18 Claims. (Cl. 107-21) This invention relates to improvements in handling machines for spaghetti and like products.

Spaghetti is conventionally hung in looped, vertically extending elongated strips on carrying rods supported on elevated drying racks, and objects of this invention are: (l) to transfer these elongated strips of spaghetti (which has usually heretofore been done by hand) to a flatly supported position on an operating table; (2) to relieve such elongated looped strips of their carrying rods; (3) to gather said elongated transferred strips of spaghetti in a sweeping operation into a cutting trough, and (4) to bundle, hold and out said elongated strips of spaghetti into a plurality of shorter pieces or box lengths by aligning, bundling, holding and cutting operations, said holding and cutting operations being successively accomplished to compensate for knife thickness and to avoid distortion and breakage and producing equal box lengths and removing the looped end loop portions.

To carry out the first object of this invention I provide novel means for handling and transferring the carrying rods with their loads of looped spaghetti strips (which rods are usually arranged on horizontally disposed racks in elevated position, each rod having its load comprising a series of looped strips of spaghetti hanging in a vertical position therefrom), to a supporting table and thence to cutting knives. For this purpose, the loaded rods are initially transferred to an overhead horizontally-disposed feeding rack and preferably moved forwardly with the spaghetti in such vertical position to the terminal or feeding end thereof where such loaded rods are fed to a pair of swinging transfer arms (adapted to automatically en gage the ends of such rods by rod-engaging and carrying elements at the upper ends of said pair of transfer arms in erect position thereof) and in one continuous movement which is divided into (1) a loaded-rod-transfer movement to lay the rod and load in supported fiat position on a strip-gathering table, (2) a rod-releasing movement, and (3) an erecting load-receiving movement, the load of strips of spaghetti carried by said rods are arranged or laid in flat position on a gathering table and are freed from their carrying rods.

Another object of my invention is to carry out said three movements by providing transfer arms each of which is formed of two parts, one comprising a pivoted powerapplying base member having a simple rotary movement about a fixed axis and the other a propelled rod-engaging transfer arm pivotally mounted intermediate its ends on the outer end of said pivoted base member, said base member and arm both having a conjoint forward pivotal movement in an arcuate path to a position at or adjacent to the end of the outward progression of the rotary path of the base member to carry and transfer the loaded rods preferably across strip-guiding means and into contact with said strip-gathering table in a spaghetti-supported position, then during a rearward receding movement of said pivoted base member, the propelled transfer arm is moved thereby to cause the same first to move in a guided movement transversely across said table in a retractive movement parallel with the spaghetti strips thereon to release the drying rods from the strands of said looped spaghetti strips, and secondly to move upwardly during an additional retractive movement to release and deliver the rod to a Slide extending to the rear of the machine. Thereafter during a further rearward movement of said power-applying base member said transfer arms are moved into erected rod-engaging position, while the transferred spaghetti strips are by additional manipulation of such strips gathered into a cutting trough, cut by knives and finally delivered to a packaging container.

To carry out the second object of my invention, I provide novel mechanism for moving a sweeping paddle longitudinally along said gathering table and transversely of the strips supported thereon comprising a paddle-carrying carriage mounted to move on a pair of spaced rails at the front of the strip-gathering table and provided with a vertically-movable slide operable by a continuously movable sprocket chain mounted on sprockets and adapted to operate pivoted lever mechanism to lower a paddle into sweeping or spaghetti-gathering position at one end of said chain and to raise said paddle into inoperative position at the opposite end thereof, and thus to sweep a rod-load of such spaghetti strips into a holding and cutting trough.

To carry out the third object of my invention, I provide novel mechanism preferably comprising a strip-aligning element, an initial strip-gathering and holding member and a plurality of knife-blades, each having holding elements at opposite sides of the blade, and being movable successively into spaghetti-cutting operation whereby I am enabled to successively cut into a plurality of packaging lengths the strips of spaghetti which havebeen swept, as aforesaid, into said holding and cutting trough, and I also preferably provide means suitably synchronized with the movement of the knives for lowering the trough bottorn to deliver the cut spaghetti into suitable containers.

