ARTHUR MELLOR, OF BRIGHOUSE, ENGLAND.

MACHINE FOR DRESSING SILK.

Specification of Letters Patent.

Patented Jan. 20, 1920.

Application filed August 26, 1919. Serial No. 320,036.

To all whom it may concern:

Be it known that I, Airline MnLLoR, a subject of King George V of Great Britain, residing at Brighouse, in the county of York, England, have invented new and useful Improvements in or Relating to Machines for Dressing Silk, of which the following is a specification.

This inventi'on'ha's reference to the dressing of silk fibers and has for its object the provision of an improved machine for obtaining continuous dressing of the fibers and consequently a larger production at a decreased cost.

According to my invention, I dispense withthe present automatic stripping drums at the receiving end of the machine where the boards containing the silk fiber are engaged with suitable traversing means and carried forward from one end to the opposite'end of the machine, and in lieu of said stripping drums employ a rotary stripping brush or card cylinder of suitable diameter which removes the combings of silk oil the endless working combs of the first endless section of combs as these are caused to travel forward over the said brush, the combs being guided at a suitable angle or angles above the brush in order that the latter may operate on the 'combings at two points or over a wider area. H Acting in conjunction with the rotary stripping brush is a card cylinder or doifer which strips the brush of the fibers removed from the working combs, the said card cylinder or doller being in its turn cleared of the fibersby a dofier knife or vibrating stripper device. The combings on a second endless section of working combs are stripped by a second rotary brush appropriately located so that the fibers removed from such traveling working combs by said brush are deposited by it on the combs of the first endless traveling section of Worl ing combs whereby the card cylinder or rotary stripping brush at the receiving. end of the machine serves to strip the fibers removed from both the first and second endless combing sections.

At the delivery end of the machine I provide a suitable combing cylinder which operates on the tufts of silk depending from the boards or boxes as they pass over same to the delivery end of the machine and acts to remove the nibs and short fibers from suchdepending tufts, the said cylinder bemg stripped by a rotary brush which is in turn stripped by a card cylinder. In conj unction with the card cylinder I provide a series of workers and strippers to thoroughly card the fiber, a fancy being employed to raise thefibers on the teeth of the card cylinder to facilitate removal by a doifer from which the fibers are suitably removed and deliv ered to a coiler can. It has previously been proposed to strip the second endless set of combs by a brush and transfer the strippings to the first set of combs, and also in circular dressing machines, to use a brush acting in conjunction with a card cylinder and doffing comb to remove the combined strippings from one endless set of combs, and no claim is herein made to such arrangements per as. V

The object and nature of the invention thus set forth will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims. 7

Figure 1 is a skeleton longitudinal sectional elevation of a continuous silk dressing machine embodying my improvements, and

Fig. 2 is a detached sectional elevation on an enlarged scale of portions of the stripping brush and first endless section of workin combs.

eferring to the drawings, a represents the first endless traveling section of wore ing combs and b the second endless traveling section of working combs each said section traveling in opposite directions as'indicated by the arrows. Such endless sections of working combs are common to this type of continuous silk dressing machine and form no part of my present invention.

0, 0 represent the carriages containing series of book boards or boxes (Z between which the silk fibers are nipped and from which the tufts of silk to be combed depend so as to be combed by the working combs as usual, the said carriages being fed one after the other into the machine at A and traversed therethrough from end to end by worms 6 engaging with racks on the upper sides of the carriages c, in the ordinary manner.

According to my invention, in lieu of the usual stripping drums located at the receiving end A of the machine, I employ a rotary stripping brush or card cylinder 7 of suitable diameter located near the end A of the machine and below the lower portions of the first endless section a of working combs which are guided at a suitable angle or angles above the said brush or card cylinder somewhat as shown in Figs. 1 or :2, in order that the latter may operate on the combings at two points or over a wider area. If desired, the endless chains carrying the working combs in the section a may be guided over a surface concentric with the upper portion of the card cylinder 7 so that the cylinder will operate on the combings over the whole of the quadrant thus formed instead of at two portions of its periphery as in the arrangement shown in Figs. 1 and 2.

