bolted to the floor. Between the upper parts of said plates 2 2 extends a rear shaft 5, having fast upon itself saws 6,which are statione at suitable intervals to cut the macaroni into such lengths as may be desired. Said saws 6 To all whom it may concern.-

Be it known that I, SAMUEL MUELLER, a citizen of the United States, residing at Jersey City, in the county of Hudson and State have invented certain new 5 of New Jersey,

and useful Improvements in Macaroni-Saware each inclosed in a casing 7, which is open ing Machines; and I do hereby declare the at its front side, as at 8, to provide access to following to be a full, clear, and exact dethe macaroni an at the rear has a tubular scription of the invention, such as will enable extension 9, which is connected with any orothers skilled in the art to which it apperdinary style of blower (not shown) to draw tains to make and use the same, reference be or carry away the sawdust which arises from ing had to the accompanying drawings, and the cutting of the macaroni. Forward of the to numerals of reference marked thereon, rear shaft 5 is arranged a second shaft 10, which form a part of this specification. also having bearings at its ends in the said The objects of this invention are to proplates or frames 2 2. Upon this shaft close vide a machine for sawing macaroni into suitto one of the side plates 2 is arranged a transable lengths for packing, to thus enable the verse plate or stop 11, against which the ends strips of macaroni to be cut into lengths meof the macaroni to be sawed may abut to 'se chanically and with greater accuracy than cure their being even, said stop being located can be attained in cutting them by hand, to at a suitable distance from the saws 6. Said enable a large number of macaroni sticks to saws are preferably adjustable lengthwise of be cut at one time, to secure a rigid holding the shaft 5, so that the same machine can be of the macaroni during said cutting, to ob adjusted to out different lengths. The shaft tain a machine which shall perform the cut- 10, furthermore, carries at suitable points ting rapidly and with little attention upon circular series of radially-projecting arms 12, the part of the operator, to enable the cutting which are adapted to grasp and hold the bunto be done with less care and skill than handdle of macaroni being sawed. In the drawwork re uires, and thus reduce the labor and ings I have shown one circle of holding-arms cost, and to obtain other advantages and readjacent to the stop-plate 11 and two others, sults, some of which may be hereinafter reone on each side of tne first saw and a fourth ferred to in connection with the description i at the inner side of the second saw, the short of the working parts. ends which are severed by said second saw The invention consists in the improved being drawn away with the sawdust by the macaroni-sawing machine and in the arrangeblower. ments and combinations of parts of the same, Each of the holdingarms 12 comprises all substantially as will be hereinafter set halves 13 14, adapted to be bolted together, forth and finally embraced in the clauses of as at 15. (See Figs. 3 and 4 particularly.) the claim. Preferably a series of the arms 12 is arrange Referring to the accompanying drawings, around the shaft .10, so that a plurality of in whicn like reference-numbers indicate corbunches of macaroni may be inserted at each responding parts in each of the several figrevolution of the shaft 10. Obviously the ures, Figure 1 is a cross-sectional view of a number of arms thus employed in a series machine of my improved construction. Fig. will be limited only by the speed of rotation 2 is a front elevation of the same. Figs. 3 and the dexterity with which the operator and 4 are detailsin side elevation and plan, can insert the macaroni. I have shown in respectively, of one of the holding-arms; and the drawings four such arms 12 in a circular Fig. 5 illustrates the driving connections of series, and in this case the upper part 14 of the machine located at the end of the same. one arm is preferably cast in one piece with In said drawings, 2 2 indicate end frames the under part 13 of the next arm, so that all or plates of my improved machine, which the arms together completely encircle the bolted together clamp shaft and by being as shown in the drawthemselves thereon, ings.

are adapted to support between themselves the shafts and working parts hereinafter described, said end plates or frames 2 being held in relative parallel positions by means said plates 2 providing l wardly and forwardly concavely curved exbottorns feet 4 to stand upon or be at their I tension 16, upon which as the arm is brought The under part 13 of each arm has a down-' ITO upward by the revolution of the shaft the bundle of macaroni sticks is adapted to be laid. The upper member 14 has an oppositely-curved extension 17, which projects, however, only partially as far as the firstmentioned extension 16, so as to leave between the ends of said extensions 16 17 an opening 18, through which the sticks of macaroni may be inserted. The holdingarms 12, it will be understood, are sufficiently broad to form a suitable seat for the sticks of macaroni.

