Patent ID: 8776626

Claim:
A pneumatically driven oscillatory motor comprising: a. a housing, the housing further comprising an air column defined by: i. an air inlet ii. an air outlet iii. a gear chamber disposed between the air inlet and air outlet in the air column; b. a fan gear located in the gear chamber and serving as a portion of the air column; c. an axle, coaxially mounted on the fan gear and extending through an opening of the housing; d. a hub with an eccentric shaft, mounted upon an end of the axle opposite the fan gear; e. a bearing situated about the hub; and f. a collar positioned over the bearing, said collar having a collar arm extending radially therefrom; wherein, upon rotation of the fan gear, rotation is imparted to the axle and the associated hub , which then rotates eccentrically, causing a wobbling effect on the bearing and associated collar which then imparts an oscillating vertical motion upon the collar arm.
