Tensioning device

Claim 2

An elongated retaining device comprising: a body member having one end portion thereof adapted to support a supported member therefrom and having an outwardly biased bifurcated portion adjacent the other end portion thereof; and each of the legs of said bifurcated portion including retaining means extending longitudinally therealong which are adapted to be cooperable with a seating portion of a supporting member to selectively retain said body member at any of a plurality of locations therealong with respect to such a seating portion by overcoming the bias of said bifurcated portion and seating a selected section of said retaining means on such a seating portion.

Claim 3

A retaining device as specified in claim 1 wherein said retaining means are a plurality of ratchet teeth extending longitudinally along the exterior sides of said legs.

Claim 4

A retaining device as specified in Claim 1 wherein said body member comprises a pair of independent elongated sections which are pivotally joined together intermediate the axial ends thereof in scissor like fashion.

Claim 5

A retaining device as specified in claim 3 wherein said legs are the portion of said independent elongated sections on one side of the pivot axis.

Claim 6

A retaining device as specified in claim 4 additionally including means applying an inward biasing force to the portion of said independent elongated sections on the other side of the pivot axis.

Claim 7

A retaining device as specified in claim 5 additionally including an additional elongated member adapted to carry such a supported member adjacent one end portion thereof and being supported by said first mentioned member adjacent the other end thereof.

Claim 8

A retaining device as specified in claim 6 additionally including a biasing means disposed intermediate said first mentioned member and said another member and being cooperable therewith to bias said members away from each other.

Claim 9

A retaining device as specified in claim 2 wherein the seating portion comprises a bore extending through such a supporting member and said ratchet teeth are selectively seated on such a supporting member outwardly adjacent a peripheral portion of said bore.

Claim 10

In a dust collecting baghouse assembly wherein a filter bag assembly is supported between spaced support structures and an elongated tensioning device adjustably communicates between one end of said filter bag assembly and the one of said support structures adjacent thereto, the improvement comprising: said tensioning device comprising a body member having one end portion thereof adapted to support said one end of said filter bag assembly therefrom and having an outwardly biased bifurcated portion adjacent the other end portion thereof; and each of the legs of said bifurcated portion including retaining means extending longitudinally therealong which are adapted to be cooperable with a seating portion of said one of said support structures to selectively retain said body member at any of a plurality of locations therealong with respect to said seating portion by overcoming the bias of said bifurcated portion and seating a selected section of said retaining means on such a seating portion.

Claim 11

In a dust collecting baghouse assembly wherein a filter bag assembly is supported between spaced support structures and an elongated tensioning device adjustably communicates between one end of said filter bag assembly and the one of said support structures adjacent thereto, the improvement comprising: said tensioning device comprising a body member having one end portion thereof adapted to support said one end of said filter bag assembly therefrom and having an outwardly biased bifurcated portion adjacent the other end portion thereof; and each of the legs of said bifurcated portion including retaining means extending longitudinally therealong which are adapted to be cooperable with a seating portion of said one of said support structures to selectively retain said body member at any of a plurality of locations therealong with respect to said seating portion by overcoming the bias of said bifurcated portion and seating a selected section of said retaining means on such a seating portion.
