摘要： The invention is a light, portable, miniaturized tire inflator adapted to fit in a limited space, such as in a tire well for a deflated, space-saving tire in a trunk of an automobile, and adapted to be carried or held in one hand. The tire inflator includes a metal, preferably steel pressure cannister comprising in one embodiment a pressure vessel and a pressure head cap assembly, a pyrotechnic material in the pressure vessel, an ignitor mechanism and a nozzle in the head cap assembly, an internal insulation liner for said pressure cannister to reduce the temperature level of the cannister to a level acceptable to an external insulation, such as plastic foam or paper, of about 350.degree. F, and a resilient insert for example rubber, in the nozzle end to mate and thread in one embodiment, with the metal tire valve threads, and prevent cross threading, while providing a seal with the tire valve for inflation of the tire. The rubber insert also allows the tire inflator simply to be pushed on the valve and form the required seal, rather than threaded thereto, due to the resilient nature of the rubber.

摘要： An improved ratcheting pipe wrench which includes a first toothed jaw formed on a first member and a second toothed jaw rotatably carried by a second member provided with an elongated handle portion. The first member has a shank portion which is slidably receivable in a guide way formed in the second member. The guide way is configured to provide clearance to the shank portion of the first member so as to permit both longitudinal and pivotal, or up and down rocking movement of the first member relative to the second member. With this construction the jaws of the wrench can readily be separated to accommodate a pipe, nut or bar (work piece) of various sizes. Further, with work piece in position between the toothed jaws, pressure exerted on the handle portion of the second member will tend to increasingly tighten the jaws about the work piece to provide a positive gripping action. Conversely, release of pressure on the handle portion will cause the jaws to loosen so that the wrench can readily be ratcheted to a new gripping position.

摘要： A nozzle for use with a light, portable, miniaturized tire inflator. A resilient insert in the well of the nozzle enables it to be connected directly to the metal thread of a tire valve either by mating the insert with the screw thread or by pushing the insert onto the screw thread. The resilient nature of the insert prevents cross threading of the nozzle with the screw thread. During the inflation of the tire, the inflating gas exerts a force on the insert, thus causing it to compress. Such compression enables the insert to hold the screw thread and to provide a seal during the transference of the inflating gas without requiring any mechanical assistance to maintain proper contact with the valve.

摘要： An internal pipe wrench adapted to engage the inner walls of a pipe for applying torque thereto. The wrench comprises a rotatable mandrel which is generally triangular in cross-section and three cooperating gripping jaws movable into gripping engagement with the pipe upon rotation of the mandrel. The gripping jaws are retained in operable proximity with the mandrel by means of a yieldably resilient rubber or plastic material and are uniformly configured so that upon rotation of the mandrel in either direction, the leading edge of the gripping jaws will move into positive gripping engagement with the inner walls of the pipe.

摘要： The invention is a light, portable, miniaturized tire inflator adapted to fit in a limited space, such as in a tire well for a deflated, space-saving tire in a trunk of an automobile, and adapted to be carried or held in one hand. The tire inflator includes: a pyrotechnic material, an ignitor mechanism, a pressure vessel, and a nozzle. The pyrotechnic material generates an inflating gas upon burning to inflate a tire without a source of stored fluid. The ignitor mechanism is located adjacent to the pyrotechnic material to ignite and cause the pyrotechnic material to burn. The pressure vessel holds the pyrotechnic material. The pressure vessel has a tire end and a pyrotechnic end. The nozzle is mounted on the tire end of the pressure vessel. The nozzle is adapted to be connected directly to a valve of the tire. The nozzle includes a combined connection for the tire valve and initator for convening the chain reaction which will automatically result in the inflation of the tire on connection of the inflator to the tire.