In Figs. 1 and 2 the guide roller 9 at each side of the machine may be adjusted to vary the angle of the endless chains.

The card cylinder or brush 7' removes the combings of silk off the working combs on the section a as these travel over the said cylinder or brush. Acting in conjunction with the rotary stripping brush or card cylinder f is a card cylinder or dofi'er it which strips the cylinder or brush 7 of the fibers removed from the working combs and is in its turn cleared of the fibers by an oscillating doffer knife 2', the stripped fibers falling on to the ground or into a receptacle.

The combings removed from the tufts of silk depending from the book boards or boxes 0 by the second section b of traveling working combs which operate on the reverse sides of the tufts to the combs on the section a, are removed from such combs by a rotary brush or card cylinder is which is suitably located so that the fibers removed by said brush from the endless section of working combs will be deposited by it on the working combs of the first section a whereby the card cylinder or rotary stripping brush 7" serves to strip the fibers removed from both the first and second combing sections.

At the delivery end B of the machine, I provide a suitable combing cylinder Z adapted to operate on the tufts of silk depending from the books or boxes d as they travel over same to the delivery end of the machine and acts to remove the nibs and short fibers from such depending tufts.

The said cylinder Z is stripped by a rotary brush on and this is in turn stripped by a card cylinder at. In conjunction with the card cylinder at I provide a series of workers and strippers 0, p to thoroughly card the fiber carried around by the cylinder at. A fancy r is employed to raise the fibers on the teeth of the cylinder 9% to facilitate the removal. of same by a doffer s. From the doffer these fibers are removed by an oscillating knife t the sliver passing forward between nipping rollers 74 to a coiler can in any kn own manner.

By the means above described the fibers removed by the sections of working combs are removed therefrom and deposited at the receiving end of the machine, and the short fibers and nibs removed from. the depending tufts after being combed by the sections of working combs, are thoroughly carded and delivered in a sliver to a coiler can, whereby the production of the machine is increased at a decreased cost.

The working parts of the machine are driven at suitable relative speeds by gearing and chains, belts or cords, the drives being omitted for the sake of clearness.

The improvements above described are particularly adapted for continuous silk dressing machines of the fiat type shown, but a portion of the improvements, namely the combing and carding section at the delivery end of the machine may be applied to continuous dressing machines of the circular type.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a dressing machine, an endless traveling comb for operating on tufts of silk, a rotary stripping brush arranged below the return stretch of the said comb and operating to remove the combings from it, and means for diverting the said return stretch from a straight path where it passes over the said brush and thereby increasing the area of contact between the brush and the comb.

2. In a dressing machine, an endless traveling comb for operating on tufts of silk, a rotary stripping brush arranged below the return stretch of the said comb and operating to remove the combings from it, and guide rollers which divert the said return stretch from a straight path and permit it to engage with the periphery of the said brush in two places thereby increasing the area of contact between the brush and the comb.

3. In a continuous flat dressing machine, the combination of the endless traveling sections of working combs each operating on difi'erent sides of the tufts of silk the first section of working combs on its return traverse being diverted by guide rollers from a straight path to form anangle, a rotary stripping brush or card cylinder working in the said angle to operate on the working combs at two points or over a wider area, to remove the combings from said combs, a card cylinder or doffer working in conjunction with said cylinder to remove the fibers therefrom,

a revolving brush or card cylinder suitably located to remove the combings from the second endless section of working combs and deposit them on the working combs in the first endless section, a combing cylinder operating on the tufts of fiber after the combing operation proper to remove the nibs and short fibers, a brush for stripping the fibers from the combing cylinder, a carding cylin- In testimony whereof I afiix my Signature der adapted to strip the fibers from said ,1n the presence of two wltnesses. brush, Workers and strlppers operatlng in conjunction With the carding, cylinder to ARTHUR MELLOR' 5 thoroughlycard the fibers, and means eom- Vitnesses:
