Description

IMPERIAL

PATENT OFFICE.

The present grist sifting machine is intended to achieve as complete a separation as possible between Peel, flour, good semolina and steam.

The machine is shown in Fig. 1 in longitudinal section, Fig. 2 in side view, Fig. 3 in outline from above and in Fig. 4 half in cross section according to AB and the other half according to CD of FIG.

In the housing formed by four posts M and the same laterally clad wooden wall N , two bearings b and h are attached, in which a hollow shaft E with a pin / and a shaft d coupled to the hollow shaft E through a perforated cover plate % and a bolt k , which is driven by a pulley η , rotates. .

The bearing shells g and i of the bearings h and b are divided and adjustable.

The housing is divided into three separate spaces AB and C by plates 00 ¹ O ² and O ^3. A fifth closing plate riveted under the lowest closing plate o ³ forms a fourth closed space D. Conical drums cc ¹ and c ² with inclined working blades / Z ¹ and Z ^{2 are} screwed onto the shaft d and the hollow shaft e; these are enclosed by likewise conical sieves mm ¹ and m ² , which are stretched in rooms AB and C over screwed-in wooden rods.

This results in three separate rooms in rooms AB and C , which are to be referred to as the actual work rooms, as the work wings circle in them.

The feed funnel a opens into the upper cover plate 0.

The machine works in the following way:

The coarse meal, as it comes from the millstone, is introduced into the feed hopper α and falls into space A, where it is thrown by the wings / against the sieve m; the shells collect below the vane drum c and fall through the cutouts of the clutch disc \ and through the interior E of the hollow shaft e into the discharge tube H, while flour and fine meal collect in space A and fall to the ground in it.

This mixture is screwed onto the hollow shaft e and circling with the same scrapers ρ through a circular central section of the partition wall ^{o 1} on the ^{blades Z 1 of} the second conical drum c ¹ .

The wings Z ¹ now throw this mixture against the sieve m ¹ , whereby the good flour is collected in space jB and carried away by rotating wings q through a pipe F , while the grits through a circular opening in the partition wall o ² onto the third wing drum c ^{2 is directed} with the working wings Z ² .

After the grit has penetrated the sieve m ² , it now falls down as good grit in room C and is discharged through further wings q ^x through pipe G, while the vapor through a circular opening into room D and out of this into the waste pipe J falls.

The arrows shown in the drawing indicate the process and the path of the Grist exactly specified.

Claims (1)

Patent Claims: i. A sifting machine in which the existing sieve surface is used is increased that the grist cone by throwing the axis of rotation is set perpendicular, against enclosing sieves of conical upward (not downward) tapered shape is thrown. A visual machine of the under ι. The way in which the introduced grist is broken down into bowls, semolina, steam and flour is effected by means of a single passage in such a way that the grist passes through throwing cones (cc ¹ C ² J first against the widest-meshed conical sieve (m), then against the finest sieve (m ^l ) and finally thrown against a sieve of medium mesh size (m ² ) , the shells being discharged through a hollow shaft (E), the flour, fumes and grits through discharge vents (FGJ) .
