Abstract
Abstract An adjustable tensioning and retaining device particularly well suited for supporting a filter bag in a gas filtering baghouse includes an elongated linking member interconnected to one end of the filter bag, a wedge shaped body member having a sloping top surface with a plurality of spaced apart indentations formed in this sloping top surface, and coupling means for removably connecting the linking member into any of the indentations in the body member. In addition, the wedge shaped body member is mounted to a supporting structure in the filtering baghouse for linear movement such that the plane of the sloping top surface of the body member is inclined to the direction of linear movement.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
An adjustable tensioning and retaining device for holding fast a filter bag in a baghouse apparatus, the adjustable tensioning and retaining device comprising: an elongated linking member adapted to be connected to the filter bag; a body member having a plurality of spaced indentations, the body member is wedge shaped with a sloping top surface and the indentations are formed in the sloping top surface; means for mounting the body member to a supporting member for linear movement of the body member along the supporting member so that the plane of the sloping top surface of the body member containing the indentations is inclined to the direction of linear movement of the body member; and, coupling means for removably connecting the linking member into any one of the indentations of the body member.
Claim 2
Dependent Claim
133 words
An adjustable tensioning and retaining device for holding fast a filter bag in a baghouse apparatus, the adjustable tensioning and retaining device comprising: an elongated linking member adapted to be connected to the filter bag; a body member having a plurality of spaced indentations, the body member is wedge shaped with a sloping top surface and the indentations are formed in the sloping top surface; means for mounting the body member to a supporting member for linear movement of the body member along the supporting member so that the plane of the sloping top surface of the body member containing the indentations is inclined to the direction of linear movement of the body member; and, coupling means for removably connecting the linking member into any one of the indentations of the body member.
Claim 3
Dependent Claim
44 words
The adjustable tensioning and retaining device of claim 1 wherein the body member is formed with an aperture therethrough with the minor vertical axis of the aperture perpendicular to the direction of linear movement of the body member to receive the linking member therethrough.
Claim 4
Dependent Claim
93 words
The adjustable tensioning and retaining device of claim 2 wherein: the aperture through the body member is an elongated slot with its major horizontal axis disposed in the direction of linear movement of the body member and dividing the indentations into two parallel rows of paired indentations with the indentations of a pair being aligned on opposite sides of the slotted aperture; the longitudinal axes of the indentations are substantially perpendicular to the major axis of the slotted aperture through the body member; and, the coupling means engage into any pair of indentations.
Claim 5
Dependent Claim
31 words
The adjustable tensioning and retaining device of claim 3 wherein the slotted aperture through the body member is open at one of its ends to one end of the body member.
Claim 6
Dependent Claim
56 words
The adjustable tensioning and retaining device of claim 1 wherein: the elongated linking member has a plurality of apertures spaced apart along its length; and, the coupling means comprises pin means removably received through any one of the apertures in the elongated linking member and removably engaging any one of the indentations in the body member.
Claim 7
Dependent Claim
33 words
The adjustable tensioning and retaining device of claim 5 wherein the vertical distance between successive indentations in the body member is less than the centerline distance between successive apertures along the linking member.
Claim 8
Dependent Claim
18 words
The adjustable tensioning and retaining device of claim 1 further comprising resilient means connected to the linking member.
Claim 9
Dependent Claim
40 words
The adjustable tensioning and retaining device of claim 1 wherein: the coupling means comprises pin means attached to and projecting from opposite sides of the elongated linking member for removably engaging any one of the indentations in the body member.
