APPARATUS FOR MOLDING MASSE-QUITE.

SPECIFICATION forming part of Letters Patent No. 616,679, dated December 27, 1898.

Application filed December 29, 1897. Serial No. 664,408. (No model.)

.To @ZZ whom t may concern:

Be it known that I, LEOPOLD MAY, a subject of the Emperor of Austria-Hungary, residing in the city of Vienna, in the Empire of Austria-Hungary, have invented a new and useful Improvement in Apparatus for Molding Masse-Ouite and Analogous Substances into Bars or Strips, of which the following is a specification, and for which there have been granted an Austrian patent, No. 47/4,1l7, dated October 28, 1897, and a Belgian patent, No. 130,687, dated September l5, 1897.

This invention consists in the combinations hereinafter described and. claimed of moldbodies and cores and appurtenances thereof by which partly-Huid substances, such as the masse-cuite of sugar-renners, are molded into bars of a desired cross-sectional form and treated with clairce or any liquid clarifying agent.

Figure l of the accompanying drawings shows, partly in longitudinal section and lpartly in elevation, abar-molding apparatus embodying my invention. Fig. 2 shows in part a plan and in part a horizontal section; Fig. 3, a transverse vertical section. Figs. 4, 4a, 4b, 4C, and 4d illustrate in horizontal section, on a larger scale, various forms of the mold body and core.

Two important elements of the apparatus consists, as may be understood by reference to Fig. 4, of a hollow mold-body ct and a hollow core a of suitable form. In the example represented in that ligure the mold-body consists of an upright tube of square horizontal section open at top and bottom, and the core is a tube of cross-shaped horizontal section closed at the top and bottom, the edges of the arms of the cross fitting within the walls ofthe 1nold-box, so as to form therein four cavities 0.2,' which are open at top and bottom and which constitute as many molds, into 'which the mass to be molded-massecuite, for example-is charged for the purpose of producing bars, strips, or slabs.

The mold-body a and core a' are preferably made conical or tapering upward in the direction of their length for the purpose of facilitating the removal of the core with the molded bars, strips, or slabs from the tubular moldbody in a direction lengthwise of the latter. Such a mold-body and core may of coursebe made of any other suitable cross-section. Thus, for eXample,'in Fig. 4 the mold-body a is made of an oblong rectangular cross-section, into which there is inserted a core consisting of a tube a of cross-shaped cross-section, which is closed at top and bottom and has two short and two long arms corresponding with the inside of the tube, so as to form in the tube or body a four cavities a2 or molds of oblong rectangular cross-section for the production of slabs from the masse-cuite.

In Fig. 4b the tube a, constituting the moldbody, is of square cross-section, and into itis inserted the inner tube a', closed at top and bottom, which constitutes the core and which is also of square cross-section, the four side walls of said tube Ct severally projecting outward beyond the adjacent side, so as to form wings a* and form in the tube or mold-body a the four hollow mold-cavities a2 (which are also of flat rectangular cross-section, for the reception of the masse to be molded.

In Fig. 4c the tube or mold-body is represented as circular in cross-section, and the inner tube or core a' is of corresponding crosssection, but has provided on it oppositelysituated projections or ribs aomunning lengthwise of it. By this means there are formed in the tube or body a two mold-cavities a2 of semi-annular shape in cross-section for the reception of the masse-cuite, so that therefore in this arrangement two bars of semiannular cross-section are produced.

Obviously the tube ct and core a may instead of being cylindrical have an elliptical or similar cross-section. f

The core ce of cylindrical cross-section may,

as shown in Eig. 4, alsobe made without the projections ctothat is to say, it may have a smooth outer surface and be inserted in the outer tube or mold-body ct, so that in the latter there is formed only a hollow space a2 of annular cross-section for the reception of the masse-cuite. I/Vith this arrangement there is therefore formed only one bar of annular cross-section.

The two last forms can be made easily and roo cheaply, and also the formation of the bars of sugar or the like iu these molds has been found to be extremely advantageous.

As shown in Figs. l to 3, any desired number of the above-specified mold-bodies a, of which the form shown in Fig. is selected by way of example, are associated together and fixed at their upper and lower ends, respectively, into frames b and b', provided with handles b2, and the hollow bodies thus united in a group or a bundle are placed upon a tight drainage-box c and attached thereto by means of clamping-screws c', provided on the latter.

The mold-bodies c may of course be fastened singly in frames b b', provided with handles, and be attached upon the box c. This is particularly advisable in cases where the mold-bodies u are of large size, as shown, for example, in Fig. 4a.

The box c is provided at its upper surface with apertures, which are surrounded by packing-surfaces and correspond with the lower mouths of the bundle of mold-bodies placed upon it, which apertures are adapted to be closed by means of plates c3, which can be moved up and down from outside the box c by means of suitable adjusting devices c2- nuts and screws, for example. YVhen raised, the plates c3 constitute the bottoms of the mold-cavities a2, which are formed in the mold-bodies a by the inserted cores c,as shown at the right hand of Fig. 3.

From the bottom of the box c there projects an outlet c4, which is common to all the apertures in the top thereof and which is connected with an air-pump c5. -Upon the upper frame b of each bundle of molds there is placed a cup-shaped receiver which is open at top and bottoni and is provided with handles on its sides and with a packing edge on its under surface and into which receiver is introduced the iluid masse,which Vruns therefrom into and lls the hollow mold-spaces a2, formed in the mold-bodies a.

Into the receiver d there is inserted a perfoi-ated plate e, which is provided with handles c* and which forms at the same time a removable bottom for said receiver, and to the perforations of which there are connected upwardly-projecting tubes c', which are situated exactly over the mold-cavities a2 of the bodies a and which have a cross-section corresponding exactly to that of said cavities.

By inserting the plate or bottom e into the masse, which is still fluid and in excess in the receiver CZ, the masse is forced into the tubes e', and thus in addition to making up fory the contraction of the masse caused by settling in the mold-spaces also forms feeding-heads for the molded bars, which feedingheads can be separated quite smoothly by lifting off the plate or bottom c from the soliditied bars.

After the removal of the plates e the clairce is poured into the receiver CZ, which sits tight upon each bundle of molds and which also constitutes a measuring devicefor the necessary amount of clairce, and then the plates c3 are moved down by means of the adjusting devices c2 until they bear against rubber disks c6, (see Fig. 1,) which serve to make tight joints for the apertures of the plateadjusting spindles. Then the air-pump cS-is set in operation, whereby the drainage-box c is deprived of air, and the molasses is drawn by suction from the sugar bars and its place is taken up by the clairce.

Vhen the whole of the clairce has entered the sugar bars, the suction process is interrupted, and after loosening the clampingscrews c' all the bundles of'molds are moved from the drainage-box c and are placed into a centrifugal apparatus, (not shown,) which expels the superfluous clairce from the sugar.V After the bundles of molds have been removed from the centrifugal apparatus the molded bars or slabs are loosened one after the other by means of any suitable loosening apparatus and then removed from the molds to be further dried, if necessary, by any suitable means.
