MALT-SPREADING-OUT APPARATUS.

Application filed April 1, 1909.

To all whom it may concern:

Be it known that I, GREGOR \VEINBEER, a citizen of the Empire of Germany, residing at Nuremberg, in the Empire of Germany, have invented a new and useful Malt-Spreading-Out Apparatus, of which the following is a specification.

As is well known, grain is malted by first soaking it with water and then heaping it upon a malting-floor in high and narrow couches, where it is allowed to germinate. During the process of germination it is necessary to remove from time to time the then uppermost layer of grain'and to hoard it up at the side of the couch, which is thus gradually spread out, so as to insure uniform germination throughout the whole mass. This spreading-out of the couches was hitherto effected by hand, which is objectionable for two reasons. One reason is, that the then uppermost layer of grain is not removed in a regular and uniform manner, and the other reason is, that this hand-work takes up much time.

My invention which is adapted to uniformly spread out a couch, while the thickness of the layer to be removed can be adjusted.

The apparatus comprises a crane adapted to travel on rails over a malting-floor, a frame suspended from the crane, a second frame vertically guided in the frame and extending over the whole length of the crane, one or more endless chains mounted in the second frame to move over rollers and provided with ladles having vertical central ribs, means for simultaneously driving the crane and the endless chain or chains, and means for vertically adjusting the second frame in the frame. The lower parts of the endless chains are parallel to the maltingfloor and the central ribs on the ladles form a continuous wall, which prevents the grains in the then uppermost layer from simply shifting to a side in the direction opposite to that in which the crane travels. The central ribs on the ladles also enable the apparatus to correctly work, no matter whether the crane moves on the rails in one or the other direction.

I will now proceed to describe my invention with reference to the accompanying drawing, in which Figure 1 is an elevation of an apparatus having two endless chains with ladies and adapted to spread out a couch disposed in Specification of Letters Patent.

the middle of the malting-floor, a part on the right being broken away, Fig. 2 is a vertical cross section through the same on the line AB in Fig. 1, Fig. 3 is a plan view of the same, parts being broken away, and Fig. a is a perspective view of av ladle with a central rib.

Similar characters of reference refer to similar parts throughout the several views.

Two parallel rzils are secured on suitable supports 3 above the malting-floor do on both sides for example in walls a7. On these rails a four wheels 2, 2 of a crane l of any known construction are mounted to roll. A horizontal shaft 8 is mounted in the crane 1 to turn and has fastened on its ends two gear wheels 9, which mesh with two racks 10 fastened at the rails a. An electromotor 5 of any known construction is disposed on the crane 1 and can be supplied with current from some source in any know-n manner. The armature shaft of this electromotor '5 carries a pinion (3 and a gear wheel The pinion 6 meshes with a gear wheel 7 fastened on the shaft 8 mentioned above, while the gear wheel 33 meshes with another one 32 fastened on a short shaft- 1S, which is mounted in the crane 1 to turn. I have merely indicated the bearings for the shaft 18, also the outer bearing for the armature shaft by thick lines, as they may be of any known construction and may be fastened on the crane 1 in any known manner. have also not shown any bearings for the shaft 8 for the sake of simplicity, as it is obvious to any expert how they can be disposed.

A frame is suspended from the crane 1 and is shown to consist of two parallel horizontal angle-

bars

11, 11, eight vertical rods 12, 19., four vertical studs 13, 13 and eight struts 1a, 14.

A second frame is vertically guided in the first frame and is constructed as follows. Two parallel horizontal angle-bars 18 are connected with one another near their ends by two brackets 15 and near their middles by two

brackets

16, 16, which brackets are all provided at their ends with

eyes

17, 17, that are guided on the

vertical rods

12, 12. The four brackets 15, 16 are in their middles rigidly connected with four vertical racks 3-1 3st, which mesh with four gear wheels 36 fastened on a horizontal shaft 35, that extends over the whole length of the crane 1. The shaft is mounted to turn in bearings,

which'are equally merely indicated by thick lines and can be disposed on the crane 1 n any known manner. A worm 'whee1'37 1s keyed upon the shaft 35 and meshes with a hand-wheel .39 by means of its shaft 40. I

' have also merely indicated by thick lines the I ism any a bevel wheel 30 bearings for the worm shaft 40 for the sake of clearness. 1

The two horizontal bars ,18, 18 are provided with suitable holes or eyes, in which five shafts 49, 49 are fastened. On the middle shaft 49 two

rollers

19, 19 are mounted to turn, while on the other shafts 49, 49 only one roller 19 each are mounted to turn. The

eyes

17, 17 of the two

inner brackets

16, 16 are in pairs connected together by horizontalbars 24, '24, in which the shafts of two preferably octagonal driving rollers 22, 23 are mounted to turn. These two shafts are geared together by means of two

gear wheels

25 and 26. In

' the bar 24 on the left in Fig. 2 the lower end of a vertical shaft 28 is mounted to turn, while it is' in any known manner prevented from vertically moving. The shaft 28 is put in gear with that of the driving roller 22 by means of

bevel wheels

29 and 27. The shaft 28 passes through some bearing (not shown) in the crane 1 and through upward and is longitudinally splined (Fig. 1). The bevel wheel 30 known manner prevented from longitudinal motion on the shaft 28,and meshes with another bevel wheel 31 keyed upon the shaft48 mentioned above. It will be seen, that the bevel wheel 30 can drive the vertical shaft 28 for any position of the second frame described above. An endless chain 20 indicated by dotted lines passes over the driving octagonal roller22 and three guiding

rollers

matter, whether the crane 1 travels in oneor the other direction. 'As both the two end-} motions of the; r 7 i crane l and of the endless series of ladles take place at the same time, it is obvious, that each ladle 42 is enabled to cut a fresh furrow following that cut by the preceding ladle 42. As the uppermost layer is removed by the two endless series of ladles to both sides of the couch, it is obvious, that the malt can be gradually spread out by the apparatus, until it covers the whole maltingfloor 46.

The malt spreading-out apparatus can be varied in many respects without departing from the spirit of my invention.
