexpensively incorporated into use with millions of existing saws and machine tools. The prototypes showcased on this site differ from all previous table saw blade guards and emergency blade brakes, with a built-in "electronic fence" blade enclosure.

Metal Cutting

Metal Cutting and Fabrication

The BLACK BOX has been used for metal cutting and fabrication. With a simple modification to our woodworking guards we are able to cut metal on a band saw and two types of our table saws. In addition to the revolutionary, new BLACK BOX system showcased here, Whirlwind health and safety technologies have been successfully implemented using the Makita bench top, Delta, Powermatic and Rigid saws.

Data Logging

Data Logging

Many types of machine tools pose consequential danger to operators that are either unaware of safe practices, not sufficiently experienced in the machine’s use, or who have developed generally unsafe operating practices. The table saw is a prime example of such machines, as reflected by their grim safety record over the past century. Safety features such as blade guards in place can now be monitored continuously along with details of each operating cycle together with time stamp.

Whirlwind Tool Hot Dog Test

The Hotdog Test

Thousands have watched our 'Hot Dog' test showing the successful stop of a dangerous table saw equipped with Whirlwind Tool's patented 'flesh-sensing' machine tool safety technology. Not a mark on the weiner and the power tool was returned to service immediately after with no damage.
