A shaft is journaled to rotate in a housing and is formed with an enlarged disc which carries an elastomeric ring. As the shaft rotates, the ring is compressed against and is massaged by protrusions extending axially into the housing and coacting with the ring to apply a retarding torque to the shaft. In one embodiment, the protrusions are semispherical buttons which are formed integrally with the end wall of the housing. In another embodiment, the protrusions are spherical balls which are free to spin in semispherical pockets formed in the end wall of the housing.

Device for dampening rotary motion

A rotatable shaft carries a hard plastic disc located in a housing. A braking member in the form of a steel washer is sandwiched between the plastic disc and a washer-like elastomeric spring which is compressed against an axially facing wall of the housing. The spring urges the braking member frictionally against the disc to retard rotation thereof and dampen rotation of the shaft. By adjusting a screw, the disc may be shifted axially toward or away from the spring to change the compression thereof and thereby change the retarding torque applied to the disc.

The anchor includes a stud holder having one end which threadably receives a threaded stud. A flat tongue-like driving head projects axially from the other end of the stud holder and is formed with an eye for receiving one end portion of a wire tie for establishing a positive lateral load connection between an outer masonry veneer wall and an inner supportive wall having a layer of insulation thereon. An integral, radially extending flange is formed at the inner end of the driving head and stabilizes the stud holder while the latter is being driven by a power-rotated socket. When the stud is fully driven, the flange seals a hole drilled in the insulation by the stud holder. The inner end of the stud holder includes cutting elements which enable the stud holder to drill effectively through both hard and soft insulation. The eye through the driving head is shaped so as to eliminate the need of establishing precise angular alinement between the driving head and the wire tie.

The terminal assembly includes a terminal element made of yieldable material and a tubular post made of soft, flowable material. One end portion of the terminal element is defined by a slotted tube-like member adapted to telescope into the post. When the post and the tube-like member are squeezed axially together during assembly, the tube-like member collapses axially and expands radially to cause the soft material of the post to flow into and interlock with the slots and thereby establish a positive electrical and mechanical connection between the terminal element and the post.

Electrical terminal assembly and method of making the same

An assembly for fastening a flexible membrane to a layer of insulation on a roof deck includes a plastic disc and a threaded screw which, when tightened, clamps the disc to the membrane. Angularly spaced pins are formed integrally with and depend from the underside of the disc and bite into the membrane to help prevent edgewise tearing of the membrane when wind uplift forces are exerted on the membrane. The pins preferably are formed between the ends of radially extending and angularly spaced ribs which depend from the underside of the disc to resist upward flexing of the disc.
