To all whom it may concern:

dan, France,have invented certain new and useful Improvements in Gig-Mills, (whiehhave been patented tome in France Novemin Belgium March '7, 1888, No. 80,913; in Germany July 27, 1889, No. 55,784; in Great Britain April 11, 1888, No. 5,394; in Switzerland February 19, 1889,

-l-his invention relates to giganills of that kind in which there is a rotatingdrum around which are arranged working or teaz'eling rolls having a varying rotary m'ovemcntindependout of the movement of the drum.

The characteristic feature ofthe present invention is thatsome of the teazeling-rolls'act in a reverse way to the others, although they are mounted on the same drum, which turnsonly in one direction 3y this means the cloth or goods can beteazeled or dressed with two setsv of napping-rolls on the same drum both in the direction of the nap and against the nap, which is indispensable in many goods and which has hitherto beeneil'ected either by the use of several drums turning in reverse directions to each other or by submitting the cloth more than once to the actionof the same drum, turning the cloth around end for end each time. liy these methods the t'cazeling in the two directions instead of being simultane ;u1s,as in my improvement, is eflectcd by successive operations, and there is a loss of useful ctl'ect, especially in dealing with [abrics for which a short thick nap is desired. For the purposes of my invention I arrange the working rollers the reverse of one another that is to say, with thepoints of the cards or tcazels on one roller in the direction of the rotation of the drum and the points of the card on the next following roller in the con- 'nap -that isto say, all the their points turned in the direction Which is Without risk of 'f'rettin'g 'trary direction or in some instances radial.

In such arrangement half of the rollers are provided with the teeth pointed in one direction and the other half with their teeth pointed in another direction. The relation of the rollers can be variedas, for instance, by arrang' I ing two or three rollers with all of their teeth working with the nap in succession with rollers with the teeth working against the nap the particular arrangement depending upon the nature of the fabrieto be treated and the cha'racterof finish required. Further, all the rollers-may be those which work against the cards that have the reverse of the rotation of the drum-which is of advantage for very light-fabrics, as it enables the machine to act more energetically the fabric.

In order to simultaneously strip or clean the cards of the two sets, of rolls having teeth differently arranged, I make use. of two sets of brushes or strippers actingsimultaneousl one inside and the other outside of the drum, and with this object the rollers which act in one drectionfor instance, those which act against the nap are arranged at-a, greater distance from the center than the others, and

the stripper placed outside the drum cleans one set of rollers, while the internal stripper cleans the other set.

In a machine constructed as above set forth it is necessary to provide ("or varying the energy of the cards1hat is to say, to give more or less of a. rotation to the working rolls in respect to. the movement of the drum. -lo securc this result with twoscts of rollers working in opposite directions, caclrroller-shaft is provided with a pulley off a diameter equal to that of the roller, the pulleys of one set of rolls being upon one vertical plane andv llmsu of the othcrset in another vertical plane, and the pulleys ot' the rollers that work with the nap are placed, as usual, outside the heads of the drum, and the pulleys of the rollers that work against the nap are, on the contrary, placed inside the heads, and one set of pul- .change in the speed varying the action of the two sets of cards at the same time and in the same proportion.

My invention also consists in other features of construction hereinafter set forth, and illustrated in the aecom panyin g drawings, in 'which I Figure 1 is a sideelevation of a gig-mill embodying my invention. Fig. 2 is an enlarged Y side elevation of part of the same, the line of the fabric not being shown in order to more clearly illustrate the positions of the ,belts. Fig. 3 is a diagrammatic illustration of the drum, rollers, stripper, and fabric supported directly by the two sets of rolls. 'Fig. 4 is a plan of the drum,showingone end of the same. Fig. 5 is a partial end view,'and Fig. 6 is a partial side-elevation, of the'drum, illustrating a modification in connection with the strippers. Fig. 7 -is a diagrammatic elevation of the drum, illustrating another modification. 1 Fig. 8 is an elevation of a modification illustrating two driving-shafts for driving the rollers. Fig. 9 is a plan illustrating a detail of Fig. 8.

