TllEdBVlC'E 1 am about to describe de signed to manufacture ravioli hutma as shove stated, he adapted to the ptwduction oi other stuhed alimentary erticlee. "he indicated in Fig. 1 paste oftheproper con sisteny is delivered to sets ofroliers and 8 from two hatches 1 and 2, which hetches in the first instance have been deposited on stationery tables 3 and d by the naachineoperator. in passing through these rollers the paste is formed into sheets 9, 10,'oi the correct thickness. While only two sets'ot calibrating rollers are here shown, heceuse two sets sufice in a narrow machineplwisli it understood that. more sets of rollers will he required in wide machines cepahle of producing long rows of ravioli at one time,

forms no part of the not herein shown. Centrally located, above the rollers 11, 12, 1s a suitable hopper 20, into which stufing material 21 is deposited. This hopper may be cylindrical in shape, or it may he oblong in a wider machine. It has no bottom but is provided with curved edges 20, 20 which edges are substantiallyconcentric with the rollers 11, i2. lhe edges are set so close to the periphery of said rollers, that the sheets of paste almost scrape against the edges in passing. 'lhe paste sheets may properly-he said to form the bottom of the hopper, and do form such bottom, as will presently appear;

The construction of the rollers 11, 12 is very important, because not only is each piece of ravioli formed between these rollers, but they are also separated and their edges pressed together in passing through the two rollers, as-will now he explained. Ravioli is made in difierent shapes. I prefer to shape the pieces as indicated in Figs. 2 and 3, in squares, be-

present invention it is cause they may be made in such shape without waste of material. Each square is provided with a studed center portion, and this center may he c'i rcular or square, as desired. it find the square mold most economical to manufacture, and the machine herein illustrsted. is provided with such square molds. Referring to Fig. 4 it is seen that the roller 11 is made with a seriesof rows of molds, 11 11*, there being in this case two molds in each row. The roller 12 is provided with periphferal, 'nnular cutters, 13 and 14;, and these cutters a e shaped to slit'the paste sheets length- "wise as they pass between the rollers. On the roller 11 is mounted transverse rows of cutters 15, 16. It is important to note that, when the machine is in operation, these axially disposed cutters pass between the peripheral utters of the roller 12'.

ill

In operation the pastesheets and the form ters in such a manner, that the twelve pieces the result that the paste sheet 9 is forced into the molds 11, 11 and the space thereby created is filled with the same stufiing which depressed the aste. The two rollers 11, 12 are adjustably xed so close together that the two sheets of paste are very firmly pressed together, and no more stufiin g is able to crowd between the sheets than that which has lodged in the cavities of the molds. The ,stuflin is a thick, plastic composition. It does not ow very readily. And as the sheets of paste touch the bottom edges of the hopper, there IS no danger of any stuffing working its way between the paste and sald edges.

For family use cans capable of holdlng twelve pieces of ravioli, and filled with sauce, are usually employed. The form rollers 1s shown provided with six rows of molds. there being two molds in each row. The ordinary can of this capacity is large enough to receive the two pieces of ravioli of each row. As a consequence enough pieces are formed at each revolution of the rollers 11, 12 to fill a can. The paste is diflicult to handle and can only be successfully manipulated at very slow speed. The rollers 11, 12 should not make more than five to ten revolutions per minute. As a consequence ample time is afforded the conveyor to move forward step by step as each can isfilled.

Even after the pieces of ravioli have been completely formed and separated 1t 1s diflicult to keep them from adhering to one of the rollers. A series of suitable scrapers, 60, may be applied to the roller 12, and they may successfully dislodge and keep this roller free i from adhering pieces or fragments, but on account of the molds 11 11 and the axial cutters 15, 16 such scrapers cannot readily be applied to the roller 11. In case the paste P used shows a tendency to stick to the rollers it is well to modify the proportions of the cutof ravioli for each can are not entirely separated, but remain tied together in a strip 17 two pieces wide and six long, by a very thin film of paste. The weight of the free portions of this strip will help to dislodge any unit of the strip showing a tendency to stick to the rollers. In order to attain this result the cutters 13 and 15 should project a trifle farther than the cutters 14 and 16. The difference is so slight that it cannot be brought out clearly in the drawings, but it is thought not difiicult to understand by anyone versed in the art, that the cutters 13 will trim the edges of the strip and the cutter 15 will cut ofi the strip at each revolution of the rollers. As the strip sinks into the can, and strikes bottom, the pieces will commence to fold into an accordion shape, see also the diagrammatic Fig. 6, "particularly if guidedbetween suitable gauges 22, 23. The subsequent cooking ii? the can and the later. handling of the cans suffice to separate the pieces that are not torn apart in falling into the cans.

Where the form rollers are twice the diameter there willbe twelve rows of molds, and two diametrically opposed cutters 15 would be required, in order to deliver twelve pieces of ravioli in each can. My aim is to point out that, given a certain capacity of production per minute, and a certain width of machine, there is a fixed relation between cutters and molds, even as the timing of the movement of the conveyor has a fixed relation to the rotation of the form rollers.

