Abstract: A battery shield designed to accommodate all vehicles that use wet cells open or sealed, and is intended to protect the eyes and face of a service individual from splashing or flying corrosive liquid from an explosion or bubbling up of the battery. This shield is composed of a clear material about two inches larger than the battery and two auxiliary steel brackets to assist in attachment. Along one edge of the long sides are three holes to accommodate three screws for attachment purposes. At the ends and along the brackets are holes for attachment of the brackets to the automobile and to the shield. The shield is composed of clear transparent non-shatterable material. The bracket is composed of metal, plastic sheet or woven material.

Abstract: A mileage improvement system for internal combustion engines that is formed by having four minimum cylinders equipped with a separate manifold and able to handle the minimum power requirements of the vehicle plus 10%. Coupled to them are four unloading cylinders larger in size and each containing an unloading valve emptying into an unvented unloading manifold.An unloading valve located in the separate unloading cylinders manifold and sensitive to the vacuum in the minimum cylinder manifold. The control valve, like a solenoid or other mechanical device, located in the unloading cylinders manifold controls a blade that shuts off the manifold's contents to the large unloading cylinders.

Abstract: A sport safety stud for use on hard or soft surfaces which is composed of a stud with a threaded boss on the bottom, a flange in the center and a spike on top, a dome-shaped piece of resilient material resting on the top of the flange. A ring of rigid material encircling the flange and bottom of the resilient material, with an inward bent lip. A disc with a center opening for the threaded boss, which places the ring in tension, holding the ring, resilient material and stud i tight combination.

Abstract: A hole drilling machine which includes a geared stationary drill frame with a guide track to which support legs are attached at either end. A drive shaft made of hollow flexible tubing driven by a motor suspended from the guide track. An adjustable swivel axel to which the drill end is mounted. The drill end is a hollow tube with openings in an end to permit streams of water to wash loose soil out of the hole and assist in the drilling process and a helical knife edge attached thereto. An angled metal piece with exit holes to permit the flow of water is attached to the working end.

Abstract: A metal fire and smoke emergency kit of generally rectangular cross section having a hinged front. Its contents enable one to extinguish a small fire, provide temporary first aid, provide emergency clothes and breathing apparatus to evacuate an area threatened by fire or fumes and attract attention enabling rescuers to locate people in danger of being trapped. Emergency instructions on the outside and inside of the hinged front are also provided. Only a fire extinguisher is mounted on the exterior of the case. The contents are protected from theft by a lead seal lock or optional room key.

Abstract: A boat trailer composed of a metal frame with cross members constructed of metal box beams or I beams, a padded board parallel to the sides of the frame and located about five inches above the wheels resting on the frame, four automotive leaf springs bent 90 degrees at one end and attached to the beams of the frame with U bolts, the unattached end being tilted slightly inward and attached with bolts to padded wooden blocks which urge the boat toward the center of the trailer.

Abstract: A leather splitting machine composed of two upright metal plates between which are attached a support roll, a cutting roll each end of which is enclosed in ball bearings which ride in a channel, and a guide roller. A knife edge rests on the cutting roll. All are adjustable to meet the needs of the thickness to be cut. A precalibrated handle along the right side is used to set the machine to the correct thickness by means of a measured guide on the right side of the machine which raises and lowers the cutting roll.

Abstract: A bed making device with a structural support base adapted to receive springs and mattress with two horizontal guide members attached at either end of the base on each side. A carrier arm is slideably positioned on each pair of guide members and contains a retractable detent pin at the top. The pin attaches to a mating opening in the bed linens and the linens are attached to the pins at the foot of the bed. A reversible electric motor with a two position foot switch, limit switch and gear driven belt drive is attached to the arms electromechanically, thereby transmitting linear direction to the mechanism. The carrier arms are horizontally propelled simultaneously forward pulling the bed linens in place. When the linens are so positioned the detent pin is retracted and the arms continue forward to a position near the head of the bed where they stop automatically.

Abstract: A contact and odor responsive device for trapping khapra beetles and their larvae in which fibrous paper or fabric strips are constructed to provide contact allowing forms containing pheromone attraction means, food attractive means and lethal means for destroying the beetles and a method of using said traps to detect and destroy the beetles and their larvae.
