摘要： A power tool with a two-part housing has a drive motor with a pinion gear on the motor shaft. A plastic cylindrical ring gear is fixed to the motor in coaxial surrounding relationship with the pinion gear and has attachment lugs which fit between the two parts of the tool housing and are fixedly secured to each. A plastic gear carrier frame is insert molded on a splined end of a metal output shaft and is receivable within the ring gear and has radial slots for respectively receiving pins which respectively rotatably mount three planet gears in meshing engagement with the pinion gear and the ring gear. The carrier frame has a hollow stub shaft portion which receives the pinion gear therethrough, the stub shaft portion having an elastomeric O-ring seated in a circumferential groove therein for press-fitting a ball bearing thereon, the ball bearing being in turn press-fitted in a seat in the ring gear to support the planet gear assembly.

摘要： A wheeled carriage has a chassis with a plurality of swivel casters, and a locking assembly actuated by a foot pedal located along the front of the carriage. Pushing down on the foot pedal rotates a cam that engages a cam follower on a "T" bar frame supporting two locking rings which respectively overlie two of the caster wheels to move the rings into a locking position in engagement with the wheels to lock the wheels and the casters in any position. The cam follower surface includes a ramp portion engageable by the cam for driving the rings to their locking position and a horizontal latch portion engageable by the cam in its "overcenter" position for holding the rings in their locking position. A lifter bar is engageable by the user's foot to rotate the cam back off the follower and permit the rings to resiliently return to their release position. The cam and follower surfaces are so arranged that a limited rotation of the cam through less than about 25 degrees is sufficient to move the assembly between its release and locking configurations so that the locking assembly can be used where only a few inches of clearance beneath the chassis is available.

摘要： A cabinet has a plurality of drawers, each provided with a latch hook at its rear end which is receivable through a corresponding one of a plurality of apertures in a lock bar at the rear of the cabinet which vertically reciprocates between a lowered position interfering with the latch hooks to prevent opening of the drawers and a raised position accommodating free movement of the latch hooks through the apertures to permit opening of the drawers. A lock at the front of the cabinet rotates an elongated rod, the rear end of which engages a coupling bracket on the lock bar to lift it part way to its raised position, at the same time moving a sliding portion of the coupling bracket into position for engagement with a pivoting crank coupled to the rear end of a second spring-biased and push button-actuated rod. When the push button is depressed, the crank is pivoted to lift the lock bar the rest of the way to its raised position.

摘要： A force-multiplying device includes a base or stationary structure and three levers all pivotally mounted on the base and each having a force input end and a force output end and being arranged in a folded configuration such that each lever extends from the force input and to the force output end thereof in a direction generally opposite to that of adjacent levers in the series. The pivot point of each lever is closer to its force output end than to its force input end so that the force delivered at the output end is greater than that applied at the input end. The base and the output lever may operate as a pair of opposed jaws, each carrying a removable force application device for different applications such as cutting, crimping, punching, lifting and spreading. The input lever and the base structure may be configured as handles of a hand-operated tool and the levers may be arranged to either open or close the jaws in response to movement of the handles together.

摘要： A tray for a set of sockets of varying diameters includes an elongated, open-top, trapezoidal receptacle with upstanding end walls each having an opening therein in the shape of a 270.degree. sector of a circle, with the ends of each sector defining stop surfaces. A bail retainer has an elongated flat bight and depending end portions which respectively extend along the outside of the end walls, and each provided with an inwardly projecting rectangular tab which extends into the asociated opening to form a chord thereof. The retainer is pivotal between a retaining position wherein the bight closely overlies the receptacle to retain the sockets therein and a position alongside the receptacle permitting removal of the sockets from the receptacle, the pivotal movement being limited by the stop surfaces of the openings. An elongated flange depends from one side wall of the receptacle to facilitate hanging on an associated support, such as a tool chest.
