Locking electrical connector

Abstract: This invention relates to a locking electrical connector which is particularly adapted for lanyard release. The connector has a first contact with an annular inner projection. This contact is adapted for expansion to enlarge the diameter of the inner projection when a mating second contact or jack is being inserted or removed from the contact. A locking collar is mounted for movement between a first position over the first contact, preventing the expansion thereof, and a second position in which the collar does not inhibit the expansion of the contact. The locking collar is normally biased to the first position. The second contact or jack has an annular outer groove and is dimensioned to be seated in the first contact with the annular projection of the first contact in the annular groove of the second contact when the contacts are fully mated. For a preferred embodiment, a lanyard is secured to the locking collar and is adapted, when a suitable axial force is applied to it, to move the locking collar from the first to the second position.

Telescoping strut construction

Abstract: An extendable and collapsible telescoping strut construction comprising inner and outer tubular members adapted to be slidably received in one another. The inner member is provided with rolled-in portions constituting annular locking grooves, respectively. The outer member has radially extending slots to receive locking dogs which are advanceable toward the inner member so as to engage various annular grooves thereof one at a time and thus hold the inner member in predetermined, fixed positions with respect to the outer member. The latter further carries a spring-biased, slidable collar member which retains the locking dogs in positions of engagement with any one of the annular grooves. Positive, cooperable locking means on the collar member and on the outer tubular member are provided for retaining these two parts in a predetermined, fixed position against accidental bumping or jarring, whereby the locking dogs are firmly held in their advanced, locked positions. The arrangement is such that the spring automatically advances the collar member to its locked position with respect to the outer tubular member as soon as the collar member is released.

Rotational collar alignment device

Abstract: A self-contained fluorescent lamp fixture for installation in a conventional incandescent lamp socket which permits selective adjustment of the fluorescent lamp fixture through a substantial arc and which readily facilitates retention of the fixture in the adjusted position. The new fixture includes a body cover which is adapted to receive a conventional fluorescent tube as well as the other components required to make the tube operational. This cover includes a pair of opposed, generally centrally located arcuate slots and is mounted between upper and lower fixture collars by a pair of threaded fasteners. The fasteners pass between the collars through the arcuate slots whereby the cover may be selectively rotated in a plane normal to the axis of the fixture. The upper collar includes means for threadedly mounting the entire fluorescent fixture in an incandescent type lamp socket. A generally flat, compressible member is received between the lower collar and the fixture body cover such that as the upper and lower collar are brought into a closely spaced relationship with each other, the member is compressed. This action places a continuous biasing force against the cover urging it toward positive engagement with the upper collar. The fixture body cover, including the fluorescent tube, may then be rotated for alignment purposes and will be retained in the aligned position by means of the frictional force created by the compressible member urging the body cover toward engagement with the upper collar. The arcuate slots define a generally circular configuration and each extends through an arc of approximately 170* whereby the cover body may be moved through an arc of approximately 170* for alignment purposes.

Drop in anchor stud

Abstract: The stud, pin or the like of this invention is used in a blind hole in masonry or similar material. It has a threaded upper end and some distance below the upper end the stud is necked down and garroted with a tapered, frusto conical portion below the neck for expanding a collar which surrounds the neck. The collar is a split ring which has to be compressed to fit into the hole, and upward pull on the stud causes the frusto conical portion to expand the stud and firmly secure it in the wall or other object in which the hole is located. The collar is shaped to prevent it from rotating in the hole.

Terminals for strands and ropes

Abstract: A wire rope or strand is inserted into a bore in a metal terminal blank having an elongate body, a collar at one extremity, and a transitional neck portion merging with the collar. The neck portion has a rounded peripheral depression, which aids plastic flow during reduction. The cross-section of the terminal blank is reduced by swaging or pressing only its body, so that the body grips the rope or strand. The collar has a bearing surface which is directed away from the body and is intended to support a load which puts the rope under tension. When a load is applied to the bearing surface the terminal is under longitudinal compression.

Drill collar incorporating device for jetting drilling fluid transversely into bore hole

Abstract: A self-stabilizing drill collar structure for incorporation into a drill string for deep well rotary drilling includes an elongated cylindrical collar member having an axially extending throughbore for passing drilling fluid downwardly to the lower end of the drill string. An arrangement of easily replaceable and non-fouling nozzles located within slots and protected by the wall of the collar serve to divert clean downwardly flowing drilling fluid from the axial throughbore and discharge it in a jet-like manner laterally outward from the opposite ends of the slots into the annular gap between the collar and bore hole to thereby improve lubrication of the gap and provide better circulation and return of the drilling fluid to the surface for re-cycling, and which enables the drilling to take place at a higher speed and with greater accuracy and stability as regards the desired course of the bore hole. The number of nozzles in operation can be varied as desired by replacing one or more of them with plugs and the collar member can also be provided optionally with reaming flanges to shape the bore hole.

Exterior driving mirror for an automobile vehicle

Abstract: The end of the arm remote from the mirror is mounted in the bore of a socket on a base in such manner as to be released from the base upon application of a blow of predetermined magnitude. The base is adapted to be secured to a vehicle. The end of the arm carries a screw which holds an expanding collar on the arm. The collar has an outer surface which is convergent toward the arm and is inserted in an elastomeric retaining ring interposed between the collar and the bore of the socket. The screw, in axially clamping the collar against the arm, radially compresses the ring between the convergent surface of the collar and the bore and thereby secures the arm to the base while allowing the arm to become automatically released from the base when said blow is applied to the arm.

