Addendum to patent 284747.

Patented in the German Empire on October 21, 1915. Longest duration: May 27, 1929.

The invention relates to a pan mill with driven plate and rotor which according to patent 284747 the central emptying opening of the plate by a axially displaceable piston is closed. Will the discharge chute as in the main patent fixed in an inclined position, the inconvenience arises that when retracting of the sealing piston from the emptying opening of the plate into the discharge chute the upper surface of the piston is not flush with the surface of the inclined bottom of the discharge chute, especially when the plate is driven around a vertical axis. The wedge-shaped part of the locking piston, which then protrudes into the discharge chute prevents the ground material from flowing out the slide.

To remedy this bad situation, is after of the invention, the discharge chute encompassing the sealing piston by a horizontal one Axis rotatably arranged in such a way that it is parallel or almost parallel in the closed state is parallel to the surface of the locking piston, and after the latter is withdrawn so far that its surface is flush with the surface of the bottom of the discharge chute, the latter together with the piston encompassed by it at a desired angle of inclination can be brought.

The subject of the invention is shown in the drawing, for example, with a pan mill bowl-shaped plate shown; namely Fig. I is a vertical section through the new one Device, while Fig. 2 shows a detail.

α is the driven bowl-shaped plate of the pan gear, the central emptying opening c of which is closed by the axially displaceable piston b.

The discharge chute d is usually, ie during the operation of the pan mill, horizontally under the discharge opening c of the plate α and has an opening e corresponding to the piston b in the bottom.

The slide d is firmly connected to two bracket-like supports h and can be rotated together with them about a pin /. On the side of the pin I opposite the slide d , the console h carries a counterweight i. The console h carry a pivot k for a lever 0, which is rotatably connected to the rod / the locking piston b at g. On the side of the pivot k opposite the locking piston b , the lever 0 carries a guide roller η for which a fixed guide track m is provided.

The new facility works as follows:

During the pan mill operation, the parts are in that shown in FIG Location.

If the plate α is to be emptied, the handle of the lever 0 is pulled upwards. Here, the one carried by the lever 0 moves first. Role η along the almost perpendicular

Claims (3)

Part of the guideway in, so that the locking piston b executes an axial movement and enters the opening e of the bottom of the discharge chute d. While the sealing piston b has been withdrawn so far that its surface is flush with the surface of the bottom of the chute d, the guide roller η has reached the end of the vertical part of the guide track m. During the further ίο upward movement of the lever ο the slide d then swings around the pin /, the roller η moving around the pin I on the circular cylindrical guide track m. If the emptying opening of the plate a is to be closed again, the downward movement of the lever 0 first brings the slide together with the locking piston b carried by it into the horizontal position and further depressing the lever 0 as a result of the movement of the guide roller η along the vertical Part of the guide track m of the locking piston axially shifted from the opening e of the chute d into the opening c of the plate α. In the illustrated Ausführungsforni the weight of the discharge chute can be chosen so that, after the roller η leaves the vertical guide track, the slide swings out automatically around the pin I and takes the lever 0 with it, while the roller η on the circular path m around the Pin I moved. In the embodiment shown, one and the same lever 0 is used for the rotational movement of the slide and the axial displacement of the locking piston. Of course, an arrangement can also be made such that two separate levers are used for the axial movement of the locking piston and for the rotational movement of the slide . Pat τ claims: 1. pan mill with driven plate and rotor according to patent 284747, characterized in that the sealing piston (δ) comprehensive discharge chute (d) together with the axially from the discharge opening (c) of the plate (a) retracted sealing piston (b) by a horizontal Axis (ΐ) can be rotated. 2. pan mill according to claim I, characterized in that the about the horizontal pin (I) rotatable slide (d) on brackets (h) the pivot pin (k) for a lever (0), which is guided in such a way that when it moves, initially only an axial displacement of the locking piston (b) and only after the opening (e) in the chute (d) is closed by the locking piston (b) does the chute swing out can be done with the piston. 3. pan mill according to claim I and 2, characterized in that the <inevitable movement of the piston (b) and the chute (d) by a lever (0) carried guide roller (η) and a correspondingly shaped guide track provided for it ( m) is effected.
