MULTIGELLULAB MOLD.

' I Application filed March 2, 1922. Serial No. 540,437.

My invention relates to multi-cellular.

molds, more particularly for use in candy making. There is a candy piece well lgnown in the trade as a sucker which consists of a piece of hard candy provided with a stick or skewer by which the child may hold it when he is eating or sucking it. In the commercial manufacture of such pieces it is customary to form them in multi-cellular molds '10 which consist of a frame with cross part1- tions which are separable and removable and form the mold cavities. run crosswise of each other and of the mold frame, and when the frame is unlocked and the sides swung apart the partitions are taken apart and the candies released. These cross partitions are notched in such manner that their lower edges may all-rest on the bottom of the frame-that is, they are so notched as to interfit and while standing on edge all reach down to the floor of the mold frame. These partitions have certain disadvantages, for example, a good deal of time is required to interfit them at the notchesand properly assemble them in the frame.

Furthermore, the notches weaken the partitions, render them hard to keep clean and are otherwise objectionable. The general object of my inventionis to provide a mold which will avoid these objectionable features. Among the specific objects of the invention are to provide partitions free from notches; to provide partitions capable of all running in eneral 1n the same direction; and to provide partitions free from sharp corners which would prevent ,them from being readily cleanedr Another object is to provide a construction in which the partitions are all duplicates of each other and therefore interchangeable. Another object is to provide a construction which will avoid the formation of fins or undesirable flanges on the candy pieces.

'45 I attain my objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a top plan view of a mold embodying the invention;

Figure 2 is an elevation of the same, partly in'Fsection;3 fr t t ,1 are is a a en ary perspec 1v e, Y 8ll0Wilfl portion .of Iii; frame and a fragment o a artiti'on;

I Figure 4 1s a perspective view of a piece of These partitions candy which will result from'the use of a mold of this particular design;

Figure 5 is a fragmentary view showing a modified form of mold cavity.

Llkenumerals denote like parts through out the severalviews.

According to the design selected to illustrate the invention, the frame consists of two parallel longitudinal members 1 and two parallel transverse members 2 arranged in the form of a quadrilateral. At one end the transverse members are secured to one of the longitudinal members by studs 4, the outer ends whereof are extended and form handles 6, by which the device may be lifted. The remaining longitudinal member has projecting tongues 8 at each endwhich fit into channels 10, formed in the adjacent ends of the transverse members 2. These tongues are of smaller cross section than the longitudinal member of which,

they form a part and hence shoulders 9 are formed which abut the inner edges of the transverse members and keep them at the proper distance apart. The transverse members are preventedfrom spreading by pins 11 mounted in the outer ends of the tongues '8. Shafts 12 are mounted at the channeled ends of the transverse members and theseforn'i pivots for cams 14, which are rotated by handles 15 in such manner as to engage and release the longitudinal members 1. In other words, by rotating the cams to one position they will press the engaged longitudinal member inward towards the center of the frame while if the cams are rotated to another position they will release the member. The handles 15 serve not only to rotate the cams but also afi'ord means by which the frame may be lifted.

Now, referring more particularly to the mold cavities l6, and the elements which form them:

The partitions 18 are made preferably of strips of brass or other suitable metal. Their height, when assembled, is usually approximately equal to the height of thegeneral by the reference numeral 18.

Figures-1 and 2, but have indicated them in These partitions may be differently described by saying that they have fiat longitudinal sections arranged alternately in parallel planes and connected by oblique end sections. It

will be noted that when partitions of this 'the mold cavities while the candy is being poured and cooled. In order to carry out the shape of the piece at the ends of the partitions, the frame members 1, 2 have notches 30, 31, formed in their inner surfaces. As a result of this no incomplete castings are formed and the entire space between the frame members can be filled without causing waste or fragmentary castings. At the ends, the partitions abut the inner sides of the frame, thus making definite end contact and effectively preventing any relative shifting lengthwise which would tend to distort the mold cavities.

