G. SGHIUHT. GRYSTALLIZING APPARATUS.

APPLICATION FILED JUNE 27. 1905 GEORG SOHIGHT, OF VIENNA, AUSTRIA-HUNGARY.

CRYSTALLIZING APPARATUS.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed June 27, 1905. Serial No- 267,229.

To all whom it may concern:

Be it known that I, GEORG Sornolrr, subject of the Emperor of Austria-Hungary,resid- 1 branches.

ing at Vienna, XXI Leopoldau No. 1 19, in the Empire of Austria-Hungary, have invented new and useful Improvements in Crystallizing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use the same.

The invention relates to a new and useful apparatus for crystallizing solutions in general but crystal soda and Glauber-salt in particular, the object being to provide an apparatus which allows crystallization to take place in the whole of the space used and further enables easy removal of the separate cells and crystals afterwards. I attain this object by means of an apparatus comprising a multitude of cells independently from each other suspended from the borders of a re ceptacle destined to contain the crystallizing solution, the cooling liquid being introduced into the said cells through channels provided in the cell suspending means and therefore in parallel and independent Such an arrangement facilitates the easy removal of any cell as well as the separation of the crystals adhering to the outer wall of the cells and also allows of any suitable adjustment of the cells within the receptacle containing the crystallizing solution.

In the accompanying drawings I illustrate, by way of example, an apparatus according to my invention, without, however, limiting myself to the shown device, as the same may be varied in forms, details and accessories without departing from the principle of my invention.

Figure 1 is a vertical sectional view of a receptacle containing the solution, with the apparatus according to my invention partly in section and partly covered by the settled crystals; Fig. '2 is a plan view of the arrangement according to Fig. 1 and, Fig. 3 is a view showing the apparatus for crystallization partly in section and partly in elevation.

The apparatus is composed of several hollow cells 3 which preferably consist of narrow pockets, their length or depth respectively being smaller than the width or height respectively of the receptacle 2, as

clearly shown in Fig. 2. A certain clearance between the bottom parts of the cells and of the receptacle is advantageous, as hereby the impurities contained in the solution are allowed to settle on the bottom of the .receptacle.

In order to suspend the cells in the receptacle the cells are provided with arms 4 and 5 respectively, projecting outwardly over the walls of the receptacle. These arms may consist of single U-shaped bars 6 extending across the receptacle and slotted in their middle parts 7, the length of the slot corresponding to the length of the cell 3. The cell is guided through this slot and fixed to the walls of the bar in a suitable manner, the top part of the cell remaining open. The one end of the bar 4 may be closed as shown in Fig. 3, while the other end may be used as a discharge port for the cooling liquid. The cooling liquid is introduced by a pipe 8 into the excavated arms, near to their closed ends wherel'rom it llows into the cells, and thence by the free arm ends 5 into a suitable discharge receptacle. After a short period the crystals begin to settle on these cells. After the crystallization is finished the remaining solution is run oil, the cells are lifted out of the receptacle and the crystals are separated from the cells either by shocking or beating the cells or by warming their cooling medium to such an extent as is necessary to allow the crust of crystals adhering to the walls of the cells to melt and drop off. They may be allowed to dro into transport receptacles or into another iquid or the like directly for the further processes.

It will be readily understood that by a suitable arrangement and corresponding adjustment of cocks and the like and also by suitable displacement of the cells the admission of the cooling liquid, the thickness of the settled crystals and. the duration of the crystallization may be varied at will.

l V hat I claim as my invention and desire to secure by Letters Patent is 1. In combination, with a receptacle for containing crystallizing solutions, an apparatus comprising a multitude of cells, channeled arms independent from each other and suspended from the borders of the said receptacle, each of the said arms serving as support for, and communicating with, one of the said cells, means to admit cooling liquid at one end of the channels of said arms and to discharge the cooling liquid at the ofl gp end of the channels of the said arms, substantially as described. r

2. In combination, With a receptacle for containing crystallizing solutions, an apparatus comprising a multitude of cells, slotted U-shaped bars independent from each other and suspended from the borders of the said receptacle, the said cells fixed to the slotted parts of the said bars, and means for admitting a cooling liquid to the said cells by Way 10 of said bars, substantially as described. In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
