Abstract: To obtain an elastic joint of which one end is formed by a heading process, with tooth marking in relief, provision of a toothed rivet is provided. These teeth on the rivets are such that they form cavities interspersed with teeth marked on the edge of one end of the joint. It is shown that, by acting in this way, fewer teeth are needed and a correct indexation of the rivet during its successive revolutions is ensured. A lower number of teeth is favorable to a better blockage of the elastic joint against a side plate of a vehicle chassis.

Abstract: A planetary sphere/ring gear, comprising a sphere and a ring, which are interconnected by a ball and a socket. The ball is located on the edge of a circular opening in the ring and the socket is located on the body of the sphere. Used in conjunction with this planetary sphere/ring gear is a pedal-powered three or more wheeled vehicle which comprises a chain wheel, and pedals which swivel and which swing on a cradle. An operator's seat also swings on said cradle. Even though traversing across slopes, the chain wheel, pedals and seat are in a straight-with-the-world position, which is a natural and comfortable position for pedaling. The planetary sphere/ring gear is needed in the vehicle to allow the toothed ring, with a drive chain around it, to change its axis to line up with the drive wheel, as it swivels and swings.

Abstract: A safety device may be used to provide separation in the event of a side impact collision. The device may be used in a utility pole guy wire system, interposed between the guy wire and the ground anchor. The device operates in bending. A lateral force of sufficient magnitude applied to the device by the errant vehicle causes a rod within the device to break in tension, even though the tensile strength of the rod may be greater than that of the guy wire. In operation, certain massive portions of the device are tied safely to the ground, while other portions are pulled over the moving vehicle by the tension of the guy wire. The invention may be designed to tolerate axial loads, but to fail reliably when a side force exceeds a desired threshold. When installed in series with a utility pole guy wire, the invention will withstand all normal tensile and incidental loads, and will release when subjected to a high side force as from an automobile impact.

Abstract: A fastener is provided for splicing end portions of conveyor belts together with the fastener having a bolt with a pilot or lead-in portion that provides improved threading of a nut thereto and makes installation of the fasteners on the belt ends faster and easier. The pilot of the bolt is longer than the beveled conical tip portion of prior bolts so that nuts received thereon will stay substantially aligned with the axis of the shank. In this manner, threading of the nut to the bolt shank is easier in terms of avoiding cross-threading problems. Also, as the pilot portion of the shank is free of any threads, the installation of the bolt onto the belt ends can be done more quickly with less resistance during the insertion process.
