Abstract: A sprayer system for reducing the need to manually create pressure within a portable spray unit. The inventive device includes a reservoir, a manual pump, an electric motor, a battery electrically connected to the electric motor, an air compressor mechanically connected to the electric motor, a valve stem within the reservoir, and a safety valve within the reservoir. The valve stem can be utilized by a user to connect a conventional air tank thereto for inserting high amounts of air pressure directly into the reservoir without requiring the use of the manual pump or electric pump. If a power switch is closed, the electric motor will operate the air compressor whenever the air pressure within the reservoir drops below a predetermined level. When the air pressure within the reservoir rises above a predetermined level, the electric motor is deactivated thereby preventing the reservoir from becoming over-pressurized. The manual pump may be utilized when the electric pump fails or the battery becomes discharged.

Abstract: The invention comprises a mobile frame and a floatation frame having a tractor pivotally mounted to its rearward end. Rolling members are mounted along the bottom of the floatation frame and tractor so that they may roll along the mobile frame. The floatation frame has floats along its rearward end and the tractor has a brake member to lock the tractor at a location on the mobile frame with a floatation member connected to the brake member for actuating the brake member when the floatation member is immersed in water by the floatation member floating upward, whereby the mobile frame may be rolled into the water to immerse its rearward end, and the brake member may be released to allow the tractor and floatation frame to roll rearward on the mobile frame into the water until the floatation member of the brake member is immersed and floats upward to lock the brake member, thereby locking the floatation frame and tractor rearward on the mobile frame with the rear end of the floatation frame afloat on the water.

Abstract: The invention comprises an adjustable support for support elongated miniature objects such as the fuselage or wing of an airplane or hull of a boat laterally of its length. The supports have their one ends attached to a horizontal surface, with the support each having a post fixed to their other end and a movable support having a post to be movable on the adjustable support to a position adjacent the lateral side of the miniature object opposite the fixed post to support the lateral sides of the object. A flexible string may be extended beneath the object and connected to the posts to support the bottom of the object in continuous close proximity.

Abstract: The invention comprises a holder or support for the outlet plug of an electric heater for an engine of a vehicle. The holder has a pair of parallel plates adapted to be fixed on opposite sides of a front bumper of the vehicle. A pivotally mounted plate is pivotally mounted to one of the parallel plates which may be pivoted to lock it in a selected position depending upon the configuration of the front portions of the vehicle. The pivotally mounted plate has a hole therethrough to receive the prongs of the outlet plug of the heater. The pivotally mounted plate also has clamping means to clamp the plug to the plate when the plug is mounted in the hole in the plate with the prongs projecting forward to receive an extension cord plug to provide current to the heater.
