Improvements to the patent no. 2325 machine protected by Nagel & Kaemp, in order to reduce the amount of material to be crushed by means of striker disks when there is no air supply.

Patented in the German Empire on July 24, 1879.

Proceeding from the view that it is the air which, acting as a cushion, causes this Can't grind finely with the older centrifugal mills, Inventor has a grinder constructed in which this condition, as well as the danger of inflammation, is entirely eliminated.

In the accompanying drawing, Fig. 1 is a section through the axis of the machine and Fig. 2 is a cross section through the lower part along the line xz of Fig. 1.

The actual housing of the machine has neither a cover nor a base, but is in unimpeded connection with the flour container and, during work, with the bulk trunk, so that the three parts: housing Έ, flour container K and grist container G form a single cavity , which is hermetically sealed to the outside.

The shaft A with the belt pulley B carries the rotating pin pulley C at the top, while the other pin pulley D is fixed to the housing.

The ground material is given through the opening F, which is closed with the easily openable lid /, into the body G , from where it passes the slide g into the telescopic tube Hh , the removal of which from the rotating pin disc C from the outside, with assistance of the wheel J, can be adjusted. The ground material exiting through H flies between the rows of pegs, is crushed and the flour fills the space K , the size of which is dimensioned so that it can hold as much flour as the body (9 can hold the ground material.

The lid L, at the lowest point of K, can easily be removed to empty K.

So that when an air pump sucks out of the pipe M , the whole interior becomes evacuated evenly, the space above the ground material is connected to the space below the ground material through the pipe N.

In order to avoid a stuffing box at the rapidly revolving shaft A, the inventor has applied to it patentirtenrotirenden already for other purposes Wasserverschlufs, which is formed by the surrounding on Mahlbehälterbefestigte, the shaft A pipe O DAF with its Flantsch 0 from a fixed to the Riemscheibe Water or another liquid-containing round vessel P is enclosed. The rotating water, by virtue of its inherent centrifugal force, opposes the necessary resistance to the atmosphere. The rooms G, E and K are accessible through handholes R and windows Q.

When starting work it is necessary to go ahead Effect of the air pump on the water seal. to set in rotation .. The drawn mill, is intended for the grinding of small quantities, expensive colors, whereby it is not regarded as an inconvenience that the machine is able to. The purpose of emptying and filling must be stopped each time.

If one wants to avoid these interruptions, one does not fill G through manhole F, but; through the dotted tap .S from an evacuated container located above, and empties K not through the manhole L, but through the dotted tap F into an evacuated container located below. Flour jar ..

Claims (1)

Patent claim: A striker machine, which is characterized by the airtight closure of the bulk trunk G and flour container K, by the. Taps S and T on the body G and container K " through the air communication pipe N and the water connection as a replacement for the stuffing box for the corrugation. 1 sheet of drawings.
