The Liberator Master Bill of Materials

This is the complete materials list for the machine that we are building for Factor e Farm use:

This is a functionally-descriptive list of the materials, with a summarized parts and cut list at the end.

Frame

Main Frame

Exact length is determined by the mounting of the cylinder.

• 6" wide structural u-channel - 7/16" thick, 13 lb per foot weight - one 20 foot long stick

Main Frame Fasteners

These are the 1/2" bolts that hold the desing-for-disassembly frame together.

Cylinder Alignment Guides

This includes the mechanism for using 4 bolts to align the main cylinder from 4 sides, so that the press foot does not rub on the sides of the compression chamber.

Soil Blocks

These are blocks under the hopper interface plate which prevent soil from falling out the sides of the compression chamber, since the hopper interface aperture is larger than the 6"x12" throat of the machine.

Arms

These are the primary arms, which attach to the main frame, and the secondary arms, which attach to the primary arms.

Legs

This includes the [4] legs, leg holders on the secondary arms, and clamp bolt assembly for adjusting the legs.

Feet

These are the [4] feet, including the clamp bolt assembly for attaching the feet to the legs.

Table

These are the [3] one-foot wide surfaces upon which the soil drawer moves, preventing bricks or soil from dumping to the ground.

Drawer

This is the device that moves horizontally to load soil into the compression chamber and to eject finished bricks from the machine.

Drawer Cylinder

This includes the drawer cylinder, hydrauilic fittings, mounting, and hoses up to the solenoid valve.

Drawer Sensor Assembly

This includes the sensor, wire, and sensor mounting to arms, plus the surface for attaching the sensor magnets.

Main Cylinder

This includes the main cylinder, fittings, and hoses up to the solenoid valve.

Press Foot

This includes the parts mounting on top of the cylinder rod, which transfer the pressing force to the brick.

Main Cylinder Sensor Assembly

This includes the main sensor with wire leading to the control box, its attachment to the frame, as well as the sensor magnet attachment surface, its connection to the bottom of the press foot, and the magnets.

Hopper Interface Plate

This is a heavy plate that bolts to the top of the frame with [4] 3/4" bolts, with [6] welded hinges for attaching the hopper, minus the nuts attached to the main frame, into which the interface plate bolts. The plate has a rectangular aperture cut in it for the soil to fall into the compression chamber.

Hopper

The hopper consists of 4 trapezoid-like pieces, with 3 bolts welded to the side edges to accommodate closure via the Hopper Edge Seals. These are bolted to the hopper interface plate

• 1/8" sheet steel - 1.5 sheets of 4'x8' steel

Hopper Edge Seals

These are long, hinged pieces of metal that close any gaps in the hopper, and because they are bolted to the hopper for structural integrity - they allow the hopper to be design-for-disassembly. The hinges have a 3/4" hole on one side, for bolting through, while giving slight play to adjust misalignment.

• 1/8"x2" flat, 13 feet - $8.45, Sweiger
• 1/8"x3" flat, 13 feet - $12.35, Sweiger
• [12] door hinges - $12, Restore

Hopper Shaker

The hopper shaker is an assembly consisting of a hydraulic motor with an eccentric for vibratory action, plus a support member for triangular attachment.

• Hydraulic motor -
• 2 1" bearings -
• Keyed shaft - 1"x, 1/4"? keyway
• Key - 1/4"
• Eccentric
• 4 bolts, 3/8"x , 4 lock washers, 4 lock nuts,
• 2 bolts, 1/2"x , 2 washers, 2 lock washers, 2 lock nuts

Electronics

Enclosure Box

• Box - Cutler and Hammer, product ID

Sensors

This is the assembly that includes the magnetic Hall Effect sensor, its encapsulation, and wire going up to the conroller box connection.

Controller

This is everything inside the controller, minus sensors, solenoid power leads, and main power cord - which plug into the controller through standard knockouts in the enclosure box.