With these and other objects in view, the invention comprises the combination of members and arrangement of parts so combined as to co-act and cooperate with each other, in the performance of the functions and the accomplishment of the results herein contemplated, and comprises in one of its adaptations the species or preferred form illustrated in the accompanying drawings, in which: Fig. 1 is a view in side elevation of a spaghetti handling machine embodying my invention;

Referring now to these drawings which illustrate a preferred embodiment of my invention, 1 indicates a movable rod-carrying vehicle or case having rollers.2 and adapted to be filled with rods 3 having strips of spaghetti 4 looped about and hung in vertical position from the same. The case 1 is provided with oppositely disposed cross bars 100 and 101, having notches such as 102 and 103 for supporting the terminal ends such as 104 and 'provided for driving the conveyor chains.

of chains fi -are fixed to a shaft 8 4 105 of the rods 3. The rods 3 and looped bundles 4 of spaghetti are transferred from the vehicle 1 onto a drying rack 5 which is provided with rollers 116 and 117 mounted on rails 118 and 119 secured to the floor adapted to be lowered and then raised into engagement with the carrying rods for said strips of spaghetti. The rack 5 includes a pair of upstanding posts 106 and 107 together with suitable threaded spindles 108 and 109, beveled gears 110 and 111, a connecting shaft 112 and a handle 113 whereby

slideable'brackets

114 and 115 may be raised and lowered in a well known manner. Rack 5 may be moved forwardly or rearwardly on wheels such as 116 and 117 guided on rails such as 118 and 119. A conveyor in the form of a pair of

parallel chains

120 and 121 each having V shaped pockets such as 122 are mounted on the

brackets

114 and 115 and a hand crank 123 (see Fig. 2) with a suitable sprocket 124 is The handle 113 is rotatably mounted on post 107 and carries a bevel gear meshing with a bevel gear on the lower end of threaded spindle 109. Each spindle such as 109 or 108 is rotatable in a guide bracket such as 250 on its supporting .post such as 107 and is threaded in a block such as 251 on its slideable sleeve such as 252 which in turn supports

bracket

115 or 114. Cross shaft 112 carries bevel gears at each opposite end for causing duplicate rotation of threaded spindles 108 and 109 on each side of rack 5. Pillow blocks254 and 255 are secured to the upper ends of posts 106 and 107. Thus turning handle 113 rotates spindle 109, cross shaft 112 and spindle 108, thereby moving in a vertical plane the

sleeves

252 and 256,

brackets

114 and 115 and

chains

120 and 121. Rods 3 maythus be lifted off case 1 and advanced into rack 6 by turning handle 123-which advances the chains 120 and In accordance with the preferred form of my invention, the carrying rods 3 with their loads of spaghetti 4 are again transferred by a raising and lowering movement of the conveyor of rack 5 to an intermittently moved rod-feeding rack 6, the movement of which is suitably synchronized with the movement of transferarms 7 hereinafter more particularly specified. Rack 6 includes

upstanding posts

125 and 126 provided with

elongated supports

127 and 128, the supports carrying sprockets such as 129 (see Fig. 6) at each opposite end around which a pair of parallel conveyor chains such as 6' are trained. V-shaped pockets 6', similar to pockets 122 are spaced along chains 6 to receive the

ends

104 and 105 of rods'3 from rack Sand carry the same to the terminal-endo ofrack 6 where the adjacent sprockets 129 Supports. 127 and 128 are rigidly mounted in any convenient manner by welding near the top of posts 125m 126. Sprockets 129 are rotatably mounted on suitable stub shafts at each opposite end of the

supports

127 and 128. The terminal end 6 of said rack 6 is provided with a rod feeding gear 8 mounted on each stub shaft 8 and meshing with a gear 8 on another shaft 8. One of said gears 8 .isvprovided witha dog 9 pivotally mounted on a framemember 9 and movable into engagement with the -teeth of the gear '8 by link 10 whch is pivotal'ly coni nectedat oneend with said dogand also pivotally mountedat its opposite end on alever 11, which is pivotally .mounted-at one end on the shaft 8 and is pivotally con- ,ment oft-he shaft 7 to move the transfer arm 7 the cam-.12 will be rotated to engage a roller on a cam lever connected to, the rod 12 which will rock the lever 12, 1'2 on the shaft 12, thus depressing the rod 12 whereupon the'chains 6 of the rack 6 will be moved to cause engagement of the rods by contact with the engaging member 14 of each transfer arm 7, this mechanism being adapted to feed a rod with its load of spaghetti into registration with the said engaging members 14 of the arms 7-7 when the same are moved rearwardly into engagement with one of the rods 3 mounted at the terminal end of said rack 6.

