A vehicle body mount assembly comprising an upper sheet metal spacer member, a lower sheet metal spacer member, and a sheet metal clip member. The upper sheet metal spacer member includes a flange portion having a central aperture and a tubular portion extending downwardly from the flange portion in coaxial relation to the central aperture and including a radially inwardly extending lip adjacent the lower end thereof. The lower spacer member includes a flange portion having a central aperture and a tubular portion extending upwardly from the flange portion in coaxial relation to the central aperture thereof and sized to be received telescopically within the upper spacer member tubular portion. The clip member is split and is sized to fit snappingly over and encircle a reduced diameter annular seat defined on the upper end of the lower spacer member tubular portion and includes prongs struck radially outwardly therefrom for snapping coaction with the lip on the upper spacer member tubular portion in response to relative axial telescoping movement of the upper end of the lower spacer member tubular portion into the lower end of the upper spacer member tubular portion.

A latch member of a case or similar container blow-molded from thermoplastic material is pivotally and permanently secured to the case by a bearing formed substantially simultaneously with and from the same thermoplastic material as the body of the case. Formation of a permanent bond between the bearing member and the latch member is avoided by employing a latch member formed of material having a higher melt temperature than the material used in the formation of the main body of the case and the bearing member, and also by effecting relative movement between the latch member and the bearing member while the thermoplastic material forming the bearing member is still in a heated condition. Apparatuses for positioning the latch member within the mold are also disclosed.

A reel driving device which comprises a drive disk having a drive shaft fixing boss for prohibiting the drive shaft from idling, and impact mitigating bosses for mitigating an impact force exerted by the motor, provided therein opposed to each other with respect to the drive shaft fixing boss; a reel having holes for receiving the drive shaft fixing boss and the impact mitigating bosses provided at corresponding positions thereof; and reel fixing means for prohibiting the reel from moving along the drive shaft.

A pivoting adjustment screw for mounting the bolt of a latch to provide vibrational damping along with increasing preload as the contact point of the adjustment screw to the mating structure shifts in a shock or vibrational environment. The adjustment screw includes a pivoting portion which permits the screw to pivot which allows a rotating rather than a scraping or abrading movement in response to the relative movement between the elements being connected.

A dynamic linear vibration damper consisting of a support member and an inertia member assembled by an elastomer for vibration damping purposes. An extension defined on the support member is received within an opening in the inertia member, and an elastomer interposed between the extension and the opening surfaces is installed under tension whereby the resiliency of the elastomer places the elastomer under compression as confined by the opening to frictionally maintain the assembly of the components.

A collecting rope which is intended especially for collecting oil from the surface of water, the rope comprising a drive chain which is situated inside a cylindrical part, which is surrounded by a lightweight float layer, which is surrounded by another cylindrical part, oil-collecting bristles being attached to the outer surface of the outer cylinder. The cylindrical parts can rotate in relation to the drive chain, since the joint between them consists of resilient protrusions on the inner surface of the inner cylinder. The cylinders and the chain are, however, locked to each other in the longitudinal direction.

A joint prosthesis comprises two relatively inextensible primary components that are spaced apart from one another. Disposed between and spaced from both of the components is a pivot member. The pivot member is resiliently secured to each of the primary components so as to permit relative rotation between the primary components and the pivot member. As a result, the two primary components of the prosthesis can rotate toward and away from each other about an axis that is disposed at least adjacent to and at least approximately parallel to a central longitudinal axis of the pivot member. The pivot member and the primary components of the prosthesis are preferably secured together by one or more bodies of elastomer.

A damping spacer for parallel overhead conductors in which at least two rigid spacing members are provided with integral hub structures having circular, integral raised wall portions and recesses. The thickness of the wall portions is considerably smaller than the width of the recesses, and the wall portions are opposed and radially offset, such that when the recesses and raised wall portions of the hub structures are placed together in mating relationship, and with the arms thereof located in a position to be clamped to two overhead conductors, the recesses in the hub structures permit the wall portions of the hub structures to move in the recesses, the wall portions of the respective hub structures serving to limit relative movement of the spacing members.

Shock mount for protective structure for tractors, including an upstanding post affixed to the tractor to protect the operator in the event that the tractor rolls over or in the event something falls on the tractor. A post mounting member is affixed with the tractor chassis, and an assembly of an elastomer insert and a bushing and a bolt interconnect the post and the chassis, and actually the elastomer insert and the bushing are presented in duplicate in the assembly. The inserts have a tapered interior opening, and the bushing is received within the opening to urge the insert outwardly into snug fit with the mounting member.

A resilient bushing assembly comprises inner and outer tubular members spaced by an elastic bushing under sufficient pressure to extrude a yieldable detent portion thereof through a radial opening in the inner member and into a detent receiving groove of a bolt located at a detent position within the inner member. The ends of the bolt extend axially beyond the bushing assembly to ride within a pair of guide slots in a corresponding pair of brackets and to seat in supported and predetermined located relationship at the slot bases. A bolt head and nut oversize with respect to the slots and spaced axially outwardly of the brackets at opposite ends of the bolt enable assembly of the bushing assembly and bolt at the detent position by movement of the bolt to its seated position through open ends of the slots whereupon the nut is tightened to draw the bolt from the detent position to clamp the bushing assembly between the brackets. Axial movement limiting flanges of the brackets overlie the bolt head and nut at the tightened position, but freely clear the flanges axially outwardly thereof during assembly when the bolt is at the detent position.
