These are adapted to engage one face 33 of a support 30, in an aperture 31 of which the receptacle is mounted. In use, the bight portion 14 engages the other face 32. A third element 20 is disposed at the opposite end of the second element 16 from the bight portion 14 and has a flexible barb portion 23 arranged to flex on insertion of the receptacle in the aperture and to engage the other face after insertion in order to retain the receptacle in the aperture.

Abstract: An axial locking device has locking balls which engage in a groove in a male member to lock the male member to a female member. To effect locking, a first axial movement of the male member causes it to abut an end surface on a slider and pushes slider teeth against rotor teeth, and a return movement of the male member allows the slider and rotor to return, pushed by a spring. In this way, the rotor is caused to rotate and its internal cam surface moves the locking balls. To reduce the number of parts and simplify manufacture, retaining teeth are formed by U-shaped clips on the housing of the female member, and act to prevent rotation of the slider during its axial movement, and to prevent rotation of the rotor until the rotor teeth have cleared the retaining teeth, causing a click or snap action. During the return movement of the slider and rotor, the rotor teeth cam over the ends of the retaining teeth and continue to rotate the rotor in the same direction.

Abstract: An arresting device for force-transmitting fixing of two relatively movable parts, particularly for cutting angle or cutting depth adjustment of electric hand saws, the arresting device has a pin having a radially extending pressing surface for pressing against one of the parts, a clamping element having a pressing surface for pressing against another of the parts and arranged on the pin so that by a relative turning of the clamping element and the pin the pressing surfaces are moved toward one another for producing a clamping and from one another for releasing the clamping. The clamping element is formed as a hand lever having a clamping sleeve and a lever arm extending from the clamping sleeve. The clamping sleeve is turnably arranged on the pin and has a clamping collar extending over the lever arm and provided with a ring-shaped end surface forming the pressing surface of the clamping element.

Abstract: A coupling device which can be used as a clasp to connect the ends of chains, bracelets, necklaces or other articles of jewelry has a male component including a shank which can be inserted into the passage of a tubular or disc-shaped female component whereby the shoulders at the rear side of the front end portion of the shank engage adjacent shoulders of the female component to prevent unintentional extraction of the shank. The shank or the female component has one or more resilient sections which can be engaged and deformed by one or more stressing portions of the other component in response to rotation of at least one component relative to the other component to thus ensure that the size of the passage is temporarily increased or the dimensions of the front end portion of the shank are reduced in order to permit extraction of the shank from the female component.

Abstract: A fastener having five parts. A flexible material such as canvas is apertured at a point of connection and a first washer having a boss axially receives the apertures so that the material overlies the washer. The material is held in sandwiched relation between the first washer and a second washer, both of which having gripping surfaces that engage the material. The washers are pressed downwardly by a knob. The knob has a depending central post that releasably engages a lock member that is in turn releasably engaged by a base member that is secured to a support surface. The lock member has a boss part with an annular step that supports the first washer. A pair of flanges extend from a bottom end of the lock member and are engaged by overhanging walls formed in the base member when the knob is turned.

Abstract: A quick-action fastener for connecting two plates (III) and (IV) with a resilient gasket (V) interposed therebetween, all three being perforated by a throughgoing hole, comprises a bolt (I) passing through this hole and engaging with a bore (24) in a socket (II) which is rigidly fastened to the plate (III). A helical groove (14) is cut into the end of the bolt, which has a lead angle not exceeding 15.degree., and which engages with a protrusion (42) inwardly projecting from the bore (24) of the socket. Friction between the protrusion (42) and the wall of the helical groove (14) is strong enough to hold the bolt in position and to clamp the two plates together, owing to the tension of the resilient gasket.

The C-shaped webs (3) are integrally connected to the base portion (2) in extension of a thin walled portions (2") closer to the stud-retaining structure (4). The slot (8) extends from one side of the receptacle across the central axis thereof, so that the opposing thin walled portions (2,2") of the base on opposite sides of the cross-cut slot (8) can engage opposite surfaces of the support member at an aperture in which the receptacle is to be mounted.

Abstract: A spindle nut remains attached to a dye spindle for repeated dye operations and includes radially projecting cam surfaces for successively guiding and locking a lock ring against outward movement relative to the spindle nut at the beginning of successive dye operations. A pressure plate engages the outermost yarn package on the dye spindle and a tube is fixed to the pressure plate and extends outwardly about the spindle toward the lock ring at the beginning of each dye operation, terminating in spaced relation from the lock ring. The pressure obtained during each successive dye operation moves the pressure plate outwardly until the tube engages the lock ring to hold the yarn packages on the spindle during dyeing.

Abstract: A receptacle (20) for a stud (30) is mounted in a rectangular aperture (38) in a member (34). The receptacle has a housing (22) with a base (40) and flat legs (42, 44) and is held on the member (34) by being gripped between flanges (46, 48) on the legs and a non-circular element (28). Each of the legs has a side flange (54) on each side and diametrically opposite one of the said flanges have a slot (55). The pair of opposed flanges on each side of the receptacle define an elongate slot between them in which the non-circular element is free to move after rotation from a position in which it is held within the transverse slot (55).
