Abstract: An adzer bit includes a support member that defines a through hole that is configured to receive a fastener. The support member includes a cap portion and a base portion. The support member also defines an annular slot that is axially disposed between the cutting segment cap portion and the base portion. A plurality of cutting segments are received and secured in the annular slot. The material of the plurality of cutting segments is harder than the material of the support member.

Abstract: A spike claw puller for pulling a rail spike includes a handle that defines a through hole that is hole configured to couple to a rail spike pulling machine. A body section defines a top surface and comprises first and second feeder teeth that extend from the handle at a first lift and form a jaw opening therebetween configured to receive the rail spike. First and second feeder extensions extend from the first and second feeder teeth, where the first and second feeder extensions extend beyond a plane that is coplanar with the top surface. The first and second feeder extensions facilitate alignment with the rail spike.

Abstract: A spike claw puller for pulling a rail spike has a handle a first feeder tooth and a second feeder tooth. The handle includes a feature for coupling the spike claw puller to a rail spike pulling machine. The first and second feeder teeth extend from the handle and form a jaw opening therebetween to receive a rail spike. The first feeder tooth includes a first feeder extension and the second feeder tooth includes a second feeder extension to help align the spike claw puller with the rail spike.

Abstract: A stabilizer is disclosed for use in stabilizing and maintaining the spacing between a pair of railway rails during rail tie replacement. The stabilizer comprises a rod having a length and a pair of ends. A pair of rail clamps is carried by the rod, and each clamp is configured to engage one of the rails and secure the rail relative to the rod. An expanding member is carried by the rod and configured to selectively expand along the length of the rod between its ends to engage a structure proximal to the rails, wherein, upon engagement of the rails by the rail clamps and the expanding member with the structure, the rails are maintained in substantially fixed relationship to each other and to the structure, but are free to be moved vertically relative to the structure.

Abstract: A stabilizer assembly for use in an extruder having a screw rotating in a barrel is provided. The assembly comprises a plurality of rods that are secured to an interior of the barrel at one end. Each of the rods has an end that extends radially inwardly toward the center of the barrel. On the discharge end of the screw, there is a bearing member that is in contact with each of the opposite ends of the rods. The rods support the discharge end of the screw and stabilize its rotation in the barrel.

Abstract: A method of extending the life of an extruder screw by affixing tiles of wear-resistant material along the crest of the extruder screw flighting threads, and optionally grinding the hardened material to remove any sharp edges. In another configuration of the present invention, plates of wear-resistant material are secured to the leading edges of the extruder screw threads to further prolong the life of the extruder screw.

Abstract: A die assembly and a process for using the die assembly is disclosed. The die plate is made of a material that is somewhat resistant to cracking when subjected to pressure of an extrudate material from behind the die assembly. A series of recesses are arranged about the circumference of the die plate, into which dies of a more hardened material are secured. Holes conforming to the shape of the desired extrudate are drilled through the die plate and dies. The surface of the dies is ground smooth so that there is consistent, even contact between the dies and the mechanism used for cutting the extrudate as it is pushed out of the holes in the dies.

Abstract: A modular base is provided. A plurality of motor support members are secured to one another by a first linking member. Each motor support member has a mounting surface that is adapted to be secured to a motor, and the first linking member has a central axis and is dimensioned to support the motor. A plurality of extruder support members are secured to one another by a second linking member. Each extruder support member has a carriage that is adapted to be secured to an extruder, wherein the second linking member has a central axis and is dimensioned to support the extruder. An intermediate member having a mounting surface that is adapted to be secured to a transmission is provided.

Abstract: An extruder that is adapted to provide a flow of an extrudate is provided. There is a frame having a plurality of storage positions, a discharge position and a plurality of extruder heads. Each extruder head is secured to the frame and is movable between one of the storage positions and the discharge position. A sealing member is provided that is secured to the extruder. The sealing member is adapted to move between an engaged position and a disengaged position, wherein the sealing member moves from the disengaged position to the engaged position so as to engage one of the extruder heads when it is in the discharge position.

Abstract: An improved extrusion assembly is disclosed which better adapts to thermal changes resultant from the transport of high-temperature extrudate. An extrusion screw present in the assembly includes a hollow portion. A biasing member is disposed in the hollow portion. When the assembly is transporting high-temperature extrudate, the biasing member's included Belleville washer component compensates for the thermal expansion and contraction of the extrusion screw.

Abstract: A rotating cutting apparatus comprising a cutting blade holder with at least one hole on the outside diameter of the cutting blade holder into which cutting blades are inserted and bonded to the cutting blade holder. The cutting blade holder encloses a center hole, so that the rotating cutting apparatus can be mounted to a drive shaft of machinery or secured to a cup that can be mounted to the drive shaft of machinery and driven by the machinery. The cutting blade holder can be made of a less expensive material, with only the cutting blade being made of higher-grade materials that maintains its cutting edge well. Additionally, in some arrangements of the present invention, the cutting blade may be sharpened on two sides so that the rotating cutting apparatus can be used for longer periods of time.

Abstract: There are a number of applications today where the pumping of abrasive slurries is necessary. The pumping mechanisms, though, can be complex, employing multiple transfer cylinders and movable pipes. These designs have their problems, specifically wear between poorly sealing surfaces. To reduce this problem, seals are provided that have multiple wear surfaces which include harder tiles secured over a softer core to benefit from the relative hardness or flexibility of each of the respective materials.