In the preferred embodiment of my invention, the cam 12 for rocking the feed-

control lever

12, 12 is pro vided with four identical projections, whereby upon one rotary movement of the shaft 7 to swing the transfer arm, said link 12 and

lever

12, 12 will be moved four times and consequently the movement of the members 9, 1t) and 11 will produce a steady slow and gradual movement of the feed chains, and will thus prevent any excessive swinging or swaying movement of the spaghetti strips on the bars 3 which would occur if but a single cam was used on the operating shaft. Obviously by positioning the cam 12 on the operating shaft 7 the feed of the bars will be accurately synchronized with the movement of the arm 7.

Each of the arms 7 is provided at its outer end 7- with a releasable engaging element 14. Each engaging element 14 is preferably pivotally and resiliently mounted at one side of said outer end 7 to move beneath the outer ends of the rod 3 during the upward guided movement of said outer ends 7. Each element 14 is pivotally mounted on a pin 270 in a pivot pin recess in its arm 7 and includes another pin 272 which engages a leaf spring 273 on the arm 7. Each element 14 is thus normally held in an inclined position on its pivotal connection to arm 7 by its leaf spring. The spring is flexed by impact of roller 14 on table 15 and during the passage of roller 14 over the table 15. Each outer end 7 is also provided with a bevelled guiding pulley 7 which upon upward movement of said upper end cooperatively engages channel members or ways 215 to guide element 14 on said outer end 7 vertically into engagement with one of the rods 3 which has been moved in the notch members 6' of the chains 6* into the position shown in dotted lines at the outer end of the rack 6, it being understood that such rod 3 will, upon engagement and during the upward movement of the arms 7 above the position of the same on the rack 6, slide downwardly on the inclined bottoms or ways 14 to the position shown in Fig. 6, whereupon both arms 7 will be moved conjointly with a power-applying base member 7 into the position shown in dotted lines in Figs. 5 and 6 with the nose of each member 14, which is preferably provided with a roller 14 in contact with the upper surface of the sweep ing table 15. Said table, as shown, is positioned at or adjacent to the end of the outward progression of the rotary path of the base member 7 which is movable in a given circle and is pivoted on shaft 7 The transfer arm 7 thus embodies said pivoted power-applying base member 7 pivoted, as aforesaid, on the shaft 7 and movable about a fixed axis and the rod-engaging member 7 which is pivoted intermediate its ends on the stub shaft 7 supported in a bearing 7 at the upper end 7 of the base member 7.

The propelled rod-engaging transfer member 7' thus has a conjoint movement with the pivoted power-applying base member 7 in an arcuate path to the end of the outward progression of the circular movement of the said base member 7 at which position the member 14 will engage the upper surface 15' of the table 15 and at this point in said conjoint movement the lower end of the arm 7 will be released from engagement with the base member 7 by disengagement of a spring-pressed dog 16 carried by said base member 7 (see Fig. 4) from a socket 16 in the arm 7'. Each dog 16 is released by engagement of a roller 17 at the end thereof with a track 18 suitably arranged on a stationary bearing for the shaft 7 in the path of conjoint movement of the arms 7 and 7'.

As best shown in Fig. 6 a cross rod 360, carried by a pair of opposite brackets such as 361 retards the lower ends of the spaghetti strands 4 during their downward movement onto table 15.

Upon release of the lower end of the arm 7 from the power-applying base member 7 it will still be pivoted intermediate its ends on the base member 7 which, during its recessive movement, will exert a pull on its outer end 7 through said intermediate pivotal mounting 7. The recessive portion of the circular movement of the base member 7 will thus result in the pulling of the outer end 7 of the rod-engaging member 7' along the surface of the table 15 in a rearward direction parallel with the strands of spaghetti which have been laid upon said table. The member 7' will thus carry the rod 3 rearwardly out of engagement with the strands of spaghetti.

Upon reaching the end of the strands of spaghetti on the table 15 the intermediately-pivoted arms: 7 are swung about their pivots or shafts 7 to cause their heads 7 to move upwardly. This is accomplished by engagement of rollers 7 mounted at the lower ends of said arms with track members 19 positioned on the frame of the machine in the path of movement of such lower end. These track members 19 will, in combination with the circular movement of the power-applying base member, cause the rollers 7 on each of the upper ends of arm 7 to be engaged in ways 215 (see Fig. 5), and, at the beginning of upward movement through the ways 215, the engaging member 14, which is provided with a dropbottom 14 pivoted at 14 (see Fig. 5B) is normally held in closed position by a spring-pressed trip lever 20 extending upwardly from pivot 14. The lever 20 is, as shown, normally pressed into bottom-closing position by the spring 21, and upon engagement of said lever with the trip-track 22 the spring 21 will be stretched to cause the drop-bottom 14 to open and to release the empty rod then being carried in the rod-engaging member 14. This empty rod will then drop by gravity upon inclined rod-slides 23 on which slides said rods will roll by gravity to the rear of the machine (see particularly Figs. 1, 4

. and 5, 5A and 5B).