Removable stem for raise bits

Abstract: A raise bit for enlarging a pilot hole into a larger diameter hole by disintegrating the earth formations surrounding the pilot hole includes a removable drive stem. The removable drive stem allows the raise bit to be transported through small drifts and helps extend the useful lifetime of the raise bit. The raise bit may be assembled without weakening the highly-stressed, heattreated drive stem by welding. The raise bit body includes a multiplicity of rolling cutters for contacting and disintegrating the earth formations surrounding the pilot hole. The raise bit body includes a fixed collar with a truncated conical inside surface. A two-piece, split, removable collar with an inside surface that matches the outside surface of the drive stem and a conical outer surface that matches the inside surface of the fixed collar is positioned around the drive stem. A flange at the end of the drive stem allows the split collar to be drawn up into the fixed collar thereby developing frictional forces between the mating surfaces of the fixed collar, the split collar, and the drive stem. A preload is induced into the system to insure proper torque transmittal at low bit loads.

Riveter having axially latchable clutch

Abstract: In a riveting device, comprising chuck means adapted to receive the mandrel of a blind rivet to exert a cycle of pulling the mandril to set the rivet and break the mandrel and to eject the thus broken mandrel, a means for latching the clutch comprises an axially shiftable member so that the riveting device is latched for a cycle of operation by a simple axial push upon the drive shaft. A bit has a power transmission collar. The drive shaft has a well in which there is a socket. The combination of bit and collar is inserted into the well in the driveshaft whereby the pin and spiral association between collar and socket permit power transmission from the electric drill to the driveshaft. Thus an electric drill having such bit and collar can be used alternately for hole-drilling and power transmission for the riveting device.

The bushing has a thickened portion which engages the collar and a bottle neck shaped outer portion with a radially extending outwardly flanged edge adapted to be bent over the free edge of the collar to tightly grip it, preventing relative rotation. The method includes pushing the bushing into the collar so that its base engages the interior of the base of the collar and the bushing outer portion extends beyond the collar free edge and applying pressure radially outwardly on the inner surface of the bottle neck portion to bend the flanged edge toward the collar free edge.

Clamping arrangement and method

Abstract: A ground clamp arrangement for electrical cables of the type having neutral or ground potential wires concentrically surrounding the insulating jacket of the cable comprises a strip deformable into a collar for disposition radially between the jacket and the ground wires. A clamping ring encircles the ground wires and is tightened against the wires which are thereby pressed against the collar. The collar has interlocking overlapped ends that prevent diametral reduction of the collar so that reduction of the diameter of the cable jacket is prevented. The clamping ring has a terminal for attaching a wire to ground a telephone cable or the like. In the method the deformable member is inserted under several of the neutral wires, then bent around the cable, then pushed under all of the neutral wires to form the collar, after which the clamping ring is applied.

Method of producing trim ring

Abstract: A trim ring comprises an annulus of metal which is affixed to the rim of an automobile wheel to provide a decorative cover for the wheel rim. Disclosed is a trim ring formed into a collar having the general shape of a pie pan from which the base section or hub is removed. The base section is blanked and drawn to form a number of individual retaining clips. Each clip has a wheel rim engaging retention tab extending therefrom such that when the clips are angularly spaced along the outer periphery of the collar and clinched thereto, the tabs describe a series of retaining members spaced along the collar and coaxial thereto. The tabs have protruding teeth for grippingly engaging the rim of the wheel to secure the trim ring to the wheel rim. Disclosed also is the method of originally forming the pie pan shape of the collar, blanking and forming the base section to fabricate retaining clips from the blanked circular sheet and affixing the clips to the collar to produce the wheel gripping members.

The sighting member may be in the form of a loop of wire or a solid disc. The sighting member is positioned over a golf ball during the execution of a golf club swing.

Tool for forming a hole for a fastening element

Abstract: A substantially cylindrical hole is drilled into a support structure, and the end of the hole remote from the point of entry of the drilling tool into the structure is enlarged in its cross-sectional area so as to provide abutment surfaces for spreading portions of a fastening element inserted into the hole subsequently to the drilling thereof. The drilling tool includes a drill shaft, and a drill bit connected to the free end of the drill shaft and having lateral cutting edges. The cutting edges may diverge in direction axially away from the drill shaft and a collar may be provided on the drill shaft which, in cooperation with the inner surface bounding the hole forms a fulcrum for a lever-type angular displacement of the drilling tool for increasing the cross-sectional area of the remote end of the hole. The collar may be mounted on the drill shaft for displacement between a plurality of axially spaced positions and for arresting in any one of these positions so as to adjust the drilling tool to a particular depth of the hole to be drilled.

Expander for random trim tubing

Abstract: A tube expander operable with random length tubing having variable length projection beyond the face of header sheet into which the tube is to be expanded. Rollers in an expander cage are supported on a rotatable mandrel for insertion inward of the tube end. An open ended non-rotatable, tubular thrust collar is adapted to envelop the tube end and is secured about the cage at a predetermined location generally rearward of the rollers. Within the collar and biased toward the open end thereof is a slideable stop sleeve sized to abut the projecting end of the tube. On being advanced over the tube projection toward the header sheet for preliminary positioning, the collar engages the sheet face to register location of the rollers within the tube in alignment with the header sheet. Concomitantly with positioning of the collar, the abutting tube end acts to prevent sleeve movement as to effect relative displacement between sleeve and collar which can then be secured for operation of the expander.
