Abstract
Abstract A reaction-type vibration generator which includes, generally, a housing having therein two fixed shafts which are geared together so that they rotate synchronously in opposite directions. Each of these two fixed shafts having an eccentric mass affixed to it, which mass comprises a portion one-half of the total mass rotated by that shaft. These shafts each further have a sleeve disposed concentrically about it, and these sleeves each support the other portion (one-half) of the total mass rotated by the individual shafts. The sleeves further are keyed to the shafts by means of a pair of toothed gears affixed to the shafts and to the sleeves, respectively, in a fashion such that the assembly can be easily loosened, the sleeves angularly rotatably displaced with respect to the shafts to vary the net unbalanced mass to, in turn, vary the amplitude of vibration of the vibration generator, and then fixedly keyed together again so that the masses affixed to the fixed shafts and to the sleeves rotate in synchronism. Scale means are associated with each shaft and sleeve combination, to accurately establish the desired amplitude of vibration.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
129 words
A reaction-type vibration generator comprising a housing; at least one shaft having a mass eccentrically secured thereto rotatably supported within said housing; a sleeve concentrically disposed about said shaft and having a like mass eccentrically secured thereto in a like fashion; a locking mechanism comprising first lock means fixedly secured to said sleeve and second lock means fixedly secured to said shaft, said first and second lock means being releasably locked together to cause said shaft and said sleeve to rotate together as a unit, and being adapted to be unlocked to permit said shaft and said sleeve to be rotated with respect to one another to angularly adjustably position said masses affixed thereto with respect to one another to vary the amplitude of vibration of said vibration generator.
Claim 2
Dependent Claim
129 words
A reaction-type vibration generator comprising a housing; at least one shaft having a mass eccentrically secured thereto rotatably supported within said housing; a sleeve concentrically disposed about said shaft and having a like mass eccentrically secured thereto in a like fashion; a locking mechanism comprising first lock means fixedly secured to said sleeve and second lock means fixedly secured to said shaft, said first and second lock means being releasably locked together to cause said shaft and said sleeve to rotate together as a unit, and being adapted to be unlocked to permit said shaft and said sleeve to be rotated with respect to one another to angularly adjustably position said masses affixed thereto with respect to one another to vary the amplitude of vibration of said vibration generator.
Claim 3
Dependent Claim
66 words
The reaction-type vibrator generator of claim 1, wherein said first lock means comprises an adjusting dial and said second lock means comprises a clutch, the mating faces of said adjusting dial and said clutch having a plurality of teeth thereon which meshingly engage to releasably lock said adjusting dial and said clutch together to cause said shaft and said sleeve to rotate together as a unit.
Claim 4
Dependent Claim
54 words
The reaction-type generator of claim 2, further including a locknut threadedly affixed to said shaft so as to engage and forcibly urge said clutch in engagement with the adjusting dial affixed to the sleeve concentrically disposed about it, to meshingly engage the teeth thereon to releasably lock said adjusting dial and said clutch together.
Claim 5
Dependent Claim
46 words
The reaction-type vibrator of claim 3, wherein biasing means are affixed to one of said adjusting dial and said clutch for biasing said clutch out of engagement with said adjusting dial, whereby said clutch and said adjusting dial are automatically disengaged when said locknut is loosened.
Claim 6
Dependent Claim
68 words
The reaction-type vibration generator of claim 3, wherein said adjusting dial has a displacement scale affixed to it and said clutch has an index marker affixed to it, said displacement scale and said index marker being affixed thereto and calibrated in a fashion such that the amplitude of vibration of said vibration generator can be adjusted by aligning said index marker with corresponding indicia on said displacement scale.
Claim 7
Dependent Claim
162 words
A reaction-type vibration generator comprising a housing; a pair of shafts each having a mass eccentrically secured thereto rotatably supported within said housing and adapted to be rotated in opposite directions in synchronism; a sleeve concentrically disposed about each of said shafts and having a like mass eccentrically secured thereto in a like fashion; a locking mechanism associated with each of said shafts, said locking mechanisms each comprising first lock means fixedly secured respectively to one of said sleeves and second lock means fixedly secured to the associated one of said shafts, said first and second lock means being releasably locked together to cause said shaft and said sleeve associated with it to rotate together as a unit, and being adapted to be unlocked to permit said shaft and said sleeve to be rotated with respect to one another to angularly adjustably position said masses affixed thereto with respect to one another to vary the amplitude of vibration of said vibration generator.
Claim 8
Dependent Claim
162 words
A reaction-type vibration generator comprising a housing; a pair of shafts each having a mass eccentrically secured thereto rotatably supported within said housing and adapted to be rotated in opposite directions in synchronism; a sleeve concentrically disposed about each of said shafts and having a like mass eccentrically secured thereto in a like fashion; a locking mechanism associated with each of said shafts, said locking mechanisms each comprising first lock means fixedly secured respectively to one of said sleeves and second lock means fixedly secured to the associated one of said shafts, said first and second lock means being releasably locked together to cause said shaft and said sleeve associated with it to rotate together as a unit, and being adapted to be unlocked to permit said shaft and said sleeve to be rotated with respect to one another to angularly adjustably position said masses affixed thereto with respect to one another to vary the amplitude of vibration of said vibration generator.
Claim 9
Dependent Claim
76 words
The reaction-type vibration generator of claim 6, wherein each of said first lock means comprises an adjusting dial and each of said second lock means comprises a clutch, the mating faces of said adjusting dials and said clutches having a plurality of teeth thereon which meshingly engage to releasably lock said adjusting dials and said clutches together to cause said shafts and said sleeves with which they are respectively associated to rotate together as a unit.
Claim 10
Dependent Claim
60 words
The reaction-type generator of claim 7, further including a locknut threadedly affixed to each of said shafts so as to engage and forcibly urge the clutch associated with that shaft in engagement with the adjusting dial affixed to the sleeve concentrically disposed about it, to meshingly engage the teeth thereon to releasably lock said adjusting dial and said clutch together.
Claim 11
Dependent Claim
46 words
The reaction-type vibrator of claim 8, wherein biasing means are affixed to each associated pair of adjusting dials and clutches for biasing said clutch out of engagement with said adjusting dial, whereby said clutches and said adjusting dials are automatically disengaged when said locknuts are loosened.
Claim 12
Dependent Claim
