MARIO TANZI, OF BROOKLYN, NEW-YORK.

DIE AND CUTTER.

Application filed October 17,1924. Serial No. 744,185.

To all whom it may concern:

Be it known that I, Mauro TANZI, a subject of the King of Italy, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented an Improvement in Dies and Cutters, of which the following is a specification.

This invention relates to dies for manufacturing tubular products and more particularly dies which co -operate withcutters for cutting the tubular products in prede-- termined lengths. i

It is an object of the invention to provide a labor saving construction for cutting on diagonal lines tubular products such as macaroni, as the same emerge out of the press. a

It is another object of the invention to provide a simple but effective construction for producing in one operation tubular products out on diagonal lines.

It is a further object of the invention to provide a macaroni die and cutter, which is simple in construction durable and adaptable to be used in connection with the ordinary macaroni press, and which permits the macaroni as it is molded tobe cut on diagonal lines as they are formedandcome out of the die, without further manipulation or additional machines.

Other and further objects of the invention, together with its advantages and distinguishing features, will appear as the specification proceeds, which specification is descriptive of one embodiment of the invention as illustrated in the accompanying drawings, forming'a part of the specification. It is understood that the said drawings only illustrate one example of my invention, that the specification is only descriptive of such an example as illustrated, and that I do not limit myself to the exact features illustrated, for it is manifest that the same can be easily altered, varied, and changed without in the least departing from the spirit of myv invention.

Referring to said drawings:

Figure 2 is a plan view of the aforesaid embodiment looking upwardly to the illustration shown in Figure 1;

Figure 3 is a view of a broken-off portion of the base die hereafter to be described and showing the outer face thereof;

Figure 6 is a cross sectional view of a portion of the die taken on line 66 in Fig; ure 2;

' Figure 7 is a side view of the pin which co-operates with the die in the formation of the tubular article, and hereinafter more F'gureS is a side view of the molded-and cut article produced by the die forming the subject matter of this invention.

The article which is produced bythis device is known in the macaroni industry as maltagliato, and is rather a demanded article, for it has, aside from its quaint appearance, certain other characteristics better known in the macaroni industry, which add to the tenacity of the article after it is cooked. V

Referring again to the aforesaid illustration 10 represents the lowerend of the cylinder of a macaroni press, which may be conveniently formed with a flange 11 extending inwardly and right angles to the walls of the cylinder.

On this flange 11 is accommodated, or set, the die 15 which is formed, as more clearly shown in Figure 5, with a shoulder 16. The construction heretofore described is old in the art, and no claim of novelty is made thereto.

The die 15 comprises a base die 17 and a cap member 18, the cap member 18 being substantially at secured to the base die 17 by means of bolts 7 19 passing through alined holes in the cap member and in the base die. The base die 17 is formed with a series of concentrically arranged holes 20 in which are arranged the cores 21, formed with prongs 22, through medium of which they are held in the holes, and with the shanks 23. The holes 20 are contracted, or made smaller in diameter, at 25 where the collar 26, on the shank 23 is located. The paste which. is pressed downwardlyv in the cylinder" is forced between the collar 26 and the walls 27 at the restricted portion 25 and it through which extend the shanks 23 of the cores 21. This cap member 18 is formed with a plurality of concentrically arranged inclined faces 35, to whichextend the holes 30. There being as many inclined faces as 7 there are series of concentric holes 30; In the illustrated example there appearing only 2 inclined faces, for th ere are 2' series ofholes 20and 30. The col'la 26, as it will be noted from the illustration in Figure 5 and in Figure 6, has a tapered portion 36 and a straight portion 37. The width of the straight portion 37 is substantially shorter than the length of the walls 27 of the contracted portion of the hole 20: By actual tests and experiments it has been found, that unless the lower edge 38 of the straight portion 37 extends to a distance shorter than the plane or the inner face 39 of the base die 17, the molded paste emerging from the hole 2O will clog and spoil the smoothness of the faces thereof. Special stress is laid on this course by the pin 40, and thus prevented from bulging or warping. v

From theheretofore description it is seen that the die of this invention comprises substantially a base die 17 and a cap member 18, the two being held together by means of the bolts 19, and both being formed with alined holes, through which extend the plugs 21, with the shanks extending to a plane coinciding with the inclined faces 35 of the cap member 18. It is understood that these two members 17 and 18 could be manufactured in one piece, and with any number of inclined faces 35, and a-ny number of holes 20 and 30'. The die is made in two pieces in order to simplify its construction.

