HYDRAULIC UNLOADER.

Application ledAugust 15,y 1921. Slerial No. 492,454.

To all lwhom t may concern:

Be it known that I, KARL FLscHE, residing at Halle-on-the Saale, Germany, have invented certain new and useful Improvements in Hydraulic Unloaders (for which German Patent No. 289,124, dated February, 20, 1914, has been granted and for which application' for patent in Germany has been filed July 21, 1914), of which the following in a specification.

This invention relates in general to a device for unloading loose material intbulk from railway cars by means of a water jet. It relates more particularly to a device of the kind that enables the nozzle from which the water is ejected, and which must be arranged to be moved relatively to the cars in a vertical and a horizontal direction, to be moved in such a manner that in all places intol which the nozzle is shifted the most favorable effect of the water jet on the material to be discharged is obtained. In accordance with my invention all themotions executed by the nozzle are imparted to it from an operators positionin such a way that the inclination of the water jet to the horizontal always remains the samefin all places Ainto which the nozzle is brought.

A constructional form of the invention is shown in the drawing. f

Fig. 1 is a side elevation of my novel device, partly in vertical section,

Fig. 2 is a correspondingv plan view, and

Fig. 3 is a sectional plan view of Fig. 1 on the line 3 3.

In the form illustrated my invention is adapted more particularly `.for unloading sugar beet from railway cars in sugar mills. The sugar beet are brought in open trucks 1, 1 shown diagrammatically in the drawing, to the sugar mill. The rails at the sugar mill are situated adjacent to a trough or flume 2 and the cars are rolled into positions beneath the unloading device, which is similar in appearance to a revolving,

crane. The portion of the device that acts on the material to be unloaded consists of a nozzle 3 capable of being moved in the space above the vcar and'through which a powerful jet 4of water may be spurted. The nozzle receives water under pressure which is preferably supplied from a centrifugal pump 4 in the interior of a tower-like structure 5. The suction vpipe 6 takes 'in water from any suitable supply (not shown) pipe 10 is closed 4at one end and has a stuff.

ing box 11 at its other end throughwhich a Y horizontal telescopic tube 12 may be slipped in and out. The outer end of the tube 12 is connected by means of a flange 13 to a vertical tube 14. i

From the vertical tube 14 the water under pressure passes through slots 15 into a vertical pipe 16 to the lower end of which the nozzle 3 is fixed. The innerpipe 16 and the externalk pipe 14 have a common' axis `and the inner pipe 16 can be turned about the said axis and moved in the pipe 14 in telescope fashion in the direction longitudinally of the said axis. The pipes'9, 10, 12, 14, 16 with the nozzle 3 and all the devices for shifting the pipes rest upon a frame which is preferably madeof two ironfgirders 17, 17 which extend 4parallel to the pipes-10, 12 and are joined to each in any suitable manner-by cross-ties. The frameis borne by rolls 18 adapted to 'travel round on a Acircular rail `19 mounted' on the tower' 5.

20 is an electromotor for turning the frame 17, and all the parts fixed to it, about the axis of the tower. Through any suitable gear, such as a "worm and lworml wheel enclosed in a casing 21 and bevel wheels 22, the motor 20 drives a pinion 23v which is in mesh with a circle of teeth 24 fixed on the tower 5. When the motor 'is started the vframe 17 and all the parts fixed to it including the nozzle 3 are rotated around the axis of the tower.' I

The operators cage 25 is also'mounted on the frame 17 so that it is also carried round with it. Switching devices for the electromotor that operate the frameJ 17 and the various movable parts are arranged at the operators position in the well known man'- ner adopted in cranes. A stop valve 26, by which the operator can regulate. the flow`of water to the nozzle 3, can also be worked from the operators position. y

The outer end of the pipev 12 together with the tube 14 and the devices associated therewith rests upon a small truck 27 arr-angled,-

like a crane traveller and adapted totravel on rails 28,- 28. The truck `27 is driven by an electromotor 29 which, Vby suitable inter-l mediate gear, rotates two spur wheels 30, 3() that engagev with

racks

31, 31. As has been already mentioned thefelectromotor 29 is controlled by devices arranged at the operators position By causing the truck 27 to travel along the rails 28 the pipe 12 is pushed into the pipe or pulled out of it.

The tube 16 that carries the ynozzle 3 is cut olf from communication with the pipe 14 by a stuffing box 32 in which the tube 16 can slide and rotate. At its upper end the tube 1G has an extension 33 which passes through a stuffing box 84 at the top end of the pipe 14. By this means the tube 16 is securely guided in thc pipe 14. Mounted 'at the top of the rod S3 is a cross-piece 35 and another-cross-piecc is lined to the lower end of the tube 16. These cross-pieces are interconnected by four rods one pair B7, 37 of which is smooth while the

other pair

38, 38 have screw threads at their upper ends and are provided with nuts 39 at their upper ends. The nuts 39, whose vertical position relative to the frame 17 is fixed, are shaped at their peripheries in the form of worm wheels which engage with

worms

40, 40 that can be rotated through speedchanging gear by the electroinotor 41. The motor is also controlled from the operators position 25. 'Vhen it is started the tube 16 is pushed into or pulled out of the pipe 14 and the height of the nozzle 3 above the car 1 is thus decreased or increased according to the direction of rotation of the said motor 41. The tube 16 in the pipe 14 is rotated by a small electromotor 42 and carries the nozzle 3 around with it. The electromotor 42 may be arranged to act through the medium of gear wheels on a worm 43 which engages with the worm wheel 44 keyed to the lower end of the pipe 16. The motor 42 is also controlled from the operators stand 25.

The motions of the nozzle 3 driven by the electromotors 20, 29, 41 and 42 may take place one at. a time or all together without mutually interfering. It will be, obvious that during all of these motions of the nozzle 3 (which are imparted to it for the purpose of bringing it into the proper position relatively t-o the material to be unloaded from the car 1) the angle which the jet issuing from the ynozzle 3 forms with the horizontal is never changed. By this means it is possible to maintain the most favorable eliect of the jet in all positions of the nozzle.

The Inode of operation of my novel device is as follows:

The loaded car 1 may be moved to the place where they are to be unloaded by any known means. In the. example shown in Fig. 2 it is assume-d that a shunting windlass 45 is provided for this purpose. This windlass drives an endless rope 46 to which the car may be temporarily hitched by any suitable kind of gripping device or the like. As this kind of rope driving plant is well known a more detailed description of the same is unnecessary.

l/Vhen a car has beenl hauled into position beneath the frame 17, 17"r it is unhitched and the side doors l of the truck are opened. Then the nozzle 3 is moved into the proper position by means of the motors controlled by switching devices at the operators position and, the pump 4 having beenY started, a powerful water jet is directed against the sugar beet (or the like) near the opcndoor. The sugar beet will then slip out of the car and will be thrown bythe water into the channel or launder 2 and transported by the impelling water to the places where'they are needed. As the unloading opera-tion proceeds the operator at his stand 25 shiftsthe nozzle 3.

Since, in all positions into which the noz zle is shifted, the inclinationk of the water jet is maintained at the angle which has been found by experience to be the most favorable for the kind of material dealt with, the work of unloading will be considerably expedited. y

Vhen a car is completely unloaded the pump is stopped and a new car is hauled into position by means of the windlass 45' and the e rope 46.
