Abstract: A lock coupling between two mechanical components and presenting: at least one pair of coupling elements, each of which presents an “L”-shape and protrudes from a first mechanical component; and at least one pair of tracks, each of which is made through a second mechanical component, presents the shape of an arc of circumference, ends with a flared inlet opening, and is engaged in use by a coupling element; each track presents a dimension so as to prevent the axial removal of the coupling element along its entire length except for an inlet opening at which the coupling element can be axially removed.

Abstract: A pneumatic coupling is provided. The pneumatic coupling is configured to couple a plurality of pneumatic lines together. According to the preferred embodiment of the present disclosure, the pneumatic coupling includes first and second housings and a plurality of fittings sized to receive the pneumatic lines.

Abstract: A stabilizer elbow lock that prevents a seal between a stabilizer elbow and a coupler valve from being broken by engaging at least a portion of the stabilizer elbow and by engaging at least a portion of the coupler valve. In an alternative embodiment, one or more adapters are provided that interface between the lock and the coupler valve and/or interface between the lock and the elbow.

Abstract: A multi-part STORZ type coupling comprises a pair of similar and complementary coupling units. Each unit comprises assembled inner and outer annular parts which are threaded together and fixedly attached. Each inner annular part has a pair of similar spaced forwardly projecting lugs at a front-end portion and each lug has a radially outwardly projecting ear at its free end portion. Each outer annular part has a diametrically enlarged front-end portion which accommodates an annular groove opening radially inwardly. Circumaxially spaced forwardly open notches permit the lugs of a complementary coupling unit to be entered rearwardly through the notches into the groove. When the lugs have been so entered and rotated to an assembled position the parts of the coupling may be fixedly attached to each other.

Abstract: A quick disconnect asexual locking hose coupling is provided having a spring biased coaxial sleeve with a locking projection and a sealing means having an internal gland for use with universal type hose couplings typically found in pneumatic service applications. The locking hose coupling provides enhanced safety, better sealing and ease of use over typical universal hose couplings while retaining the advantages of robustness, versatility, convenience and compatibility with the most numerous type of coupling in current use.

Abstract: A coupling half designed to mate with an identical coupling half to form a coupling for interconnecting sections of hose or the like, has a tubular body having at one end a projecting tooth and a complementary socket arrangement constituted by a plurality of uniformly spaced arcuate connector teeth axially outstanding from the tubular body and terminating in a radially inwardly directed arcuate protrusion, a plurality of radially outwardly directed arcuate ribs circumferentially aligned with the teeth, and a plurality of tooth entrance ways located circumferentially between each of the ribs and each of the teeth, a resiliently biased detent locking device in the body biased towards an advanced position, and an annular detent unlocking ring angularly rotatable on the body and resiliently biased in one direct ion of rotation to an inoperative position and being angularly movable in the opposite direction to an active position wherein it engages the detent locking means to retract it away from the advanced posit

Abstract: The present invention entails a hose coupling assembly having a pivotally mounted locking lever for engaging and locking against a cam lock. The hose clamping assembly including a pair of rotating and mating locking collars with each locking collar having a series of circumferentially spaced lugs formed about the outer surface thereof. The locking lever referred to above is integrally formed with a selected lug on each locking collar. The mounting lug includes a transverse cavity formed through the lug and mounted within the lug cavity is a pivot pin that is supported about opposite ends by the lug structure itself. The locking lever is in turn pivotally mounted on the pivot pin and is spring biased to assume a locked position.

Abstract: A multiple ply label has an extension that includes a bar code symbol and the extension is folded under the label ply when the label is attached to an article for the purpose of protecting the bar code symbol. Another embodiment of the multiple ply label has a cutout portion that allows a bar code symbol to be positioned so as to be partially covered by an overlying ply when the label is attached to an article for the purpose of protecting one portion of the bar code symbol while exposing the other portion of the symbol. The overlying layers or plies of the multiple ply label can be removed at successive stations while protecting the bar code symbol.

Abstract: A swivel gladhand for vehicle air brake systems which includes a continuously torsioned body portion which when not in use is automatically urged to a position wherein the outlet opening therein is seated against a stop member which seals the outlet opening therein and which also includes a selectively movable locking arm which is operable to cam the body portion against the stop member to thereby positively secure the body in sealed engagement with the stop member to prevent the loss of air pressure therethrough when the gladhand is not in use.

Abstract: The present invention relates to a high impact hose coupling having a hollow body constructed of plastic, a helical restriction means to hold the hose end within the coupling body, a double locking means for locking coupling halves together, and a static electric conducting gasket to allow the conduction of static electricity within the coupling.