Referring to Figs. 1 to 6, it will be noted that I provide-a drum A, consisting of ashaft 2) and two heads or disksj and napping-rolls having journals turning in bearings of the heads. The dru 111 may carry any desired numher of rollers, in the present instance fourteen, of which the seven marked T work against the nap and the seven marked T 2 work with the nap.

The drum Aderives the requisite action of rotation in the direction of its arrow 2 by any suitable means, as by a driving-belt passing from a shaft outside of the machine to a pulley on the shaft '0, as usual. A counter-shaft C is driven from the drum-shaft v, and in turn the napping-rolls are driven from the counter-shaft. Thus a cross-belt 0 passes from a pulley C on the drum-shaft o to a step-pulley 0. from"'which motion is imparted by gears s 5 (shown in dotted lines, Fig. 1)

to the counter-shaft, and onthecouuter-shaft G are mounted two pulleys 0 C The pulley O carries across-belt c, which passes around a series of pulleys B, Fig. 4,

pulleys B being on a vertical plane parallel to that in which the-pulleys B travel.

The pulley C earries' a belt 0 The arrangement of the pulleys B l and the rollerst'l" T will best be understood from Figs. 2 and 4, where it will be seen that tho pulleys B '3 are equal in diameter to the rollers T T that the pulleys ll are within the head of the drum and the pulleys 1 outside of said head. If the shaft 0 is stopped and the drum A driven in the direction of its arrow, Fig. 2, the cards of all the rollers have a backward development equal to the forward development of the drum and do not act upon the cloth D, which may be supported in any suitable manner upon the drum. This isthe minimum energy of the drum. If the shaft 0 is driven in the direction of its arrow 1, the rollers T will have their backward movements diminished and the rollers T will have their backward movements accelerated in the same proportion. The rollers will therefore operate upon the :fabric to effect an amount of work equiva lent or in proportion to the speed of the shaft C. Different speeds may be imparted to the shaft Gin relation to the rotation of the drum byshifting the belt c upon the pulleys C O L roo ishes or neutralizes to a proportional extent The fabric D may extend rou1id-the drum and be supported directly by both sets of rollers, as shown in Figs. 3 and 7; but in Fig. 1 I have shown it as elevated'at one point by passing over aguide-roller R. It is fed forward by two pulleys O C .upon two shafts 8 9, carrying the'pulleys 10 11, around which passes a belt O Where teazeling-rollers in two sets working in opposite directions are employed, it becomes necessary to provide two strippers, on for each set of teazeling-rollers.

As shown in Figs. 1 and 3, there is a retary exterior stripper 13 upon the shaft F, driven by a belt f from a pulley on the shaft v, and there is an interior stripper II, which is attached to hangers I1 depending loosely from the shaft 1; of the drum A, A screwpin a extends upward through an opening in each hanger and carries two nuts a a, by means of which the stripper maybe adjusted vertical-1y; As shown in the said figures, the stripper H consists of a card-plate having straight teeth, their ends lying in a curve; but instead. the internal stripper may be a revolving brush II, Figs. 5 and 6, upon a ping-roll has two pulleys, one at each.;,end,

side the rollers falls below the drum through .inch) from the center of the shaft r than the crating the two sets of rollers, the said shafts being connected by toothed wheels was, which are removably mounted upon the shafts for pulleys at the opposite end of the drum, and

shaft carried by hangers and driven from the shaft '0 through the medium of gears 11 z. In any case the flock or waste stripped from mthe space between the rollers.

In order to enable eaclrstripper to act to better advantage upon one set of nappingrollcrs alone, one set of rollers coincides with a larger and the other with a smaller circumference. Thus the rollers T are arranged in a-circle at a greater distance (say one-half an rollers T so that the former are acted upon only by the exterior stripper and the latter by the interior stripper.

