  • Patent number: 6460282
    Abstract: My invention is a new and improved hammer mechanism which reduces the strength of the hammer mainspring without also reducing the hammer's strike force. My invention comprises a link mechanism integrally assembled to the hammer of a firearm. The link mechanism moves at a positive velocity relative to the hammer as the hammer itself moves from the “cocked” position to the striking position. Both the hammer and the link mechanism are biased into the striking position by the hammer mainspring with a section of the link mechanism protruding from the front surface of the hammer and impacting the firing element of the firearm or primer. The link mechanism thus impacts the firing element or primer at a velocity and force roughly equal to the aggregate velocities and forces of the hammer and the link mechanism.

  • Patent number: 6408556
    Abstract: A breech block firearm safety device for the prevention of injury to children having unauthorized access to loaded firearms. This device will also protect gun owners from injury due to mishandling or the dropping a loaded weapon. The safety device utilizes a two piece blocking assembly having a breech member and a bore member. The breech member is inserted into the breech just as you would insert a live round to arm a weapon. The bore member is inserted into the muzzle of the firearm and screw connected to the breech member using special tooling. The chamber blocking assembly can be easily extracted but the overall length is such that the end of the bore member remains in the breech making ejection impossible. The assembly can only be returned to the breech, making manual or automatic loading of live ammunition impossible. When the above safety device is installed in a revolver the overall length prevents the rotation of the cylinder and prevents the loading of live ammunition into firing position.

  • Patent number: 6076885
    Abstract: A speaker support bar supports a pair of speakers above a vehicle headliner. The speaker support bar is positioned vertically above the headliner, and thus the uniform appearance of the headliner is preserved. The speaker support bar extends between lateral support ends which transfer the weight of the speakers to the headliner over a wide area, and near the vehicle frame. Thus, the headliner is able to support the weight of the speakers. The invention also facilitates the pre-assembly of the headliner and its sound system prior to attachment of the headliner to the vehicle.

  • Patent number: 5934698
    Abstract: A hitch support mechanism is positionable in a vertical direction to adjust for the hitch height of a trailing vehicle. The hitch support may be adapted to be removably attachable to a receiver fixed to a vehicle. The hitch support may be configured as a four-bar linkage in which a fixed link is secured by a trunnion to the receiver of a towing vehicle. A translating link may support directly attachment of a hitch, such as a ball hitch. Two rotating links, spaced from one another may extend parallel to one another. The rotating links connect the fixed link to the translating link. The rotating links each rotate about a respective axle, remaining parallel with respect to one another. An adjustment mechanism may fix the relative position of the translating link with respect to the fixed link. A system of apertures and a pin may provide a very compact adjustment mechanism, resulting in a light weight and compact envelope for the hitch support.

  • Patent number: 5816353
    Abstract: In a fuel cut controller wherein fuel supply is stopped to some cylinders when there is a fuel cut request, an ordinary fuel cut mode and a multi-cylinder fuel cut mode are set. When the ordinary fuel cut mode has continued for a predetermined time, fuel cut is performed in an equal or larger number of cylinders in the multi-cylinder fuel cut mode, and the engine output torque therefore decreases further. At the same time, due to the increase in cylinders where fuel supply is stopped, the amount of fresh air flowing from these cylinders to a catalytic converter increases, and the amount of unburned fuel flowing into the converter from the cylinders where fuel supply is performed decreases. As a result, heat due to reaction of unburned fuel in the converter decreases, and the increasing amount of fresh air cools the converter, so temperature rise of the converter is suppressed.

  • Patent number: 5810417
    Abstract: The automatic seats in a vehicle are designed to minimize the seriousness of car-crash injuries during a frontal collision. When the vehicle collides against the other vehicle or any other stationary objects at a relative velocity of 40 Km/h or up, the backrest is pushed to recline backward by the action of the springs together with various mechanisms especially designed. Spring of either torsion type or tension type is used. The collision results in pulling the upper part of the body of the driver or the occupants fastened by the designed safety-belts to recline backwards. Thus, the pelvis, the chest and the head of an occupant sitting on this automatic safety car seat are moved away to the farmost and thus, can avoid striking with the deforming frontal parts of the car intruding by the frontal collision. The chest injuries and the brain damage can then be effectively avoided.
