  • Patent number: 9403220
    Abstract: There is disclosed a camber-lock apparatus that provides for both joining and separating a two part hole saw. Said camber-lock apparatus consist of a circuited plate that installs within the boundaries of clasping devises at the top of a cylindrical saw blade. The cylindrical saw blade, with the cutting or teeth edge at the bottom, has a large opening at the top. Within the interior circumference of said opening is attached a series of clasping devices. Said circuited plate, with its attached arbor and pilot bit, comprises the top elements of the saw; which can be rotated into and out of place within the boundaries of said clasping devises. The purpose for removal of said circuited plate is to exposes the interior of the saw and any material jammed therein; thereby allowing for easy removal of said material.

A body of elastomeric material is mold bonded into a first portion of the bushing such that it bridges and at least partially fills the gap. The elastomeric material does not fill or bridge the annular gap in a central area or a second portion of the bushing, such that a void is defined between the inner surface of the outer housing and the outer surface of the inner housing in the central area and second portion. A protrusion extends from the inner surface of the outer housing or the outer surface of the inner member, in the central area such that the void extends between the protrusion and the respective opposed surface. The protrusion functions as a travel limiter for the bushing without compressing the elastomeric material in the first portion.

  • Patent number: 8794608
    Abstract: To provide a vibration isolation apparatus which prevents a vibration isolation leg from being pushed by a resin material injected in a resin molding process and to prevent generation of resin burrs. Because a rubber notch is formed in a first molding product, when the first molding product is placed in a resin mold in an insert molding process, the pressure of the flowing resin material injected in the resin mold through the injection gate can be relieved and thus first wall covering rubber parts may be less pushed by the resin material. This reduces positional deviation of a vibration isolation leg and sealing errors caused by deformation of the first wall covering rubber parts, and thus generation of resin burrs can be suppressed.

    Abstract: A bush for isolating a stabilizer from vibration, is adapted to be fitted from the open end of an axle beam having a substantially U-shaped cross-section, to a stabilizer bar passing through the inside of the axle beam. The bush includes a fitting hole and an opening for guiding the bar into the fitting hole. The opening has a pair of first projections facing each other and a pair of second projections facing each other. When the opening becomes engaged with the bar, the first and second projections sequentially and individually contact with the bar and elastically deform in the direction in which the opening opens.