Various modifications may be effected without departing from the spirit and nature of my invention. For example, instead of having each roller which works with the nap alternate with a roller which works against the nap I may place two, three, or more rollers working with the nap between two rollers working against the nap, and vice versa, the particular nature depending upon the fabric "to be treated. Again, itmaybe useful in some cases to actuate the oppositcl y-actin g napping-rollers by belts running over pulleys upon different shafts. Figs. 8 and 9 illustrate such aconstruetion In these figures 0 C are pulleys on two parallel shafts C O'foropthe purpose of interehan ging gears to Vary the relative speedsof the two shafts or to disconnect them when one is to be held stationary.

If desired, there may be two belts for each set of napping-rolls. In such case each napand onebelt passes around the pulleys at one end of the drum and the other around the guide-pulleys are so arranged to guide sai'd belts that one of the pulleys onthe shaft of each roller shall always be in contact with one of the belts. As shown in Fig. 8, a belt 0 passes around the pulleys of the rollers T at one end of the drum, beneath a guide-roll M at the right of the latter, up and over a pulleyO, and down and beneath a guide-roll M and another belt 0? at the opposite end of the drum passes around the pulleys T at that end, beneath .a guide-pulley M, up and around a pulley O, and down to the left of and then beneath a guide-pulley M. The belt (3 passes around the pulleys at one end of the rollers T passes arounda roll in line with the guide-roll M, around the pulley 0 down and at the left-of a pulley in line with the pulley M, and thence to the right, while thev belt 0', that passes around thepulleys of the rollers T at the opposite end of the drum, passes first beneath and at the right of the pulley on line with the pulley M, around the pulley C and down and to the left of and bearrangement,while more expensive than the .first described, offers advantages, as it permits the operation of teazelin g against-the nap to be effected independently of the teazeling with the nap. For instance, one of the toothed gear with the tooth a: by adjusting it upon its shaft, on which it is secured, as by a set-screw (5 when the action of the driving-pulley C u pen the teazeling-rolls T'immediately ceases, the other set of rollers T continuing to be actuatedfrom the pulley G which continues to revolve.

ley 0 through the medium of a pinion 1 of said shaft gearing with a toothed wheel g on the shaft of the pulley C a-cone-pulley on the shaft of the pulley 0 (shown in dotted lines) being belted to a driving-pulley (dotted lines) on the shaft '0.

The toothed wheels as .1," may be exchanged for others of different relative diameters, whereby the working energy against the nap is modified in its relation to the working en-, ergy with the nap. Other known means of varying the relative movement of the pulleys C C may be used instead of toothed wheels.

The use of two shafts for driving the two sets of rollers,with means for varying the relative movements of the toothed shafts, offers great facility in operation and regulation of the machine, adapting the latter to be used in operation upon-goods of different kinds.

For some purposes one set of rollsas, for

be used only as drawing-rolls for maintaining and regulating the tension of the fabric between the working rolls. tion is shown in Fig. 7, and is useful when the goods do not require simultaneous teazeling with apd against the nap. In this case the rollers '1" are fitted with cards having straight teeth or are covered with plush, emery, or other material which will exert a draft or take a hold upon the fabric. These rollers T may be driven by a fixed strap or belt 07, secured to the frame at one end, and at'the other to a tension deviee-as,-fo r instance, an adjustable hook at. v

\Vhere the speed of the fabric'and size of the driving-pulleys require it, it is necessary, in order to cause the cards of working rollers to work against the nap, to make the diameter of their pulleys B greater than that of the rollers themselves, and the difference should be in proportion to the forward speed of the fabric. Thus it will be understood that if the fabric is required to advance thirty-six feet per minute the rollers should turn backward the amount that the drum turns forward, less thirty-six feet. The other rollers TZ-whieh work with the nap, way first described by an independent belt.

It will be noted that the term working or card rollers wherever. employed in this neath apulley on line with the pulley M". This specification and claims Motion is imparted from the shaft of a pill-- instance those workin a ainstthena ma are driven in the is not confined to.

wheels, say the tooth 00, may be removed from i Such a modificateazeling-rollers, although it includes them, and includes such drawing-rollers as just described. I