A referred construction of the roller 11 is in icated in Fi 5. The roller is shown made in five sections, and the sections are shown se arated on the roller shaft, for the sake of c earness. There are two outer sections 30, 31, which maybe exactly alike but assembled in reverse relation. Inside of these are two intermediate sections 32, 33, which also may be identical in sha e. In the center is a section 34, or two sectlons 31 may be assembled, the opposite way, an used as a center. The advantage of this construction is that, in making the roller, only simple turning and milling operations are emplgyfd, as against-the expensive 0 eration of si 'ng molds into the surface 0 a solid roller. Those versed in the art will readily appreciate, that the rollers 12 similarly may be made in four sections, of which the two end sections 12 and the two center sections- 12 may be respectively alike.

The cutters 13, 14, 15, 16 are preferably made crimped, as indicated in the drawings,

part1 because the appearance of the finished artic e is therebyimproved, and mainly for the reason that t e serrated edges of the comressed pieces of paste become looked very tightly together, and will not come apart.

The device ofm invention may be driven from any suitab e source of power, not shown, and such power is. applied to rotate a drive shaft 40 which, through suitable gearing, such as a chain 41, is connected to rotate the roller 12 at the speed hereinbefore indicated. Rigidly combined with the latter is a gear wheel 42, and this wheel drives an identical ar wheel 43, of the roller 11. From the r0 ler 12 extend chains 44, 39 to the roll.- ers 5 and 8, and the roller-11 is similarly operatively connected with the rollers 6 and 7 In this manner all the rollers are connected to be rotated continuousl at the proper speed. Chain gearing is s own for the sake of clearness and simplicity, but in actual practice I prefer to employ worm and spur gearing.

For the purpose of imparting properly timed intermittent movement to the conve or, an arm 45 may be fastened on the drive s aft 40. This arm is positioned to strike a pin 46 of a bell-crank 47 and the latter carries a spring-held pawl 48, which in turn engages a ratchet wheel 49, of the conveyor shaft 50. The bell-crank is, by a spring 51, normally held retracted a amst a suitable stop 52. As the arm 45 reac es the pin 46, it commences to swing the bell-crank and to turn the sprocket wheel, until a forward step of the conveyor has been effected,whereupon the arm passes the'pin, and the spring '51 is free to return the bell-crank to its normal position. A mechanism as.the one just described will advance the cans, as required, but I wish to state that, in practice, I employ much more elaborate devices in order to efiect a smooth, positive movement to the conveyor. But as the particular means employed does not form part of this invention, I have shown one which can be easily comprehend'ed by the reader.

Means, such as a weight 60, may be placed in the hopper in order to apply pressure on the stufling, sufiicient to force the latter into the molds 11, 11". More elaborate devices may be substituted but the simple weight 60 is, perhaps, the most convenient, on account of its very simplicity.

In lace of recessing on y one form roller the fu ll depth of the stufiing it is, of course, possible to sink the molds one-half the distance into each roller, as indicated in'Fig. 6, where the'rollers 70,, 71 are provided with shallow half-molds 7 0 and 71. The cutters 72, 73 may remain exactly the same as the cutters 15 and 16. One obJection'to this construction is the additional expense of the second set of molds, and little is'gained, un

less the appearance of the finished article is the main consideration.

I claim: j

1. In a ravioli machine, a cuttin roller comprising, a lurality of cylindrical sections and circn ar knives of a larger diameter between said sections; in combination with a second roller comprising, a series of cylindrical sections having convex annular beveled edges and a series of cylindrical discs fitting between said sections, the periphery of said discs having transverse grooves the edges of which are beveled to correspond with the annular convex bevels of the roller, and axial cutters seated between said grooves and fitting between the circular knives of the first named roller.

'2. In a ravioli machine a pair of intergeared rollers, means for formlng and feeding sheets of flour paste to said rollers, an

ing to the paste sheets on said rollers, t e bottom edge of said hopper being shaped to conform to the contour of the rollers, means on the rollers for cutting the stuffed paste sheetsf into s uares, one or both of said rollers bein provi ed with deep square molds into whic the stufied paste is free to enter, there being between said molds and the said. cutting means broad peripheral margins between which the paste sheets become rmly pressed together and the stufling expelled from these marginal portions.

3. In a ravioli machine, a pair of intergeared rollers provided with indented molds and having annular and axial cutters separating said molds, there remaining a substantween said molds, the other roller being made with annular per pheral cutters adapted tobe positioned between the molds. of the first named roller at the point of contact of the rollers, all the molds being s aced apart so as to provide a wide margin etween the Y cutters and the molds, means for feeding sheets of flour paste to the rollers, and a detachable open bottom hopper for guiding stalling to the paste sheets on the rollers.

5. In. a ravioli machine, a pair of intergeared rollers provided with indented molds and having annular and axial cutters between said molds, there being a substantial peripiseral margin between the cutters and mo means for feeding sheets of paste tothe rollers, an open bottom hopper with vertical sides above said rollers for iding stufiing to the paste sheets on the rol ers, and means for ad usting said hopper vertically to accommodate paste sheets of various thicknesses.

In testimony whereof I have hereunto affixed my signature.
