Railroad dump car with side shovels.

Addendum to patent 222355 of October 18, 1908.

Patented in the German Empire on November 28, 1908. Longest duration: October 17, 1923.

The invention relates to a further embodiment of that described in patent 222355 Railway dump truck with automatic excavator and serves the same Purpose, the dump truck equipped with such a device during to be automatically filled with dredged material during the journey.

It differs from the subject matter of the main patent by a different type of Suspension and drive of the shovel arm and the shovel.

In the drawing, the invention is shown in one embodiment.

Fig. Ι is the front view of a car,
Fig. 2 shows the side view.

FIG. 3 is a front view corresponding to FIG. 1 with the excavator device in a different position.

Fig. 4 is a side view,
ao Figs. 5 and 6 are sections of a coupling device.

α is the underframe of a railroad car, which carries the tiltably mounted car body b intended to receive the dredged material. The underframe α rests on two pairs of wheels c and d with the wheel axles c ¹ and d ¹ . Can be on the wheel axle d ¹ d ² is a sprocket (FIG. 2) is mounted, which (not shown) by a suitable Kupphängevorrichtung with the axis d ¹ coupled. On the base α , two chain guide wheels e are rotatably mounted in front of the axis d ¹ , the axes of which are inclined. Furthermore, a shaft f is mounted on the underframe α parallel to the longitudinal direction of the carriage and carries a crank g at both ends and a chain wheel h above the guide wheels e. An endless chain i is laid over the chain wheel d ² , the guide wheels e and the chain wheel h . If the chain wheel d ² is coupled to the axis ^{d 1} and the carriage is pushed in one direction or the other on its track, the shaft f is set in rotation by the chain i.

At the front and rear ends of the subframe α , a frame k bent from angle iron is attached to the subframe itself.

A swing frame q, which carries one or more shovels r at the outer end, is suspended and connected to the cranks g in such a way that when they are rotated, the shovel r is lowered onto the soil to be dredged and then inevitably lifted above the car body b and emptied will.

The oscillating frame q is driven in the following manner: A shaft parallel to the shaft f / or two pins I in the same direction is mounted on the frame k. Around the corrugation (or the tenons I) between the car body and the frame k each a winch

Claims (4)

rocker arm m ¹ m ² swing. At the outer ends of the longer arms m ¹ is the swing frame q by means of the end pins of the shaft ¹ q articulated. The crank pins of the cranks g engage in slots of the shorter arms m ^{2 of} the angle levers m ¹ m ² . When the shaft f rotates, the angle levers ^{mim 2} and, accordingly, the shaft q ¹ receive a reciprocating movement. The extreme ίο right position of the shaft q ¹ can be seen from FIG. i, the extreme left position from FIG. The location of the swing frame is q apart from the position of the shaft q ^1, which is moved forcibly in the manner just described, also depending on the location of the mounted at the rear end of the oscillating frame pin q ^2, q during the oscillating movement of the frame for a time inevitably be moved. At the tap ao fen q ² rods η are articulated, the lower ends of which are guided by bearings 0. While . the oscillating movement of the rods η from the position shown in Fig. 3 to the in Fig. Ι dotted position, the rods η can only rotate in their bearings 0 , but not move. The swing frame q carrying the blades r is displaced parallel to itself during this movement, namely essentially horizontally. In order to finally bring the blades r down to the ground, a device is made so that the rods η can move in their bearings 0 from the moment they have reached the position shown in dotted lines in FIG. Up to this point, the shift is prevented by a lock. Each rod η is guided through a pin head o ² which is rotatably mounted in its bearing 0 with the pin o ^1. A horizontally displaceable bolt o ³ (FIGS. 4 and 5) in the bearing 0 engages in a recess n ^{1 in} the rod η and prevents the rod η from moving upward in the pin head. A spring o ⁴ keeps the bolt o ^z constantly in the engaged position. If the rods η swing from the position shown in FIG. 3 to the right, the latches o ^{3 are} gradually pushed to the left against the action of the spring o ⁴ , by the action of the lower rod ends on the pawls o hinged ^{to the latches o 3 B.} In the position of the rods η shown in dotted lines in FIG. 1, the pawls o ^{B are} displaced just enough to the left that the locking is just canceled. The pins q ^{2 of} the swing frame q are no longer held by the rods η from this moment on; the blade r falls so far down until the blade or to connected with the blade (not shown) wheels, which regulate the cutting thickness of the blade, the push open on 'to be dredged soil. Here, the pins q ² swing upwards to the position shown in FIG. 1, the rods η being displaced in the pin heads o ² . In this position shown in Fig. Ι the shovel r is in engagement with the ground and takes on dredged material during the displacement of the wagon. With the further rotation of the crank arm g , the arms m ^{1 are} rotated to the left. The shovel r is also shifted somewhat to the left during this movement, but initially still remains in engagement with the ground, so that during the movement of the carriage in the ground it shovels a slightly oblique or curvilinear strip to the rails. Supports m ^{3 are} attached to the arms m ^1. If the arms m ¹ are now rotated to the left from the position shown in FIG. 1, after a certain angle of rotation the oscillating frame q is supported by the supports m ^s , and when the arms m ^{1 are} further rotated to the left, the blade r lifted off the ground. The pins q ² then also describe a circular movement around the shaft I. At the end of this movement, the rods η are pushed down again through the pin heads o ^2. When the position shown in FIG. 3 is reached, the bolts o ³ snap into the milled recesses M ¹ again. Almost in the end position, the swing frame q is in an approximately horizontal position above the car body b. During the further shift to the left, the shovel r, the pins r ^{1 of} which perform a circular movement around the pin I , with projections attached to the side of the shovel, hits against arms k ¹ riveted to the frame k and is forced by them to wrap around their pins r ¹ and pour its contents into the car body b . As the cranks g are rotated further, the oscillating frame q is shifted to the right again, specifically up to the position shown in dotted lines in FIG. In this position, the bolts o ³ , which had retained the rods η in the pin heads o ² , are released. The swing frame q and the bucket r sink down to the ground and the excavation begins again.
