Abstract
Abstract A finger assembly for use in a packer grid wherein the finger assembly comprises a body having an upper frustoconical section having at least one flat thereon. At least one flexible finger extends downwardly and outwardly from the body. The finger includes an upper portion which is positioned against the flat. The upper portion also includes at least one ear. A cap is attached to the upper portion of the body and holds the upper portion of the finger against the flat. The cap also includes a circumferential groove in its interior surface into which the ear extends to prevent withdrawal of the finger when the cap is tightened.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
98 words
A finger assembly for use in a packer grid, said finger assembly comprising: a. a body having an upper frustoconical section having at least one flat thereon; b. at least one flexible finger extending downwardly and outwardly from said body, said finger having an upper portion positioned against said flat, said upper portion having at least one ear extending therefrom; and c. cap means attached to said body for holding the upper portion of said finger against said flat, said cap having a circumferential groove in its interior surface, the ear of said finger extending into said groove.
Claim 2
Dependent Claim
98 words
A finger assembly for use in a packer grid, said finger assembly comprising: a. a body having an upper frustoconical section having at least one flat thereon; b. at least one flexible finger extending downwardly and outwardly from said body, said finger having an upper portion positioned against said flat, said upper portion having at least one ear extending therefrom; and c. cap means attached to said body for holding the upper portion of said finger against said flat, said cap having a circumferential groove in its interior surface, the ear of said finger extending into said groove.
Claim 3
Dependent Claim
17 words
The finger assembly of claim 1 further including means for adjustably mounting said body on the grid.
Claim 4
Dependent Claim
34 words
The finger assembly of claim 1 wherein there are four flats equally spaced about the perimeter of said frustoconical section and four flexible fingers, each being associated with a different one of said flats.
Claim 5
Dependent Claim
44 words
The finger assembly of claim 1 wherein said upper section has two slots therein which intersect each other at 90°, said slots extending diametrically across said upper section, the ends of each slot adapted to receive an upper portion of a flexible finger member.
Claim 6
Dependent Claim
49 words
The finger assembly of claim 4 wherein said body has a generally cylindrical bottom portion, a frustoconical midportion, and an upper portion, said upper portion including said upper frustoconical section and a lower cylindrical portion, said lower cylindrical portion being connected to the smaller end of said frustoconial midportion.
Claim 7
Dependent Claim
39 words
The finger assembly of claim 5 wherein said bottom portion has a slot therein extending diametrically thereacross, the midplane of the slot in said bottom being coplanar with the midplane of one of said slots in said upper section.
Claim 8
Dependent Claim
149 words
A packer grid comprising: a. a frame including two spaced apart members extending perpendicular to the packer flow; b. a plurality of parallel elongated mounting bars, each having its ends adjustably connected to said spaced apart members, and extending generally perpendicularly to said spaced apart members; and c. a plurality of finger assemblies adjustably and removably mounted on said mounting bars, each finger assembly including: i. a body having an upper frustoconical section having at least one flat thereon; ii. at least one flexible finger extending downwardly and outwardly from said body and having an upper portion positioned against said flat, said upper portion having at least one ear extending therefrom; and iii. cap means attached to said body for holding the upper portion of said finger against said flat, said cap having a circumferential groove in its interior surface, the ear of said finger extending into said groove.
Claim 9
Dependent Claim
149 words
A packer grid comprising: a. a frame including two spaced apart members extending perpendicular to the packer flow; b. a plurality of parallel elongated mounting bars, each having its ends adjustably connected to said spaced apart members, and extending generally perpendicularly to said spaced apart members; and c. a plurality of finger assemblies adjustably and removably mounted on said mounting bars, each finger assembly including: i. a body having an upper frustoconical section having at least one flat thereon; ii. at least one flexible finger extending downwardly and outwardly from said body and having an upper portion positioned against said flat, said upper portion having at least one ear extending therefrom; and iii. cap means attached to said body for holding the upper portion of said finger against said flat, said cap having a circumferential groove in its interior surface, the ear of said finger extending into said groove.
Claim 10
Dependent Claim
70 words
The packer grid of claim 7 wherein the body of each finger assembly includes four flats equally spaced about the perimeter of said frustoconical section, and four flexible fingers, each being associated with a different one of said flats, said fingers extending downwardly from said body and away from said body in a direction having an angle of generally 45° with respect to axis of elongation of said mounting bars.
Claim 11
Dependent Claim
58 words
The packer grid of claim 7 wherein the body of each said finger assembly has a slot in its bottom surface extending diametrically thereacross, said finger assembly being mounted on said mounting bar with said bar being received within said slot, and a retaining member removably connected to said body for clamping said finger assembly to said bar.
Claim 12
Dependent Claim
61 words
The packer grid of claim 7 further including a track member mounted adjacent the upstream end of said grid and extending parallel to said spaced apart members, and at least one finger member adjustably mounted on said track and extending downwardly from the track between two adjacent mounting bars and forwardly from said track toward the downstream end of said grid.