In order to effectthe cutting of the molded tubular paste the hereinafter described device is resorted to. Beforedescribing this device it is necessary to briefly state that there are now in use'macaroni presses that I have revolving knives for cutting the molded tubular past at right angles to its axis as it comes out of the die. Such devices generally comprise a shaft 50, which by means of gears or pulleys is made to revolve below the cylinder ofthe press with its axis substantially in line with that of the cylinder. To this shaft is connected or coupled a knife which revolves with the shaft and which cuts at the outer face ofithe: die

th material molded as it emerges. An object of this invention is that of employing as far as possible the standard equipment now in existence, and for that reason the hereinafter described apparatus is employed in connection with the said shaft 50.

The cap member 18 is provided with a central hole 51 inwhich is madeto fit the end 52 of a sleeve 53. This sleev 53 is conveniently contracted at 55 and threaded at 54. The contracted portion 55 is surrounded by a revolving sleeve 56 and is held in its place by means of a threaded ring 60 which cooperates with the threads on sleeve 53. In order to eliminate as much friction as possible, an d'also in order to prevent looseness of the sleeve 56, l interpose between the revolving sleeve 56 and the threaded ring 60 a bearin ring 61, which may be conveniently made of metal or of some other substance better fitted for the purpose used. The remaining portion of the shaft 50 is enveloped by a tube which is provided at its lower end with a gear or a pulley for receiving its rotation movement.

In this case the shaftis held stationary and the tube 65 is made to rotate about the shaft. However, the shaft may be made to rotate if necessary. The means that rotate the sleeve 65 are not shown, for they'do not form a part of this invention.

On the sleeve 65:1 clamp, by means of a bolt 66 a clutch ring 67 which is preferably provided with an arm 68 having a hole 69. The arm 57 of the revolving sleeve 56 is provided with a clutch pin '20 which is either made to bear against one of the faces of the arm 68, or inserted in the hole 69. From this connection it is seen that the revolving movement of the tube 65 is transferred to th sleeve 56 which rotates on the sleeve 53, the sleeve 53 and the shaft 50 being held stationary, and employed as supporting mem bers for the revolving sleeve 56 and the tube 65. v

The arms 57 and 58 are provided with openings adjacent their outer ends in which are insert-ed the shanks of the knives or cutters and 76. The said shanks are firmly held in place by means of bolts 77, each. of which is threaded in a hole in the arms 57 and 58 respectively, substantially at right angles to the axes of the shanks '55 and 776 and against which they bear when tightened. 1n the illustrated example the knif at the end of the shank 75 co-operates with' the outer inclined face 35 of the cap member 18 and the knife at the end of shank 76 cooperates with the inner inclined faee 35 of the said cap member. In case there are. more inclined faces than the number" shown in the illustrated example then the sleeve 56 is provided. with as many arms as" there are inclined faces, each arm carrying a knife.

Reference is now had more specifically to .the invention, as defined in' Figure 3 wherein the knives or cutters 78 and 7 9 are illustrated as they appear looking toward the die. It will be noted that the blades of the cutters are disposed in a position in advance or forward'of the axes of the shanks and 76. This is done so as to effect the cutting of the molded article as it emerges from the die in a plane for ward of the axes of the shanks 75 and F6, for otherwise the point 80, for instance, of the shank 7 5' would interfere with the molded article before it was cut, if the knife was not arranged as described. The rotation of the knives is in the direction shown by the arrow A. The knives or cutters are curved adjacent their outer ends 81 so-as to begin the cutting of the article from a point slightly rearward of a line drawn between the center of the die and thecenter of the pin 40. This is done so as to prevent acrushing of the ends of the article to be cut, and to prevent any roughness that would take place at the lower portion of the cut end of the article produced.

The cutters in revolving about the inclined faces 35 of the die, cut themolded article as it comes out of the die, in lengths determined by the speed with which the article comes out of the die, and the speed of the knives or cutters. about the inclined faces. By changing either the speed of the knives or cutters, or the speed of the molded article in coming out of the die, the lengths of the maltagliato are varied.

This device will therefore eliminate the necessity of a cutting machine or of transferring from the press the molded article to such cutting machine. All that is necessary is a tray below the die and the. cutter in ,which drops the article as it is severed from the die.

I would state in conclusion that while the illustrated and described examples constitute a practical embodiment of my invent-ions I do; not limit myself strictly to the exact details herein illustrated, 'since, manifested, the same can be considerably varied without departure from the spiritof the appended claims:
