SALAIVII-TYING MACHINE.

Application iled February 18, 1922. Serial No. 537,579.

To all whom z't may concern.'

Be it known that we, BART F. Vrrronr and FRANK E. REDA, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Salami-Tying Machines; and we do hereby declare the following to bea full, clear, and exact description of the invention, such 'as will enable others skilled in `the art to which it appertains to make and use the same.

This invention relates to a machine for 4wrapping and tying a cord in continuous convolutions about a relatively solid object for the purpose of protecting and giving permanent shape thereto.

More articularly the invention relates to a machine for thus encasing salami or sausage and the objects of the invention are to provide a device of the character indicated of animproved and simplied structure adapted to feed the sausage or similar article in a smooth and compressed condition while the cord is wrapped and interlooped snugly thereabout as will hereinafter more particularly appear. y

The invention consists in the novel construction, arrangement and combinations of parts as hereinafter more particularly cle-- scribed and claimed.

Two sheets of drawings accompanying this specification as part thereof in which like reference characters indicate similar parts throughout.

Figure 1 is a vertical transverse section throughthe improved device showing the sausage in process of being wrapped in elevation.

Figure 2 is a mechanism.

Figure 3 is a vertical section through the cord spool and its housing.

Figure 4 is a detail view of the improved needle.

Figure 5 is an elevation partly in section taken from the left of Figure 1.

Figure 6 is a detailv view of the tying mechanism and Figures 7, 8 and 9 are detail views indicating steps in the operation of the tying needles.

ln accordance with the present invention a suitable base v9 is provided having secured to its upper face an annular ball-bearing support 8 adapted to support by means of plan view of the tension balls 10a second annular plate 7 secured to a vertically positioned tubular member 5. A gear 6 is also secured .to the tubular member 5 adapted to mesh with a worm 26 mounted upon shaft 24 which is adapted to be driven by any suitable means. A manually operable clutch 27 is associated with worm 26 for connecting or disconnecting said worm to shaft 24.y A suit-able housing 19 preferably encloses the mechanism thus far ,described and in turn supports a table 4 rigidly connected thereto in any suitable manner.

rlhe tubular member 5 is provided upon its outer face with a plurality of longitudinal grooves 11 arranged parallel and in spaced relation and each adapted to receive a needle 12. Each of the needles l2 is provided with an. outwardly directed lug 15 and a tubular housing 17 is supported upon the table 4 surroundlng tubular member 5, said housing 17 being provided upon its inner face with an annular guide groove 16 ada ted to receive and operate successively nee es 12 by means of lugs 15. An annular raceway connects the ends of guide groove 16, said race-way being preferably' or conveniently notched from the edge of housing member 17 and formed in association with gasket 18.

Adjacent the upper end of tubular member 5 is secured a pulley 20 having mounted on its upper face and adjacent its periphery a plurality of outwardly directed`- cam inembers 21.

A support 34 is secured to table 4 and pivotally mounted in support 34 is a shaft 37 provided with pulleys 39 and 38, the latter being connected by a belt with pulley 20 so that shaft 37 will be rotated by tubular meinber 5. r1`he support 34 is provided adjacent its upper end with lateral bearing members 35 and 36, adapted to rotatably support a tubular guide member 28 which may be conveniently formed with annular flanges` 32 and 33 to maintain it in proper relation to its supports. A pulley 31 is mounted u on the tubular uide .28 and connected by a elt with the pu ey 39. The pulleys 20-38 and 31-39 are similarly proportioned. so that the rotation of cylinder 5 will result in the similar rotation of guide cylinder28 and at the same speed. The uide cylinder 28 is provided with a plura ity of spring wire guide members 30, each attached by one end no i .to engage cams 21 carried by pulley 20. A

lateral arm 47 is slidably and adjustably mounted at one end as at 46 upon the slide rod 43, and a compression spring 48 is positioned between this member and the base block 42 tending to normally force slide bar 43 and roller 45 inwardly and toward cams 21. A stop lug 44 is provided upon the outer end ofslide bar 43 to limit its inward thrust., rlhe outer end of lateral arm 47 is provided with a spiral friction groove 51 adapted to receive and to operate as a slide brake upon the cord 6 as used. rlhe arm 47 alsol carries a transversely positioned wire bent into guide eyes 49 and 50, adapted to guide the cord to and away from the friction groove 51.

rl`he cord to be used is preferably provided as on spool 39 mounted in housing 41 upon the top of block 42 the housing 41 having an outlet mouth adapted to feed the cord through eye 49 around tension groove 51 and lthence through guide eye 50 to the needles 12 in tubular member 5.

A guide 25 is positioned horizontally above tubular member 5 and over the apex of the guide groove 16 to cooperate with needles 12 in holding the cord loop down during the elevation of the needle.

Each of the needles 12 is provided in addition to the outwardly directed lug 15 operator between the guide wires 30 in tubular guide member 28, said guide members tending to center the object relative to tubular gulde 28 and to rotate the same therewith at the same speed as tubular member 5. The cord with which the sausage is to be wrapped passes through spool 39 through guide 'eye 49 and around spiral groove 51 and thence through guide eye 50 and in regular loops over the hooks 13 of each of the needles 12. rllhe cord passes over the top of lide 52.

s cylinder 5\is rotated, a needle 12, immediately it passes under guide 52 begins to rise because -of the inclined portion of groove 16 with whichit engages. As it rises the loop caught under the hook 13 loop said loop turns the linger 14 upward closing hook 13 with the cord from the spool hooked therein and on further descent of the needle 12 into cylinder 5 the loop is forced over the top of needle 12, forming a stitch in the twine and a new loop. This stitch is repeated with each needle 12 in snc cession and continuously while the device is in operation. rlhe sausage descends with regularity by reason of its weight into and through the cylinder 5 while the stitches are thus formed, and the convolutions of the cord conforming to the shape of the sausage being contracted adjacent its upper end and thence expanded again over the lower end of the sausage next above as the same are continuously fed into the device by the operator forming a chain of sausages which depending below the machine can be removed as desired.

To permit the adjustment of' the tension upon the cord so that at the proper time it will be loose and at other times it will be tight, the reciprocating bar 43 carrying the cord guide eyes 49 and 50 and the spiral tension `groove 51 is employed. As cams 21 engage the roller 45 bar 43 is forced backward against the tension. of spring 48 and the twine is paid out but with enough resistance so that the convolutions of l cord will be tightly drawn about the salami. When the cylinder 5 has revolved suiciently. to disengage a cam 21, the bar 43 will spring forward bringing with it and toward cylinder 5 the extra cord previously paid out in time to supply the cord for the formation of the new loop under hook 13 at its uppermost position to be drawn downwardly by needle 12 and through the old loop so that the formation of the new loop will. not be impeded by dearth of cord nor the sausage distorted by an undue tightening of the cord at this stage of the operation.

@bviously the tension upon the cord can be modified by wrapping the same one or more convolntionsabout the spiral groove 51.

Having thus described our invention, we claim 1. 1n a machine for wrapping cord about.
