Counterweight bag tensioning device

Claim 2

In a bag supporting and tensioning assembly for supporting and providing tension for dust collecting filter bags in a bag house throughout a predetermined range of bag weight, the improvement comprising; rigid means adapted to be secured within a bag house, an elongated lever arm member having means defining a first horizontal axis of rotation intermediate the axial ends thereof and being pivotally supported at said first axis of rotation by said rigid means; said arm member pivotally supporting at least one such dust collecting filter bag at pivot means defining a second horizontal axis of rotation inwardly adjacent one end of said arm member, weight means secured to said arm member at a point adjacent the other end of said arm member and longitudinally spaced from said means defining said first axis of rotation in counterbalancing relationship with said bag, said point of securement and said means defining said first axis of rotation being located on a substantially horizontal line, and said pivot means defining said second axis being located substantially below an extension of said horizontal line from said point of securement through and beyond said first axis.

Claim 3

A bag supporting and tensioning assembly as specified in claim 1 wherein said rotation limiting means comprises a bottom flange portion of said rigid means.

Claim 4

A bag supporting and tensioning assembly as specified in claim 1 wherein said first horizontal axis of rotation is integral with said arm member.

Claim 5

A bag supporting and tensioning assembly as specified in claim 1 wherein said first horizontal axis of rotation is vertically intermediate the longitudinally extending sides of said arm member.

Claim 6

A bag supporting and tensioning assembly as specified in claim 1 wherein means pivotally supporting at least one of said dust collecting bags comprises a strap member pivotally connected at one end thereof to said arm member and connected at the other end thereof to said dust collecting bags.

Claim 7

A bag supporting and tensioning assembly as specified in claim 5 wherein said means pivotally supports a plurality of dust collecting bags.

Claim 8

A bag supporting and tensioning assembly as specified in claim 1 additionally including rotation limiting means which limit the rotation of said arm member about said first horizontal axis of rotation.

Claim 9

A bag supporting and tensioning assembly as specified in claim 7 additionally including rotation instigating means which result in said arm member contacting said rotation limiting means with force sufficient to dislodge at least a portion of accumulated particulate matter from said dust collecting bags.

Claim 10

A bag supporting and tensioning assembly as specified in claim 8 wherein sAid rotation instigating means comprises at least one high pressure air discharge apparatus adapted to be secured to the bag house upwardly of said dust collecting bags.

Claim 11

In a bag supporting and tensioning assembly for supporting and providing tension for dust collecting filter bags in a bag house throughout a predetermined range of bag weight, the improvement comprising; a bag house, rigid means secured within said bag house, an elongated lever arm member having means defining a first horizontal axis of rotation intermediate the axial ends thereof and being pivotally supported at said first axis of rotation by said rigid means, said arm member pivotally supporting at least one of such dust collecting bags at pivot means defining a second horizontal axis of rotation inwardly adjacent one end of said arm member, weight means secured to said arm member at a point adjacent the other end of said arm member and longitudinally spaced from said means defining said first axis of rotation in counterbalancing relationship with said bag, said point of securement and said means defining said first axis of rotation being located on a substantially horizontal line and said pivot means defining said second axis being located substantially below an extension of said horizontal line from said point through and beyond said first axis, rotation limiting means on said rigid means which limit the rotation of said arm member about said first horizontal axis of rotation, and rotation instigating means which result in said arm member contacting said rotation limiting means with force sufficient to dislodge at least a portion of accumulated particulate matter from said dust collecting bags.

Claim 12

In a bag supporting and tensioning assembly for supporting and providing tension for dust collecting filter bags in a bag house throughout a predetermined range of bag weight, the improvement comprising; a bag house, rigid means secured within said bag house, an elongated lever arm member having means defining a first horizontal axis of rotation intermediate the axial ends thereof and being pivotally supported at said first axis of rotation by said rigid means, said arm member pivotally supporting at least one of such dust collecting bags at pivot means defining a second horizontal axis of rotation inwardly adjacent one end of said arm member, weight means secured to said arm member at a point adjacent the other end of said arm member and longitudinally spaced from said means defining said first axis of rotation in counterbalancing relationship with said bag, said point of securement and said means defining said first axis of rotation being located on a substantially horizontal line and said pivot means defining said second axis being located substantially below an extension of said horizontal line from said point through and beyond said first axis, rotation limiting means on said rigid means which limit the rotation of said arm member about said first horizontal axis of rotation, and rotation instigating means which result in said arm member contacting said rotation limiting means with force sufficient to dislodge at least a portion of accumulated particulate matter from said dust collecting bags.

Claim 13

A bag supporting and tensioning assembly as specified in claim 10 wherein said rotational instigating means comprises at least one high pressure air discharge apparatus secured to said bag house upwardly of said dust collecting bags.
