CARLO MERLI ANI) GIUSEPPE BERTOLINI, OF NEW YORK, N. Y.; SAID BERTOLINI ASSIGNOR OF HIS ENTIRE RIGHT TO VICTOR KLEINBERG, SALVATORE MANGIA- PANE, AND FRANK FUMO, ALL OF NEW YORK, N. Y.

KNITTING MACHINE.

Application filed February 8, 1921.

To @ZZ whom t may concern.'

Be it known that we,CARLo MERLI and GIU- snrrn BERTOLINI, citizens of Italy, residing at N ew York, in the count-y of New York and State of New York, have invented ner and useful Improvements in Knitting Machines, of which the following is a specication.

This invention relates to machines for tying articles and has for an object the pro- Yvision of a machine which is especially designed for tying or knitting a cord or the like around meats, previously stuffed within a skin or casing the machine being designed for use in connection with an improved stuffing machine for which an application has been iiled by us of even date herewith.

Another obj ect of the invention is the provision of a machine as above specied, in which the meat or other article is fed through a cylinder, the machine being operated during such feeding, so that the cord will be wrapped and looped about the article in a manner to provide a series of relatively tightly drawn interwoven convolutions and loops and thus maintain the article in an attractive and sanitary condition.

Another object is the provision of a knitting machine which includes a plurality of separate units, preferably of different sizes to accommodate different size articles, the said units being operated simultaneously or independently, the character of the article for which the machine is especially designed varying in size, so that the said articles may be graded and fed through their proper unit.

l,Vith the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illust-rated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1V is a side elevation of a knitting machine embodying the present invention.

Figure 2 is a top plan view of the same.

Figure 3 is a sectional view on the line 3-3 of Figure 1.

Figure 4 is a fragmentary end View of the Serial No. 443,454.

machine, the view being on an enlarged scale.

Figure 5 is a vertical sectional view through the subject matter of` Figure 4.

Figure 6 is a detail elevation of one of the revolving cylinders.

Figure 7 is an enlarged fragmentary view showing the manner in which the cord or thread is looped or interwoven about lthe article.

Figure 8 is an enlarged elevation of the cord container and cord tensioning device.

Figure 9 is a fragmentary plan view of the tensioning device. v

Referring in detaily to the drawings, wherein like characters of reference denote corresponding parts, the machine as illusrated includes a table l0, which may be supported in any suitable manner, as upon legs l1.

Rising from the top A12 of the table is a` plurality of vertically disposed rods or standards 13, which have their upper ends secured to a supporting plate 14, theflatter being provided with spaced openings 15. Positioned within each of the openings l5 is a cylinder 16, the latter being provided at its lower end with a reduced portion 17 anda shoulder 18, the former being receivedwithm the opening 15 of the table top, whilethe latter rests upon the upper face of the said top, so that the cylinder 16 is rotatably mounted within the opening 15.

As shownin the drawings a number of these cylinders are provided, the said cylinders varying in size, the purpose being to.v provide for tying articles of different sizes. This is essential in a machine used for the purpose for which the present machine is especially designed, that is, in tying certain cuts of meat previously stuffed within a skinl or casing, the said cuts not being of a uniform size.

Spaced above the supporting plate .14 by means of spacing rods 19 is a plurality of relatively small bearing plates 20, which are y provided with openings 21 for the reception sleeves also surrounding each of the cylinders 16. v

Operatively mounted in each of the cylin ders 16 is a plurality of knitting needles `23, the number of Vthese needles being regulated in accordance with the diameter or size of the cylinders 16. As shown in the drawings the number of these needles range from tour to seven, although this number mayl vary in accordance with the closeness which it is desired that the article be wrapped. ylhe needles 23 operate ,in longitudinally disposed slots 24 provided in the outer periphery of the cylinders 16, the said needles being of the usual type employed in connection with knitting machines, that is, they include a hook 25, a pivoted latch 26 and a butt 27, provided in the shank of the needle opposite the hook end. The stationary cam sleeve 22 is provided with a. cam slot 28 which receives the butt portions 27 of the needles so that when the cylinder 16 is rotated, ina. manner 4to be hereinafter described, these needles will be moved longitudinally or their guide slots 24.

For the purpose of rotating the cylinders 16, each or' said cylinders is provided with gear teeth 29, the teeth or each adjacent cylinder being engaged by a gear 3Q, which is mounted upon a stub shaft 31. The teeth of one of the cylinders 16 is engaged by a gear 32, which i's shown as carried by a vertically disposed shaft 33. This shaft also carries a beveled pinion 34 which is engaged by a pinion 35 carried byva shaft 36, upon which is mounted lfast and loose pulleys 37, by means of which power may be applied tothe machine. The shafts 33 and 36 are mounted in suitable bearings provided in a standard 38 rising from the table top 12. The gears 30 are loosely mounted upon the stub shafts 31 and when` these gears are in position, each of the cylinders 16 may be simultaneously rotated. However, if it is desired to cut out the operation oit some of the cylinders 16, certain of the gears 30 may beremov'ed from rthe shai'ts v31. The ma` vchine thus provides a plurality of separate port 41 extending from the container 40 and a spring t'arm 42,'the latterbeing provided with Ia cord receiving slot 43. Trhe cord passes fromfthe container downward` through ythis-slot between the spring plate 42 and the "support 41, tension being regulated by'means set screw The cord passes from the itefnsioning v`device l"to Ja 'guide `'ng'er 45 one of which is secured to each of the Stationary cam sleeves 22, the said ringer being arranged to properly position the cord for engagement by one ot the needles 23.

In the operation or the machine, power is applied to rotate the cylinders 16 and one end ,of the article is inserted within the top of one or more of the said cylinders. Rotation of these cylinders will cause the cord-,to .3e wrapped about the article in spiral iorn1ation, the needles on their downward move-` ment engaging` the cord within their hooks 25 and drawing the said cord downward within notches 46'provided in the upper edge of the cylinders 16. During this downward movement, the latches 26 of the needles will be closed bythe convolution et the cord imi mediately below the one in wliiclrthe loops have just been formed and will draw the cord through these loops in the manner illustrated in Figure 7 and provide a knitted or interwoven wrapping for the article. As soon as one article has been wrapped or tied, another may be fed immediately through the guide, so that a series oit connected articles inay be'provided as is also shown in Figure 7. The table top 12 is provided below each of the units with openings 47 and the articles may thus be continuously fed through the machine and afterward separated as cesired.

rlhe invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Havingv described the invention what is claimed is il knitting machine vembodying a table, a plurality oit horizontally arranged supportingplates spaced above the table and having openings therein, cylinders varying in diameter and having their lower ends mounted for rotation in said openings, needles operatively mounted about thc cylinders, a stau tionary sleeve surrounding each cylinder ane` having a cam groove therein, the walls oi which engage the needles, an annular iange extending around the bottom-of said sleeve,

and spaced rods connecting the plate and lsleeve flange for supporting the sleeve spaced about the cylinder supportingl plate, whereby said sleeves will provide a bearing for the cylinders, a gear train connecting the cylinders, lsaid train including gears sur! tures.
