IKEANS FO'R REMOVING COMPBESSED MATTEB-FROM CONTAINERS.

.--;App1i'cation' fi1edJune 11, 1927, Serial K053198984, and in'Ger-many June-15,1926.

When a powdered mass, compressed there-always remain residues in the containers which, owing to sure exerted thereon, become compressed into solid cakes that-firmly adhere to the bottoms of the containers and special means are required for the removalthereof.

Various devices are already known for this I Thus one well :known device con-. a beam removably fastened to the purpose. sists of container and which carrles a-manually operated threaded spindle which when pressed v press simultaneously against the bottoms of the containers. Y

All these well known devicesrequire-more or less time and labor and, if notoperated mechanically or manually specialhy'draulic presses or the like are required that have to be simultaneously operated; as they do not work automatically.

The present invention obviates all these drawbacks by providing the hydraulic press used for the compression of the mass with means which automatically will be impelled by the movement of the hydraulic pressure piston.

My invention will be more fully understood by reference to the accompanying drawing in which similar reference characters denote corresponding parts and in which Fig. 1, is a vertical section of a hydraulic cacao press equipped with my invention; p

Fig. 2 is a cross section thereof; Fig. 3 isa side view thereof; Fig. 4 is a section on line 1-1 of Fig. 1 and Figs. 5 and 6 detail views of the hydraulic piston and pressure head.

A denotes the stationary frame of the hydraulic press and 19 the piston thereof. Each side of the frame is provided with a number of horizontal guide grooves (1, arranged in vertically superposed manner. 19 has fixed to its upper end centrally a pressure head 13. Each container or vessel in which the mass is to be compressed has a vertically movable bottom 6 and is provided such as cacao, is

the high prescounterbalanced the The piston with diametrically opposed lateral projections 0 to slidably engage the-guide grooves a n the frame A. In the presentexample twelve containers 1-12 are shown, of which slX are adapted tobe simultaneouslyin operation for compression of the mass and six to be atthe same time inthe position for theremoval of the compressed mass or cake therefrom. In the position for the compression of the'mass six of thecontainers, as 1 to 6 are stored centrally overthe piston1-9 or its head piece 13 in a vertical column with re movable press blocks 14, 15 16, 17 and 18, lnterposed between'them while theother-containersare supported at the sides of the frame, three at one side, another three at the opposite side, the two sets being vertically displaced relative one another A (Fig. 1).

Movably suspended by cords d and by weights 54, are two stepped frames formed with beams 38- 11,

and of which one has steps 424%1 and the other 45-47. Each'beam-is provided with notches 56 59 and 6068. The steps 42- 17 centrally support ,pressure plates 48-53 adaptedto register with the central parts of the bottom of the laterally withdrawn containers 712. 1

Projecting laterallyffrom the headpiece 13 at diametrically opposite sides fare two rigidarmssofll eachbearing'a roller 20. Four substantially T-shaped levers 22-25 are fulcrumed at 26-29 in the frame A and are formed at their free ends with

cam portions

30, 32 and carry pivoted fingers34-37. The mode of operation of the device is as follows:

In the position shown in Fig. 1 the containers 7-12 are ready for the removal of the cakes while the contalners 1-6 containing freshly filled material are ready for compression. When the piston 19 rises to comress the mass in the containers by the heads 13-18, the rollers 2O of the

arms

20 and 21 roll over the cam portions 30-32 of the angular levers 2225 and thereby swing latter on their fulcrums 26-29. Through the engagement of the fingers 8437 in the notches 5657 the stepped frames are simultaneously moved upwardly carrying with them the pressure plates 428-5 3 which press against the bottoms b of the containers 1ifting the same together with the cakes deposited thereon. "When the rollers 20 of the arms 20*2 1 reach the inner corners of the cams 89- 33 the bottom of the containersaresulliciently lifted to permit the removal of the cakes. As the hydraulic piston continues to rise the rollers 20 roll ofl" the mner edges of the'cams as a result ofwhichi the levers 2225, and with them the stepped frames and the bottoms of the containers- -19 after the completion of its compression' stroke moves downwardly and thereby again swings the levers 22-25 upwardly the stepped movable frames and pressure plates 48 53 be not raised as this would result in the removal of the material from the conftainers 7-12 before the same has been compressed. On the completion of the compression of the mass in the containers the latter are removed from the column and replaced by the containers 712. But before the exchange of the containers one of the stepped l'rames having the beams 10 if and 4:1 is vlowered suiiiciently to permitthe

fingers

36 and 37 to engage the notches 58' and 59 and after the exchange of the containers the other stepped frame having the

beams

38 and 39 is lifted to such an extent ,as to permit the fingers 34 and to engage I the notches 60 and 61. Thereupon the operation can begin anew. 7

It is understood that various other motion transmitting means may he used without departing from the principle of'my invention.

It is also understood that the removal of thelcakesfrom the containersmay be made [to take place during the returnstroke of the piston. The operation of the device for the removal of the cakes is advantageously so timed that the same will be completed at the time the piston 19 on its return starts its compression stroke. This is done not because it is desired to avoidthe pressure necessary-being added to that for the compression of the mass but because during its return stroke the piston may be allowed to move faster than after the expression of the oil from the cacao has begun. 1

-What I claim is: l

1. In a device'for removing from a container having a movable bottom a mass, such as cacao cake, compressed therein, thecombination with a power operated piston for compressing said .mass, of means impelled from said piston for raising the bottom of said container. r

2. In a device for removing from a container having a movable bottom, a mass, such as cacao cake, compressed therein, the combination with a power operated piston for compressing said 4 mass, of means impelled rom said piston and including cam controlled members adapted to actagainst the bottom of said container. 7

3, In a device for removing from a-con tainer, havinga movable bottom a mass, such as acacao cake, compressed therein; the vcom- 'bination with a power operated piston for compressing said mass, of means impelled from said plston and including cam :con-

trolled frames and means operated from said i frames and: acting against said movable bottom to raise the latter during the'ret urn stroke of said press.

In testimony whereof I 'aiiix my signature.
