Description

1879.

CARL KEERL in NUREMBERG. M a I ζ s c h r ο t m ii h I e with automatic measuring apparatus.

Patented in the German Empire on July 20, 1879.

The machine consists mainly of:

1. from a roll stand;

2. from the equipment box;

3. from the basin;

4. from the multi-part mechanism which serves to move the Mefs-vessel.

The roll stand a, made of cast iron, is used to hold the two crushing rolls b and c made of hard cast iron and rotating in brass bearings. The latter are grooved and have a% trail; the smaller of the rollers b is driven by means of belts and the larger c is carried along in the opposite direction by the malt squeezing between the rollers. This arrangement causes the machine to run extremely smoothly, it works almost noiselessly and a very beautiful malt that is extremely suitable for boiling is achieved. Two weight levers d, which have the purpose of constantly pressing the larger of the rollers against the smaller, complete the roller stand. The container e of the Mefsapparates is screwed onto this latter; on the left outer side of the container there is a spur gear /, which is driven by a smaller spur gear g , which is keyed onto the end of the shaft of the small crushing roller. The spur gear / is the drive of the conveyor roller h and also serves, since a small belt roller i is keyed on one side of the conveyor roller axle, to move the Mefsgefäfses k. A weighted lever /, which is located between the drive wheel of the conveyor roller and the container e, is used to regulate the inlet flap m and it is possible through the regulating screw n, which presses on a protruding shoulder of the lever /, any more or to let less malt run on the crushing rollers. The weight lever / enables at the same time, that gröfsere foreign body (eg. As stones, which are located under the malt) the Zulafsklappe m can pass through without That the machine alterirt therethrough and is teschädigt. On the right side of the apparatus, above the already mentioned small roller i, there is a larger such roller 0, which is connected to the former by a belt. On the axis of the roller 0 going through the container e (on the inner surface of the left container wall) a small spur gear p ^{l is} keyed, which meshes with a second wheel ( ^s) ; this wheel J> ^u is mounted in a fork rod q , which is attached to the upper flap r in the container e so that it can move in the hinge. The wheel ( ^s) comes into contact with a third wheel p ^m , the latter being attached to a stand t attached to the lower flap s. Finally, a fourth wheel / ^IV , which turns on a pin fastened inside the left wall of the container, completes the gear mechanism for moving the Mefsgefäfseses. The Mefsgefafs k itself is an oval-shaped cavity that is open at the top and bottom. The same can be rotated about an axis u mounted in the container walls and coupled to the wheel / ^IV with a connecting rod υ. An adjustable disc w, which can be screwed in or out on the left side of the Mefsgefäfses, which is fixed with a lock nut, is used to adjust the cavity and a radius corresponding to the radius ' χ on one side of the Mefsgefäfses to close the upper filling hole during emptying of the Mefsgefäfses. While the measuring vessel is being filled, the lower opening of the same is closed by the plate y , the front end of which extends the measuring vessel during emptying in such a way that the lower opening of the same becomes free and emptying can take place. The upper flap r located in the container e as well as the lower flap s are balanced with a weight lever z ¹¹ and z ^l so that they always strive to go up. The apparatus now functions in the following way: By loading the upper flap r with heaped malt, this flap will assume a lowered position and, as a result, the wheel p ¹¹ , which until then was a little higher, will be placed between the wheels / ¹ and p ^m . The wheel p ^m then simultaneously establishes the connection with the wheel / ^IV by being pushed upwards by the lower flap s with its weight lever z ^l. The Mefsgefafs k with the upper opening at the filling hole is then through the

penetrate the malt filled. The apparatus is set in motion and now the wheels ^ ^1/11/111 / ^ the Mefsgefäfs is forced through the mesh, to rotate about its axis and to make such a movement, that the tab-like Angufs χ verschliefst the fill hole, the lower opening of the Mefsgefäfses is released and the contents of the latter on the lower flap emptied s. This now lowers and, by pulling the wheel p ^m downwards, releases the connection of the wheels / ¹¹ and / ^IV until it can rise again as the malt runs off. The measuring vessel k remains in the empty state for so long; it first fills up again, and indeed very quickly, by making the movement back, whereupon it is immediately able to empty itself again. Under these circumstances, the malt cannot be shaken in or solidified. The machine functions in the manner described as long as the malt lies on the upper flap r. Only when this has expired can the upper flap go up and, by pulling the wheel p ¹¹ up with it, break the connection with the other wheels. The measuring vessel now stands still, although the other parts of the machine are still in motion. A counter z ^m produced in a known manner , which is connected to the Mefsgefäfsaxe, registers when the vessel is in function, the filling resp. Emptying of the same. The inventor reserves the right to replace the wheels ρ ^Ι ρ ^η ρ ^ιιι ρ ^{ϊγ with friction disks.} The plate y is attached to the two container walls.
