Rail car door opener and closer

Abstract

The embodiment of the present invention is a door closer and opener for rail cars with the doors disposed on the bottom of the rail car and a wayside tool called a door tool this invention that is predisposed at a rail road unloading site where various commodities that are unloaded. The invention allows a technician to open and close rail car doors with members in said invention. The invention reduces the labor and physical effort required by humans. The invention assist a human and is controlled by a human to open said doors. The invention opens and closes a variety of rail car doors as stated in the illustrations with multiple members of said invention The motive force is preferred to be hydraulic but not limited to hydraulic.

1 . What is claimed is a door opener/closer with members  101  and  102  that when pulled together create a squeezing together of the rail car doors of a rail car with bottom doors disposed below the rail car via the members that transmit that force  104 , 106  and  103 . 
 What is claimed is a door opener/closer with a multifaceted articulation assembly as described in  FIGS. 2A-2C  and a integrated tool holder for the fitting of many tools described in the illustrations to open and close various door locks of a rail car.    What is claimed is a door closer with swing arms that swing in from the side of a rail car between open doors of a rail car and a movement together of the swing arms transmits a force to close the doors double doors.    What is claimed is a door closer with swing arms that swing in from the side of a rail car between open doors of a rail car and a movement together of the swing arms transmits a force to close the single doors.    What is claimed is a set of swing arms that move independently and or together in a synchronous motion along a suspended beam and are attachabley secured to traversing member where traversing member is motored to roll via rollers along a suspended beam to position the opener or closer assemblies. And further claimed the swing arms  106  swing in and out to move  103  outside the car to move to another door around the car and then to swing back in towards the car to reposition  103  to move into the door and said resultant movement closing the door.    What is claimed is a swing arm with its members that close doors    What is claimed is a swing arm that has a member  103  that can be positioned at various positions from outside the rail car to under the car with a inward or outward movement of the swing arms  106 . And further claimed that the  103  member can act as a opener to a modified wine door latch that is modified with a horizontal stud attachabley secured to the wine door latch and protrudes horizontally out and from the latch and at a right angle from the latch to provide a modified wine door latch with a contact member that  103  can now be positioned to contact stud at the slide rail area of  103  and a traversing movement of the  102  member in the direction required to slide stud up the rail thus lifting the latch to open the doors of said rail car.    What is claimed is a opener assembly for opening wine door lock mechanisms. And further claimed members of said assembly rotate a safety cam to the unlocked position as described in the illustrations and further claimed that a swing arm  405  with contacts at the furthermost point of contact to the latch to have maximum leverage over the latch of a wine door lock. And further claimed that the silhouette design of the wine door lock opener assembly is novel for docking the opener to the wine door lock    What is claimed is a too attachable to opener member depicted in  FIGS. 2A-2C  for the opening and closing of a miner type door. And further claimed that said movement of  206  with attachment depicted in  FIG. 5D  articulates the insertion of bar  503  in to cavity  501  and further claimed that after insertion of  503  the crank type rotation of  208  unlocks the door opening of a miner type lock and further claimed that insertion of  503  as stated in to  502  positions opener assembly to rotate  502  and the resultant rotation opens or closed the door depending on the rotation cw or ccw selected by the operator.    What is claimed is a tool attachment and attachable to opener member depicted in  FIGS. 2A-2C  a tool for rack and pinion type doors where the rotation of hub depicted in  FIG. 3C   301  is accomplished by the extension of  208  causing  302  to insert into square cavity of  301  and further claimed that once positioned the crank like rotation of  208  as described creates a resultant rotation of hub  301  opening the doors or closing the doors as said rotation is selected by operator of said opener/closer. And further claimed that limited rotation of  302  within its member via a transmitted force of torsional vibration created by the impact wrench  303  creates vibrations that assist in rotation corroded and or stuck rack and pinion door gears while  208  applies a constant force of torque applied via motor  207 , and further claimed that the combination of constant torque and vibrational torque applied together in either direction of rotation are superior applications of torque in any variation of any prior art to rotate the hub.    What is claimed is a way side rail tool with a suspended horizontal beam above the ground with sufficient height to provide clearance for a technician to approach the rail car with out having to climb over or crawl under said horizontal beam.    What is claimed is a operator station  109  but not limited to a open air station as a climate controlled station is preferred to limit the operators exposure to airborne particles emitted during the unloading process and attached to the traversing members with controls for operation of said opener and closed members as depicted in this application so that the operator is in a safe environment and moves with the opener/closer members to provide a closest proximity of visual observation and operation of the process of opening and or closing said rail car doors of a hopper car with doors disposed on the bottom of said rail car.
