GILL-BOX MACHINE FOR PREPARING FIBERS.

SPECIFICATION forming part of Letters Patent N 0. 633,793, dated. September 26, 1899. Application filed December 29, 189?". Serial No. 664,401. (No model.)

ain, residing at Staines, London, England, have invented certain new and useful Im-. provements in or Relating to Gill-Box Ma-' chines for Preparing Fibers,- of which the fol-' lowing is a specification.

This invention relates to that class of ma" chines known as gill-boxes foropeningand preparing fibers preparatory to combing and opened and parallelized. The gills, which is designed more especially for treating vegetable fibers, such as flax, hemp, china-grass, or the like.

The advantages obtained by the improved preparing-machine are principally in the softening action of lapping the material as it is drawn from the gills or teeth onto'an endless sheet or belt which is made to run over and encircle one of the drawing-rollers, (a second and similar endless sheet or belt running over and encircling the other drawing-roll,) so that the flax or other fiber is between the top and bottom sheets or belts, and as it is lapped around the top sheet consequently (by the continuous running between the drawing-rollers under pressure) is softened and have a surface speed superior to that of the feed-rollers or porcupine feed, clear away the greater part of the straw and impurities from the fiberfedon,and the straw, dtc. falls under the machine. At the same time the fiber is opened and lashed by the pins or teeth of the gills and so prepared for being drawn out into a sliver read y for the combing-machine, which latter will separate the longspinable fibers from the short or noil. For clean longscutched flax, which requires only opening up and drawing into lap or sliver, one or two pairs of ordinary feed-rollers are good; but

where tow in its tangled forxnis to be treated a porcupine roller working in a dish (which may be preceded or followed by a pair of feed-rollers) is advantageous.

In order that this invention may be easily understood, I will proceed to'fully describe same with reference to the drawings hereunto annexed.

Figure 1 is an end elevation-2. e., looking I in the direction of the arrow 1, Fig. 2of a gill-box machine having the presentimprovelrnents applied thereto and constructed and arranged to act according to the present invention. Fig. 2 is a longitudinal vertical'section on the line 2 2, Fig. 1. Fig. 3 is a local detail View showing the modified arrangement for feeding the fiber to the gills.

A is the frame or support.

B B are ordinary feeding-rollers which are -mechanically revolved in the usual or any suitablemanner, and E is the ordinary feedin gapron, passing around one of the rollers B.

C C are the gills, the same being ordinary screw-gills of the well-known character and arranged and acting as is well understood, and therefore it is not necessary to further illustrate same or more fully describe same here. If desired, these screw-gills may be made to advance at an increasing speed by means of variable screws, which impart the advancing motion to said gills.

D is a dabbing-brush extending across the fullwidth of the gills,'said brush being carried on the arm D, fixed to a shaft D journaled in bearings carried on the frame A,

D? D are cranks or arms extending from the opposite ends of said shaft D to which they are rigidly fixed, or only one arm D or D may be usedr 'E E are eccentrics or cams (slowly revolved by connection with some working part of the machine) wherebysaid arms D D are caused to oscillate said shaft D through part of a revolution, and consequently the brush D is raised and lowered into the teeth idle adjustable roller G. The roller F is' journaled in sliding blocks J,which1atter'are adapted to slide in or on the supports J and are adjustable thereon by means of the setscrews J while the roller G is similarly arrangedviz., is journaled in the slide-blocks K, adapted to slide on the support K and adjusted by means of the set-screws K -and thus the endless sheets or belts (which may advantageously be of leather) can be respectively stretched or adjusted as desired. Each of the supports J is pivoted on a standard J attached to the frame A, and is provided with a curved extension J, slotted at A setscrew 3 passes through this slotted extension into the frame 11. By means of these parts the roller F and belt II can be adjusted relatively to the belt I.

M is an idle resser-roller (carried by the arms M) resting against the belt H as the lat ter passes around the upper drawingroller F, and thereby guiding the fibers downward in between the belts II and I.

N N are the ordinary set-screws for adj usting the pressure on the drawing-rollers F G.

The drawing rollers F G may advantageously be fluted, and said rollers F G have a peripheral speed considerably greater than the speed of advance of the gills O,the advance of the latter in turn being much quicker than the peripheral speed of the feed-rollers B B.

The operation is as follows: The fibers are drawn out and opened and (after being acted on by the gills C) are led between the endless sheets H I and are formed into a lap around the endless sheet H, on which the fibers are continuously wound up, and as this lapped fiber passes around and around it is repeatedly pressed between the drawing-rollers F G, and is consequentlysoftened and very beneficially acted upon. As the first fibers appear between the belts II and I the attendant lifts them onto the belt 1-1. When the fiber reaches the other end of the belt H, it is guided down and again passes between the belts. After the formation of the lap beginsit goes on automatically. When a sufficient quantity of the fiber has accumulated on the bolt II, it is separated by pulling on same by hand and removed and on another machine is drawn out into a continuous sliver in readiness for the combing machine or may be otherwise removed or treated in any desired manner. I

In the modification shown in Fig. 3 the porcupine roller X (in combination and acting in conjunction with the dish Y) is introduced between the feed-rollers B B and the gills C in order to first open and straighten the fibers before they are acted on by the gills O and at the same time to allow the longer fibers to slip unbroken through the porcupine teeth of said roller X.

Many changes in the details of the machine may be made without departing from the spirit of my invention, and I wish it to be expressly understood that I do not limit myself to the exact details shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a gill box or machine for opening and drawing fibers, the combination of feeding devices, traveling gills, drawing-rollers, loose rollers, belts'passing over said drawing-rollers and said loose rollers, and a freely-swinging pressure-roller placed near the inner end of the upper belt, substantially as described.

2. In a gill box or machine for opening and drawing fibers, the combination of feeding devices, a porcupine roller and dish, traveling gills, a brush above said gills, means for oscillating said brush, fluted drawing-rollers, loose rollers, belts passing around said drawing-rollers and said loose rollers, means for adjusting said loose rollers to tighten or loosen said belts, means for adjusting the upper belt toward or away from the otherbelt and a freely-swinging pressure-roller, near one end of the upper belt substantially as described.
