Abstract: A wire clamping clip for mounting on a stucco wall is constructed as a block member having a workpiece engaging surface and an exposed top surface. A recess is formed in the workpiece engaging surface for receiving a wire. A throughbore is formed in the block adjacent to the recess and a plastic bushing having a cross sectional dimension of the same shape and slightly smaller than the cross sectional dimension of the throughbore is positioned in the throughbore. A hardened pin with a sharpened end is slidingly received in a tight frictional engagement through the center of the plastic bushing and has an enlarged head for abutting against the top end of said bushing and having a length longer than said bushing so that its sharpened end extends beyond the lower end of said bushing.

Abstract: This invention relates to a block member adapted to secure a cable or wire to a support surface. The block member has a pair of cylindroconical bores with each being adapted to receive a pointed pin therethrough. Each pin has a frustoconical end with an included angle which is less than the included angle of the frustoconical portion of the cylindroconical bore. Around the open end of each bore is an impact absorbing ring. The ring is of the same material as the block member and is adapted to substantially absorb the excess energy that the tool used to drive the pins may contain by crushing on impact. The block member has each bore disposed within a freely depending sleeve to permit the axis of the pin and bore to shift, to a point where the axes could move to thereby permit the pointed end of the pin to avoid a substantially impenetrable object.

The switching member includes an electrically non-conducting rotary part having a shaft portion rotatably disposed in the throughbore of the mounting member and a knob portion which includes a flange integrally formed in normal relation to the shaft portion and slidingly engaging the head portion of the mounting member. Stop means is provided for limiting the rotational motion of the switching member between two arcuate positions. An electrical contact member is mounted on the shaft portion and includes an arm portion that is disposed along a chordal flat formed inwardly of the circumferential surface of the shaft portion.

Abstract: A one-piece, snap-in fastener is provided for securing an elongate compressible gasket of given cross-sectional configuration to a panel having an elongate aperture into which the snap-in fastener is secured. The snap-in fastener comprises a bight portion, a pair of resilient leg portions integrally joining the bight portion and normally extending outwardly therefrom in substantially parallel, spaced apart relation. Each leg portion terminates with an inwardly extending foot portion. The bight portion, leg portions and feet portions lie in a common straight plane. A pair of resilient wing portions are integrally formed at the end of the feet portions and diverge from opposite sides of the common straight plane. The leg portions are spaced apart a distance to span the elongate aperture and are shaped to conform to the ends of the aperture in the region adjacent to the bight portion.

Abstract: A one-piece integral resilient grommet of elastomeric material is disclosed for isolating the vibration and noise which is propagated from a fractional horsepower motor. The resilient grommet has a central sleeve portion of resilient deformable material having a cylindrical axial opening. A pair of vibration dampening members are integrally formed on the center sleeve portion and have axially spaced apart end walls that extend radially from the central sleeve portion to define an annular recess for mounting the housing of the fractional horsepower motor. The grommet is attached to a support wall structure by a fastener that extends through the cylindrical axial opening and is brought into threaded engagement with the wall. To dampen the vibration wave propagation in the axial direction and isolate the noise of the motor from the support wall, the pair of vibration dampening members are each formed with a set of radially directed ribs which are angularly offset from each other.

Abstract: A differential-vacuum alarm device is disclosed. The device comprises a housing divided into three chambers by two walls. One wall isolates one chamber from the other two.
