Abstract
Abstract A collecting electrode plate assembly for a flow-through housing of an electrical precipitator wherein each collecting electrode is made up of aligned panels interconnected by guide arrangements spanning the junctures of the adjacent panels. Each guide arrangement includes a pair of opposing plates secured to one of the panels and outwardly embracing an adjacent panel to accommodate relative lateral movement between adjacent panels while retaining the panels in a common plane.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
176 words
A collecting electrode plate assembly for a flow-through housing of an electrostatic precipitator, comprising: a collecting electrode; electrode suspension means adapted to be supported by the housing of the precipitator; said collecting electrode including a plurality of successively aligned similar panels pivotally suspended from said suspension means and spaced apart one from the other for swinging movement of said panels during electrode cleaning operations; said panels each including a pair of spaced edge beam members and a central web portion extending between and connecting said beam members; guide means at each juncture of said successive panels including a pair of guide plates disposed in opposed spaced relation on either side of the panels and spanning a respective pair of opposing edge beam members; slot means in one of said opposing edge beam members associated with each of said plates; and said plates each including a protruding clip portion removably positioned and contained within an associated slot means to mechanically secure the plate to said beam member, thereby aligning and retaining the panels in a common plane.
Claim 2
Dependent Claim
176 words
A collecting electrode plate assembly for a flow-through housing of an electrostatic precipitator, comprising: a collecting electrode; electrode suspension means adapted to be supported by the housing of the precipitator; said collecting electrode including a plurality of successively aligned similar panels pivotally suspended from said suspension means and spaced apart one from the other for swinging movement of said panels during electrode cleaning operations; said panels each including a pair of spaced edge beam members and a central web portion extending between and connecting said beam members; guide means at each juncture of said successive panels including a pair of guide plates disposed in opposed spaced relation on either side of the panels and spanning a respective pair of opposing edge beam members; slot means in one of said opposing edge beam members associated with each of said plates; and said plates each including a protruding clip portion removably positioned and contained within an associated slot means to mechanically secure the plate to said beam member, thereby aligning and retaining the panels in a common plane.
Claim 3
Dependent Claim
23 words
The assembly according to claim 1, and said guide means including a plurality of said plates spaced along the length of each panel.
Claim 4
Dependent Claim
33 words
The assembly according to claim 1, and said panels each being of a generally channel shaped configuration with the channel openings of successive panels alternately opening to either side of the collecting electrode.
Claim 5
Dependent Claim
20 words
The assembly according to claim 1, and said central web portions of the panels being disposed in a common plane.
Claim 6
Dependent Claim
72 words
The assembly according to claim 1, and each of said plates including a central attachment portion overlapping the respective beam member including its associated slot means and a retaining flange extending laterally therefrom and overlapping the opposing beam member; and said clip portion protruding from said central attachment portion along the length of the panel and extending through said slot means to releasably enclasp said beam member and secure the plate thereto.
Claim 7
Dependent Claim
25 words
The assembly according to claim 1, and tab means interconnecting said plate and beam member to retain said clip portion in the plate securing position.
Claim 8
Dependent Claim
41 words
The assembly according to claim 1, and said beam member including said slot means having an outwardly positionable tab generally longitudinally aligned with said clip portion and engageable with said plate to retain the clip portion in the plate securing position.
Claim 9
Dependent Claim
71 words
The assembly according to claim 1, and each of said beam members including a pair of laterally extending wall sections in opposing spaced relation on either side of said central web portion, a transverse edge wall portion extending between and connecting said lateral wall sections to define one edge of the panel, and a connecting wall extending laterally and inwardly from one of said wall sections to said central web portion.
Claim 10
Dependent Claim
109 words
The assembly according to claim 8, and each of said plates being of a stamped integral construction including a central attachment section substantially spanning the breadth of the wall section of the respective beam member including its associated slot means, a laterally extending retaining flange section outwardly offset from said attachment section and overlapping the wall section of the opposing beam member, and a rigidifying bent portion connecting said attachment and retaining flange sections; and said clip portion protruding from said attachment section through said slot means and enclasping the wall section of the respective beam member including said slot means to secure the plate to said beam member.
Claim 11
Dependent Claim
87 words
The assembly according to claim 8, and each of said plates including a central attachment portion overlapping the wall section of the respective beam member including its associated slot means and a retaining flange extending laterally therefrom and overlapping the wall section of the opposing beam member; said slot means including a pair of slots in said wall section sized to receive said clip portions; and said clip portions extending through said slots to releasably enclasp said wall section to secure the plate to said beam member.
Claim 12
Dependent Claim
40 words
The assembly according to claim 10, and said wall sections including a tab proximate each of said slots, and each of said tabs being selectively cooperative with said slots and clip portions to affix the plate to said beam member.
