APPARATUS FOR TURNING MALT.

SPECIFICATION forming part of Letters Patent No. 505,945, dated October 3, 1893.

Applicationfiled June 28, 1893- Serial No. 279,019. (No model.) Patented in Germany April 20, 1887, No. 43,549, and in v Austria-Hungary .Tuly 10,1888,N0. 12,920 and No. 21,087.

To all whom it may concern.-

Be it known that I, FRANZ HOCHMUTH, of Dresden, in the Kingdom of Saxony, in the German Empire, have invented certain new and useful Improvements in Apparatus for Turning Malt on Kilns and for Like Purposes, of which the following is a specification, and for which I have obtained patents in Germany, No. 43,549, dated April 20, 1887, and in Austria-Hungary, No. 12,920 and No. 21,087, dated July 10, 1888.

This invention relates to rotary apparatus for periodically or continuously lifting and turning over grain, malt or other material while spread out in a layer on a floor for the purpose of airing or drying said material.

In carrying out my invention I employ a series of shovels attached to a rotary shaft in a carriage to which is given a reciprocating movement back and forth over a floor on which the grain, malt or other material is spread.

My improvement consists in the construction and means of controlling the operations of said shovels as hereinafter described and claimed.

I will proceed to describe the improvement with reference to the accompanying drawings and afterward set forth its novelty in the claim.

Figure 1 shows a cross section of the apparatus for lifting and turning the malt which is spread in a layer on the perforated floorD. Fig. 2 represents a partial front view of the same apparatus, the gearing for rotating the lifting and turning apparatus being in section. Fig. 3 shows aside view of the gearing for rotating and advancing the apparatus. Fig. 4 is a ground plan partly in section corresponding with Figs. 2 and 3.

Similar letters of reference designate corresponding parts in all the figures.

A is ahollow shaft extending over the width of the perforated floor or kiln D. The hollow shaft A rests at its two ends in bearings in the two sides of a carriage W. On one end of this shaft A, a chain wheel R is fixed over which passes an endless chain 8, which by means of the counter chain wheels R is forced to enter into the teeth of the chain Within these rails and above the bearings of the shaft A, racks n are fixed.

Upon the shaft A a pinion P is arranged, taking into the larger spur wheel T which is keyed on the same shaft with the pinion U which takes in the rack n. Thus the rotary motion of the shaft A is transmitted to the carriage W by thewheels P T U and rack n,

causing the carriage to travel along over the kiln at a speed relatively slow to the rotary motion of the shaft A.

On the shaft A are mounted arms B at the ends of each of which a two-bladed shovel is hinged or pivoted so that the two blades :1: y of each of said shovels which are substantially at right angles to each other, may enter into any of the positions-shown in Fig. 1. According to the direction in which the carriage travels over the kiln D, the blade or: or the blade y of each shovel will assume a position tangential to a circle having the axis of the shaft A for its center in which position it will enter into the malt on the floor D and lift it while the other blade 3 or x will occupy a position radial or approximately so to the said shaft and close to the arm B to which the shovel is pivoted. On the arms 13 there are loosely mounted annular slides or sliding pieces F. each provided with two projections 5, 6, one on each side of its respective arm. These slides will drop when the arm B comes into its lowest position and by dropping one of the projections will catch the one blade of the shovel which lies close to the arm while the other blade digs into the malt for lifting the latter; the slide E will now automatically lock or retain the shovel in this position while rising with the rotation of the shaft A, so that the shovel in so rising will lift the malt and will gradually allow the malt to fall or drop through the air until the arm B comes into such elevated position that the slide 'E by its own weight slides back to ward the shaft A and thus automatically releases the shovel leaving it free to turnon its pivot as indicated on the upperwarmB in;

one of the latter will always, come into ac-. tion, that is to say, to retain-the shovel with its load in due position whether the carriage with the apparatus is travelinginrthecidirec= tion indicated by the arrow in Fig. 1 or traveling in the reverse direction. It is furthermore obvious that the arms B on the shaft A should be placed or situated on the latter'alternately -inw such. a manner that the shovels C will allow no part of the layer of mal-tto remain untouched so that all the malt is lifted, airedand dropped al'li oven the surface of the kilnra What I flclaimriasimy inventioni' is-k- In: an apparatusforqturning malt and other substances, the combination with a rotary shaft 3 and attached arms, a series of twobladed shovels having their respective blades at an angle to each other and pivoted to'said arms, and slides on said arms for automatically engaging either ,of the two blades of each of said shovels with its respective arm for holding said shovels in operative positionsrwhen loaded :and automatically releasing saidshovels and leaving them free to swing on said arms when unloaded, all substantially as herein set-forth.

In testimony that "I claim the foregoing as myinvention" T have-1 signed myname in-presence of 'twoisubscribing witnesses.