After the opening of the bottom 14 to drop the rods, the upper end of the arm is guided by the roller 7 and moved by the base member to a position above the triptrack at the upper end of the ways 215, in which position the spring-pressed lever will be released to close the dropbottom and the rod-engaging member 14 at the upper end of the member 7 will be moved into engagement with another spaghetti loaded rod.

The rod-load of spaghetti having been thus laid on the gathering table 15, means is provided for gathering said elongated transferred strips of spaghetti in a sweeping operation into a cutting trough 38 hereinafter more particularly described and for this purpose, I provide a sweeping paddle 24 and means for moving the same longitudinally along said gathering table 15 in a path transversely of the spaghetti strips supported thereon. As illustrated (see particularly Figs. 1 and 13) the paddle 24 is mounted at the outer end of a paddle carrying lever 24, which is pivoted on a spindle 25 carried in a carriage 26 mounted by

rollers

27, 27, 27 on. and movable along a pair of spaced

rails

28,, 28 positioned at the front of the strip-gathering table. The carriage 26is propelled along the edge of the table by connection thereof to a sprocket chain 29 mounted at its opposite ends on

sprockets

30, 30. Said chain and sprockets are not only utilized as a propelling mechanism but also provide means for initially holding the paddle in elevated position at one end of the table then lowering the paddle to sweeping position, and after completion of said sweeping movement, raising the paddle again into elevated position and propelling to initial position. For this purpose, the carriage 26 is provided with vertical ways 31 in which is mounted a slide element'32 which is connected to the lower transversely bent end 32 of the link lever 32, and which lower end 32, as shown in Fig. 14, extends into and engages the slide block 32 The upper transversely bent end of lever 32 is connected by a power-applying lever 24 fixed on the shaft 25 and adapted when moved by the link lever 32 to rock In the emthereof a roller 29 adapted during movement about the

sprockets

30,30 to move in the ways 31 from upper to lower positions and to carry the block 32 and the end 32 of the link lever up and down in the ways 31. No

,direct eonnectionbetween roller 29 and block 32 is necessary since the weight of the paddle 24 tends to liftt-he block 32in ways 31 and the roller need only push the block, 32 downward to raise the paddle 24 on its return, passage.

The roller. 29 .thusengages the block'32 and moves :..the same :withthe end 32 of the link 32 downwardly at one end ofv the; chain to cause an upward movement of the lever 24* and paddle 24 and upwardly at the other end of thesprocket chain, to cause a downward movement of .the paddle prior to a reciprocating back and forth movementof. said carriage by engagement of the roller. member with one side or the other of the ways 31.

:The roller 29* being thus connected with the slide block causes. said block. to move upwardly and downwardly when moved around the sprockets as hereinabove men- ..tioned and when movedalong the chain also traverses the same in a gathering movement while the paddle 24 is in lowered. position and traverses the same in the opposite .direction while the paddle 24 is in raised position.

The chain 29 is traversed by sprocket 30 which is fixed on the shaft 30 (see Fig. 13) mounted in ballbearings 30 and supported in bearing member 30 and rotatedthrough' bevel gear 30 which meshes with bevel ngear. 33 fixed. .on shaft 33 which is rotated (see Fig. 2)

by fixed bevel. gear 33 meshing with bevel gear 34 on transmission shaft 34, which in turn is rotated through gear 34 (see Fig. 1) from gear 35 on the main shaft 7 which is rotatedthrough gear 35 meshing with gear '35 on shaft 36 which is driven by pulley 37 from any suitable source of power, not shown.

Thestrands ofspaghetti .laid on table 15 are by the paddle 24 swept laterally or transversely into a cutting .trough 38 (see Figs. 3 and 7) located at one end of said table 15 and having an arcuate drop-bottom 38 pivoted on a pivot member. 38* (see Figs. 9-12) and operable into open position by gravity. Said drop-bottom 38 is movable into and normally held in closed position by engagementwith roller 39 (see Figs. 16 and 17) on the lever39 which is fixedly pivoted at 39* on beam 39" and movable by engagement intermediate its ends with arm 40 pivoted thereto at 40 and operated into closed and open position byengagernent of roller 40* at the opposite end thereof with cam 40 on shaft 34 (see Figs.

