Self energized for instant application

Brake-in-Time is a self energized system that uses drive link capture technology.  With low activation force, it is easily throttle controlled for instant braking and full time chain control.  A short video of Brake-in-Time is shown at the bottom of this page.

This system can also replace band brakes resulting in a next generation saw.  Text of US Patents 6,769,187 and 8,601,919 is at http://patft.uspto.gov/

 

 

An early prototype used dual pins (arrows) to capture a drive link.  The pins are staged to insure carrier rotation to set a pin; spikes removed for clarity.  As shown in the video below, dual pins instantly stop the chain as desired for a next generation saw.

Ready to run, Brake-in-Time single pin (arrow) prototype with the clutch cover removed.  The spring loaded pivoting lever is cable connected to the throttle for braking upon throttle release. The upper hand guard (out of the picture at the top of the pivoting lever) operates in kickback to set the brake and force the throttle to idle.

In brake mode, the pin is lodged in a drive link gullet as evidenced by the lifting of the chain. This forced pivoting of the lever pulls the throttle to idle as noted by the cable slack.  Since this is a self energized system, all activation forces are easily throttle controlled.

The above videos show a dual and single pin Brake-in-Time with a cost effective kickback brake compared to a standard chainsaw. The chain stopping time, upon throttle release, is reduced by over 90% which could easily reduce or eliminate injuries.  Our Kickback brake has the added safety feature of forcing the throttle back to idle. Clutch cover removed for clarity - Brake-in-Time can easily be placed under a clutch cover.
