standing liquid for metering) he receives; he is on connected to a fixed supply line in the pigsty, cattle shed or other structure, which is supplied with the aid of the device according to the invention with the hose being wound on a rotatable drum 10 carried by the carriage 7 will. The supply of the container is effected via the core of the drum 10, one end of which with a swivel joint is provided that allows the exit of the liquid via a radial line 12 that it in the Inside of the container 4 conducts.

The rotatable drum 10 is proportionally rotatable with one of the wheels 14, preferably a driving wheel, and is driven by the carriage 7 through the intermediary of a belt 15 and a friction clutch 16.

The container 4- is equipped with a valve 13 with adjustable Provided outlet which opens into the mixing chamber 6. The more or less large bze. strong opening of the valve during a certain time, which corresponds to the time of the delivery of flour, it allows the proportion of in the mixing chamber to change the introduced liquid.

The above-mentioned valve 13 is by interposing a

surrounded by a sheath, sheathed cable 23 connected to a device & to adjust its opening. These The device shown in Fig. 3 is mainly composed of two mutually rotatable flaps or Wings 18 and 19 together, in such a way that they form a V lying on its side, its horizontal axis of rotation with one of the physical supports 7a of the carriage 7 is firmly connected.

Transmits each of these flaps or wings a the other opposite lever or arm 20, 22 to äsr other side of the aforesaid rotation axis with respect to the flaps 18 and 19 is arranged, wherein the free outer end of the one lever with the cable 23 connected , while the outer free end of the other lever of the sheathing of the rope serves as a support or support. The other end of the rope 23 is connected to the closure member or the flap 13 a of the valve 13.

This device works in cooperation with a fixed fork 24, which serves for measuring or dosing and is arranged at the adjacent end of each feed trough 11. Preferably, and as shown in Fig. 4, this fork 24 is from the upper part of a railing 25 or a barrier worn _{s one or the other}

This fork is fixed at a certain point, but can be in the longitudinal direction can be moved and the spacing of the arms or tines it contains can also be changed will. These arms are oriented in such a way that the tip of the V formed by the wings 18 and 19 is formed carried by the carriage 7 is engaged between them.

In this way, the flaps or wings are forced between the aisle when the car moves Legs or prongs of the fork 24 to go through what inevitably their compression and removal the lever 20 and 22 causes one another. As a result, a train is exerted on the rope or cable 23 and causes an adjustment of the closure member 13a of the valve 13 in the sense of its opening, the amount this adjustment is proportional to the amount of compression · of the wings 18 and 19. In these Conditions it is understandable that it is sufficient to change the distance between the arms ^ of the prongs of the fork 24, by the amount by which the aforementioned flap 13a is opened and consequently the delivery rate of the outlet slide

to change.

The time for the flour to flow out is the same as the time for the liquid to flow out, so it is understandable that the one poured into each! Amount of wet mixture, as well as the amount of flour, also a function of time to drain of the liquid will be o A system that allows the valve 13 to be in the open position, which is given to it by the Fork 24 has been granted to hold is connected to this device and assigned to this device. This system mainly consists of a toothed rack 27 which, at one of its outer ends, is connected to the lever 20 is rotatably connected. The toothing of this rack is in position with a firmly attached to the lever 22 Fingers working together, these teeth being oriented in such a way that they are removing the two Lever 20 and 22 allowed from each other, but that. Closing this lever prevents. A spring 28 ensures that the teeth are in contact with that of the lever worn finger remains.

This rack 2? also works with one at the top Part of the railing 25 attached stop 29 together. This stop is in the path of the lower one

! Part of the rack 27 in such a way that it turns the rack to the Side pushes or pivots, which then the finger carried by the lever 22 and, as a result, the two levers 20 and 22 releases, the Bich then close again and thereby cause the valve 13 to close, wherein In addition, Hittel are provided in order to bring about the stopping of the dosing device 3 when adjusting the rack,

It is therefore understandable that the time during which the liquid and flour flow out is a function of the distance between the fork 24, which causes the valve 13 to open and the metering device to operate, and the stop 29 which closes it the valve and the stopping of the Dosfergerätes ensures the stop 29 and is lockable course, adjustable in the longitudinal direction along the railing at any iHinkt of the railing.

If one attaches a fork and a stop 29 to the right of the spring feed trough 11, one can determine or ensure with accuracy the delivery quantity and the delivery speed of the liquid and / or of the hehl which flows off in the chute 6a *

In this way, if you dispense the floury! Feed and the liquid into the chamber 6 at the same time, a mixture called "soup ¹¹ " can be distributed into the feed troughs 11, the dosage of which can be determined with accuracy by monitoring the dispensing of Water varies in the manner described above

For the event in which it is desired to make the distribution of the feed independent of the displacement of the wagon 7, and in particular in the event that feed troughs arranged at right angles to the aisle 26 have to be borrowed, a temporization is used - Or timing device is provided which allows the amount of liquid and flour introduced into each of the feed troughs to be metered, the carriage being stopped at the location of the feed trough The device comprises a set of elements and components similar to that which also contains the device for regulating the flow of liquid, i.e.. it consists of two wings or flaps 50 and 32 which can be twisted against each other and are each provided with a lever 33 and y ±

The free outer end of one of these levers is with the Saide

■ - 19 -109845/1140

a cable or rope 35 connected and the outer free end of the other lever is used for support

and holding the sheath of this cable 35 »The device is carried by the carriage 7 through the intermediary of the axis of rotation the wing 30, 32 · The other end of the rope or cable 35 is connected to the rod of a piston 36. This piston 36 is provided with a valve 37, which has a calibrated hole 38, and it can be located inside a tight, oil-filled Move cylinder.

This device is intended to be used with a fork 40. Which, like the fork 24, is carried by the upper element of the railing 25, and in is attached to this in such a way that the compression of the wings or flaps 30 and 32 is ensured or is guaranteed if the lower end of the chute 6oan the one that is transverse to it the feed trough has arrived Set the -4O fork arms to the desired value and adjusted so that the wings 30 and 32 are proportionally compressed and a corresponding displacement of the piston 36 in the direction of arrow 42 of FIG. is performed. It can be seen that the amount of this

- 20 109845 / 11AO

Displacement determines the time set by piston 36, to return to its original or resting position.

This temporization or time control device is necessarily assigned a limit switch 4-3, which the Controls and controls the emptying time of flour and liquid. This limit switch ^ controls and actually controls the supply of the drive motor of the metering device 3 and that of an electromagnet 29a, which replaces the stop 29 by being carried by the carriage 7 to act on the rack 27 can.

As a result, one can, by looking appropriately attach a fork 4-0 to the places corresponding to a transverse feeding trough, in which the distance the arms or tines are regulated in a suitable manner, as in the case of the feed alley or walkway 26 feed troughs arranged in parallel with each of these transverse feed troughs an individual supply to ensure.

It goes without saying that suitable means must be provided in order to
