DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] In one of the many preferred embodiments of the invention, a spring seat apparatus is configured to receive universal adapter plates to which compression springs are secured. The universal adapter plates can be slid horizontally away from the vibratory screen machine. As a result, the vibratory screen machine does not have to be lifted high enough for the compression springs to be removed by vertically.

[0021] Referring to FIG. 3, an apparatus 100 of the present invention is shown generally. The apparatus 100 includes a step-down spring seat assembly 102 configured to be secured to a vibratory screen machine. One or more universal adapter plate assemblies 104 can be secured to a top surface of the step-down spring seat assembly 102. One or more compression springs 106 can be secured to the step-down spring seat assembly 102 by placing the compression springs 106 on the universal adapter plate assemblies 104. One or more universal adapter plate assemblies 108 can be positioned between the compression springs 106 and a top adapter plate assembly 110, which is configured to be secured to a vibratory screen machine. A spring seat base 112 can be attached to a side of the step-down spring seat assembly 102.

[0022] As shown more clearly in FIG. 4, one or more universal adapter plate assemblies 104 optionally but preferably are secured to a top surface of the step-down spring seat assembly 102, which is configured to receive the universal adapter plate assemblies 104. One or more spring seat bases 112 can be detachably connected to the step-down spring seat assembly 102 in front of each of the compression springs 106. The spring seat bases 112 provide a stable platform on which to work once the compression springs 106 are removed, preferably slidably, from the step-down spring seat assembly 102. One or more spring guide castings 220 are positioned atop and connected to the one or more universal adapter plate assemblies 104 secured to the top surface of the step-down spring seat assembly 102. One or more compression springs 106 are positioned atop the one or more spring guide castings 220, and one or more spring guide castings 230 can be positioned above a center opening in the one or more compression springs 106. One or more universal adapter plate assemblies 108 can be connected to the spring guide castings 108 positioned above the center opening in the one or more compression springs 106. A top adapter plate assembly 110 can be connected to the one or more universal adapter plate assemblies 108 positioned above the one or more compression springs 106, wherein the top adapter plate assembly 110 is configured to be secured to a vibratory screen machine.

[0023] FIG. 5 shows an apparatus 100 with clear compression springs 106 to show more clearly the connection of the spring guide castings 220 to the universal adapter plate assemblies 104. The universal adapter plate assemblies 104 are secured to a top surface of the step-down spring seat assembly 102, which is configured to receive the universal adapter plate assemblies 104. One or more spring seat bases 112 can be detachably connected to the step-down spring seat assembly 102 in front of each of the compression springs 106. The spring seat bases 112 provide a stable platform on which to work once the compression springs 106 are removed, preferably slidably, from the step-down spring seat assembly 102. One or more spring guide castings 220 are positioned atop and connected to the one or more universal adapter plate assemblies 104 secured to the top surface of the step-down spring seat assembly 102. One or more compression springs 106 are positioned atop the one or more spring guide castings 220. A top adapter plate assembly 110 is connected to the compression springs 106 via one or more universal adapter plate assemblies 108 positioned above the one or more compression springs 106.

[0024] As shown in FIG. 6, the step-down spring seat assembly 102 is configured to be secured to a vibratory screen machine. The apparatus 100 of the present invention can be used to more easily replace the compression springs 106 that are an integral part of the vibratory screen machine. The spring seat bases 112 can be connected to the step-down spring seat assembly 102 be placing the arms extending from the spring seat bases 112 in the slots in the side of the step-down spring seat assembly 102. The spring seat bases 112 provide a stable platfoiiii onto which the compression springs 106 can be slid for removal and/or repair. The universal adapter plate assemblies 104, 108 can be disconnected from the step-down spring seat assembly 102 and top adapter plate assembly 110 and slid horizontally onto the spring seat bases 112. The springs can then be removed and replaced by disconnecting the spring guide castings 220, 230 from the universal adapter plate assemblies 104, 108, respectively. Once new compression springs 106 are installed, the apparatus 100 can be re-assembled and installed back on to the vibratory screen machine.
