11 Claims.

5 loaded. One form of such apparatus embodies a car dumper, having a pan or other member into which the oarcontents are adapted to be emptied, and from which a discharge chute extends down- Wardly into the load receiving vessel. One form 10 of chute, which has been used for this purpose has embodied a plurality of intertting telescopio tubular members, which collectively are arranged g to be inoved universally with reference to the at 13, while a discharge chute 14 is shown as extending downwardly from the lower end of the pan. The chute 14 is mounted for universal movement with reference to the pan; movement in one plane occurring about the axis of the hinge pin 15 and in a transverse plane about the axis of the hinge pin 16. lThe mechanism for eiiecting such movement does not form part of this invention and therefore, it is not shown in the drawings.

The present invention is concerned with the provision of means for shifting the discharge chute in a direction tnvmrd mm 9mm, fsm +1 which is suitably connected by gearing 41 to a drum shaft 42. I then provide two drums 43 on the shaft and utilize cables 44, which extend from the drums', and are connected at the ends thereof to the carriage. Thus, when the motor is operated to wind in the cables, the carriage is pulled upwardly and the conduit 20 is contracted. With this arrangement, I may utilize a motor brake, which if reelased, will allow the carriage to drop by gravity. During such upward and downward movement of the carriage, the discharge chute may be moved parallel to itself without shifting the position of the pan about its pivot 45.

In Figs. 3 and 4, I utilize a reversible motor and I so connect the ends of each cable to the carriage that rotation of the motor in one direction will pull the carriage upwardly, while rotation in the opposite direction will force the carriage downwardly. To carry out such plan, the parts-corresponding to those illustrated in Figs. 1 and 2 are identified by the same reference characters, so that only the modified mechanism need be described. Such mechanism comprises sheaves 46, which are mounted for rotation upon the supporting

members

29 and 30 and below the extreme limit of downward travel of the rollers 35. The cable is then wound around the drum a sufficient number of times to avoid slippage, while-the drum is being rotated, and one end l4'1 of each cable is attached to the carriage at 48,`

while the opposite end 49 after passing around the associated sheave 46, is also attached'to the carriage at'48. Thus it is apparent that rotation of the motor in a direction to pull upwardly on the cable end 47 will draw the carriage upwardly while rotation in the opposite direction will place the cable 49 under tension, and thereby draw the carriage downwardly.

A further modification of my invention is illustrated in Figs. 5 and 6 wherethe mechanism for actuating the carriage embodies a rack and pinion connection. Here again, the parts corresponding to those illustrations in Figs. 1 and 2 will be correspondingly numbered so that only the modified mechanism need be described. Such mechanism comprises pinions 50, which are adapted to engage racks 51 on the underside of the carriage. The pinions in turn are mounted for rotation upon the relatively stationary members 27 and are disposed below the extreme limit of downward travel of the rollers 35. Thus, rotation of the motor in one direction will shift the carriage in one direction, and vice versa.

An important advantage Jf tl .e present invention is the fact that regardless of the width of the vessel that is to be loaded, the chute discharge opening may be positioned in close proximity to either side of the hull without necessitating an objectionable drop of the material from the chute into the vessel.v Thus, I minimize breakage and assure accurate distribution of the load without necessitating, unnecessary manipulation of the pan. Furthermore, anrapparatus embodying my invention may be readily installed on existing car dumpers without necessitating extensive modifications in the construction thereof.

I claim:A

1. In a car dumper, the combination with a material receiving pan, of a member supported by the pan and movable longitudinally thereof, a discharge chute vpivotally connected to said member, a closed extensible connection between the lower end of the pan and the upper end of the chute for providing communication between the pan and chute, and an electric motor operatively connected to said member for moving it with reference to the pan, whereby the chute may be moved, as a unit, with reference to the pan, while remaining in operative communication therewith.

2. In a car dumper, the combination with a material receiving member, of a discharge chute extensibly connected to said member, a carriage mounted on the member, and pivotally connected to thechute, means including a closed telescopic conduit for connecting the chute and member, and means for shifting the carriage with reference to the member, whereby the chute may be moved toward and away from the pan, while the axis of the chute is maintained in substantially the same position with reference to a vertical.

3. In a car dumper, the combination with a material receiving member, of a discharge chute extending downwardly therefrom, said chute being extensibly connected by a closed conduit to the member, a carriage mounted on the member, a cable connected to the carriage and means for moving the cable to raise or lower the carriage, whereby the chute may be moved with reference to said member, while the axis thereof remains in substantially the same position with reference to a vertical.

4. In a car dumper, the combination with a supporting frame, of a discharge pan mounted thereon, a carriage supported by the pan, a closed discharge chute connected to the carriage, means for moving the carriage and chute with reference to the pan, and means forming a continuous passageway between said pan and chute in all operative positions.

5. In a car dumper, the combination with a material receiving pan, a closed articulated passageway in communication with the lower end of the pan, and means supported by the pan and movably mounted with reference thereto, said means being connected to the passageway intermediate the pan and the discharge end of the passageway, and means for shifting the pan-supported means with reference to the pan whereby the passageway may be extended and contracted in a direction extending longitudinally of the pan.

6. In a car dumper, the combination with a support, of a pan pivoted thereto, a material'conducting conduity operatively connected to said pan, said conduit being closed and extensible, and extending in a direction longitudinally of the pan,

and a carriage shiftably mounted externally of thepan and operatively connected to the conduit for extending and contracting it with reference to the pan.

7. In a car dumper the combination with a material receiving pan, of an extensible material conducting conduit connected therewith, a discharge chute depending from said extensible conduit, an electric motor mounted on said pan and mechanism includinga rack and pinion for connecting the motor to said chute, whereby rotation of the motor in either direction moves the chute toward and away from the pan.

3. In a car dumper, the combination with a pan, of a closed articulated passageway connected with the pan and extensible in two directions from a common point on the passageway, a pivotal support forthe common point, and means for moving the pivotal support toward and away from the pan.

9. In a car dumper, the combination with a material receiving pan, of an extensible conduit in a common plane with the pan, said conduit tinuation thereof, and a discharge chute pivotally` connected to the hollow member, the extensible conduit cooperating with the elbow, hollow member and chute to provide a closed articulated and continuous conduit.

11. In a car dumper, the combination of a material receiving pan, an extensible conduit at the lower end of the pan, a carriage supported for movement in a line parallel with the conduit, an articulated elbow at the lower end of the conduit, said elbow being pivotally supported on the carriage, and a discharge chute pivotally supported on the elbow, said last-named pivot extending in a direction normal to the first-name pivot.
