Patent number: 4435005Abstract: A coupling sleeve for joining the ends of two conduits. One end is threaded, the other is unthreaded. The conduit has a female thread which engages the threaded end. The unthreaded end has a terminal portion of reduced external diameter running to an inwardly displaced groove in which a locking ring is disposed. The end of the coupling sleeve which engages the unthreaded conduit end has a recess in which the locking ring is axially slidable and a flange that engages a full diameter external section of the unthreaded end. The recess is long enough to permit the coupling sleeve to be fully received on the unthreaded conduit end when the female thread is disengaged from the threaded end of the conduit.Type: GrantFiled: May 28, 1980Date of Patent: March 6, 1984Assignee: Berger Industries, Inc.Inventors: Sidney Berger, Salvatore Buda, Burton Weintraub

Patent number: 4146252Abstract: A coupling sleeve surrounds two adjacent pipe ends to be coupled together. A continuously-converging, spiral-shaped channel is provided at opposite end regions of the sleeve. A continuously-converging spiral-shaped split constrictable member is located in and angularly movable through each channel. Actuating members in force-transmitting relationship with each trailing end region of a respective constrictable member are operative for angularly moving the latter through each channel, and for radially constricting each constrictable member about and in sealing engagement with the entire periphery of each respective pipe end. In the fully clamped position, each leading end region is overlapped by each respective trailing end region. The spiral-shaped channel is formed in one embodiment by spiral-shaped walls of the sleeve itself, or in another embodiment by a spiral-shaped insert which is received in a circular groove formed by circular-shaped walls of the sleeve.Type: GrantFiled: January 16, 1978Date of Patent: March 27, 1979Assignee: Berger Industries, Inc.Inventor: Salvatore Buda

Patent number: 4096556Abstract: A lamp harp includes a stiff bracket and a resilient bail. The bracket has a base and diametrically opposed bracket arms extending upwardly from the base. Each arm has a hollow interior and includes a channel portion which is formed by a pair of opposed parallel side walls and a base wall. At the point of transition from the channel portion to a U-shaped portion which joins the channel to the base is retaining means in the form of tabs which may be integrally formed with the side walls of the U-shaped portions to enclose the hollow interiors of the arms. Lateral slots are provided in the side walls of the channels immediately above the tabs to form abutment surfaces. The bail includes two downwardly extending free end portions which terminate in end faces and which have spaced above the end faces flats having a substantially rectangular transverse cross-sectional configuration.Type: GrantFiled: November 4, 1976Date of Patent: June 20, 1978Assignee: Berger Industries, Inc.Inventors: Sidney Berger, Salvatore Buda

Patent number: 4082319Abstract: A coupling sleeve for joining the ends of two conduits. One end is threaded, the other is unthreaded. The coupling sleeve has a female thread which engages the threaded end. The unthreaded end has a terminal portion of reduced external diameter running to an inwardly displaced groove in which a locking ring is disposed. The end of the coupling sleeve which engages the unthreaded conduit end has a recess in which the locking ring is axially slidable and a flange that engages a full diameter external section of the unthreaded end. The recess is long enough to permit the coupling sleeve to be fully received on the unthreaded conduit end when the female thread is disengaged from the threaded end of the conduit.Type: GrantFiled: July 6, 1976Date of Patent: April 4, 1978Assignee: Berger Industries, Inc.Inventors: Sidney Berger, Salvatore Buda, Burton Weintraub

Patent number: 4050722Abstract: Each section of a conduit with a constant diameter axial passageway has male pipe threads formed on its outer wall surface at one end. A coupling sleeve is retained captively on the other end of the conduit section by a resilient lock ring means positioned partially in an annular lock ring groove disposed on the outer surface of the conduit section axially inwardly of the end face of the conduit section, i.e. -- in a direction along the conduit section away from this end face, and partially in an annular lock ring groove disposed on the inner surface of the coupling sleeve. The lock ring means spans the two annular lock ring grooves to prevent the coupling sleeve from being pulled axially outwardly off the conduit section.Type: GrantFiled: October 14, 1975Date of Patent: September 27, 1977Assignee: Berger Industries, Inc.Inventors: Sidney Berger, Salvatore Buda, Burton Weintraub

Patent number: 4047743Abstract: A light walled circular metallic conduit including a first conduit member and a second conduit member. An expanded section is at one end of the first conduit member and an end of said second conduit member is snugly telescoped within said expanded section of said first conduit member. The expanded section has external threads thereon and a nut is provided which is internally threaded. Inside the nut is a split ring. The nut encircles a seal. Upon tightening the nut the split ring bites into the second conduit member. A skirt is affixed to the nut and includes a finger which extends into a gap between the nut and the second conduit member so as to prevent water from leaking into said gap and into the interior of said first and second conduit members.Type: GrantFiled: April 3, 1975Date of Patent: September 13, 1977Assignee: Berger Industries, Inc.Inventors: Burton L. Weintraub, Salvatore Buda

Patent number: 4005879Abstract: Each section of a conduit has a male pipe thread formed on its outer wall surface at one end. The other end of each conduit section has a short length of decreased outside diameter extending axially inwardly with a decreased axial passageway through the reduced diameter length. A sloping annulus is formed between the length of decreased outside diameter and the remainder at the conduit section. The other end is flared and has a flat end face substantially perpendicular to the longitudinal axis of the conduit section. A coupling sleeve has an annular flange at its axially inward end which defines a central opening such that the coupling sleeve may slide freely to a limited extent over the length of decreased diameter of the other end of the conduit section. The axially outward end of the coupling sleeve has female machine threads formed thereon. Intermediate the inner surface of the flange and the threaded portion is a sloped shoulder.Type: GrantFiled: October 14, 1975Date of Patent: February 1, 1977Assignee: Berger Industries, Inc.Inventors: Sidney Berger, Salvatore Buda, Burton Weintraub

Patent number: 3984130Abstract: Each section of an intermediate metal conduit with a constant diameter axial passageway has male pipe threads formed on its outer wall surface at one end. The other end of each conduit section has a short length of decreased outside diameter extending axially inwardly from the flat end face of the section, to form an external annular stop shoulder. A coupling sleeve has a pair of annular flanges which define central openings in mutual axial alignment but of different diameters such that the coupling sleeve may slide freely to a limited extent over the full external diameter of said other end of the conduit section. The coupling sleeve is retained captively on this other end by a resilent constrictable lock ring positioned in an annular lock ring groove disposed axially inwardly of the stop shoulder. When the coupling ring is unstressed, it protrudes, in part, radially outwardly of the groove and is in the path of movement of one of the flanges. The coupling sleeve can be retracted, i.e.Type: GrantFiled: March 17, 1975Date of Patent: October 5, 1976Assignee: Berger Industries, Inc.Inventors: Sidney Berger, Salvatore Buda, Burton Weintraub
