GERMINATINGr-D RUM.

Application filed April 8, 1912.

T0 ZZ wim/n. it mujl/ concern Be it known that I, LUDWIG Torr, manufacturer, of Erfurt, in the Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improvements in Germinating-Drums, of which the following is a full, clear, and exact description.

,This invention relates to devices for working grains, and pertains more particularly to devices of the rotary drum type in which seeds, malt, and various other grains are treated for germinating purposes.

The object of the invention is to provide an improved germinating drum which combines simplicity and compactness with effective operation.

The present apparatus is capable of receiving and working several different bodies of grain simultaneously, each body being inl a different state of germination, and the different germinating compartments are so interrelated that all are adapted to be coun pled together and driven as one drum from a single power source.

In the drawings which form a part of this specification, Figure l is a longitudinal sectional view of the apparatus, showing the different compartments and the therewith associated parts, Fig.,2 is a sectional view taken on the line 2-2 of Fig. 1, Fig. 8 is a longitudinal section of a modified form of the device, Fig. 4l is a section taken on line 4 4 of Fig. 3, Fig. 5 is a longitudinal section of a second modification, and Fig. 6 is a section taken `on line 6 6 of Fig. 5.

Referring more particularly to said drawings, a hollow shaft l is fiXedly supported in suitable standards and carries a series of rotatable drum elements 2. Said elements 2 are identical in form and size, and are of any desired or suitable number, in the present instance, four being shown. The elements or sections 2 are open ended and are supported directly by a plurality of division disks or plates 3, which are nonrotatably mounted on the shaft 1 and are provided on each face with the bearing rollers li. Said rollers l are of such size and in sufficient number as to afford solid bearings for the sections or elements 2 between the plates or division disks 3, so that said sections 2 may revolve as independent drums. The edges of the sections 2 are brought into such intimate contact with the plates 3 that there will be no leakage of Speccaton of Letters Patent.

grain therefrom, and practically no leakage of water or air during the working of the cylinders. Each section 2 is provided with a driving ring 5 into which or against which the friction rollers 6 bear to drive the several sections 2. Said rollers 6 are mounted in yokes or frames 8 which are pivotally mounted on a shaft 7, so that they may be oscillated to swing the rollers 6 into and out of contact with the driving rings 5 on the drum sections 2. Said rollers 6 are also provided with secondary pulley sections for connection with a main driving shaft or other source (not shown). The frames 8 are operatively connected to the spindles 7, which are in turn threaded into suitable standards 8, whereby, by revolving the hand-wheel carried by said spindle 7, the frames 8 may be swung for the purpose above mentioned. It is evident that instead of the friction drive shown, any equivalent driving device may be substituted.

In order to permit the entire set of drum sections to be driven at one time and by a single drive wheel, if desired, means is provided for locking all of the sections 2 together. To this purpose, the drums are suitably provided with the bolts 9 and the latches lO.

By the mechanism above set forth, it is possible to operate the sections 2 in any desired number or in any desired combination. By means of the adjustable driving devices mounted on shaft 7, adjacent or alternate sections can be operated, and by using the bolts and latches 9, 10, a combination of adjacent sections can be driven by one of said driving devices.

The division walls or plates 3 are joined within the drum sections 2 with the pipe sections ll, which are formed of perforated sheet-metal, said pipe sections being rigidly connected to said plates or walls, and forming in each section a central passage way or chamber which is screened off from the rest of the drum. All of the pipe sections 11 have the same diameter throughout the length of the apparatus, so that in effect, a central conduit, subdivided into a plurality of sub-chambers equal in number to the number of drum sections 2 is provided. EX- tending through the end section plate or wall 3, at the left in Fig. l), are a series of pipes l2, equal in number to the number of drumy sections 2, and one of said pipes 12 is projected through the conduit formed by? the pipe sections 11 and through the plates or Walls 3 to each of the sub-chambers formed by the pipe sections 11 between the plates 3, so that each sub-chamber is supplied With air through a separate and isolated air pipe 12. The air issuing from said pipes 12 fills the sub-chambers and then passes through the walls of the latter into the drum section 2. The outer or exposed ends of the pipes 12 project into a common supply conduit 13 which is fixed to the end plate 3, above mentioned, from which the several chambers and the drum sections are supplied with air. Suitable cutoff' valves 13 are provided in order to permit the regulation of the air supply to isolate any one or several of the drums in order to meet the requirements of the operation of the apparatus.

Referring noW to Figs. 3 and 4, the fixed shaft 1 is'provided with a series of rigidly mounted trunnions or bearings 16, upon which are rotatively mounted the end plates 15 of the drum sections 2, the end plates in this construction Vbeing secured to the peripheral portions `of the drum sections, so as to form a complete drum of each section. The perforated pipes 11 are also carried by the plates 15, so as to revolve therewith. The trunnions or bearings 16 are used in this structure to support the pipes 12, and the air supply connections are the same as shown in Figs. 1 and 2. The drum sections are driven as herein before described, by means of the drive rings 5.

In the construction shown in Figs. 5 and 6, a hollow cylindrical frame, consisting of longitudinal rods 2O and the end and intermediate annular plates 19, carries a plurality of annular bearings 17 as rigid parts of said frame. The bearing members 17 are journaled on the collars 17 which are connected by a series of rods 24, which form a rigid structure supported by the standards or trunnions 25 and 26. A Worm gear 23 carried by one end of the frame structure is driven by a Worm 22 to rotate the Whole frame structure. IVithin the spaces divided olf by the-several plates 19 of the frame, are mounted the drum sections 2 having the end Walls or plates 15. Said plates or Walls 15 are provided with the central journals 18, which are journaled on the bearings 17 so that the several drum sections 2 are freely rotatable Within the frame structure. Lock and latch members 9 and 10 are provided so that the drum members can be locked to the frame to be rotated thereby, as desired. Adjacent the division plates of the several drums, and carried by the collars 17 are the transverse plates 21, Which form a plurality of sub-chambers in the central space formed by the drum sections. The pipes 12 are extended through said sub-chambers, as described in connection with the foregoing descriptions, and are similarly connected to air and Water supplies.

Having thus described my invention, what I claim is 1. A germinating drum, comprising in combination, a plurality of independently revoluble drum sections, a common axis for all of said drum sections, means for supplying a gaseous fluid to each drum section independently of the others, means for driving each drum section and .means for locking said sections together to rotate as a unit.

2. A gerininating drum, comprising in combination, a plurality of drum sections, a common axis around which all of said drum sections rotate, a series of central chambers formed around said axis and corresponding to said drum sections, means for driving said drum sections independently of each other and means to supply a gaseous fluid to said drum sections through said central chambers.

, 3. A germinating drum, comprising in combination, a fixed axis, a series of drum sections revoluble around said axis, a continuous series of central chambers extending through said kseries of drum sections, means forV driving each of said drum sections, and means for supplying a gaseous fluid to said sections through said series of central chambers.

4. A germinating drum comprising in combination, a fixed axis, a series of division members carried by said axis, a series of drum sections mounted to revolve on said division members, a central area extending through said series of sections and divided by said division members into chambers corresponding to saidr drum sections, means for driving said drum sections and means to supply a gaseous fluid to said drum sections through said central chambers independently of each other.

5. A germinating drum, comprising in combination, a plurality of independently revoluble drum sections, a common axis for all of said drum sections, means for supplying a gaseous liuid to each drum section independently of the others, and means for driving said drum sections in selected combinations.

In testimony whereof I affix my signature in presence of two Witnesses.

LUDWIG TOPF.