To close the opening 18 of a holding-arm and to bind the macaroni in place while being sawed, I have provided upon the extremity of the upper arm extension 17 a hinged gate 19, which is adapted to close across the opening 18, passing at its extremity along the inner surface of the extension 16 of the under member 13 of the arm and closely adjacent thereto. This gate can close inward macaroni and thus it adapts itself to any size of bundle, always grasping in an equally effective manner. means for automatically opening the gate 19 as the arm comes into position to receive the macaroni and for again closing the same tightly against the sticks as they pass away from the operator to the saw. For this purpose I have shown in the drawings a leverarm 21, pivoted upon the base of the said gate 19, as at 22. The inner end of this lever-arm forms a V-shaped lug 24, engaging the back of the gate 19 when said gate is open I and preventing the lever-arm 21 from being forced back by the power of springs 26 23 into another than perpendicular relation to said gate. (1 spring 23, being bent around the pivot-pin 22, is fastened to leverarm 21 at one end, at the opposite end engaging the outer extremity of the gate 19. A spiral spring 26 extends from the said leverarm 21 to some part of the mechanism which is fixed with reference to the holding-arm as a whole, preferably the body portion of the next holding-arm, as shown in the drawings. The effect of this spiral spring 26 is therefore the opening of the gate 19, and between which is pivoted the lever-arm 21. As will be understood, and furthermore, a detent leaf-spring 28 may be provided upon the arm member 14orits extension and curved at its extremity 29 to snap over a shoulder 30 of the gate 19. For forcing said gate 19 shut after the macaroni has been inserted a roller 31 is held in position to engage the outer end of the gate 19 as the same projects out, tending to close said gate and throwing the outer end of the leverarm 21 upward between said roller 31 and the end 33 of a curved track 34, which extends .saws or at the lower part of the until it strikes the bundle of Furthermore, I provide around the inner or concave face of the semi circular guide which lies in the same plane and in the path of the holding-arms. Said curved track forms a ca having an enlarged upper extremity 3 with a convex The extremity of the lever-arm 21 is armed with an antifriction-roll, which traveling upon the convex surface forming the entering portion of track 34 forces. the arm back and closes the gate 19, as shown particularly in Fig. 1, and, furthermore, it will force through the spring 23 the macaroni into a compact mass, the spring, however, taking up excess pressure, so that the stock will not be crushed or broken. Holding the macaroni as thus described, the arms carry it against the saws 6, and after leaving said rotation said arms discharge the sawed macaroni, as will be next described.

- A box or tray 35 is set beneath the arms and the track 34 is terminated at such a point that as the lever-arm 21 runs off said track the spiral spring 26 throws the gate 19 wide open, when one length of the macaroni will drop in the said box or tray 35. It will be understood that since the adjacent bun-- dles of macaroni are separated by only a sawslit the box or trays for the different lengths cannot be arranged in line, but must be staggered, and I therefore terminate the tracks at different points, so that each bunch of macaroni will be dropped into its appropriate box. r

For driving the mechanism described I have shown in the drawings belt-pulleys 37 upon the saw-shaft 5 and a short end shaft 36', which transmits motion from said saw shaft 5 by means of a worm-and-ge'a'r connection to the forward shaft 10, A clutch 38 is preferably employed upon this last or holding-arm shaft 10,.so that the feeding of macaroni to the saws is under the immediate control of the operator. 7 I

Having thus described the invention, what I claim as new is 1. In a macaroni-cutting machine, the combination of parallel shafts, saws mounted on one of said shafts, a longitudinal series of the opposite side walls, a track adapted to engage the outer portion of said gate and close the same against the power of said spring, and a roller adapted to be engaged by the inner portion of the gate before said track is reached to throw the outer portion into position to engage said track. g

2. In a macaroni -sawing machine,'the' combination with a saw, of a holding-arm having an inwardly concave curved extension and a shorter similarly-curved eXtension opposite the first, a gate pivoted upon said shorter arm whose extremity is adapted to describe the curve of the inner surface of the opposite extension, a lever-arm pivoted on said gate, a spring normally holding said lever-arm away from the gate, a track adapted to engage the outer portion of said gate and close the same against the power of said spring, and a roller adapted to be engaged by the inner portion of the gate before said track is reached to throw the outer portion into position to engage said track, and a spring normally holding the gate open, and means for moving the holding-arms with respect to the saw.

3. In a macaroni-sawing machine, a saw,

lever-arm and the pivoted arm and more yielding than the macaroni, and a track concentric of the shaft to engage the lever-arm of the pivoted arm, to close the holding-arms during part of the rotation.

In testimony that I claim the foregoing I have hereunto set my hand this 30th day of 30 December, 1904.
