Abstract: A fire suppressant device that may be rendered automatic by exposing the device to an elevated temperature. The preferred device comprises a canister housing with a uniform cross section throughout its length, and includes a piston member disposed for sliding movement within the canister housing. The canister housing, preferably cylindrical, for containing a fire suppressant fluid, features in a preferred embodiment a nozzle mechanism that includes a cap member temporarily fixed to the spray nozzle thereof by a solder having a known melting point. Disposed between the cap member and spray nozzle is a compression spring biasing the cap member. When the canister housing is exposed to temperatures of at least the melting point of the solder, the solder melts or softens allowing the cap member to be released under the influence of the compression spring, whereby fire suppressant fluid within the canister housing is released against a fire.

Abstract: A three point hitch assembly for attachment to the rear of a powered vehicle, such as a four wheel drive vehicle, for trailing an implement. The three point hitch assembly is pivotal in a horizontal plane to allow for decreased turning radius when the implement is rendered operable, and vertically adjustable for positioning the implement. The three point hitch assembly includes a fixed planar plate mounting device for removably securing the three point hitch assembly to the rear of the powered vehicle, and a pivotal main frame mounting a rotating planar base and adapted for pivotal movement on the fixed planar plate. The pivotal main frame includes an L-shaped member, fixedly secured to the rotating planar base, a transverse arm having a pair of free ends, with each end pivotally mounting a lifting arm, where a free end of each lifting arm includes a mounting device for removably securing the implement. Additionally, there is included at least one adjustable leveling arm.
