An aircraft wing includes a rib attached by a joint to a tubular spar that varies in cross sectional shape during flight. The joint includes a ring attached to the tubular spar, and pivot pins connecting the ring with the rib. The pivot pins allow relative movement between the rib and the tubular spar as the tubular spar varies in cross sectional shape.

A pin clamp is provided, comprising a housing having a bore extending therethrough, therein defining an axis. A shaft in sliding engagement with at least a first portion of the bore comprises an axial hole. A piston coupled to the shaft is in sliding engagement with a second portion of the bore. A clevis has a clevis base and two clevis prongs extending along the axis. The clevis base an axial hole and first and second radial clevis holes, wherein the first and second radial clevis holes are opposed to one another by 90-degrees. The axial hole accepts the shaft, and the clevis base is coupled to the shaft in one of four 90-degree-opposed positions by a screw passing through one of the first and second radial clevis holes and the axial hole. Each clevis prong has a radial prong hole. A locating pin has a mounting portion configured to be coupled to the housing in one of the four 90-degree-opposed positions. A clevis pin selectively couples a tang end of a clamping arm to the clevis through radial prong holes of the clevis prongs. The clamping arm extends and retracts based on a position of the shaft and an engagement between an actuator pin coupled to the housing and a slot in the clamping arm.

A combination includes a shackle with a pin and a locking ring. The shackle body has a closed geometry defining a primary opening therethrough and includes a first side member with a first aperture, a second side member spaced apart from the first side member and having a second aperture. The second aperture is positioned opposite from and aligned with the first aperture. End portions extend between and connect the first side member and the second side member. A pin has a body portion extending between a head portion and a tip portion. The pin defines an annular slot extending at least partially around the pin. An expandable retaining ring is configured to be installed on the pin and occupy the annular slot, where the retaining ring prevents removal of the pin from the shackle body when the pin is installed in the shackle body.

A coupling pin (10) comprising a carriage member (12) and a riding member (14) longitudinally slidable over the carriage member. The carriage member and riding member being mutually inclined longitudinally, and together complementing each other to form a uniform pin. The pin may be inserted into an aperture such that the carriage member is first disposed therein, and a force subsequently applied to the riding member causing it to move longitudinally with respect to the carriage member, into a load-bearing position.

A method of modifying a hand-held tool which having a stationary handle actuated by a movable handle connected to a movable tool jaw by a connection linkage, the method including removing the moving handle and the stationary handle. A pneumatic actuator with a piston rod is added. The connection linkage is modified to extend between the piston rod and the movable tool jaw. A trigger is added between the pneumatic actuator and a source of pressurized gas.

A cleaning apparatus includes an elongate rod defined by a proximal end portion having a first linkage member and an opposed distal end portion. The first linkage member is pivotally coupled to a second linkage member of a cleaning head. There is a biasing assembly that is coupled to the elongate rod and to the cleaning head, which tensions the cleaning head to a maximum pivotal excursion relative to the cleaning rod.

A retaining formation defined on a brake lever of an air disc brake includes a push fit/snap fit connection for releasably securing a push rod to a brake lever. The retaining formation can include a pinned connection and a ball and socket joint, and a main axis of the pinned connection is coincident with a center of rotation of the ball and socket joint. The retaining formation can include a concave formation on one of the push rod and the brake lever and a corresponding convex formation on the other of the push rod and the brake lever. The concave formation at least partially surrounds the convex formation to prevent axial separation of the push rod and the brake lever. A method of assembling a brake subassembly includes the steps of assembling a push rod and a brake lever including a retaining formation such that at least a portion of the retaining formation deforms during assembly and resiles when the push rod is assembled to the brake lever to provide a snap fit connection therebetween. Another method of manufacturing a retaining formation includes the steps of providing one of a push rod and a brake lever with a concave formation, providing the other of the push rod and the brake lever with a convex formation able to receive the concave formation, assembling the concave formation and the convex formation, mechanically working the one of the push rod and the brake lever with the concave formation such that the concave formation at least partially surrounds the convex formation to prevent axial separation of the push rod and the brake lever.
