Abstract
Abstract A wall-mounted agitator for particulate material having an agitator panel within a gravity conveying wall for the material and a frame with a vibrator external to the wall and attached to the panel by means of resilient mounts. The mounts each include annular flange means for attachment to an aperture in the wall and an elastic annulus of sleeve-like form. The annulus extends from the flange means to the panel and frame, respectively, in opposite directions.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
A particulate material agitator comprising, in combination, an agitator panel formed to extend in generally parallel spaced relationship to and within a wall of a conveyor for said material, an agitator frame external to said wall and having a powered vibrator thereon, an elongate spacer extending through an aperture in said wall and rigidly securing the panel and frame together in spaced relationship, the agitator being adapted for vibrating the panel and frame predominantly in a direction parallel to said wall, and a mount including annular flange means adapted for attachment to said wall about said aperture and an elastic annulus of sleeve-like form extending from the flange means in opposite directions along the extent of the spacer to ends of said annulus respectively terminating at opposing surfaces of the frame and panel, said annulus being compliant to movement of the frame and panel in directions both parallel and normal to said wall.
Claim 2
Dependent Claim
153 words
A particulate material agitator comprising, in combination, an agitator panel formed to extend in generally parallel spaced relationship to and within a wall of a conveyor for said material, an agitator frame external to said wall and having a powered vibrator thereon, an elongate spacer extending through an aperture in said wall and rigidly securing the panel and frame together in spaced relationship, the agitator being adapted for vibrating the panel and frame predominantly in a direction parallel to said wall, and a mount including annular flange means adapted for attachment to said wall about said aperture and an elastic annulus of sleeve-like form extending from the flange means in opposite directions along the extent of the spacer to ends of said annulus respectively terminating at opposing surfaces of the frame and panel, said annulus being compliant to movement of the frame and panel in directions both parallel and normal to said wall.
Claim 3
Dependent Claim
27 words
The combination of claim 1, in which the spacer is dimensional to compress the annulus to a dimension less than its unstressed length between said opposing surfaces.
Claim 4
Dependent Claim
46 words
The combination of claim 2, in which the unstressed length of the annulus is sufficiently greater than the distance between said opposing surfaces to cause all portions of the annulus to remain under compression throughout a predetermined vibratory movement of the spacer in said normal direction.
Claim 5
Dependent Claim
50 words
The combination of claim 1, in which the spacer comprises a bolt extending through the panel and frame, a tubular sleeve surrounding the bolt and extending between the panel and frame, and means for applying tension to the bolt to draw the sleeve into abutment with the panel and frame.
Claim 6
Dependent Claim
23 words
The combination of claim 1, in which a portion of the annulus is bonded to the flange means and extends to the panel.
Claim 7
Dependent Claim
25 words
The combination of claim 1, in which at least end of the annulus is provided with a washer bonded thereto and received over the spacer.
Claim 8
Dependent Claim
37 words
The combination of claim 1, in which the support means comprise a pair of coaxial abutting annular members each comprising elastic material of sleeve-like form, said pair of members extending in opposite directions from said flange means.
Claim 9
Dependent Claim
18 words
The combination of claim 7, in which the elastic material of the sleeve-like members is of conical form.
Claim 10
Dependent Claim
24 words
The combination of claim 7, in which one of said pair of members is bonded to the flange means and extends to the panel.
Claim 11
Dependent Claim
38 words
The combination of claim 7, in which one end of each of said pair of members is bonded to the flange means and the other end is provided with a washer bonded thereto and received over the spacer.
Claim 12
Dependent Claim
16 words
The combination of claim 7, in which said pair of members are substantially identical in structure.
Claim 13
Dependent Claim
30 words
The combination of claim 1, with means to apply a resilient force between said wall and frame in a direction having a component opposed to the weight of the agitator.
