Abstract
Abstract A vibratory motor with a vertical shaft is eccentrically loaded by two pairs of outrigger arms mounted by a splined connection on the top and bottom extremities of the shaft, the splines of each shaft extremity being interrupted by an axial gap enabling the raising of the hub of the lower arm of the respective pair into a disengaged position in which the arm may be rotated with reference to its mate to vary the effective eccentricity. The lower arm of the bottom pair is linked with a vertical rod, passing axially through the hollow motor shaft, which carries at its projecting top a handwheel enabling that rod to be raised and rotated whereby that lower arm can be disengaged from the shaft and swung into a different angular position relative to the upper arm of that pair.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
A vibratory motor comprising: a motor body provided with a throughgoing shaft having projecting extremities; a first pair of eccentric loads on one of said extremities; a second pair of eccentric loads on the other of said extremities, at least one load of at least said first pair being provided with a fluted hub matingly engaging a ribbed shaft portion with freedom of axial disengagement therefrom to enable readjustment of the angular spacing of the loads of said first pair; and link means engaging said one load while passing in axial direction through said body for manipulation at a location remote from said first pair, said one load being axially movable by said link means for disengagement of its hub from said shaft and being thereupon rotatable by said link means into a different angular position relative to said shaft.
Claim 2
Dependent Claim
140 words
A vibratory motor comprising: a motor body provided with a throughgoing shaft having projecting extremities; a first pair of eccentric loads on one of said extremities; a second pair of eccentric loads on the other of said extremities, at least one load of at least said first pair being provided with a fluted hub matingly engaging a ribbed shaft portion with freedom of axial disengagement therefrom to enable readjustment of the angular spacing of the loads of said first pair; and link means engaging said one load while passing in axial direction through said body for manipulation at a location remote from said first pair, said one load being axially movable by said link means for disengagement of its hub from said shaft and being thereupon rotatable by said link means into a different angular position relative to said shaft.
Claim 3
Dependent Claim
22 words
A motor as defined in claim 1 wherein said shaft is hollow, said link means being a rod axially traversing said shaft.
Claim 4
Dependent Claim
39 words
A motor as defined in claim 2 wherein said shaft is substantially vertical, said first pair being mounted on a bottom extremity of said shaft, said link means terminating in a handgrip overlying the top extremity of said shaft.
Claim 5
Dependent Claim
61 words
A motor as defined in claim 1 wherein said ribbed shaft portion is divided into two ribbed parts respectively engaging the loads of said first pair, said parts being axially separated by a ribless gap of a width at least equaling that of said fluted hub, the latter being alignable by said link means with said gap preparatorily to said readjustment.
Claim 6
Dependent Claim
28 words
A motor as defined in claim 4 wherein the other load of said first pair is provided with clamping means fixedly securing same to its respective ribbed part.
Claim 7
Dependent Claim
63 words
A motor as defined in claim 1 wherein each of said extremities includes a ribbed shaft portion axially adjoining a ribless zone wide enough to accommodate a fluted hub on one load of the respective pair normally engaging said ribbed shaft portion, thereby enabling said one load of each pair to be angularly adjusted with reference to the other load of the pair.
Claim 8
Dependent Claim
89 words
A motor as defined in claim 6 wherein the other load of said first pair if fixedly positioned on said shaft, the ribbed shaft portion of said other of said extremities being divided into two axially separated ribbed parts normally engaged by respective fluted hubs of said second pair, the loads of said second pair being jointly axially shiftable into respective alignment with a ribless part between said ribbed parts and a ribless part beyond one of said ribbed parts for independent rotary adjustment with reference to said shaft.
Claim 9
Dependent Claim
31 words
A motor as defined in claim 7 wherein said shaft is substantially vertical, said first and second pairs being respectively mounted on a bottom and a top extremity of said shaft.
Claim 10
Dependent Claim
28 words
A motor as defined in claim 1 wherein each of said loads comprises a substantially straight outrigger arm provided near one end with a bore receiving said shaft.
