Aircraft Jacks
A jack for servicing the landing wheels of aircraft in which a scissor jack is provided with an adaptor to fit the underside of aircraft and is so oriented that it extends equally to either side of the jack. A selected end of the adaptor is used to engage the aircraft landing gear making it possible to place either side of the jack closely adjacent a landing wheel at either sideof an aircraft.

Air Impact Wrenches
An impact wrench for using fastening or unfastening fasteners comprises a cylindrical rotor coupled to a motor shaft, said cylindrical rotor including a projection on its inner surface, the projection having a circumferential width and an axial length; an anvil coupled to said cylindrical rotor, the anvil including a hammer member capable of rocking therein,the hammer member being engageable with said projection; a springloaded pusher for urging said hammer member towards said projection, wherein a spring support slides either on a deep cam face or a shallow cam face both produced on said inner surface of the cylindrical rotor, thereby allowing said spring to become compressed or relaxed against said hammer member.

Air Drills
An air drillincludes a body having a grip portion having an air supply passage and an air exhaust passage formed therein, a trigger portion formed above the grip portion and supporting a trigger, and a cylinder portion formed above the trigger portion and accommodating an air motor. A reverse valve is disposed within the cylinder portion in order to switch the direction of rotation of the air motor between forwardand reverse directions. Two reverse levers are disposed in an upper portion of the reverse valve and slidably accommodated in two slit-shaped openings, respectively, which are formed in a grip-portion-side end of the cylinder portion.

Air Regulators
A single stage regulator is disclosed wherein a cartridge valve, and built in accumulator configuration are utilized to regulate an input or supplypressure such as about 5,000 PSI, to an output or delivery pressure range from about 50 to about 150 PSI. The single stage regulator can be used in the construction and mechanical assembly industries. The regulator can power such devices as pneumatic nailing equipment, impact wenches, and other air driven devices.

Battery Chargers
A battery charger includes a first charger for providing afirst battery charging current and a second charger for providing a second battery charging current. A switch is provided for manually actuating the second charger. A timer times the second charger cycle. The timer is used to initiate the discontinuation of operation of the second charger. When the second charger is operating, the timer is inhibited from being reset. When the first chargerdiscontinues supplying a charging current, the battery charger is conditioned to again permit actuation of the switch to reset the timer and allow operation of the second charger.

Bearing Separators
An angular contact roller bearing has a sheet metal separator guiding rollers revolving on inclined axes in an orbital movement around the longitudinal axis of the bearing. The sheet metal separator is madefrom a ladder shaped strip of sheet metal with the cross bars in an angular orientation which is rolled to an annular form with axially spaced cylindrical end rings of equal diameter. The cross bars may be configured to provide roller retainment in either or both radial directions as exemplified by the three embodiments disclosed. In one embodiment one of the cylindrical end rings cooperates withone bearing race to provide a unit handled subassembly with retained rollers. As disclosed in the specification, the cylindrical end rings may also be used to center the separator from one of the races if such a feature is desired.