In practice, the partitions are assembled in the mold frame as illustrated in Figures 1 and ,2. The cams 15 are then rotated so as to press firmly against the outside of the adjacent member 1 and hold the parts closely together to avoid the formation of fins at the ends of the candy pieces. It will be observed that in each cell there are only two corners where fins can possibly be formed, viz, at the pointed ends of the cavities, whereas with the old fashioned molds where the partitions run crosswise of each other and are slotted so they may interfit,

' there are four corners where fins or other irregularities may be produced. Such fins detract from the appearance of the goods and it will be evident that my construction necessarily eliminates two out of the four possible places where they can be formed. There is another advantage in the form illustrated which arises from the fact that the partitions make surface contact with each other for approximately half of the length of the mold cavity. it will be noted that as the partitidns make surface contact at each end of each cavity they are firmly braced. This makes an exceedingly strong and durable construction and makes it practicable to lock the frame up very tightly without danger of injuring the partitions. As a matter of fact, when the par titions are made of 18-gauge metal or thereabouts, they are comparatively stiff and yet ea ers the molds becomes so nearly perfect that no tins can be formed.

It will be understood that incandy manufactories, apparatus is necessarily subjected to rather rough usage, but partitions formed in the manner described successfully resist even extraordinary wear and tear. from the fact that they are without notches orperforations of any kind and consist of a single, continuous, formed strip from end to end. It is evident that they are synnnetrical in the sense that there are no rights and lefts. By reversing them, either end for end or top for bottom, a single type of partition is all that is required.

I do not wish to be understood as confining myself to partitions of the exact conformation illustrated in Fi ures 1 to 3. The location and shape of tie bendsmay be modified so as to produce modified shapes of candies; for example, they may be square at the ends as shown in Figure 5. In such case the partitions 32 will make rectan lar pieces of candy; but, although the form shown in the ot er figures is preferable the appended claims are to be constructed with reasonable scope and without undue limitation.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent is:

1. A multi-cellular mold having a frame and a plurality of removable arti'tions therein running, in the main, paral el to each other, each partition having bends for creating mold spaces between it and the adjacent partition, and the frame having reeesses formed in the inner surfaces corresponding to the configuration of the partitions to thereby complete each mold cavity and prevent the formation of partial castings.

2. A multi-cellular mold having a frame and a plurality of removable partitions therein running, in the main, parallel to each other, each partition havin bends for creating mold spaces between it and'the adjacent partition, the end contact with the insides of the frame to thereby positively prevent relative shifting of the partitions and the formation of imperfect mold cavities, said frame being recessed to form continuations of and complete any incomplete mold cavities created y said partitions.

3. A multi-cellular mold having 9. rectangular frame and a plurality of partipartitions making 2 each other in the frame an tions runnin in the main, parallel with each other, t e partitions bein alike, and each consisting of a thin strip of metal having flat sections arranged alternately in separate parallel planes which form the sides of the mold cavities, and connecting portions which form the ends ofthe mold cavities, said connecting portions extending obliqnel to the general length of the partitions, t ereby producing cavities of hexagonal form, the flat sections of the stri s being of a length approximately half t e entire length of the mold cavity and the strips making end contact with the inner surfaces of the frame for positively preventing relative shifting of the partition.

4. A multi-cellular mold having four frame-members arranged in the form of a rectangle, partitions runnin parallel to bent at certain intervals to form mold cavities, said partitions being resilient to a moderate degree, and one of the frame members being movable toward and from the center of the frame, cams pivotally mounted in two of the frame members and adapted to engage the outside of the movable frame member to press it toward the center of the frame to bring the partitions into close contact with each other, and levers extending from'said cams for operating them, said levers also affording handles whereby the frame may be lifted, said cams and levers being located at opposite edges of the frame, and being rotatable in the plane of the frame whereby when the frame is lifted, the lifting force will have no tendency to rotate the cams.

In witness whereof, Ihave hereunto sub scribed my name.

DOMINIK M. BERN OTOW.