3, 16' and 17). Asrshown in Fig. 3 the parti-circular face of cam 40 holds drop-bottom 38 normallyclosed. synchronization with shaft 34, .the recess in the cam face rotates into position to allow gravity to momentarily "open the bottom 38*- to discharge the contents. of trough 38.

The various strands of spaghetti, upon reaching the trough 38 aremoved into alignment with each otherand for this purpose I provide at the inner end of the trough -38 a terminalend-and aligning flange 4.1 of segmental shapeso as to fit the end of the trough 38. Said flange .41 is fixedly mounted at the ends of a pair of reeipro- I eating rods 41 .41 which, as shown, are normally the-springs 41 intothe-said position shown in dotted lines-by cam-'41 carried on the outer face of flange. 41

e to engage the endsof the. spaghetti strands and .to move:

such ends into alignment with each other within the trough 38. The aforesaid aligning movement is synchronized with the movement of a pair of cutting

shafts

42 and 43 which are rocked successively to move cutting blades successively into cutting engagement by the earns 58, 58 as hereinafter described. Thus, on the shaft 42 I mount in a rotatively advanced position an initial gathering arm 44 which, as shown in Figs. 10 and 19, is

positioned adjacent to the inner end of the trough and is utilized for the purpose of engaging and gathering into a bundle the strands of spaghetti located within the trough 38. Arm 44 includes a slot for a pin on shaft 42 (Fig. 19) and is connected to the pin by a spring. Thus the arm 44 gathers the strands and then halts while the shaft 42 continues turning. On the same shaft 42 with said initial gathering arm 44, but spaced a suitable distance therefrom, I provide a knife blade 45 and also adjacent thereto and at opposite sides thereof, I preferably position resiliently mounted strip-retaining

arms

46 and 47. 'The

arms

46 and 47 are resiliently connected by springs 46 47 with the rear edge of theblade 45 and are positioned rotatively in advance thereof so as to move down before the knife blade 45 and to hold the strands of spaghetti in a gathered tightened position against the rear board 48 in order to enable the knife 45 which follows

such arms

46 and 47 closely to sever the strands upon a complete cutting movement of said knife blade 45 against the board 48, which is thus used as a cutting base member. The cutting movement of the

knife blades

45 and 50 will, as illustrated in Figs. 9

vto 12, sever from the spaghetti strips a given length such as shown at 49 in Fig. 12.

Severing of the strips by the knife will leave strip portions having attached loops at the uncut ends, and it will be understood that it is necessary to cut off such looped tips of the strands in order to provide an addi tional box-length. For this purpose, I provide a knife blade 50 with a pair of resiliently mounted strip-retaining

arms

51 and 52 similarly connected with the blade 50 by

springs

51, 52 and this knife blade 50 is adapted, upon a rocking and cutting operation as shown in Figs. 10 and 11 to sever the looped ends 53 from the intermediate portions 54' as illustrated in Fig. 12.

It will be understood that the knife 45 will have a certain thickness and in view of this fact, an operation of both knives together would cause a rupture of the spaghetti strands, and, in order to solve this problem, I have mounted the knife 50 and the resiliently mounted retaining

arms

51 and 52 on the shaft 43 which is separate from the shaft 42 and is independently successively rocked in relation to the blade 45, the movement of these blades, of course, being properly synchronized with the other moving parts of the machine.

In the embodiment shown, the shaft 43 (see Figs. 12 and 19) extends axially within the hollow shaft 42 and (Figs. 1819) is rocked by gear 54 and segment 54 on a cam-actuated arm 56 mounted on the inner protruding end of shaft 43 fixed to segment 54a while the hollow shaft 42 is rocked by gear 55 and segment 55a on cam-actuated arm 56. Segment 55 is carried by a sleeve mounted in a fixed bearing (Fig. 19). These

arms

56, 56 are connected with

rods

57, 57 operated by earns 58, 58 (see Fig. 2). As shown in Fig. 19 the cam actuated arm 56 is adapted to engage the curved cam track on the arcuate cam 41 carried by flange 41 and thereby force the flange 41 inwardly of the trough to align the spaghetti ends simultaneous with the descent of arm 44.

57 and 57 are yieldingly and resiliently heldagainst their respective earns 58 and 58 by springs .not shown.

By suitably arranging the cams, rods and segments,

the gears 54-55 may be successively rocked tomove the blades into cutting engagement with the strands of spa- .ghetti.

1 From the above, it will be seen that I am enabled first to align the strips, then to gather the spaghetti strips within the trough into an initial bundle before severing the same, then by successive movement of the blades to sever the same into two box-lengths and a joint or loop portion.
