An enhanced split cooling system for a turbocharger and an engine includes an oil cooler, a three-way valve assembly and a four-way valve assembly for controlling the flow of coolant, and radiators and subcoolers, for controlling coolant temperature. The valve assemblies are independently controllable to direct coolant through an oil cooler and a turbocharger intercooler either directly from the engine if the oil cooler and intercooler require heating or from the radiators and subcoolers if the oil cooler and intercooler require cooling. Depending upon the engine operating temperature, the valve assemblies can be configured to establish at least three different coolant processing modes.

Enhanced split cooling system

An improved radiator assembly for supporting a cooling core has first and second push pads positioned contiguous to the opposite sides of the cooling core. The push pads have spaced apart slots therein. First and second side rails are positioned contiguous to the first and second push pads. The side rails have spaced apart tabs that extend within the push pad slots. The slots are of greater longitudinal dimension than the tabs thereby permitting the push pads to move longitudinally relative to the side rails. A plurality of tie rods extend between the side rails to hold the side rails and thereby the radiator assembly together.

Radiator assembly

The present invention is a pair of split dies comprises of a pair of fixed die halves, with each fixed die half having an associating movable die insert. The pair of split dies are separated from each other in order to admit a cutting blade therebetween and a variable width opening is formed between each of the fixed die halves and their associating movable die inserts. The movable die inserts move toward the fixed die halves and thereby decrease the width of the openings in response to cam means attaching to the blade which engage movable cam tracks located on the movable die inserts opposite the openings. The openings close on tubing located within the openings so that the tubing is held stationary on either side of where the blade cuts the tubing. The movable die inserts move away from the fixed die halves and thereby increase the width of the openings in response to disengagement with the cam means. When the cam means are disengaged from the movable die inserts, die springs located in spring pockets provided in the fixed die halves push the movable die inserts away from the fixed die halves, thus releasing the tubing and allowing it to move quickly through the openings as the dies are repositioned on the tubing for the purpose of making another cut.

The present invention is a control device that allows an operator to partially open a gate valve found at the bottom of a railway freight car hopper in order to obtain a sample of a flowable particulate or granular product contained within the hopper but preventing the gate valve from fully opening so as to partially unload the hopper. The device is provided with a rotatable operating shaft having attaching to it a structure for opening and closing the gate valve in response to rotation of the operating shaft. The operating shaft is provided with two ends that extend through end panels of the hopper. One of the two ends is provided with a lockable sample control handle and the second of the two ends is provided with an angled slot by which a lockable control handle movably attaches. The angled slot allows the operating shaft to be rotated when the control handle is locked closed by unlocking and turning the sample control handle. The limited rotation of the operating shaft allowed by the angled slot is sufficient to partially open the gate valve in order that the sample be obtained. However, the gate valve cannot open fully as long as the control handle is locked closed because the angled slot limits rotation of the operating shaft.

End cap gate sampling device

Rail hopper cars have loading gates which is a way of controlling the flow of material that is in hopper cars out through a connection tube. There are control rods for opening and closing the loading gate. There is an end cap that fits over the open end of the connection tube. The cap, in the present invention, has outwardly extending radially spaced locking lugs each having a locking convex surface. A separate locking lug concave surface is positioned on each handle of the control rods for mating with the convex surfaces on the cap. When the end cap is placed over the tube and is rotated to a position where the locking convex surfaces are adjacent the locking lugs on the operating handles of the control rods, the control rod handles cannot turn. Also when in this position the locking lugs on the handles prevent the cap from being removed. A spring loaded locking lever on the end cap engages a locking slot on the end tube and prevents rotation of the end cap when it is positioned thereon. When it is desired to remove the end cap, the spring loaded locking lever is removed from the locking slot and the end cap rotated about 40 degrees to where the locking lugs thereon are out of alignment with the locking lugs on the control rod handles. The cap can be readily removed and the control rod handles are then operable.

A hopper with a bottom discharge slot and valving comprising plates slidably supported beneath the slot and movable between closed and open positions, said plates having a plastic flexible covering to facilitate movement in shear against the load of the particulate material bearing thereagainst.

A device for maintaining the proper lateral position of brake shoes with respect to the wheels of a locomotive. An adjusting bar is used to adjust the distance between the pull rod of the brakes and a bracket supported by the safety strap. A supporting axle has a locomotive wheel on each end so that there is a wheel on each rail. Each wheel has a brake which is provided with an adjuster bar. There is thus a left and a right adjuster bar. A tie bar extends from the left adjuster member to the right adjuster member to keep the brake shoes aligned with the respective wheels after there is wear in the various linkage connections.

An improved frame assembly for holding radiator heat exchanger core units required for cooling engines such as the locomotive engine. There are specially designed side frames on each side of the cooling core with special push-pad units between the side rail and the core. The push-pads include fixed sections which are fixed with respect to the side frame and movable sections which are movable therewith to provide for unequal expansion of the side frame and the core.

This is a process relating to improvements in the soldering of headers to conventional radiators. Tubular members of the radiator extend through holes in the header. The tubes are initially sealed to the header with a solder having a high temperature melting point T.sub.1. Infrared heat heats the header to a temperature T.sub.2 which is less than T.sub.1 but above a lower temperature T.sub.3 which is the melting temperature of a second solder. Upon the header reaching a selected temperature T.sub.2, a selected amount of the second solder in a molten state is poured in the header to puddle the entire pan area of the header, and allowed to cool to form a very strong soldered connection.
