' March 14, 1961 A. MALDARI MACARONI DIE Filed April 25, 1960 m 0 D n N WI- 7 MM lo UAW tion illustrates a Brooklyn, N.Y., assignor to 1). Ma]- Inc., Brooklyn, N.Y., a corporation of Ralph A. Maldari, dari and Sons, New York The invention herein disclosed relates to macaroni dies and the general objects of the invention are to provide a simple one-piece die for producing macaroni or similar products in various, more or less complicated designs.

Particularly it is a purpose of the invention to provide adie of this character in relatively inexpensive, durable, practical form, which can be readily cleaned and kept in proper condition.

Further special objects of the invention are to provide a die' of the character indicated which will produce a high grade, uniform product and which, if need be, may be readily modified to insure uniformity in the product.

The foregoing and other desirable objects are accomplished in this invention by a combination of novel features of contruction and parts, all as hereinafter described and claimed and as illustrated in the accompanying drawing.

The drawing referred to forming part of this specificapresent practical embodiment of this invention but structure may be modified and changed as regards the immediate illustration, all within the true intent and scope of the invention as hereinafter defined and claimed.

Fig. l in the drawing is a top plan view of one of these new dies.

Fig. 2 is a bottom plan view of the same die.

Figs. 3 and 4 are cross sectional views of the die on substantially the planes of lines 3-3 and 4-4 respectively of Fig. 1.

Fig. 5 is an end view of a form of product such as may be produced by this invention.

As shown in the several views the die of this invention is in one integral piece in the nature of a disk or plate 7, circular in outline to seat in a corresponding opening in the bed of an extrusion press and having an external annular shoulder 8 for so supporting it in the press.

At the top the die body is provided with entrance openings for the dough or other material.

In the illustration there is an outer circular row of supply openings 9, an inner circular row of openings 10 and intermediate supply openings 11 between openings of the outer and inner rows, all as shown in Fig. 1.

At the bottom the die block is formed with a continuous outer circular slot 12 extending upwardly to the outer row of supply openings 9, an inner concentric continuous slot 13 extending upwardly to'the inner row of supply openings 10 and radial slots 14 connecting the inner and outer circular slots and extending upwardly to the intermediate supply passages 11.

This construction provides continuous communication between inner, outer and radial extrusion or exit slots and full access to these slots from the supply ports or passages in the top of the die.

Also the intervening portions of the die between the discharge slots are well and fully supported in the die 1 block. Thus the center post portion 15, Fig. 2 within the inner circular cut 13 is firmly rooted in the solid cenp, 7 2,974, 13 Pa en Man lebnlfitil tral portionlfi, Fig. 3, atthe top of the block and similarly the separatedsegmental portions 17, Fig. 2, between the circular and radial slots are firmly rooted in the solidperipheralparts 18 in the top ofthe block as shown inFi'g. 4. f l t This one-piece, diestructure therefore is amply strong and at thesame time free passage for the dough or other extruded material is afiorded to the outer and inner circular passages and the radial slots connecting the same.

Fig. 5 shows the resultant product as made up of inner and outer circular portions 19, 20 connected by radial webs 21.

It will be clear from the disclosure that various other more ,or less complicated extruded forms maybe produced by modifying the supply passages and connected slots or channels in various ways.

The die constructed as describedis relatively simple and inexpensive to manufacture, it is easily cleaned and is practical and efiicient in every respect.

Manufacture of the die block is simple. The outer and inner rows of supply ports and intermediate ports may be drilled in the top of the block and then the circular and radial slots be milled in the bottom of the block, in connecting relation. As an alternative, the slots may first be cut in the bottom of the block and then the supply passages drilled into connecting relation in the top of the block. In either event the center post and surrounding segments are left well-supported in the solid material in the top of the block with full access to the supply passages. As particularly shown in Fig. 4 a solid portion is left at the center of the block at 16 supporting the center post and a practically solid surrounding annular portion 18 is left for the support of the de pendent segments at 17.

This construction produces a well formed product of uniform wall thickness of attractive appearance as well as desirable in other ways.

If certain portions extrude faster than others the supply passages or exit slots may be modified to maintain substantially uniform flow at all points of the die.

The integral one-piece form of the die is important from the manufacturing and handling standpoint and also as a matter; of initial cost. Cleaning of this one-piece die is simple and mounting of the die in the press is a simple operation, particularly since there is no separate center pin such as has been necessary heretofore. Elimination of. the separate center pin also assures perfect centering of all parts of the products.

In this one-piece construction the upper half of the die is a solid cylinder perforated by an outer row of openings 9 and an inner row of openings 10 with intermediate openings 11 between theouter and inner rows, thus leaving solid imperforate segmental portions 18, Figs. 1 and 4 in the top to which the correspondingly shaped segmental portions 17 at the bottom are rooted and a solid imperforate central portion 16 to which the center post 15 at the bottom is rooted.

What is claimed is:

l. Macaroni die comprising an integral one-piece die body having concentrically related inner and outer continuous circular annular slots connected by radial slots, said inner and outer circular slots and connecting radial slots extending upward from the lower end into the midportion of the die body and supply passages extending from the top of the die body down into the mid-portion of the die body into communication with said circular between said outer and inner circular rows of passages in communication with said radial slots.

3. The invention according to claim 1 in which said inner circular slot in the lower end of the die body defines a central post and said inner and outer circular slots 5 together with the radial slotsdefine separate segmental portions surrounding the center post and in'which the upper end of the die block has a solid imperforate central portion to which said center post is joined and solid imperforate segmental portions between the supply pas- 10 sages to which said segmental portions are joined.
