An axle assembly for a vehicle includes an axle shaft having a bolt end and a lever end. The axle assembly includes a cam assembly coupled to the lever end of the axle shaft. The cam assembly includes a cam housing, a cam follower shaft coupled to the cam housing, and the cam follower shaft is located within the axle shaft. The cam follower shaft does not extend the full length of the axle shaft. The cam shaft is coupled to the cam follower shaft, and a lever is coupled to the cam assembly. The lever is rotatable from an open position to a closed position, and an angle of maximum rotation for the lever between the open position and the closed position is less than 180 degrees.

Systems and methods are disclosed herein for dressing centering a bearing compartment in a gas turbine engine. A nut may be inserted through an outer case of a gas turbine engine. The nut may be coupled to a strut which centers a bearing compartment. The nut may be rotated to achieve a desired tension on the strut to center the bearing compartment. A retaining plate comprising a collar may be positioned over the nut. A swaging tool comprising a swaging ramp may be positioned over the nut. The swaging tool may be forced against the retaining plate using a draw-in bolt. The swaging ramp may contact the collar and form indentations in the collar to lock the nut in place.

An anchor (910) for mounting to a hollow wall (W) made of friable material comprises a proximal flanged end (918) adapted to be engaged by a rotatable tool (B) to rotate the anchor (910) about a longitudinal axis (A) thereof and to cause is to gradually engage the wall (W). The anchor (910) also includes a distal end (912) adapted to cut through the wall (W) as the anchor (910) is rotated, and a shank (920) extending between the proximal and distal ends (918, 912). The shank (920) includes at least one expandable leg (924) that is in a collapsed position thereof when the anchor (910) is rotated to mount it to the wall (W) and that is located distally beyond a non visible surface of the wall (W) once the anchor (910) has been mounted to the wall and is in a first position thereof. The wall anchor (910) includes an outer thread (922) that securely engages the wall (W). A threaded fastener (B), e.g. a screw, is adapted to be introduced in the anchor (910) and to threadably engage the same distally of the leg (924) such that sufficient rotation of the threaded fastener (B) retracts the distal end (912) towards the proximal end (918) thereby causing the leg (924) to displace to a laterally expanded position thereof and to engage the non visible surface of the wall (W).

A one-piece axle comprised of three cylindrical parallel sections: a large end, a center section, and a small end concentric with the large end. The three sections are separated by an eccentric large step, and an eccentric small step. The center section is located between the two steps and is offset from the large and small ends. The center section locates and supports a front wheel of a cycle. The axle is connected to a first split axle housing and a second split axle housing located at the bottom of each of a first fork and a second fork of a cycle respectively, whereby said housings are pinched to form direct rigid and rotationally secured connections between the respective split axle housings and the large and small ends. The position of the front wheel axis of rotation relative to the forks is adjusted by rotating the axle in the split axle housings before the housings are pinched. The axle allows quick and easy adjustments of the front wheel, affecting cycle steering and handling characteristics.

A pick system includes a holder and a pick assembly. The holder includes a first end, a second end, and a bore extending between the first end and the second end and defining a longitudinal axis. The surface of the bore may be tapered so that the diameter of the bore proximate the first end is greater than the diameter of the bore proximate the second end. The pick assembly includes a shaft. The shaft is received within the bore of the holder along the longitudinal axis, and the shaft may be tapered to mate with the bore.

Adjustable portable device holder systems and methods are herein disclosed. According to one embodiment, an adjustable portable device holder includes an adjustable clamping element and a rotatable mounting element attached to the adjustable clamping element for removably securing a portable device to the adjustable portable device holder.

A socket assembly for turning a fastener with a wrench has ball mechanisms that normally engage with sides of the fastener and that can be deactivated out of engagement with the fastener by turning a collar of the socket assembly. The socket includes a socket body having a fastener receiving opening sized and shaped to engage the fastener so as to drive the fastener rotationally. At least one ball opening is provided in the fastener receiving opening adjacent the fastener when the fastener is received in the opening. A ball is provided capable of partially protruding from the ball opening with the socket in an engaged state. A ball taper insert cams against the ball to push the ball into the ball opening. A spring biases the ball taper insert so as to urge the ball into the ball opening to engage the fastener.

A firearm barrel nut assembly including barrel nut, generally cylindrical in shape with a threaded central bore, and an externally threaded locknut which is used in conjunction with the barrel nut to secure a barrel to a firearm upper receiver. The barrel nut has an integral bushing on its exterior constructed to support either the gas tube or piston of the host firearm's operating system. The barrel nut is configured so that it may be independently and non-rotationally held within a vice or other fixture during installation of the barrel and while the locknut is tightened to a preset torque to hold the barrel in place while the barrel nut is independent of the torque applied to the locknut to properly secure the barrel to the upper receiver.

An installation tool for fastening a top plate to a roof support member and other structural connections is adapted to drive threaded fasteners at a pre-established angle. The tool preferably includes a rotary driver assembly and a telescopic tube assembly. A guide head assembly is mounted adjacent the outer end of the telescopic tube assembly. Locating or reference structures function to properly precisely set the drive angle of the fastener. Various indicators mounted to the guide head indicate the flush position of a locating surface or reference structure. The flush indicators may employ a projection, a flag, an LED or an audio module.

The present disclosure includes an external fixator ring that includes a central opening, inner and outer ring surfaces and upper and lower ring surfaces. In some embodiments, one or more apertures are defined in the inner or outer surface for receiving securing devices. The apertures in the inner or outer surface are adapted to provide rigid attachment for connection struts while allowing for a range of motion between the interconnected rings. In some other embodiments, the external fixator ring further comprises angled flanges extending radially from the inner or outer surface. The angle flanges each include a mounting surface, apertures are defined in the mounting surface of the angle flanges for receiving securing devices.
