Abstract
Abstract A multi-functional linear motion shaker includes a rectangular outer support frame with a tank, often referred to as a "possum belly", for receiving the incoming drilling fluid flow. A set of adjustable louvers and a tray is positioned on the side of the tank. The adjustable louvers and tray serve to screen out the larger and stickier drill cuttings or solids. A vibrating deck assembly is positioned within the outer support frame adjacent the tank and tray assembly. The vibrating deck assembly is of a double deck design whose upper and lower decks include cross members to support the mud screens. The upper and lower decks are vertically spaced apart and connected together into one unit by vertical structural members. A moveable plate is positioned on the upper deck adjacent the adjustable louvers and tray. This moveable plate can be positioned to direct drilling fluid flow to the upper deck or repositioned to redirect fluid flow to the lower deck and bypass the upper deck. The moveable plate allows the shaker to function as a multi-functional linear motion shaker which allows configuration of the shaker as a single or double deck flowline shaker, as a drying shaker or as a combination simultaneous flowline shaker and drying shaker. The multi-functional linear motion shaker allows easy replacement of upper or lower screens independently of one another when used in a double deck shaker configuration.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
A linear motion shaker used in oil and gas drilling operations which is configurable as a flowline shaker or as a combination simultaneous flowline shaker and drying shaker, said linear motion shaker comprising: a carriage support frame, a bed frame supporting an upper deck and a lower deck in a spaced vertical relationship, said bed frame supported within said carriage frame, a means for imparting vibratory motion to said bed frame, a drilling fluid inlet tank attached to said carriage frame and adjacent said upper deck and said lower deck, said drilling fluid inlet tank configured to direct drilling fluid flow onto said upper deck, and said upper deck including means for diverting said drilling fluid flow directly to said lower deck and thereby bypassing said upper deck to allow isolation of independent drilling fluid flows to each of said upper deck and said lower deck.
Claim 2
Dependent Claim
146 words
A linear motion shaker used in oil and gas drilling operations which is configurable as a flowline shaker or as a combination simultaneous flowline shaker and drying shaker, said linear motion shaker comprising: a carriage support frame, a bed frame supporting an upper deck and a lower deck in a spaced vertical relationship, said bed frame supported within said carriage frame, a means for imparting vibratory motion to said bed frame, a drilling fluid inlet tank attached to said carriage frame and adjacent said upper deck and said lower deck, said drilling fluid inlet tank configured to direct drilling fluid flow onto said upper deck, and said upper deck including means for diverting said drilling fluid flow directly to said lower deck and thereby bypassing said upper deck to allow isolation of independent drilling fluid flows to each of said upper deck and said lower deck.
Claim 3
Dependent Claim
82 words
A linear motion shaker used in oil and gas drilling operations which is configurable as a flowline shaker or as a combination simultaneous flowline shaker and drying shaker according to claim 1 wherein: said upper deck includes a mesh screen for separating solids from said drilling fluid flow, said lower deck includes a mesh screen for separating solids from said drilling fluid flow, and the area of said upper deck screen and the area of said lower deck screen being substantially equal.
Claim 4
Dependent Claim
61 words
A linear motion shaker used in oil and gas drilling operations which is configurable as a flowline shaker or as a combination simultaneous flowline shaker and drying shaker according to claim 2 wherein: said bed frame includes laterally disposed access openings adjacent said lower deck to allow replacement of said lower deck mesh screens independently of said upper deck mesh screens.
Claim 5
Dependent Claim
45 words
A linear motion shaker used in oil and gas drilling operations which is configurable as a flowline shaker or as a combination simultaneous flowline shaker and drying shaker according to claim 3 wherein: said means for diverting said drilling fluid flow is a moveable plate.
Claim 6
Dependent Claim
78 words
A linear motion shaker used in oil and gas drilling operations which is configurable as a flowline shaker or as a combination simultaneous flowline shaker and drying shaker according to claim 4 wherein said means for imparting vibratory motion to said upper deck and said lower deck includes: a pair of counter rotating vibrator motors, a motor support frame attached to said bed frame, and said pair of counter rotating vibrator motors mounted on said motor support frame.
Claim 7
Dependent Claim
47 words
A linear motion shaker used in oil and gas drilling operations which is configurable as a flowline shaker or as a combination simultaneous flowline shaker and drying shaker according to claim 5 including: a means for isolating vibratory motion of said bed frame from said carriage frame.
Claim 8
Dependent Claim
85 words
A linear motion shaker used in oil and gas drilling operations which is configurable as a flowline shaker or as a combination simultaneous flowline shaker and drying shaker according to claim 6 wherein said means for isolating vibratory motion of said deck frame from said shaker support frame includes: a spring positioned at each corner of said bed frame, said springs supporting said bed frame within said carriage frame, and said springs allowing vibratory motion of said bed frame with respect to said carriage frame.
Claim 9
Dependent Claim
65 words
A linear motion shaker used in oil and gas drilling operations which is configurable as a flowline shaker or as a combination simultaneous flowline shaker and drying shaker according to claim 7 including: an angle adjustment means disposed on said carriage frame, and said angle adjustment means cooperating with said springs and said bed frame to allow adjustment of the angle of said bed frame.
