Abstract
Abstract A pencil-shaped hand piece is disclosed with one end connected by a flexible wire capable of conveying vibrations to an electric vibrator and with its other end incorporating a threaded aperture into which accessory tips can be mounted. The accessory tips can be in the form of a spatula or a compactor for depositing and/or compacting deposited material in a working area such as a dental mold with vibrations conveyed to the hand piece and the accessory tip first effecting the depositing and then the compacting of the material subsequent to the depositing of the material in the working area. The electric vibrator is adjustable to vary the intensity of the vibrations and is mounted in a casing including supporting means for holding a plurality of accessory tips as well as a supporting member for storing the hand piece when the device is not in operation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
144 words
Hand operated apparatus for enabling the application of damp or dry powdery material into a working area and for subsequently enabling uniform compacting of the powdery material in the working area, said apparatus comprising a main vibration power source comprising an electric vibrator having a physically movable output member providing mechanical vibrations, a rigid pencil-shaped hand piece having first and second ends, accessory tip mounting means connected to said first end of said hand piece for fixedly connecting an accessory tip to said hand piece and a flexible wire-like mechanical vibration conveying means extending between said second end of said hand piece and said physically movable output member for continuously conducting a sufficient quantum of vibrations from said main vibration power source to said hand piece and an accessory tip mounted thereon to enable the compacting of said powdery material by said accessory tip.
Claim 2
Dependent Claim
144 words
Hand operated apparatus for enabling the application of damp or dry powdery material into a working area and for subsequently enabling uniform compacting of the powdery material in the working area, said apparatus comprising a main vibration power source comprising an electric vibrator having a physically movable output member providing mechanical vibrations, a rigid pencil-shaped hand piece having first and second ends, accessory tip mounting means connected to said first end of said hand piece for fixedly connecting an accessory tip to said hand piece and a flexible wire-like mechanical vibration conveying means extending between said second end of said hand piece and said physically movable output member for continuously conducting a sufficient quantum of vibrations from said main vibration power source to said hand piece and an accessory tip mounted thereon to enable the compacting of said powdery material by said accessory tip.
