3 Claims.

This invention relates to carding machines, and more particularly for providing a device in the form of an attachment to be used in association with a calendar roll or calendar mechanism for parallelizing the fibers in a card sliver.

An object of this invention is to provide an attachment for parallelizing the fibers in a card sliver which may be mounted on the present structure of a carding machine and may if desired, be positioned either on the input or the output side of the calendar roll, between the doffer cylinder and the calendar roll, between the calendar roll and the coiler mechanism, within the coiler head, or at any point from where the card web leaves the doffer up to the point where the card web or sliver enters the receiving can.

Another object of this invention is to provide an attachment of this kind which when mounted on the carding machine will eliminate the subsequent processing of the sliver through a drawing frame.

A still further object of this invention is to provide an attachment of this kind which includes pairs of rolls, a slidable mounting for the rolls and a weight connected to certain of the rolls for placing the sliver under the desired pressure as it passes through the rolls.

To the foregoing objects and to others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically referred to and illustrated in the accompanying drawings, wherein is shown an embodiment of this invention, but it is tobe understood that changes, modifications and variations may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

a Figure 1 is a top plan of an attachment constructed according to an embodiment of this invention, the attachment being shown mounted on a carding machine which is shown in fragmentary form,

Figure 2 is a sectional view partly in detail taken on the line 2-2 of Figure 1,

Figure 3 is a fragmentary end elevation of the attachment,

Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure 1, and

Figure'5 is a fragmentary sectional view taken on the line 5-5 of Figure 1.

Referring to the drawings, the numeral l0 designates generally the frame of a carding machine wherein a pair of calendar rolls II are rotatably mounted. The rolls H are mounted on shafts l2 and it which are journall ed in the frame structure It! and the shaft I2 is preferably extended laterally and is provided with a gear M which is fixed thereon. The gear 14 meshes with a gear I5 mounted on a shaft I6 which may be connected to a suitable driving means or other part of the card machine and whereby the desired rotary movement is provided for the calendar rolls II.

In order to provide a means whereby the sliver of cotton passing between the calendar rolls ll may have the fibers thereof made parallel, I have provided a parallelizin attachment including a pair of substantially U-shaped brackets generally designated at E1. The brackets ll have one leg l8 thereof disposed in a horizontal position for engaging on a horizontal frame part I9 which is formed as part of the frame structure Ill. The leg I8 is secured to the supporting part l9 by fastening devices 29. In the present instance, the bight 2| of the bracket I1 is disposed adjacent the lower calendar roll II and the upper leg 22 extends real'wardly and in parallel relation with the lower leg 18. The two brackets ll are positioned in the present instance, between the calendar rolls l l and the doifer cylinder.

Each upper leg 22 has a pair of guide members 23 and 24 for bearings mounted thereon. The guide member 23 is provided with a slot or recess 25 opening through the upper end thereof and upper and lower bearing members 26 and 21 respectively are slidable in the slot 25 which forms a guide for the bearing members 23. The guide member 24 is also provided with a guide slot 28 and upper and lower bearing members 29 and 30 are slidable in the guide-way 28. The guide members 23 and 2 1 may be secured to the upper side of the horizontal leg 22 in any suitable manner. An upper roll 3! is disposed between the two bearing members 23 and is provided at the opposite ends thereof with trunnions or stub shafts 32 which are journalled in the bearing members 26. A second upper roll 33 is dis posed forwardly of the first roll 3| and is provided at the opposite ends thereof with trunnions 34 which are journalled in the bearings 29.

A lower forward roll 35 which is provided at one end with a trunnion 3!: is positioned below the forward roll 3| and the trunnion 36 is journalled in one bearing 21. A shaft 3'! is formed with the roll 35 and extends from the roll 35 opposite from the trunnion 36. A gear 38 is fixed to the shaft 3'! and is adapted to mesh with a gear 39 which is mounted on a stub shaft 40 carried by the frame structure H). A second or forward roll ti is disposed below the roll 33 and is provided with a stub shaft or trunnion d2 journalled in one of the bearings 3 A drive shaft G3 is carried by the opposite end of the lower roll li and the drive shaft 53 has a gear M fixed thereto which meshes with the gear 35 A second gear :25 is mounted on the drive shaft Q3 and meshes with a gear 36 carried by a stub shaft ll. The gear 43 also meshes with the gear l lso that rotation of the calendar rolls M will effect rotation of the paralleling rolls 3t, 33, 35 and ii. The gear Gd is substantially smaller in diameter than the gear so that the two forward rolls 3! and 35 are rotated at a speed less than the rolls 33 and ii. In this manner there will be a drawing of the fibers which will effect a parallelizing of the fibers prior to the time the sliver enters between the calendar rolls l l.

In order to provide a means whereby the upper or idler rolls 3! and 33 may be held in contacting relation with the sliver and so that the desired pressure may be applied to the sliver, I have provided a pair of saddle members :53 which engage over the trunnions 32 and Each saddle member 63 is provided with an arcuate recess is forming a seat to prevent endwise movement of the saddle during the rotation of the idler rolls 3i and A weigh is provided for each saddle it and the weiglt is mounted on the lower end of a vertical roll -'Ihe upper end of the roll El is provided with an eye 52 in which the saddle i8 is loosely received.

A trumpet or sliver compressing member 55; is disposed with the reduced end thereof confronting the two rolls 3! and and the flared end of the trumpet 53 is secured to a vertical web or guard 54 w ion is provided with angularly disposed opposite end portions A base plate extends rearwardly frorn the web or guard 5 and a plate or flange El is secured to the lower end of the web or guard Ed and extends forwardly therefrom being secured by means of a fastening device 583 to the upper leg 22 of a bracket 5'5. A depending plate or guard is carried by the rear edge of the base plate 5 5 and coacts with the web or guard in providing a means to prevent the stray ends of fiber from engaging between the parallelizing rolls adjacent the ends of these rolls.

A condensin guide 8% is disposed between the output side of the rolls 33 and ti and the input side of the calendar rolls M. This condensing guide Gil is formed of upper and lower frustotriangular plates 5! which are connected together by end plates 62. The large end of the so confronts the output sides of the rolls and ll. The guide SE? is supported in the dcsired position relative to the two rolls 33 and 4-5 by means of a supporting bar 53 which is secured to the lower plate iii.

In the use and operation of this attachment, the two bracket members ii are mounted on the frame part Ed by tl e fasteni g devices The gear is mounted in a position to mesh with the calendar gear id which is commonly known as the carrier element. The rolls 3!, and ll are then mounted in th respective bearings which are slidably mounted within the guide slots 25 and E3 of the bearings 23 and 2%. The carding machine is then operated in the usual manner and as the sliver passes from the doiier cylinder into the calendar rolls ii, the sliver willpass through the trumpet 53 and between the first pair of rolls 3i and 35. The lower roll is positively driven through the hereinbefore described gear train whereas the upper roll 3| is an idler roll.

The two weights 5% will maintain the upper roll 3. in the desired contacting relation with the sliver as it moves between the two rolls 3| and 35. The gear train is so arranged that the lower forward roll M will rotate at a speed greater than the rear roll 55 so as to effect a drawing or pulling on the fibers in the space between the two rolls 35 and M. This drawing or pulling will have the effect of parallelizing the fibers which will then pass through the condensing guide into the calendar rolls.

ihe use of an attachment of this kind on a carding machine will make it unnecessary to pass the sliver through a drawing machine, the purpose of which is to make the sliver fibers parallel. It will therefore be apparent that this attachment will eliminate the drawing process which at present is performed by a separate machine. This attachment may be mounted on the present structure of a carding machine Without ai fecting the arrangement of the parts on the machine and at the same time eliminate the subsequent step of making the fibers parallel by the sliver through a drawing process.
